[0002] Peritoneal and pleural effusion drainage is a common treatment method in tumor surgery, which is used to relieve the pressure of peritoneal effusion caused by various reasons during tumor surgery and improve the symptoms of patients. In this process, it is crucial to ensure that the drainage position of the drainage tube is correct. However, the conventional drainage tube has the problems that the drainage position of the head end of the drainage tube cannot be accurately placed and adjusted, and improper drainage position may lead to poor drainage and affect the treatment effect.

[0003] The existing patent document with the publication number CN118873819A discloses a peritoneal drainage tube device, which is provided with an adjusting hose inside the drainage tube.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] By designing a rigid adjustment branch tube below the main abdominal drainage tube, along with an adjustment and fixing ring and assembly, a movable pushing shim rotates the entire adjustment tube. Pressing the pushing shim pulls the tension line, causing the gate to squeeze the adjustment protrusion. This causes the upper hollow tube of the rigid adjustment branch tube to shift and the lower hollow tube to deflect. The downward deflection of the rigid adjustment branch tube adjusts the position of the rigid connecting branch tube and the abdominal drainage branch tube, making the drainage position easy to adjust. The operation is simple, and the adjustment of the drainage position is easy to control. Furthermore, a ring-shaped airbag mounting bracket and a hemispherical airbag mounting bracket are designed. The frame ensures that each squeeze of the gate and adjusting protrusion creates a coordinated effect that squeezes the outer and inner air bladders. After the outer and inner air bladders are squeezed, the internal gas is discharged through the air duct into the annular air bladder, causing it to expand and squeeze the connecting tube. This causes the connecting tube to contract to a certain extent, indirectly releasing the pressure at the drainage site and reducing the risk of mucosal damage or bleeding. The contraction and pressure release of the connecting tube can also break down or loosen the thick secretions or tissue fluid inside the abdominal drainage branch, preventing blockage of the drainage hole of the abdominal drainage branch. It is especially suitable for scenarios such as abdominal surgery drainage in oncology surgery. Attached Figure Description

Embodiment three

[0038] Please refer to Figure 1 to Figure 15, on the basis of embodiment two, in order to limit the hard adjustment branch pipe 231, the embodiment also proposes that the lower inner surface of the fixed pipe 21 is fixedly installed with a hemispherical air bag mounting frame 26, the inner surface of the hemispherical air bag mounting frame 26 is fixedly installed with a limiting sleeve matched with the lower hollow ball pipe of the hard adjustment branch pipe 231, the outer surface of the hemispherical air bag mounting frame 26 is fixedly installed with an outer air bag 261, the inner surface of the hemispherical air bag mounting frame 26 is fixedly installed with an inner air bag 262, the outer surface of the outer air bag 261 is in contact with the side surface of the extrusion sheet 242, the inner air bag 262 is arranged on the outer surface of the middle part of the hard adjustment branch pipe 231, the hemispherical air bag mounting frame 26 is internally provided with a cavity, the inner wall bottom of the outer air bag 261 and the inner air bag 262 is fixedly connected with the cavity inner wall of the hemispherical air bag mounting frame 26 through a connecting pipe respectively, the cavity bottom of the hemispherical air bag mounting frame 26 is fixedly installed with a gas guide pipe 263, the lower end of the fixed pipe 21 is fixedly installed with an outer closed hose 25, the lower end of the outer closed hose 25 is fixedly installed with a sealing gasket 251 matched in size with the abdominal cavity drainage branch pipe 234, the outer side surface of the sealing gasket 251 is movably installed with a pressure release sheet 254 above, the inner side surface of the pressure release sheet 254 is bonded with the outer side surface of the connecting ball pipe 233, the inner surface of the outer closed hose 25 is fixedly installed with a ring-shaped air bag mounting frame 252 below, the inner wall of the ring-shaped air bag mounting frame 252 is fixedly connected with the lower end of the gas guide pipe 263, the inner side wall of the ring-shaped air bag mounting frame 252 is fixedly installed with a ring-shaped air bag 253, the inner side wall of the ring-shaped air bag mounting frame 252 and the inner side wall of the ring-shaped air bag 253 are provided with an air pipe, the side surface of the ring-shaped air bag 253 is in contact with the outer side surface of the pressure release sheet 254;

[0039] In this embodiment, the hemispherical air bag mounting frame 26 not only deflects and limits the hollow ball tube below the hard adjustment branch pipe 231 through the limiting sleeve, but also serves as the installation of the outer air bag 261 and the inner air bag 262. When the gasket 32 is pressed to pull the tensioning line 33 to drive the shutter 34 to extrude the adjustment protrusion 241, the extrusion piece 242 will synchronously extrude the inner air bag 262 at the corresponding position. At the same time, the middle tube of the hard adjustment branch pipe 231 is also extruded when it is deflected, and the inner air bag 262 and the outer air bag 261 are both annular air bag rings composed of single small air bags. Each single small air bag is connected to the internal cavity of the hemispherical air bag mounting frame 26 through a branch pipe.

The gas enters the internal cavity of the annular air bag 253 through the air pipe to make it expand, extrude the pressure release piece 254, and make the connecting ball tube 233 be extruded and contracted to a certain extent. It is noted that it is not completely contracted, which can indirectly release the pressure at the drainage site of the abdominal cavity drainage branch pipe 234, reduce the risk of mucosal damage or bleeding, and prevent the drainage hole of the abdominal cavity drainage branch pipe 234 from being blocked. The bottom of the pressure release piece 254 is connected to the sealing gasket 251, and the upper part of the connecting position is provided with a reset spring three. After each adjustment, the reset of the pressure release piece 254 will drive the connecting ball tube 233 to reset and extrude the annular air bag 253. At this time, the hard adjustment branch pipe 231 has been reset, and the air in the internal cavity of the annular air bag 253 will return to the internal cavity of the outer air bag 261 and the inner air bag 262 under the extrusion of the pressure release piece 254 and the pressure. The whole body will not introduce additional air, avoiding the risk of infection. The outer closed hose 25 mainly serves as the function of closing the hard connection branch pipe 232 and the connecting ball tube 233, and the outer closed hose 25 is a soft pipe, which will not limit the movement of the hard connection branch pipe 232 and the connecting ball tube 233. Embodiment four

[0042] Step two, when the abdominal drainage branch pipe 234 needs to be adjusted, the movable adjusting pipe 31 can be rotated by pushing the push pad 32, then the push pad 32 is pressed to pull the tensioning line 33, the tensioning line 33 pulls the gate 34 to push the adjusting block 241, the adjusting block 241 pushes the hollow ball pipe above the hard adjusting branch pipe 231 to the other side, the hollow ball pipe below the hard adjusting branch pipe 231 is deflected by the limiting sleeve of the half-sphere air bag mounting frame 26, the hard connecting branch pipe 232 is deflected to the other side, and the connecting ball pipe 233 and the abdominal drainage branch pipe 234 are adjusted;

[0043] Step three, when the position is reset, the push pad 32 is loosened, the pad 331 is reset by the reset spring two in the movable adjusting pipe 31, the gate 34 is reset, the adjusting block 241 is reset by the reset spring one, and the hard adjusting branch pipe 231 is reset to the initial state for the next adjustment.
