Micro-peristaltic pump for artificial anal sphincter system

Abstract

The invention relates to a micro-peristaltic pump for an artificial anal sphincter system in the technical filed of medical appliances, which comprises a first container, a connecting pipe, a rotating shaft, a motor, a speed reducer, rollers, a second container and a sleeve, wherein the first container is connected with the connecting pipe, and the connecting pipe is connected with the second container by penetrating through the sleeve; the two rollers are symmetrically arranged at the two sides of the motor, and divide the connecting pipe into two parts which are not communicated with each other, and the rollers are connected with the rotating shaft; and the rotating shaft is connected with the motor in a meshed way. The invention realizes the two-way drainage between a clamp sac and a liquid storage sac, and can realize the pressure holding function in any position.

Description

technical field [0001] The invention relates to a device in the technical field of medical instruments, in particular to a miniature peristaltic pump used in an artificial anal sphincter system. Background technique [0002] Anal incontinence seriously affects the normal life of modern people and has become a social problem. The incidence of this condition is often underestimated because patients are too shy to seek medical attention. Anal incontinence refers to the loss of the ability of the anal sphincter to control the excretion of feces and gas, which is a type of defecation disorder. Although anal incontinence is not fatal, it brings great physical and mental pain and inconvenience to patients, and even causes personality changes, which deserves the attention of clinicians. In addition, the treatment process also brings many difficulties to the nursing work. For example, the use of ostomy bags has brought great distress to patients and nursing. With the development o...

Problems solved by technology

Another disadvantage of this artificial anal sphincter is that the closing of the clamping capsule is achieved by the automatic return of the liquid inside the artificial anal sphincter system through the damping valve, and the patient cannot control the closing of the clamping capsule

Chinese invention patent biofeedback artificial anal sphincter system (public number: CN1718174) invented an artificial anal sphincter system, the structure includes artificial anal sphincter and artificial anal sphincter controller, wherein the main part of the artificial anal sphincter controller is a micro hydraulic pump , the micro hydraulic pump adopts the principle of a piston pump, and the stroke is long, resulting in a large structure of the micro hydraulic pump, which is difficult to implant into the human body

[0006] In summary, although the artificial anal sphincter system is an effective solution for the treatment of severe fecal incontinence, the function of the artificial anal sphincter system needs to be improved due to the shortcomings and deficiencies of the control pump.
