[0015] Using the aforementioned dialysis catheter fixing device, specifically during the fixing process of the dialysis catheter, the catheter clamping assembly is assembled on the top surface of the flexible substrate. This allows the catheter clamping assembly to be quickly and securely fixed to the patient's skin surface by adhering it to the adhesive film covering the bottom surface of the flexible substrate. Furthermore, the adhesive tape on both sides of the flexible substrate adheres to the patient's skin surface, further securing the catheter clamping assembly. This facilitates the fixing of the Y-shaped bifurcation of the dialysis catheter using the clamping assembly, improving the fixing effect and simplifying the fixing operation. Specifically, the clamping assembly includes a lower fixing block and an upper movable block. Both the fixing and movable blocks have corresponding clamping grooves on their opposite end faces, allowing them to close together. The clamping mechanism allows the clamping grooves to close together. The elastic liner tightly presses and fixes the Y-shaped bifurcation of the dialysis tubing, achieving both rapid and stable fixation while ensuring the independence of the Y-shaped bifurcation points. Specifically, during the assembly and disassembly of the movable and fixed pressure blocks, the connecting rod of the fixed pressure block passes through the mating hole of the movable pressure block, and a locking ring is added. This allows the movable pressure block to be quickly assembled and fixed to the top of the fixed pressure block, and only the locking ring needs to be removed. After the ring is closed, the connecting rod and the mating hole can be disengaged, and the movable pressure block can be removed from the top of the fixed pressure block. The combination and disassembly of the movable pressure block on the top of the fixed pressure block is simple and easy to implement. It is convenient to quickly assemble the movable pressure block on the top of the fixed pressure block to fix the Y-shaped bifurcation position of the dialysis tube and maintain the fixed state of the dialysis tube. At the same time, it is convenient to remove the movable pressure block from the top of the fixed pressure block to remove the Y-shaped bifurcation position of the dialysis tube and release the fixed state of the dialysis tube.

The tube clamping assembly can be quickly and firmly fixed to the patient's skin surface by attaching it to the patient's skin surface with the adhesive film covering the bottom surface of the flexible substrate. At the same time, the tube clamping assembly can be further firmly fixed to the patient's skin surface by adhering it to the patient's skin surface with the adhesive tape on both sides of the flexible substrate. This makes it easier to fix the Y-shaped bifurcation position of the dialysis tube with the tube clamping assembly, which helps to improve the fixation effect of the dialysis tube and simplify the fixation operation.

[0017] 2. The tube clamping assembly is equipped with a fixed clamping block at the bottom and a movable clamping block at the top. At the same time, the end faces of the fixed clamping block and the movable clamping block are provided with tube limiting clamping grooves that can be aligned and closed together. Then, by the alignment and closing of the tube limiting clamping grooves at the top and bottom, the Y-shaped bifurcation position of the dialysis tube can be tightly clamped and fixed with the help of the elastic liner. This not only achieves rapid and stable fixation of the dialysis tube, but also ensures that the Y-shaped bifurcation positions of the dialysis tube are independent of each other.

[0018] 3. By using a locking ring after the connecting rod of the fixed pressure block passes through the mating hole of the movable pressure block, the movable pressure block can be quickly assembled and fixed on top of the fixed pressure block. At the same time, simply removing the locking ring allows the connecting rod to disengage from the mating hole, thus removing the movable pressure block from the top of the fixed pressure block. The assembly and disassembly of the movable pressure block on top of the fixed pressure block is simple and easy to implement. It is convenient to quickly assemble the movable pressure block on top of the fixed pressure block to fix the Y-shaped bifurcation of the dialysis tube and maintain the fixed state of the dialysis tube.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-6 As shown, this utility model provides a dialysis catheter fixing device, including a flexible substrate 2, which is placed flat. The bottom surface of the flexible substrate 2 is covered with an adhesive film 201 that can stably adhere to the skin surface. A catheter body clamping assembly 1 is assembled on the top surface of the flexible substrate 2. The flexible substrate 2 and the catheter body clamping assembly 1 are fixed to the patient's skin surface by adhering the adhesive film 201 to the skin surface. At the same time, the catheter body clamping assembly 1 is used to fix the Y-shaped bifurcation position of the dialysis catheter. Specifically, the catheter body clamping assembly 1 includes a fixed clamping block 104 and a movable clamping block 103. The fixed clamping block 104 is fixed in the middle of the top surface of the flexible substrate 2, and the movable clamping block 103 is located at the fixed clamping block 104. Above the top surface of the dialysis tube, the movable pressure block 103 and the fixed pressure block 104 are provided with tube-body limiting grooves 105 that can be aligned and closed together. The tube-body limiting grooves 105 at the upper and lower positions are aligned and closed to limit and fix the Y-shaped bifurcation position of the dialysis tube. The inner wall of the tube-body limiting grooves 105 is covered with an elastic liner 107 of buffer material. The purpose of this setting is that by aligning the tube-body limiting grooves 105 at the upper and lower positions, the elastic liner 107 can be used to tightly press and fix the Y-shaped bifurcation position of the dialysis tube. This achieves both rapid and stable fixation of the dialysis tube and ensures that the Y-shaped bifurcation positions of the dialysis tube are independent of each other.

[0030] See Figures 1-3As shown, the flexible substrate 2 and the tube clamping assembly 1 were optimized as follows. Specifically, for the flexible substrate 2, multiple adhesive tapes 3 are extended outwards from both sides of the flexible substrate 2. This arrangement facilitates the adhesion of the adhesive tapes 3 on both sides of the flexible substrate 2 to the patient's skin surface, thereby further securing the tube clamping assembly 1 firmly to the patient's skin surface. Specifically, for the tube clamping assembly 1, the elastic liner 107 is a groove whose inner contour direction is consistent with the outer contour direction of the Y-shaped bifurcation position of the dialysis tube body to be fixed. Furthermore, the front and rear ends of the elastic liner 107 are open. This arrangement facilitates the use of the elastic liner 107 to firmly and securely clamp the Y-shaped bifurcation position of the dialysis tube body.

[0031] Optionally, each of the four corners of the movable pressure block 103 has a vertically oriented mating hole 106, and all mating holes 106 are through holes. Each of the four corners of the top surface of the fixed pressure block 104 has a vertically fixed connecting rod 102. The connecting rod 102 corresponds one-to-one with the mating hole 106 and passes through the corresponding mating hole 106 in a vertical sliding engagement manner. The portion of the connecting rod 102 extending beyond the top of the mating hole 106 is coaxially and detachably fitted with a locking ring 101, and the locking ring 101 is pressed against the top surface of the movable pressure block 103. The reason for this design is that by having the connecting rod 102 of the fixed pressure block 104 pass through the mating hole 106 of the movable pressure block 103 and then adding a locking ring 101, the movable pressure block 103 can be quickly assembled and fixed on the top of the fixed pressure block 104. Simultaneously, simply removing the locking ring 101 allows the connecting rod 102 to disengage from the mating hole 106, thus detaching the movable pressure block 103 from the top of the fixed pressure block 104. The assembly and disassembly of the movable pressure block 103 on the top of the fixed pressure block 104 is simple and easy to implement. More specifically, the connecting rods 102 are all studs, and the locking rings 101 are all nuts. The locking rings 101 and connecting rods 102 are coaxially and detachably connected by threaded engagement. This design facilitates the rapid assembly and disassembly of the locking rings 101 and connecting rods 102 by turning the locking rings 101. Alternatively, all connecting rods 102 are smooth round rods, and all locking rings 101 are rubber rings. The locking rings 101 and connecting rods 102 are coaxially and detachably connected via a tension fit. This design facilitates quick assembly and disassembly of the locking rings 101 and connecting rods 102 by applying axial force through pressing and pulling. Furthermore, the outer periphery of each locking ring 101 is provided with interlocking anti-slip textures to allow for direct hand-held operation during assembly and disassembly.

[0032] Using the above structure, specifically in the process of fixing the dialysis tube, since a tube clamping assembly 1 is assembled on the top surface of the flexible substrate 2, the tube clamping assembly 1 can be quickly and firmly fixed to the patient's skin surface by adhering it to the adhesive film 201 covering the bottom surface of the flexible substrate 2. At the same time, the tube clamping assembly 1 can be further firmly fixed to the patient's skin surface by adhering it to the patient's skin surface by the adhesive tape 3 on both sides of the flexible substrate 2. Thus, it is convenient to use the tube clamping assembly 1 for dialysis. Fixing the Y-shaped bifurcation of the dialysis tubing improves the fixation effect and simplifies the fixation operation. Specifically, the tubing clamping assembly 1 has a lower fixed clamping block 104 and an upper movable clamping block 103. Both the fixed and movable clamping blocks 104 and 103 have tubing-limiting grooves 105 on their opposite end faces, allowing them to be aligned and closed together. The dialysis tubing is then clamped together by the alignment of the upper and lower clamping grooves 105, which, with the help of the elastic liner 107, secures the tubing. The Y-shaped bifurcation of the dialysis tubing is tightly clamped and fixed, achieving both rapid and stable fixation of the tubing and ensuring that the Y-shaped bifurcation points of the tubing are independent of each other. Specifically, during the assembly and disassembly of the movable pressure block 103 and the fixed pressure block 104, the movable pressure block 103 can be quickly assembled and fixed to the top of the fixed pressure block 104 by passing the connecting rod 102 of the fixed pressure block 104 through the mating hole 106 of the movable pressure block 103 and then installing a locking ring 101. This allows the movable pressure block 103 to be quickly assembled and fixed to the top of the fixed pressure block 104. Furthermore, simply removing the locking ring 101 allows the connection to be made secure. The rod 102 disengages from the mating hole 106, thereby removing the movable pressure block 103 from the top of the fixed pressure block 104. The assembly and disassembly of the movable pressure block 103 on the top of the fixed pressure block 104 is simple and easy to implement. It is convenient to quickly assemble the movable pressure block 103 on the top of the fixed pressure block 104 to fix the Y-shaped bifurcation position of the dialysis tube and maintain the fixed state of the dialysis tube. At the same time, it is convenient to remove the movable pressure block 103 from the top of the fixed pressure block 104 to remove the Y-shaped bifurcation position of the dialysis tube and release the fixed state of the dialysis tube.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
