[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 6 It is given, including a main body shell 1 with upper and lower axial directions, an adjusting plate 2 is coaxially rotatably connected inside the main body shell 1, a plurality of through holes 3 are opened on the adjusting plate 2 which are evenly distributed along its circumferential direction and penetrate up and down, and the diameters of the plurality of through holes 3 decrease in sequence clockwise from the leftmost end, a drainage tube 4 is disassembled and connected to the upper end of the main body shell 1, and a connecting tube 5 is disassembled and connected to the lower end of the main body shell 1, and a drainage bag 6 is provided at the lower end of the connecting tube 5.

[0014] In order to facilitate the rotation of the adjustment plate 2, the main shell 1 is provided with an arc-shaped sliding groove 7, and the right end of the adjustment plate 2 is provided with a left-right axial circular groove 8, in which a pull column 9 is coaxially slidably connected, and a shift block 10 is provided at the right end of the pull column 9.

[0015] In order to facilitate the fixing and limiting of the adjustment plate 2, the main body shell 1 is provided with a plurality of limiting holes 11 located above the slide slots 7 and corresponding to the plurality of through holes 3 one by one, and the left end of the shift block 10 is provided with a limiting column 12 which can be inserted into the limiting hole 11.

[0016] In order to facilitate the reset of the shifting block 10 , the left end of the pulling column 9 is connected to the adjusting plate 2 via a tension spring 13 .

[0017] In order to facilitate the disassembly and connection between the drainage tube 4 and the connecting tube 5 and the main shell 1, the upper and lower ends of the main shell 1 are respectively provided with upper and lower axial connecting tubes 14 that can be connected with the through hole 3, and the lower end of the drainage tube 4 and the upper end of the connecting tube 5 are respectively provided with joint tubes 15 that are detachably connected to the connecting tube 14.

[0018] In order to facilitate identification by medical personnel, a plurality of indicator plates 16 corresponding to the through holes 3 are provided at the upper end of the main shell 1 , and an indicator mark 17 pointing to the indicator plates 16 is provided at the upper end of the dial block 10 .

[0019] In order to facilitate hanging the main body shell 1, a hook 18 is provided at the left end of the main body shell 1.

[0020] When the utility model is in use, the hook 18 is first hung on the bed, and then the drainage bag 6 is fixed under the bed, and the upper end of the drainage tube 4 is inserted into the patient's body. Due to the attraction of gravity or negative pressure, the accumulated fluid in the patient's body flows into the drainage bag 6 through the drainage tube 4, the joint tube 15, the connecting tube 14, the through hole 3, etc., so as to achieve the purpose of draining the accumulated fluid. At this time, the largest diameter of the multiple through holes 3 is connected to the two connecting tubes 14, so the most liquid flows in the same time, so the drainage speed is the highest. When it is necessary to adjust the drainage speed and reduce the drainage speed, the shift block 10 is pulled to the right at this time, and the shift block 10 drives the pull column 9 to move to the right in the circular groove 8 and stretches the tension spring 13 to the right, and at the same time drives the limit column 12 to move to the right. After moving to the right for a distance, the limit column 12 is pulled out from the corresponding limit hole 11, thereby releasing the fixed limit of the adjustment plate 2;

[0021] Then rotate the shift block 10 counterclockwise, the shift block 10 drives the adjusting plate 2 to rotate counterclockwise, and the adjusting plate 2 drives the through hole 3 thereon to rotate counterclockwise. After rotating a certain angle, when the through hole 3 with a smaller diameter is coaxially connected with the upper and lower connecting pipes 14, the shift block 10 is released at this time. Due to the inward restoring force of the tension spring 13, the limit column 12 is driven to slide inward, slide inward for a distance and insert into the corresponding limit hole 11 to achieve fixed limit. Since the diameter of the connected through hole 3 is smaller than the diameter of the first through hole 3 at this time, the amount of accumulated fluid flowing through in the same time is smaller, which serves the purpose of reducing the drainage speed. When the drainage speed needs to be reduced again, pull the shift block 10 to the right and rotate it again, and the medical staff can adjust the corresponding flow rate according to the indication of the indicator plate 16.

[0022] Compared with the prior art, the beneficial effects of the utility model are: the main body shell, adjustment plate, through holes, etc. can be used to drain the accumulated fluid in the patient's body and accelerate the patient's recovery. At the same time, the drainage speed can be adjusted according to the conditions of different patients during drainage. The operation is simple, time-saving and labor-saving. The hook is provided to facilitate the hanging of the main body shell. This structure is simple, novel in conception, easy to use and highly practical.
