Pulse condition acquiring contact device

Abstract

The invention discloses a pulse condition acquiring contact device, which comprises a bionic hand (1), a bionic hand support (2) and a pulse-taking platform (3). The bionic hand support (2) supports the bionic hand (1), and the bionic hand support (2) and an arm of a patient are fixed on the pulse-taking platform (3). The bionic hand (1) comprises flexible fingers (11) and array type pressure sensors (12) located at front ends of the flexible fingers (11). An inner cavity of each flexible finger (11) is divided into a plurality of air chambers along the periphery of the flexible finger (11), and the air chambers are communicated with various air channels of a pneumatic system. The array type pressure sensors (12) are connected onto a control system, and the control system drives air with certain pressure to be injected into the air chambers from the air channels of the pneumatic system according to pulse pressure information received from the array type sensors (12). The flexible fingers are designed integrally, hinge among joints is omitted, the fingers are controlled to move by high pressure air, energy loss in a pneumatic process is reduced, reliability is improved, and the service life of the flexible fingers is prolonged. Simultaneously, a three-cavity structure is adopted, so that movement with multiple degrees of freedom can be realized.

Description

technical field [0001] The invention relates to a medical device based on the theory of traditional Chinese medicine, in particular to a pulse condition collection contact device. Background technique [0002] The pulse diagnosis test contact device is an important part in the design of the traditional Chinese medicine pulse diagnosis system, and it is also a key difficulty. The performance of the pulse diagnosis contact part directly determines the accuracy and reliability of the pulse diagnosis. Traditional pulse diagnosis contacts are composed of rigid vertical pressure sensors, such as the utility model patent and publication number CN102258367A of the three-part pulse signal acquisition and analyzer with the publication number CN201624647U and the name of Cun, Guan and Chi. The patent application for the invention of the pulse-sensing instrument all adopts a purely mechanical structure, using motors or hydraulics to drive the mechanical parts to move up, down, left, and...

Traditional pulse diagnosis contacts are composed of rigid vertical pressure sensors, such as the utility model patent and publication number CN102258367A of the three-part pulse signal acquisition and analyzer with the publication number CN201624647U and the name of Cun, Guan and Chi. The patent application for the invention of the pulse-sensing instrument all adopts a purely mechanical structure, using motors or hydraulics to drive the mechanical parts to move up, down, left, and right. The disadvantage is that the structure is complex, the flexibility is poor, and it can only move in a strai
