Abstract

The invention discloses a drainage catheter which comprises a catheter body which is provided with a drainage cavity channel and a particle cavity channel. An elastic film is disposed in a catheter cavity of the catheter body, can be pressed to deform and is used for dividing the catheter cavity into the drainage cavity channel and the particle cavity channel. When the drainage catheter is applied, since the elastic film is disposed in the catheter body of the drainage catheter, when drainage is performed, pressures on the two sides of the elastic film are different, so that the elastic film is protruded towards the side of the particle cavity channel, and the drainage cavity channel can be obviously enlarged to facilitate drainage; when particle leading in is performed, the elastic film contacting with radioactive particles is protruded towards the side of the drainage cavity channel to facilitate the particle leading in. In conclusion, by application of the drainage catheter, the problem of poor circulation of the cavity channels in the double-acting drainage catheter can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a drainage catheter. Background technique [0002] Drainage catheter is a medical device widely used in clinical surgery. It is used to remove irritating substances such as effusion, blood accumulation, and empyema, reduce exudate retention, and promote inflammation to subside, thereby facilitating wound healing and preventing new infections. and diffusion, while local pathological changes can be observed. At present, there are many types of drainage tubes used clinically, including drainage tubes for the urethra, brain cavity, chest cavity, and gastrointestinal tract. Although the materials and structures are slightly different, they are generally single-lumen tubes with a single purpose. [0003] It is clinically found that the treatment site of the drainage tube is often accompanied by cancerous tissue, such as malignant obstructive jaundice, malignant biliar...
