Description
The technical field is as follows:
the utility model relates to a medical supplies technical field relates to an scope detects sampling bottle.
Technical background:
the method for detecting endoscope after disinfection described in the hospital disinfection and health standard (GB 15982-2012) is a membrane filtration method: taking the cleaned and sterilized endoscope, extracting 50mL of eluent containing corresponding neutralizer by using a sterile syringe, injecting the eluent from a biopsy port to wash the lumen of the endoscope, and collecting the whole amount (a peristaltic pump can be used) for inspection. Mixing the eluate, inoculating 1.0mL of the eluate into plates, cooling the molten nutrient agar to 40-45 deg.C, pouring 15-20 mL of agar into each plate, shaking, cooling, solidifying, culturing in 36 + -1 deg.C incubator for 48h, calculating colony count (CFU/piece), filtering the rest eluate with filter membrane (0.45 μm) under aseptic condition, inoculating the filter membrane onto nutrient agar plate, culturing at 36 + -1 deg.C incubator for 48h, and counting colony count.
When the filtration process is not countable: total number of colonies (CFU/piece) ═ m (CFU/plate) × 50
In the formula: m is the average colony number of two parallel plates.
When the filtration membrane process can count: total number of colonies (CFU/piece) ═ m (CFU/plate) + mf (CFU/filter)
Wherein: m is the average colony number of two parallel plates; mf is the number of colonies on the filter.
The collection bottle for domestic detection is common in three types, the first type is that the tip of an endoscope is connected with a tube (increasing the probability of pollution) during sampling, eluent flowing out of the lumen of the endoscope is collected into the bottle through a peristaltic pump and is taken back to a laboratory for treatment, the middle of a connecting tube is unscrewed during laboratory inoculation, and a 1mL syringe is used for sucking liquid at the unscrewing part of the connecting tube for inoculation after disinfection, but the sucking of 1mL is difficult, and the sucking amount is difficult to control accurately; and the second method comprises the following steps: directly pouring the sampled liquid into a cup, and pumping the liquid by using a vacuum pump, and has the defect that the sampled liquid is exposed in the air, so that the pollution is increased; the third one is similar to the first one, but has the disadvantage that the cap on the bottle is opened directly to pour the sample liquid, and the cap is easy to fall off to cause pollution.
