Original Title: Six Points for Attention for Medical Staff Working in Nucleic Acid Sampling Workstation of Nucleic Acid Sampling Kiosk! Nosocomial infection prevention and control system of nucleic acid sampling point Due to the recent infection due to nucleic acid sampling, the infection prevention and control system of nucleic acid sampling points was formulated according to the nucleic acid testing manual and the actual situation of the hospital. I. Sampling point selection and requirements: Shan Limei I3O2I663O95 1. COVID-19 sampling sites should be safe The principle of being scientific and convenient for the people. Sampling points should be relatively independent spaces with ventilation conditions, corresponding clean areas and contaminated areas, equipped with hand hygiene facilities or hand disinfection devices, and the sampling process should be "one person, one area". The outdoor sampling points shall arrange the sampling space reasonably according to the number of personnel, and set the waiting area according to the risk. Ensure the one-way flow of personnel as far as possible, implement the "1 meter line" spacing requirements, and strictly control the density of personnel. 2. Indoor air is sterilized by air sterilizer or ultraviolet lamp every day. Disinfect for 3 times, 1 hour each time. Wipe and disinfect the tabletop and countertop with 1000 mg/L available chlorine or 75% ethanol for 3 times every day. Disinfect at any time if contaminated. 3. Environmental sample of sampling point Once every 14 days. Expand the full text II. Personnel management 1. Technicians engaged in specimen collection shall be subject to biosafety Be trained and qualified in monitoring technology, be familiar with specimen collection methods, and master the operation process of specimen collection. Sampling shall be carried out in strict accordance with the operation process, and the specimen information shall be recorded as required to ensure that the specimen quality meets the requirements and the specimen and related information can be traced. 2. Wear work clothes during sampling Wear disposable work caps, gloves, isolation gowns or protective suit (assess the risk, depending on whether there are local cases of infection), medical protective masks, protective face screens,KN95 Face Mask, work shoes and waterproof boots. Wear isolation gowns if necessary. If contact with the patient's nasopharyngeal secretions occurs, immediate hand hygiene and replacement of latex gloves should be performed. 3. The waiting crowd should wear masks correctly throughout the journey. Strictly implement the one-meter line. 3. Collection and Transportation of Specimens 1. Collection of specimens Transportation and storage shall be carried out in strict accordance with the "Technical Guidelines for Collection and Detection of COVID-19 Samples" in the Notice on Issuing the Prevention and Control Plan for COVID-19 (Eighth Edition) issued by the Comprehensive Group of the State Council's Joint Prevention and Control Mechanism for COVID-19 Epidemic. 2. Specimen transportation and disinfection management (1) packaging: after a specimen is collected, wiping or spraying the outer surface of a specimen container with 75% ethanol or 1000mg/L chlorine-containing disinfectant for disinfection, then packaging the specimen container in a special specimen self-sealing bag with a biosafety warning mark, sterilizing the outer surface of the self-sealing bag with 75% ethanol or 1000mg/L chlorine-containing disinfectant, and then placing the specimen container in a special airtight transfer box. Disinfect the outer surface of the transfer box with 75% ethanol or 1000 mg/L chlorine-containing disinfectant. (2) Transportation: The equipment shall be transported to the laboratory by a specially-assigned person who has received biosafety training. The transportation personnel shall wear hats, disposable surgical masks, gloves and isolation gowns. During the transportation, the transportation box shall be kept stable to avoid severe shock and turbulence. (3) Receiving: The laboratory receiving personnel shall disinfect the transfer box with 75% ethanol or 1000mg/L chlorine-containing disinfectant before opening it, free shipping disposable coverall ,KN95 Mask with Fast Shipping, and then disinfect the self-sealing bag with 75% ethanol or 1000mg/L chlorine-containing disinfectant. The self-sealing bag shall be opened in the biosafety cabinet, and the specimen shall be taken out. The specimen information shall be checked in detail, and the handover registration shall be made. IV. Hand hygiene, occupational exposure and spill treatment 1. Hand hygiene 。 All personnel participating in the field work at the sampling point shall strengthen hand hygiene, and can use alcohol-containing quick-drying hand disinfectant and hydrogen peroxide hand disinfectant; if there are visible pollutants, hand sanitizer shall be used to wash hands under flowing water, and then disinfect. Specimen collectors should strictly implement the principle of "one person, one collection and one hand elimination" to prevent cross infection. After the job is done, wash your hands under running water using hand sanitizer and then disinfect your hands. 2. Skin Mucosal and respiratory exposure. When the skin is contaminated by pollutants, the pollutants should be removed immediately with running water and soap solution. If the skin is damaged, it should be wiped and disinfected with iodophor or alcohol disinfectant. The mucosa should be washed with a large amount of normal saline or iodophor. 3. Emergency disposal of overflow 。 A small amount of contaminants can be carefully removed with disposable absorbent materials (such as gauze, rags, etc.) Dipped with chlorine-containing disinfectant solution with available chlorine of 5000mg/L-10000 mg/L (or disinfectant wipe/dry towel that can reach a high level of disinfection). After removal, disinfect with chlorine-containing disinfectant solution of 1000mg/L, and then clean. V. Disposal of Medical Waste After the sampling, the sampling personnel shall write the source of waste, the type of medical waste and the date of handover, seal it with a double-layer yellow medical waste bag and a gooseneck knot, make a good identification and handover with the collection personnel, and sign both. Pay attention to sealing when the medical waste reaches 3/4 of the loading capacity. Disinfect with 1000 mg/L chlorine-containing disinfectant solution after handover and transfer, and wipe with clean water after 30 minutes. VI. Disinfection of Environmental Ground 1. Sampling points shall be ventilated as much as possible The air sterilizer can be used to sterilize people three times a day. Ultraviolet rays can be used to disinfect the air in the absence of people. The ultraviolet radiation illumination should be ≥ 70 μW/cm2, and the irradiation time should be more than 1 hour. Record the irradiation time and the cumulative irradiation time. 2. Items on the ground and in the room ? When there is no obvious contamination on the surface of tables and chairs, use disinfectant containing chlorine disinfectant (500-1000 mg/L) to wipe, and wipe with clean water to remove the residual disinfectant. Disinfect three times a day. 3. Ground When the walls or the surfaces of the above objects are obviously contaminated by blood, body fluids, etc. Or splashed by secretions, etc., disinfectant wipe or disposable absorbent materials (such as absorbent paper, gauze, etc.) Should be used in a timely manner to dip disinfectant solution with an effective chlorine content of 10000 mg/L to remove visible liquid pollutants, and then spray or wipe with chlorine-containing disinfectant solution of 1000mg/L.
