Disposable isolation gown, disposable protective gown and disposable surgical gown are commonly used personal protective equipment in hospitals. But in the process of clinical supervision, there are often medical staff confused with the three. After searching the information, I'll talk about the similarities and differences of the three from the following aspects.

I. Function

Disposable isolation gown : it is used for medical personnel to avoid being polluted by blood, body fluids and other infectious substances, or for protecting patients from infection. Isolation gown is a kind of two-way isolation, which can not only prevent medical staff from being infected or polluted, but also prevent patients from being infected.

Disposable protective gown: disposable protective equipment worn by clinical medical personnel when contacting with patients with Class A or infectious diseases managed according to class A infectious diseases. Protective gown is to prevent medical staff from being infected, which is a single isolation.

Disposable surgical gown: the surgical gowns play a two-way protective role in the process of operation. First of all, the surgical gown establishes a barrier between the patient and the medical staff, which reduces the probability of the medical staff contacting the patient's blood or other body fluids and other potential sources of infection during the operation; second, the surgical gown can block the transmission of various bacteria adhering to the skin or the surface of the medical staff to the surgical patients, effectively avoiding the cross infection of multi drug resistant bacteria. Therefore, the barrier function of the surgical gown is considered as the key to reduce the risk of infection during the operation.

2. Application scenario

Disposable isolation gown: 1. Contact with patients with infectious diseases transmitted by contact, such as patients infected with multidrug-resistant bacteria, etc. 2. When carrying out protective isolation for patients, such as diagnosis, treatment and nursing of large area burn patients and bone transplant patients. 3. May be splashed by the patient's blood, body fluids, secretions, and excretions. 4. Whether to wear isolation clothes when entering key departments such as ICU, NICU, protective ward, etc. depends on the purpose of medical personnel entering and the contact with patients.

Disposable protective gown: 1. In contact with Class A or patients under Class A infectious disease management. 2. When contacting suspected or confirmed SARS, Ebola, MERS, H7N9 avian influenza and other patients, the latest infection control guidelines shall be followed.

Disposable surgical gown: after strict aseptic disinfection, they are used in special operating room for patients' invasive treatment.

3. Appearance and material requirements

Disposable isolation gown: disposable isolation gown is usually made of non-woven materials or combined with materials with better impermeability, such as plastic film. It has integrity and toughness through the use of various non-woven fiber joining technologies instead of the geometric interlock of knitting and knitting materials. The isolation gown shall be able to cover the trunk and all the clothes to form a physical barrier for the spread of microorganisms and other substances. It shall be impermeable, wear-resistant and tear resistant. The isolation suit can be reused or disposable, without a hat, and it can be waterproof or not.

Disposable protective gown: GB 19082-2009 clearly points out that protective gown consists of hooded top and pants. It can be divided into one-piece structure and one-piece structure. The trouser legs and cuffs are tightened, and the protection level of protective gown is higher than that of isolation gown. It is generally recommended to use disposable. The standard clearly points out that the protective gown must have liquid barrier function (anti water permeability, moisture permeability, anti synthetic blood penetration, surface moisture resistance), flame retardant performance and anti-static property, and has requirements for breaking strength, breaking elongation, filtering efficiency, etc.

Disposable surgical gown: domestic and international standards have clear requirements for barrier, strength, microbial penetration, comfort and so on. The operation clothes should be impermeable, sterile, conjoined, and have no hat. Generally, the cuffs of the surgical gown are elastic, easy to wear and convenient to wear sterile gloves. It is not only used to protect medical staff from contamination by infectious substances, but also used to protect the sterile state of the exposed parts of the operation.

To sum up, from the appearance, protective gown is very different from isolation gown and surgical gown. It's not easy to distinguish the surgical gowns from the isolation gowns. It can be based on the length of the belt (the belt of the isolation gowns should be tied to the front for easy removal). The waistband of the surgical gown is tied at the back). The functions of the three have a place of intersection. The requirements of   disposable surgical gown   and protective gown are significantly higher than those of disposable isolation gown. In the case of common use of isolation gown (such as contact isolation of multi drug resistant bacteria), disposable surgical gown and isolation gown can communicate, but the place where disposable surgical gown must be used cannot be replaced by isolation gown. The use of the three is an important measure to prevent and control infection in hospitals, which plays an important role in protecting patients and medical workers.
