The current situation and future development of Jianwei medical equipment operating clothes

In recent years, with the deepening understanding and attention of the blood borne pathogens from time to time in the medical field, more and more attention has been paid to the protective measures taken by doctors and patients during the operation process. A number of studies have fully demonstrated that there is a risk of removing blood borne pathogens such as HIV, HBV, HCV and so on. All these viruses can be stopped by blood contact with damaged skin or mucosa. The United States is the first country in the world to adopt the standard of operating clothes and sheets. OSHA announced rules in 1991 to reduce the risk of medical staff contacting blood to transmit pathogens. The rules require that medical staff should use appropriate personal protective equipment (PPE) to avoid contact with infectious sources. EU countries have also passed and implemented the guidelines for medical devices (93 / 42 EEC), which has been invalid since June 1998 and has become a mandatory law in EU countries, which defines surgical clothes as medical devices. The corresponding commercial specification of surgical clothing is en3795. With the promotion of time and rich theoretical experience, China has also issued a series of relevant specifications (YY / t0506-2005), which, like the European Union en3795, divides surgical clothing into standard type and primary type, and divides the secondary protection area and main protection area map. In terms of test objectives, only the comfort test is added on the basis of EU en3795 to meet the comfort requirements of clinical application. The protective function of surgical clothing data can be divided into four levels: the United States is the first country in the world to adopt the standard of operating clothes and shop orders. The occupational safety and Health Administration (OSHA) announced the rules in 1991. According to the requirements of OSHA protection rules, the American Association for the promotion of medical devices (AAMI) divides the protective function of surgical clothes into four levels: Level 1 1) : for liquid exposure, radiation and sputtering risk is very low, the operating clothes are subject to minimal pressure as follows: eye surgery, breast tumor resection and skin in vivo reflection and other operations or operations. Level 2: it is used for large amount of liquid exposure, low risk of radiation and sputtering, and low pressure on surgical clothes, such as hernia repair, tonsillar surgery and angiography. The operation clothes of this grade must be tested by water resistance and hydrostatic pressure test. The third level (Level 3): the operating clothes are used for medium liquid exposure, radiation and sputtering risks, and have high pressure on the operating clothes, such as shoulder arthroscopy, prostate resection and mastectomy and other similar operations and operations. The level of surgical clothing has higher requirements for water leakage and static voltage test. Level 4: it is used for a small amount of liquid exposure, high risk of radiation and sputtering, and high pressure on the operating clothes, such as hip replacement, caesarean section, cardiovascular surgery, and the operation and operation that all medical professionals will enter the patient's body. This level requires a blood immersion test after surgery. Level 4 high function protective operating suit has five functions of waterproof, antifouling, anti soaking, anti alcohol and anti-static. It can eliminate the blood and body fluid of patients and infect the operating doctors and nurses. It has good air permeability and comfortable and heavy wearing. It does not take off floc, increases the risk of wound infection in operating room and increases the maintenance cost of ventilation equipment in operating room. The blocking rate of rare pathogenic bacteria in hospital can reach 100% It has the function of inhibiting bacteria. All the functional requirements are beyond the European and American specifications and the relevant series of Chinese specifications (YY / t0506-2005). EU countries have also passed and implemented the guidelines for medical devices (93 / 42 EEC), which has been invalid since June 1998 and has become a mandatory law in EU countries, which defines surgical clothes as medical devices. The corresponding commercial specification for surgical clothing is en3795, which divides the surgical clothing into standard type and primary type. The finished product is divided into secondary protection area and primary protection area, and hydrostatic pressure and dry and wet bacterial penetration test are used as barrier function specifications in the test target to replace decomposing blood and microbial penetration test in American specification.
