Technical Field

[0001] The utility model belongs to the technical field of dialysis catheter fixation, and specifically relates to an auxiliary fixation device for a hemodialysis catheter. Background Technique

[0002] Hemodialysis is a renal replacement therapy method used to treat patients with acute and chronic renal failure. By guiding the patient's blood to a dialyzer, the blood and dialysate are subjected to mass exchange in a semipermeable membrane to purify the blood.

[0003] During the existing hemodialysis, a dialyzer is needed. The power pump is connected to the catheter, and then the catheter is connected to the patient. After the blood enters the dialyzer through the catheter and is purified, it flows back into the patient's body through the catheter. During long-term use and observation, it is found that the existing dialysis catheter has a relatively large number and long length. When in use, the catheter is usually directly placed on the hospital bed or instrument, resulting in the catheter being entangled and bent, which affects blood flow.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Such as Figures 1 to 5As shown in the figure, an auxiliary fixing device for a hemodialysis catheter according to an embodiment of the present utility model includes a fixing frame 1; a fixing rod 11 is fixedly connected to the top of the fixing frame 1; an adjusting component is provided at the top of the fixing rod 11; a fixing plate 12 is fixedly connected to the adjusting component; multiple storage plates 13 are fixedly connected to the top of the fixing plate 12; a plurality of storage grooves 14 are formed in the middle of the storage plate 13; the storage grooves 14 are of different sizes; a locking bolt 15 is threadedly connected to the bottom of the fixing frame 1; a gasket 16 is fixedly connected to the end of the locking bolt 15; during operation, the fixing frame 1 is clamped on the edge of a hospital bed or a table, and then the locking bolt 15 is rotated so that the gasket 16 at its end contacts the hospital bed or the table edge. At this time, the fixing frame 1 can be fixed on the hospital bed or the table edge. Then, catheters with different diameters are respectively placed in the storage grooves 14 of different sizes. At this time, the cooperation between the storage plate 13 and the storage groove 14 can classify and limit the fixation of catheters with different diameters. When the dialysis is over, the catheter is removed from the storage groove 14, and then the locking bolt 15 is rotated in the reverse direction to release the fixation of the fixing frame 1. At this time, the fixing frame 1 can be removed from the hospital bed or the table edge. Through the above structure, multiple storage plates 13 and storage grooves 14 of different sizes are provided, which can classify and limit the fixation of dialysis catheters to adapt to catheters with different diameters, and at the same time, it can reduce the situation that a large number of catheters are entangled or bent with each other, resulting in affecting the internal liquid flow.

[0026] As Figure 2 shown, the adjusting component includes a turntable 2; the turntable 2 is fixedly connected to the bottom of the fixing plate 12; a plurality of positioning holes 21 are formed in the middle of the turntable 2; a fixing ring 22 is fixedly connected to the side wall of the fixing rod 11; a spring rod 23 is slidably connected in the fixing ring 22; the spring rod 23 is arranged corresponding to the positioning holes 21; during operation, when the fixing frame 1 is fixed on the hospital bed or the table edge, the positions of the hospital bed and the table relative to the angle between the catheter and the patient will also be different. At this time, the spring rod 23 can be pulled so that its end moves out of the positioning hole 21, and then the turntable 2 can be rotated to drive the fixing plate 12 at the top to rotate. At this time, the angle of the fixing plate 12 can be changed. When it is rotated to the appropriate angle, the spring rod 23 is aligned with the positioning hole 21, and then the spring rod 23 is released to make it rebound and insert into the positioning hole 21 again. At this time, the positions of the turntable 2 and the fixing plate 12 can be fixed. Through the above structure, the turntable 2 and the positioning holes 21 are provided, and the spring rod 23 is used in cooperation, which can facilitate the angle adjustment of the fixing plate 12 to adapt to different angle usage scenarios, reduce the situation that the angle between the catheter and the storage plate 13 is too large resulting in bending, and improve the applicability and stability during use.

[0027] As Figure 1 with Figure 4As shown in the figure, a plurality of limiting frames 3 are hinged to the top of the fixing plate 12; a first magic tape 31 is fixedly connected to the end of the limiting frame 3 and the top of the fixing plate 12; the limiting frame 3 is arranged corresponding to the placing plate 13; during work, when the catheter is placed between the placing grooves 14 and limited and fixed, at this time, the limiting frame 3 can be rotated so that the first magic tape 31 at the end of the limiting frame 3 is bonded to the first magic tape 31 on the top of the fixing plate 12. At this time, the limiting frame 3 will cover the catheter placed within the placing plate 13. At this time, the catheter can be limited from above. Through the above structure, by setting the limiting frame 3 and the first magic tape 31, the catheter can be limited from above to reduce the guide. At the same time, multiple groups of limiting frames 3 can respectively cover multiple groups of placing plates 13 to reduce the situation that the catheters between multiple groups of placing plates 13 are separated during movement and cause mutual contact.

[0028] As Figure 4 shown, a fixing band 4 is fixedly connected to the side wall of the placing plate 13; a second magic tape 41 is fixedly connected to the side wall of the fixing band 4 and the side wall of the placing plate 13; during work, after the catheter is placed in the placing groove 14, the fixing band 4 is pulled to cover the top of the placing plate 13, and then the second magic tape 41 is bonded together. At this time, the fixing band 4 can fix the catheter in the placing groove 14 from the top of the placing plate 13. After use, separating the second magic tape 41 can release the fixation of the catheter. Through the above structure, by setting the fixing band 4 and the second magic tape 41, the fixing band 4 can cover the top of the placing plate 13, and the position of the catheter in the placing groove 14 can be restricted to reduce the situation that the catheter slips out of the placing groove 14.

[0029] As Figure 5 shown, two pairs of fixing ears 5 are fixedly connected to the side wall of the fixing frame 1; the two pairs of fixing ears 5 are symmetrically arranged; a fixing pin 51 is slidably fitted in the fixing ears 5; during work, when the fixing frame 1 is clamped on the side frame of the hospital bed, the fixing pin 51 is passed through the fixing ears 5. At this time, the fixing pin 51 can be clamped on the side wall of the hospital bed frame, and the position of the fixing frame 1 can be made more stable. When the use is over, first pull out the fixing pin 51, and then remove the fixing frame 1. Through the above structure, by setting the fixing ears 5 and the fixing pin 51, the stability of the position where the fixing frame 1 is clamped on the hospital bed frame can be improved to reduce the situation that the fixing frame 1 falls off.

[0030] As Figure 4 shown, an elastic cloth 6 is fixedly connected to the side walls of a group of placing plates 13; the top of the elastic cloth 6 and the bottom of the placing groove 14 are horizontally arranged; during work, when a group of catheters are placed in the placing groove 14, the catheters between a group of placing plates 13 will contact the elastic cloth 6. At this time, the elastic cloth 6 will support the catheters from below. Through the above structure, by setting the elastic cloth 6 to connect the placing plates 13, the situation that the catheters sag between the placing plates 13 and cause the catheters to bend can be reduced, so as to improve the stability of the position of the catheters during use.

[0031] As Figure 5 shown, a rubber pad 7 is fixedly connected to the top of the gasket 16; during operation, when the gasket 16 contacts the hospital bed frame or the tabletop, the rubber pad 7 located at the top of the gasket 16 will contact the hospital bed frame or the table edge. Through the above structure, the rubber pad 7 is provided to connect the gasket 16, which can increase the friction between the gasket 16 and the hospital bed frame or the table edge, so as to improve the fixing effect of the fixing frame 1, and at the same time reduce the wear caused by the extrusion of the gasket 16 on the hospital bed frame or the table edge.

[0032] Working principle: Clamp the fixing frame 1 on the hospital bed or the table edge, and then rotate the locking bolt 15 so that the gasket 16 at its end contacts the hospital bed or the table edge. At this time, the fixing frame 1 can be fixed on the hospital bed or the table edge. Then, place catheters with different diameters in the different-sized storage grooves 14 respectively. At this time, the storage plate 13 and the storage grooves 14 cooperate to classify and limit the fixation of catheters with different diameters. After dialysis, remove the catheter from the storage groove 14, and then rotate the locking bolt 15 in the reverse direction to release the fixation of the fixing frame 1. At this time, the fixing frame 1 can be removed from the hospital bed or the table edge. When the fixing frame 1 is fixed on the hospital bed or the table edge, the positions of the hospital bed and the table relative to the angle between the catheter and the patient will also be different. At this time, pull the spring rod 23 so that its end moves out of the positioning hole 21, and then rotate the turntable 2 to drive the top fixing plate 12 to rotate. At this time, the angle of the fixing plate 12 can be changed. When it is rotated to the appropriate angle, align the spring rod 23 with the positioning hole 21, and then release the spring rod 23 to make it rebound and insert into the positioning hole 21 again. At this time, the positions of the turntable 2 and the fixing plate 12 can be fixed. After the catheter is placed and limited between the storage grooves 14, rotate the limiting frame 3 so that the first magic tape 31 at the end of the limiting frame 3 adheres to the first magic tape 31 on the top of the fixing plate 12. At this time, the limiting frame 3 will cover the catheter placed within the storage plate 13, and at this time, it can limit the catheter from above. After the catheter is placed in the storage groove 14, pull the fixing belt 4 to cover the top of the storage plate 13, and then bond the second magic tape 41 together. At this time, the fixing belt 4 can fix the catheter in the storage groove 14 from the top of the storage plate 13. After use, separate the second magic tape 41 to release the fixation of the catheter. When clamping the fixing frame 1 on the border of the hospital bed, pass the fixing pin 51 through the fixing ear 5. At this time, the fixing pin 51 can be stuck on the side wall of the hospital bed border, which can make the position of the fixing frame 1 more stable. After use, first pull out the fixing pin 51, and then remove the fixing frame 1. When a group of catheters are placed in the storage grooves 14, the catheters between a group of storage plates 13 will contact the elastic cloth 6. At this time, the elastic cloth 6 will support the catheter from below. When the gasket 16 contacts the hospital bed border or the tabletop, the rubber pad 7 located at the top of the gasket 16 will contact the hospital bed border or the table edge.
