Description

Technical Field

[0001] The utility model relates to the technical field of drainage tubes, in particular to an anti-clogging drainage tube. Background Art

[0002] In surgical operations, drainage tubes used for drainage of fluid accumulation are a common device. They are mainly used to guide pus, blood, fluids, etc. accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. This type of drainage tube is widely used in clinical practice and is generally made of materials such as silicone rubber or polyurethane, with good biocompatibility and corrosion resistance. When in use, one end of the drainage tube is inserted into the drainage site in the body or on the wound surface, and the other end is connected to other external devices such as the drainage tube outside the body to drain to the outside of the body through the action of pressure such as internal pressure, gravity or negative pressure suction.

[0003] The working principle of medical effusion drainage tube is mainly to use the principle of siphon or negative pressure suction to guide the effusion, exudate or gas between human tissues or in the body cavity to the outside of the body, so as to prevent fluid accumulation from causing postoperative infection and promote wound healing and disease recovery.
