Description

Technical Field

[0001] This utility model relates to the field of catheter fixation technology, and in particular to a catheter fixation device for hemodialysis in nephrology. Background Technology

[0002] Hemodialysis is a treatment that involves draining blood from the body into an external dialyzer for purification before returning it to the body. During dialysis, at least two catheters are used to connect the blood vessels and the dialyzer, forming an extracorporeal blood circulation loop. Dialysis is a long process that requires stability; therefore, the catheters must be securely fixed to prevent accidental dislodgement or displacement, which could disrupt the dialysis process or even cause unnecessary harm to the patient.

[0003] Existing catheter fixation devices typically use two clamps to secure the catheter, which are fixed at the edge of the bed. However, because different patients have different positions, the direction and distribution of the catheters also vary. Existing clamps cannot adapt well to the direction and distribution of the catheters, which can easily cause problems such as catheter bending, making dialysis work inconvenient and difficult to adjust.

[0004] The existing fixation techniques cannot adapt to the routing and distribution of catheters and need to be addressed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fixation device for hemodialysis catheters in nephrology, which addresses the above-mentioned technical deficiencies and solves the problem that existing fixation techniques cannot adapt to the direction and distribution of catheters.

[0006] The technical solution adopted by this utility model is: to provide a nephrology hemodialysis catheter fixation device, including a vertically arranged support, and further comprising:

[0007] A mounting plate is horizontally disposed at the upper end of the bracket, and the mounting plate has a plurality of spaced threaded holes;

[0008] A positioning frame is provided, and the positioning frame has a through hole. A connecting bolt passes through the through hole and is threadedly connected to the threaded hole to fix the positioning frame. The positioning frame is rotatably disposed relative to the mounting plate. After the connecting bolt is tightened, the positioning frame is fixed on the mounting plate.

[0009] The base plate is hinged to the positioning frame;

[0010] A cover plate is detachably mounted on the base plate, and the cover plate and the base plate are used to clamp the conduit.

[0011] To further optimize this technical solution, each positioning frame has two opposing support frames, and each support frame has a base plate hinged to its upper end. The through hole is located between the two support frames.

[0012] To further optimize this technical solution, the side of the base plate has a sliding groove, the side of the cover plate is slidably inserted into the sliding groove, and a limiting channel is formed between the cover plate and the base plate, which is sleeved outside the guide tube.

[0013] Further optimizing this technical solution, the bracket includes a movable rod and a fixed rod, the movable rod being vertically mounted on the fixed rod, and the mounting plate being horizontally mounted on the upper end of the movable rod; it also includes:

[0014] The support plate is raised and lowered relative to the mounting plate and is located below the mounting plate;

[0015] The locking bolt passes through the support plate and is threaded into one of the threaded holes.

[0016] To further optimize this technical solution, one side of the pallet is slidably sleeved on the moving rod, and the upper end of the other side has an upwardly protruding upper edge.

[0017] To further optimize this technical solution, the lower end of the bracket has a base plate, and the fixing rod is located on one side of the upper end of the base plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. An appropriate number of positioning brackets can be selected for installation on the mounting plate as needed, usually two. The conduit is fixed by clamping the base plate and cover plate. The positions of the positioning brackets on the mounting plate are adjustable to adapt to the spacing distribution of the conduit.

[0020] 2. During installation, the positioning frame can be adjusted horizontally relative to the mounting plate so that the direction of the base plate and cover plate is parallel to the direction of the conduit, reducing the offset of the conduit and reducing the conduit bending problem. At the same time, the base plate is hinged to the positioning frame and can be rotated up and down to adapt to the conduit routing, reducing the conduit bending problem. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figure 1-3 As shown, a hemodialysis catheter fixing device for nephrology includes a vertically arranged support 1, and further includes: a mounting plate 2, horizontally arranged at the upper end of the support 1, the mounting plate 2 having a plurality of spaced threaded holes 201; a positioning frame 3, having a plurality of through holes 301, a connecting bolt 304 passing through the through holes 301 and threadedly connected to the threaded holes 201 for fixing the positioning frame 3, the positioning frame 3 being rotatably arranged relative to the mounting plate 2, and after the connecting bolt 304 is tightened, the positioning frame 3 is fixed on the mounting plate 2; a base plate 4, hingedly arranged on the positioning frame 3; and a cover plate 5, detachably arranged on the base plate 4, the cover plate 5 and the base plate 4 being used to clamp the catheter.

[0030] When in use, patients lying on the bed may have different positions and heights, resulting in variations in the catheter's path. The positioning frame 3 is fixed to the mounting plate 2, and can be installed at a suitable location using the threaded hole 201. The connecting bolt 304 passes through the positioning frame 3 and locks it onto the mounting plate 2. Before locking, the positioning frame 3 can rotate horizontally to align the base plate 4 and cover plate 5 with the catheter's path, reducing catheter bending or pulling and minimizing catheter movement. The base plate 4 can rotate vertically to better accommodate the catheter's path. The lower part of the base plate 4 is hinged to the positioning frame 3 via a pivot and can be fixed at an angle using conventional methods such as bolt tightening. The catheter is placed on the top of the base plate 4, and the cover plate 5 is fastened to the base plate 4 to clamp and secure the catheter.

[0031] Furthermore, each positioning frame 3 has two opposing support frames 302, and a base plate 4 is hinged to the upper end of each support frame 302, with a through hole 301 located between the two support frames 302.

[0032] In use, the positioning frame 3 can have a tubular structure in the middle. A connecting bolt 304 passes through the tubular structure and connects to the mounting plate 2. Support frames 302 are located on both sides of the outer side of the tubular structure. Two base plates 4 are hinged to the positioning frame 3, allowing for two usage methods. In the first usage, the two base plates 4 on each positioning frame 3 are used to fix two spaced positions of the same conduit, resulting in a more secure two-point positioning. In the second usage, when there are many conduits to be fixed, each base plate 4 can fix one conduit. Multiple positioning frames 3 can also be installed on the mounting plate 2, allowing the selection of the number of positioning frames 3 to fix multiple conduits simultaneously.

[0033] Furthermore, the bottom plate 4 has a sliding groove 401 on its side, and the side of the cover plate 5 is slidably inserted into the sliding groove 401. The cover plate 5 and the bottom plate 4 form a limiting channel 6, which is sleeved outside the guide tube.

[0034] In use, the cover plate 5 and the base plate 4 are detachably connected, and conventional structures such as plug-in connection, locking connection, and snap-fit ​​connection can be used. Recessed grooves 401 can be provided on both sides of the base plate 4. The side of the cover plate 5 is slidably inserted into the groove 401, with the cover plate 5 positioned above the base plate 4. The opposing surfaces of the cover plate 5 and the base plate 4 can have semi-circular grooves. After the cover plate 5 and the base plate 4 are joined, the grooves form a limiting channel 6, and the guide tube is clamped and fixed within the limiting channel 6.

[0035] Furthermore, the bracket 1 includes a movable rod 101 and a fixed rod 102. The movable rod 101 is elliptically mounted on the fixed rod 102, and the mounting plate 2 is laterally mounted on the upper end of the movable rod 101. It also includes a support plate 7, which is elliptically mounted relative to the mounting plate 2 and located below the mounting plate 2; and a locking bolt 702, which passes through the support plate 7 and is threadedly connected to one of the threaded holes 201. One side of the support plate 7 is slidably fitted onto the movable rod 101, and the upper end of the other side has an upwardly protruding upper edge 701.

[0036] In use, the height of the mounting plate 2 can be adjusted by raising and lowering the movable rod 101. The mounting plate 2 can abut against the upper side of the edge of the hospital bed, and the support plate 7 abuts against the lower side of the edge of the hospital bed. The mounting plate 2 and the support plate 7 are connected by locking bolts 702 to form a clamping structure, which can make the bracket 1 more stably fixed next to the hospital bed. The raising and lowering of the movable rod 101 is set on the fixed rod 102, and the positioning after raising and lowering can be achieved by conventional locking structure.

[0037] One side of the support plate 7 is slidably sleeved on the moving rod 101, making the lifting and lowering of the support plate 7 more stable. It also forms a clamping structure with the mounting plate 2, which is more stable. At the same time, the support plate 7 has an upward protrusion on the other side near the hospital bed, which can be used to hook the inner edge of the hospital bed, making the positioning more stable and reducing the risk of dislodgement.

[0038] Furthermore, the lower end of the bracket 1 has a base plate 4, and the fixing rod 102 is located on one side of the upper end of the base plate 4.

[0039] In use, the bracket 1 consists of a base plate 4, a fixing rod 102, and a moving rod 101 from bottom to top. Normally, the fixing rod 102 is located in the middle of the base plate 4. However, in this application, the fixing rod 102 is positioned eccentrically, near the edge of the upper part of the base plate 4. This causes the base plate 4 to bulge outwards to one side relative to the fixing rod 102, and it is arranged on the same side as the support plate 7. This structure helps to conceal the base plate 4 and the area under the bed, reducing exposure and lowering the risk of being kicked, thus improving stability and safety. Combined with the support plate 7 and the installed clamping structure, the overall structure is stable and not easily tipped over.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
