Feasibility Study Report on Centralized Liquid Supply System

Dilute concentrated A powder or B powder according to the dilution ratio of the concentrated solution formula and prepare it with reverse osmosis water; The pre configured concentrated solution is directly transported to each hemodialysis machine through pipelines. This method is currently a good way to improve the purity of dialysate in China and has many advantages over single machine and single barrel systems 

1、 Safety: 

1. High purity (with 0.45 μ m and 0.1 μ m filters installed in the centralized liquid supply system), can make the dialysate reach ultra pure dialysate (endotoxin<0.1EU/ml), with better dialysis effect, and can also meet the industry standard for dialysis concentrate in 2017 (yy0598-2015, endotoxin<0.5EU/ml);

2. The negative area and positive area should be supplied separately to prevent cross infection;

3. Implement daily use and preparation to ensure fresh and stable dialysate;

4. Real time online monitoring of liquid concentration to maintain the stability of the concentrated solution;

5. The system automatically performs thermal disinfection every day, and the dialysate storage tank is pharmaceutical grade fully sealed. The dialysate circulates in the pipeline, which can prevent bacterial growth and reduce endotoxins (endotoxins<0.1EU/ml);

6. The existing dialysate tank is open, and the dialysate is in a static state inside the tank, which can easily cause secondary pollution caused by blood stains, saline, and debris entering the tank. The centralized liquid supply system will completely eliminate such pollution.

2、 Environmental Protection:

1. There are domestic manufacturers producing AB concentrated dialysis solution due to high costs, transportation expenses (about 15 yuan per person per time), and packaging expenses (about 15 yuan per barrel). Centralized supply of solution can effectively save such resources;

2. More convenient for medical staff work: Dialysis fluid tanks need to be replaced frequently during patient dialysis, which often conflicts with the work of medical staff and affects their work. Centralized supply of fluid will completely eliminate the secondary pollution and storage problems of dialysis fluid tanks.

3、 Management:

1. High degree of automation, the entire system adopts programmable logic controller (PLC) for automatic control, without the need for manual intervention;

2. Adopting human-machine dialogue LCD touch screen and high-precision liquid level sensor control can ensure highly accurate liquid concentration and ensure the adequacy of dialysis for patients;

3. The personnel and formula can be set separately according to the actual usage situation;

4. It has functions such as automatic liquid dispensing, automatic cleaning, automatic discharge, automatic thermal disinfection, and timed circulation. All parameters only need to be set, and it is a one click operation without the need for manual switching of valves, truly achieving fully automated control;

5. The system realizes automatic liquid dispensing and supply, freeing nurses from physical labor and allowing them to devote more energy to nursing work;

6. Can connect to a data management system for convenient collection and analysis of dialysis data;

4、 Cleanliness:

1. Save space resources in the dialysis center. The stacking of dialysis concentrate is now an important part of the dialysis room, and the centralized liquid supply system solves the problems of finished product stacking and waste bin stacking in the dialysis room;

2. Make the environment of the dialysis room cleaner and more beautiful: Currently, the single machine poke type liquid supply has at least four buckets (A solution, B solution, disinfectant, acid pickling solution) in front of each dialysis machine, which not only affects the work of nurses but also affects the cleanliness and beauty of the dialysis room.

5、 Cost savings:

The current price of dialysate is 75 yuan per person per session

The annual cost of purchasing dialysate is75*30000=2250000元

After centralized liquid supply system, per person 60元*30000=1800000元

Annual savings in pure procurement costs：450000元。

The effective development of the department and other resource savings are not considered.

Conclusion:

Centralized fluid supply in large dialysis centers is the future development trend, which can effectively improve the quality and efficiency of departmental work. A good centralized liquid supply will achieve true ultra pure dialysis, benefiting patients, ensuring medical safety, improving efficacy, saving costs, maintaining cleanliness and tidiness. It represents the direction of industry development and is conducive to the overall development and external influence of the hospital.
