Description

A multifunctional drainage tube and method of using the same

Technical field:

The invention relates to the technical field of medical devices, in particular to a multifunctional drainage tube and a method for using the same.

Background technique:

Drainage tube is a medical device commonly used after surgery to drain blood, exudate or purulent secretions accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. For example, the patent No. ZL201821128307.X provides a joint cavity irrigation and drainage tube, including the irrigation tube and the drainage tube that are parallel and directly connected to the side. When in use, only one opening can be opened at the joint skin of the patient, that is The irrigation and drainage tube can be inserted into the joint cavity. At the same time, the irrigation and drainage tube is directly connected by the side of the irrigation tube and the drainage tube. There is no excess distance between the two, and the opening is not too large. Therefore, the joint cavity lavage drainage tube can effectively reduce the number of wounds and the pain of the patient during activities, and at the same time, it is convenient to deal with the blockage of the pipeline, add liquid, reduce the operation pollution of drainage sampling, and improve the accuracy of the examination. However, because the surgical drainage tubes used clinically are mostly soft silicone tubes, medical staff often use vascular forceps to implant the drainage tube between body tissues or body cavities, and then remove the vascular forceps, leaving one end of the drainage tube indwelling. In the body tissue or body cavity, the vascular clamp is easy to contact with the drainage tube during the process of taking it out from the body tissue or body cavity, so as to bring out the drainage tube or loosen the other drainage tube, resulting in the placement of the drainage tube. It is time-consuming and laborious to take out the drainage tube during the removal of the forceps.
