Hundreds of levels, thousands, and 10,000-level operating room

Production and development of laminar flow operating room

With the development of medical development, the development of surgery technologies requires high-profit net surgical environment, large-scale burn surgery, craniocerebral surgery, ophthalmology, lung surgery, longitudinal surgical surgery, etc., it must be carried out in ultra-clean environments, in large Limited to reduce the surgical infection rate to ensure successful surgery. The laminar flow operating room has become a major revolution in the operating room for the development of the operating room, so that the success rate of surgery rose a new step.

Lamination operating room

Lamidity pure net operating room is a multi-function using air clean measures utilizationair filterEquipment, filtering dust particles in the air, making bacterial without carrier, thereby effectively preventing and controlling infection, while providing a suitable temperature, humidity environment, making the patient under surgery as little damage as possible.

Lamidal operating room air pureness level

According to the Ministry of Construction, \"Hospital Clean Surgery Building Technical Specifications (GB5033-2002)\", laminar flow operating room air cleanliness can be divided into three levels, thousands, thousands, 100,000 and 300,000 levels.

1) Clean level 100

The number of dust particles greater than or equal to 0.5 μm is greater than 350 capsules / m3 (0.35 bits / L) to less than or equal to 3500 capsules / m3 (3.5 grain / L); the number of dust particles greater than or equal to 5 μm is 0.

2) Clean degree 1000

The number of dust particles larger than or equal to 0.5 μm is greater than 3,500 capsules / m3 (3.5 granules / L) to less than or equal to 35000 and M3 (35 particles / L); greater than or equal to 300 particles / m3 (0.3 granules / L).

3) Clean degree is 100,000

The number of dust particles greater than or equal to 0.5 μm is greater than 35,000 pieces / m3 (35 pieces / L) to less than or equal to 350000 capsules / m3 (350 grain / L); greater than 300 particles / m3 (0.3 granules / L) ) To less than or equal to 3000 pieces / m3 (3 capsules / L).

4) Clean degree is 100,000

The number of dust particles greater than or equal to 0.5 μm is greater than 350,000 pieces / m3 (350 capsules / L) to less than or equal to 3500,000 pieces / m3 (3500 capsules / L); greater than 30,000 dust particles above 3000 capsules / m3 (3 capsules / L) ) To less than or equal to 30000 capsules / m3 (30 capsules / L).

5) Clean degree 300000

The number of dust particles greater than or equal to 0.5 μm is greater than 3500,000 pieces / m3 (3500 capsules / L) to less than or equal to 1050,000 pieces / m3 (10500 grain / L); greater than 30,000 dust particles above 30000 capsules / M3 (30 capsules / L) ) To less than or equal to 900,000 pieces / m3 (90 capsules / L).

The clean operating department is divided into four levels, and the air cleanliness level is used as a necessary guarantee condition:

Cleaning operating room level standard (empty or static):

grade	Operating room name	Settlement method (floating method) bacterial maximum average concentration		Surface maximum style density (single / cm2)	Air cleanliness level
		Surgical area	Peripheral area		Surgical area	Peripheral area
Ⅰ	Special clean operating room	0.2 / 30min · φ90 dish (5 / m3)	0.4 / 30min · φ90 dish (10 / m3)	5	Level 100	Level 1000
Ⅱ	Standard clean operating room	0.75 / 30min · φ90 dish (25 / m3)	1.5 / 30min · φ90 dish (50 / m3)	5	Level 1000	Level 100,000
Ⅲ	General clean operating room	2 / 30min · φ90 dish (75 / M3)	4 / 30min · φ90 dish (150 / m3)	5	Level 100,000	100000 level
Ⅳ	Standard room	5 / 30min · φ90 dish (175 / m3)		5	300000
