Description

Technical Field

[0001] The utility model relates to the technical field of suction devices for abdominal surgery, in particular to an abdominal suction tube. Background Art

[0002] Abdominal suction tubes are devices used to draw fluid from the human abdominal cavity to the outside of the body during surgery, to prevent postoperative bleeding, exudation, pus infection, etc., and to promote wound healing. The basic structure of existing abdominal suction tubes includes an inner tube and an outer tube. The outer tube is provided with multiple suction holes at the distal end, but has no holes at the proximal end. The outer tube and the inner tube are connected together. When a traditional abdominal suction tube is in use, under the action of negative pressure, the holes distributed on the outer tube will not only allow the fluid in the abdominal cavity to flow in, but will also attract the omentum, internal organs and other tissues near the holes. The omentum, internal organs and other tissues can easily block the holes, resulting in a blocked process of drawing the fluid and poor drainage effect. Moreover, once the omentum, internal organs and other tissues are sucked into the holes, they will be damaged, and in severe cases, the inflamed area will bleed again, increasing the patient's pain and reducing the effectiveness of surgical treatment.

[0003] Chinese patent CN204502055U discloses a peritoneal suction cannula that is less likely to damage the greater omentum. The cannula has holes distributed throughout its outer wall. When the outer tube is partially immersed in the peritoneal fluid, the holes remain above the liquid level, reducing the negative pressure attraction of the holes and minimizing damage to the greater omentum that is drawn into the cannula. However, this still fails to address the problem of tissues such as the omentum coming into close proximity and blocking the holes in the outer tube. Furthermore, any damage to the omentum and other tissues increases the patient's pain and reduces the overall effectiveness of the surgical treatment. Utility Model Content

[0004] The purpose of the utility model is to provide an abdominal suction tube to solve the problems existing in the above-mentioned prior art. It can prevent the omentum, viscera and other tissues from blocking the suction tube during surgery, reduce damage to the omentum tissue, ensure a smooth drainage process, alleviate the patient's pain, and improve the overall effect of surgical treatment.

[0005] To achieve the above purpose, the present invention provides the following solutions:

[0006] The utility model provides an abdominal suction tube, comprising a suction tube and an exhaust tube, wherein the exhaust tube is sleeved outside the suction tube and an air intake channel is formed between the exhaust tube and the suction tube, and both ends of the exhaust tube are sealed and fixedly connected to the outer wall of the suction tube, the suction tube has an inlet and an outlet, the inlet is communicated with the outside and is used to extend into the abdominal cavity and suck the accumulated fluid in the abdominal cavity, the outlet is used to be sealed and connected to the suction tube, the exhaust tube is sealed and fixedly connected on the side wall near the outlet and is communicated with the air intake tube, the air intake tube can provide gas to the exhaust tube, and a plurality of exhaust holes are provided on the side wall of the exhaust tube near the inlet, and the exhaust holes can discharge the gas in the exhaust tube.

[0007] Preferably, it further comprises a rubber cover, which is tightly fitted on the outer wall of the exhaust pipe.

[0008] Preferably, the rubber sleeve can slide on the outer wall of the exhaust pipe along the axis of the exhaust pipe, thereby closing at least a portion of the exhaust hole.

[0009] Preferably, the axis of the suction pipe coincides with the axis of the exhaust pipe.

[0010] Preferably, a valve is provided on the air inlet pipe.

[0011] Preferably, the suction pipe and the exhaust pipe are integrally formed during manufacture.

[0012] Preferably, the exhaust holes are evenly distributed on the side wall of the exhaust pipe.

[0013] Compared with the prior art, the utility model has achieved the following technical effects:

[0014] The utility model provides an abdominal suction tube, wherein the exhaust tube is fixedly sleeved on the outer wall of the suction tube, and the two end faces of the exhaust tube are sealedly connected to the outer wall of the suction tube. When the abdominal suction tube is used to attract the accumulated fluid in the abdominal cavity, the inlet of the suction tube extends into the abdominal cavity and absorbs the accumulated fluid in the abdominal cavity. At the same time, the gas discharged from the exhaust hole of the exhaust tube can blow open the omentum, viscera and other tissues around the inlet of the suction tube, ensuring that there is no adhesion of the omentum, viscera and other tissues at the inlet of the suction tube, making the drainage process smoother; and the omentum, viscera and other tissues will not be sucked into the inlet of the suction tube, thereby reducing the damage of the omentum, viscera and other tissues, alleviating the patient's pain, and improving the surgical treatment effect.

The inlet 9 of tube 1 is close to the effusion in the abdominal cavity, and then the inflation device connected to the trachea 5 is opened, and the trachea 5 is sealed and connected to the air inlet pipe 4, so that the gas passes through the trachea 5, the air inlet pipe 4 and the exhaust pipe 2 in turn and is discharged from the exhaust hole 7. The gas discharged from the exhaust hole 7 can blow open the omentum, viscera and other tissues around the abdominal suction tube, avoiding the omentum, viscera and other tissues from being sucked into the inlet 9 of the suction tube 1, causing blockage of the inlet 9 of the suction tube 1, and can also reduce damage to the omentum, viscera and other tissues. Then open the suction device and absorb the effusion in the abdominal cavity from the inlet 9 of the suction tube 1. At this time, there is no omentum, viscera and other tissues attached to the inlet 9 of the suction tube 1, which can make the drainage process smoother, reduce the patient's pain, and improve the surgical treatment effect.
