DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-2, a high negative pressure drainage device, comprising a chassis 1. A fixed column 2 is fixedly installed at the top of the chassis 1. A rotating head 3 is rotatably connected to the top of the fixed column 2. An extension plate 4 is fixedly connected to one side of the rotating head 3. Through slots are formed on both sides of the fixed column 2. The extension plate 4 is on the front side of the opposite side of the through slots. A negative pressure gauge 5 is arranged on the top of the extension plate 4. The inner bottom end of the inner wall of the fixed column 2 is fixedly connected with a rotating seat 6. A threaded column 7 is rotatably connected to the inner top wall of the rotating seat 6. A threaded sleeve plate 8 is threadedly connected to the outer wall of the threaded column 7. Sliders are arranged on both sides of the threaded sleeve plate 8. The sliders are slidably connected with the through slots. The top of the threaded column 7 is fixedly connected with the bottom of the rotating head 3. Connecting components 9 are fixedly connected to both sides of the threaded sleeve plate 8. A clamping component 10 is fixedly connected to one side of the connecting component 9. A drainage can 11 is clamped inside the clamping component 10.

[0027] As shown in Figure 3 , the connecting component 9 includes a fixing plate 91. A receiving plate 92 is fixedly connected to one side of the fixing plate 91. A hinge seat 93 is fixedly connected to one side of the receiving plate 92. The hinge seat 93 includes a hinge block, a hinge shaft and a coil spring. The two sides of the hinge shaft are rotatably connected to the hinge seat through the coil spring. A baffle 94 is rotatably connected to one side of the hinge seat 93. A buffer spring 95 is fixedly connected to one side of the baffle 94. The other side of the buffer spring 95 is fixedly connected with a pressing plate 96.

[0028] As shown in Figure 4 , the clamping component 10 includes an outer sleeve ring 101. Slide rods 102 are inserted into both sides of the outer sleeve ring 101. The other ends of the slide rods 102 are fixedly connected with inner clamping plates 103. A return spring 104 is fixedly connected to one side of the inner clamping plate 103. The return spring 104 is located on the outer wall of the slide rod 102, and both sides of the return spring 104 are fixedly connected with the inner clamping plate 103 and the outer sleeve ring 101 respectively.

[0029] During use, the drainage tube connected to the drainage can 11 is inserted into the patient's body. By starting the negative pressure gauge 5, since one end of the negative pressure gauge 5 is in contact with the top of the drainage can 11 through a connecting tube, the negative pressure of the negative pressure gauge 5 will perform a suction pressure treatment on the inside of the connecting tube at this time. At this time, the effusion will be absorbed into the drainage can 11 through the drainage tube. Before that, according to the position of the patient, the height position of the drainage can 11 is adjusted. By rotating the turning head 3, as the turning head 3 rotates, the threaded column 7 is driven to rotate. Since the threaded sleeve plate 8 is threadedly connected to the outer wall of the threaded column 7 and the two sides of the threaded sleeve plate 8 are restricted, the threaded sleeve plate 8 will move up and down until the position of the connecting component 9 is adjusted to an appropriate position. When the drainage can 11 needs to be replaced, the baffle 94 is rotated outward, and then the drainage can 11 is detached from the opening of the clamping component 10. During installation, through the setting of the connecting component 9 and the clamping component 10, by placing the drainage can 11 into the clamping component 10, the stable clamping of the drainage can 11 is achieved, and it can be applicable to drainage cans 11 of different sizes. Through the coil spring inside the hinge seat 93, the baffle 94 can always rotate towards the side of the drainage can 11, so that the pressing plate 96 can be in contact with the outer side of the drainage can 11, thereby achieving a full-surround contact with the drainage can 11 and preventing the accidental detachment of the drainage can 11.

[0030] In summary, for this high negative pressure drainage device, through the setting of the connecting component 9 and the clamping component 10, by placing the drainage can 11 into the clamping component 10, the stable clamping of the drainage can 11 is achieved, and it can be applicable to drainage cans 11 of different sizes. Through the coil spring inside the hinge seat 93, the baffle 94 can always rotate towards the side of the drainage can 11, so that the pressing plate 96 can be in contact with the outer side of the drainage can 11, thereby achieving a full-surround contact with the drainage can 11 and preventing the accidental detachment of the drainage can 11.

[0031] By rotating the turning head 3, as the turning head 3 rotates, the threaded column 7 is driven to rotate. Since the threaded sleeve plate 8 is threadedly connected to the outer wall of the threaded column 7 and the two sides of the threaded sleeve plate 8 are restricted, the threaded sleeve plate 8 will move up and down until the position of the connecting component 9 is adjusted to an appropriate position, which is convenient for the use of the drainage can 11. At the same time, this method improves the stability of the drainage can 11.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
