Drainage tube

Abstract

The invention relates to a drainage tube, comprising a drainage tube main body, wherein the back end of the drainage tube main body is a joint end, the front end of the drainage tube main body is a drainage head tube, three support strips extending along the length direction of the drainage head tube are arranged in the drainage head tube, the side edges of the three support strips are connected integrally in one length direction, the side edges of the three support strips in the other length direction are connected integrally with the inner wall of the drainage head tube, and a plurality of diversion holes are formed in both the pipe wall and the support strips of the drainage head tube. The drainage tube has the beneficial effects that the three support strips are arranged in the drainage head tube for supporting the drainage head tube, and the diversion holes are formed in the pipe wall and the support strips of the drainage head tube, so that purulence, blood and liquid can flow from a body into the drainage tube and can circulate in three cavities of the drainage tube; the whole drainage tube can be prevented from being blocked when the drainage tube is compressed in a human body or one cavity is blocked by blood clots and necrotic tissues; and the drainage tube is safe, reliable and simple in use.

Description

technical field [0001] The invention relates to a medical device, in particular to a drainage tube used for draining blood and secretions from an operation site after a surgical operation. Background technique [0002] The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body, and has the functions of preventing postoperative infection and promoting wound healing. There are many types of surgical drainage tubes used clinically, such as urinary catheters, pleural effusion drainage tubes, and peritoneal effusion drainage tubes. [0003] At present, hospitals at various levels in various places in my country generally adopt the following two measures for the drainage of blood and secretions at the surgical site: (1) directly insert a drainage strip at the surgical incision site, made of medical rubber, gauze, etc., and the drainage effect is poor. (2) Insert a medical rubber silicone tub...

Problems solved by technology

[0003] At present, hospitals at all levels in my country generally adopt the following two measures for the drainage of blood and secretions at the surgical site: (1) Insert a drainage strip directly at the surgical incision, made of medical rubber, gauze, etc., and the drainage effect is poor

(2) Insert a medical rubber silicone tube next to the suture opening. The head of the tube has several round or oval holes. There are no other devices on the tube. In order to prevent the drainage tube from slipping, a needle is sutured outside the skin to fix the drainage tube. Or fix it with a sticking device, the steps are cumbersome, and it cannot prevent the leakage of the drainage port, especially when the joint is flushed, it is easy to leak
