Description

Disposable drainage bag with one-way exhaust and backflow prevention functions

Technical Field

The utility model relates to a disposable medical drainage bag capable of performing one-way exhaust and preventing countercurrent, belonging to the technical field of medical instruments.

Background

Drainage is a common means in medical treatment, and aims to discharge exuded liquid at a wound or to urinate and store urine for a patient with difficulty in urination. At present, drainage is carried out by adopting a drainage bag, and the universal disposable drainage bag consists of an adaptive joint, a drainage catheter, a film bag body, a flow stopping clamp, a drainage switch and a fixing part. The fixing part is divided into a button, a bandage and a sling according to the using mode of a patient, the button is suitable for leg-hung and waist-hung drainage bags, the bandage is suitable for the leg-hung drainage bag, and the sling is suitable for the waist-hung drainage bag. When the drainage bag is used, the adaptive joint is connected with the external joint of the drainage catheter, the button, the hanging strip or the bandage at the upper end of the drainage bag is fixed, and then the flow stopping clamp is adjusted to enable liquid to enter the drainage bag through the drainage catheter.

In use, the current disposable drainage bag has some defects. At first, current drainage bag against current that prevents is totally enclosed structure, and after gastrointestinal tract operation, often can have gas to follow liquid entering drainage bag in the gastrointestinal decompression drainage, gas is the accumulation in the drainage bag, make the atmospheric pressure in the drainage bag increase, there is very big influence to liquid entering drainage bag, lead to the drainage to go on smoothly even, consequently medical staff must often observe the drainage bag and whether have gas, and need in time discharge, prevent to influence the drainage, and the work load has been increased, the going on smoothly of drainage has been influenced. Secondly, the anti-reflux device of current disposable drainage bag is two films, and two films overlap the feed liquor end of connecting in the drainage bag, and the feed liquor pipe passes in the drainage bag behind the drainage bag, and the feed liquor pipe is located between two films. When the drainage bag is used, liquid flows out of the liquid outlet of the liquid inlet pipe and flows into the drainage bag from between the two films; when no liquid flows out from the liquid outlet of the liquid inlet pipe, the two films are tightly attached, and the liquid in the drainage bag can not reversely enter the liquid inlet pipe, so that the purpose of preventing countercurrent is achieved. Because the two films are longer, the situation that parts of the two films are not tightly attached sometimes occurs, and liquid can permeate into the space between the two films, so that the effect of preventing the backflow is influenced.

In view of the above disadvantages of the existing disposable anti-reflux drainage bag, it is necessary to improve the drainage bag.

SUMMERY OF THE UTILITY MODEL
