Joint Defense and Control Mechanism Comprehensive Development [2022] No. 64

All provinces, autonomous regions, municipalities, and Xinjiang Production and Construction Corps respond to the joint control mechanism of the new crown pneumonia.

In order to further strengthen the quality management of new crown virus nucleic acid sampling, improve the standardization and accuracy of nucleic acid sampling, and provide safe and high -quality nucleic acid sampling services for the people, the relevant requirements are notified as follows:

1. Fully understand the importance of nucleic acid sampling

Nucleic acid sampling is an important part of the detection of new coronary virus nucleic acid. Singing sampling standard operations, personnel training and organizational management are directly related to the accurate and reliable and personal feelings of the test results. Improper nucleic acid sampling management may not only cause the test results to be inaccurate, but also cross -infection between personnel may also have adverse effects on the prevention and control of the epidemic. All localities should attach great importance to the management of nucleic acid sampling, with problems -oriented, take targeted measures, pay close attention to implementation, standardize sampling link management, and continuously improve the quality of nucleic acid sampling.

2. Ensure that sampling personnel meet the qualifications

The qualification management of nucleic acid sampling personnel must be strictly managed. Based on the existing medical staff, private hospitals, retail pharmacies, school medical rooms, and personnel in enterprises and institutions include health -related professional technical and professional qualifications into the sampling staff team. The administrative department organizes standardized training and passed the assessment before engaging in nucleic acid sampling work. The deployment and use of sampling personnel should not be squeezed as much as possible to occupy normal medical resources to ensure the needs of the people for medical treatment.

3. Standardize the training of nucleic acid sampling training

The health administrative departments of various places shall, in accordance with the "New Coronatte Virus Nucleic acid Test Handbook (Trial Second Edition)" and "New Coronal Virus Nucleic acid Sampling Training Plan" (see attachment) in accordance with the "Medical Institutional Coronatte Nuclear Nucleic acid Testing Test Manual (see attachment) Related work. By making training videos, organizing practical training, etc., the sampling personnel are proficient in common collection methods such as oral pharmaceutical swabs, nasopharyngeal wiral wings, etc., correctly wear personal protective supplies, and implement various infection control measures. Do not replace practical training through video training.

Fourth, strengthen the quality control of nucleic acid sampling

All localities should effectively strengthen the quality control of nucleic acid sampling, and ensure that the operation and behavior of sampling personnel in accordance with the principles of "do not train and do not have the job, the training is not qualified and not qualified". At the same time, each nucleic acid detection agency further do a good job of indoor quality control. By analyzing the internal reference data of the detection reagent to monitor whether the sample swab is collected to the cells to reflect and improve the sampling quality. The administrative department of health and health shall organize on -site inspections of nucleic acid samples, discover problems in time, and put forward targeted improvements.

5. Do a good job of tissue management of nucleic acid sampling

All localities should further strengthen the organizational management of nucleic acid sampling points, guide the sampling points to be equipped with sufficient sampling personnel, auxiliary personnel or volunteers, etc., and reasonably arrange sampling personnel to work and rest, provide corresponding logistics services, implement relevant requirements for care and care for medical staff. Provide the masses with high -quality and efficient nucleic acid sampling services.

New Coronal Virus nucleic acid sampling training scheme

In order to guide the training of nucleic acid sampling personnel, standardize the sampling process, ensure sampling quality, prevent possible cross -infection, and formulate this plan.

1. Training organization

The health administrative departments of various places or their commissioned professional institutions are responsible for formulating training courseware and training courses, and organizing nucleic acid sampling assessments. Those who pass the assessment will obtain a sampling training certificate issued by the health administrative department or the professional institution entrusted by it.

2. Training content

The training content mainly includes oral pharmaceuticals, nasopharyngeal swab collection methods, personal protection, and infection control. The training time is at least 1 day, including theoretical training and operation practice training.

(1) Sample samples of oral pharyngeal and nasopharynxes.

1. Oral pharynx swab collection method. The picked personnel adopted a slightly tilted and mouthful posture to expose the pharyngeal tonsils on both sides. The key point of the sample sample of the oropharynx is to cross the tongue root, wipe the throat tonsils on both sides at least 3 times, and then wipe it up and down at least 3 times on the post -pharyngeal wall. After the sampling is completed, put the swab head in the collection tube of the virus -containing preservation liquid. The cutting point is cut off at the mouth of the tube. Sub -rod, tighten the tube cover, put the collection tube on a stable set. After each case is collected, the sampling person should disinfect it by hand.

2. Nasopharynx swab collection method. The sampling person's hand stretched the nostrils, and the bottom of the nose was slowly deepened. Because the nose was curved, not too hard to avoid trauma bleeding. When the top of the wound arrives at the back wall of the nasopharynx cavity, rotate gently for a week (if you encounter a reflex cough, you should stay for a while), then slowly take out the wound head in the tube of the 2 to 3ml virus preservation liquid. Essence

If multi -person mixed mining, you should also pay attention to the standard operation of the mixing wipe. Taking the 10 -in -1 mixed mining as an example, the remaining 9 places are collected in order according to the above collection methods, and the collection of the collection of the collection is placed in the same collection tube. The movement is gently to avoid the generation of gas solution. After collecting 10 pieces in a row, the tube cover is tightened to prevent overflowing. If there are less than 10 in the collection pipe, special labels should be made and recorded.

(2) Personal protection of sampling personnel. Personal protection includes correcting personal protection equipment (including: medical protective masks, latex gloves, protective surface screens or goggles, isolation clothes or protective clothing, work caps), and regulate hand hygiene. Personal protective supplies are wearing sequences, wearing medical protective masks and working caps, wearing isolation clothes or protective clothing, protective surface screens or goggles, and gloves. After wearing a mask, the mask should be tested densely to ensure good confinement. If the mask is polluted or humid, if the gloves and protective clothing are pollution or damaged, they should be replaced in time.

Before taking off your personal protective supplies, you need to hygienic, then remove the protective screen or goggles in turn, remove the isolation clothes or protective clothing, gloves, and take off your hat and medical protective mask. During the picking process, do not contact the internal clothing when the pollution surface is cut. Before and after each step, hand hygiene must be done, and the hand is not exposed to the pollution surface.

(3) Infection control.

1. Settings point settings partition. The sampling point should be selected with empty and ventilated venues. It is divided into a waiting area, collecting area, buffer area, temporary isolation area, and medical waste temporary area to effectively disperse the density of the personnel for inspection. (1) Waiting area. Set the pedestrian channel and set the safe distance to ensure the protection of the waiting personnel. Equipped with weather conditions, cooling, cooling, shading, rain covering facilities. (2) Collection area. According to climate, it is equipped with tents, cold/warm fans, and appropriate tables and chairs. Equipped with disinfection supplies, swabs, and virus collection tubes, and should prepare paper towels, vomiting bags and masks for personnel. If the specimen cannot be transported to the laboratory in time, it is necessary to prepare a 4 ° C refrigerator or a low -temperature preservation box to be temporarily stored. (3) Caps. The space should be relatively closed, and the sampling personnel can replace personal protective supplies. Protective supplies that match the sampling point scale, collect disinfection supplies, swabs and collect tubes, outdoor disinfecting equipment. (4) Temporary isolation area. Used to temporarily isolate suspected patients or high -risk people found during the collection process. (5) Medical waste temporary area. It is used for temporary medical waste and do a good job of collecting, packaging, harmless treatment, and transfer.

2. Do a good job of cleaning and disinfection. When collecting specimens, hand hygiene is strictly executed. One hand disinfection, that is, after completing the collection of the previous personnel, it must be disinfected in order to perform the next collection operation. During the sampling process, you should pay attention to the prevention and control of the infection. Except for the wove, other parts must not be touched by the being collected to prevent cross -infection. After the sampling site work is over, clean and disinfection of medical devices, items, and surfaces should be done. Use water and cleaner to thoroughly clean the environment surface, and use a valid disinfection agent to the surface of the environmental objects, especially the high -frequency contact site for standardized disinfection. The patient's respiratory discharge, excrement, and vomit are standardized.

3. Avoid crowd gathering. The sampling point needs to be established with a clear guideline to ensure uniform flow of personnel and clarify the sampling process and precautions. When the sampling site refined organizational management, while the staff and volunteers maintain the order of work, encourage physical means to strictly implement the requirements of a safe distance interval through physical means.

Third, assessment

The assessment content includes sampling operations, personal protection and sensory theory knowledge. The main assessment of practical operations, when necessary, you can arrange simple theoretical exams. The main coverage of the following content:

1. Whether you can wear a mask correctly to understand the potential risk.

2. Whether you can correctly grasp the process of penetrating and off isolation clothes or protective clothing to understand the degree of potential risks.

3. Whether it can standardize the collection operation of oral pharyngeal and nasal cavity wipes, and the degree of understanding of the test results of irregular operations may affect the test results.

4. Whether you can correctly perform hand hygiene and understand the degree of infection control methods such as environmental ventilation, cleaning and disinfection, medical waste standardization and disposal.
