Emerging infectious diseases, the threat of pandemic influenza and viral respiratory disease highlights to protect medical staff and patients.
Personal protective equipment (
Is the key to prevent the spread of infectious diseases, especially blood pathogens.
Personal protective equipment, including protective clothing, isolation, medical gloves, goggles, mask mask and head/shoe covers, etc.
OSHA requirements in patients during treatment use prevention measures, such as the PPE, in order to prevent the microbiology and infectious, especially blood-borne pathogens through.
According to the centers for disease control (
Isolation precautions and prevention guidelines, the expected with clothes, blood, body fluids, and patient care activities in the process of contact, should wear protective clothing to protect medical staff arm and bare parts of the body.
Secretions and excretions.
Protective clothing is considered to be second to the glove personal protective equipment (
Isolation gown resistance to blood and other body fluids with different, depending on the type of material, its impermeability and wear.
About the routine use of gowns will reduce the infection rate of the mixed together.
Some studies show no benefit.
During the period of patient care activities, the PPE may be exposed to microbes, droplets or aerosol pollution from patients with body fluids.
They have to microbial spread from one place to another place of potential.
In one study, in the routine clinical nursing staff work clothes and/or detection of MRSA on gloves or VRE as low as 4% and as high as 67%.
Many studies have found that the nurse uniform often polluted, and is spread through the uniform.
In the isolation ward, found that staphylococcus aureus accounted for 12 on the cotton-padded clothes.
6%, plastic apron of 9.
2%, uniforms, accounted for 15%.
Paramedics coat and uniform the possibility of contamination by pathogenic bacteria was 63%, 50% of all the samples of pathogenic bacteria is positive.
According to the materials used in the PPE and the relative humidity of the air, the persistence of the virus may last a few weeks to a few months.
In the United States, about 80% of the use of disposable hospital disposable gowns and surgical drapes.
They are usually made of nonwoven synthetic materials, in order to enhance the protection of liquid penetrant, such as plastic film (
Polypropylene, polyester, polyethylene)
Reusable insulating clothing is more popular in Europe.
They are usually made of 100% cotton, 100% polyester fiber or polyester/cotton blended fiber, and through chemical finishing in order to enhance the protection of liquid.
They must be cleaned after each use, and is typically used for 50 or more washing/drying cycle.
Usually, disposable gowns cheap and easy to mass production.
But the recent global pandemic quickly run out of supplies, it is almost impossible to obtain sufficient protective equipment to protect medical staff.
Health care facilities and the EMS must be creative, and explore alternatives to surgery and isolation.
In addition, organizations are looking for a more environmentally friendly alternatives, the alternatives will not produce a large number of medical wastes contain potentially dangerous virus.
Guangdong is also committed to the r&d of new products, environmental protection and sustainable development road.
