Bluetooth transmission type intelligent muscle strength tester

Abstract

The invention provides a Bluetooth transmission type intelligent muscle strength tester, comprising a muscle strength testing probe and an upper-computer muscle strength estimating device, wherein a Bluetooth sending module is arranged in the muscle strength testing probe, a Bluetooth receiving module is arranged in the upper-computer muscle strength estimating device, and the wireless data communication between the muscle strength testing probe and the upper-computer muscle strength estimating device is realized by using a Bluetooth protocol. The muscle strength testing probe comprises a battery, a power supply management module, a muscle strength testing sensor, a signal conditioning module, a microprocessor and the Bluetooth sending module. According to the invention, the wireless communication between the muscle strength testing probe and the upper-computer muscle strength estimating device is realized by using the Bluetooth protocol, a signal line and a cable line are unnecessary to connect, and the muscle strength testing probe can be conveniently placed into muscle groups to be tested at different positions in a testing process. In addition, the muscle strength estimating device is used for receiving data of the muscle strength testing probe in real time by means of a Bluetooth technology and accurately estimating and analyzing the muscle strength function of a testee, and can be suitable to multi-stage muscle strength determination.

Description

technical field [0001] The invention relates to medical instruments, in particular to a bluetooth transmission intelligent muscle strength tester using wireless bluetooth communication technology. Background technique [0002] Muscle strength is the ability of a muscle to contract voluntarily. Weakening or loss of muscle strength is called paralysis. Complete loss of muscle strength is called complete paralysis; incomplete loss of muscle strength is called incomplete paralysis. In order to facilitate the comparison of muscle strength, the six-level measurement standard formulated by the Medical Research Council (Medical Research Council) is generally used for functional assessment of muscle strength. Muscle strength function assessment has practical significance for guiding rehabilitation treatment, judging curative effect and prognosis. The most commonly used and internationally recognized muscle strength assessment method in clinical practice is the manual muscle test (...

AI Technical Summary

Problems solved by technology

The MMT method does not require special equipment, is easy to operate, and is suitable for testing the strength of different muscles. However, the classification is relatively rough, and it is not sensitive to changes in muscle strength. It is difficult to rule out the error of the subjective evaluation of the tester.
