It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope.

[0014] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figure 1 As shown, it includes dialysis water treatment equipment and thermal disinfection device and connecting pipelines and control valves. The device is connected to the return pipe 31 and the water inlet pipe 23 of the hemodialysis water treatment equipment through the first ports of the three-way valve Y3 and the three-way valve Y4 respectively. The other ports of the three-way valve Y3 and the three-way valve Y4 are connected to the water point pipeline of the water permeator. The third ports of the three-way valve Y3 and the three-way valve Y4 are connected to the thermal disinfection device.

[0016] The water inlet pipe is equipped with an inlet valve Y1. The thermal disinfection device mainly consists of a water tank 30, a thermal disinfection pipeline, and a circulation pump M1. The thermal disinfection pipeline is equipped with a circulation valve Y2 and a discharge valve Y5. A one-way valve Y6 is installed between the water inlet pipe and the thermal disinfection pipeline. The water tank is equipped with a spray ball 25, a heating rod 29, an ultraviolet disinfection lamp 28, and a temperature sensor TT0. The water tank is also equipped with a liquid level sensor PTO and a double float liquid level sensor PT1. A respirator 26 is installed on the top of the water tank. The thermal disinfection pipeline is also equipped with a sampling valve PH1 and a pressure regulating valve PI. Two bacterial filters 24 are installed on the thermal disinfection pipeline. A temperature sensor TT1 is installed on the thermal disinfection pipeline outside the water tank. Several water points 22 are set on the water point pipeline of the water permeator as needed. The heating rod 29 is a flow-through resistance heating rod or an electromagnetic induction heating rod.

[0017] The online thermal disinfection device of the present application is linked to the dialysis water treatment equipment and installed at the end of the pure water pipeline, which does not affect the normal dialysis water use. When the water treatment equipment produces water and supplies water to the water point, the Y3 and Y4 three-way valves are in positions 1 and 2. During pipeline thermal disinfection and online thermal disinfection, the three-way valves are in positions 2 and 3. The stainless steel sterile water tank is equipped with a liquid level sensor PT0, a double float liquid level sensor, a temperature sensor TT0, a temperature sensor TT1, a heating rod, an ultraviolet disinfection lamp, a respirator, and a spray ball. The double float liquid level sensor serves as a high liquid level protection to prevent the liquid level sensor PT0 from failing and the water inlet valve Y1 from continuously inletting water.

[0018] Online thermal disinfection of the dialysis machine: The water treatment equipment produces water, the Y1 inlet valve opens, and after the water tank is filled to the high level, Y1 closes. The Y2 circulation valve opens, the heater starts, and the circulation pump M1 initiates circulation heating. When both temperature sensors TT1 and TT0 register 85°C, the heater stops heating. The Y2 circulation valve closes, and the three-way valve switches to positions 2 and 3, continuously supplying 85°C hot water to the dialysis machine. This improves the disinfection efficiency of the dialysis machine and eliminates a dead end in the dialysis machine inlet hose of the water treatment equipment. After thermal disinfection is complete, the three-way valve switches to positions 1 and 2, and the water treatment equipment produces water.

[0019] Thermal disinfection of the pure water pipeline in the ward: The water treatment equipment produces water, the Y1 water inlet valve opens, and after the water tank is filled to the middle liquid level, Y1 closes. The Y2 circulation valve opens, the heating rod 29 starts, and the circulation pump M1 starts circulating preheating. When the temperature sensors TT1 and TT0 both show 50°C, the preheating ends, the Y2 circulation valve closes, the three-way valve position changes to positions 2 and 3, and the circulation pump M1 circulates and heats the water in the pipeline. When the temperature sensor TT1 reaches 85°C, the timer starts and the temperature is kept at 85°C. After 20 minutes, the disinfection ends, the discharge valve Y5 opens, and the hot water in the pipeline is discharged. The three-way valve position changes to position 12, the water treatment equipment produces water, and the water inlet valve Y1 opens to let water in.

[0020] The centralized liquid supply system for dialysis concentrate is provided with normal temperature water: when the water treatment equipment produces water, the Y1 water inlet valve is opened, and after the water tank is filled to the highest liquid level, Y1 is closed. The Y2 circulation valve is opened, the heating rod is started, and the circulation pump M1 starts the circulation heating. When the temperature sensors TT1 and TT0 both show 35°C, the heating rod stops and the circulation pump stops. When the temperature is lower than 25°C, the heating rod starts and the circulation pump starts to ensure that the water temperature in the water tank is between 25-35°C. When the centralized liquid supply system needs to be dosed, open the centralized liquid supply water inlet valve Y7 to continuously provide warm water for the centralized liquid supply system to improve the disinfection and quality of the dispensed liquid.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
