Abdominal drainage tube

Abstract

The invention discloses an abdominal drainage tube, comprising an outer drainage tube and an inner irrigating tube; one end of the inner irrigating tube is provided with an inflating balloon and is inserted into the outer drainage tube, the other end of the inner irrigating tube is provided with an irrigating tube, a vent tube and an air access tube communicated with the inflating balloon, a drainage passage is formed between the inner wall of the outer drainage tube and the outer wall of the inner irrigating tube, and the sidewall of the outer drainage tube is provided with a plurality of side drainage holes. Protections such as the inner irrigating tube and the inflating balloon are arranged in the outer drainage tube, good anti-blocking effect can be achieved, effective continuous irrigation and drainage are achieved, problems due to the drainage tube being placed not in position due to tube change for blocking problem are avoided, frequently adjusting the position and direction of the drainage tube is not required, and both patients' pain and workload of medical staff are relieved.

Description

technical field [0001] The invention relates to a device in the field of medical device research, which is used to guide liquids such as blood seepage, empyema and empyema accumulated between human tissues or body cavities to the outside of the body, especially a device for continuous flushing, drainage and anti-clogging. Abdominal drainage tube. Background technique [0002] After abdominal surgery, peritoneal bleeding, exudate, empyema and infection are very common, often accumulate in the abdominal cavity or in the surgical field, damage tissue, secondary infection or aggravate infection, so it is necessary to place a drainage in the abdominal cavity to drain the abdominal pus Drain the abdominal cavity and necrotic tissue from the abdominal cavity to the outside, prevent the spread of infection, promote the reduction or closure of the surgical field dead space, and promote the healing of the anastomotic stoma and incision in the abdominal cavity. For example, in the cas...

Problems solved by technology

The simple use of antibiotics cannot improve the control rate of abdominal infection, and the effect must be achieved on the basis of adequate drainage

However, in patients with gastrointestinal fistula or abdominal infection, the peritoneal drainage fluid is often very viscous, and it is difficult for the necrotic substances in the abdominal cavity to be discharged through the ordinary drainage tube.

Clinically, the existing drainage tubes are continuously dripping and diluting and flushing the infection focus while actively attracting them, but there are two major problems: 1. Poor patency: the position, number and size of the side holes in the intraperitoneal tube wall are unreasonably designed, resulting in flushing The scope of the drainage tube is too small, the flushing flow rate and speed are too low, and the impact force on the thick blockage is insufficient. When the blockage condenses to a certain extent, the negative pressure suction effect of the drainage tube is greatly weakened; 2. Residual fluid is easy to remain during extubation: The design of the number and size of side holes in the tube wall is not enough to adequately drain the accumulated fluid in the abdominal cavity
