Description

telescopic abdominal drainage tube

technical field

The utility model relates to the technical field of medical instruments, in particular to a telescopic abdominal drainage tube.

Background technique

The separation and incision of tissues during surgery may easily form tissue wounds, resulting in postoperative exudate and blood. Peritoneal washing is an important way to deal with infected wounds, but the washing fluid enters the interstitial space and is difficult to absorb during the operation. In order to prevent the incidence of complications such as peritoneal effusion, abdominal abscess and other complications caused by the accumulation of peritoneal washing fluid, exudate and oozing blood, and to observe whether there is active bleeding after surgery, it is often necessary after surgery with contaminated or large wounds. Indwelling abdominal drainage tube.

At present, the commonly used drainage tubes in clinical practice are single-tube multi-side hole tubes or anti-folding peritoneal drainage tubes with cross cores. These drainage tubes have side holes or slits on the wall at the head end to drain exudate or blood from deep wounds. Due to the gap between the parietal membrane and the greater omentum, that is, the exudate from the free surface of the abdominal cavity cannot be drawn out through the side hole of the drainage tube, so the exudate often overflows the body through the wall of the drainage tube. This phenomenon will not only cause panic in patients and their families, but also lead to abdominal retrograde infection after the gauze is infiltrated by the overflow fluid. In addition, changing the contaminated gauze will also increase the workload of clinical medical staff.
