Safety measures and quality assurance of clinical microbiology laboratory
(1) Source of laboratory infection
1. Dangerous microbial aerosols may be produced in all aspects of the inspection process.
2. Contact with infectious materials or make them attached to clothes to bring them out of the room, and other accidents such as bacteria dripping on the surface of objects, accidentally piercing the skin during injection, etc. For the above sources of infection, if proper protection or timely treatment is not carried out, it is easy to cause laboratory infection. Therefore, clinical microbiologists should pay attention to personal protection. They must wear work clothes, masks, and hats during the test, and wear protective glasses and rubber gloves as needed. Change clothes and wash hands when leaving. Laboratory tables should be treated with disinfectant immediately after work is completed or when they are contaminated by infected materials.
(2) Disposal of infectious waste
1. Any contaminated materials cannot be taken out of the laboratory without disinfection.
2. Liquid waste must be collected in leak-proof, unbroken containers, and treated with high-concentration chemical disinfectants.
3. The remaining specimens, inoculated culture medium, and bacterial strains must be properly disinfected before discarding.
4. The waste in the animal room needs to be disinfected before disposal and before the animal cage is cleaned. It is best to be autoclaved.
5. Do not touch any contaminated sharp objects such as needles, syringes, glass slides, etc. before handling.
(3) Indoor quality control of microbiology laboratory
The indoor quality control of the microbiology laboratory includes:
1. Requirements for bacteria inspectors;
2. Operation manual;
3. Function monitoring of equipment;
4. Quality control of culture medium;
5. Quality control of reagents, staining solutions and antibiotics;
6. Quality control of specimen inspection;
7. The source and preservation of standard strains and comprehensive control of indoor quality.
