While the current infusion and the infusion have been terminally sterilized, but in some medical conditions are relatively poor environment, pharmaceuticals and connections
Infusion equipment will still process microorganisms in the environment may be introduced into the infusion system. Some infusion fluid (such as certain nutrient solution) itself has
Contribute to the growth of microorganisms. Thus, the liquid sterilizing grade filters have considerable market demand. The method given in this standard can be used to determine the sterilizing grade
Liquid filtration membrane filter in the liquid retention capacity of bacteria.
Currently accepted in the liquid membrane to filter out bacteria in the maximum pore size is 0.22μm. Typically, this test is only through the liquid filtration
Film before the membrane pore size is nominally 0.22μm.
Limitations of bacterial retention test in that it can not filter membrane liquid filter production process control routine. Conventional control
Generally use the bubble point pressure test test filtration membrane filter pore size and integrity (see YY/T 0929.1), the bubble point pressure indicators subject to this standard

War, so that the final challenge level is not less than 107CFU/cm2EFA. All filtrates were then analyzed after membrane filtration, the analysis filter means
Cultured in solid medium. You will be able to form a visible colony tried through the membrane or filter for bacteria on the analysis membrane, and into the
The row count.
NOTE. When you need to assess whether the filter or filter membrane to maintain its long-term use of bacterial retention capacity, we can use the test program is given in Appendix A.
5. Significance and Use
5.1 Test methods designed to evaluate the sterilizing grade filter membrane or filter bacteria retention capacity under clinical conditions.
5.2 per square centimeter of the effective filtration area is subjected to 107 bacterial challenge levels much higher than the sterile filtration process. The selection of challenges
It is to provide high level of security for the filter membrane filter or intercept a large amount of microorganisms.
