Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a pipeline fixer for hemodialysis. Background Art
[0002] Hemodialysis is a common method for treating acute and chronic renal failure. At present, there is a lack of dedicated hemodialysis pipeline fixing devices in actual hemodialysis work. Most dialysis centers generally use hemostatic forceps to fix the blood line tubes on quilts, clothes, and sheets. This fixing method often has disadvantages such as ineffective fixation, accidental clamping or clamping of the pipeline. In addition, patients usually undergo dialysis many times a week and for a long time. During the dialysis process, the blood line is filled with blood and has a certain weight. When the patient performs activities such as turning over and eating, the risk of pipeline folding, pulling and slipping is greatly increased. Once the pipeline slips, the patient will bleed profusely, which can threaten the patient's life in severe cases. Therefore, the present application proposes a hemodialysis pipeline fixer to solve the above problems. Utility Model Content
[0003] The utility model provides a hemodialysis pipe fixer to solve the problems raised in the above background technology.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0005] A hemodialysis pipeline fixer comprises a box body, wherein the box body is provided with a groove, a connecting component is installed on the outer side of the box body, and a limited position abutment mechanism is installed on the inner wall of one side of the groove.
[0006] A further improvement of the technical solution of the utility model is that the limiting abutment mechanism includes a movable groove opened on the box body, and the movable groove is connected to the inner side of the groove, a rotating shaft is installed on the inner wall of the movable groove, a movable abutment block is installed on the outer surface of the rotating shaft, one side of the movable abutment block extends to the inner side of the groove, and an elastic reset component is installed on the side of the movable abutment block close to the movable groove.
[0007] A further improvement of the technical solution of the utility model is that the elastic reset component includes a fixed shaft installed on the back of the movable abutment block, a movable connecting rod is movably connected to the outer surface of the fixed shaft, one end of the movable connecting rod extends to the outside of the box body and is movably connected to the inner wall of the box body, a connecting ring is connected to the outer surface of the movable connecting rod, and a spring is sleeved on the inner outer surface of the movable groove, and the two ends of the spring are respectively connected to the outer surface of the connecting ring and the inner wall of the movable groove.
[0008] A further improvement of the technical solution of the utility model is that: one end of the movable connecting rod extending to the outside of the box body is connected to a limited connecting plate, and a pulling groove is provided on the limited connecting plate.

[0019] The present invention is further described in detail below in conjunction with the embodiments:
[0020] Example 1
[0021] like Figure 1-4 As shown, the utility model provides a hemodialysis pipeline fixer, including a box body 1, the box body 1 is provided with a groove 2, a connecting component is installed on the outer side of the box body 1, a limited abutment mechanism is installed on the inner wall of one side of the groove 2, the box body 1 is made of plastic or soft material, the inner diameter of the groove 2 is the same as that of the hemodialysis pipeline, when the patient undergoes hemodialysis, the hemodialysis pipeline can be clamped into the groove 2 with the help of the limited abutment mechanism, and then the device is fixed on the bed sheet through the action of the connecting component, so as to avoid the pipeline folding, pulling and slipping due to the patient's activities such as turning over and eating.
[0022] Furthermore, the limiting abutment mechanism includes a movable groove 5 provided on the box body 1, and the movable groove 5 is connected with the inner side of the groove 2, a rotating shaft 7 is installed on the inner wall of the movable groove 5, and a movable abutment block 6 is installed on the outer surface of the rotating shaft 7, one side of the movable abutment block 6 extends to the inner side of the groove 2, and an elastic reset component is installed on the side of the movable abutment block 6 close to the movable groove 5. When the dialysis tubing is pressed toward the inner side of the groove 2, an extrusion effect is generated on the movable abutment block 6, so that the movable abutment block 6 rotates a certain angle toward the inner side of the movable groove 5 along the rotating shaft 7. When the dialysis tubing slides into the groove 2, the top of the dialysis tubing is separated from the movable abutment block 6, and the movable abutment block 6 rebounds to its original position under the action of the elastic reset component and abuts with the outer side of the dialysis tubing, thereby ensuring the connection stability between the box body 1 and the dialysis tubing.
[0023] Furthermore, the elastic reset component includes a fixed shaft 8 installed on the back side of the movable abutment block 6, and a movable connecting rod 9 is movably connected to the outer surface of the fixed shaft 8. One end of the movable connecting rod 9 extends to the outside of the box body 1 and is movably connected to the inner wall of the box body 1. A connecting ring 10 is connected to the outer surface of the movable connecting rod 9. The movable connecting rod 9 is located on the inner outer surface of the movable groove 5 and is sleeved with a spring 11. The two ends of the spring 11 are respectively connected to the outer surface of the connecting ring 10 and the inner wall of the movable groove 5. When the movable abutment block 6 rotates toward the inside of the movable groove 5, the fixed shaft 8 pushes the movable connecting rod 9 to slide outward along the box body 1, and compresses the spring 11 to cause it to undergo elastic deformation. When the dialysis pipeline is installed and clamped, the movable abutment block 6 rebounds to its original position under the action of the compression spring 11 and abuts against the outer side of the dialysis pipeline.
[0024] Furthermore, one end of the movable connecting rod 9 extending to the outside of the box body 1 is connected to a limited connecting plate 12, and a pulling groove 13 is provided on the limited connecting plate 12. When the dialysis pipeline needs to be separated from the box body 1, the limited connecting plate 12 only needs to be pushed outward to drive the movable abutment block 6 to rotate to the inside of the movable groove 5 through the movable connecting rod 9. At this time, the dialysis pipeline can be separated from the groove 2.
[0025] Furthermore, the connecting component includes a fixing clip 3, which is installed on the side of the box body 1. The fixing clip 3 is a clip structure in the prior art, which can fix the box body 1 on the bed sheet. The fixing clip 3 can be removed, and a pin is installed at the bottom of the box body 1 to connect the box body 1 to the bed sheet, or other methods that can be fixedly connected to the bed sheet can be adopted, and it can also be fixed on the clothes of the patient's puncture side limb as needed.
[0026] Furthermore, a plurality of snap-fit hemispheres 4 are mounted on the inner wall of the groove 2 opposite to the movable abutment block 6 to assist in fixing the dialysis pipeline.
[0027] The working principle of the hemodialysis tubing fixer is described in detail below.
[0028] like Figure 1-4 As shown, when the patient undergoes hemodialysis, when the dialysis tubing is pressed toward the inside of the groove 2, an extrusion effect is generated on the movable abutment block 6, causing the movable abutment block 6 to rotate a certain angle toward the inside of the movable groove 5 along the rotating shaft 7, and a pushing effect is generated on the movable connecting rod 9 through the fixed shaft 8 to slide outward along the box body 1, and the spring 11 is compressed to cause it to undergo elastic deformation. When the dialysis tubing slides into the groove 2, the top of the dialysis tubing is separated from the movable abutment block 6, and the movable abutment block 6 rebounds to its original position under the action of the compression spring 11, and abuts against the outside of the dialysis tubing, thereby ensuring the connection stability between the box body 1 and the dialysis tubing.
