Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a lower limb muscle tension detection device. Background Technology

[0002] Parkinson's disease is a neurological disorder that primarily affects middle-aged and elderly individuals. Its main pathological features include significant loss of dopaminergic neurons and the formation of cytoplasmic inclusion bodies (Lewy bodies) containing α-synuclein. Parkinson's patients often exhibit symptoms such as resting tremor, rigidity, bradykinesia, and postural and gait disturbances. Rigidity is one of the most important clinical manifestations of Parkinson's disease. Measuring lower limb muscle tone helps assess the severity of symptoms and treatment effectiveness. Currently, the primary device used to measure lower limb muscle tone in Parkinson's patients is an electromyography (EMG) machine, which works by attaching an EMG device to the patient's lower limbs. After the electrodes are applied, muscle activity data can be collected when the patient walks or performs specific movements. The electromyography (EMG) machine can then generate an EMG to assess the patient's muscle tension. However, in current EMG machines, the electrodes are connected to the main body of the machine, which prevents the patient from walking freely or performing the specified movements, affecting the acquisition of EMG data. In addition, when the electrodes are attached to the patient's lower limbs, they may fall off or become loose as the patient moves, leading to inaccurate data acquisition. However, current EMG equipment cannot detect whether the electrodes are properly attached and provide any alerts. Utility Model Content

[0003] Therefore, this utility model proposes a lower limb muscle tension detection device that can be worn on the patient for easy movement. At the same time, if the electrode patch falls off, the indicator light will dim to provide a warning, thus avoiding inaccurate data collection.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A lower limb muscle tension detection device includes an elastic band, a mounting box, a transmission plug, and a data acquisition mechanism. The mounting box is symmetrically arranged on the outer wall of the elastic band, and the transmission plug is located on the top surface of the mounting box. The data acquisition mechanism includes a winding drum, a winding mechanism, a data cable, electrode patches, a normally open button, an indicator light, a battery pack, and a main control unit. The winding drum is rotatably disposed within the mounting box, and the winding mechanism drives the winding drum to rotate. The data cable is wound around the winding drum, with its bottom end extending below the mounting box. The electrode patches are electrically connected to the data cable. The normally open button is disposed on the electrode patch. The indicator light is located on the outer wall of the mounting box, above the electrode patch. The battery pack is disposed within the mounting box. The normally open button on the same electrode patch and the indicator light above it form a series circuit, and the battery pack and the series circuit form a loop. The main control unit is disposed within the mounting box and is electrically connected to the transmission plug, the winding mechanism, and the data cable.

[0006] Preferably, the data acquisition mechanism further includes an adhesive layer and a release paper. The adhesive layer is disposed on the side wall of the electrode patch, the normally open button passes through the adhesive layer, and the release paper is disposed on the adhesive layer.

[0007] Preferably, the winding mechanism includes a motor and side plates, the side plates are disposed opposite each other on the top surface of the mounting box, the winding drum is located between the side plates, the motor is disposed on the side wall of the side plate, its output shaft passes through the side wall of the side plate and is connected to the end of the winding drum, and the main control unit is electrically connected to the motor.

[0008] Preferably, the data acquisition mechanism further includes a conductive head and a conductive sheet. A groove is provided on the side wall of the side plate away from the motor. The conductive sheet is located in the groove. One end of the conductive head is located at the end of the take-up drum, and the other end extends into the groove and contacts the conductive sheet.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] ① The device uses a split-body detection method. It can be fixed to the patient's lower limb with an elastic band. Then, pulling the electrode patch stretches the data line and attaches the electrode patch to the patient's lower limb. The patient can carry the entire detection device to walk and perform specified actions. The data collected by the electrode patch is transmitted to the main control unit through the data line and stored by the main control unit. After the data collection is completed, it can be connected to the electromyography machine through the transmission plug to realize data transmission, thereby enabling the detection of muscle tension in the patient's lower limb.

[0013] ② A normally open button is installed on the electrode patch. When the electrode patch is attached to the patient's skin, the normally open button will be closed, and the power from the battery pack can be transmitted to the indicator light. During data acquisition, if part of the electrode patch falls off, the normally open button will be removed from the patient's skin and return to the open state, cutting off the circuit. At this time, the indicator light will dim, thus alerting the patient or medical staff that the electrode patch has fallen off, avoiding the problem of inaccurate electromyography data.

[0020] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] See Figures 1 to 4 This utility model provides a lower limb muscle tension detection device, including an elastic band 1, a mounting box 2, a transmission plug 3, and a data acquisition mechanism. The mounting box 2 is symmetrically arranged on the outer wall of the elastic band 1, and the transmission plug 3 is arranged on the side wall of the mounting box 2. The data acquisition mechanism includes a winding drum 4, a winding mechanism, a data cable 5, electrode patches 6, a normally open button 7, an indicator light 8, a battery pack 9, and a main control unit 10. The winding drum 4 is rotatably disposed inside the mounting box 2, and the winding mechanism drives the winding drum 4 to rotate. The data cable 5 is wound around the winding drum. The bottom end of the tube 4 extends below the mounting box 2. The electrode patch 6 is electrically connected to the data cable 5. The normally open button 7 is located on the electrode patch 6. The indicator light 8 is located on the outer wall of the mounting box 2 and above the electrode patch 6. The battery pack 9 is located in the mounting box 2. The normally open button 7 on the same electrode patch 6 and the indicator light 8 above it form a series circuit 11. The battery pack 9 and the series circuit 11 form a loop. The main control unit 10 is located in the mounting box 2 and is electrically connected to the transmission plug 3, the winding mechanism and the data cable 5 respectively.

[0022] A corresponding mounting box 2 is provided on the outer wall of the elastic band 1. The elastic band 1 can be fixed on the lower limbs of Parkinson's patients and is suitable for patients of different body types. When performing muscle tension testing, the outer electrode patch 6 can be pulled to the designated position and then pasted on the patient's skin. One end of the electrode patch 6 is connected to the data cable 5, which is wound on the winding drum 4. Therefore, the winding drum 4 can be pulled to rotate. After the electrode patch 6 is pasted, the patient can walk freely and complete the designated movements. During the patient's movements, the electrode patch 6 can collect electromyographic data and transmit the data. The data cable 5 is transmitted to the main control unit 10 for storage. After the data acquisition is completed, the electrode patch 6 can be removed from the patient. Then, the winding mechanism drives the winding drum 4 to rotate, so that the data cable 5 can be stored. After winding, the transmission plug 3 can be connected to the electromyography machine to transmit the electromyographic data to the electromyography machine for lower limb muscle tension detection. Since the detection device and the electromyography machine adopt a separate structure, the patient can walk freely and quickly complete the specified movements, which improves the efficiency of data acquisition. At the same time, it can avoid the situation where the collected data cannot accurately assess the muscle tension due to the patient's restriction.

[0023] Indicator lights 8 are installed on the outer wall of the mounting box 2. The number of indicator lights 8 is the same as the number of electrode patches 6, and each indicator light 8 is located above each electrode patch 6. Four normally open buttons 7 are installed on the outer wall of the electrode patch 6. When the electrode patch 6 is attached to the patient's lower limb, all normally open buttons 7 are triggered to the closed state. At this time, the normally open buttons 7 are connected to the series circuit 11 where the indicator lights 8 are located, and the power of the battery pack 9 can be transmitted to the indicator lights 8, which will light up. During the data acquisition process, if part of the electrode patch 6 is detached due to the patient's improper movement, the normally open buttons 7 will leave the patient's skin and return to the open state. At this time, the series circuit 11 is cut off, and the indicator lights 8 dim, which is used to indicate to the patient or medical staff that the electrode patch 6 has been detached, so that the electrode patch 6 can be fixed in time to avoid inaccurate electromyography data due to poor adhesion.

[0024] Preferably, the data acquisition mechanism further includes an adhesive layer 12 and a release paper 13. The adhesive layer 12 is disposed on the side wall of the electrode patch 6, the normally open button 7 passes through the adhesive layer 12, and the release paper 13 is disposed on the adhesive layer 12.

[0025] The release paper 13 is used to protect the adhesive layer 12. When testing is required, the release paper 13 can be removed, and then the adhesive layer 12 can be attached to the patient's lower limb skin. Since the normally open button 7 passes through the adhesive layer 12, it will be pressed into a closed state when the adhesive is applied.

[0026] Preferably, the winding mechanism includes a motor 14 and side plates 15. The side plates 15 are disposed opposite each other on the top surface of the mounting box 2. The winding drum 4 is located between the side plates 15. The motor 14 is disposed on the side wall of the side plate 15, and its output shaft passes through the side wall of the side plate 15 and is connected to the end of the winding drum 4. The main control unit 10 is electrically connected to the motor 14.

[0027] During testing, the data cable 5 can be pulled downwards to rotate the winding drum 4 and release the data cable 5. After testing is completed, the motor 14 can drive the winding drum 4 to rotate, so that the data cable 5 can be rewound onto the winding drum 4, thus realizing the storage of the data cable 5.

[0028] Preferably, the data acquisition mechanism further includes a conductive head 16 and a conductive sheet 17. A groove 18 is provided on the side wall of the side plate 15 away from the motor 14. The conductive sheet 17 is located in the groove 18. One end of the conductive head 16 is located at the end of the take-up drum 4, and the other end extends into the groove 18 and contacts the conductive sheet 17. The main control unit 10 is electrically connected to the conductive sheet 17. One end of the data cable 5 wound on the take-up drum 4 is electrically connected to the conductive head 16.

[0029] The data cable 5 is wound around the take-up drum 4, and its end is electrically connected to the conductive head 16. The conductive head 16 extends back into the groove 18 and is electrically connected to the conductive sheet 17. The data transmitted by the data cable 5 can be transmitted to the main control unit 10 through the conductive head 16 and the conductive sheet 17. Even if the take-up drum 4 rotates, the normal transmission of data can be guaranteed.

[0030] Preferably, the winding mechanism further includes a male plug 19, a female plug 20, and a wire 21. The male plug 19 is located on the end of the data cable 5 outside the mounting box 2. One end of the wire 21 is connected to the electrode patch 6, and the other end is connected to the female plug 20. The male plug 19 and the female plug 20 are detachably connected.

[0031] The data cable 5 and the electrode patch 6 are designed to be detachable. After the test is completed, the male plug 19 and the female plug 20 can be separated, so that the removed electrode patch 6 can be cleaned or disposed of properly, and then a new electrode patch 6 can be installed. The data collected by the electrode patch 6 can be transmitted from the wire 21, the female plug 20 and the male plug 19 to the data cable 5 and sent to the main control unit 10.

[0032] Preferably, the data acquisition mechanism further includes a trigger button 22, which is disposed on the outer surface of the male plug 19, and the main control unit 10 is electrically connected to the trigger button 22.

[0033] When the male plug 19 is inserted into the female plug 20, the trigger button 22 is triggered and sends an electrical signal to the main control unit 10. After the test is completed, the male plug 19 is pulled out of the female plug 20. At this time, the trigger button 22 is reset and stops sending electrical signals to the main control unit 10. The main control unit 10 determines that the test is completed, and then drives the motor 14 to drive the winding drum 4 to rotate, so as to realize the winding of the data cable 5.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
