Problems solved by technology

Through the comparative study of the existing pulse condition sensors, some very critical problems need to be solved urgently: first, when using the pulse condition sensor to detect the pulse condition of the radial artery, it is difficult for the single-point sensor to determine the center position of the radial artery, resulting in The collected pulse signal is not necessarily the strongest point, and the pulse data lacks stability and comparability
Second, although the pressure sensor can simulate the tactile sense of the Chinese physician's finger pulse, it can only obtain the vibration information of the skin surface, resulting in insufficient comprehensive information
Third, there are also many photoelectric sensors to obtain pulse conditions. Photoelectric sensors have high resolution and high sensitivity. limitation

Abstract

The invention provides a traditional Chinese medical pulse condition sensor which merges photoelectricity and pressure and can acquire the strength, trend, shape, width, blood flow change and pulse wave parameters of a pulse condition from a radial artery. The pulse condition sensor consists of a shielding shell for encapsulating a photoelectric device, an elastic beam, a pressure strain gage and a sensor shell, wherein the shielding shell for encapsulating the photoelectric device is connected with the elastic beam; the elastic beam is respectively connected with the pressure strain gage and the sensor shell; a photoelectric sensor array with an infrared transmitting tube array and an infrared receiving tube array is arranged in the shielding shell; and a baffle is arranged between the infrared transmitting tube array and the infrared receiving tube array. The pulse condition sensor acquires pulse condition data in a non-invasive mode, reflects the blood flow change, is convenient to position and improved in description capacity and detection efficiency, and has small volume and high integrated level.

Description

(1) Technical field [0001] The invention relates to photoelectric technology, in particular to a traditional Chinese medicine pulse sensor integrated with photoelectricity and pressure. (2) Background technology [0002] Pulse diagnosis is one of the four diagnostic methods of traditional Chinese medicine, and occupies a very important position in the four diagnostic methods of traditional Chinese medicine. The usual method of pulse diagnosis in traditional Chinese medicine is that the doctor of traditional Chinese medicine touches and presses the radial artery of the patient's mouth with his finger, and feels the change of the patient's pulse wave by applying different pressures such as floating, medium and sinking with the finger. A series of pulse waves containing information such as the position, strength, trend, shape, width and rhythm of the pulse generated corresponding to pressures such as floating, medium and sinking are called pulse conditions. Through pulse infor...
