Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of clamps, and in particular to a neurological examination clamp. Background Technology
[0002] As a core functional component of electromyography, nerve conduction velocity detection, and tremor analysis systems, neurological examination clamps ensure high-fidelity acquisition of bioelectrical signals by stabilizing and fixing electrodes to the examination site. Their applications cover clinical and research scenarios such as diagnosis of neuromuscular diseases (e.g., amyotrophic lateral sclerosis), assessment of motor dysfunction, and monitoring of the efficacy of neurorehabilitation.
[0003] Taking electromyography (EMG) as an example, the clamp maintains stable contact between the electrode and the skin interface, ensuring accurate recording of muscle action potentials (MAP) and motor unit potentials (MUAP), providing key electrophysiological evidence for locating nerve damage (such as peripheral nerve entrapment) or differentiating myogenic / neurogenic lesions.
[0004] Currently, traditional clamps rely on a fixed pressure mode and usually cannot dynamically adjust the clamping force according to the patient's biomechanical characteristics (such as subcutaneous fat thickness and muscle tone level). When conducting long-term tests (such as for epilepsy patients), obese patients are prone to compressive discomfort. Utility Model Content
[0005] This utility model aims to at least partially solve one of the technical problems in the related art.
[0006] Therefore, one objective of this invention is to provide a neurological examination clamp that can achieve dynamic adaptive adjustment of clamp pressure, accurately adapt to the individualized surface characteristics of the patient, thereby significantly improving the comfort and safety of the examination process.

Each clamp includes a clamping portion and a force-applying portion, which are respectively disposed on opposite sides of the connecting assembly. The pressure sensor is embedded in the inner wall of one of the clamps. The pressure regulating assembly is connected to the force-applying portions of both clamps. The controller is disposed on the clamps and is connected to both the pressure sensor and the pressure regulating assembly.
[0008] In addition, the neurological examination clamp proposed above may also have the following additional technical features:
[0009] Specifically, the pressure regulating assembly includes two connecting rods and a driving member, wherein the force-applying part of the clamping plate is provided with two fixing plates; the two connecting rods are respectively disposed between the two corresponding fixing plates; the two ends of the driving member are respectively hinged to the two connecting rods, and the driving member is connected to the controller.
[0010] Specifically, the connecting assembly includes a support shaft and a torsion spring, wherein two support lugs are respectively provided on the opposite surfaces of the two clamping plates, and the support shaft is rotatably connected to the support lugs; the torsion spring is sleeved on the support shaft.
[0011] Specifically, the inner sidewall of the clamp is provided with electrodes, which are connected to the device via conductive wires.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
[0014] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which:
[0015] Figure 1 This is a schematic diagram of the structure of a neurological examination clamp according to an embodiment of the present invention;
[0016] Figure 2 This is a front view of a neurological examination clamp according to an embodiment of the present invention.

Electrode; 21. Supporting shaft; 22. Torsion spring; 41. Connecting rod; 42. Driving component. Detailed Implementation
[0018] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0019] The neurological examination clamp of this utility model embodiment will now be described with reference to the accompanying drawings.
[0020] like Figures 1 to 2 As shown, the neurological examination clamp of this utility model embodiment may include two clamps 1, a connecting assembly 2, a pressure sensor 3, a pressure regulating assembly 4, and a controller 5.
[0021] Two clamping plates 1 are arranged opposite each other and connected by a connecting component 2. Each clamping plate 1 includes a clamping part and a force-applying part, which are respectively arranged on both sides of the connecting component 2.
[0022] It should be noted that the splint 1 has an arc-shaped structure, and when the two splints 1 are closed, one end of the two splints 1 fits together, and the two clamping parts form a relatively closed space, which can clamp the patient's hand or leg.
[0023] Pressure sensor 3 is embedded in the inner wall of one of the clamping plates 1; pressure regulating component 4 is connected to the force-applying parts of both clamping plates 1 respectively; controller 5 is set on clamping plate 1 and is connected to pressure sensor 3 and pressure regulating component 4 respectively.
[0024] It should be noted that the pressure sensor 3 described in this embodiment can detect the pressure on the patient in real time and transmit the pressure data to the controller 5. The controller 5 analyzes the received pressure data and adjusts the pressure regulating component 4 according to the analysis results to avoid excessive pressure on the splint and compression of the patient during long-term examinations.
[0025] In one embodiment of this utility model, such as Figure 1 As shown, the pressure regulating assembly 4 includes two connecting rods 41 and a driving member 42. The force-applying part of the clamping plate 1 is provided with two fixing plates 6. The two connecting rods 41 are respectively disposed between the corresponding two fixing plates 6. The two ends of the driving member 42 are respectively hinged to the two connecting rods 41, and the driving member 42 is connected to the controller 5.
[0026] It should be noted that the driving component 42 described in this embodiment can be an electric push rod. The electric push rod can adjust the angle between the two clamps 1 to avoid excessive pressure on the clamps 1 and causing pressure on the patient.
[0027] Specifically, when the pressure detected by the pressure sensor 3 exceeds the pressure threshold (the pressure threshold can be set according to the actual situation and input into the controller 5 in advance), the controller 5 controls the telescopic rod of the drive component 42 to retract, so that the clamping gap between the clamps 1 is increased, thereby reducing the pressure applied to the patient and greatly improving the patient's comfort during long-term testing.
[0028] In one embodiment of this utility model, such as Figure 1As shown, the connecting assembly 2 includes a support shaft 21 and a torsion spring 22. The two clamping plates 1 are respectively provided with two support ear plates 7 on their opposite sides. The support shaft 21 is rotatably connected to the support ear plates 7. The torsion spring 22 is sleeved on the support shaft 21.
[0029] It should be noted that the two clamping plates 1 can rotate around the support shaft 21, and the two ends of the torsion spring 22 are respectively attached to the support ear plate 7.
[0030] In one embodiment of this utility model, such as Figure 1 As shown, the inner sidewall of the clamping plate 1 is provided with an electrode 8, which is connected to the equipment through a lead wire.
[0031] It should be noted that electrode 8 is usually made of silver / silver chloride. Electrode 8 is attached to the skin surface to record the overall electrical activity of a large range of muscle groups and transmits the detection results to the electromyography analysis device through the lead wire.
[0032] In one embodiment of this utility model, such as Figure 1 As shown, the two clamps 1 are provided with flexible protective layers on their opposite sides. The flexible protective layers can be made of rubber or silicone. The flexible protective layers have a certain degree of elasticity, making them more comfortable when in contact with the patient's skin, and they also have a certain degree of anti-slip effect.
[0033] Specifically, during a neurological examination, personnel clamp the splint 1 onto the patient's testing area and activate the testing equipment. If the patient is large, the splint 1 applies significant pressure. In this case, the pressure sensor 3 transmits the detected pressure data to the controller 5. The controller 5 then controls the telescopic rod of the drive component 42 to retract based on the pressure data, widening the clamping gap between the two splints 1 and thus reducing the pressure applied to the patient. This significantly improves patient comfort during prolonged testing.
[0034] In summary, the neurological examination clamp of this utility model embodiment can achieve dynamic adaptive adjustment of clamp pressure, accurately adapt to the individualized surface characteristics of the patient, thereby significantly improving the comfort and safety during the examination process.
