Medical manual vomica negative pressure suction drainage device

Abstract

The invention discloses a medical manual vomica negative pressure suction drainage device. The device comprises a negative pressure container and a drainage unit, the drainage unit comprises a drainage bag fixedly connected to the side wall of the negative pressure container, the drain outlet of the drainage bag is connected to a drainage pipe head with a drainage valve, the drainage bag is provided with a drainage pipe with a control valve and volume scale lines, and a digital display pressure sensor is arranged in the drainage bag; the drainage bag is provided with an air suction pipe head close to the drainage pipe, and the air suction pipe head is provided with a one-way membrane flap for preventing pus from flowing out; and the outer side wall of the hand-held end of the negative pressure container is provided with a groove, and the negative pressure container is provided with a negative pressure device for extracting air in the drainage bag. The drainage device is simple in structure and simple to operate, can accurately adjust the negative pressure of the drainage bag, can form stable and continuous negative pressure, enables pus to flow into the drainage bag at a uniform speed, completely avoids pus backflow caused by overlarge pressure and damage to tissues around a patient, is high in safety, and reduces the infection probability of the patient.

Description

technical field [0001] The invention relates to medical instruments, in particular to a medical manual abscess cavity negative pressure suction and drainage device. Background technique [0002] Clinically, for deep abscesses, a catheter is usually used to drain the pus in the patient's body. The traditional deep abscess catheterization is to place an ordinary surgical rubber drainage tube into the patient's body. This operation is difficult, traumatic, and the drainage tube has a large diameter, low comfort, inconvenient flushing, and poor drainage effect. At present, more and more clinicians recognize and accept the use of interventional radiology technology to place small-diameter drainage tubes for negative pressure drainage of deep abscesses. High, easy to carry and rinse, thorough drainage and other advantages. The existing negative pressure drainage device is composed of a negative pressure ball 1, a drainage tube 2 and a liquid discharge pipe 3, the liquid inlet ch...

AI Technical Summary

Problems solved by technology

When in use, the negative pressure ball 1 must be exhausted before it can be installed between the drainage tube and the discharge tube. Manually squeezing the negative pressure ball 1 cannot accurately control the negative pressure
