Medical minitype pump used for artificial anus sphincter

Abstract

The present invention relates to the technological field for medical instrument, which comprises a medical micro pump used in artificial anus sphincter. Among the present invention, one end of the output shaft of the motor is directly connected with the screw rod. The screw rod is connected with a nut plate, which is close to a piston cavity. The other end of the motor is directly connected with a reducer. The output shaft of the reducer is directly connected with a cam wheel device. The first medical catheter is connected with a piston cavity through a first one-way valve. The first medical catheter is divided into two paths, which is connected with a second switch and a third switch, respectively. The second switch and the third switch are connected with a first vessel and a second vessel through the cam wheel. The second medical catheter is connected with a piston cavity through a second one-way valve. The second medical catheter is divided into two paths, which is connected with a first switch and a fourth switch, respectively. The first switch and the fourth switch are connected with a first vessel and a second vessel through the cam wheel. The present invention is capable of realizing bidirectional fluid discharging between a Schnabel bag and a liquid storage bag. The present invention is also capable of realizing pressure-keeping function in any position.

Description

technical field [0001] The invention relates to a micropump in the technical field of medical instruments, in particular to a 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 fe...

Problems solved by technology

[0006] Aiming at the defects of the existing artificial anal sphincter control pump, the present invention provides a medical micropump for the artificial anal sphincter, which is installed between the clamp bag and the liquid storage bag of the artificial anal sphincter, and realizes the pump in the clamp bag. Two-way liquid drainage between the reservoir bag and the pressure holding function can be realized at any position
