Description

Technical Field

[0001] This utility model relates to the field of hemodialysis conversion technology, specifically to a hemodialysis conversion device. Background Technology

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. Through diffusion and convection, substances are exchanged, achieving hemodialysis conversion. This helps to remove metabolic waste products from the body and maintain electrolyte and acid-base balance. It represents a significant breakthrough in the medical field. Hemodialysis is generally performed by purifying blood using a dialyzer.

[0003] For example, Chinese patent application No. 202022341338.7 discloses a hemodialysis conversion device for clinical use in nephrology, including a base and a dialyzer body. An electric push rod is bolted to the surface of the base, and the top of the electric push rod is fixedly connected to the outer shell body. A top plate is movably connected inside the outer shell body, and several first tightening springs are connected to the bottom of the top plate. The bottom of the first tightening springs is fixedly connected to the inside of the outer shell body. The dialyzer body is placed on the surface of the top plate. The electric push rod installed on the base facilitates height adjustment of the dialyzer body. A buffer pad, dialyzer body, top plate, and first tightening springs are installed inside the outer shell body to protect the dialyzer body. A tube guide plate, roller, second tightening spring, slide rod, sliding block, and fixing block are installed on the surface of the outer shell body to prevent the infusion tube from getting tangled and affecting use.

[0004] However, the following problems still exist in this technical solution: the dialysate reservoir is required during dialysis, but it is simply placed randomly on the dialysis machine, which makes it easy for it to slip and tip over, which is not conducive to safe dialysis for patients.

[0010] Preferably, the connecting plate is provided with a rack, and the two sides inside the control box are movably connected to a rotating shaft through bearings. Each rotating shaft is fixedly provided with a gear on its outside. The gear meshes with the rack. The ends of the two rotating shafts that are far apart pass through the control box and extend out of the two sides of the control box respectively. A first motor is fixedly provided at one end of the rotating shaft for driving the plug-in plate to move.

[0011] Preferably, handles are fixed on both sides of the top of the base plate for moving the present invention.

[0012] Preferably, a support plate is fixedly provided on the top of the base plate to support the hemodialysis machine.
