How to distinguish the level of laminar flow purification operating room

The sterile laminar flow purification operating room can effectively reduce the postoperative infection rate and help patients recover as soon as possible. Human and Purification introduces you to the classification of laminar flow operating rooms and the characteristics of a sterile laminar flow operating room.

Laminar operating room features

1. The number of bacteria in the operating room is low.

2, for comfortable airflow (indoor temperature can be 15-25 ° C, humidity can be adjusted between 50-65%).

3. The positive pressure airflow (+23-25Pa) in the operating room prevents the entry of external pollution.

4, the operating room air is fresh, clean, and the working environment is comfortable.

5, laminar flow purification operating room, under normal circumstances without the use of physical or chemical methods for disinfection,

Class 100 (especially clean) valve replacement, cardiac surgery, organ transplantation, artificial joint replacement, neurosurgery, and surgery.

Class 1 (standard clean) ophthalmology, orthopedics, non-systemic burns, orthopedics, general surgery, and hepatobiliary and pancreatic surgery.

Class 10 000 (general clean) thoracic surgery, urology, obstetrics and gynecology, otolaryngology, general surgery, removal of the operating room, sterile room.

100 000 (general clean) outpatient, emergency, infection surgery, generalized burn corridor, restroom, anesthesia preparation room.

Different levels of laminar flow purification operating room laminar flow system, the air replacement rate in the control space environment is also different, the higher the cleanliness level, the faster the replacement rate, and vice versa. The laminar flow operating room wall is coated with a special paint that has a bacteriostatic effect. The light is bright, the color is soft and it does not need to be cleaned with water.

Laminar flow purification operating room level distinction

I 0.4 / 30minφ90 (10 / m3) 5 / cm2 1000 (partial 100)

II 1.5 / 30min φ 90 dishes (50 / m3) 5 / cm2 10000

III 4 / 30min φ 90 (150 / m3) 5 / cm 2 100000

IV 5 / 30min φ 90 (175 / m3) 5 / cm 2 300000
