Spring controlled micropump for artificial anus sphincter

Abstract

The invention relates to a spring-controlled micropump for artificial anal sphincter in the technical field of medical devices, wherein: one end of a first spring is fixed on a nut, and the other end is fixed on a first pressing plate, and the first spring compresses the first pressing plate so that The first pressing plate compresses the fourth medical catheter branch pipe and the second medical catheter branch pipe on the end face of the micro-motor, and separates the fourth medical catheter branch pipe and the second medical catheter branch pipe. One end of the second spring is fixed on the nut, and the other end is fixed on the second pressure plate. The second spring compresses the second pressure plate, so that the second pressure plate compresses the first medical catheter branch pipe and the third medical catheter branch pipe in the outer shell, and the first medical catheter branch pipe is cut off. Catheter branch and third medical catheter branch. Control the translational direction of the nut, compress or stretch the first spring and the second spring, realize bidirectional liquid discharge between the first container and the second container, and realize the function of maintaining pressure at any position.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, which is a spring-controlled micro-pump used for artificial anal sphincter. Background technique [0002] Fecal incontinence is a clinically common disease. There are many reasons for fecal incontinence, such as incontinence caused by nervous system, perineal trauma, anorectal disease, congenital anorectal malformation, obstetrics and gynecology, and anorectal surgery. disease and many other reasons. According to statistics, the incidence rate of adults is as high as 2%, and the incidence rate of people over 65 years old can reach 7%. In fact, the incidence rate of this disease is often underestimated because patients are ashamed to seek medical treatment. Fecal incontinence refers to the loss of the anal sphincter's ability to control the excretion of feces and gas. It is easy to cause a variety of complications, which not only brings great pain to patients, but also brings ...

Problems solved by technology

[0005] Aiming at the defects of the existing artificial anal sphincter control pump, the present invention provides a spring-controlled micro-pump for the artificial anal sphincter, which is installed between the clamp bag and the liquid storage bag of the artificial anal sphincter, and is realized in the clamp bag. Two-way liquid drainage between the pouch bag and the liquid storage pouch bag, and the pressure maintaining function can be realized at any position, improving the function and performance of the existing artificial anal sphincter system control
