Spring controlled micropump for artificial anus sphincter

Abstract

The present invention relates to a spring-controlled miniature pump artificial anal sphincter, belonging to the field of medical equipment technology. It is characterized by that one end of first spring is fixed on a nut, its another end is fixed on first pressure plate, the first spring can be used for compressing the first pressure plate, so that said first pressure plate can be used for making fourth medical conduit branch tube and second medical conduit branch tube be compressed on the miniature motor end face so as to close the fourth medical conduit branch tube and second medical conduit branch tube; one end of second spring is fixed on the nut, its another end is fixed on the second pressure plate, the second spring can be used for compressing second pressure plate, said second pressure plate can be used for making first medical conduit branch tube and third medical conduit branch tube be compressed on the external shell so as to close the first medical conduit branch tube and third medical conduit branch tube. Said invention utilizes the control of translational direction of nut and utilizes the compression or tension of first spring and second spring to implement two-way excretion between first container and second container.

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 ...
