背景技术 Background technique

[0002] 临床上应用的外科引流管种类很多，有的用于导尿，有的用于伤口，胸腔、脑腔、胃肠道、胆道等都有应用。外科引流为的是将人体组织间或体腔中积聚的脓、血、液体导引至体外，防止术后感染与影响伤口愈合。目前的引流管没有卡位结构，在***人体后，需要护理人员特别注意引流管的固定，患者稍微不注意容易造成引流管移位甚至脱出。引流管一旦移位或脱出，需要重新***病灶处，对患者造成身体上的再次痛苦。 [0002] There are many types of surgical drainage tubes applied clinically, some for catheterization, some for wounds, chest, brain cavity, gastrointestinal tract, biliary tract, etc. Surgical drainage is to guide the accumulation of pus, blood and liquid in the body tissue or body cavity to prevent postoperative infection and affect wound healing. At present, the drainage tube has no card structure. After being inserted into the human body, the caregiver is required to pay special attention to the fixation of the drainage tube, and the patient may not easily notice the displacement or even the escape of the drainage tube. Once the drainage tube is displaced or dislodged, it needs to be reinserted into the lesion, causing physical pain to the patient again.

[0003] 基于此，有必要设计一种具前端有卡位结构的引流管，防止引流管轻易从病灶处移位或脱出，避免患者受二次痛苦。 [0003] Based on this, it is necessary to design a drainage tube having a card structure at the front end to prevent the drainage tube from being easily displaced or dislodged from the lesion, thereby avoiding secondary pain to the patient.
