Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an abdominal drainage and irrigation tube. Background Technique

[0002] At present, before the end of general abdominal surgery, an abdominal drainage tube is generally placed at the potentially infected position for postoperative drainage and close observation. In most cases, the conventional drainage tube placement meets the drainage requirements, but in type II surgeries, gastrointestinal fistulas occasionally occur, causing intra-abdominal infections and resulting in unsmooth drainage and blocked tubes. For such surgeries that may be infected, some clinics may choose to use the Li's drainage tube, which is usually a double-tube structure. Among them, one end of the outer tube is sealed, and a plurality of through holes are evenly distributed on the tube wall near the sealed end of the outer tube. When in use, the sealed end of the outer tube is inserted into parts such as the abdominal cavity and intestine with effusion, and then the suction tube is inserted into the outer tube for suction.

[0003] However, when the above-mentioned drainage tube sucks the liquid around the affected tissue, it is easy to adhere to the tissue, and may also cause damage to the tissue due to the suction force, resulting in poor surgical effects; therefore, it is necessary to improve the current abdominal drainage and irrigation tube to meet the usage requirements.

The size of the gap can be customized according to the usage requirements. One end of the movable inner tube 12 is connected to the flushing inner cavity of the extension section 2, and the other end extends out of the outer sleeve 11. In order to prevent liquid leakage at the connection between the two, the connection part needs to be sealed.
