Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device and method for measuring blood pressure and pulse wave. Background Art

[0002] With the development of economy, traditional sphygmomanometers generally use a single air bag. In order to measure more accurate blood pressure data, the area of ​​the air bag is generally set to be relatively large. Such a design is also convenient for users to operate. However, due to the large area of ​​the air bag, the human pulse wave data collected while collecting blood pressure will have a relatively large error. Therefore, in life, the design of sphygmomanometers generally only considers the accuracy of the measured blood pressure value and ignores the accuracy of the pulse wave data. If it is necessary to collect more accurate pulse wave values ​​in clinical practice, it is generally necessary to use a special instrument for collecting pulse waves for data collection. This method is not only not simple but also increases the production cost of the instrument. At the same time, it is not convenient in clinical application. If accurate pulse wave data is required, patients need to undergo a secondary examination, which increases the cost of medical treatment for patients and increases the workload of doctors. Now people's living standards have improved, the pace of life has accelerated, people are paying more and more attention to their health, patients are under great pressure to seek medical treatment, and doctors have long working hours and other problems.

[0003] Therefore, it is particularly necessary to design a device that can accurately measure blood pressure and pulse wave at the same time. Summary of the invention

[0004] The purpose of the present invention is to provide a working method of a smart ring and a smart ring, so as to analyze the physiological state of a human body in real time.

[0005] In order to achieve the above purpose, the technical solution adopted by the embodiment of the present invention is as follows:

[0007] Specifically, there are 2 to 6 pulse wave airbags respectively arranged on both sides of the blood pressure airbag.

[0008] Specifically, the width of the pulse wave airbag is 3-5 cm, the width of the blood pressure airbag is 10-20 cm, and the area of ​​the body part pressed by the pulse wave airbag is smaller than the area of ​​the body part pressed by the blood pressure airbag.

[0009] Specifically, the part of the body where the sleeve is rolled up to compress the body is the left wrist or the right wrist.

[0010] Specifically, the pulse wave airbag compression position corresponds to the positions of the three parts of Cun, Guan and Chi collected at the left wrist or right wrist joint when taking the pulse in traditional Chinese medicine.

[0011] Specifically, the sleeve is used to be wrapped around the body to compress the body part, which can also be the left arm or the right arm.

The blood pressure airbag and the pulse wave airbag work together to measure the systolic pressure SBP, the diastolic pressure DBP and the pulse pressure difference. The first pressure point equivalent to the floating pulse wave in traditional Chinese medicine pulse diagnosis is calculated by the calculation formula: DBP+1 / 4*(SBP-DBP); the second pressure point equivalent to the middle pulse wave in traditional Chinese medicine pulse diagnosis is calculated by the calculation formula: DBP+1 / 2*(SBP-DBP); finally, the third pressure point equivalent to the sinking pulse wave in traditional Chinese medicine pulse diagnosis is calculated by the calculation formula: DBP+3 / 4*(SBP-DBP);

[0015] 3) Close the through valve and inflate the pulse wave airbag through the air pump. When the pulse wave airbag is inflated to the first pressure point, the pressure is maintained for 15-30 seconds, and the first waveform data of floating is collected; when the pulse wave airbag is inflated to the second pressure point, the pressure is maintained for 15-30 seconds, and the second waveform data of centering is collected; when the pulse wave airbag is inflated to the third pressure point, the pressure is maintained for 15-30 seconds, and the third waveform data of sinking pulse wave is collected; finally, the first waveform data, the second waveform data and the third waveform data are collected to form a complete pulse wave.
