Is the overalls just work clothes? Youre wrong

Characteristics and application of cotton operating clothes

Cotton surgical clothes are constantly worn by medical staff. The cotton material is comfortable and breathable, but it has poor barrier function. It has no waterproof and anti penetration functions. It has low strength and is not washable. Repeated washing is easy to lead to breakage and debonding, and then environmental particles occur. These environmental particles become the carrier of pathogenic bacteria, easy to form allergy, infection and so on.

"Operating room (Department) hospital infection control standard" clear rules: medical staff brush hand clothing, operating clothing fabric should be comfortable, breathable, anti penetration, moderate thickness, fiber is not easy to fall, static electricity; after use, timely cleaning, disinfection or sterilization. The operating department (room) shall be equipped with group protective equipment to avoid blood and body fluid soaking and splashing, such as protective glasses, masks and full covering surgical caps, which shall meet the requirements of YY / T 0506.2-2009.

In recent years, more and more clean operating rooms have been designed and built in accordance with GB 50333 "technical standards for the establishment of clean operating departments in hospitals". As a clean environment, operating rooms should adhere to their cleanliness in the process of operation and try to increase the purification. However, cotton fabrics often used, such as surgical sheets, surgical clothes and hole towels, which are washed for a long time, are easy to lose the floc, and fly with the operation of air supply and exhaust fragmentary, resulting in the blockage of high-efficiency filter screen, so that the air supply volume and pressure difference can not meet the original design requirements of clean operation Department.

Therefore, the coarse and medium efficiency filter screen with fragmentary air supply and exhaust should be cleaned every three months, and the high-efficiency filter should be changed once a year. The terminal high-efficiency filter should be reviewed once a year. When the resistance exceeds the design initial resistance by 160pa or has been used for more than 3 years, it should be replaced. In addition, we also need to reflect on the air return filter screen, which needs to be cleaned once every three months and changed once a year. In this way, the cost of equipment maintenance will be added. If the cotton fabric is not used and the occurrence of cotton wadding is increased, then the operation cost of cleaning and changing the filter screen will be reduced, and the purification will also increase.

Characteristics of a surgical gown

The non-woven fabric material of a surgical suit has certain advantages in terms of comfort. In addition, if the consumption process is not properly controlled, the air permeability of the non-woven fabric can not be guaranteed, which makes the user wearing the operating suit feel stuffy and comfortable in the long-term operation process. Because of the low humidity resistance of the operating clothes, the antibacterial function is better. It also has an important feature that a small amount of medical waste will occur, adding the cost of disposal, forming environmental purification.

Characteristics of new composite membrane data

The inner and outer layers of the new composite membrane are ordinary fabrics or fabrics with waterproof, antistatic and anti pilling functions. The two end layers are bonded with medical membrane, which can effectively block the penetration of blood, bacteria and even viruses. Meanwhile, the water vapor generated by the skin of medical personnel can also penetrate through the medical film to ensure the physiological comfort of wearing. Polyester material can be selected as the textile material for the appearance of this kind of surgical dress. Its strength and toughness, washing times and service life are higher than those of cotton surgical dress. If the correct washing method is adopted, it can be used repeatedly for more than 100 times.

Development of operating clothes

Our country formulates the national standard YY / T 0506 according to en13795. Some enterprises have researched and recovered the new medical material fabrics with independent property rights. Compared with YY / T 0506 of the United States, Europe and China, the standards of hydrostatic pressure test, liquid permeability, blood permeability and microbial permeability were not compared. The functional test objectives of the US standard AAMI PB-70, European standard enl3795, and national standard YY / t0506-2005 were used for the functional test of surgical clothes. According to the three different standards, the operating clothes are divided into red secondary protection area and main protection area. The parts that are easy to contact with blood are the secondary protection areas, which need to use the data with higher protection function. AAML divides the protective function of surgical clothes into four levels

Level 1 (Level 1) is used for liquid exposure, radiation and sputtering risk is very low, and the operating clothes are subject to minimal pressure, such as eye surgery, breast tumor resection and skin in vivo reflection.
