Isolation Gown Standard interpretation of
"The epidemic came suddenly, and all kinds of protective equipment were very tight! 'Protective clothing is for you, but I can only wear isolation clothing!'" This is a report from Dahe Net, which mentioned that in order to save protective materials and ensure that every medical staff in the fever clinic can wear protective clothing every day, the head nurse Xu Weina never wore protective clothing when entering the fever clinic, They are all a isolation suit, a mask and a round hat. This article Medical isolation suit Relevant standards are interpreted, and isolation clothing and protective clothing are briefly compared.
1. What is the medical isolation suit
At present, there is no standard or industry standard for medical isolation clothing. The American standard ASTM F3352-19 [1] defines medical isolation clothing as protective clothing (clothing) used to protect medical staff, visitors and patients from microbial and body fluid transfer in the case of patient isolation. Medical gowns can also be used to protect visitors in the medical environment. According to the isolation and prevention guidelines of the Centers for Disease Control and Prevention, during surgery and patient care activities, when expected to contact clothes, blood, body fluids, secretions and excreta, wear medical isolation clothing to protect the arms of medical staff and exposed body areas.
Medical gowns are widely used in intensive care units (ICU), infectious diseases departments and infectious disease hospitals in general hospitals. At present, there are disposable and non disposable medical gowns in clinical use. Disposable medical isolation clothing is expensive, and a large amount of use will cause great waste. There are many problems with non disposable medical isolation clothing: collar, cuff and abdomen are easy to be polluted, which reduces the use time of medical isolation clothing; The design of cuff, back and bottom is defective, which is easy to pollute the working clothes of staff; The fabrication material is not waterproof. Studies have shown that there are many factors that cause hospital infection, among which the way of direct contact infection is that medical staff and caregivers spread pathogenic microorganisms or infectious substances planted by themselves to patients through contact to cause infection, while medical staff wearing medical isolation clothing can effectively prevent and control the occurrence of hospital infection.
2. What is isolated by medical isolation clothing
ASTM F3352-19 specifies that medical gowns are designed to protect medical staff, patients and visitors from the influence of blood, body fluids and other potential infectious substances during patient care or treatment. The main emphasis here is on blood and body fluids, and there is no mention of viruses transmitted through the air, such as COVID-19.
ASTM F3352-19 specifies "360 ° coverage", that is, at least ensure that the front, side and rear of the arm and body are completely covered from the knee to the neck (excluding the neck) during the movement. We can see that the protection range of medical isolation clothing is from knee to neck (excluding neck), not from head to foot. The head, neck, hands and feet are not within the protection range.
3. What is the difference between medical isolation clothing and protective clothing
GB 19082-2009 [3] stipulates that protective clothing is applicable to provide barrier and protection for medical personnel to contact with potentially infectious patients' blood, body fluids, secretions, particles in the air, etc. during work. Protective clothing consists of hooded jacket and pants, and can be divided into one-piece structure and split structure. One piece and split structure.
Medical isolation clothing is a kind of protective equipment used by medical personnel to prevent blood, body fluid and other infectious substances from contaminating them, and also to protect patients from infection. Contact with patients with infectious diseases transmitted by contact, such as patients with infectious diseases and patients infected with multidrug resistant bacteria; Protective isolation shall be carried out for patients, such as patients with extensive burns and patients with bone graft; Prevent infection when patients' blood, body fluids, secretions and effluents splash. In a word, medical isolation clothing is used for patients in tight isolation, contact isolation and protective isolation.
Medical and nursing protective clothing is a disposable protective equipment worn by medical staff when they are in clinical contact with Class A infectious disease patients or those under the management of Class A infectious diseases. When contacting patients with infectious diseases transmitted by air and droplets, they may be splashed by patients' blood, body fluids, secretions and emissions. But this kind of patient is not very serious, just a general infection.
