Description

Wearable Vital Signs Monitor

technical field

The invention relates to a wearable vital sign monitor and belongs to the field of electronic applications.

Background technique

With the development of science and technology and the improvement of human living standards, health has always been a very important topic. For young people who are busy with work, they ignore the health problems of the elderly and themselves. There will be many hidden diseases. If they are not discovered early, the serious consequences will be unimaginable. Therefore, early detection and prevention are needed to reduce the pain caused by diseases to the elderly and reduce the pressure on the young. Young people will always I thought that no diseases would happen to me when I was young, but this is not the case. Many diseases will happen to young people, such as cerebral thrombosis, myocardial infarction, etc. are getting younger, but the elderly are inconvenient to travel, and the hospital procedures are relatively It is cumbersome and unwilling to go to the hospital for examination. Young people are usually busy with work and will not easily pay attention to their own bodies. Therefore, there is an urgent need for a portable and real-time inspection of their own health. Instrument, for It will be a good development direction for us humans.

Contents of the invention

The present invention proposes a wearable vital sign monitor, which can check one's own health status in real time and reduce the hidden danger of disease.

To achieve the above-mentioned purpose, the present invention adopts following technical scheme:

Wearable vital sign monitor, including: wristband (J), button (I), display screen (F), core system (K);

The core system (K) includes: piezoelectric sensor (A), temperature sensor (B), heart rate measurement module (C), blood pressure measurement module (D), single-chip microcomputer (S), vibration module (H), extended Card (G); as shown in Figure 1 and Figure 3.

Below in conjunction with Fig. 1, illustrate the working process of the present invention:

Bring the wristband (J) to the wrist of the human body, so that the core system (K) is downward, so that the piezoelectric sensor (A) can fully contact with the pulse, and the pressure generated by the pulse beating is received and transformed by the piezoelectric sensor (A) into electrical signals, and transmit the obtained electrical signals to the heart rate measurement module (C) and blood pressure measurement module (D) respectively, and calculate the corresponding data through the heart rate measurement module (C) and blood pressure measurement module (D) and then transmit them to the microcontroller In (S), the temperature sensor (B) transmits the signal to the single-chip microcomputer (S) in real time through the temperature of the skin contact, and displays the heart rate, blood pressure value and body temperature value on the display screen (F), and press the button (I) The preset values of heart rate, blood pressure and body temperature can be set. When the heart rate, blood pressure and body temperature exceed the preset values, the single-chip microcomputer (S) will start the vibration module (H) to vibrate, and the wrist will feel the vibration, reminding Changes in the health of the carrier.

The wristband (J) in this monitor is made of textile.

The monitor is also equipped with an expansion card (G), which is a large-capacity memory card, and records the heart rate, blood pressure and body temperature in real time and stores them in the expansion card (G).

Beneficial effects of the present invention:

The monitor can be carried in the human body anytime and anywhere without affecting the normal work and life of the person. For older people, it can monitor the physical condition at all times, prompt the changes of the body in advance, and prevent the occurrence of senile diseases. The production monitor is small in size, and it is easy for people of any age to operate and recognize the information on it.

Description of drawings:

Fig. 1 is a system block diagram of the present invention;

Fig. 2 is the appearance rendering of the present invention;

Fig. 3 is a position diagram of the core system of the present invention.

Detailed ways:

In order to make the technical method of the present invention clearer, the present invention will be further described in detail below in conjunction with FIG. 1 and the embodiments. The specific examples described here are only used to explain the present invention and are not intended to limit the present invention.

Example:

As shown in Figures 1, 2, and 3;

Assuming a 24-hour monitoring, first bring the wristband (J) to the wrist of the human body, so that the core system (K) is downward, so that the piezoelectric sensor (A) can fully contact with the pulse:

1. People do different exercises through their work and rest time in daily life, such as going up and down stairs, running, cycling, sleeping, etc. Different changes in the body will cause changes in heart rate, blood pressure and body temperature. Press the button (1) Preset values for heart rate, blood pressure and body temperature can be set;

2. When the pressure generated by the pulse beat is received, it is converted into an electrical signal by the piezoelectric sensor (A), and the obtained electrical signal is transmitted to the heart rate measurement module (C) and the blood pressure measurement module (D) respectively, and the heart rate measurement module (C) and the blood pressure measurement module (D) calculate the corresponding data and then transmit it to the single-chip microcomputer (S), and the temperature sensor (B) transmits the signal to the single-chip microcomputer (S) in real time through the temperature of the contact skin;

3. And display the heart rate, blood pressure and body temperature on the display (F). When any one of the heart rate, blood pressure or body temperature is higher or lower than the preset value, the microcontroller (S) will Start the vibration module (H) to vibrate, and the wrist will feel the vibration, reminding the wearer to be healthy.

Claims (3)

1. wearable vital sign monitors, comprises: wrister (J), and button (I), display screen (F), core system (K), is characterized in that:
