Abstract
The invention relates to a flexible paste electric stimulator, which comprises a flexible circuit board containing an electric stimulation circuit and a flexible insulation protection device which is used for sealing and fixing the flexible circuit board. The thickness of the flexible insulation protection device is no larger than 5mm, a face on the outer side of the insulation protection device serves as an attaching face to a human body, and two electrode lead-out holes of the electric stimulation circuit are positioned on the attaching face of the insulation protection device. The flexible paste electric stimulator is simple in structure, small in thickness of the electric stimulator and convenient to wear for patients. Due to flexibility of the electric stimulator, the appearance can change along with the shapes of wearing portions, muscles and bones cannot be uncomfortable, and patients feel comfortable when wearing the flexible paste electric stimulator. Simultaneously, tie belts are eliminated due to the fact that the electric stimulator can be directly attached to skins or attached to skins through adhesion tapes, and a plurality of electric stimulators can be conveniently to be worn on different parts of patients.
