METHOD FOR EVALUATING EFFICIENCY OF ENDOSCOPE ASEPTIC STORAGE DEVICE Russian patent published in 2020 - IPC A61L2/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to sterilization of medical products, and can be used for checking the efficiency of sterilization of medical equipment used for aseptic storage of endoscopes, in order to prevent the risk of repeated contamination. Disclosed is a method of evaluating the effectiveness of endoscope aseptic storage device, in which a device with sterile endoscopes, as well as a sterile control endoscope is placed in a test chamber, measuring the air content in the test chamber, daily during the intended storage life of endoscopes, spraying in the test chamber a suspension of test microorganisms in an amount, sufficient to create test-microorganisms concentration in chamber of 2.0 × 10⁵–2.2 × 10⁵ CFU/m³, after end of test session from endoscopes arranged in endoscope aseptic storage device, and the control endoscope, washing off the biopsy channel, endoscope insertion part surface, handle and valve seats of the water/air supply channel, as well as an aspiration channel, contamination levels are measured in the selected washings, contamination levels are compared in the selected washings before spraying the suspension of test microorganisms in the test chamber and after the test session and based on the comparative analysis, the presence of aseptic storage conditions of endoscopes in the aseptic storage of endoscopes is determined with observing the condition of no increase in contamination levels in the selected washings from endoscopes placed in the test chamber, with increase of contamination levels in the selected washings from the control endoscope.

EFFECT: invention provides a reliable assessment of the efficiency of the endoscope aseptic storage device.
