Problems solved by technology

The cuff is inflated by air delivered through the plastic tube, which puts pressure on the pulse sensor, but the pressure of the cuff can have negative consequences, such as causing backflow of blood in the veins

Embodiment Construction

[0034] In the inventor's early research, a strained cantilever strain beam transducer was used as a pulse waveform detection instrument. Using this pressure sensor, the inventor's TCPD research group has built a pulse image database, which contains about 6000 pulse records. Due to the large size of this sensor, it is not suitable for multi-point detection, nor is it suitable for array arrangement. This motivates the inventors to develop a sensor, a pulse detector and a pulse detection method that can not only obtain reliable pulse patterns and related parameters, but also meet the diagnostic requirements of TCPD.

[0035] In the following, the present invention will be described in detail by taking a three-part nine-wait pulse detector that automatically provides contact pressure and controls the contact pressure in a closed loop as an example.

[0036] Removing the two main pressure sensors 1 and the two motors 7 in Fig. 2A is a single-unit pulse detector that can realize si...

Abstract

A Chinese-medicinal pulse state sensor, a pulse state tester with closed-loop control for testing the pulse pressure, and its test method are disclosed. Said pulse state sensor has a probe and two or more strain beams with both ends fixed to the surface of said probe and the semiconductor strain foil to form two or more attached sensors.

Description

technical field [0001] The present invention relates to the field of medical devices and detection methods, in particular to a Chinese medicine pulse condition sensor capable of accurately cutting the pulse according to the pulse diagnosis theory of traditional Chinese medicine and quantifying various information and parameters, a pulse condition detector and a detection method for closed-loop control of the pulse cutting pressure, and three parts and nine Pulse condition detector and detection method. Background technique [0002] Chinese medicine makes a diagnosis using information obtained through observation of the patient as a whole. In Chinese medicine, there are four diagnostic methods: looking, smelling, asking, and feeling. Among them, pulse diagnosis is one of the important diagnostic methods in Chinese medicine. When cutting the pulse, ask the patient to sit or lie on his back, stretch out his arms and place them close to the same level as the heart, with the pal...
