Abstract
The utility model discloses a medical negative-pressure anti-reflux drainage bag. A drainage catheter and a drain valve are arranged on a liquid storage bag body. A thin film bag is arranged in the liquid storage bag body. Two thin films which form the thin film bag are attached together. The thin film bag is provided with an outlet which is communicated with the inner chamber of the liquid storage bag body. An elastic air bag is arranged outside the liquid storage bag body and is connected with one end of an exhaust pipe. The exhaust pipe and the drainage catheter are respectively inserted into the thin film bag. Negative pressure can be continuously produced by squeezing the air bag, so that clinical drainage is enabled to be fuller, and the operation becomes simple and easy. Drained liquid or gas enters the liquid storage bag body. Since the two thin films of the thin film bag are closely attached together after the air bag is released, an anti-reflex effect is achieved, the phenomenon that the liquid or the gas flows reversely is avoided, and the probability that a patient is attacked by secondary infection is effectively reduced.
