What are the partitions of a clean operating room and what are the cleanliness levels of a laminar f

I don't understand what you mean, haha, clean does not mean dust-free, the operating room environment is a thousand-level, dust-free and sterile, Zhengzhou Zhanhong purification.

According to the Ministry of Construction's "Technical Specifications for the Construction of Hospital Clean Operating Departments (GB50333-2002)", the air cleanliness of laminar flow operating rooms can be divided into five levels: 100, 1000, 100,000, 100,000 and 300,000.

The laminar flow operating room adopts air cleaning technology to control the sources of microbial contamination to different degrees, so as to achieve the requirements of air cleanliness in the controlled space environment and suitable for various types of surgery. And provide appropriate temperature and humidity to create a fresh, clean, comfortable, and low bacterial count surgical space environment, so that patients can suffer as little tissue damage as possible during surgery, and greatly reduce the secondary infection rate of patients and medical staff, especially intracranial surgery and burn surgery, to ensure that patients can recover faster and better after surgery.

The clean operating room can usually be divided into 3 areas, namely: clean area, clean area, and contaminated area.

a.Cleaning area: including office, locker room, duty room, family waiting area, etc.

b.Clean area: including conversation room, anesthesia preparation room, sterile instrument room, operating room, clean corridor, etc.

c.Contaminated areas: polluted corridors, sewage washing rooms, isolation sewage washing rooms, packing rooms, etc.

Laminar flow purification of the operating room not only requires highly clean air (the air entering the operating room must first be purified by a high-efficiency filter), but also requires the flow direction of the airflow (i.e., the use of laminar flow ultra-clean device), so that the airflow flows from the surgical area with high cleanliness to the area with low cleanliness, and takes away and discharges the dust particles (dust particles) and bacteria in the airflow; Laminar flow is a fine, thin-layered stream of air that is transported in the same direction at a uniform flow velocity; There are two types of purified airflow: vertical laminar flow and horizontal laminar flow. The following is an introduction to the purification level and cleanliness level of China's operating room by Anhui Renhe and Purification.

Level differentiation of laminar flow decontamination operating rooms.

30min 90 dishes (10 m3) 5 cm2 1000 grade (local 100 grade).

30min 90 dishes (50 m3) 5 cm2 10000 grades.

4 x 30min 90 dishes (150 m3) and 5 x cm2 100000 grade.

5 x 30min 90 dishes (175 m3) 5 x cm2 300000 grade.

Cleanliness level Applicable type of surgery Room arrangement.

Class 100 (extra clean) Valve Replacement, Cardiac Surgery, Organ Transplantation, Joint Replacement, Neurosurgery, Operating Room.

Class 1 000 (Standard Clean) Ophthalmic Surgery, Plastic Surgery, Non-systemic Burns, Orthopedics, Class I Surgery in General Surgery, Hepatobiliary and Pancreatic Surgery Cardiopulmonary bypass perfusion preparation room.

Class 10 000 (General Clean) Thoracic Surgery, Urology, Obstetrics and Gynecology, Otorhinolaryngology, General Surgery (except for Class I surgery) Operating room, sterile room.

Class 100 000 (General Clean) Outpatient, Emergency, Infectious Surgery, General Burn Corridor, Restroom, Anesthesia Preparation Room.

Hello, the clean operating room is divided into 100 levels, 1000 levels, 100,000 levels, 100,000 levels and 300,000 levels, and the highest level is 100 levels.

The 100-level operating room refers to the operating room that needs to do some organ transplantation, heart and other important surgeries without bacteria.

The 1,000-level operating room is a type of sterile surgery such as thoracic surgery and plastic surgery.

The 10,000-level operating room is the general surgery and women's department of these minor surgeries.

In fact, it is the operating room divided by the dust level of each cubic meter of air in the operating room.

Generally, the operating room only has a general area (no need to purify), a 100,000-level area (an auxiliary area such as changing clothes, etc.), and a 10,000-level area (an operating area).

The clean operating room is generally divided into several levels, so you should go to the hospital and ask the relevant doctor or relevant books to check it.
