Wrist muscle strength tester based on Bluetooth communication

Abstract

A wrist muscle strength tester based on Bluetooth communication comprises a portable shell, a muscle strength testing sensor, a power source, a power management module, a signal conditioning module, a microprocessor and a Bluetooth sending module, wherein the muscle strength testing sensor is embedded on the bottom surface of the shell, and the power source, the power management module, the signal conditioning module, the microprocessor and the Bluetooth sending module are arranged in the shell. The power management module is connected with the power source and converts power voltage into voltage classes needed by electric components to be outputted to the electric components, an output end of the muscle strength testing sensor is connected with an input end of the signal conditioning module, an output end of the signal conditioning module is connected with an input end of the microprocessor, and an output end of the microprocessor is connected with an input end of the Bluetooth sending module. By the wrist muscle strength tester based on Bluetooth communication, two-way communication based on Bluetooth communication is achieved, the power source supplies power by a battery, bondage of a signal line and a power line is avoided, and the tester is more convenient to use.

Description

technical field [0001] The invention relates to an auxiliary medical instrument, in particular to a wrist muscle strength tester based on bluetooth communication. Background technique [0002] Muscle strength examination is the basic examination method for musculoskeletal system and nervous system lesions, especially for the assessment of muscle weakness caused by peripheral neuropathy. It is of great significance in neurology, neurosurgery, orthopedics, sports medicine and rehabilitation medicine. The most commonly used and internationally recognized muscle strength assessment method in clinical practice is manual muscle test (MMT). Although the operation of MMT is simple, the classification is relatively rough, often accompanied by errors in the subjective evaluation of the operator. Moreover, the force-measuring instruments adopted, such as a grip dynamometer or a pinch dynamometer, are relatively simple, can only measure hand muscle strength, and have relatively large ...

Problems solved by technology

Although the operation of MMT is simple, the classification is relatively rough, often accompanied by errors in the subjective evaluation of the operator.

Moreover, the force-measuring instruments used, such as the grip dynamometer or the pinch dynamometer, are relatively simple, and can only measure hand muscle strength, and the measurement error is relatively large.

Better muscle strength testing and training equipment, such as: Power Track II, Computer Interfaced Manual Muscle, Tracker Freedom Wireless Muscle Testing, etc., are expensive, complicated to operate, and difficult to promote and apply in clinical practice
