[0002] 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 the electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance.

[0003] The amount of water that hemodialysis patients drink needs to be strictly controlled. When patients drink water, they need to use a measuring cup to accurately control it, which is a cumbersome operation. Therefore, this application proposes a water control cup for hemodialysis patients to solve the above problem. Utility Model Content

[0021] A water intake ring 11 is fixedly connected to the outer wall of the limiting tube 6, and an external tube 12 is fixedly connected to the lower end of the water intake ring 11. The external tube 12 is sleeved on the limiting tube 6, and a clamping protrusion 13 is arranged at the lower end of the outer wall of the external tube 12. The outer diameter of the external tube 12 is smaller than the inner diameter of the through hole 16, and the length of the external tube 12 is greater than the thickness of the partition 17. The clamping protrusion 13 is made of rubber material. When the device is not in use, the water intake ring 11 is pressed downward to drive the limiting tube 6, the external tube 12 and the clamping protrusion 13 to move downward. When the clamping protrusion 13 is below the partition 17, the clamping protrusion 13 cooperates with the partition 17 to realize the position limitation of the limiting tube 6 and the water intake tank 4.

[0022] The lower end of the partition 17 is fixedly connected with a sealing frame 10, and the limiting tube 6 passes through the lower side wall of the sealing frame 10 and is slidably connected with the lower side wall of the limiting tube 6. The sealing frame 10 is made of rubber material, and the thickness of the lower side wall of the sealing frame 10 is greater than the diameter of the water intake hole 8.

When the patient drinks water, the cup cover 3 is opened, the clamping protrusion 13 is pulled out by pulling the water intake ring 11 upwards, and the water intake tank 4 is lifted up by the limiting tube 6. When the water intake hole 8 exceeds the liquid level, the excess water in the limiting tube 6 flows out from the water intake hole 8. The limiting tube 6 is pulled upwards continuously. When the upper end of the water intake tank 4 abuts against the lower end of the sealing frame 10, the seal is The lower side wall of the frame 10 blocks the water intake hole 8, and the patient can then suck the water in the water intake tank 4 into the inlet through the water suction pipe 9. The device does not require the patient to measure, and only needs to replace the water intake tank 4 of different capacities according to the patient's water drinking needs, which is more convenient to use; at the same time, the large-capacity water storage cup 1 can store more water, which is convenient for the patient to carry and use water at any time; the water storage cup 1, cup cover 3, connecting pipe 2, water intake tank 4, limiting pipe 6 and water suction pipe 9 in the device are all detachable for easy cleaning.
