Description

Technical Field

[0001] The utility model relates to the technical field of drainage tubes, in particular to a circulation punching drainage tube. Background Art

[0002] There is no consensus on the method of abdominal drainage in case of pancreatic fistula after pancreaticoduodenectomy. The drainage effect of pancreatic fistula is poor, which can easily cause adverse consequences such as abdominal infection, bleeding, and even death of the patient. The problem of how to perform unobstructed abdominal drainage for pancreatic fistula still troubles surgeons. At present, the main method of placing abdominal drainage tubes for pancreatic fistula is proposed by some scholars to rely solely on double-cannula flushing and negative pressure drainage. This drainage method is also a circulating drainage. Specifically, a thinner inner tube is inserted through the opening of the outer cannula, and the flushing fluid is flushed through the outer tube, and then the liquid is drained by suction through the inner tube; vice versa, that is, the flushing fluid is flushed through the inner tube, and the liquid is drained by suction through the outer tube.

[0003] When implementing this technical solution, there are at least the following defects: Although the existing abdominal drainage tube can drain the patient's pancreatic fistula, the effect is not particularly ideal, and there are the following defects: 1. Double-tube flushing negative pressure drainage, although it is also a circulation drainage, but due to the open structure, the outside world is connected to the abdominal cavity, which is easy to cause abdominal infection, and the double-tube drainage is actually farther away from the pancreaticojejunostomy than the two negative pressure ball drainage tubes on the left side of this study, and serious complications still occur. 2. Drainage by negative pressure suction can only be done by suction, but once the drainage tube is blocked by necrotic floccules, it is often impossible to completely clear the drainage tube by suction. Therefore, we propose a circulating flushing drainage tube. Utility Model Content

[0004] The utility model aims to provide a circulating punching drainage tube, which solves the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a cyclic punching drainage tube, comprising a first drainage tube, a second drainage tube is arranged on one side of the first drainage tube, one end of the first drainage tube is connected with one end of the second drainage tube through a connecting line, and a first sealing member and a second sealing member are arranged in an inner cavity of one end of the first drainage tube;

[0006] The first seal and the second seal are both arranged in an annular shape, and are fixedly bonded to the inner cavity of the first drainage tube. A gasket is bonded to the inner side of the first seal, and a rubber ring is bonded to the inner side of the second seal, and the inner diameter of the rubber ring is smaller than the inner diameter of the gasket.

[0007] By adopting the above technical scheme, the first drainage tube can be placed in front of the pancreaticojejunostomy and the second drainage tube can be placed in the back, and both drainage tubes can be led out of the body through the left upper abdomen, which solves the problem that the open structure allows the outside world to communicate with the abdominal cavity, which is easy to cause abdominal cavity infection. In addition, the double-tube drainage is actually farther away from the pancreaticojejunostomy than the two negative pressure ball drainage tubes on the left side of the present study, which is very likely to cause complications. When blockage occurs during the drainage process, the sealing of the syringe can be guaranteed, which further facilitates the syringe to completely push the air pressure or water pressure into the first drainage tube, thereby discharging the pus or necrotic flocs in the drainage tube through the connecting line into the second drainage tube and being pushed out by the air or water pressure, thereby fully circulating and draining the pancreatic fistula exudate around the pancreaticojejunostomy, further ensuring the working effect of the drainage tube.

[0008] Optionally, a plurality of rubber protrusions are bonded to the inner side of the gasket, and the rubber protrusions are distributed in a ring shape.

[0009] By adopting the above technical solution, the insertion end of the syringe can be positioned by cooperating with a plurality of annularly arranged rubber protrusions.

[0010] Optionally, side holes are provided on both the front and rear sides of the first drainage tube and the second drainage tube, and the plurality of side holes are equidistantly distributed.

[0011] By adopting the above technical solution, it is easy to cooperate with the side hole, thereby ensuring smooth drainage and ensuring that the drainage tube can drain effectively.

[0012] Optionally, the outer diameter of the first drainage tube is greater than the outer diameter of the second drainage tube, and the length of the first drainage tube is greater than the length of the second drainage tube.

[0013] By adopting the above technical solution, the length of the pipeline remaining outside the body is ensured to be consistent.

[0014] Optionally, the connecting line is arranged at the ends of the first drainage tube and the second drainage tube, and the connecting line is made of absorbable material.

[0015] By adopting the above technical solution and setting the connecting line, the first drainage tube and the second drainage tube form a circulation passage.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] The technical solution of the present application, through the provision of a first drainage tube, a second drainage tube, a connecting line, a first sealing member, a rubber bump and a rubber ring, can be placed in front of the pancreatico-enteric anastomosis through the first drainage tube, and the second drainage tube is placed at the rear, and both drainage tubes are led out of the body through the left upper abdomen, thereby solving the problem that the open structure allows the outside world to communicate with the abdominal cavity, which is easy to cause abdominal cavity infection, and the double-tube drainage is actually farther away from the pancreatico-enteric anastomosis than the two negative pressure ball drainage tubes on the left side of the present study, which is very likely to cause complications. When blockage occurs during the drainage process, the sealing of the syringe can also be guaranteed, and it is further convenient for the syringe to completely push the air pressure or water pressure into the first drainage tube, so that the pus or necrotic flocs blocking the first drainage tube are discharged into the second drainage tube through the connecting line and pushed out by the air or water pressure, thereby fully circulating and draining the pancreatic fistula exudate around the pancreatico-enteric anastomosis, further ensuring the working effect of the drainage tube.
