Description

Technical Field

[0001] The utility model relates to the technical field of dialysis paper winding, in particular to a winding device for medical dialysis paper. Background Art

[0002] Medical dialysis paper plays a key role as the semipermeable membrane in the dialyzer. Using dialysis paper can effectively remove excess water and solutes in the blood, helping patients with renal failure to restore normal physiological functions. Dialysis paper can remove excess waste and water in the body, maintain the patient's water-electrolyte balance, and prevent the occurrence of renal heart disease and other complications.

[0003] At present, the conventional dialysis paper winding device generally consists of a motor and a winding roller. When in use, the reel for winding the dialysis paper is first sleeved on the winding roller. At this time, the friction between the winding roller and the reel is used to fix the reel. After fixation, the motor drives the reel and the reel to rotate, and the dialysis paper winding and collection can be completed. Since the diameter of the reel is fixed, the reel needs to be replaced when installing reels of different sizes, thereby reducing the winding efficiency of the dialysis paper and increasing the labor of the staff.

[0004] Patent document No.: CN217972059U, including a support plate, a motor and a reel, wherein the motor is installed on the left side of the support plate, the reel is rotatably connected to the support plate through a bearing, the left end of the reel is transmission-connected to the motor through a connecting assembly, the interior of the reel is a hollow structure, the right inner wall of the reel is rotatably connected to a rotating shaft through a bearing, the left and right sides of the outer surface of the rotating shaft are respectively provided with left-handed threads and right-handed threads, and the left end of the rotating shaft sequentially penetrates two movable blocks and the left end of the reel; the utility model can be applied to reels of different sizes, and the reel does not need to be replaced, thereby improving the winding efficiency of the dialysis paper;

[0005] Since the above patent utilizes the mutual cooperation of structures such as connecting components, winding shafts, pressure plates and connecting rods to achieve the clamping and fixing of rolls of different diameters, however, the patent does not limit the two sides of the dialysis paper during the winding process, which easily causes the dialysis paper to shift during the winding process, which not only affects the overall neatness of the winding, but also easily causes looseness due to insufficient winding neatness, thereby affecting the overall winding situation.

[0042] The working principle and use process of this utility model:

[0043] In use:

[0044] When in use, first, put the winding reel on the surface of the inner clamping component 25, and then rotate the bidirectional threaded rod 251. As the bidirectional threaded rod 251 rotates, the moving block 252 will be driven to move, thereby driving the connecting rod 253 to rotate. At this time, the arc clamping rod 254 can be driven to move outward. As the four groups of arc clamping rods 254 move outward, reels of different diameters can be clamped and fixed. After clamping, the staff will pass one end of the cut dialysis paper through the upper part of the tensioning roller 42. When passing through, the upper clamping roller 345 will be driven to move downward through the clamping damping rod 343, and the upper clamping roller 345 and the lower clamping roller 346 can be matched with each other. The paper is clamped, and after passing through, one end of the dialysis paper is fixed to the surface of the reel by tape. After fixing, the staff screws the locking screw 444. When the locking screw 444 is loosened, the limit ring 441 can be moved so that the limit ring 441 slides on the surface of the tensioning roller 42. When the limit ring 441 moves to the known position, the locking screw 444 is screwed to fix the limit ring 441. After fixing, the winding motor 22 can be started. When the winding motor 22 rotates, the winding roller 23 and the inner clamping component 25 will be driven to rotate, thereby driving the reel to rotate, and the dialysis paper can be wound.
