Technical Field
[0001] This invention belongs to the field of medical device technology, specifically relating to a device and method for monitoring nerve conduction function. Background Technology
[0002] Diabetes mellitus is a common endocrine and metabolic disease, and peripheral neuropathy is its most common and complex complication. This is due to nerve damage caused by the chronic hyperglycemic state and various pathophysiological changes resulting from diabetes, affecting more than 50% of diabetic patients. Symptoms of diabetic peripheral neuropathy include symmetrical pain and sensory abnormalities, with lower limb symptoms more common than upper limb symptoms. The most serious complication is diabetic foot. Diabetic peripheral neuropathy has a high prevalence and disability rate, severely impacting patients' quality of life. However, diabetic peripheral neuropathy often has an insidious onset and slow progression, and many patients do not present with obvious clinical manifestations, making it easy to miss the diagnosis. Therefore, early diagnosis and screening for peripheral neuropathy in diabetic patients are crucial. Currently, early diagnosis of diabetes in clinical practice often relies on manual methods or simple instruments to assess the patient's temperature sensation, pain sensation, light touch sensation, vibration sensation, joint position sense, ankle reflex, and knee reflex. While these methods are simple, they are subjective, with low precision and accuracy, and poor interpretability and repeatability.
[0003] Currently, nerve conduction function testing is considered the most objective, sensitive, and reliable method for diagnosing early diabetic peripheral neuropathy. Early diabetic peripheral neuropathy causes changes in nerve conduction function; by measuring nerve conduction function (e.g., nerve conduction velocity), the ability of peripheral nerves to transmit electrical signals can be assessed. Routine nerve conduction function tests typically include motor function assessment of the median, ulnar, common peroneal, and tibial nerves, as well as sensory function assessment of the median, ulnar, grid, and sural nerves. The results of these nerve measurements can reflect the presence, distribution, and severity of diabetic peripheral neuropathy. Nerve conduction velocity testing is sensitive, non-invasive, and reliable for diagnosing diabetic neuropathy, often detecting abnormalities in the early stages of diabetes. Therefore, nerve conduction velocity testing is an important diagnostic method for diabetic neuropathy, improving the diagnostic rate and detecting subclinical lesions.
[0004] Nerve conduction testing reflects the conduction process of impulses along nerve trunks, studying the functional state of the dorsal root ganglion and its posterior peripheral nerves. Electrical stimulation is applied to the first position of the nerve being examined; upon stimulation, the nerve exhibits excitability and conductivity. This conduction has a specific directionality; sensory nerve fibers transmit impulses towards the central nervous system, i.e., centripetal conduction. Utilizing this characteristic, pulsed current stimulation of sensory nerves is applied to measure nerve conduction velocity and amplitude to determine nerve conduction function, thereby assisting in the diagnosis of the presence and location of peripheral nerve lesions. However, currently available devices for monitoring nerve conduction function are not only inconvenient to install and have poor installation strength, but also can only perform simple monitoring of nerve function and cannot stimulate and restore damaged nerves. Therefore, we propose a device for monitoring nerve conduction function. Summary of the Invention
[0005] To address the problems mentioned in the background section, this invention provides a device and method for monitoring nerve conduction function.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for monitoring nerve conduction function, comprising: a mounting plate, a fastening assembly, and a monitoring assembly, wherein the fastening assembly and the monitoring assembly are both fixed to the surface of the mounting plate;

[0016] A monitoring method for a device for monitoring nerve conduction function includes the following steps:
[0017] Step 1: Detect the monitoring area using the ultrasonic detection module to obtain the approximate nerve distribution in the monitoring area. Then, select the monitoring nerve and set the nerve adjacent to the monitoring nerve as the comparison nerve. Fix the device to the surface of the monitoring nerve using the fastening assembly.

[0019] Step 3: Stimulate the monitoring nerve and the control nerve multiple times using the stimulation electrodes. Monitor all stimulation signals emitted by the stimulation electrodes using the detection electrodes and record the feedback values. The recorded values for the control nerve are the standard values, and the recorded values for the monitoring nerve are the weakened values. The difference between the two is the damage value of the monitoring nerve.
[0020] Step 4: Set the standard value to 1. When the damage value is 0-0.4, the monitored nerve is weakly damaged, the stimulation time of the stimulation electrode is 5-10 min, the single stimulation time is 50-200 μs, and the stimulation current intensity is 0-0.4 mA; when the damage value is 0.4-0.7, the monitored nerve is moderately damaged, the stimulation time of the stimulation electrode is 10-20 min, and the single stimulation time is 300-650 μs; when the damage value is 0.7-1, the monitored nerve is severely damaged, the stimulation time of the stimulation electrode is 20-40 min, and the single stimulation time is 800-1400 μs.

There are several detection electrodes 320 and stimulation electrodes 310, and the number is the same. The detection electrodes 320 and the stimulation unit are both set at one end of the vibration unit 130, and the stimulation unit and the detection unit are arranged opposite to each other. In this device and method for monitoring nerve conduction function, the high-frequency sound waves emitted by the ultrasound detection module can pass through nerve tissue. When the ultrasound passes through the tissue, the sound waves will be reflected, scattered, and absorbed. These characteristics of the sound waves can be received by the ultrasound probe and converted into an image by the processing module 330, thereby detecting the nerve distribution in the area to be monitored, which makes it convenient for medical staff to fix the mounting plate 1 in the monitoring area.
[0041] Mounting plate 1 includes a vibration unit 130 fixed to the surface of mounting plate 1. The vibration unit 130 is connected to the processing module 330. There are several vibration units 130, which are evenly arranged on the surface of mounting plate 1. The vibration unit 130 includes a telescopic module 131 and a pressure sensing module, which are used to amplify and record the path and intensity of muscle tremors. By setting the telescopic module and the pressure sensing module, when the muscle tremors, the telescopic module that is in contact with the muscle can extend and retract in the vertical direction according to the muscle tremor, thereby giving the pressure sensing module at one end of the telescopic module an instantaneous pressure, which is recorded in the processing module. When the position of the muscle tremor changes continuously, the muscle tremor path can be formed in the processing module, so that the direction and speed of movement of the electrical stimulation emitted by the stimulation electrode in the nerve are realized.
[0042] Mounting plate 1 is composed of a rigid plate 110 and an elastic plate 120 connected together. The elastic plate 120 is fixed to the side of the rigid plate 110, and the fastening assembly 2 is also fixed to the side of the rigid plate 110. The vibration unit 130 is fixed to the surface of the rigid plate 110. A movable cavity 121 is formed inside the elastic plate 120. A rotating shaft 122 is fixed inside the movable cavity 121 by bearings. One end of the connecting belt 210 is fixed to the surface of the rotating shaft 122. A movable groove 123 is formed on the surface of the movable cavity 121, and the connecting belt 210 passes through the movable groove 123. Return springs are provided at both ends of the rotating shaft 122. The connecting strap 210 can be wound around the surface of the rotating shaft 122 by a return spring; the device and method for monitoring nerve conduction function, by setting the connecting strap 210, the connecting block 220 and the locking block 230, can fix the mounting plate 1 to the patient's body surface, so as to avoid the mounting plate 1 from detaching from the patient's body surface or shifting when detecting nerve function and stimulating the monitored nerve, which would lead to deviation in the detection results or reduced treatment effect. At the same time, with the elastic plate 120, the mounting plate 1 can fit against the human body surface, avoiding gaps between the mounting plate 1 and the human body.
[0043] A monitoring method for a device for monitoring nerve conduction function includes the following steps:
[0044] Step 1: Detect the monitoring area using the ultrasonic detection module to obtain the approximate nerve distribution in the monitoring area. Then, select the monitoring nerve and set the nerve adjacent to the monitoring nerve as the comparison nerve. Fix the device to the surface of the monitoring nerve using the fastening component 2.
[0045] This device and method for monitoring nerve conduction function can accurately determine whether the monitored nerve is damaged or inactive through multi-nerve comparative monitoring, and further compare the nerve data to determine the location of the damaged or inactive nerve. At the same time, it can also monitor the stimulation signal emitted by the stimulation electrode 310 through the detection electrode 320, record its feedback value, thereby obtaining the degree of damage to the monitored nerve, and perform corresponding stimulation treatment according to the degree of damage.
[0046] Step 2: The detection electrode 320 and the stimulation electrode 310 are placed at both ends of the monitoring nerve. The monitoring nerve is stimulated by the stimulation electrode 310 to induce muscle tremors. The muscle tremors are amplified by the tremor unit 130, and the tremor path and intensity are recorded by the processing module 330. Based on the muscle tremor path, it is determined whether the monitoring nerve is incomplete / inactive according to whether there is a break in the muscle tremor path, and the location of the incomplete / inactive monitoring nerve is determined according to the break point location. In Step 2, the stimulation electrode 310 and the detection electrode 320 are placed at both ends of the comparison nerve, and the comparison nerve is stimulated synchronously.
[0047] The device and method for monitoring nerve conduction function can amplify muscle tremors through multiple sorted tremor units 130, and record the tremor path and intensity through the processing module 330. It can accurately determine the distribution path of the monitoring nerve, and calculate the attenuation of the stimulus signal in the monitoring nerve based on the intensity of the muscle tremor. Furthermore, based on the muscle tremor path, it can determine whether the monitoring nerve is incomplete / inactive by whether there is a break in the muscle tremor path, and determine the location of the incomplete / inactive monitoring nerve based on the location of the break.
[0048] Step 3: The monitoring nerve and the control nerve are stimulated multiple times using the stimulation electrode 310. All stimulation signals emitted by the stimulation electrode 310 are monitored using the detection electrode 320, and the feedback values are recorded. The recorded value for the control nerve is the standard value, and the recorded value for the monitoring nerve is the attenuation value. The difference between the two is the damage value of the monitoring nerve. In Step 3, the feedback values recorded by the detection electrode 320 are current density and cellular Na+. + The inflow.
[0049] The device and method for monitoring nerve conduction function stimulates the monitored nerve with current through stimulation electrode 310. This not only increases nerve conduction speed, improves the signal transmission ability of damaged nerves, promotes blood circulation, and increases the supply of oxygen and nutrients, which helps nerve repair and regeneration, but also reduces pain and muscle spasms caused by nerve damage, improving patient comfort. At the same time, the current stimulation can activate healthy nerves around the damaged nerves, promote their functional recovery, and improve the patient's motor and sensory functions.
[0050] Step 4: Set the standard value to 1. When the damage value is 0-0.4, the monitored nerve is weakly damaged, the stimulation time of the stimulation electrode 310 is 5-10 min, the single stimulation time is 50-200 μs, and the stimulation current intensity is 0-0.4 mA; when the damage value is 0.4-0.7, the monitored nerve is moderately damaged, the stimulation time of the stimulation electrode 310 is 10-20 min, and the single stimulation time is 300-650 μs; when the damage value is 0.7-1, the monitored nerve is severely damaged, the stimulation time of the stimulation electrode 310 is 20-40 min, and the single stimulation time is 800-1400 μs.
[0051] This device and method for monitoring nerve conduction function classifies the monitored nerves into different degrees of damage, enabling the stimulation electrode 310 to provide precise stimulation treatment. This avoids further nerve damage caused by stimulation time, intensity, and frequency exceeding the tolerance limit. At the same time, the current stimulation emitted by the stimulation electrode 310 can promote the regeneration and growth of nerve cells and accelerate the repair speed of damaged nerves.
[0052] Meanwhile, the low-intensity current stimulation emitted by the stimulation electrode 310 can not only promote cell regeneration and repair, improve cell metabolic activity and immune function, increase the uptake of oxygen and nutrients in cells, accelerate the excretion of waste, and enhance cell metabolic activity, but also increase cell membrane permeability, strengthen intercellular ion exchange, thereby promoting intercellular signal transmission and coordination. At the same time, it can inhibit the release of inflammatory mediators, reduce inflammatory responses in cells and tissues, thereby alleviating pain and discomfort, helping to maintain and restore normal cell function, and promoting physical health and recovery.

[0055] Step 1: Install the magnetic field sensor: Install the magnetic field sensor at a certain distance from the stimulation electrode 310 and the detection electrode 320; the position and orientation of the sensor should be selected according to the specific measurement requirements.
[0056] Step 2, Calibrate the sensor: Before performing the measurement, the magnetic field sensor is calibrated to ensure the accuracy of the measurement. The calibration method is to compare it with a standard sample with a known current density.
[0057] Step 3: Measure the magnetic field strength: Turn on the measuring instrument, connect the sensor to the instrument, and place the sensor at a certain distance from the stimulation electrode 310 and the detection electrode 320;
[0058] Step 4: Calculate the current density: Based on the relationship between the magnetic field measurement results and the magnetic field generated by the current, the current density can be calculated. The calculation method depends on the geometry of the current path and the position and orientation of the magnetic field sensor.
[0059] Step 5: Data Recording: Record the measured magnetic field strength and calculated current density, and perform data analysis.
[0060] Example 3
[0061] Based on Example 1, the present invention provides a method for detecting cellular Na+. + The method of inflow includes the following steps:
[0062] Step 1: Set up the voltage clamp system: Connect the electrodes to the voltage clamp amplifier and calibrate the electrodes; at the same time, set the parameters of the voltage clamp amplifier, such as the sampling frequency and the filter.
[0063] Step 2, Intracellular Recording: Insert the electrode into the cell membrane, ensuring close contact between the electrode and the cell membrane; adjust the voltage clamp amplifier using the control software to ensure accurate current signal recording within the cell.
[0064] Step 3, Apply stimulation: Induce the influx of Na+ into cells through stimulation methods such as voltage pulses or chemical substances;
[0065] Step 4: Record current changes: Record current changes on the cell membrane using a voltage clamp system; the influx of Na+ into the cell causes current changes, which can be converted into voltage signals by a voltage clamp amplifier and recorded and analyzed by control software.
[0066] Step 5: Data Analysis: Analyzing the recorded current signals can yield relevant information about the influx of Na+ into the cell, such as the influx rate and amplitude.
[0067] The working principle of this invention is as follows:
[0068] First, the area to be monitored is detected by ultrasound using the ultrasound detection module, thereby identifying the nerve distribution in the monitored area and determining the monitored nerve. Then, the device is attached to the location of the monitored nerve. Medical staff then pull the locking block 230, which is engaged in the groove 221, and push the fixing piece 222 to fix it in place, thereby fixing the mounting plate 1 in the monitored area.
[0069] Then, medical staff apply electrical stimulation to the monitoring nerve and the control nerve through the stimulation electrode 310. The electrical stimulation causes the muscles on the surface of the nerve to tremble. Subsequently, the tremor unit 130 attached to the surface of the muscle amplifies the muscle tremor and records the tremor path and intensity through the processing module 330. Based on the muscle tremor path, it is determined whether the monitoring nerve is damaged / inactive according to whether there is a break in the muscle tremor path, and the location of the damaged / inactive monitoring nerve is determined according to the location of the break.
[0070] Finally, the monitoring nerve and the control nerve are stimulated multiple times by the stimulation electrode 310, and all stimulation signals emitted by the stimulation electrode 310 are monitored by the detection electrode 320 and their feedback values are recorded to determine the degree of damage to the monitoring nerve and to stimulate the damaged nerve for recovery.
