Design and application of a new magnetic joint for electroacupuncture instrument

Combined with the material characteristics of acupuncture needle, new connection technology and injection moulding technology, and through mechanical test, a new type of magnetic joint for electroacupuncture instrument, with regular appearance and simple manufacturing process, is developed, which can be connected with acupuncture needle in close range. This joint is composed of the inner magnet joint and the outer joint protective sleeve. The new conductive adhesive is used to simplify the manufacturing process. Its advantages include connection with acupuncture needle by magnetic force, being convenient to store when idle and easy to switch to the working state, and quick disconnection in case of emergency. This joint is connected safely and firmly with acupuncture needle by magnetic force, which shortens the operation time, improves the working efficiency, and effectively solves the problems existing in the crocodile clip connector.
