[0039] See also Figure 1 , Figure 1 The utility model provides a schematic diagram of a three-chamber chest closed drainage device, which is a schematic diagram of the three-chamber chest closed drainage device in an unused state.
[0040] like Figure 1 As shown, the utility model provides a three-chamber chest closed drainage device, comprising a three-chamber drainage bottle 10 and a drainage stand 20 for placing the three-chamber drainage bottle 10. A support leg 30 is rotatably provided on the bottom surface of the drainage stand 20, and the support leg 30 is used to improve the stability of the three-chamber chest closed drainage device when it is placed on the ground for use, and to prevent the three-chamber chest closed drainage device from tipping over. A hanging bracket 40 is provided at the upper end of the drainage stand 20, and the hanging bracket 40 is used to hang the three-chamber chest closed drainage device on a bed frame for use.
[0041] Figure 2 Schematic diagram of the drainage frame in the utility model, such as Figure 2 As shown, the drainage rack 20 includes a base 21 and a fence 22 disposed above the base 21, and two opposite sides of the base 21 and the fence 22 are connected as a whole through a connecting plate 23. An opening for disassembling and assembling the three-chamber drainage bottle 10 is provided on the top surface of the fence 22, so that the drainage rack 20 can be reused, reducing the use cost.
[0042] In this embodiment, the legs 30 are in the shape of strip plates, and one end of the four legs 30 is respectively rotated and arranged at the four corners of the bottom surface of the drain rack 20. In the folded state, the two legs 30 arranged along the length direction of the base 21 are arranged with their free ends facing each other. Compared with the traditional design of arranging the two legs in the middle of the bottom surface of the drain rack 20, Figure 6 In the solution of the utility model shown, the unfolded length of the two legs 30 is much greater than that of the traditional design, and the distance between the legs is larger, so that the drainage rack 20 has higher stability when placed on the ground.
[0043] A first rotating shaft 24 is respectively disposed on two opposite sides in the length direction of the fence 22 , and the hanger 40 is rotatably disposed on the first rotating shaft 24 .
[0044] like Figure 3As shown, the hanger 40 includes a connecting frame 41 and a hook 42 rotatably arranged on the connecting frame 41. The connecting frame 41 is door-shaped, and the lower ends of the two side walls are rotatably connected to the first rotating shaft 24 respectively. The lower end of the hook 42 is rotatably arranged on the top crossbeam of the connecting frame 41, and a baffle 43 is rotatably arranged on the side wall of the hook 42. The free end of the baffle 43 is stuck in the open end of the hook 42, for example, a block is set on the inner wall of the open end of the hook 42. When in use, the baffle 43 is rotated upward to form an opening, and the hook 42 is opened. After the bed frame is hung, the baffle 43 is rotated downward and stuck on the open end of the hook 42. This design can prevent the hook from loosening during the movement of the bed. In particular, in the present application scheme, the hanger 40 has two degrees of freedom in two directions. When the hanging distance in the length direction on the bed frame is small, it can also be hung by rotating around the first rotating shaft 24.
[0045] In the present invention, the middle part of the hook 42 and the middle part of the baffle 43 can be designed to be pull-out, so as to adjust the width of the hook 42 according to the thickness of the bed frame crossbeam, thereby adapting to various bed frames. The pull-out matching part can be provided with a convex point for matching and limiting.
[0046] like Figure 4 As shown, in the utility model, the three-chamber drainage bottle 10 includes a fluid collection bottle 11, a water seal bottle 12 and an adjusting bottle 13. The covers of the fluid collection bottle 11, the water seal bottle 12 and the adjusting bottle 13 are all provided with connecting tubes 14. The fluid collection bottle 11 and the water seal bottle 12 are connected by a drainage tube 15. The two ends of the drainage tube 15 are respectively inserted into the connecting tubes 14 of the fluid collection bottle 11 and the water seal bottle 12, and are clamped and fixed by buckles 16. Similarly, the drainage tube connected to the patient can also be clamped and fixed to the fluid collection bottle 11 by the buckle 16. Figure 4 In the embodiment, the buckle 16 is in an unfastened state.
[0047] like Figure 5 As shown, the buckle 16 includes an annular snap ring 161 with an opening, and the first and second snap-fitting parts 162 and 163 are respectively provided at both ends of the opening of the annular snap ring 161. A slot 164 is provided on the side of the first snap-fitting part 162 facing the second snap-fitting part 163, and a first snap-fitting tooth is provided on the inner wall of the slot 164. A latch 165 matching the slot 164 is provided on the second snap-fitting part 163, and a second snap-fitting tooth matching the first snap-fitting tooth is provided on the latch 165. The annular snap ring 161 is elastic. When in use, the annular snap ring 161 is sleeved on the drainage tube 15, and then the latch 165 is inserted into the slot 164 to clamp and fix the drainage tube 15 and the connecting tube 14. In this way, the drainage tube 15 is reliably connected, and even if the drainage tube 15 is pulled up by mistake, it will not cause the drainage tube 15 to loosen and leak. A convex ridge 166 can also be provided on the inner wall of the annular snap ring 161 to increase the clamping force.
[0048] like Figure 1 , Figure 2As shown, in the present invention, a strip of Velcro 50 is provided on the outer side of the base 21 and the fence 22 on the same side, for example, nylon Velcro, and the middle part of the back is fixed to the outer side of the base 21 and the fence 22. With this structural design, when the patient uses the rehabilitation push rod for activities, the drainage bottle can be placed on the base of the rehabilitation push rod, and the drainage bottle can be tied and fixed to the vertical pole of the rehabilitation push rod through the Velcro 50, which is convenient to carry and will not fall over or fall off, which is convenient for the patient to carry when performing rehabilitation activities.
[0049] The utility model can be used in three ways.
[0050] The first way of using is to use it on the ground, such as Figure 7 As shown, the four legs 30 are rotated outwards respectively and can be rotated to a perpendicular state to the side of the base, so as to improve stability and prevent the base from being accidentally kicked and tipped over.
[0051] The second way to use it is to hang it on the bed frame, such as Figure 8 As shown, the hanger 40 is rotated upward, and then the hook is opened. After hanging it on the bed frame, the hook is closed to prevent accidental falling off.
[0052] The third way to use it is to use it on the go. Figure 8 As shown, the three-chamber chest closed drainage device is placed on the base 61 of the rehabilitation push rod, and the drainage frame 20 is fixed to the vertical pole 62 of the rehabilitation push rod by the Velcro 50. In this way, the patient can carry the drainage bottle for activities without worrying about the drainage bottle tipping over, which is convenient to use.
[0053] Based on the description of the above specific embodiments, the three-chamber chest closed drainage device provided by the present invention has the following advantages compared with the prior art:
[0054] First, the four corners of the bottom surface of the base of the drainage rack are respectively rotatably provided with supporting feet. Compared with the traditional design in which two supporting feet are arranged in the middle of the bottom surface of the drainage rack, the expanded length of the two supporting feet in the present utility model is much greater than the traditional design, and the distance between the supporting feet is larger, so that the drainage rack is more stable when placed on the ground.
[0055] Secondly, the hanging bracket has two degrees of freedom in two directions. When the hanging distance in the length direction of the bed frame is small, the hanging bracket can also be realized by rotating around the first rotating axis.
[0056] Third, the drainage tube and the connecting tube are fastened and fixed by means of a buckle, so even if the drainage tube is pulled up by mistake, it will not cause the drainage tube to loosen and leak.
[0057] Fourthly, a baffle is rotatably provided on the side wall of the hook of the hanger, and the free end of the baffle is stuck in the open end of the hook, which can prevent the hook from loosening during the movement of the bed.
[0058] Finally, it should be noted that the terms "comprises", "includes" or any other variants thereof as used herein are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
[0059] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware of the structural changes made under the inspiration of the present invention. All technical solutions that are the same or similar to the present invention fall within the protection scope of the present invention.
