Laminar flow operating room classification standards
Laminar flow clean operating room mainly clean air technology, the microbes surgery space varying degrees of control, so that the indoor air reaches a certain cleanliness, to apply to all types of surgical requirements, and has optimum temperature and humidity suitable for surgery space environment, is an effective control room number of pathogens is essential to modern society sophisticated surgical facilities
Laminar flow operating room air purity level:
According to the Ministry of Construction "cleansing operation of the hospital building technical specifications (GB50333-2002)", laminar flow operating room air cleanliness can be divided into one hundred, one thousand, ten thousand, one hundred thousand and three hundred thousand five levels.
1) one hundred cleanliness:
Greater than equal to the number of dust particles larger than 0.5um 350 /m3(0.35 grain / L) less than or equal to 3500 /m3(3.5 grain / L); 5um number of dust particles greater than or equal to zero.
2) the cleanliness of one thousand:
Greater than equal to the number of dust particles larger than 0.5um 3500 /m3(0.35 grain / L) less than or equal to 35,000 / m3 (35 粒 / L); or greater number of particles of less than 5um /m3(0.3 equal to 300 grains / L).
3) The cleanliness of ten thousand:
Greater than equal to the number of dust particles larger than 0.5um 35,000 / m3 (35 粒 / L) less than or equal to 350,000 / m3 (350 粒 / L); greater than or equal 5um dust number of less than or equal 300 /m3(0.3 grain / L) less than or equal to 3000 / m3 (3 粒 / L).
4) The cleanliness of one hundred thousand:
Greater than or equal 0.5um more than 350,000 the number of dust particles / m3 (350 粒 / L) less than or equal to 3.5 million / m3 (3500 粒 / L); 5um than or equal to the number of dust particles of less than or equal 3000 / m3 (3 tablets / L) less than or equal to 3000 / m3 (30 粒 / L).
5) the cleanliness of three hundred thousand:
