Abstract

The invention discloses a method and device for directly measuring articular surface pressure in real time, the device is composed of a flexible pressure sensor, a signal acquisition device and a signal output device, the flexible pressure sensor converts a pressure signal in a joint into an electric signal, and then the signal acquisition device and the signal output device are used for respectively acquiring and outputting electric signal data. By utilizing the characteristic that the sensor arranged in the joint can convert a pressure signal into an electric signal which can be output under a pressure condition, accurate measurement and real-time monitoring of the pressure change of the joint surface are realized. The device is suitable for various disease models, such as joint disc displacement, joint disc perforation, anterior cruciate ligament fracture, degenerative joint diseases and the like.

Description

technical field

[0001] The invention belongs to the field of biomechanics, and relates to a pressure measurement method and device, in particular to a method and device for directly measuring articular surface pressure in real time, which are composed of a flexible pressure sensor, a signal acquisition device and a signal output device. Mechanical properties of the articular surface of experimental animals under physiological state and different pathological states. Background technique

[0002] Joints play an indispensable and important role in maintaining the daily life and work of the human body. Today, with the general emphasis on health, joint diseases have attracted more and more attention because of their great impact on the quality of human life. Degenerative joint disease (DJD) is the most common joint disease and the main cause of physical disability. Its etiology is complex and diverse, and its pathological mechanism is still unclear. Although the comprehensive...
