Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a dialysis fixing device. Background Art
[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The electrolyte solution (dialysate) with similar concentrations between the blood and the body exchanges substances through diffusion and convection inside and outside the hollow fibers, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The entire process is called hemodialysis. During dialysis, a fixing device is required to fix the pipeline.
[0003] Some existing pipeline fixing devices are often difficult to adjust flexibly when the pipeline angle needs to be adjusted. This usually happens when the patient's body position changes or the direction of the dialysis pipeline needs to be changed during treatment. Due to the lack of a convenient adjustment mechanism, medical staff have to frequently disassemble and reinstall the fixing device, which not only increases the complexity of the operation, but may also cause increased discomfort to the patient. Secondly, the design of existing fixing devices mostly wraps the patient's abdomen or arms and other parts with Velcro. When the patient moves his arms or swings his body, the Velcro straps will move with the shaking of the patient's body or arms, causing the fixing device to deviate, pulling the dialysis tube and affecting blood transfusion. Therefore, in response to the above problems, a dialysis fixing device is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1 to 3 The present invention provides an embodiment of a dialysis fixture, comprising a positioning plate 1 and an information card 26. A spring plate 2 is fixedly connected to the bottom end of the positioning plate 1, which helps maintain close contact between the positioning plate 1 and the bed surface. Slots 3 are formed on both sides of the positioning plate 1. Fixing straps 4 are slidably connected to the inner walls of the two slots 3. The outer portions of the fixing straps 4 slide within the slots 3. The outer portions of the slots 3 are smooth, facilitating sliding.
[0033] The outer portion of the fixing strap 4 slides over the top of the spring plate 2, ensuring that the fixing strap 4 can slide against the positioning plate 1. A limit ring 5 is fixedly attached to the top left of the fixing strap 4, which limits the position of the fixing strap 4. A hook 6 is provided on the right side of the fixing strap 4, and a velvet surface 7 is provided on the top right side of the fixing strap 4. The bottom end of the velvet surface 7 is adhered to the outer portion of the hook 6, and the two parts are attached to each other using Velcro.
[0034] refer to Figure 2 、 Figure 3The top left side of the fixing belt 4 is fixedly connected to a support plate 8, which is used to position and support the dialysis tube. The top of the support plate 8 is fixedly connected to four spherical shell rods 9, and the top of the spherical shell rod 9 is internally rotatably connected to a spherical rod 10. The spherical shell rod 9 and the spherical rod 10 components allow the dialysis tube to rotate in multiple axial directions. The top of the spherical rod 10 is fixedly connected to an arc block 11. The arc block 11 is an arc-shaped structure used to accommodate the dialysis tube. The top left and right sides of the arc block 11 are fixedly connected to two limit blocks 12, and the middle parts of the two limit blocks 12 are fixedly connected to a positioning roller 13. The limit blocks 12 and the positioning roller 13 components ensure that the dialysis tube is fixed in the appropriate position. The outer surface of the positioning roller 13 is provided with a torsion spring 14, and the front and rear sides of the outer surface of the positioning roller 13 are fixedly connected to a rotating block 15. The torsion spring 14 provides the necessary elastic force to maintain the position of the dialysis tube.
[0035] The top ends of the two rotating blocks 15 are fixedly connected to a fixing assembly, which includes a rotating plate 16. The outer top ends of the two rotating blocks 15 are fixedly connected to the front and rear sides of the bottom end of the rotating plate 16. The rotating plate 16 is used to fix the rubber block 17. One end of the torsion spring 14 is fixedly connected to the left and right top ends of the arc block 11, and the outer end of the torsion spring 14 is in contact with the side of the rotating plate 16 away from the rubber block 17. Because one end of the torsion spring 14 is fixed to the inner top end of the limit block 12 and the other end is in contact with the outer side of the rotating plate 16, the torsion spring 14 will elastically drive the rotating plate 16 and the rubber block 17 to return to their original position, flexibly clamping and fixing the outside of the pipeline.
[0036] A rubber block 17 is fixedly connected to one side of the rotating plate 16 near the arc block 11. The rubber block 17 is used to increase friction and prevent the dialysis tube from slipping out. The adjacent sides of the two rotating blocks 15 are rotatably connected to the adjacent sides of the two limit blocks 12 to ensure that the rotating plate 16 rotates stably.
[0037] refer to Figure 4 、 Figure 5 The bottom end of the fixing strap 4 is provided with a plurality of locking holes 18, and the middle portion of the bottom end of the positioning plate 1 is provided with a groove 19. A clip 20 is slidably connected to the inside of the groove 19, and the outside of the clip 20 engages with the inner wall of the locking hole 18. The clip 18, these holes are used to cooperate with the clip 20 to adjust the length of the fixing strap 4. A positioning groove 21 is provided in the middle of the clip 20, and a telescopic rod 22 is fixedly connected to the inner bottom end of the positioning groove 21. The positioning groove 21 and the telescopic rod 22 allow the clip 20 to extend and retract within a certain range. A flexible spring 23 is sleeved on the outside of the telescopic rod 22. One end of the flexible spring 23 is fixedly connected to the inner top end of the groove 19, and the other end of the flexible spring 23 is fixedly connected to the inner wall of the positioning groove 21. The flexible spring 23 provides the necessary elastic force to maintain the position of the clip 20.
[0038] The right side of the positioning plate 1 is fixedly connected to a ring 24, and the outer portion of the ring 24 is slidably connected to a transparent card box 25. The outer portion of the information card 26 is engaged with the inner portion of the transparent card box 25. By placing the written information on the information card 26 in the transparent card box 25, medical staff can quickly identify patient information.
[0039] Working principle: When in use, first place the positioning plate 1 on the bed surface as needed, then place the patient's arm on the top of the positioning plate 1, and then pass the right end of the fixing belt 4 through the limiting ring 5 according to the size of the patient's wrist or arm, and then fit the velvet surface 7 on the right side of the fixing belt 4 to the hook surface 6, so that the device can be fixed on the patient's arm for use. At this time, press the positioning plate 1 again to engage the clamp 20 at the top of the positioning plate 1 into the clamping hole 18 of the fixing belt 4, and then pull the fixing belt 4 to slide into the through groove 3 according to the position of the support plate 8, so that the fixing belt 4 will be squeezed after being pulled, and the clamp 20 at the bottom of the fixing belt 4 will expand and contract under the pulling and squeezing of the fixing belt 4, and engage with the clamping holes 18 in different positions, so as to maintain the center position of the support plate 8, and cooperate with the positioning plate 1 and the spring sheet 2 to fit the bed surface, so as to ensure that the fixing device will not shift during use.
[0040] After the positions of the fixing belt 4 and the support plate 8 are adjusted, one side of the rubber block 17 can be bent to allow the rubber block 17 to squeeze the rotating block 15 and rotate, thereby placing the dialysis tube on the top of the arc block 11. Afterwards, since one end of the torsion spring 14 is fixed to the top inner part of the limit block 12 and the other end is attached to the outside of the rotating plate 16, the torsion spring 14 will elastically drive the rotating plate 16 and the rubber block 17 to reset and flexibly clamp the outside of the tube, combing the tube and facilitating the medical work of hemodialysis. The spherical rod 10 fixed at the bottom end of the arc block 11 can be movably rotated within the spherical shell rod 9 to rotate at multiple angles, thereby achieving multi-angle fixation of the tube, ensuring that the dialysis tube is always kept in the optimal position and reducing the pulling or twisting of the tube caused by changes in body position.
[0041] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
