Abstract

The present invention relates to the field of wearable neurotherapy devices, and particularly relates to a wrist-worn nerve stimulator. The nerve stimulator is suitable for the wrist and other parts of limbs. For the nerve stimulator, a conducting medium attached to a strap not only ensures no tingling sensation during electrical stimulation therapy, but also alleviates the problem of discomfort without prejudice to the therapeutic effect, thereby reducing the difficulty of assembling the nerve stimulator and improving wearing adaptability; in addition, it can be seen from the use of a first strap and an electrical stimulation part that the wrist-worn nerve stimulator has a split structure and is composed of the first strap and the electrical stimulation part, such that the difficulty of disassembling basic frameworks for electrical stimulation therapy is significantly reduced, and it can be understood that the consumable first strap is easier to be replaced.

Dependent claims

A wrist-worn nerve stimulator, comprising an electrical stimulation part and a first strap, wherein after the first strap is worn on the wrist, the electrical stimulation part is superimposed on the first strap to keep an output end of the electrical stimulation part contactable with a conducting medium on the first strap, the conducting medium is solid-state, at least two surfaces of the conducting medium are exposed outside a constraint of the first strap on the conducting medium, one surface of the conducting medium is pasted on a surface of the wrist during wearing process, and an output end of the electrical stimulation part is in contact with the other surface of the conducting medium;

wherein a second strap that can be worn on the wrist is arranged on a side surface of the electrical stimulation part, the output end of the electrical stimulation part has a split structure, and comprises a plurality of conduction plates arranged on an inner surface of the second strap and constitute a circuit, and a plurality of first conductive components installed on the first strap and connected with the conducting medium;
the second strap surrounds the first strap, and the conduction plates corresponds to the respective first conductive components;
during electrical stimulation therapy, a current from the electrical stimulation part sequentially passes through the corresponding conduction plate, the first conductive component and the conducting medium, and then enters the wrist.
