Original Title: New Rules for Wearing Medical Masks! The third edition of "Guidelines for the Prevention and Control of Novel Coronavirus" is coming Compared with the previous edition of the guide, what are the differences in the third edition and what are the main adjustments? On September 13, 2021, the National Health Commission issued the Technical Guidelines for the Prevention and Control of New coronavirus Infection in Medical Institutions (the third edition) (hereinafter referred to as the "Guidelines"), only five months after the publication of the second edition. The first edition of the guide was released on January 23, 2020. Compared with the previous edition, the new edition of the guidelines mainly increased the contents of "medical staff protection" and "closed-loop management of fever clinics and designated hospitals". The content structure has not been greatly adjusted, which is divided into four chapters: "overall requirements", "prevention and control strategies", "basic requirements" and "technical requirements of key departments and departments". Since this year, there have been many hospital infection incidents, requiring hospitals to refine the sensory control program. Since this year, hospital infection incidents have occurred in many places, which has sounded the alarm bell for hospital infection control. On January 19, the official website of the National Health Commission issued a circular on the inadequate prevention and control of COVID-19 in Gaocheng People's Hospital of Shijiazhuang City and Xinle Hospital of Traditional Chinese Medicine in Hebei Province, which included 14 positive cases, including a 70-year-old hospital nurse who was diagnosed. Problems such as confusion in hospital management, failure of health departments and local prevention and control command departments to perform their duties have been exposed, and Hebei Province and Shijiazhuang City have held relevant personnel accountable. At the end of July, a large-scale hospital infection broke out in the Sixth People's Hospital of Zhengzhou, and nearly 150 hospital staff and patients were infected. As a former "anti-epidemic star" of Henan Infectious Disease Hospital, Ma Shuhuan, Secretary of the Party Committee of the hospital,KN95 Mask with Fast Shipping, was dismissed after the hospital infection occurred. The Sixth Hospital of Zhengzhou is still in the period of recovery and reconstruction, and has not yet been opened.

Yesterday, the First Affiliated Hospital of Xiamen University announced that the nucleic acid test results of a logistics service staff of a third-party company in the hospital were positive. These incidents are reminding medical institutions to guard against weak links in the work of sensory control. Especially after the occurrence of large-scale nosocomial infection in Zhengzhou Sixth Hospital, the Joint Prevention and Control Group of the State Council issued three documents on strengthening the sensory control of designated hospitals, improving the sensory control mechanism of medical institutions, and strengthening the management of sensory control personnel in medical institutions within a month, which provided more norms for hospital sensory control work. The contents of these documents are also reflected in the guidelines released this time. The guidelines require strict implementation of the requirements of the above documents,free shipping disposable coverall, including equipping a team of highly professional infection control personnel according to the requirements; medical institutions should formulate detailed training programs for all staff of infection prevention and control in their institutions, and further strengthen the awareness that "everyone is a practitioner of infection control". To strengthen protection, some medical staff masks should be tested for tightness. "Proper Use of Personal Protective Equipment" is part of the "Essential Requirements" section of the guide. The content of the old guide is: Medical institutions should strengthen the management of personnel protection and reserve protective materials of good quality and sufficient quantity. Medical staff should correctly and rationally use medical surgical or medical protective masks, goggles or protective screens, gloves, isolation clothes or protective suit according to exposure risks and diagnostic and therapeutic operations, so as to ensure that personal protection of medical staff is in place. At the same time, they should guide and supervise patients and their accompanying personnel, as well as other personnel entering medical institutions to do a good job of personal protection. The latest edition of the guidelines adds a paragraph to the above content, requiring some medical staff masks to be tested for tightness: In isolation wards, fever clinics, nucleic acid sampling points, nucleic acid testing laboratories and other key places, medical staff who are more likely to come into contact with the novel coronavirus should strengthen protection and strictly implement the requirements of wearing medical protective masks. The personnel working in the fever clinic and the isolation ward of the designated hospital shall be tested for the suitability and tightness of the medical protective mask, and only those who are qualified shall be allowed to work; before entering the fever clinic and the isolation ward of the designated hospital, the tightness of the medical protective mask shall be tested. What should I do if the mask falls off carelessly in the polluted area? Guidelines require posting of disposal procedures For the contaminated areas of designated hospitals and wards for COVID-19 treatment, Virus Prevention Mask 3 Ply with Earloop ,Full Body Disposable Coverall, the old version of the guidelines requires that "the contaminated areas should be equipped with individually packaged personal protective equipment and occupational exposure emergency disposal boxes for emergency use", while the new version of the guidelines also requires that "the disposal procedures after respiratory occupational exposure (see Annex 4) should be posted in obvious places". Annex 4 reads as follows: Disposal process after respiratory tract occupational exposure 1. Respiratory exposure Close contact with patients diagnosed with COVID-19 due to lack of respiratory protective measures, damage to respiratory protective measures (such as loose masks, falling off, etc.), use of ineffective respiratory protective measures (such as use of masks that do not meet the requirements of the specification); contact with mouth and nose by hands contaminated by COVID-19, etc. II. Disposal Process (1) When occupational exposure to respiratory tract occurs in a medical staff, measures shall be taken immediately to protect the respiratory tract (covering the mask with the hand after the implementation of standardized hand hygiene or adding a layer of mask urgently, etc.), and the contaminated area shall be evacuated according to the prescribed procedures. (II) Pass through the unloading area in an emergency, and unload the protective equipment according to the requirements of the specifications. (3) Clean and disinfect the oral cavity or/and nasal cavity with clean water, 0.1% hydrogen peroxide solution and iodophor according to the situation, and leave after wearing a medical surgical mask. (4) Timely report to the director of the department concerned, the head nurse and the competent department of the medical institution. (5) Medical institutions shall organize experts to conduct risk assessment as soon as possible, including confirming whether isolation medical observation, preventive medication and psychological counseling are needed. (VI) Persons with high risk exposure shall be managed as close contact persons, and shall be isolated for medical observation for 14 days. (7) Fill in the occupational exposure record form of COVID-19 medical staff in time, especially the causes of exposure, and carefully summarize and analyze them to prevent similar incidents. Some fever clinics also need closed-loop management. The technical requirements for key departments and departments in the guidelines are independent. These key departments and departments are: fever clinics, emergency departments, departments/departments where patients need to remove masks when receiving diagnosis and treatment measures, hemodialysis centers (rooms), general wards (rooms), designated hospitals and wards for the treatment of COVID-19 infected persons, and COVID-19 nucleic acid testing laboratories. Among them, the new guidelines have greatly increased the contents of the two sections of "fever clinics" and "designated hospitals and wards for the treatment of novel coronavirus infected persons". For fever clinics, the new guidelines put forward more specific requirements for protection: medical staff entering and leaving fever clinics and observation wards should wear medical protective masks, work caps, gloves, boots or shoe covers (protective suit do not need to wear boots if they already have boots), wear isolation gowns or protective suit (observation wards should wear protective suit), and wear goggles or protective screens according to the operation of diagnosis and treatment. And part of the fever clinic staff to strict closed-loop management, this part is: reception entry, domestic high risk areas and focus on the isolation point of fever patients and other high-risk groups of fever clinics. All personnel in the isolation ward travel at two points and one line. In the old version of the guidelines, the isolation wards of designated hospitals were required to carry out closed-loop management, while the new version of the guidelines put forward one more point: "strict implementation". Specifically, during the working period, a single person will be arranged to live in a single room, and all personnel will travel between the station and the designated hospital at two points and one line, with fixed commuting vehicles, and no station will be arranged in the designated hospital. The new guidelines also specify the scope of "all staff" in the isolation wards of designated hospitals. Including: medical, management, security, cleaning, catering, medical waste collection and transportation personnel and other staff who directly or indirectly contact with COVID-19 infected persons (including medical staff such as imaging examination and closed-loop management personnel who provide services for COVID-19 infected persons). In addition, for designated hospitals, the new guidelines also have several provisions that the old version did not have: in principle, the reserve should meet the needs of designated hospitals to operate at full capacity for 30 days; fever clinics should immediately transfer new coronavirus infected persons to designated hospitals; For the management of accompanying and visiting, the expression of "in principle" has been deleted from the old version of "no arrangement for visiting and accompanying in principle", that is,KN95 Face Mask, "no arrangement for visiting and accompanying".
