Lower limb stress recording device

Abstract

A lower limb stress recording device comprises a lower limb brace unit, a lower limb stress sensing unit and a lower limb stress data recording and storing unit. The lower limb stress sensing unit comprises a machine body and a digital display assembly, wherein the machine body is provided with a stress sensor. The stress sensor senses an analog voltage signal and outputs the analog voltage signal to an analog-digital converter; the analog-digital converter converts the analog voltage signal into a digital signal after amplifying the analog voltage signal, and then outputs the digital signal to a central processing unit; the central processing unit converts the digital signal into stress value data and outputs the stress value data to a digital displayer for display. The stress value data obtained by the lower limb stress sensing unit are recorded and stored in the central processing unit; a curve chart of tested stress and a test process are displayed synchronously through connection between synchronous test and analysis software and a computer; test data can be imported in an EXCEL and other office software or the test curve chart can be saved in various formats for medical statistics and scientific research and analysis.

Description

technical field [0001] The invention relates to an electronic medical device, in particular to a lower limb stress recording device applied to patients with bone injuries. Background technique [0002] In medical clinical work, the early application of lower limb traction before surgery for patients with lower limb fractures can relieve pain, reduce tissue edema, and effectively prevent lower limb muscle tissue, blood vessels and nerves from being stabbed by the fracture end. However, the traction force determines the effectiveness of lower limb traction. Too little traction force does not work, and excessive traction can cause limb damage. In the past, when clinicians performed lower limb traction, they mainly relied on their own experience. The traction weight could not be accurately measured, recorded and controlled, and it was difficult to guarantee the therapeutic effect of traction. [0003] Scientific research has found that in patients with lower extremity fractures...
