Thoraco-abdominal cavity drainage tube

Abstract

The invention discloses a thoraco-abdominal cavity drainage tube which comprises a guide tube. Two ends of the guide tube are a drainage input end and a drainage output end, wherein the drainage inputend is inserted into a thoraco-abdominal cavity, and the drainage output end remains outside the thoraco-abdominal cavity. The drainage input end is provided with a plurality of drainage holes, a floodable flexible water bag sleeve externally sleeves the drainage tube and is connected with a water injection component and provided with a wrapping portion, the wrapping portion tightly wraps the guide tube when water is not injected into the flexible water bag sleeve, the wrapping portion is expanded to form an expanding inner cavity after water is injected into the flexible water bag sleeve, the drainage input end and all the drainage holes are positioned in the expanding inner cavity, and the wrapping portion is provided with a plurality of filter holes communicated with the expanding inner cavity and an external environment. The thoraco-abdominal cavity drainage tube has the advantages of simple structure, low cost, convenience in use and operation, capability of realizing thorough drainage without adjustment and the like.

Description

Technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a thoracic and abdominal cavity drainage tube for drainage of pleural and abdominal effusions. Background technique [0002] The purpose of drainage of thoracic and abdominal cavity is to guide the pus, blood, exudate and other fluid accumulated in the pleural cavity and peritoneal cavity to the body to treat or prevent further deterioration of the disease. The current drainage tube is mostly a single hollow tube, its nozzle and side hole are small, it is easy to be blocked by blood clots, fibrous tissue or necrotic tissue, resulting in the need for re-intubation, and re-intubation will increase the risk of infection, The patient’s pain and economic burden have also brought inconvenience to the work of medical staff. In addition, the current drainage tube is designed with a sharp tip for the convenience of intubation. After the pleural effusion is reduced, the lungs will exp...

AI Technical Summary

Problems solved by technology

Most of the current drainage tubes are single hollow tubes with small nozzles and side holes, which are easily blocked by blood clots, fibrous tissue or necrotic tissue, resulting in the need for re-intubation, which will increase the risk of infection. The pain and financial burden of patients also brings inconvenience to the work of medical staff; moreover, for the convenience of intubation, the current drainage tube has a sharper tip design, and after the pleural and peritoneal effusion is reduced, it will directly expand with the expansion of both lungs. Stimulate the lungs and other internal organs, causing pain and discomfort in patients

More importantly, the existing drainage tube cannot sink with the reduction of effusion, resulting in incomplete drainage
