Description

Disposable multifunctional drainage tube accessory

Technical Field

The utility model relates to the field of drainage tubes, in particular to a disposable multifunctional drainage tube accessory.

Background

Some major operations are carried out, the operation wound surface is larger, exudation, blood seepage, necrosis and leakage accumulation can occur at the wound surface, for example, the bleeding and the necrosis are not cleared timely, the healing of the operation wound surface can be affected, even the operation wound surface is infected and anastomosed opening is caused seriously, serious abdominal cavity serious infection and great vessel hemorrhage can be caused by serious patients, and the death of patients is finally caused. The current clinical common solution is to drain the blood and the necrotic tissue out of the patient by using a negative pressure drainage technology, namely, a negative pressure drainage tube is arranged at the wound surface position, and effusion is drained by using negative pressure. Under the general condition, the negative pressure drainage tube is easily sealed by necrotic tissues in the suction process, so that the negative pressure suction tube cannot work normally, and postoperative recovery is affected. Furthermore, when an anastomotic fistula occurs at the wound anastomotic stoma, the contents of the alimentary canal and digestive juice leak out to the periphery of the anastomotic stoma, if the leakage liquids cannot be timely led out, the risk of infection and hemorrhage can be increased rapidly, and exogenous sterile physiological saline is needed to wash the local part, dilute the leakage liquids and drain the leakage liquids.

In the prior art, as shown in fig. 1, a flushing pipe 2 is manually reserved in a catheter 1, so that the drainage and flushing functions can be basically realized, but the following problems exist in doing so: without special reservation of the irrigation tube channel, manual retention can lead to breakage of the catheter 1, resulting in incomplete aseptic disposal, and thus poor sterile environment for culture. The irrigation tube 2 is placed in the catheter 1 body, and needs to be opened on the catheter 1, so that operation burden is increased in the operation of indwelling, and additional consumable materials are needed. Thus, there is a need for a drain tube connection that is sterile, environmentally friendly, and convenient for flushing operations.
