Description

Technical Field

[0001] This utility model relates to the technical field of stable water supply devices, specifically a stable water supply device for hemodialysis. Background Technology

[0002] During hemodialysis, a water supply device is required to supply water to the equipment. According to patent application publication number CN119236211A, a stable water supply device for hemodialysis is disclosed, relating to the field of hemodialysis technology. This invention provides a stable water supply device for hemodialysis, including a mounting plate. A water storage tank is fixedly connected to one side of the mounting plate, and a water pump is fixedly connected to the other side of the mounting plate. A connecting water pipe is connected to the water pump, and the same connecting water pipe is connected to the water storage tank. A lower frame is fixedly connected between the two connecting water pipes, and an upper frame is fixedly connected to the top of the lower frame. The water pump operates to guide water into the water storage tank, where the water flows within the cavity formed by the lower and upper frames, filtering impurities through activated carbon cotton. However, existing water supply devices require filtration during operation. Impurities in the water can clog the filter, affecting flow rate and causing unstable water supply. Furthermore, the supply pipe and pump are bolted together, making disassembly difficult and limiting the device's versatility. Therefore, improvements to the existing technology are necessary.
