Nerve and muscle stimulator

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a nerve and muscle stimulator.

Background

Neuromuscular stimulators (Neuromuscular Electrical Stimulation, NMES) are medical devices that produce therapeutic effects by stimulating nerves and muscles with electrical current. It can be used for rehabilitation, muscle function recovery, pain management, etc. Neuromuscular stimulators typically consist of one or more electrodes and a controller. The electrodes pass electrical current through the nerves and muscle tissue of the body by sticking or placing on the skin. The controller can set the intensity, frequency and duration of the current to achieve therapeutic objectives.

However, most of the existing neuromuscular stimulators are provided with electrode patches on two sides of a controller, the lower part of the controller is not covered by the electrode patches, the coverage area of the electrode patches is smaller, and the nerve and the muscle tissues below the controller cannot be subjected to micro-electrical stimulation.

We have therefore proposed a nerve and muscle stimulator in order to solve the problems presented above.
