Research on the application of reverse osmosis concentrated water in medical instrument pretreatment in central sterile supply department
To explore the effect of reverse osmosis concentrated water produced by the reverse osmosis system in the central sterile supply department on the pretreatment of reusable medical instruments.
Methods
2
A prospective controlled study was conducted. A total of 1 998 contaminated instruments were divided into the experimental group (
n
=1 010) and the control group (
n
=988).The experimental group was pretreated with reverse osmosis concentrated water, while the control group was pretreated with traditional alkaline water. The water quality test results of
the two groups were compared. The post-soaking reprocessing rate, the qualified rate of visual inspection under a magnifying lamp with an attached light source, and the qualified rate of adenosine triphosphate (ATP) bioluminescence detection of the two groups were compared.
Results
2
The pH value of the reverse osmosis concentrated water was 7 to 8, the total hardness was 0 to 1 mg/L, indicating soft water quality.There were no statistically significant differences between the two groups in terms of the post-soaking reprocessing rate (13.96%
vs
.13.56%),the visual inspection qualified rate (both 100%),or the ATP detection qualified rate (both 100%)(
P
>
0.05).
Conclusion
2
Reverse osmosis concentrated water achieves an effect equivalent to traditional alkaline water in medical instrument pretreatment.Meanwhile,it features water saving,environmental friendliness and low corrosiveness,and has promising prospects for wide application.
