Embodiment Construction
[0027] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0028] The present invention is a method for measuring bioburden levels of surgical drapes, surgical gowns and clean clothes, comprising the following steps:
[0029] Step 1, sampling and culturing of microorganisms: the 1dm 2 After soaking the sterile absorbent film in sterile saline, stick the sterile absorbent film on the front and back surfaces of the same part of the surgical drapes, the same part of the surgical gown, and the same part of the clean clothes in an aseptic operation. The time is 5 minutes; paste three sterile adsorpt...

The invention discloses a method for determining bioburden levels of a surgical drape, a surgical gown and a cleanroom suit and belongs to the technical field of microbiological determination of medical articles. The method comprises the technical steps as follows: microorganisms on products are collected with sterile adsorption films, culture counting is performed on samples, and the total quantity of microorganisms on the samples is obtained; sterilized sterile sample films are inoculated with a certain quantity of aerobic spores in a product inoculation manner, the aerobic spores are cultured, and correction factors are obtained; the total quantity of microorganisms on the samples is corrected with the correction factors, and thus, the bioburden levels of the samples can be determined.The products are sampled, the bioburdens are determined in a comparative correction manner, so that accurate test results can be obtained, and the method is higher in practicability and suitable for popularization.
Description
technical field [0001] The invention belongs to the technical field of microbial determination of medical articles, in particular to a method for measuring the bioburden level of surgical drapes, surgical gowns and clean clothes. Background technique [0002] The so-called bioburden refers to the total number of living microorganisms on the product. In surgical drapes, surgical gowns and clean clothes, bioburden is also called "cleanliness-microorganisms", which reflects the microbial contamination of surgical drapes, surgical gowns and clean clothes to be sterilized, and the determination of bioburden It can be used as one of the monitoring methods for the comprehensive ability of purification facilities, human flow and logistics control systems to keep products clean. At present, there is no specific determination method for surgical drapes, surgical gowns and clean clothes products in the existing bioburden determination methods. Contents of the invention [0003] The...
