Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, and in particular to an ascites puncture and drainage device. Background Art

[0002] Abdominal effusion, also known as ascites, is a common clinical phenomenon. The occurrence of ascites may be related to a variety of diseases, including liver disease (such as cirrhosis), heart disease, renal insufficiency, cancer, infection, etc. Through abdominal puncture, a drainage tube is inserted from the anterior abdominal wall into the peritoneal cavity to drain the ascites to the outside of the body, which can eliminate symptoms such as dyspnea and abdominal pain caused by ascites. In the prior art, abdominal drainage has the following problems:

[0003] 1. In the prior art, adhesive tape is usually used to fix the abdominal drainage tube, but the fixing reliability of the adhesive tape is poor. After being fixed for a period of time, the drainage tube will become loose, and the drainage tube may slip outward, which will also affect the drainage of ascites.

[0004] 2. The contact part between the drainage tube and the wound is prone to ascites extravasation. Since the existing technology uses gauze to apply around the wound, the extravasated ascites will soak the gauze and irritate the skin around the drainage tube. The gauze covering makes it difficult to clean the ascites around the wound conveniently and timely. The ascites accumulated in the gauze in contact with the skin for a long time may cause skin dermatitis, eczema, ulceration and other problems.

[0005] Therefore, it is urgent to solve the problems existing in the above-mentioned ascites drainage. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a leakage-proof abdominal drainage device to help solve the common technical problems in the above-mentioned ascites drainage, such as the drainage tube is not firmly fixed, and the leaking ascites damages the skin around the wound.
