This can easily lead to problems such as tangling and knotting of the dialysis tubing during subsequent use, affecting the smooth progress of dialysis treatment. Therefore, those skilled in the art provide a dialysis tubing coiling machine to solve the problems mentioned in the background art. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution: a dialysis tubing coiling machine, including a workbench 1, a first sliding groove 101 is provided on one side of the top of the workbench 1, four sets of limiting grooves 102 are symmetrically provided on the top of the workbench 1, the four sets of limiting grooves 102 are located at the four corners of the top of the workbench 1, a second sliding groove 103 is provided at both ends of the inner wall of the bottom of the workbench 1, an installation groove 104 is provided at the center of the inside of the workbench 1, and a tubing clamping mechanism 2 for clamping dialysis tubing is provided at the top of the workbench 1. The system includes a slide rod 201 installed inside the first slide groove 101. Slide sleeves 202 are slidably installed at both ends of the slide rod 201. A return spring 203 is fitted between the slide rod 201 and the two sets of slide sleeves 202. The two ends of the return spring 203 are fixedly connected to the inner walls of the two sets of slide sleeves 202 respectively. A slide seat 204 is fixedly installed at the top of each set of slide sleeves 202. Both sets of slide seats 204 are vertically located on one side of the top of the worktable 1. Multiple sets of clamping rollers 205 are rotatably installed on the inner side of the bottom end of each set of slide seats 204.

[0023] The first slide groove 101 facilitates the installation of the slide rod 201 inside. The four sets of limiting grooves 102, in conjunction with the four sets of second connecting rods 306 and other components, ensure the stability and accuracy of the side limiting mechanism 3 during movement, preventing it from shifting or shaking. The second slide groove 103 provides a sliding track for the side limiting mechanism 3 or other related components, allowing for smooth position adjustment. The installation groove 104 facilitates the installation of key components such as the coiling mechanism 4, making the structure of the entire coiling machine more compact and reasonable. The dialysis tube is placed between several sets of clamping rollers 205 in pairs. The elastic force of the return spring 203 causes the two sets of sliding sleeves 202 to move relative to each other on the surface of the slide rod 201, thereby driving the two sets of sliding seats 204 and several sets of clamping rollers 205 to move relative to each other on the top of the worktable 1, facilitating the elastic clamping of the several sets of clamping rollers 205 according to the diameter of the dialysis tube.

[0024] As one implementation method in this embodiment, please refer to Figure 1 and Figure 3 As shown, the top of the workbench 1 is equipped with a side limiting mechanism 3 for limiting the side of the dialysis tube. The side limiting mechanism 3 includes a cylinder 301 installed at the bottom of the workbench 1. A connecting plate 302 is fixedly connected to the bottom of the cylinder 301. Connecting rods 303 are fixedly connected to both ends of the connecting plate 302. Slider 304 is fixedly connected to the ends of the two sets of connecting rods 303 away from the two sets of connecting plates 302. The two sets of sliders 304 are slidably installed inside the two sets of second sliding grooves 103 respectively. The sidewall of the connecting plate 302 is connected to four sets of... The first link 305, and the four sets of first links 305 are respectively located at the center of the four sides of the connecting plate 302. The ends of the four sets of first links 305 away from the connecting plate 302 are all hinged to the second links 306. The four sets of second links 306 are slidably arranged inside the four sets of limiting grooves 102. The top of the four sets of second links 306 are all fixedly connected to the spring rods 307. The ends of the spring rods 307 away from the second links 306 are all fixedly connected to the arc-shaped limiting plates 308. The four sets of arc-shaped limiting plates 308 are distributed in a circular array on the outside of the coil mechanism 4.

[0025] By activating cylinder 301, the connecting plate 302 is raised and lowered. It should be noted that the two sets of sliders 304 slide inside the two sets of second sliding grooves 103, and the two sets of second connecting rods 306 drive the connecting plate 302 to move smoothly up and down at the bottom of the worktable 1. The raised and lowered connecting plate 302 drives the four sets of first connecting rods 305 to rotate synchronously through the hinge. The four sets of synchronously rotating first connecting rods 305 drive the four sets of second connecting rods 306 to slide parallel inside the four sets of limiting grooves 102 through the hinge. The four sets of parallel sliding second connecting rods 306 drive the four sets of spring rods 307 and the four sets of arc-shaped limiting plates 308 to slide parallel at the four corners of the top of the worktable 1. This allows the four sets of arc-shaped limiting plates 308 to adjust the width of the dialysis tube coil, thereby limiting the required width of the dialysis tube coil. At the same time, the elastic force of the four sets of spring rods 307 allows the four sets of arc-shaped limiting plates 308 to be adaptively adjusted according to the diameter of the dialysis tube coil.

[0026] As one implementation method in this embodiment, please refer to 1 and Figure 5 As shown, a coiling mechanism 4 for dialysis tubing is provided at the center of the top of the workbench 1. The coiling mechanism 4 includes a winding roller 401 rotatably mounted at the center of the top of the workbench 1. A pressure plate 402 is slidably fitted on the surface of the winding roller 401. A top plate 403 is fixedly connected to the top of the winding roller 401. The top plate 403 is located above the pressure plate 402. An electric telescopic rod 404 is fixedly installed on one side of the top ...

[0027] By activating the electric telescopic rod 404 to extend and retract, the pressure plate 402 moves up and down on the surface of the winding roller 401, adjusting the position of the pressure plate 402 on the surface of the winding roller 401. This allows for adjustment of the height of the dialysis tubing coil. Once the height of the pressure plate 402 is adjusted, the operator manually winds one end of the dialysis tubing around the surface of the winding roller 401. Then, the motor 406 is activated, causing the winding roller 401 to rotate. The pressure plate 402 then limits the height of the dialysis tubing coil.

[0028] Working principle: In use, the dialysis tube is first placed between several sets of clamping rollers 205 facing each other. The elastic force of the return spring 203 causes the two sets of sliding sleeves 202 to move relative to each other on the surface of the sliding rod 201, thereby driving the two sets of sliding blocks 204 and several sets of clamping rollers 205 to move relative to each other on the top of the worktable 1, so that the several sets of clamping rollers 205 can elastically clamp the dialysis tube according to the diameter of the tube.

[0029] After several sets of clamping rollers 205 have completed the elastic clamping of the dialysis tube, cylinder 301 is activated. Cylinder 301 drives the connecting plate 302 to rise and fall. It should be noted that through the sliding of two sets of sliders 304 inside two sets of second sliding grooves 103, and through two sets of second connecting rods 306, the connecting plate 302 is driven to move smoothly up and down at the bottom of the worktable 1. The rising and falling connecting plate 302 drives four sets of first connecting rods 305 to rotate synchronously through the hinge. The four sets of synchronously rotating first connecting rods 305 are connected by the hinge. The four sets of second connecting rods 306 slide parallel inside the four sets of limiting grooves 102. The four sets of parallel sliding second connecting rods 306 drive the four sets of spring rods 307 and the four sets of arc-shaped limiting plates 308 to slide parallel at the four corners of the top of the worktable 1. This allows the four sets of arc-shaped limiting plates 308 to adjust the width of the dialysis tube coil, thereby limiting the required width of the dialysis tube coil. At the same time, the four sets of arc-shaped limiting plates 308 can be adaptively adjusted according to the size of the dialysis tube coil diameter through the elastic force of the four sets of spring rods 307.

[0030] After the four sets of arc-shaped limiting plates 308 limit the width of the dialysis tubing coil, the electric telescopic rod 404 is activated to extend and retract, thereby driving the pressure plate 402 to move up and down on the surface of the winding roller 401. Adjusting the position of the pressure plate 402 on the surface of the winding roller 401 facilitates the adjustment of the height of the dialysis tubing coil. After the height of the pressure plate 402 is adjusted, the operator manually wraps one end of the dialysis tubing around the surface of the winding roller 401. Then, the motor 406 is started, and the motor 406 drives the winding roller 401 to rotate. Through the limitation of the height of the dialysis tubing coil by the pressure plate 402, and through the limitation of the height and width of the dialysis tubing coil by the four sets of arc-shaped limiting plates 308 and the pressure plate 402, the dialysis tubing is coiled more tightly and neatly, increasing the practicality of this dialysis tubing coiling machine.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
