The principle that pathogenic testing should abide by is: it is very important to avoid personal infection and sample contamination during sampling. The collected samples should be regarded as infectious, and necessary protective measures should be taken, safe operation should be paid attention to, and they should be packaged and transported safely. A first aid kit should be available to ensure safety in case of accidental leakage during sampling.
Technical personnel engaged in collecting samples for detection of highly pathogenic pathogens must undergo biosafety training and possess corresponding experimental skills. During the sample collection process, sampling personnel should carry out safety protection (including vaccination, etc.) in accordance with the protective measures prescribed by the relevant national regulations.
Wear overalls, gloves, masks and hats when taking samples; gloves cannot be reused when contacting different patients to avoid cross-infection; cuts should be avoided when using or handling syringes, scalpels and other sharp instruments. Injuries and damage to gloves may occur; wear protective clothing as much as possible during sampling, and choose different protective clothing based on the estimated epidemic level.
Disinfection personnel must wear protective clothing and thick rubber gloves when disinfecting surfaces and spills in contaminated areas; to avoid inhaling highly contagious pathogens, they also need to use respiratory protective masks, goggles, etc. Protective equipment.
Medical (experimental) waste generated during sample collection and processing should be placed in leak-proof special packaging (bags); discarded needles, glass test tubes, ampoules and other sharp objects must be placed in compliance with the requirements in the sharps box and destroy them in accordance with regulations; contaminated disposable equipment and materials should be disinfected first and then discarded; contaminated reusable equipment or materials should be disinfected first and then cleaned; packaging containers (bags) containing waste must be in a protective Leakage and spill-proof turnover boxes are transported safely.
One sample per container. The container must be leak-proof and preferably made of durable plastic materials that comply with national regulations and can withstand temperature and pressure changes that may occur during transportation. All sampling utensils and containers must be strictly sterilized, and samples must be collected using aseptic operations to strictly avoid any damage caused by sampling to inspection products. New pollution.
During the transportation of samples, it is required to adopt a "Class A" or "Class B" three-layer packaging system, which consists of the main container (sample holding container) and the auxiliary container (or auxiliary container) from the inside to the outside. Grade 3 containers) and outer packaging (or Grade 3 containers). Class 2 containers such as boxes should be used for sample transfer within the facility (within the unit).
Unexpected incidents or accidents during sample collection and processing should be properly handled and reported promptly in accordance with the time limits and procedures prescribed by the state and/or local government. If necessary, effective measures should be taken to prevent and control infection. When highly pathogenic microbial strains (viruses) or samples are stolen, robbed, lost or leaked during transportation or storage, the parties or discoverers shall take necessary control measures and report to relevant units within 2 hours. and reports from its competent authorities.
