Description

Technical Field

[0001] The invention relates to the technical field of fixing devices, in particular to a hemodialysis pipeline fixing device for treating renal failure. 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 and passes it 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 inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection to remove metabolic waste from the body and maintain electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. Hemodialysis is performed to facilitate the management of multiple dialysis lines, and the dialysis lines are arranged and fixed on the line fixture.

[0003] The traditional pipe fixing device is a back plate with multiple guide cylinders. The pipes are arranged on the back plate by winding. The guide cylinders can prevent pipe bending and interruption. However, since there are many guide cylinders fixed on the surface, when the pipes are arranged, the redundant guide cylinders are likely to affect the direction of the pipes. After the direction is restricted, the length of the pipes must be considered during arrangement, resulting in some pipes being unable to be fixed on the back plate, greatly reducing the applicability of the fixing device.

[0027] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Reference Figures 1 to 4 A hemodialysis pipeline fixing device for treating renal failure, the pipeline fixing device comprises a pipeline back plate 1 and a mounting socket 2, a plurality of mounting sockets 2 are equidistantly provided inside the pipeline back plate 1, the thickness of each mounting socket 2 is equal to the thickness of the pipeline back plate 1, and the first limit plate 7 and the movable inner rod 6 are convenient to penetrate the mounting socket 2, a plurality of mounting sockets 2 are provided with fixing components on the front side, and a mounting component is provided on the rear side of the pipeline back plate 1;

[0029] The fixing assembly includes a rear pad 3, a front pad 4, a pipeline guide cylinder 5, a movable inner rod 6, a first limit plate 7 and a spring 8. A plurality of rear pads 3 are arranged on the front side of the mounting holes 2. The length of each rear pad 3 is greater than the length of the mounting hole 2, so that the rear pad 3 can be abutted against the pipeline back plate 1. In cooperation with the first limit plate 7, the rear pad 3 can be fixed on the pipeline back plate 1, and a front pad 4 is fixed at the center position of one end of the rear pad 3 away from the pipeline back plate 1. Each front pad 4 is fixed on one side away from the rear pad 3. A movable inner rod 6 is slidably sleeved inside the guide cylinder 5, and each movable inner rod 6 is set to a horizontally placed "T" shape. One end of each movable inner rod 6 located inside the pipeline guide cylinder 5 is set to a rectangle to prevent the pipeline guide cylinder 5 and the movable inner rod 6 from rotating relative to each other. Under the cooperation and limitation of the first limit plate 7, the pipeline guide cylinder 5 is prevented from rotating after being installed on the pipeline back plate 1. One end of each movable inner rod 6 located inside the pipeline guide cylinder 5 is set to a rectangle to facilitate the horizontal movement of the movable inner rod 6 inside the pipeline guide cylinder 5 and the rear pad 3. A spring 8 is sleeved on the movable inner rod 6 inside the pipeline guide cylinder 5, and both ends of the spring 8 are respectively fixed on the pipeline guide cylinder 5 and the movable inner rod 6. A first limit plate 7 is fixed to one end of each movable inner rod 6 extending to the outside of the pipeline back plate 1. Each first limit plate 7 and the second limit plate 15 are designed to be circular in the middle and symmetrically rectangular at both ends to match the fixed through hole 12. An arc groove 10 is opened on the symmetrical arc section of each first limit plate 7. When the rear pad 3 is disassembled, the first limit plate is held by the arc groove 10. 7 is more convenient. A limiting card slot 9 is provided on the pipeline back plate 1 at the left and right ends of the rear side of each mounting socket 2, and the thickness of the limiting card slot 9 is equal to the thickness of the first limiting plate 7, so that when the first limiting plate 7 passes through the mounting socket 2, it can be engaged with the limiting card slot 9 after being rotated to be aligned with the limiting card slot 9, thereby ensuring the stability of the connection between the rear pad 3 and the pipeline back plate 1. Each limiting card slot 9 is cross-designed with the rectangles at both ends of the mounting socket 2 in a "cross" shape, so that when the first limiting plate 7 is aligned with the limiting card slot 9, it can be misaligned with the rear pad 3.

[0030] Specifically, when arranging the pipeline, first hang the pipeline on the pipeline guide cylinder 5, and then pull the first limit plate 7, so that the first limit plate 7 drives the moving inner rod 6 to be compressed away from the rear pad 3, and the first limit plate 7 is aligned with the installation hole 2, so that the first limit plate 7 passes through the installation hole 2. After the first limit plate 7 passes through the pipeline back plate 1, the rear pad 3 is rotated to drive the first limit plate 7 to rotate until it is misaligned with the installation hole 2, and then the first limit plate 7 is released so that the first limit plate 7 abuts against the inside of the limit slot 9 under the pull of the spring 8. The first limit plate 7 can cooperate with the rear pad 3, and the pipeline back plate 1 can be clamped under the push of the spring 8, so that the pipeline guide cylinder 5 can be installed on the pipeline back plate 1, so as to limit the pipeline. The pipeline back plate 1 without the pipeline guide cylinder 5 assembled will not affect the arrangement direction of the pipeline.

[0031] As an optimization solution, Figure 3 and Figure 4 As shown, a plurality of pipeline binding straps 11 are fixed equidistantly on the rear pad 3 outside each pipeline guide cylinder 5, and the width of each pipeline binding strap 11 is greater than the sum of the widths of the pipeline guide cylinder 5 and the pipeline binding strap 11, ensuring that the pipeline binding strap 11 can pass through the fixed perforation 12 and be bonded and fixed on the Velcro mother patch 14, thereby ensuring that the pipeline binding strap 11 can limit the pipeline, and a plurality of fixed perforations 12 cooperating with the pipeline binding strap 11 are equidistantly opened inside each front pad 4, and each fixed perforation 12 is set to be cooperating with the Velcro mother patch 14. The arc shape of the mother patch 14 facilitates the pipeline strap 11 to pass through the fixed perforation 12, and prevents the fixed perforation 12 from affecting the bonding and fixation of the Velcro sub-patch 13 and the Velcro mother patch 14. The inner side of each pipeline strap 11 extending to the front end of the fixed perforation 12 is glued and fixed with a Velcro sub-patch 13, and the front center position of each front pad 4 is glued and fixed with a Velcro mother patch 14. The diameter of each Velcro mother patch 14 is larger than the diameter of the pipeline guide tube 5, which facilitates the bonding and fixation of the Velcro sub-patch 13 and the Velcro mother patch 14.

[0032] Specifically, after the pipeline is wrapped around the pipeline guide cylinder 5, the pipeline tie 11 on the side where the pipeline and the pipeline guide cylinder 5 are in contact is tied to the outside of the pipeline, and then the pipeline tie 11 is passed through the fixing through hole 12 and fixed to the Velcro mother patch 14 through the Velcro sub-patch 13, so that the pipeline and the pipeline guide cylinder 5 can be fixed, making the connection between the pipeline and the pipeline guide cylinder 5 more stable, thereby improving the stability of the fixing device when in use.

[0033] As a further optimization solution, Figure 5As shown, the installation assembly includes a second limiting plate 15, a connecting screw 16, a support plate 17, a first clamping block 18, a support screw 19, a mounting plate 20 and a second clamping block 21. The support plate 17 is symmetrically arranged on one side of the pipeline back plate 1 away from the rear pad 3. Each support plate 17 is arranged in a horizontally placed "U" shape, which is convenient for the mounting plate 20 to rotate inside the support plate 17. A connecting screw 16 is fixed at the center position of one end of each support plate 17 close to the pipeline back plate 1. The thickness of each connecting screw 16 is equal to the sum of the thickness of the pipeline back plate 1 and the first clamping block 18, ensuring that the first clamping block 18 can be screwed to separate from the pipeline back plate 1, thereby facilitating the rotation of the connecting screw 16. The thickness of each connecting screw 16 is equal to the sum of the thickness of the pipeline back plate 1 and the first clamping block 18, which is convenient for the connecting screw 16 to pass through the mounting jack 2, and the second limiting plate 15 is fixed to the end of the connecting screw 16 extending to the front side of the pipeline back plate 1. The connecting screws 16 on the side are all threadedly sleeved with a first clamping block 18, and the length of each first clamping block 18 is greater than the length of the mounting socket 2. The first clamping block 18 is used to limit the connection screw 16, so that the connecting screw 16 can be fixedly installed on the mounting socket 2, and a support screw 19 is fixed inside each support plate 17, and a mounting plate 20 is rotatably sleeved on the support screw 19, and each mounting plate 20 is provided with a rotation hole that matches the support screw 19 at one end close to the support plate 17, and the outer ring diameter of each second clamping block 21 is greater than the diameter of the rotation hole, which is convenient for the mounting plate 20 to rotate on the support screw 19, and the outer ring diameter of each second clamping block 21 is greater than the diameter of the rotation hole, ensuring that the second clamping block 21 can clamp and fix the mounting plate 20, and each mounting plate 20 is provided with a mounting hole at one end away from the support plate 17, which is convenient for fixing and installing the pipeline back plate 1, and the pipeline back plate 1 on the side of each mounting plate 20 is threadedly sleeved with a second clamping block 21.

[0034] Specifically, when installing the pipeline back plate 1, according to the position of the pipeline back plate 1 when it is installed, the second limit plate 15 is aligned with the corresponding mounting hole 2 and passed through the mounting hole 2. When the middle part of the pipeline back plate 1 needs to be connected to the dialyzer, the second limit plate 15 can be passed through the mounting hole 2 in the middle. After the second limit plate 15 passes through the mounting hole 2, it is rotated to be misaligned with the mounting hole 2, and then the connecting screw 16 is screwed to abut against the pipeline back plate 1, so that the connecting screw 16 can be fixed to the pipeline back plate 1, and the mounting plate 20 is fixed to the dialyzer or the bed by bolts, and then the second clamping block 21 is screwed to loosen the clamping of the second clamping block 21 on the mounting plate 20, and the pipeline back plate 1 can be rotated. After the rotation is completed, the second clamping block 21 is screwed again to clamp and fix the mounting plate 20, which is convenient for installing the pipeline back plate 1 and adjusting the installation angle.
