Embodiment Construction

[0027] The multi-channel pulse detection system based on the flexible array sensor of the present invention includes a flexible array sensor device, a pressure control detection device, a signal processing and acquisition system, a computer processor and a pulse map display and processing system, and is characterized in that it is based on bionics The flexible array sensor device designed by the principle. The device consists of a one-to-one combination of flexible array pulse transducers and air pressure sensors. The flexible array pulse transducers are made of silica gel and can be arranged horizontally in seven channels. The cross section of each channel is circular. The surrounding cavity is separated with silicone. The rear end of the flexible array pulse transducer is closed, and the front end is connected with seven air pressure sensors. It can effectively reduce the discomfort caused by the hard probe to the human body during the acquisition process. Because there is...

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...
