Abstract

The present invention relates to a roller type medical micro-pump to be used in artificial anal sphincter and pertains to the technical field of medical equipments, wherein: one end of a medical rubber tube is connected with a first container, the other end penetrates a hole which is arranged on an outer shell entering the internal surface of the outer shell, so as to wrap the internal surface of the outer shell of one circle, the medical rubber tube penetrates out of the internal surface of the outer shell through the other hole of the outer shell, the other end of the medical rubber tube is connected with a second container after penetrating out of the outer shell, a roller separates the medical rubber tube on the internal surface of the outer shell into sections which are not communicated with each other, the roller is connected with a rotary shaft, the rotary shaft drives the roller for synchronous rotation, at the same time, the roller can rotate around the shaft line of the roller thereof. The present invention can realize the two-way liquid drainage between the first container and the second container and can realize the function of pressure retaining at any position.

Description

technical field [0001] The invention relates to a pump in the technical field of medical devices, in particular to a roller-type medical micropump used for artificial anal sphincter. Background technique [0002] Fecal incontinence is a clinically common disease. 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%. underestimated. 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 many difficulties to nursing work. With the aging trend of the population With the development, fecal incontinence has become one of the clinical diseases that urgently need to be solved. [0003] Severe fecal incontinence is caused by the loss of function of the anal sphincter or the removal of the anal sphincter. The surgical treatment of this...
