A device for detecting maximum muscle strength of biceps brachii

Abstract

The invention provides a device for detecting the maximum muscle strength of the musculus biceps brachii, relating to the technical field of detection devices, and filling up the blank of the device for detecting the muscle strength of the musculus biceps brachii. The device comprises a bracket, wherein a hand placing supporting plate, a crown block and a steel wire rope are arranged on the bracket, the first end of the steel wire rope is arranged at the position close to the hand placing supporting plate, and the second end of the steel wire rope bypasses the crown block to be connected witha tension sensor; an included angle alpha is formed between the hand placing supporting plate and the plane where the upper side of the bracket is located. When the device is used, the upper arm is placed at the upper side of the bracket, the forearm is placed on the hand placing supporting plate, the first end of the steel wire rope is dragged, after being subjected to direction change by the crown block, the force is transmitted to the tension sensor on the second end of the steel wire rope, then the muscle strength of the musculus biceps brachii is detected, and thus the blank of the devicefor detecting the muscle strength of the musculus biceps brachii in the prior art is filled up.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a device for detecting the maximum muscle strength of biceps brachii. Background technique [0002] The biceps brachii is located on the front of the upper arm and has a fusiform shape. The biceps brachii has long and short biceps, hence the name. [0003] The long head originates from the superior glenoid tuberosity of the scapula, the short head originates from the coracoid process of the scapula, and the short head converges in the middle of the humerus to form a muscle belly, descends to the lower end of the humerus, and the integrated tendon inserts on the radial tuberosity and the fascia of the forearm. At near fixation, the biceps brachii flexes and externally rotates the forearm at the elbow joint, flexing the upper arm at the shoulder joint; at far fixation, the biceps brachii moves the upper arm closer to the anterior arm. Action: Bend shoulders, elbows, a...
