Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a drain pot cover for hemodialysis equipment. Background Art
[0002] At present, the intubation port of the drainage pot of some models of hemodialysis equipment is open and has no special cover. Since this type of open drainage pot needs to be cleaned, the opening is much larger than the outer diameter of the cannula, that is, the drainage pot is in an open and exposed state. Due to improper use by the patient and the overflow of aerosols and hydrosols splashed during flushing, bacterial cross-infection may occur, causing discomfort to the patient and causing a series of adverse reactions. Summary of the Invention
[0003] The purpose of the utility model is to provide a hemodialysis equipment drainage pot cover with a simple structure, easy operation, good barrier effect, and detachable cleaning, which can effectively prevent bacterial infection that may be caused by splashing aerosols and hydrosols from the drainage pot.
[0004] In the present invention, the hemodialysis equipment is equipped with an extracorporeal blood circulation circuit provided with a drainage tube connected to a drainage pot. The provided hemodialysis equipment drainage pot cover comprises a cover base, a rotatable cover and a slide.
[0005] The cover base is used to cover the mouth of the drain pot, with an opening in the center and a ring structure; an axis hole is provided at the side of the cover base;
[0006] The rotatable cover is arranged on the cover base and can seal and cover the central opening of the cover base; an axis hole is provided on the side of the rotatable cover, and the axis hole of the cover base and the axis hole of the rotatable cover are rotatably connected together through a pin shaft, so that the rotatable cover can be rotated horizontally to open / close the central opening of the cover base;
[0007] The center of the rotatable cover is provided with an insertion hole for the drainage pipe to pass through, and the rotatable cover is provided with a slide groove at the edge of the insertion hole. The slide is connected to the rotatable cover through the slide groove and can slide back and forth along the slide groove to loosen / clamp the drainage pipe in the insertion hole.
[0008] In the present invention, a slide insertion hole is also provided in the center of the slide for the drainage pipe to pass through, which corresponds to the insertion hole of the rotatable cover plate. After the drainage pipe passes through the insertion hole and the slide insertion hole at the same time, the position of the slide is adjusted, that is, the overlapping area between the insertion hole and the slide insertion hole is adjusted to adjust the loosening / clamping of the drainage pipe.
[0009] In the present invention, a limit bar is provided on the rotatable cover plate. When the slide is inserted into the slide groove, the limit bar can resist the insertion end of the slide, restricting the slide from continuing to slide, causing the insertion hole and the slide insertion hole to be completely misaligned, thereby preventing the drainage pipe from being clamped.
[0010] In the present invention, a semicircular notch is further provided on the edge of the tube insertion hole of the rotatable cover plate, and a semicircular notch is also provided on the opposite edge of the corresponding slide tube insertion hole, and the diameter of the semicircular notch is smaller than the diameter of the tube insertion hole; since the tube insertion hole is a soft tube, the tube insertion hole and the slide tube insertion hole can retain the space formed by the docking of the two semicircular cuts in the staggered state to prevent the drainage pipe from being clamped.
[0011] In the present invention, the slide groove is a rectangular frame structure, at least one pair of opposite surfaces is a hollow frame structure, and is arranged above the rotatable cover plate.
[0012] In the present invention, the size of the cover base is determined according to the size of the existing drainage pot mouth and can be of different specifications. The insertion hole and the slide insertion hole can also be designed to match the size of the dedicated drainage pipe of various models of dialysis equipment.
[0013] When the lid is closed, the cover plate base is locked on the mouth of the drainage pot, and the rotatable cover plate is kept covering the opening of the cover plate base. The insertion hole of the rotatable cover plate and the sliding tube insertion hole of the slide groove form a socket space, and the drainage tube on the hemodialysis equipment can pass through the socket space and enter the drainage pot; when the insertion hole and the sliding tube insertion hole completely overlap, the socket space is maximized, ensuring that the drainage tube can pass through smoothly; after the drainage tube position is set, the slide is pushed to reduce the socket space, so that the insertion hole and the edge of the sliding tube insertion hole squeeze the drainage tube, and the limiting strips and / or the semicircular notches of the docking insertion hole and the sliding tube insertion hole ensure that the insertion hole and the sliding tube insertion hole will not squeeze and close the drainage tube, ensuring smooth drainage during hemodialysis; and the mouth of the drainage pot is closed by the cover plate, which greatly reduces the risk of aerosol and hydrosol overflow infection under splashing, and also prevents foreign matter from falling. When the drainage pot needs to be flushed at the bedside of a miscellaneous patient, there is no need to remove the entire cover. You only need to push the slide to loosen the drainage tube and take it out, rotate the rotatable cover to expose the larger central opening of the cover base, and then you can flush.
[0014] The utility model has the advantages of simple structure, low cost and convenient operation. In clinical application, it can greatly reduce any adverse reactions caused by bacteria in aerosols and hydrosols and reduce the occurrence of nosocomial infections. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] For the BC-110N (B) type hemodialysis equipment drainage pot, the hemodialysis equipment is equipped with a drainage tube on the extracorporeal blood circulation path, which is connected to the drainage pot, including a cover base 1, a rotatable cover 2, a slide 3, a slide 4 and a pin 5, and is made of medical plastic material.
[0020] The cover base 1 is used to cover the mouth of the drain pot 13. The cover base 1 is a circular plane with an opening in the center, presenting a ring structure, such as Figure 1 As shown; the existing drainage pot 13 has a convex edge around the pot mouth, and the outer edge of the cover base 1 is surrounded by a circle of inner buckle slots 12 perpendicular to the circular plane, which can be clamped on the edge of the pot mouth of the drainage pot 13 by plastic deformation; for specific structure, refer to Figure 3 As shown, the shape of the inward buckle slot 12 can be designed according to the shape of the mouth of each type of drainage pot, which is a conventional technical means.
[0021] A local raised block 6 is provided at a local side edge of the cover base 1, and an axis hole 7 is provided on the local raised block 6;
[0022] The rotatable cover plate 2 is a circular cover plate, which is arranged on the cover plate base 1 and can seal and cover the central opening of the cover plate base 1; the local raised piece on the edge of the rotatable cover plate 2 corresponds to the local raised block 6 of the cover plate base, and the local raised piece is also provided with an axial hole 7. The axial hole 7 of the cover plate base 1 and the axial hole 7 of the rotatable cover plate 2 are rotatably connected together through a pin shaft 5, so that the rotatable cover plate 2 can rotate horizontally to open / close the central opening of the cover plate base 1.
[0023] The center of the rotatable cover plate 2 is provided with an insertion hole 8 for the drainage pipe to pass through only. The inner diameter of the insertion hole 8 can be set to 10-14 mm. The outer diameter of the drainage pipe of this model is about 6 mm. The upper surface of the rotatable cover plate 2 is provided with a rectangular frame structure as a slide groove 4 at the position of the insertion hole 2. A pair of opposite surfaces are hollow frame structures. The slide 3 is connected to the rotatable cover plate 2 through the slide groove 4, that is, the slide 3 can be inserted into the space formed between the rectangular frame and the rotatable cover plate 2, and can slide back and forth along the slide groove 4; the end of the slide 3 inserted is the insertion end, and the other end is the pushing end, which is provided with a raised rib to increase the pushing feel; Figure 1 、 Figure 3 shown.
[0024] The center of the slide 3 is also provided with a slide insertion hole 9 for the drainage pipe to pass through, which corresponds to the insertion hole 8 of the rotatable cover 2. The inner diameter of the slide insertion hole 9 is also larger than the outer diameter of the drainage pipe and can be set to 10-14 mm. After the drainage pipe passes through the insertion hole 8 and the slide insertion hole 9 at the same time, the position of the slide 3 is adjusted, that is, the overlapping area between the insertion hole 8 and the slide insertion hole 9 is adjusted, so as to adjust the loosening / clamping of the drainage pipe; Figure 2 shown.
[0025] The rotatable cover plate 2 may further be provided with a limit strip 10 with a raised surface. When the slide 3 is inserted into the slide groove 4, the limit strip 10 can abut against the insertion end of the slide 3, limiting the slide 3 from sliding further, thereby preventing the insertion hole 8 and the slide insertion hole 9 from being completely misaligned, thereby preventing the drainage pipe from being clamped.
[0026] In addition, a semicircular notch 11 is provided on the edge of the insertion hole 8 of the rotatable cover plate 2, and a semicircular notch 11 is also provided on the opposite edge of the corresponding slide insertion hole 9. The diameter of the semicircular notch 11 is smaller than the diameter of the insertion hole 8; since the drainage pipe is a soft pipe, the insertion hole 8 and the slide insertion hole 9 can retain the space formed by the docking of the two semicircular notches 11 in the staggered state to prevent the drainage pipe from being clamped; Figure 2 shown.
[0027] Two limiting modes can be selected either one or used simultaneously to further prevent the drain pipe from being pinched.
[0028] In the present invention, the size of the cover base is determined according to the size of the existing drainage pot mouth and can be of different specifications. The insertion hole and the slide insertion hole can also be designed to match the size of the dedicated drainage pipe of various models of dialysis equipment.
[0029] When the lid is closed, the cover plate base is locked on the mouth of the drainage pot, and the rotatable cover plate is kept covering the opening of the cover plate base. The insertion hole of the rotatable cover plate and the sliding tube insertion hole of the slide groove intersect to form a socket space, and the drainage tube on the hemodialysis equipment can pass through the socket space into the drainage pot; when the insertion hole and the sliding tube insertion hole completely overlap, the socket space is maximized, ensuring that the drainage tube can pass through smoothly; after the drainage tube position is set, the slide is pushed to reduce the socket space, so that the insertion hole and the edge of the sliding tube insertion hole squeeze the drainage tube, and the limiting strips and / or the semicircular notches of the docking insertion hole and the sliding tube insertion hole ensure that the insertion hole and the sliding tube insertion hole will not squeeze and close the drainage tube, ensuring smooth drainage during hemodialysis; and the mouth of the drainage pot is closed by the cover plate, which greatly reduces the risk of aerosol and hydrosol overflow infection under splashing, and also prevents foreign matter from falling. When the drainage pot needs to be flushed at the bedside of a miscellaneous patient, there is no need to remove the entire cover. You only need to push the slide to loosen the drainage tube and take it out, rotate the rotatable cover to expose the larger central opening of the cover base, and then you can flush.
[0030] The utility model is applied clinically, has low cost, is easy to clean, can greatly reduce any adverse reactions caused by bacteria present in aerosols and hydrosols, and reduces the occurrence of nosocomial infections.
