Description

Technical Field

[0001] The present invention relates to the technical field of electromyogram acquisition, and specifically to a wearable sensing device and system for electromyogram acquisition. Background Art

[0002] When a muscle contracts, a weak current is generated. Electrodes attached to appropriate positions on the skin can measure the current of the muscles on the body surface. The curve of the current intensity changing with time is called an electromyogram (EMG). An electromyogram uses electronic instruments to record the bioelectrical signals of muscles at rest or during contraction, and is often used in medicine to examine the excitability and conduction functions of nerves and muscles, etc., so as to determine the functional states of peripheral nerves, neurons, neuromuscular junctions, and muscles themselves. In 1985, Tornberg first applied electromyogram to the field of food science. Since then, electromyogram technology has been used for the measurement of food texture. This method is a relatively simple method for measuring muscle activity. Because the electrodes are attached to the skin, the potential changes of the muscles close to the skin surface can be measured, and normal chewing activities are not disturbed. By measuring the duration and amplitude of the motor unit potential, whether there is spontaneous electrical activity under quiet conditions, and the waveform and amplitude of the muscle during strong contraction, neurogenic damage and myogenic damage can be distinguished, and acute and chronic damage to the anterior horn of the spinal cord (such as poliomyelitis, motor neuron disease), nerve root and peripheral nerve lesions (for example, electromyogram examination can assist in determining the location, degree, scope, and prognosis of nerve injury) can be diagnosed. In addition, it also has diagnostic value for nerve entrapment lesions, neuritis, genetic metabolic disorder neuropathies, and various muscle diseases. In addition, electromyogram is also used to track the recovery process and curative effect of diseases during the treatment of various diseases; When the device is worn and used, it is usually fixed by sticking with Velcro. Since the Velcro is easily affected in its sticking effect after long-term use, the device is likely to fall off during wearing. At the same time, when the electrode patches are stuck to the muscles of the user, due to the different sticking heights of the electrode patches, the length of the wires used by the electrode patches is too long, making it easy to pile up and affecting the comfort of wearing the device. Summary of the Invention (I) Technical Problems to be Solved

[0003] In view of the deficiencies of the prior art, the present invention provides a wearable sensing device and system for electromyogram acquisition. One side of the fastening cloth belt penetrates through the inside of the clamping block. By using the elasticity of the first spring, it can push the extrusion plate to one side to extrude the first spring, so that the extrusion spike can penetrate through the inside of the fastening cloth belt. When the length of the fastening cloth belt is adjusted, the extrusion plate can drive the extrusion spike to reset by using the elasticity of the first spring, so that the extrusion spike can be inserted into the inside of the clamping block, and the fastening cloth belt can abut against the inner wall of the clamping block. The rear surface of the fastening cloth belt is adhered to the magic tape. Pull the second fixing plate forward, so that the second rubber pad can be separated from the first rubber pad. Pass one side of the fastening cloth belt through the space between the first rubber pad and the second rubber pad, and then release the second fixing plate. By using the elasticity of the second spring, it can pull the second fixing plate back to drive the second rubber pad to reset, so that the first rubber pad and the second rubber pad can clamp the fastening cloth belt, making the sensor more stable when worn. Before the electrode patch is used, the wires used for the electrode patch can be wound around the surface of the winding rod in opposite directions respectively. By sliding the moving plate, the distance between the two winding rods can be adjusted according to the length of the wire. By sliding the fixing rod, it can push the fixing rod to move. The wear-resistant pad can increase the friction between the fixing rod and the vertical plate and the mounting block, so that the fixing rod can fix the moving plate, making the winding length of the wire on the surface of the winding rod longer. After the wire is wound up, by using the elasticity of the third spring, one side of the pressing plate can be released, so that the pressing plate can rebound and press the wire on the surface of the winding rod for fixation, thus preventing the wire from being too long and affecting the comfort of the device when worn and other advantages.

[0015] 2. Before the electrode sheet is used in the present invention, the wires used for the electrode sheet can be wound around the surface of the winding rod in opposite directions respectively. By sliding the moving plate, the distance between the two winding rods can be adjusted according to the length of the wire. By sliding the fixing rod, the fixing rod can be pushed to move. The wear-resistant pad can increase the friction between the fixing rod and the vertical plate and the mounting block, so that the fixing rod can fix the moving plate, making the winding length of the wire on the surface of the winding rod longer. After the wire is wound up, due to the elasticity of the third spring, one side of the pressing plate can be released, and the pressing plate can rebound to press and fix the wire on the surface of the winding rod, thereby preventing the wire from being too long and affecting the comfort of wearing the device.
