As shown in fig. 1, a drainage assembly for drainage is inserted into the waste liquid barrel 2 from the top, and a drainage pipe 15 is connected to one side of the bottom of the waste liquid barrel 2. The liquid drainage assembly comprises a push-pull rod 16 vertically penetrating through the top of the waste liquid barrel 2 and a squeezing plate 17, wherein the squeezing plate 17 is horizontally arranged and fixed at the bottom end of the push-pull rod 16. Waste liquid bucket 2 is cylindric structure, stripper plate 17 is the disc structure with 2 internal diameter adaptations of waste liquid bucket, and this stripper plate 17 and waste liquid bucket 2 sliding connection. An elastic resetting piece 18 for resetting the extrusion plate 17 upwards is sleeved on the push-pull rod 16, one end of the elastic resetting piece 18 is fixedly connected with the top of the waste liquid barrel 2, the other end of the elastic resetting piece 18 is fixedly connected with the extrusion plate 17, and a handle 19 is fixed at the top end of the push-pull rod 16.

Work as after the waste liquid in the waste liquid bucket 2 reaches a certain amount, medical personnel can adopt the clip centre gripping on first connecting pipe 3 or second connecting pipe 6 this moment to prevent the waste liquid in the waste liquid bucket 2 through the refluence of second connecting pipe 6, later medical personnel hold handle 19 with the hand and push-and-pull rod 16 push down, this in-process the stripper plate 17 will extrude the waste liquid in the waste liquid bucket 2, thereby make the waste liquid follow discharge in the fluid-discharge tube 15, this kind of mode of setting can further conveniently be with the waste liquid discharge in the waste liquid bucket 2, improves flowing back efficiency, after the flowing back is accomplished, elasticity reset 18 will drive stripper plate 17 and push-and-pull rod 16 upwards resets, and this elasticity reset 18 is spring structure.

The working principle is as follows:

the medical staff butt joints the elastic pad 5 on the connecting plate 4 at the end part of the first connecting pipe 3 with the elastic pad 5 on the connecting plate 4 at the end part of the second connecting pipe 6, and the inserting pipe 12 is inserted in the inserting hole 14, at this time, the first connecting pipe 3 and the second connecting pipe 6 are in a conducting state.

Later medical personnel with the help of the centre gripping subassembly seals the butt to two elastic cushions 5, and the centre gripping subassembly closely ground pressure is in the same place two elastic cushions 5 this moment, guarantees to follow the waste liquid that flows through in first connecting pipe 3 and the second connecting pipe 6 and can not follow two elastic cushions 5 between flow, thereby has guaranteed the leakproofness of being connected between first connecting pipe 3 and the second connecting pipe 6, thereby prevents the weeping, specifically, medical personnel grip butt board 10 and rotatory butt board 10, butt board 10 drives annular plate 8 precession through gripping a section of thick bamboo 9 this moment, and it is inseparable to cooperate two elastic cushions 5 centre gripping until

annular plate

8 and 7 tip of screw thread section of thick bamboo, butt board 10 this moment with the tip butt of screw thread section of thick bamboo 7.

Then when the body 1 works, the waste liquid displaced from the body 1 sequentially flows through the first connecting pipe 3 and the second connecting pipe 6 and enters the waste liquid barrel 2, and when the waste liquid in the waste liquid barrel 2 reaches a certain amount, the medical staff cleans the waste liquid in the waste liquid barrel 2, specifically, the medical staff can clamp the first connecting pipe 3 or the second connecting pipe 6 by using a clamp, so that the waste liquid in the waste liquid barrel 2 is prevented from flowing backwards through the second connecting pipe 6, and then the medical staff holds the handle 19 to press the push-pull rod 16 by hand, in the process, the extrusion plate 17 extrudes the waste liquid in the waste liquid barrel 2, so that the waste liquid is discharged from the liquid discharge pipe 15, and then the elastic resetting piece 18 drives the extrusion plate 17 and the push-pull rod 16 to reset upwards.

This kind of setting mode can enough reduce medical personnel's work load, and this kind of setting mode can prevent again that the waste liquid from following body 1 to the in-process weeping that flows through between waste liquid bucket 2.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
