Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a drainage device and method for postoperative nursing of medical surgery. Background Art

[0002] In clinical work, for most surgical patients, in order to discharge the exudate and blood in the body in time and prevent complications such as postoperative infection and delayed wound healing, it is often necessary to drain the accumulated fluid and blood in the wound through a drainage device after surgery. Among the existing drainage devices, most of them are negative pressure bag structures. By pressing the bag to discharge the air inside, negative pressure can be formed, so that the drainage tube or blood and other liquids in the patient's wound are drained into the bag.

[0003] The liquid outlet end of the existing drainage tube is connected to the liquid inlet end of the liquid storage tank by plugging. Since there is no better way to fix them, when the patient moves and turns over, the drainage tube is easy to fall off from the liquid storage tank, affecting the subsequent use of the device and causing great safety hazards.
