Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a formulation for an electrode connection structure of a neuromuscular stimulator. Background Technology
[0002] With increasing awareness of health management and technological advancements, electrostimulation-based treatments are gaining more and more attention. Currently, most neuromuscular stimulation devices on the market use reusable electrode pads, typically composed of conductive gel and metal. While these pads have a long lifespan, they present challenges such as complex cleaning and maintenance, and a high risk of cross-infection. In recent years, to overcome these problems, disposable neuromuscular stimulation electrodes have gradually become a research hotspot. The development of these products not only improves the safety and hygiene standards of treatment but also simplifies the patient's experience and enhances the overall user experience.
[0003] Most disposable neuromuscular stimulation electrodes currently on the market use aluminum foil as the electrode material, which is then fixed to an insulating backing with adhesive. While this design can meet the needs of temporary use to some extent, it still reveals many limitations in practical applications. First, the relatively poor conductivity of aluminum foil leads to low energy transfer efficiency, thus affecting the treatment effect. Second, due to the lack of good sealing measures, prolonged wear can easily cause skin allergic reactions. Finally, the choice of a single material limits the adaptability to different treatment needs; for example, it is impossible to flexibly adjust the electrode impedance to match individual differences.
[0004] In summary, while existing disposable neuromuscular stimulation electrodes have improved in terms of convenience and safety, they still face problems such as poor conductivity, low comfort, and limited applicability, and there is an urgent need to find more advanced and reasonable alternatives.

[0010] Furthermore, the connector includes a metal pressure plate with a through hole. The positive and negative electrodes have through holes corresponding to the positions of the through holes. The through holes are fitted outside the positive and negative electrode interfaces. The metal pressure plate passes through the through holes and presses against the positive and negative electrodes.
[0011] Furthermore, the connector includes cables that are pressed onto the positive and negative electrodes, with the other end of the cable soldered to the positive and negative electrode interfaces.
[0012] Furthermore, the connector includes a 2P male connector bonded to the positive and negative electrodes, and a 2P female connector bonded to the upper PCBA board, with the 2P male connector mating with the 2P female connector.
