Embodiment 1

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

[0036] The demodulation principle of the fiber Bragg grating sensor used in this embodiment: a wide-spectrum light source (such as SLED o...

Embodiment 2

[0053] The difference between this embodiment and the first embodiment 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 fit 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 bonding structure is simpler, the bonding effect is better, and the operation is more convenient. When in use, the fastening can be achieved only by the pushing force of the fingers. The other structure is the same as that of Embodiment 1, and will not be described here.

[0054] The measurement method using the above-mentioned finger muscle strength quantitative measuring instrument includes the following steps:

[0055] 1) Test preparation: Use weight measurement method to calibrate the finger muscle strength quantitative measuring instrument; select the appropriate finger fixing ring and fix it in the limit hole;

[0056] 2) Test...

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 specifically relates to a finger muscle strength quantitative measuring instrument and a measuring method thereof. Background technique [0002] Hand movement is one of the most important activities of the human body. It involves the work and life of patients. Among the changes in finger muscle strength caused by various diseases, the finger movement center occupies the most extensive area in the cerebral cortex, and the cerebral cortex alone is The exercise area of ​​the thumb is equivalent to 10 times the exercise area of ​​the entire thigh. Human hands can make billions of different actions, and these actions are closely connected with brain activity. Muscle strength examination is particularly important in diseases such as muscles, bones, nervous system, especially peripheral nervous system. Finger muscle strength examination is a commonly used assessment technique in early diagnosis and t...
