Interpretation of medical isolation gown standards

What is a medical isolation gown

There are currently no national standards and industry standards for medical isolation gowns. The American standard ASTM F3352-19 defines medical isolation gowns as the protection used to protect medical staff, visitors and patients from the transfer of microorganisms and body fluids under patient isolation. Medical gowns can also be used to protect visitors in the medical environment. According to the isolation prevention guidelines of the Centers for Disease Control and Prevention, during surgery and patient care activities, when contact with clothing, blood, body fluids, secretions and excrements are expected, wear medical isolation gowns to protect the arms and exposed body areas of medical staff.

Medical gowns are widely used in the intensive care unit, infectious disease department and infectious disease hospitals of general hospitals. At present, there are two types of medical gowns in clinical use: disposable and non-disposable. Disposable medical isolation gowns are more expensive, and large-scale use will cause a lot of waste. There are many problems in non-disposable medical isolation gowns: the collar, cuffs, and abdomen are easily contaminated, which reduces the use time of medical isolation gowns; the design of cuffs, backs, and bottoms are defective, which may easily contaminate the work clothes of the staff; Waterproof etc. Studies have shown that there are many factors that cause nosocomial infections. Among them, direct contact with the infection is that the pathogenic microorganisms or infectious substances colonized by the medical staff and escorts spread to the patients through contact, and the medical staff can effectively prevent the infection by wearing medical isolation gowns. And control the occurrence of nosocomial infections.

What does the medical gown isolate?

ASTM F3352-19 stipulates that medical isolation gowns are designed to protect medical staff, patients and visitors from blood, body fluids and other potentially infectious substances during patient care or patient treatment. The main emphasis here is blood and body fluids, and no mention is made of viruses that spread through the air, such as the new coronavirus.

ASTM F3352-19 stipulates "360° coverage", that is, at least ensure that the front, side and back of the arm and body are completely covered from the knee to the neck during exercise. We can see that the scope of protection of medical isolation gowns is from knee to neck, not from head to toe. The head, neck, hands, and feet are not covered.

What is the difference between medical isolation clothing and protective clothing?

GB 19082-2009 stipulates that protective clothing is suitable for providing barriers and protection for medical staff from contact with potentially infectious patients’ blood, body fluids, secretions, and particulate matter in the air. The protective clothing consists of hooded tops and pants. The composition can be divided into two-piece structure and two-piece structure. One-piece and two-piece structure.

Medical isolation gowns are protective equipment used by medical personnel to avoid contamination by blood, body fluids and other infectious substances when in contact, and are also used to protect patients from infection. Contact patients with infectious diseases spread by contact, such as patients with infectious diseases and patients infected by multi-drug resistant bacteria; implement protective isolation of patients, such as patients with extensive burns and bone transplant patients; prevent patients from blood, body fluids, Infected when secretions and feces are splashed. In short, medical isolation gowns are used for patients in tight isolation, contact isolation and protective isolation.

Medical protective clothing is a disposable protective equipment worn by medical staff when they are in contact with patients with Class A or infectious diseases managed by Class A infectious diseases. When contacting patients with airborne and droplet-borne infectious diseases, they may be splashed by the patient's blood, body fluids, secretions, and feces. But this kind of patient is not very serious but just a general infection.
