Description

Technical Field

[0002] Blood purification is also known as hemodialysis in medical treatment. 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 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. The whole process is called hemodialysis. Hemodialysis requires multiple pipes for dialysis in the medical process. There are a large number of pipes, and fixed devices are required to clear the pipes.

[0003] The blood purification fixtures used in the prior art are mostly external, and are generally placed on the ground to pass the pipelines through their through holes to straighten the pipelines. When in use, the fixture needs to be placed in a specified position and the angle needs to be adjusted, and then the pipelines need to be straightened. The fixture needs to be stored after use. During the hemodialysis process, the staff needs to observe the dialysis situation all the time, so the fixture on the ground occupies a certain area. If the medical staff accidentally touches the fixture, the angle of the fixture is easily offset, and then the pipeline is easily bent, affecting the transportation of blood and dialysate. At the same time, it is inconvenient for the medical staff to move around, affecting the medical staff's observation. Utility Model Content

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1-Figure 3 The utility model discloses a pipeline fixing device for blood purification care, including a mounting plate 1, a splint 2 is fixedly mounted on the side of the mounting plate 1, the splint 2 is U-shaped, a gear shaft 3 is rotatably mounted between the top and bottom sides of the splint 2, a spring sheet 4 is fixedly mounted on the inner side wall of the splint 2, the spring sheet 4 is processed to form an arc surface on the side close to the gear shaft 3 and extends into the tooth groove of the gear shaft 3, a support rod 5 is fixedly connected to the outer peripheral wall of the gear shaft 3, a limiting groove 6 is provided at one end of the support rod 5 away from the gear shaft 3, a support assembly 7 is installed in the limiting groove 6, and a fixing part 8 is installed on the top side of the support rod 5.

[0029] In this embodiment, during installation, the mounting plate 1 is glued to a suitable position on the dialysis machine by means of waterproof latex, and then the support rod 5 is limitedly rotated during use, so that the support rod 5 drives the gear shaft 3 to rotate. When the support rod 5 is manually turned, a force greater than the limit of the spring piece 4 is required, and then after turning to a suitable angle, the turning of the support rod 5 is stopped, so that the gear shaft 3 is limited by the spring piece 4 again, to prevent the support rod 5 from changing its angle due to pulling the pipeline during use, and then the fixing piece 8 is turned or pushed, so that the fixing piece 8 slides or rotates on the support assembly 7 to adjust the angle and position required for fixing the pipeline, and after the angle and position of the fixing piece 8 are adjusted, the fixing piece 8 is stopped. 8 is toggled, and then the dialysis pipeline is fixed by the fixing member 8 to prevent the pipeline from being deviated or bent due to collision during use, affecting the dialysis work. The fixing device is directly installed on the dialysis machine when in use. After the pipeline on the dialysis machine is connected, the pipeline fixing device can be quickly unfolded and the pipeline on the dialysis machine can be fixed, which reduces the floor space and is convenient for medical staff to use. It can also ensure that the pipeline fixing device is within the field of vision of medical staff to the greatest extent, which is convenient for medical staff to observe the pipeline, reduces the probability that the fixed pipeline of the dialysis machine is accidentally touched by medical staff during use, affecting the normal operation of the dialysis machine, increases the safety of the dialysis machine when in use, and improves the portability of the fixing device.

[0030] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the support assembly 7 includes two tooth plates 9, which are respectively installed on the two side walls in the limiting groove 6. A sliding groove 10 is opened in the middle of the top side of the support rod 5, and the width of the sliding groove 10 is smaller than the distance between the two tooth plates 9.

[0031] In this embodiment, after the angle of the support rod 5 is adjusted, the tooth plate 9 is used to limit the fixing member 8 during use, and the tooth grooves in the tooth plate 9 are all set to be serrated, which facilitates limiting and prevents the fixing member 8 from being stuck when moving or rotating.

[0032] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a slide rod 11 is slidably installed in the slide groove 10, and the bottom end of the slide rod 11 extends into the limit groove 6. A number of empty grooves 12 are opened on the bottom side of the outer peripheral wall of the slide rod 11, and a limit rod 13 is piston-connected in several of the empty grooves 12. The end of the limit rod 13 is processed to form an arc surface, wherein the arc surface end of the limit rod 13 close to the tooth plate 9 is in contact with the tooth plate 9.

[0033] In this embodiment, the fixing member 8 is installed as a whole at the top of the slide bar 11. When the fixing member 8 is rotated at an angle, the fixing member 8 is directly turned, so that the fixing member 8 drives the slide bar 11 to rotate. At this time, the limiting rod 13 will be subjected to the force of the slide bar 11 and rotate along with it, and then it will be limited by the tooth groove on the tooth plate 9. The tooth groove of the tooth plate 9 is serrated, so the arc surface formed by the limiting rod 13 will be gradually compressed along the tooth groove on the tooth plate 9, and then compressed into the empty groove 12, so that the slide bar 11 can slide in the limiting groove 6 under a certain force;

[0034] When it is necessary to move the fixing part 8, the fixing part 8 is directly pushed or pulled, thereby driving the sliding rod 11 to move. The sliding rod 11 will drive the limiting rod 13 to move, and the limiting rod 13 will be limited by the tooth groove of the tooth plate 9. After the pushing or pulling force is greater than the limiting force, the tooth groove side wall of the tooth plate 9 will squeeze the limiting rod 13, so that the limiting rod 13 is squeezed into the empty groove 12. After the movement or rotation of the fixing part 8 is adjusted, the air pressure in the empty groove 12 will squeeze the limiting rod 13 out, thereby inserting it into the tooth groove of the tooth plate 9 and re-limiting it to prevent the position and angle of the fixing part 8 from being offset when the dialysis pipeline is pulled during use.

[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the fixing member 8 includes a hollow square tube 14, which is fixedly mounted on the top of the sliding rod 11, and a piston in the hollow square tube 14 is connected to a rectangular frame 15, and a threaded rod 16 is rotatably mounted on one end of the hollow square tube 14 away from the splint 2, and the threaded rod 16 extends into the hollow square tube 14 and is threadedly connected to the end of the rectangular frame 15.

[0036] In this embodiment, the hollow square tube 14 is used together with the sliding rod 11 when in use, and the hollow square tube 14 is the main support of the entire fixing member 8. In addition, when fixing the pipeline, the threaded rod 16 is rotated so that the threaded rod 16 drives the rectangular frame 15 to perform piston movement in the hollow square tube 14, providing fixing power for the fixing member 8 to fix the pipeline.

[0037] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a positioning rod 17 is fixedly connected to the top side of the hollow square tube 14, and a plurality of fixing grooves 18 are opened on the top side of the positioning rod 17, wherein an air delivery hole 19 is opened at the bottom of the fixing groove 18 close to the clamping plate 2, and the air delivery hole 19 is connected to the hollow square tube 14, and a connecting hole 20 is opened between two adjacent fixing grooves 18.

[0038] In this embodiment, the positioning rod 17 is set, when the threaded rod 16 rotates to drive the piston of the rectangular frame 15 to move, the air in the hollow tube will enter the fixing groove 18 through the air delivery hole 19, and then the air bag fixing the pipeline is fixed by using multiple fixing grooves 18.

[0039] In a further preferred embodiment of the present invention, Figure 1-3 As shown, several of the fixing grooves 18 are fixedly installed with airbag columns 21, and the airbag columns 21 located on the top side of the air delivery hole 19 are connected to the air delivery hole 19. A connecting airbag 22 is arranged in each of the connecting holes 20, and the two ends of the connecting airbag 22 are respectively connected to the corresponding airbag columns 21. The top end of the airbag column 21 is connected to a C-shaped airbag 23, and the inner peripheral wall of the C-shaped airbag 23 is connected to a number of convex airbags 24.

[0040] In this embodiment, after air enters the fixing groove 18, the airbag column 21 connected to the air delivery hole 19 will gradually expand, and then the multiple airbag columns 21 will be expanded after being injected with air through the connecting airbag 22, and the C-shaped airbag 23 connected to each airbag column 21 will also expand accordingly. When the C-shaped airbag 23 is not fully expanded, the pipeline of the dialysis machine is passed through the C-shaped airbag 23 and connected to the corresponding place, and then the threaded rod 16 is continuously rotated so that the threaded rod 16 drives the piston movement of the rectangular frame 15, and the airbag column 21 and the C-shaped airbag 23 are continuously injected with air, and finally the convex airbag 24 installed on the C-shaped airbag 23 will expand and clamp the dialysis machine pipeline passing through;

[0041] After clamping, the pipeline is prevented from being deformed by pulling, and the deformation of the pipeline is avoided to avoid damage to the pipeline after deformation, which affects the use of dialysis. After use, the threaded rod 16 is rotated to drive the rectangular frame 15 to reset, and the airbag column 21, the connecting tube airbag and the C-shaped airbag 23 will be evacuated, and after being deflated, they can be directly compressed and inserted into the fixing groove 18. After being inserted, they are in the same position as in this embodiment. Figure 1 The shape of the compressed air bag 1001 shown in the figure closes the fixing groove 18, so that it does not occupy the ground space when in use, and can be directly stored for convenient use with the dialysis machine, thereby increasing practicality.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
