Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis pipeline positioning, and particularly relates to a bedside pipeline positioning and protection device for hemodialysis. Background Art

[0002] Hemodialysis (HD for short) is an important renal function replacement therapy for patients with acute and chronic renal failure. This process involves drawing the patient's blood out of the body through medical means and introducing it into a precisely designed dialysis device. Inside this dialyzer, there are thousands of tiny hollow fibers, forming a highly efficient mass exchange platform. During this process, the patient's blood flows inside the hollow fibers, while a special solution - dialysis fluid, which is similar to the body's electrolyte concentration, circulates outside the fibers.

[0003] Through complex physical and chemical mechanisms such as diffusion, ultrafiltration, adsorption, and convection, in-depth mass exchange occurs between the blood and the dialysis fluid on the inner and outer walls of the hollow fibers. This exchange process effectively removes the accumulated metabolic wastes in the blood, helps maintain the electrolyte balance and acid-base balance in the body, and ensures the stability of the internal environment. At the same time, it can also remove the excess water in the body, which is crucial for relieving the edema symptoms caused by renal failure. After completing the above purification steps, the treated blood is re-infused into the patient's body, thus realizing the replacement of partial renal functions. It should be noted that during hemodialysis treatment, in order to ensure the safety and efficiency of the treatment, it is usually necessary to accurately position and properly fix various pipelines connecting the patient and the dialysis machine to prevent pipeline displacement or detachment and ensure the smooth progress of the entire dialysis process.

[0004] For example, a bedside pipeline positioning and protection device for hemodialysis with the publication (announcement) number of CN112245163B includes a support plate. A first column is fixed on the upper side of the middle part of the first support plate. The upper right end of the first support plate is hinged with an extension plate to increase the bottom area and improve stability. The first column is a hollow tube, and a second column is arranged inside the tube. A connecting sleeve is sleeved outside the second column, and the connecting sleeve is connected to the upper end of the first column by threads. A first cross bar and a second cross bar are slidably connected to the second column. In the present invention, the randomly distributed pipelines are straightened by the arranged first cross bar, which is convenient for personnel to observe, and the clamping is convenient, with strong practicability. At the same time, by adjusting the positions of the various clamping parts and the convenient first cross bar and second cross bar, the pipelines are fixed on the window side by clips, and the pipelines are standardized on this device through the guide groove and the semi-circular piece, which provides convenience for medical staff to observe and adjust.

[0005] In summary, the following technical problems exist in the prior art: Although the above prior art can achieve the positioning of the pipeline during use, in actual use, due to the large volume of the device, it occupies a large space beside the hospital bed and is not convenient to flexibly arrange the number of positioning points as needed.

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Embodiment 1

[0033] Referring to Figures 1-5 , a bedside pipeline positioning and protection device for hemodialysis includes an auxiliary box 1 and a movable buckle 2 fixed on one side of the auxiliary box 1. A top shell 3 is fixed on the top of the auxiliary box 1. A positioning and protection mechanism is assembled between the auxiliary box 1 and the top shell 3. The positioning and protection mechanism is used to position the pipeline. The positioning and protection mechanism includes a first cylindrical rod 4, a cam 5, a handle 6 and a fitting assembly. First cylindrical rods 4 are fixed on both sides inside the auxiliary box 1. A cam 5 is rotatably connected to the outer side of the first cylindrical rod 4. A handle 6 is fixed on the top of the cam 5. A fitting assembly is assembled between the cam 5, the auxiliary box 1 and the top shell 3.

[0034] The fitting assembly includes a vertical connecting plate 7, a guiding groove 8, a cylindrical sliding rod 9, an arc-shaped through groove 10, a connecting rib column 11 and an auxiliary member. A vertical connecting plate 7 is assembled on the outer side of the first cylindrical rod 4. A guiding groove 8 is formed inside the vertical connecting plate 7. The guiding groove 8 is slidably connected to the first cylindrical rod 4. An arc-shaped through groove 10 is formed inside the cam 5. A cylindrical sliding rod 9 is slidably connected to the inside of the arc-shaped through groove 10. The cylindrical sliding rod 9 is fixed to the vertical connecting plate 7. A connecting rib column 11 is fixed on the top of the vertical connecting plate 7. The connecting rib column 11 is slidably connected to the top of the auxiliary box 1. An auxiliary member is assembled on the top of the connecting rib column 11. The top of the inside of the arc-shaped through groove 10 is a force application surface, which can apply pressure to the cylindrical sliding rod 9 when the cam 5 rotates, so that the cylindrical sliding rod 9 drives the vertical connecting plate 7 to move downward.

[0035] The auxiliary member includes a U-shaped plate 12, a trapezoidal block 13, a fixed guiding platform 14, a track groove 15, a second cylindrical rod 18, a top head 20, a first semi-circular arc plate 22 and a second semi-circular arc plate 23. A U-shaped plate 12 is fixed on the top of the connecting rib column 11. A trapezoidal block 13 is rotatably connected to the inside of the U-shaped plate 12 through a second cylindrical rod 18. One end of the top of the auxiliary box 1 is fixed with a fixed guiding platform 14. A track groove 15 is formed inside the fixed guiding platform 14. The track groove 15 is slidably connected to the trapezoidal block 13. A top head 20 is fixed on the top of the trapezoidal block 13. An extension rod is fixed inside the top head 20. One end of the extension rod is fixed with a first semi-circular arc plate 22. The other end of the top of the auxiliary box 1 is fixed with a second semi-circular arc plate 23. The second semi-circular arc plate 23 is fixed to the auxiliary box 1 in a detachable manner, which is convenient for replacing the second semi-circular arc plates 23 of different specifications for subsequent use.

[0036] A horizontal groove 16 and a vertical groove 17 are provided on the inner side of the track groove 15. The horizontal groove 16 and the vertical groove 17 are connected. Both the horizontal groove 16 and the vertical groove 17 are slidably connected to the trapezoidal block 13. When the trapezoidal block 13 is pulled downward by the U-shaped plate 12, the trapezoidal block 13 moves along the inner side of the horizontal groove 16. When it moves to the connection between the horizontal groove 16 and the vertical groove 17, at this time, the trapezoidal block 13 starts to be guided to rotate and gradually enters the vertical groove 17. When the trapezoidal block 13 is completely separated from the horizontal groove 16, at this time, the trapezoidal block 13 flips 90°.

[0037] A torsion spring 19 is sleeved on the outer side of the second cylindrical rod 18. One end of the torsion spring 19 is fixed to the second cylindrical rod 18, and the other end of the torsion spring 19 is fixed to the U-shaped plate 12. Through the setting of the torsion spring 19, when the handle 6 is released, it is convenient for the second cylindrical rod 18 to drive the trapezoidal block 13 to rotate back to its original position, so that the trapezoidal block 13 drives the top head 20 and the first semi-circular arc plate 22 to return to their original positions, that is, the positioning of the pipeline can be quickly released.

[0038] Temperature increasing modules are arranged on the inner sides of the first semi-circular arc plate 22 and the second semi-circular arc plate 23. One end of the top shell 3 is fixed with a controller 21. The controller 21 is electrically connected to the temperature increasing module through a wire. The temperature increasing module is ST021. The cooperation working principle of the controller 21 and the temperature increasing module is as follows: The controller 21 is configured with a temperature sensor, and the temperature sensor monitors the ambient temperature in real time and feeds back the signal to the controller. The controller compares the feedback signal with the preset temperature value to judge whether it is necessary to adjust the working state of the temperature increasing module. When the controller judges that it is necessary to adjust the working state of the temperature increasing module, it will output a control instruction through the output unit. These instructions are received and executed by the temperature increasing module, so as to adjust its heating power and temperature. The entire temperature increasing control system usually constitutes a closed-loop control system. In this system, the controller continuously receives the feedback signal of the temperature sensor and adjusts the working state of the temperature increasing module according to the feedback signal to achieve precise temperature control. This closed-loop control method can greatly improve the stability and reliability of the system. It can prevent the blood temperature from dropping due to the influence of the ambient temperature during the extracorporeal circulation process, and avoid causing discomfort or even complications to the patient.

[0039] Embodiment 2

[0040] Further optimize Embodiment 1. Specifically, as Figures 6-7 shown, a displacement prevention mechanism is assembled on one side of the auxiliary box 1. The displacement prevention mechanism is used to limit the vertical connecting plate 7.

[0041] The anti-displacement mechanism includes a fixed sleeve 24, a first quadrilateral frame 25, a second quadrilateral frame 26, a mating post 27, a mating groove 28, a double-headed plate 29, a resistance rod 30, and a rack 31. A fixed sleeve 24 is fixed to one side of the auxiliary box 1. The first quadrilateral frame 25 and the second quadrilateral frame 26 are slidably connected to the inside of the fixed sleeve 24. One ends of the first quadrilateral frame 25 and the second quadrilateral frame 26 are connected by a spring. A mating post 27 is fixed to the bottom inside the second quadrilateral frame 26. One side of the bottom of the first quadrilateral frame 25 is rotatably connected to a double-headed plate 29. The double-headed plate 29 is rotatably connected to the fixed sleeve 24 by a pin. A mating groove 28 is formed at one end of the double-headed plate 29. The mating groove 28 is in interference fit with the mating post 27. A resistance rod 30 is fixed to the end of the second quadrilateral frame 26 away from the spring. The resistance rod 30 is slidably connected to the fixed sleeve 24 and the auxiliary box 1. A rack 31 is fixed to one side of the vertical connecting plate 7. The rack 31 is meshed with the resistance rod 30. Through the arrangement of the resistance rod 30, the position of the rack 31 can be limited, and thus the vertical position of the vertical connecting plate 7 can be limited.

[0042] The anti-displacement mechanism further includes a blocking block 32. The blocking block 32 is fixed to the bottom inside the fixed sleeve 24 at a position corresponding to the first quadrilateral frame 25. Through the arrangement of the blocking block 32, the stroke of the first quadrilateral frame 25 can be limited, so that the user can adjust the position of the resistance rod 30 without pressing the first quadrilateral frame 25 to the bottom.

[0043] From the above, it can be seen that:

[0044] In view of the technical problem of the present invention: In the prior art, although the positioning of the pipeline can be achieved during use, in actual use, due to the large volume of the device, it occupies a large space beside the hospital bed, and it is not convenient to flexibly arrange the number of positioning points according to needs. The technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is as follows:

[0045] During use, first, the movable buckle 2 of multiple devices is clamped on the hospital bed guardrail. Then, the pipeline is placed inside the second semi-circular plate 23. Next, the first quadrilateral frame 25 is pressed, so that the first quadrilateral frame 25 pushes the double-headed plate 29 to rotate. Since the double-headed plate 29 is in interference fit with the mating column 27 through the mating groove 28, the first quadrilateral frame 25 and the second quadrilateral frame 26 are connected by a spring, and the second quadrilateral frame 26 is fixed to the resistance rod 30, it is possible to make the mating groove 28 pull the mating column 27 to drive the second quadrilateral frame 26 to move, so that the spring is squeezed and contracted. Furthermore, the second quadrilateral frame 26 drives the resistance rod 30 to separate from the rack 31. Then, the handle 6 is pressed, so that the handle 6 drives the cam 5 to rotate along the outer side of the first cylindrical rod 4. Under the guidance of the arc-shaped through groove 10, the cylindrical slide rod 9 is dragged downward. Thus, the vertical connecting plate 7 drives the U-shaped plate 12 and the rack 31 to move downward synchronously. Also, since the U-shaped plate 12 is rotatably connected to the trapezoidal block 13 through the second cylindrical rod 18, and the trapezoidal block 13 is slidably connected to the horizontal groove 16 and the vertical groove 17, it is possible to make the trapezoidal block 13 drive the top head 20 and the extension rod to turn under the guidance of the horizontal groove 16 and the vertical groove 17 until the first semi-circular plate 22 moves downward to limit and position the pipeline located inside the second semi-circular plate 23. Finally, the first quadrilateral frame 25 is released, so that the resistance rod 30 is connected to the rack 31 again.

[0046] Through the above settings, this application will surely solve the above technical problems. At the same time, the following technical effects are achieved:

[0047] 1. Through the structural design of the positioning protection mechanism and the anti-displacement mechanism, the device of the present invention is convenient for positioning and protecting the hemodialysis pipeline. At the same time, it can be small in size, facilitating medical staff to flexibly arrange the number of positioning points according to needs, that is, multiple auxiliary boxes 1 are used to achieve multi-point arrangement of the pipeline, without occupying space, improving work efficiency, and enhancing the flexibility of the device.

[0048] 2. Through the structural design of the controller 21 and the temperature-raising module, the device of the present invention can perform constant-temperature preheating on the pipeline during the hemodialysis process, and can continuously and stably provide appropriate temperature support for the flowing pipeline and the blood therein, reducing the possible physiological reactions of patients caused by temperature changes, and providing a safer and more comfortable treatment experience for patients.
