Biofeedback type artificial sphincter ani system

Abstract

A biologic feedback type artificial sphincter ani system is composed of an artificial sphincter ani consisting of silica gel pad, pressed bag, clamped bag, pressed catheter and clamped catheter, and an artificial sphincter ani controller consisting of pressure sensor and its regulator, miniature liquid pump and its driver, single-chip microprocessor, LCD, buzzer, push button, battery and PCB.

Description

technical field [0001] The invention relates to a system belonging to the technical field of medicine, in particular to a biofeedback artificial anal sphincter system. Background technique [0002] Defecation is mainly controlled by three factors, that is, the appropriate pressure of the anal sphincter: the anal sphincter maintains an appropriate pressure, which can prevent feces from flowing out of the rectum; the storage capacity of the rectum: the rectum has the function of expanding and storing feces. There is a sense of defecation; the rectum has a normal sensory function: it will convey the sense of defecation to the brain, and perform defecation behavior. Once there is a problem with any of the above three factors, it is easy to cause fecal incontinence. Anal incontinence refers to the obstacle of controlling defecation ability, which is one of the common diseases in anorectal surgery. Especially for some patients whose rectum and part of the colon have been resecte...

Problems solved by technology

The clinical application of muscle surgery is not ideal, and people began to turn their attention to artificial biomaterials to imitate the sphincter device from intestinal folding to various autologous muscle flap alternatives, all of which failed to obtain satisfactory results

In recent years, there have been reports in the world that the improved artificial bladder neck sphincter is applied to patients with loss of anal sphincter function, but it is limited to experimental and observational studies.

[0003] After searching the documents of the prior art, it is found that the Chinese Patent Publication No.: 2448319, the publication date is September 19, 2001, and the name of the utility model is: a biofeedback artificial pump type anal sphincter device, which includes: a switch, a fillable The in vivo device and the in vitro signal receiving and alarm device are composed of a cuff, a pump valve for controlling liquid filling, a liquid storage bag and a biofeedback signal transmitter. The device relies on a manually operated one-way valve to control the clamp pressure, so it cannot be controlled quantitatively. Clamp pressure, in addition, rely on permanent magnets and reed relays to measure pressure changes, pressure measurement is inaccurate, and it is impossible to quantitatively set the pressure threshold in the intestinal tract, and there is no data display function
