Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to drainage bags, in particular to an anti-backflow drainage bag. Background Art
[0002] The drainage bag is used to drain blood and fluid from inside the body or deep inside the surgical area after surgery. For some patients with excessive pleural effusion and ascites, they tend to ignore the amount of drainage after each drainage. Generally, a speed control alarm is set on the drainage bag, which will give a reminder when the set amount is reached. This can effectively prevent excessive drainage at a single time.
[0003] In the clinical nursing process, most of the drainage bags currently have only one flow channel when releasing the accumulated fluid and guiding it to the drainage bag. When encountering pleural effusion or ascites containing necrotic tissue or blood clots that are too large, blockage may occur, making it impossible to continue to release the accumulated fluid. Therefore, it is necessary to flush and dredge the pipeline. The commonly used method is to cut the drainage tube, insert the output end of the infusion pump into the drainage tube connected to the human body, and pressurize the saline bag at the input end to flush the drainage pipeline in the body, so as to achieve the purpose of unblocking. However, a new drainage bag needs to be replaced after flushing, which is a cumbersome process and causes waste. Utility Model Content
