Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multifunctional drainage bag. Background Art

[0002] Drainage bags are often used for bedside care of postoperative patients. The types of drainage tubes commonly used in hospitals vary, and the drainage tubes used in each department may be quite different, so each type of drainage tube requires an adapted drainage bag and drainage bag catheter connector. After different types of surgeries, it is very inconvenient for doctors in clinical departments to replace drainage bags for patients undergoing different surgeries.

[0003] At the same time, patients with abdominal drainage tubes or long-term indwelling urinary catheters need perfusion or flushing treatment in clinical practice. Conventional indwelling urinary catheters are double-lumen urinary catheters with only one outlet, and cannot be used for bladder flushing according to the principle of triple-lumen urinary catheters. Usually, the drainage tube interface is opened or a closed infusion set is used for puncture and flushing.

[0004] However, this method has high requirements for the puncture position of the scalp needle. There is a risk that the needle will pierce the end of the "Y"-shaped balloon, causing the catheter to accidentally slip off and easily lead to catheter infection. Each puncture and flushing will increase the risk of needlestick injuries. Repeated punctures can easily cause pipeline damage. At the same time, the drainage bag needs to be replaced each time the drainage bag interface is punctured, increasing medical expenses. Therefore, it is necessary to design a multifunctional drainage bag that improves universality and facilitates drug cleaning. Utility Model Content
