Description

Technical Field

[0001] The invention relates to the technical field of dialysis tubing fixing devices, and in particular to a portable dialysis tubing fixing device. Background Art

[0002] The hemodialysis machine uses the principles of dialysis and hydrostatic pressure. It consists of a part through which the patient's blood passes, a part through which the dialysate passes, and a semi-permeable membrane in between. Through the micropores of the membrane, waste and excess water flow from the blood into the dialysate, while components such as blood cells and proteins needed by our body are relatively large and cannot pass through the holes and remain as they are. Specifically, it includes a monitoring system, a pumping system, a dialysis filtration system, etc. on the dialysis machine side, as well as an external disposable dialysis line. The disposable dialysis line includes an arterial line marked in red and a venous line marked in blue. When in use, the machine-side ports of the arterial line and the venous line are respectively connected to the two ends of the dialysis filter, and the machine-side monitoring ports and arterial pots of the arterial line and the venous line are fixed to the dialysis machine. The other end ports of the arterial line and the venous line are connected to the patient's indwelling tube. However, the dialysis line is long and is a hose, which is not easy to place and store.

Although it effectively stores redundant tubing and clamps the tubing firmly, if the dialysis machine, the patient himself or other external factors accidentally pull the tubing, there is still a great risk of derailment or secondary injury to the patient, so it is not enough to meet the demand for further convenient and safe fixation and anti-pulling of dialysis tubing. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a portable dialysis tubing fixer to solve the problem that the existing conventional hemodialysis tubing fixer is not sufficient to meet the needs of further convenient and safe fixation and anti-pulling use of the dialysis tubing.

[0004] Based on the above purpose, the present invention provides a portable dialysis tubing fixer for fixing the arterial tubing and venous tubing of dialysis, comprising:

[0005] A fixed shaft, a plurality of collar members are slidably arranged along the fixed shaft, and adjacent collar members are respectively connected with a first vertical plate and a second vertical plate, the first vertical plate is fixedly connected to the collar member, and the second vertical plate is rotatably connected to the collar member, and elastic members are connected between the collar members for pulling each collar member to slide closer;

[0006] The clamping plate is arranged at both ends of each first vertical plate and the second vertical plate, a through groove is opened in the clamping plate in a direction parallel to the axial direction of the fixed axis, and a through opening is opened at one end of the through groove away from the fixed axis, and the arterial pipeline and the venous pipeline are respectively passed through the through grooves at both ends, and are rotated 180 degrees through the second vertical plate so that the arterial pipeline and the venous pipeline are wound along each through groove in an S shape;

[0007] The push blocks are arranged on both sides of the through opening and are elastically connected to the through opening. When the arterial pipeline and the venous pipeline are pressed inward along the through opening, the push blocks are pushed to slide open until the arterial pipeline and the venous pipeline are completely inserted into the through groove.

Push blocks 7 are provided on both sides of the opening 62 and are elastically connected to the opening 62. When the arterial pipeline 100 and the venous pipeline 200 are pressed inwardly along the opening 62, the push blocks 7 are pushed to slide open until the arterial pipeline 100 and the venous pipeline 200 are completely inserted into the through groove 61, and the push blocks 7 on both sides slide close to each other. A slide groove 63 is provided in the through groove 61 on the first vertical plate 3 below the opening 62. A clamping block 8 is slidably connected in the slide groove 63. One end of the clamping block 8 is connected to the push block 7. Strip slide seats 10 are provided at the upper and lower ends of the inner side of the fixed shell 9. The strip slide seat 10 is arranged parallel to the axial direction of the fixed shaft 1. A guide sliding member 11 is provided in the strip slide seat 10. When the fixed shell 9 is clamped on the outer sides of the fixed shaft 1, the first vertical plate 3 and the second vertical plate 4, the guide sliding member 11 pushes the push block 7 to make the clamping blocks 8 on both sides slide inward and abut against and fix the arterial pipeline 100 and the venous pipeline 200.

[0036] The present invention is based on the existing hemodialysis machine and the external disposable dialysis pipeline structure. Considering that the existing disposable dialysis pipeline includes an arterial pipeline 100 marked in red and a venous pipeline 200 marked in blue, when in use, the machine-end ports of the arterial pipeline 100 and the venous pipeline 200 are generally connected to the two ends of the dialysis filter at the machine end, and the machine-end monitoring ports, arterial pots, etc. of the arterial pipeline 100 and the venous pipeline 200 are fixed to the dialysis machine. The other end ports of the arterial pipeline 100 and the venous pipeline 200 are connected to the patient's indwelling tube. However, the dialysis pipeline is long and is a soft tube, which is not easy to place and store. If it is accidentally pulled, it is easy to get off the line or cause secondary damage to the patient. In this regard, a fixed shaft 1 is provided, and a plurality of collar members 2 are slidably provided along the fixed shaft 1, and adjacent collar members 2 are respectively connected with a first vertical plate 3 and a second vertical plate 4, the first vertical plate 3 is fixedly connected to the collar member 2, and the second vertical plate 4 is rotatably connected to the collar member 2, and an elastic member 5 is connected between the collar members 2 for pulling each collar member 2 to slide closer, and a clamping plate 6 is provided at both ends of each first vertical plate 3 and the second vertical plate 4, and a through groove 61 is provided in the clamping plate 6 in a direction parallel to the axial direction of the fixed shaft 1, and a through opening 62 is provided at one end of the through groove 61 away from the fixed shaft 1, and the arterial pipeline 100 and the venous pipeline 200 are respectively penetrated in the through groove 61 at both ends, and the second vertical plate 4 is rotated 1 80°, so that the arterial pipeline 100 and the venous pipeline 200 are arranged in an S shape along each through groove 61, and push blocks 7 are provided on both sides of the through opening 62 and are elastically connected to the through opening 62. When the arterial pipeline 100 and the venous pipeline 200 are pressed inward along the through opening 62, the push blocks 7 are pushed to slide open until the arterial pipeline 100 and the venous pipeline 200 are completely inserted into the through groove 61, and the push blocks 7 on both sides slide close to reset, thereby partially closing the through opening 62, playing a certain role in limiting the pipeline and preventing the pipeline from slipping out of the through opening 62. A slide groove 63 is provided below the through opening 62 in the through groove 61 on the first vertical plate 3, and a clamping block 8 is slidably connected in the slide groove 63. One end of the clamping block 8 Connected to the push block 7, the upper and lower ends of the inner side of the fixed shell 9 are provided with a strip slide 10, the strip slide 10 is arranged parallel to the axial direction of the fixed shaft 1, and a guide sliding member 11 is arranged in the strip slide 10. When the fixed shell 9 is clamped on the fixed shaft 1, the first vertical plate 3 and the second vertical plate 4, the guide sliding member 11 pushes the push block 7 to make the clamping blocks 8 on both sides slide inward and abut against the fixed arterial pipeline 100 and the venous pipeline 200, wherein the second vertical plate 4 is designed with an elastic telescopic structure, similar to the existing conventional elastic telescopic rod structure. When in use, the arterial pipeline 100 and the venous pipeline 200 only need to be pressed inward into the through groove 61 along the through openings 62 at the upper and lower ends, as shown in FIG. Figure 1 As shown, the arterial line 100 and the venous line 200 are provided with the through grooves 61 in the axial direction parallel to the fixed axis 1. The second vertical plate 4 only needs to be rotated 180°. Figure 2As shown, the arterial line 100 and the venous line 200 are arranged in an S-shaped manner along the through grooves 61 one after the other, so as to realize the convenient storage of the redundant dialysis lines. Figure 3 , Figure 4 , Figure 5 As shown, the fixed shell 9 is clamped on the fixed shaft 1, the first vertical plate 3 and the second vertical plate 4. The guide sliding member 11, on the one hand, pushes the push block 7 to make the clamping blocks 8 on both sides slide inward and abut against the arterial line 100 and the venous line 200, that is, the arterial line 100 and the venous line 200 on the first vertical plate 3 are clamped and fixed, and on the other hand, the clamping plate 6 is affixed to the guide sliding member 11 for efficient sliding. When the dialysis line is accidentally pulled, the first vertical plate 3 and the second vertical plate 4 are driven to slide laterally. The second vertical plate 4 is elastically contracted along its length direction, and the elastic member 5 is stretched and elongated to play the role of elastic buffer, that is, the S-shaped pipeline is tended to be straightened to avoid the risk of derailment or secondary injury to the patient, and when the pulling force is reduced, the first vertical plate 3, the second vertical plate 4 and the ring members 2 are reset under the pulling force of the elastic member 5, and the dialysis pipeline recovers to its original S shape, thereby realizing further convenient and safe fixation and anti-pulling use of the dialysis pipeline.

[0037] In an embodiment of the present invention, Figures 1 to 11 As shown, the top end surface of the push block 7 that penetrates into the through hole 62 is designed to be an inclined end surface. In the initial state, as shown in FIG. Fig.10 As shown, the push blocks 7 on both sides slide close to each other, thereby partially closing the through opening 62, playing a certain role in limiting the pipeline and preventing the pipeline from slipping out of the through opening 62. Considering that the end of the dialysis pipeline is provided with an interface, it is not convenient to directly penetrate the through groove 61. When in use, the end of the dialysis pipeline close to the patient is pressed inward along the through opening 62, and the pipeline pushes the inclined top surface of the push block 7 to slide outward and open until the dialysis pipeline is completely pressed into the through groove 61. Fig.10 As shown, the push blocks 7 on both sides slide close to reset, wherein existing conventional elastic components such as springs are connected between the push blocks 7 and the through-port 62 to achieve elastic connection and reset between the push blocks 7 and the through-port 62. Optionally, the bottom end surface of the push block 7 that penetrates into the through-port 62 is also designed to be an inclined end surface. When disassembling, the pipeline is pulled outward with force to push the bottom inclined end surface of the push block 7 to make the push block 7 slide open. The used pipeline can also be taken out by directly pulling the push block 7 outward.

[0038] In an embodiment of the present invention, Figures 1 to 11As shown, the side of the clamp block 8 facing the through groove 61 is designed with an arc-shaped end surface, which is used to abut and clamp the arterial pipeline 100 and the venous pipeline 200. Preferably, an elastic anti-skid pad layer 81 is attached to the arc-shaped end surface of the clamp block 8, and the elastic anti-skid pad layer 81 can be made of existing conventional materials such as rubber, wherein the end of the clamp block 8 away from the through groove 61 is fixedly connected to the end of the push block 7 away from the through groove 61. When the fixed shell 9 is clamped on the outside of the fixed shaft 1, the first vertical plate 3 and the second vertical plate 4, the push block 7 is pushed inwardly through the guide sliding member 11, as shown in FIG. Fig.11 As shown, the push blocks 7 on both sides slide closer to each other, closing the through opening 62, and at the same time driving the clamping block 8 to slide into the through groove 61 along the slide groove 63, and closely abut against and fix the arterial pipeline 100 and the venous pipeline 200.

[0039] In an embodiment of the present invention, Figures 1 to 11 As shown, the inner ring of the collar member 2 is provided with a plurality of first rolling steel balls 21 spaced apart along its circumference, and the outer side of the fixed shaft 1 is provided with a plurality of corresponding grooves 12 along its length direction. The first rolling steel balls 21 are correspondingly engaged in each groove 12 and slide freely along the length direction of the groove 12, thereby realizing efficient sliding of the collar member 2 along the outer side of the fixed shaft 1 and preventing axial rotation along the fixed shaft 1.

[0040] In an embodiment of the present invention, Figures 1 to 11 As shown, the groove 12 includes short grooves 121 located at both ends of the fixed shaft 1, and a long groove 122 located in the length direction of the fixed shaft 1. The short groove 121 and the long groove 122 are designed to be staggered, that is, the short groove 121 and the long groove 122 are located at parallel and staggered positions on the outer side of the fixed shaft 1, wherein the outermost collar member 2 is slidably connected to the short groove 121, and the remaining collar members 2 are slidably connected to the long groove 122, for example Figure 2 As shown, the pipeline on the left is close to the patient end, and the pipeline on the right is connected to the machine end. The leftmost and rightmost collar members 2 are slidably connected to the short groove 121, and the short groove 121 extends inwardly along the end of the fixed shaft 1 for a certain distance. The remaining collar members 2 are all slidably connected to the long groove 122, and the long groove 122 extends along the entire length direction of the fixed shaft 1. Therefore, when the patient end pulls the pipeline to the left, the rightmost collar member 2 is restricted by the short groove 121 and cannot slide to the left. Except for the rightmost collar member 2, all other collar members 2 slide to the left and unfold, playing the role of elastic buffer. If the machine end When the pipeline is pulled to the right, on the contrary, the leftmost ring member 2 is restricted by the short groove 121 and cannot slide to the left. Except for the leftmost ring member 2, all other ring members 2 slide and expand to the right, playing the role of elastic buffering. Even if the ring member 2 slides and expands to the right to the limit, it will not pull the leftmost ring member 2 to move right, which greatly reduces the risk of secondary injury to the patient end. Among them, one end of the short groove 121 and the long groove 122 can extend to the end of the fixed shaft 1, so that the ring member 2 can be easily slid and installed on the fixed shaft 1 along the extended end.

[0041] In an embodiment of the present invention, Figures 1 to 11 As shown, an annular sleeve 41 is fixed to one end of the second vertical plate 4, and an annular groove 22 is provided on the corresponding collar member 2. The annular sleeve 41 is slidably connected to the annular groove 22, that is, the annular sleeve 41 is embedded in the outer periphery of the collar member 2, so that the annular sleeve 41 can rotate freely around the axial direction of the collar member 2. More preferably, a limit pin 13 is embedded in the inside of one end of the second vertical plate 4 close to the collar member 2, and an elastic component such as a return spring is connected between the limit pin 13 and the inside of the second vertical plate 4. Pin holes are correspondingly provided on both sides of the collar member 2 and the annular sleeve 41, and one end of the limit pin 13 is connected to a push rod 14, and one end of the push rod 14 passes through the outside of the second vertical plate 4. By pulling the push rod 14, the limit pin 13 is driven to move out of the pin hole, thereby rotating the second vertical plate 4 180°, and the limit pin 13 is acted upon by the return spring and is again inserted into the pin hole and locked.

[0042] In an embodiment of the present invention, Figures 1 to 11 As shown, the guide sliding member 11 is a second rolling steel ball rollingly connected to the strip sliding seat 10, so as to facilitate the efficient sliding of the clamp 6 along the guide sliding member 11, and the second rolling steel ball stably pushes the clamp block 8 to slide inward, thereby achieving clamping and fixing of the arterial line 100 and the venous line 200.

[0043] In an embodiment of the present invention, Figures 1 to 11 As shown, the fixed shell 9 includes an upper shell 91 and a lower shell 92 which are clamped on the outside of the fixed shaft 1, the first vertical plate 3 and the second vertical plate 4. When the upper shell 91 and the lower shell 92 are clamped together, a space for the ring member 2, the first vertical plate 3 and the second vertical plate 4 to slide horizontally is reserved in the fixed shell 9. Both ends of the fixed shell 9 are provided with tube holes 93 for the arterial pipeline 100 and the venous pipeline 200 to pass through, and an axial hole 94 for the fixed shaft 1 to pass through. Specifically, the upper shell 91 and the lower shell 92 can be connected by conventional bolts, or by a more convenient conventional plastic buckle or plastic pin structure. The outside of the fixed shell 9 can be connected with a conventional Velcro strap structure to facilitate fixing the fixator to a position such as a bedside railing.

[0044] In an embodiment of the present invention, Figures 1 to 11 As shown, a shaft cap 15 is connected to the end of the fixed shaft 1, which is used to prevent the ring member 2 from slipping out on the one hand, and to limit the fixed shell 9 and the fixed shaft 1 in the left and right directions on the other hand. Specifically, the shaft cap 15 can be connected to the end of the fixed shaft 1 by means of threaded connection or the like.

[0045] In an embodiment of the present invention, Figures 1 to 11 As shown, the elastic member 5 is connected to the upper and lower ends of the adjacent collar member 2 to avoid interference with the wound pipeline. The elastic member 5 can be specifically an elastic member such as a tension spring.
