Description

Technical Field

[0001] The utility model relates to the technical field of information collection, in particular to a sports injury information collection and diagnosis device based on sEMG technology. Background Art

[0002] Research has found that once skeletal muscle is injured, it takes a long time to heal, the quality of healing is unreliable, and it is easy to form hematomas and repair scars. The lack of elasticity of scar tissue can easily cause muscle stiffness and atrophy, affecting the functional recovery of the patient's muscles and seriously affecting the effect of information collection. The prevention of skeletal muscle injuries and early rapid and accurate diagnosis, as well as targeted treatment and rapid rehabilitation plans, play a very important role in reducing the incidence of sports injuries.

[0003] For patients with skeletal muscle injury, outpatient and emergency departments often use electromyography (EMG) to reflect the degree and prognosis of acute and chronic skeletal muscle injury. Traditional EMG is affected by many factors, and the probe needs to be inserted into the body, which is an invasive operation. In addition, electromyographic signals are easily affected by adjacent muscles, environment, and noise, and only changes in electromyographic signals can be observed, and morphological information after muscle injury cannot be obtained.

[0004] Surface electromyography (sEMG) can objectively reflect the physiological status of skeletal muscle and nervous system. By obtaining useful information from surface electromyography signals and quantifying this information, it can objectively and effectively reflect the damage status of skeletal muscle. Surface electromyography signals are the changes in human electrical signals when the neuromuscular system is performing voluntary and involuntary activities. After being amplified, displayed and recorded by surface electrodes, the obtained result is a voltage time series signal, which is an important method for non-invasive detection of muscle activity on the body surface. The electromyogram detected by surface electromyography signals is a waveform diagram that reflects the bioelectric activity law of the muscle nervous system and records the electrical effect of muscle contraction. Since the amplitude of sEMG electrical signals is very weak, the amplitude is generally several hundred microvolts, the average value can reach up to about 1mV, and the generation of surface electromyography action potentials is highly random and belongs to random non-stationary signals, so this technology has good safety. It has been successfully applied in disciplines such as orthopedics, neurosurgery and rehabilitation physiotherapy, and is currently a hot research at home and abroad.

[0005] The current wearable vital signs monitoring equipment mainly collects common indicators such as blood pressure and heart rate, but lacks specific rapid diagnosis and preparation for skeletal muscle injuries. Therefore, if skeletal muscle injury diagnosis equipment based on sEMG technology can be developed, it will effectively improve the ability of grassroots health units to quickly and accurately diagnose information and collect skeletal muscle injuries. Utility Model Content

[0006] The utility model aims to provide a sports injury information collection and diagnosis device based on sEMG technology to solve the problem in the prior art that primary health units cannot quickly and accurately diagnose information collection of skeletal muscle injuries.

The electrode sheet can transmit the collected surface electromyography signals to the signal processor in real time. The signal processor converts the collected signals into key indicators for the athlete's sports injury assessment and transmits them to the control chip, which transmits them to the terminal through the wireless communication device. The terminal monitors the key indicators collected by the device in real time and evaluates and judges the thresholds of the key indicators. When the key indicators exceed the thresholds, the terminal system feeds back the evaluation results to the signal processor through the wireless communication device and the control chip. The signal processor can control the indicator light to flash to remind athletes that their training volume is overloaded, thereby achieving early rapid and accurate diagnosis and reminder of skeletal muscle injury. At the same time, according to the flashing indicator light, the remote mobilizer can quickly and specifically give a rapid recovery plan, press the corresponding microneedle drug delivery component, and administer the drug to the athlete's subcutaneous tissue. Timely drug injection can effectively reduce the incidence of sports injuries. At the same time, the microneedle drug delivery component is detachably connected to facilitate timely replacement of the microneedle drug solution. Secondly, the fixed component is connected to the breathable chamber, which can increase the breathability of the device and effectively prevent sweat from interfering with the monitoring data of the electrode.

At the same time, the telescopic rod is shortened and the spring 1 is in a compressed state. The downward moving support plate 1 drives the microneedle to move downward and penetrate into the subcutaneous tissue in use. The puncture component is pressed or rotated to make the puncture component pierce the baffle plate, so that the corresponding muscle analgesic medicine (muscle analgesic medicine is flurbiprofen, lornoxicam, parecoxib, ketorolac tromethamine, butapatamol) in the microneedle flows into the subcutaneous tissue along the needle hole. After the injection of the medicine, the spring button component is pressed again, and the spring button component moves upward to recover, releasing the restriction on the support plate 1. The support plate 1 moves upward under the recovery elastic force of the spring 1, driving the microneedle to move upward and leave the subcutaneous tissue in use, thereby completing the injection of the medicine.
