Abstract
Description
Technical Field
[0001] The invention relates to the technical field of hemodialysis tubes, in particular to a hemodialysis tube fixing and protective sleeve device for hemodialysis. 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 blood and an electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged through diffusion and convection inside and outside the hollow fibers, thereby removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The entire process of returning the purified blood is called hemodialysis.
[0003] Hemodialysis tubing is a medical supply required for hemodialysis. Medical staff usually use hemodialysis tubing to treat patients. During dialysis, a needle is inserted into the patient's blood vessel, and the catheter transfers the blood to the hemodialysis machine, and then returns the dialyzed blood to the patient's body. The catheter used in this process is generally thicker and longer, and is prone to movement, causing pain or blood vessel puncture to the patient. Therefore, a hemodialysis tubing fixing and protective sleeve device is needed to fix and protect it.
[0004] Currently, most hemodialysis tubes on the market are fixed by sticking medical tape on the skin surface of the patient's forearm. During the treatment process, the medical tape will lose its stickiness due to the patient's own sweating and fall off the patient's skin surface, causing the hemodialysis tube to lose its fixation, affecting the treatment. Moreover, when the catheter is long, multiple tapes need to be attached to fix it. After the hemodialysis is completed, some tapes are difficult to remove and take a long time to tear off, which increases the patient's pain. Summary of the Invention
[0005] The object of the present invention is to provide a device for fixing a protective cover of a hemodialysis tube for hemodialysis, so as to solve the problem in the above background technology that most of the existing hemodialysis tubes are fixed by tape, but the tape fixation is easy to fall off, which reduces the stability of the fixation, and when fixing a longer catheter, multiple tapes are required, and long-term adhesion will increase the pain of the patient when removing it. In order to achieve the above object, the present invention provides the following technical solution: A device for fixing a protective cover of a hemodialysis tube for hemodialysis, comprising an annular plate, one end of the annular plate is fixedly connected to a first strap, the other end of the annular plate is fixedly connected to a second strap, the interior of the annular plate is provided with an extension plate that can slide horizontally, the top of the annular plate and the extension plate are fixed with a mounting seat, the middle of the mounting seat is provided with an adjustable reinforcement ring, and the middle of the reinforcement ring clamps the hemodialysis tube.
[0006] Preferably, a flexible breathable pad is glued to the inner wall of the annular plate.
[0007] Preferably, the outer wall of the first strap is glued with a Velcro hook surface, the inner wall of the second strap is glued with a Velcro felt surface, and the Velcro hook surface and the Velcro felt surface are bonded.
[0008] Preferably, a fixed block is fixed inside the annular plate, the end side of the fixed block is rotatably connected to a screw, the end side of the screw is fixed with a rocker, the external thread of the screw is sleeved with a sliding rod, the end side of the sliding rod is fixed with a mounting block, and a telescopic rod is fixedly connected between the mounting block and the fixed block.
[0009] Preferably, a sliding groove is provided inside the annular plate to facilitate horizontal sliding of the extension plate.
[0010] Preferably, a support block is fixed on the inner wall of the mounting seat, and there are two support blocks. A support rod is fixedly connected between the two support blocks. A slider is slidably sleeved on the outside of the support rod, and there are two sliders. A spring is fixedly connected between the two sliders, and the spring is sleeved on the support rod.
[0011] Preferably, a connecting rod is hinged on the end side of the sliding block, a connecting block is hinged on the end side of the connecting rod, and the connecting block is fixedly connected to the reinforcement ring.
[0012] Preferably, an anti-wear pad is glued to the inner wall of the reinforcement ring.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In the present invention, the annular plate is attached to the patient's arm and adhered to it by means of a first strap and a second strap, thereby fixing the hemodialysis catheter on the patient's arm. At the same time, the strap is an elastic band, which has elastic force during the binding process, thereby improving the comfort of use and solving the problems of discomfort and easy falling off caused by fixing with adhesive tape.
[0015] In the present invention, the lengths of the hemodialysis tubes are different. When fixing the hemodialysis tubes, the fixed position of the hemodialysis tubes can be adjusted according to their lengths, so that the length of the hemodialysis tubes can be extended or shortened, thereby facilitating the patient to adjust their posture without pulling the hemodialysis tubes, and making the use more flexible.
[0016] In the present invention, the hemodialysis tube can be stably reinforced, and the hemodialysis tube will not be squeezed during the reinforcement process, thereby avoiding bending and squeezing of the hemodialysis tube during use, thereby affecting the drainage and reflux effects of the blood, and ensuring stable use of the hemodialysis tube.

DETAILED DESCRIPTION
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0025] See also Figures 1 to 6 The present invention provides a technical solution: a hemodialysis tube fixing and protective cover device for hemodialysis, comprising an annular plate 1, one end of the annular plate 1 is fixedly connected to a first strap 2, the other end of the annular plate 1 is fixedly connected to a second strap 3, a horizontally slidable extension plate 4 is provided inside the annular plate 1, a mounting seat 5 is fixed on the top of the annular plate 1 and the extension plate 4, an adjustable reinforcement ring 6 is installed in the middle of the mounting seat 5, and a hemodialysis tube 8 is clamped in the middle of the reinforcement ring 6.
[0026] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a flexible air-permeable pad 102 is glued to the inner wall of the annular plate 1 .
[0027] It should be noted that the flexible breathable pad 102 is a latex pad, which has good breathability and can effectively discharge excess heat and moisture. At the same time, it is equipped with multiple breathable pores inside. When the protective device is installed on the human arm, the heat generated can be discharged through the breathable holes. In addition, the flexible breathable pad 102 has high elasticity, which can increase its softness when tied to the patient's arm to avoid squeezing and affecting the comfort of use.
[0028] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the outer wall of the first strap 2 is glued with the Velcro hook surface 21, and the inner wall of the second strap 3 is glued with the Velcro felt surface 31, and the Velcro hook surface 21 and the Velcro felt surface 31 are bonded.
[0029] It should be noted that the first binding strap 2 and the second binding strap 3 are elastic bands with elastic properties so that they will not be tight during the binding process.
[0030] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a fixed block 41 is fixed inside the annular plate 1, and a screw 42 is rotatably connected to the end side of the fixed block 41. A rocker 43 is fixed to the end side of the screw 42. A sliding rod 44 is sleeved on the external thread of the screw 42. A mounting block 45 is fixed to the end side of the sliding rod 44. A telescopic rod 46 is fixedly connected between the mounting block 45 and the fixed block 41.
[0031] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a sliding groove 101 is provided inside the annular plate 1 to facilitate horizontal sliding of the extension plate 4 .
[0032] It should be noted that an extension plate 4 is installed inside the annular plate 1. During the process of reinforcing the hemodialysis tube, the reinforcement positions of the two reinforcement rings 6 can be adjusted according to the length of the hemodialysis tube 8, so that both ends of the hemodialysis tube 8 can be reinforced when reinforcing, so that the force during reinforcement is stable and uniform.
[0033] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a support block 61 is fixed to the inner wall of the mounting base 5, and there are two support blocks 61. A support rod 62 is fixedly connected between the two support blocks 61. A slider 63 is slidably sleeved on the outside of the support rod 62. There are two sliders 63. A spring 64 is fixedly connected between the two sliders 63, and the spring 64 is sleeved on the support rod 62.
[0034] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a connecting rod 65 is hinged on the end side of the slider 63 , a connecting block 66 is hinged on the end side of the connecting rod 65 , and the connecting block 66 is fixedly connected to the reinforcement ring 6 .
[0035] It should be noted that there are two sliders 63, connecting rods 65, and connecting blocks 66. The two sliders 63 are symmetrically arranged about the axis of the support rod 62. The two sliders 63 slide inward or outward at the same time, and the clamping distance is adjusted by rotating the connecting rod 65, so that it can be suitable for hemodialysis tubes 8 of different specifications.
[0036] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, an anti-wear pad 7 is glued to the inner wall of the reinforcement ring 6 .
[0037] It should be noted that the anti-wear pad 7 has elasticity and anti-wear effects, so that the hemodialysis tube 8 can be cushioned when placed therein, avoiding squeezing of the hemodialysis tube 8 when it is clamped and reinforced, so that it can be used stably during the reinforcement process.
[0038] The use method and advantages of the present invention: When the hemodialysis tube fixing protective cover device is in operation, the working process is as follows:
[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, when using the protective cover device to fix and protect the hemodialysis tube, the annular plate 1 is first attached to the patient's arm, and the inner wall of the annular plate 1 is glued to the flexible breathable pad 102. When the annular plate 1 is installed on the human arm, the heat generated can be discharged through the ventilation holes in the flexible breathable pad 102. The flexible breathable pad 102 has high elasticity, which can improve its softness when tied to the patient's arm, avoiding squeezing and affecting the comfort of use.
[0040] Then, the first strap 2 is manually pulled to adhere the hook and loop surface 21 of the first strap 2 to the felt surface 31 of the second strap 3, so that the first strap 2 and the second strap 3 are tightly bound around the patient's arm. Then, the hemodialysis tube 8 is inserted into the reinforcement ring 6, so that the hemodialysis tube can be fixed to the patient's arm, solving the problem of discomfort and easy falling off caused by fixing with adhesive tape.
[0041] Then, the reinforcement position of the reinforcement ring 6 is adjusted according to the length of the hemodialysis tube 8. The rocker 43 is manually rotated to drive the screw 42 to rotate in the fixing block 41. When the screw 42 rotates, the sliding rod 44 with its external thread sleeve slides horizontally. At the same time, the telescopic rods 46 at both ends thereof extend and retract. As the sliding rod 44 continues to slide, the extension plate 4 installed on its end side through the mounting block 45 is placed in the slide groove 101 of the annular plate 1 and slides outward. The extension plate 4 then drives the reinforcement ring 6 installed on the top to move and thereby adjust the reinforcement position of the catheter, so that the length of the hemodialysis tube 8 can be adjusted when it is fixed, so that the reinforcement is stable.
[0042] After the adjustment is completed, the hemodialysis tube 8 is placed between the two reinforcement rings 6. During the placement of the hemodialysis tube 8, it will touch the reinforcement ring 6. The reinforcement ring 6 is forced to squeeze the connecting rod 65. The connecting rod 65 is forced to rotate and drive the two sliders 63 to slide horizontally along the outside of the support rod 62. When the two sliders 63 slide, they will squeeze the spring 64, causing the reinforcement ring 6 to expand so that the hemodialysis tube 8 can be placed therein. After it is completely placed, the spring 64 drives the reinforcement ring 6 to reset through its own elastic properties, so that the reinforcement ring 6 fits on both sides of the hemodialysis tube 8 to firmly clamp it, so that the hemodialysis tube 8 will not fall off during reinforcement, thereby improving the stability of the reinforcement, and an anti-wear pad 7 is installed inside the reinforcement ring 6. The anti-wear pad 7 can be used to buffer the hemodialysis tube 8 during reinforcement to avoid squeezing and bending the hemodialysis tube 8 when clamping it, thereby affecting the drainage and reflux effects of the blood.
[0043] When disassembling the device after use, tear off the hook and loop surface 21 of the first strap 2 to separate it from the felt surface 31 of the second strap 3, so that the two straps are separated and the device can be quickly removed without tearing the patient during the removal process.
