Multipath pulse condition detection device based on flexible array sensor

Abstract

The invention relates to the technical field of medical equipment and aims at providing a multipath pulse condition detection system capable of being well contacted with a flexible organization and drawing a pulse width and pulse wave three-dimensional conduction topographic map. The technical scheme is that a multipath pulse condition detection device based on a flexible array sensor is composed of the flexible array sensor, a pressure control device, a signal processing module, a signal collection module and a computer. The flexible array sensor is formed by correspondingly connecting flexible array pulse transducers and air pressure sensors one to one. The flexible array pulse transducers are made of silica gel and are horizontally arranged in a plurality of paths, the cross section of a cavity of each path of flexible array pulse transducer is round, and the periphery of each cavity is isolated through the silica gel. The pressure control device is used for leading the flexible array sensor to be tightly contacted with a flexible organization by increasing pressure. The air pressure sensors are sequentially output to the signal processing module, an analog-digital converter and the computer. The multipath pulse condition detection device based on the flexible array sensor is mainly applied to pulse condition detection.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-channel pulse condition detection system based on a flexible array sensor. Background technique [0002] As a key diagnostic technique in traditional Chinese medicine, pulse diagnosis has a long history and unique creativity. However, the inheritance of pulse diagnosis experience for thousands of years is mostly through oral methods, and there are few quantitative expressions or classifications. This may cause different doctors with different pulse condition information of the same patient to have different opinions, and the transmission and storage of the patient pulse condition information also have many inconveniences. In recent years, with the continuous deepening of the research on the objectivity of TCM pulse diagnosis, a variety of pulse analysis equipment have emerged. [0003] Existing pulse condition detection equipment generally uses piezoelectric sen...

Problems solved by technology

This design can realize pressure control very well, and output the three pulse signals of inch, guan, and chi, as well as the pulse channel shape signal. However, the design requirements of the composite sensor used in this design are relatively high, and the mechanical structure of the cantilever beam is complicated.
