2) Mixing pump -- 316L stainless steel impeller pump; 3) Circulating pump -- using anti-corrosion acid and alkali magnetic pump /316L stainless steel centrifugal pump; 4) Electric ball valve assembly -- using anti-corrosion acid and alkali resistance electric ball valve; 5) Filter component: 1μm filter element, 0.22μm and 0.1μm microporous filter element;




6) The liquid supply pipeline is made of corrosion-resistant sanitary grade 304/316L stainless steel pipe.
Hemodialysis centralized fluid supply system (thermal disinfection) Standard functions:


1) Automatic liquid mixing function: The system can simultaneously configure A and B concentrated liquid (automatic water intake, mixing, transportation).

2) Automatic conveying function: The system simultaneously transmits A, B and concentrated liquid to the dialysis unit.

3) Cleaning function of the dispenser: automatically clean the dispenser tank and related pipelines after each dispensing.

4) Liquid supply system disinfection function: can automatically complete the liquid supply system disinfection and flushing.

5) A variety of liquid dispensing options: the corresponding amount of liquid dispensing can be selected according to the actual number of open dialysis machine.

6) Pulse circulation function of the liquid supply pipeline: it can cycle the liquid storage pipeline A and B at night to avoid crystallization inside the pipeline.

7) Automatic operation monitoring system: Chinese touch man-machine interface, with a variety of alarm functions.

8) Remote monitoring function is optional: monitoring device is installed in the nurse station to know the running status of the equipment in real time.

9) Real one-button chemical disinfection and thermal disinfection function, heater and heating medium do not contact, electric valve operation, no manual valve switch, after the completion of chemical disinfection prompts to detect peracetic acid residue.

10) Self-diagnosis and alarm function: the system should have sound and light alarm function, Chinese prompt fault cause, alarm status and other information, convenient diagnosis, but also should have perfect pressure, flow, power and conductance exceeding the alarm function.

11) Control system: PLC+ touch screen combination, Chinese menu operation, password protection function, extensible IT connection and remote monitoring.

Four, hemodialysis centralized liquid supply system (thermal disinfection) product characteristics

1) All parts in contact with liquid are made of medical stainless steel (304, 316L)

Poison, no corrosion, no pollution, long service life.

2) According to clinical requirements to provide a variety of model formula selection, at the same time according to the actual dosage can be set up

Number of copies.

3) Multistage precise filtration (1µm, 0.2µm, 0.1μm) can completely avoid the contamination of bacteria and endotoxin to the dialysate, and prepare the real ultra-pure dialysate.

4) Liquid storage tanks for liquid A and B are fully sealed containers equipped with high-precision breathing apparatus.

5) In the preparation process, the concentration of dialysis concentrate is monitored in real time and automatically supplied to the liquid storage tank after reaching the standard.

6) Automatically clean after each liquid distribution, and automatically drain the cleaned water.

7) It has storage capacity display of liquid A and liquid B and alarm warning that dialysate is about to run out.

8) After disinfection, the liquid dispensing bucket, liquid storage bucket and liquid supply pipeline will be cleaned automatically. The cleaning times can be set.

9) The dialysate (B liquid) in the storage tank and supply line can be automatically emptied after the completion of dialysis, and the dialysate concentration can be automatically calibrated when the dialysate is reformulated.

10) Password protection function to ensure special operation, improve the safety of liquid supply.

11) Two options are available: automatic and manual. When manual, liquid can be dispensed manually according to tank level scale, which will not affect the safe use of dialysis liquid.

12) Equipped with heating controller to ensure the complete dissolution of dialysis powder when the water temperature is low in winter, and can carry out hot disinfection of tank and pipe above 85℃.
