Quantitative measuring instrument of finger muscle strength and measuring method thereof

Abstract

The invention discloses a finger muscle strength quantitative measuring instrument and a measuring method thereof and belongs to the technical field of diagnosis. The finger muscle strength quantitative measuring instrument comprises a muscle strength measuring unit and a signal acquiring and processing system; the muscle strength measuring unit comprises an elastic stressed arm, a support and a bottom plate, the support is fixed to the bottom plate, the elastic stressed arm is arranged at one end, away from the bottom plate, of the support to form a cantilever structure, a muscle stressed hole is arranged in the end portion of the cantilever structure, and a finger fixing unit is arranged in the muscle stressed hole. The measuring method includes 1), testing preparation; 2), testing, namely pressing the muscle stressed hole with a single finger in a continuous or impacting manner; 3), data processing. Finger muscle strength in optional directions, real-time quantitative measuring in the motion direction and special testing of the muscle strength of the single finger are realized, and intelligent muscle testing and evaluation are realized through auxiliary calculation and automatic conversion of computers are realized.

Description

technical field

[0001] The invention belongs to the technical field of diagnosis, and in particular relates to a quantitative measuring instrument for finger muscle strength and a measuring method thereof. Background technique

[0002] Hand movement is one of the most important activities of the human body, involving the work and life of patients. Among the changes in finger muscle strength caused by various diseases, the finger movement center occupies the largest area in the cerebral cortex. The movement area of ​​the thumb is equivalent to 10 times the movement area of ​​the entire thigh. The human hand is capable of billions of different movements, all of which are closely linked to brain activity. Muscle strength testing is particularly important in lesions of the muscles, bones, nervous system, especially the peripheral nervous system. Finger muscle strength examination is a commonly used evaluation technique in early diagnosis and treatment of various diseases and r...

Examples

Embodiment 1

[0035] Such as figure 1 As shown, the finger muscle strength quantitative measuring instrument of this embodiment includes a muscle strength measuring device and a signal acquisition and processing system, and the muscle strength measuring device includes an elastic force-bearing arm 1, a support 2 and a base plate 3, and the support 2 Fixed with the base plate 3, the elastic force-bearing arm 1 is arranged on the end of the support 2 away from the base plate 3 to form a cantilever structure, and the end of the cantilever structure is provided with a muscle force force hole 4, and the muscle force force force is A finger fixing device 5 is arranged in the hole 4, and the signal acquisition and processing system includes a fiber grating 6 connected to a muscle strength measurement device, a spectrum analyzer 7, and a data analysis system 8.

[0036] The demodulation principle of the fiber Bragg grating sensor adopted in this embodiment: the light with a certain bandwidth will b...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that the limiting hole 9 is a tapered hole, and the finger fixing device 9 includes a finger fixing ring 10 that can closely match the taper of the limiting hole, and the finger fixing ring is set according to different inner diameters. multiple, such as figure 2 As shown, the taper-fitting structure is simpler, the fitting effect is better, and the operation is more convenient. When in use, the fastening can be realized only by pushing the fingers. Other structures are the same as in Embodiment 1, and will not be described here again.

[0054] Use the measuring method of above-mentioned finger muscle strength quantitative measuring instrument, its step comprises:

[0055] 1) Test preparation: Calibrate the quantitative measuring instrument of finger muscle strength by weight measurement method; select a suitable finger fixing ring and fix it in the limit hole;

[0056] 2) Test: Press the muscle force hole wi...
