AI Technical Summary

Technical Problem

Existing fecal incontinence treatment systems cannot simultaneously cover multiple key target points in the perineal area. They suffer from poor electrode-skin contact, lack of dynamic adjustment capabilities, lack of synergistic stimulation, and weak sensor control linkage, resulting in poor treatment outcomes.

Method used

A fecal incontinence treatment system was designed, which uses a lotus seat stimulation unit and a medial malleolar tibial nerve module to work together. It includes an expandable bionic lotus seat structure and a dynamic sensing and control mechanism. Through multi-target synergistic electrical stimulation, it achieves precise coverage and synergistic stimulation of the perineal area and the medial malleolar tibial nerve.

Benefits of technology

It significantly improves the effectiveness of fecal incontinence treatment and patient compliance with home use, and solves the problems of single-target limitation, poor fit and inaccurate control of traditional devices.

Abstract

A fecal incontinence treatment system comprises a first module, a second module, a first sensing module and a second sensing module, the first module stimulates the nerve and muscle tissue of the perineal area through multi-target point synergistic electrical stimulation, the first module comprises a control unit and a lotus root stimulation unit, the control unit cooperates with the electrical stimulation of the second module according to the sensing signals obtained by the first sensing module and the second sensing module; four blades of the lotus root stimulation unit respectively contact the Changqiang acupoint, the perineal acupoint and the anal sphincter through the electrodes on the blades to perform electrical stimulation, and the columnar electrode of the lotus root stimulation unit contacts the pudendal nerve projection area to perform electrical stimulation; the second module is used for stimulating the superficial projection area of the medial calcaneal tibial nerve. The present application realizes the precise coverage and synergistic stimulation of the perineal area and the medial calcaneal tibial nerve, solves the problems of single-target point limitation, poor adhesion and inaccurate regulation and control of the traditional device, and significantly improves the effectiveness of fecal incontinence treatment and the patient's home use compliance.
