Problems solved by technology

[0002] At present, most of the abdominal drainage tubes used clinically are single-channel tubes made of latex or silicone rubber with a side hole at one end. This kind of drainage tube is mainly used for short-term indwelling in the abdominal cavity after abdominal surgery to drain the abdominal cavity. The purpose of effusion or blood accumulation, but the biggest disadvantage of this kind of tube is that it cannot perform peritoneal washing, especially for patients with bile leakage and pancreatic leakage after upper abdominal surgery, it is often necessary to re-place the tube in the peritoneal drainage tube to perform peritoneal washing , this is not only cumbersome to operate but also increases the chance of infection for the patient. In addition, the effective lumen of the drainage tube is reduced due to the re-insertion of the tube in the original drainage tube, which is not conducive to drainage.
At present, there are also double cannula for peritoneal irrigation and drainage, but this kind of double cannula for peritoneal irrigation and drainage also has its structural disadvantages, mainly because the irrigation tube is located in the drainage tube and occupies the lumen of the drainage tube, which will affect the drainage effect

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] refer to figure 1 with figure 2 , a peritoneal drainage tube with flushing function, comprising a drainage tube 1, a flushing tube 2 and a flushing tube connector 3, the flushing tube 2 is located on the side wall of the drainage tube 1, the end of the flushing tube 2 is separated from the drainage tube 1, and the flushing tube The joint 3 is connected to the end of the flushing pipe 2.

[0012] The drainage tube 1 is made of latex or silicone rubber.

[0013] The working principle of the present invention is: the head end of the drainage tube 1 can be trimmed to have a plurality of side holes according to needs, and then placed in the patient's abdominal cavity during the operation, the end of the drainage tube 1 and the flushing tube joint 3 are located outside the patient's abdominal wall, and the flushing is performed during flushing. The flushing flui...

Abstract

An abdominal cavity drainage tube with a washing function comprises a drainage tube, wherein a washing tube is arranged on the side wall of the drainage tube, the tail end of the washing tube is separated from the drainage tube, and a connector of the washing tube is connected with the tail end of the washing tube. The head end of the drainage tube after being cut into a head end with a plurality of side holes can be placed in an abdominal cavity of a patient in operation. The tail end of the drainage tube and the connector of the washing tube are placed outside the abdominal cavity of the patient. During washing, washing liquid enters the washing tube through the connector of the washing tube, then enters the abdominal cavity, and flows out from the drainage tube. The abdominal cavity drainage tube has washing and drainage functions, avoids replacement of a tube when a single-channel abdominal cavity drainage tube is used in clinic, reduces opportunities of clinic operations and patient infection, and overcomes the structural defect of abdominal cavity washing and drainage double-tube.

Description

technical field [0001] The invention relates to a medical abdominal drainage tube, in particular to a abdominal drainage tube with flushing function. Background technique [0002] At present, most of the abdominal drainage tubes used clinically are single-channel tubes made of latex or silicone rubber with a side hole at one end. This kind of drainage tube is mainly used for short-term indwelling in the abdominal cavity after abdominal surgery to drain the abdominal cavity. The purpose of effusion or blood accumulation, but the biggest disadvantage of this kind of tube is that it cannot perform peritoneal washing, especially for patients with bile leakage and pancreatic leakage after upper abdominal surgery, it is often necessary to re-place the tube in the peritoneal drainage tube to perform peritoneal washing In this way, not only the operation is cumbersome, but also the chance of infection will be increased by re-inserting the tube. In addition, because the tube is re-pl...
