Anti-blocking, anti-detachment and anti-seepage thoracic and abdominal effusion puncture drainage tube

Abstract

The invention relates to an anti-blocking, anti-detachment and anti-seepage thoracic and abdominal effusion puncture drainage tube, which comprises a drainage tube body, wherein the drainage tube bodycomprises a drainage section, a transition section and an outflow section arranged in sequence; a flusher, which is an elastic bladder structure arranged on the outside of the outflow section and iscommunicated with the drainage tube body; A sleeve sleeved and fixed to the outside of the transition section; a liner sleeved between the transition section and the sleeve to form a structure with aclosed cavity with the sleeve; a Heparin-gelatin sustained-release film layer is arranged on the inner side wall of the drainage section; a drainage bag interface is arranged at a free end portion ofthe outflow section; the invention reduces the operation flow during flushing and the risk of external infection, effectively reduces the occurrence of seepage and shedding phenomena of the anti-slipbag and the anti-shedding bag, reduces the occurrence of large particle condensate in the tube body by slowly releasing heparin, and effectively prevents the occurrence of pipe blockage.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a pleural and peritoneal effusion puncture drainage tube that prevents blocking, detachment and seepage. Background technique [0002] Puncture and drainage of pleural and peritoneal effusions are widely used in surgical treatment and tumor palliative treatment due to the advantages of small wound, less pain, and quick recovery. Usually, a method of using a puncture trocar and a drainage tube is used. Specifically, firstly, a puncture trocar is inserted into the thoracoperitoneal cavity to establish a channel, so that a drainage tube is implanted to drain the pleural and peritoneal effusion, and the extracted pleural and abdominal effusion is collected by the drainage bag. [0003] The current drainage tubes used in the puncture and drainage of pleural and peritoneal effusions mainly have the following problems: [0004] 1. It is easy to block; because the patient's ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is easy to block; because the patient's pleural effusion often contains red blood cells, serous cavity epithelial exfoliated cells, mucin and other components, it is easy to condense and block the drainage tube, making it difficult to discharge the pleural effusion. At this time, reverse flushing is required Drainage tubes increase the workload of medical staff;

[0005] 2. It is difficult to flush and easy to be infected; when the drainage tube is blocked, the drainage tube needs to be flushed in reverse, and the staff needs to open the injection end of the drainage tube to inject the flushing fluid. During this operation, external pathogenic bacteria and microorganisms may be brought into the chest and abdominal cavity , increase the risk of infection, and make the already weak patients worse;

[0006] 3. It is easy to loosen; the wall of the drainage tube is relatively smooth. If it is not fixed firmly after insertion, the drainage tube will slip off. At this time, it needs to be reinserted, causing unnecessary pain to the patient; Irritation in patients with sensitive skin, on the other hand, when the patient sweats, the adhesive force of the tape will decrease and fall off, causing the drainage tube to slip

[0007] 4. Exudation: At the initial stage of the drainage tube being inserted into the patient's chest and abdominal cavity, because the patient's muscle tissue, fat tissue and the drainage tube wall are closely attached, there will be no leakage of fluid in the chest and abdominal cavity along the outside of the drainage tube wall, and often After 24 hours, the adhesion force between the patient's muscle and fat tissue and the drainage tube wall decreased, and sometimes the fluid in the patient's thoracic and abdominal cavity leaked out along the outside of the drainage tube wall, causing discomfort and panic in the patient, and contaminating nearby devices, resulting in Decreased adhesion of the tape; in addition, when the muscle adipose tissue and the drainage tube wall are not tightly attached, skin colonization bacteria and in vitro pathogenic bacteria may reversely migrate into the thoracic and abdominal cavity and cause infection
