Description
Technical Field
The application relates to the field of sign detection, in particular to an in-ear sign detection device and system.
Background
Blood oxygen and body temperature are basic parameters for vital sign monitoring of patients in various departments in hospitals. The possibility to continuously and accurately monitor vital signs is an improved goal of current vital sign monitoring devices.
Currently, for body temperature monitoring, one way is to detect by wearing in-ear body temperature monitoring equipment. The in-ear body temperature monitoring device is similar to a headset in shape, and an infrared probe is arranged at the front end of the device. After the user wears the in-ear body temperature monitoring device, the infrared probe is positioned in the external auditory canal of the user, the temperature of the tympanic membrane can be obtained through infrared detection, and the temperature of the tympanic membrane can accurately reflect the core temperature of the human body.
In order to realize continuous monitoring of body temperature, the first problem to be overcome is the change of external temperature. Since the external temperature changes affect the body temperature measurement result, continuous body temperature monitoring needs to be performed on the premise that the external temperature changes are relatively stable. There is a prior art that a constant temperature heating assembly is provided in an in-ear body temperature monitoring device to ensure that the working environment temperature of an infrared probe is substantially stable, thereby reducing the influence of the environment temperature variation on the measurement result. However, when the ambient temperature changes, in order to monitor the body temperature in real time, the constant temperature heating component is continuously in a working state, so that the battery energy consumption of the in-ear body temperature monitoring device is increased, and the continuous service time of the device is greatly reduced.
Meanwhile, the existing in-ear body temperature monitoring device does not consider individual differences in external auditory canal shape among different users. When a user wears an in-ear body temperature monitoring device that does not match the shape of his external auditory canal, it is difficult to align the infrared probe to the tympanic membrane. Furthermore, the tympanic membrane temperature measured by the in-ear body temperature monitoring device has a certain difference from the actual tympanic membrane temperature, so that the core temperature of the human body cannot be accurately monitored.
Aiming at the problem that the existing in-ear body temperature detection equipment cannot accurately monitor the core temperature of a human body under some conditions because individual differences of external auditory canal shapes among different users are not considered, no effective solution is proposed at present.

An in-ear sign detection device is provided in the present invention. Fig. 1 is a schematic structural diagram of an in-ear sign detection device provided by the invention. As shown in fig. 1, the physical sign detection device comprises an infrared temperature measurement assembly 200 and a first mounting piece 100, wherein the infrared temperature measurement assembly 200 is mounted at one end, close to an eardrum, of the first mounting piece 100, the first mounting piece 100 has elasticity, when the physical sign detection device is worn, the first mounting piece 100 is positioned in an external auditory canal of a wearer, the infrared temperature measurement assembly 200 is aligned to the eardrum of the wearer through elastic deformation of the first mounting piece 100, and the infrared temperature measurement assembly 200 is used for detecting the temperature of the eardrum of the wearer.
Specifically, the physical sign detection device mainly comprises an infrared temperature measurement component 200 and a first mounting piece 100, wherein the infrared temperature measurement component 200 is mounted at one end of the first mounting piece 100. When the wearer wears the physical sign detection device, both the infrared thermometry assembly 200 and the first mount 100 are positioned within the external auditory canal of the wearer with the infrared thermometry assembly 200 facing into the ear, i.e., the infrared thermometry assembly 200 facing the eardrum. Since the first mounting member 100 has elasticity, which is adapted to be deformed with the shape of the external auditory meatus, the first mounting member 100 can accommodate the shape differences of different external auditory meatuses, including the shape differences of external auditory meatuses between different wearers and the shape differences of external auditory meatuses of the same wearer under different in-ear angles. On the one hand, the first mounting piece 100 has elasticity, can produce adaptive deformation along with different external auditory meatus, and then it is more even with external auditory meatus contact for external auditory meatus atress is more even, can not produce stronger oppression in the part and feel, makes different wearers all have better wearing experience. On the other hand, the first mounting member 100 has elasticity, and can be attached to the external auditory canal under different in-ear angles, so that a wearer can continuously adjust the in-ear angle of the first mounting member 100, and the infrared temperature measuring assembly 200 can be aligned with the eardrum of the wearer, and finally the infrared temperature measuring assembly 200 can accurately measure the temperature of the eardrum.
Therefore, the in-ear physical sign detection device provided by the invention adopts the elastic first mounting piece 100 as the mounting carrier of the infrared temperature measurement assembly 200, so that the device can adapt to different external auditory meatus shapes, and a wearer can adjust the in-ear angle of the first mounting piece 100, so that the infrared temperature measurement assembly 200 can be aligned with the eardrum of the wearer. The problem that the core temperature of a human body cannot be accurately monitored under certain conditions due to the fact that the individual difference of the external auditory canal shape among different users is not considered in the existing in-ear body temperature detection equipment is solved.
In some of these embodiments, the first mount 100 includes a central portion and a rim portion, the rim portion surrounding the central portion, the rim portion being made of an elastic material, the central portion being configured to support the rim portion.
Specifically, in the present embodiment, the central portion of the first mounting member 100 is mainly used to support the edge portion thereof, and the edge portion thereof is an elastic structure. Since the edge portion of the first fitting 100 is in contact with the external auditory meatus, when the edge portion is made of an elastic material, it can be deformed correspondingly with different external auditory meatus structures, thereby having an effect of adapting to different external auditory meatus structures. Meanwhile, the hardness of the central part is greater than that of the edge part, so that the first mounting piece 100 cannot generate excessive bending deformation on the whole, the infrared temperature measuring assembly 200 has a certain supporting effect, the whole equipment stretches into the external auditory meatus conveniently, and the whole structural stability of the equipment is improved. The material of the center portion may be a flexible structure using a flexible material or a rigid structure having a rigid material and having a shape close to that of the external auditory meatus, or the material of the center portion may be a nonmetallic structure using a nonmetallic material or a metallic structure using a metallic material. It should be noted that, when the central portion is made of a metal material, the infrared temperature measurement component 200 in the device should be prevented from being directly connected to the central portion, so that the data acquisition accuracy of the sensor in the infrared temperature measurement component 200 is prevented from being affected by the metal material. If other sensors are present in the device, it should also be avoided to connect the sensors directly to the central part. Meanwhile, the central portion should be reserved with mounting holes penetrating through both ends, so as to facilitate the data transmission line penetrating through the infrared temperature measuring assembly 200.
Accordingly, in other embodiments, the first mount 100 is made of an elastomeric material.
Specifically, in this embodiment, the first mounting member 100 is made of an elastic material, so that the elastic variation of the first mounting member 100 is larger, that is, the first mounting member can be deformed to a larger extent. Therefore, the first fitting 100 in this embodiment is more adaptable to different external auditory canal shapes, and thus can accommodate various external auditory canal shapes having large differences in shape.
In some embodiments, the elastomeric material is selected from the group consisting of thermoplastic elastomers and thermoset elastomers.
In particular, since the first mounting member 100 is required to be in direct contact with the skin of the external auditory meatus, the elastic material is required to have a non-toxic and environmentally friendly property. The elastic material may be selected from a variety of different types of elastomers, including thermoplastic elastomers and thermoset elastomers. Illustratively, among the thermoplastic elastomers, the elastic material may be selected from nontoxic and environment-friendly styrenic thermoplastic elastomers, polyurethane thermoplastic elastomers, and the like. In the thermosetting elastomer, the elastic material can be nontoxic and environment-friendly silica gel, etc.
Further, in order to obtain a good wearing effect, the elastic material should be provided with appropriate hardness and elasticity.
In one embodiment, the hardness of the elastic material may be 10A-50A. There are various ways of measuring hardness, and in this embodiment, only the shore hardness is used as an example. The hardness represents whether the material is easy to deform. When the shore hardness of the elastic material is between 10A and 50A, the first mounting member 100 can deform along with different external auditory meatus shapes, and has a certain supporting property for the infrared temperature measuring assembly 200 without excessive bending deformation.
In one embodiment, the elastic material has an elastic modulus in the range of 1MPa to 2GPa. The elastic modulus reflects the recovery capability of the material after deformation. When the elastic modulus of the elastic material ranges from 1MPa to 2GPa, the acting force generated by the first mounting piece 100 on the external auditory canal after deformation is moderate. At this time, the wearer does not feel that the external auditory canal has a large feeling of compression, and the first mounting member 100 and the external auditory canal have a certain frictional force therebetween, so that the first mounting member 100 can be stabilized in the external auditory canal and cannot easily fall off.
In another embodiment, the hardness of the elastic material is 10A-50A and the elastic modulus of the elastic material is in the range of 1MPa-2GPa. In particular, in the present embodiment, the hardness and elasticity of the elastic material meet the above requirements at the same time, thereby giving the wearer a better use experience.
In some embodiments, the infrared temperature measurement assembly 200 comprises an infrared thermopile sensor and a first temperature sensor, wherein the infrared thermopile sensor and the first temperature sensor are mounted at one end of the first mounting member 100 close to the eardrum, the first temperature sensor is positioned at one side of the infrared thermopile sensor close to the first mounting member 100 and is used for detecting the cold junction working environment temperature of the infrared thermopile sensor, and the infrared thermopile sensor can be aligned with the eardrum of a wearer through elastic deformation of the first mounting member 100 when the sign detection device is worn, and is used for detecting the eardrum temperature of the wearer.
In this embodiment, a specific infrared temperature measurement assembly 200 is provided. The infrared temperature measurement assembly 200 mainly includes an infrared thermopile sensor and a first temperature sensor. The infrared thermopile sensor is aligned to the eardrum when in use and used for detecting the temperature of the eardrum, and the first temperature sensor is used for detecting the temperature of the cold junction working environment of the infrared thermopile sensor. Through the cold junction working environment temperature of the infrared thermopile sensor, the eardrum temperature detected by the infrared thermopile sensor can be compensated and corrected, and the influence of environment temperature change on a measuring result is reduced, so that the eardrum temperature is more accurately determined. Compared with the prior art, the infrared temperature measuring assembly 200 in the embodiment can reduce the power consumption of the detecting device by ensuring the constant working temperature of the temperature measuring assembly through the heating assembly.
Fig. 2 is a schematic structural diagram of an in-ear sign detection device in some embodiments of the invention. Referring to fig. 2, the sign detecting apparatus provided in this embodiment further includes an oxygen measuring component 400 and a second mounting member 300 on the basis of the infrared temperature measuring component 200 and the first mounting member 100, the second mounting member 300 is mounted on the first mounting member 100 and located at an end of the first mounting member 100 away from the infrared temperature measuring component 200, the second mounting member 300 has a mounting surface on which the oxygen measuring component 400 is mounted, the second mounting member 300 has elasticity in a direction perpendicular to the mounting surface, and when the sign detecting apparatus is worn, the oxygen measuring component 400 can be attached to the tragus of a wearer by elastic deformation of the second mounting member 300, and the oxygen measuring component 400 is used for detecting the oxygen concentration of the blood of the wearer.
In particular, the above embodiments mainly describe that the physical sign detecting device includes the infrared thermometry component 200, and the device has a function of detecting the temperature of the eardrum of the wearer. In this embodiment, the sign detection device may also perform the function of detecting the blood oxygen concentration of the wearer, which is mainly performed by the blood oxygen measuring assembly 400. The blood oxygen measuring assembly 400 is mounted on the mounting surface of the second mounting member 300, and the second mounting member 300 is connected to the side of the first mounting member 100 remote from the infrared temperature measuring assembly 200. After the testing device is worn, the first mounting member 100 is positioned within the external auditory canal and the second mounting member 300 and the blood oxygen measurement assembly 400 are positioned substantially at the external auditory meatus, with the mounting surface of the second mounting member 300 being substantially parallel to the tragus. The blood oxygen measurement assembly 400 may be relatively tightly fitted to the tragus under the influence of the second mount 300.
In some of these embodiments, the second mount 300 is made of an elastomeric material and the blood oxygen measurement assembly 400 includes a blood oxygen sensor.
Specifically, in the present embodiment, the elastic material of the second mounting member 300 is selected according to the same criteria as the first mounting member 100. The elastic material needs to have characteristics of non-toxicity and environmental protection. The elastic material may be selected from a variety of different types of elastomers, including thermoplastic elastomers and thermoset elastomers. Illustratively, among the thermoplastic elastomers, the elastic material may be selected from nontoxic and environment-friendly styrenic thermoplastic elastomers, polyurethane thermoplastic elastomers, and the like. In the thermosetting elastomer, the elastic material can be nontoxic and environment-friendly silica gel, etc. And the hardness of the elastic material is 10A-50A, and the elastic modulus of the elastic material is 1MPa-2GPa.
In some embodiments, the sign detection device further comprises a data processing unit and a communication unit, wherein the communication unit comprises a wireless communication unit and/or a wired communication unit, the infrared temperature measurement assembly 200 and the blood oxygen measurement assembly 400 are connected with the data processing unit, and the data processing unit is used for sending sign data to an external data processing and/or storage device through the communication unit, wherein the sign data comprises eardrum temperature and/or blood oxygen concentration.
In the above-described embodiments, it is mainly described that the sign detection apparatus mainly has the eardrum temperature detection function and the blood oxygen concentration detection function. On this basis, the detected eardrum temperature and blood oxygen concentration data need to be derived. Thus, in this embodiment, the sign detection device also has a communication function. Specifically, after the infrared temperature measurement component 200 and the blood oxygen measurement component 400 acquire the sign data, the sign data is transmitted to the data processing unit, and after the data processing unit performs preliminary processing on the sign data, the sign data is transmitted to the external data processing and/or storage device through the communication unit.
Wherein, because the volume of sign detection equipment is less, data processing unit can adopt MCU (Microcontroller Unit, micro-control unit) that the volume is less. The Communication unit may employ a wireless Communication unit to implement wireless Communication functions, such as bluetooth, NFC (NEAR FIELD Communication) tag, etc. The communication unit may also be a wired communication unit, and an interface connected to the wired communication unit needs to be provided on the physical sign detection device for connecting to a corresponding data transmission line. The external data processing device comprises a common computer and other terminals, and the physical sign data can be processed through the computer and other terminals and then fed back to the user. The data processing unit directly transmits the vital sign data to the external data processing equipment, so that the effect of monitoring vital signs in real time can be realized. Meanwhile, the data processing unit can also transmit the sign data to an external storage device for storage, and the sign data can be called when needed. Accordingly, the communication unit may employ a combination of a wireless communication unit and a wired communication unit, and thus have functions of both wireless communication and wired communication.
Further, the communication unit may also include a voice communication unit to facilitate remote voice communication between the wearer and others. Illustratively, the wearer may communicate directly with the physician through the sign detection device in a hospital, home, outdoors, or other setting where remote voice communication is desired. Therefore, in an embodiment, the sign detection device further has a communication function of a traditional earphone, so that a doctor can conveniently monitor and guide the sign of the wearer or feed back the sign data analysis result in real time.
Further, in some of these embodiments, the data processing unit for sending the vital sign data to the external data processing and/or storage device via the communication unit comprises the data processing unit for adding a time stamp to the vital sign data and sending the vital sign data with the time stamp to the external data processing and/or storage device.
Specifically, in this embodiment, the data processing unit does not simply send the sign data to the external device, but adds a time stamp to the sign data to characterize the acquisition time of each piece of data during data preprocessing. Through the time stamp, the physical sign states of the wearer at different moments can be determined more accurately, and physical sign data acquired at different time periods can be integrated and synchronized. Meanwhile, the fact that the same wearer can use a plurality of physical sign detection devices is considered, and physical sign data acquired by different physical sign detection devices can be integrated and synchronized through time stamps.
In some embodiments, the sign detection device further comprises a second temperature sensor connected to the data processing unit, the second temperature sensor being located at an end of the second mounting member 300 remote from the first mounting member 100 for detecting an external ear environment temperature of the wearer, and the data processing unit being further configured to detect an eardrum temperature of the wearer through the infrared thermometry assembly 200 when the external ear environment temperature change rate is less than a preset threshold.
Specifically, with continued reference to fig. 2, when the sign detection device is worn, the second mount 300 is positioned approximately at the external auditory meatus of the wearer, and the second temperature sensor is positioned outside the external auditory meatus, so that the external ear environment temperature of the wearer can be detected. The second temperature sensor transmits the detected external environment temperature to the data processing unit, and the data processing unit can control the working state of the infrared temperature measuring component 200 according to the external environment temperature. The infrared thermometry assembly 200 generally detects a relatively accurate eardrum temperature when the ambient temperature is stable. Therefore, when the data processing unit judges that the change rate of the outdoor environment temperature is greater than the threshold value, the data processing unit judges that the environment temperature is unstable and further judges that the eardrum temperature acquired by the infrared temperature measuring assembly 200 is not accurate enough, and when the data processing unit judges that the change rate of the outdoor environment temperature is less than the threshold value, the data processing unit judges that the environment temperature is stable and further judges that the eardrum temperature acquired by the infrared temperature measuring assembly 200 is accurate. The data processing unit can screen the eardrum temperature data according to the standard, and only relatively accurate eardrum temperature data is reserved.
In some embodiments, the sign detection device further comprises a position sensor connected to the data processing unit, the position sensor is located at an end of the second mounting member 300 away from the first mounting member 100 and is used for acquiring position information of the sign detection device, and the data processing unit is further used for judging whether the sign detection device is located in the ear of the wearer according to the position information, and detecting the eardrum temperature of the wearer through the infrared temperature measuring assembly 200 and/or detecting the blood oxygen concentration of the wearer through the blood oxygen measuring assembly 400 when the sign detection device is located in the ear of the wearer.
Specifically, in this embodiment, the position sensor is mainly used to detect the position of the sign detection device, so that the data processing unit can conveniently determine whether the sign detection device is in the ear, and therefore, the position sensor may also be referred to as an in-ear detection sensor. When the physical sign detection equipment is not in the ear, the data processing unit controls other parts to stop working, so that the power consumption of the equipment is reduced, and the acquisition of wrong physical sign data is avoided.
In the above embodiment, the infrared temperature measurement assembly 200 includes an infrared thermopile sensor and a first temperature sensor, and through the cold junction working environment temperature of the infrared thermopile sensor, the eardrum temperature detected by the infrared thermopile sensor can be compensated and corrected, so that the influence of the environment temperature change on the measurement result is reduced, and the eardrum temperature is determined more accurately. The compensation correction process described above may be performed by a data processing unit in the sign detection device. Thus, in a further embodiment, the infrared thermopile sensor and the first temperature sensor are both connected to a data processing unit for correcting the detection result of the infrared thermopile sensor based on the detection result of the first temperature sensor.
Accordingly, in another embodiment, the compensation correction procedure may also be performed by an external data processing device, i.e. the data processing unit in the vital sign detection device, solely for transmitting the eardrum temperature data and the cold junction operating environment temperature data to the external data processing device.
Since the sign detection device includes the infrared temperature measurement assembly 200, the blood oxygen measurement assembly 400, and the data processing unit at the same time in some embodiments, the sign detection device has both the eardrum temperature detection and blood oxygen concentration detection functions, and also needs to transmit sign data to an external device through a wireless transmission unit. In order to reduce the instantaneous power consumption of the vital signs detection device, in a further embodiment the data processing unit performs the acquisition and transmission of the different vital signs data in an asynchronous manner. Specifically, blood oxygen collection, body temperature collection and wireless transmission do not work at the same time, so that lower transient power consumption is ensured. For example, blood oxygen is collected at time t 1, blood oxygen information is wirelessly transmitted at time t 2, body temperature is collected at time t 3, body temperature information is wirelessly transmitted at time t 4, and the sequence and time interval of t 1、t2、t3 and t 4 can be flexibly set.
The structural features of the sign detection device and its inclusion of functional components have been more fully described by the several embodiments described above. Accordingly, in order to ensure the operation of the functional components, it is also necessary to configure a power supply, a power supply circuit, and a connection line connecting the respective functional components in the sign detection apparatus. The power supply typically employs a small battery. The battery may be disposed at an end of the first mounting member 100 remote from the infrared temperature measurement assembly 200 at a position close to the second mounting member 300, and may be disposed at a position of the second mounting member 300 remote from the first mounting member 100. Meanwhile, a connection line connecting the infrared temperature measuring assembly 200 and the data processing unit needs to pass through the first mount 100.
At the same time, the physical sign detection device can also be provided with a shell structural member for installing functional components. Illustratively, the physical sign detection device may have a first housing structure for mounting the infrared thermometry assembly 200, the first housing structure being connected to the first mounting member 100 at an end thereof near the eardrum, while the first housing structure should be designed to be smaller in size, not only with a smaller diameter than the first mounting member 100, but also with a smaller diameter than the usual external auditory meatus. The physical sign detecting apparatus may further have a second housing structure for mounting the battery, the second housing structure being connected to an end of the first mounting member 100 remote from the first housing structure, and the second mounting member 300 may be mounted at one side of the second housing structure and protrude from the second housing structure. The physical sign detection device may further have a third housing structure for mounting the data processing unit and the communication unit, the third housing structure being connected to a side of the second housing structure remote from the first mounting member 100 and may be integral with the second housing structure.
The technical scheme in the invention is further described by a specific embodiment.
Fig. 3 is a schematic structural diagram of an in-ear sign detection device according to an embodiment of the present invention. Referring to fig. 3, in one embodiment, the in-ear sign detection device includes an infrared thermopile sensor 210, an infrared thermopile cold junction ambient temperature sensor 220 (corresponding to a first temperature sensor), an external ambient temperature sensor 540 (corresponding to a second temperature sensor), an blood oxygen sensor 410, an in-ear detection sensor 530, an NFC tag 550, a battery 510, a power circuit, wireless and wired communication circuits, flexible structures (corresponding to the first and second mounts 100 and 300), a printed circuit board 520 with integrated microprocessor, and the like.
The elastic materials of the first and second mounting members 100 and 300 may be nontoxic and environment-friendly styrene thermoplastic elastomers, polyurethane thermoplastic elastomers, silica gel, etc. The first mount 100 and the second mount 300 may be made of the same or different elastic materials.
Further, the diameter of the first mounting member 100 may be designed to be about 5mm and the length may be designed to be about 1cm, the design location being between the infrared thermopile sensor 210 and the structural member on which the battery 510 is mounted, being part of the housing structural member. When the ear drum is worn, an adult holds the auricle and lightly pulls the auricle backwards and upwards, a child holds the auricle and lightly pulls the auricle backwards and downwards, so that the auditory meatus is basically in a straight-through state, the first mounting piece 100 and the infrared thermopile sensor 210 are placed into the position of 1/3 of the external auditory meatus inwards, after the pulling force on the ear is removed, the first mounting piece 100 is properly deformed along with the different shapes of the external auditory meatus, and a wearer can ensure that the infrared thermopile sensor 210 is basically opposite to the tympanic membrane part of the ear through adjustment.
The blood oxygen sensor 410 is loaded above the second mounting member 300, and the second mounting member 300 has a size slightly larger than the size of the blood oxygen sensor 410, and the second mounting member 300 may be a continuous part of the equipment casing or may be a separate structural member mounted on the equipment casing. The second mount 300 is made of an elastic material having good elasticity, which can change the longitudinal dimension by elastic deformation. Thus, the blood oxygen sensor 410 can be well fitted to the inside of the tragus in the case of different tragus sizes and depths of the external auditory meatus.
The infrared thermopile sensor 210, the infrared thermopile cold junction ambient temperature sensor 220, and the blood oxygen sensor 410 are all connected to a printed circuit board 520 (PCBA) placed at the outermost side through flexible cables, and the external ambient temperature sensor 540 and the in-ear detection sensor 530 may be integrated onto the PCBA, which may further integrate the NFC tag 550 and a BLE (bluetooth) communication unit (including a BLE antenna), may further integrate a wired communication unit, and may further integrate a battery and a power management unit.
It should be noted that the foregoing is merely exemplary. The dimensions of the first mount 100 may also be 4.5mm in diameter and 0.7mm in length, for example. The size and shape of the second mount 300 may also vary as long as it covers the size of the blood oxygen sensor. If the second mount 300 is oval, the major axis of the oval is greater than 5.5mm and the minor axis is greater than 2mm. The components integrated with the PCBA may be disposed at other positions, for example, the external environment temperature sensor 540 may be disposed on a structure exposed outside the ear, or the NFC tag 550 may be separately mounted on a structure exposed outside the ear. In-ear detection sensor 530 may be disposed near blood oxygen sensor 410, near infrared thermopile sensor 210, or the like. When the above components are not integrated on the PCBA, then they are connected to the PCBA by a cord.
Accordingly, the sign detection device may also integrate the audio portion of a conventional earphone for remote voice communication.
The in-ear sign detection device provided by the above embodiment has the following technical effects:
1. For the acquisition of eardrum temperature, a rigid infrared detection element (infrared thermopile sensor 210, infrared thermopile cold junction ambient temperature sensor 220) is integrated into one end of the first mount 100. When worn, the first mounting member 100 can accommodate bending of different shapes of human ear canal, ensuring that the infrared detection element is substantially facing the tympanic membrane in the ear canal.
2. For blood oxygen collection, the blood oxygen sensor 410 is arranged near the tragus position, and the blood oxygen sensor 410 is supported by the elastic second mounting piece 300, so that good fit between the blood oxygen sensor 410 and the tragus is ensured, and when the ear moves, the blood oxygen sensor 410 is static relative to the tragus, and further, the signal quality is ensured.
3. To ensure timely sensing of changes in ambient temperature, an ambient temperature sensor 540 is integrated with the sign detection device facing the outside of the ear. When the sensor temperature indicates a large change, the environment in which the human body is located is considered to be changed, such as from indoor to outdoor. When the sensor temperature is maintained for a period of time, such as 5-20 minutes, the environment of the human body is considered to be constant. When the external environment temperature is constant, the system considers that the measured value is more accurate. Through the integration of the sensor, the technical effect of intelligently screening the accurate values of the measured body temperature and blood oxygen is realized.
4. The temperature correction data of the infrared detection cold junction environment, such as common room temperature 26 ℃ and 20 ℃, is adopted, and when the temperature is in a relatively slow or constant time, a proper temperature compensation curve is selected according to the temperature acquired by the infrared thermopile cold junction environment temperature sensor 220, so that the temperature read by the infrared thermopile sensor 210 is accurate, and the working environment temperature stability of the infrared thermopile sensor 210 is ensured without adopting other structures, thereby avoiding structural redundancy and additional power consumption.
5. In-ear detection sensor 530 is integrated to reduce device power consumption and avoid acquisition of erroneous vital sign data. The NFC tag 550 is integrated so as to realize 'touch and talk', which is convenient to use.
6. Blood oxygen collection, body temperature collection and wireless transmission do not work at the same time, so that lower transient power consumption is ensured. If the blood oxygen is collected at the time t1, the blood oxygen information is wirelessly transmitted at the time t2, the body temperature is collected at the time t3, the body temperature information is wirelessly transmitted at the time t4, and the sequence and the time interval of the t1, the t2, the t3 and the t4 can be flexibly set.
Based on the in-ear sign detection device provided by the embodiments, the invention further provides an in-ear sign detection system. The sign detection system comprises two in-ear sign detection devices provided in the present invention. Since the sign detection device can be adapted to external auditory meatus of different shapes, each sign detection device can be adapted to both ears. The wearer can wear sign check out test set simultaneously in both ears, carries out the sign monitoring simultaneously through two sign check out test sets, synthesizes two sign data, can obtain more accurate sign monitoring result.
Because the external auditory canal structure of the two ears has symmetry, the specific structure of the two physical sign detection devices can be symmetrically designed, so that the two physical sign detection devices are respectively applicable to the left ear and the right ear. At this time, the sign detection device has a higher degree of matching with its corresponding ear.
Specifically, the sign detection system may further include a storage charging device for storing the two sign detection devices and charging the sign detection devices when storing. Any one of the two sign detection devices can work normally after being worn, the other sign detection device can be placed in the storage device for charging, and data can be exported, so that continuous real-time monitoring of vital sign signals is guaranteed.
