Device for measuring skin muscle tension

Abstract

The invention discloses a device for measuring skin muscle tension. The device comprises a pressure sensor, a spring, a differential transformer, an internal upper supporting plate, an internal upper linear bearing, an internal lower linear bearing, a sealed bottom cover, a handheld outer cover, a measuring rod, a hand pressed handle and a pedestal, wherein the pressure sensor is used for measuring the pressure born by a muscle; the spring is used for restoring the primary position of the measuring rod; the differential transformer is used for measuring a compression displacement value of the muscle under the pressure; the internal upper supporting plate, the internal upper linear bearing, the internal lower linear bearing and the sealed bottom cover are used for ensuring that the measuring rod linearly moves; the measuring rod is used for applying a pressure value to the muscle; the hand pressed handle is used for applying an action force to the measuring rod; the pedestal is a standard of the moving displacement of the measured muscle under the action of the pressure; and the handheld outer cover is a frame of the device. The displacement value and the pressure value of the movement of the pressed muscle are measured through the differential transformer and the pressure sensor; and the tension degree of the muscle is measured quantitively according to the slope of a curve of the ratio of the pressure value to the displacement value.

Description

technical field [0001] The invention relates to a skin muscle tension measuring device, which is used to detect the tension degree and recovery condition of muscles after strenuous exercise or relaxation treatment such as massage. Background technique [0002] Muscle is an important part of the human body. Under the control of nerves, it can generate movement through its own active contraction, so as to realize the effect on the external environment and external objects. [0003] After a muscle receives an appropriate stimulus, it will contract once, and after a short contraction, it will relax immediately. The magnitude of the muscle contraction response depends on the intensity of the stimulus. The stimulus is too weak to elicit a response. As the stimulation intensity increases, the contraction response gradually increases. When the stimulation intensity exceeds the threshold, the muscle can only produce a weak response. [0004] When the muscle receives a second stimu...
