Description

Device for instructing lay persons in performing plunged abdominal compression CPR

technical field

The invention belongs to the medical field, and in particular relates to a device for guiding non-professionals to perform insertion type abdominal compression cardiopulmonary resuscitation.

Background technique

Cardiopulmonary resuscitation is the first aid operation after cardiac arrest. The effect of cardiopulmonary resuscitation directly affects the patient's recovery rate and quality of life after recovery. At present, the implementation of cardiopulmonary resuscitation is mainly done by medical staff or professionally trained first aid personnel. The cardiopulmonary resuscitation recommended by the cardiopulmonary resuscitation guidelines is chest compression-only CPR. Chest compression-only CPR refers to folding hands in the middle of the chest, with a compression frequency of not less than 100/min, and a compression depth of not less than 4-5cm .

At present, ZOLL, a professional first aid resuscitation product company, has launched a mobile app for needles to guide operators to perform chest compression resuscitation. Emergency personnel hold the mobile phone on the chest, start the program, and control the compression frequency and depth according to the app instructions. This allows more non-professional operators to perform chest compression resuscitation, however, the recovery rate of chest compression resuscitation is only 8%-10%. However, some new cardiopulmonary resuscitation techniques that are superior to chest compression resuscitation have not been popularized in the general population due to relatively high professional requirements for rescuers or requirements for emergency equipment (non-hands-on operation).

Interposed abdominal compression cardiopulmonary resuscitation (interposedabdominalcompressionCPR) is to cooperate with the chest and abdomen compression of the patient. The difference between chest compression and abdominal compression is half a cycle. The frequency of chest and abdomen compression is 100 times/min, and the depth of chest compression is 4-5cm. The depth of abdominal compression is 2-3cm, and the pressure of abdominal compression is about 40mmHg. Insertion abdominal compression cardiopulmonary resuscitation has a better perfusion effect on cardiopulmonary brain than chest compression resuscitation, and does not require first aid equipment, but it has relatively high professional requirements for rescuers and needs trained professionals to complete.

As shown in FIG. 1 , the device 100 for instructing non-professionals to perform inserted abdominal compression cardiopulmonary resuscitation is used to guide non-professional operators to perform inserted abdominal compression cardiopulmonary resuscitation on patients. The device 100 for guiding non-professional operators to perform abdominal compression cardiopulmonary resuscitation includes: a thoracic operation module 100a and an abdominal operation module 100b. The thoracic operation module 100a is used to instruct the thoracic operator to press the patient's chest, and the abdominal operation module 100b is used to instruct the abdominal operator to press the patient's abdomen. The chest side operation module 100a and the ventral side operation module 100b can be installed on mobile devices such as mobile phones, smart watches or ipads.

In this embodiment, the function of storing the chest-side operation module 100a and the abdomen-side operation module 100b is implemented by using two mobile phones equipped with the chest-side operation module 100a and the abdomen-side operation module 100b. For the convenience of describing the chest side operation module 100a and the ventral side operation module 100b, they are collectively referred to as operation modules.

The operation module includes: a collection unit 110 and a processing unit 120 .

The acquisition unit 110 includes: a displacement sensor and a frequency sensor. The displacement sensor is used to collect the value of the real-time compression depth when the operator presses the patient, and the frequency sensor is used to collect the real-time compression frequency value when the operator presses the patient.

In this embodiment, both the displacement sensor and the frequency sensor are built into the mobile phone.

The processing unit 120 is connected to the acquisition unit 110 and includes: a storage unit, a display unit, a communication unit, a comparison unit, an audio unit and a control unit. The processing unit 120 is the application software on the mobile phone.

The storage unit stores the values of the standard chest compression frequency, standard chest compression depth, standard abdominal compression frequency and standard abdominal compression depth for the operation of inserting abdominal compression cardiopulmonary resuscitation; stores a display screen and a selection screen; stores "ding", Acoustic signals "frequency too fast", "frequency too slow", "compression depth too deep" and "compression depth too small".

Among them, in this example, according to the 2010 Cardiopulmonary Resuscitation Guidelines and related literature, the standard chest compression frequency is defined as 100 times/min, the standard chest compression depth is 4-5 cm, the standard abdominal compression frequency is 100 times/min, and the standard abdominal compression frequency is 100 times/min. The pressing depth is 2-3cm.

The display unit is used to display the selection screen and the display screen. In this embodiment, the selection screen and the display screen are both presented through the screen of the mobile phone.

The selection screen allows the operator to select the compression site. If the operator chooses to press the chest, the operation module will be used as the chest side operation module 100a. If the operator chooses to press the abdomen, then the operation module will be used as the abdomen operation module 100b.

The display screen is used to display values of real-time compression frequency, real-time compression depth, standard chest compression frequency, standard chest compression depth, standard abdominal compression frequency and standard abdominal compression depth. After the operator selects the chest compression operation, the display screen displays the values of real-time chest compression frequency, real-time chest compression depth, standard chest compression frequency, and standard chest compression depth. The areas corresponding to other parameters are gray areas, and no values are displayed. After the operator selects the abdominal compression operation, the display screen displays the values of real-time abdominal compression frequency, real-time abdominal compression depth, standard abdominal compression frequency, and standard abdominal compression depth. The areas corresponding to other parameters are gray areas, and no values are displayed.

The communication unit is used for communication, and the communication unit in one operation module can be paired with the communication unit in another operation module to realize the communication function.

The comparison unit is used to compare the values of real-time compression depth and real-time compression frequency with the values of standard chest compression frequency, standard chest compression depth, standard abdominal compression frequency and standard abdominal compression depth to obtain a comparison result.

The audio unit is used to issue voice commands. In this embodiment, the voice commands are issued through the speaker of the mobile phone. The audio unit guides the operator to press by issuing a "ding" sound, and reminds the operator to correct the frequency of compression by issuing the sound of "too fast frequency", "too slow frequency", "too large compression depth" or "too small compression depth" and compression depth.

The control unit is used for controlling the audio unit to issue sound instructions. Among them, after the communication units in the two operation modules are paired and connected, the two control units are coupled, so that the rhythm of the "ding" sound issued by the two audio units differs by half a cycle, which is similar to the chest and abdomen compression of the plug-in abdominal compression cardiopulmonary resuscitation. the same rhythm.

Fig. 2 is a schematic diagram of the implementation of the inserted abdominal compression cardiopulmonary resuscitation in the embodiment of the present invention.

As shown in FIG. 2 , when performing abdominal compression cardiopulmonary resuscitation on the patient 3 , the operator 1 holds the mobile phone 200 a, and the operator 2 holds the mobile phone 200 b. Operator 1 and operator 2 place two mobile phones on the chest and abdomen of patient 3 respectively. Operator 1 presses the chest of patient 3 according to the prompt of mobile phone 200a, and operator 2 presses the patient's chest according to the prompt of mobile phone 200b. 3's abdomen for compressions.

Step S4-2, the operator 2 presses the abdomen of the patient 3 according to the voice command from the mobile phone 200b, makes a "ding" sound and presses once, and then enters step S5-2.

In step S5, the collection unit collects the pressing frequency and pressing depth of the operator. Then go to step S6.

In step S5-1, the collection unit of the mobile phone 200a collects the real-time chest compression frequency and real-time chest compression depth values of the chest of the patient 3, and then proceeds to step S6-1.

In step S5-2, the collection part of the mobile phone 200b collects the real-time abdominal compression frequency and real-time abdominal compression depth values of the patient 3's abdomen, and then enters step S6-2.

In step S6, the comparison unit compares the real-time compression frequency and real-time compression depth with the standard compression frequency and standard compression depth to obtain a comparison result, and then enters step S7.

Step S6-1, the comparison unit of the mobile phone 200a compares the real-time chest compression frequency and real-time chest compression depth values collected by the acquisition unit with the standard chest compression frequency and standard chest compression depth values to obtain a comparison result, and then enters step S7-1 .

Step S6-2, the comparison unit of the mobile phone 200b compares the real-time abdominal compression frequency and real-time abdominal compression depth values collected by the acquisition unit with the standard abdominal compression frequency and standard abdominal compression depth values to obtain a comparison result, and then enters step S7-2 .

In step S7, the control unit controls the audio unit to issue a voice command according to the comparison result.

Step S7-1, if the chest compression frequency and compression depth of the operator 1 are not the same as the standard, then go to step S3-1, the control unit will control the audio unit to make a sound to prompt "the frequency is too fast", "the frequency is too slow", If the voice command of "compression depth is too large" or "compression depth is too small", if the compression frequency and compression depth of the operator 1 are the same as the standard, then go to step S4-1.

Step S7-2, if the compression frequency and compression depth of the operator 2 on the abdomen are not the same as the standard, then go to step S3-2, the control unit will control the audio unit to make a sound to prompt "the frequency is too fast", "the frequency is too slow", If the voice command of "the compression depth is too large" or "the compression depth is too small", if the compression frequency and compression depth of the operator 2 for abdominal compression are the same as the standard, go to step S4-2.

This loops until the patient wakes up, then closes the application.

Wherein, if the operator's pressing on the patient completely matches the "ding" sound issued by the audio unit, the pressing frequency is the standard pressing frequency.

In addition, the collection unit may further include a pressure sensor for collecting the pressing force of the operator.
