Clean Room Supplies Manufacturers: How To Organise The Clean Room For Hospital

Youth is the clean room supplies manufacturers in China, our main products are air filter, purification equipment, cleanroom furniture, cleanroom panel system.

Clean technology is also called clean room technology. In addition to meeting the conventional temperature and humidity requirements of air-conditioned rooms, through various facilities and strict management in engineering technology, the content of indoor particles, airflow, and pressure are also controlled within a certain range.

This kind of room is called a clean room. With the development of medical and health undertakings and high technology, the application of clean technology in the medical environment has become more extensive, and the technical requirements for itself have become higher. The clean rooms used in healthcare are mainly divided into three categories: clean operating rooms, clean nursing wards and clean laboratories.

Clean operating room from clean room supplies manufacturers:

The clean operating room takes indoor microorganisms as the control target, operating parameters and grading indicators, and air cleanliness is a necessary guarantee condition. The clean operating room can be divided into the following levels according to the degree of cleanliness:

1.Special clean operating room: The cleanliness of the operating area is grade 100, and the surrounding area is grade 1,000. It is suitable for aseptic operations such as burns, joint transformation, organ transplantation, brain surgery, ophthalmology, plastic surgery and heart surgery.

2.Clean operating room: The cleanliness of the operating area is grade 1,000, and the surrounding area is grade 10,000. It is suitable for aseptic operations such as thoracic surgery, plastic surgery, urology, hepatobiliary and pancreatic surgery, orthopedic surgery, and egg retrieval.

3.General clean operating room: The cleanliness of the operating area is class 10,000, and the surrounding area is class 100,000, which is suitable for general surgery, dermatology, and abdominal surgery.

4. Quasi-clean operating room: The air cleanliness is 100,000, suitable for obstetrics, anorectal surgery and other operations. In addition to the cleanliness level and bacterial concentration of the clean operating room, the relevant technical parameters should also meet the relevant regulations. See the main technical parameter table of the clean operating room at all levels. The plane layout of the clean operation department should be divided into two parts:

Clean area and non-clean area according to general requirements. The operating room and the functional rooms directly serving the operating room should be located in a clean area. When people and objects pass through areas of different cleanliness in the operating department, airlocks, buffer rooms or pass box should be provided. Generally, the operating room is located in the core part. The internal plane and channel form should conform to the principle of quick functional flow and clear cleanliness.

Several clean care wards in the hospital:

The clean care wards are divided into isolation wards and intensive care wards. The isolation ward is divided into four levels of P1, P2, P3, P4 according to the biological risk. The P1 ward is basically the same as the ordinary ward, and the entry and exit of outsiders is not specifically prohibited; the P2 ward is stricter than the P1 ward, and outsiders are generally prohibited from entering and exiting; the P3 ward is isolated from the outside by a heavy door or buffer room, and the internal negative pressure of the room is isolated; the P4 ward is isolated The area is separated from the outside world, and the indoor negative pressure is constant at 30 Pa.

Medical staff wear protective clothing to prevent infection. Intensive care units include ICU (intensive care unit), CCU (cardiovascular patient care unit), NICU (premature infant care unit), leukemia unit and so on. The room temperature of the leukemia room is 242, the wind speed is 0.15~0.3/m/s, the relative humidity is below 60%, and the cleanliness is class 100. At the same time, the cleanest air sent in should reach the patient’s head first, so that the mouth and nose breathing area is supplied with air, horizontal flow is better.

Bacterial concentration measurement in the burn ward showed that the vertical laminar flow has obvious advantages for open treatment, the layer injection speed is 0.2m/s, the temperature is 28-34, and the cleanliness is class 1,000. Respiratory wards are rare in China. Such wards have strict requirements on indoor temperature and humidity. The temperature is controlled at 23-30%, and the relative humidity is 40-60%.

Each ward can be adjusted according to the patient, and the cleanliness is controlled at 10~ Between class 10,000, the noise is less than 45dB(A), and personnel entering the ward should undergo personal purification such as changing clothes, blowing and showering, and maintaining positive pressure in the ward.

Clean laboratory clean room supplies manufacturers: 

Clean laboratories are divided into ordinary clean laboratories and biosafety laboratories. Experiments conducted in ordinary clean laboratories are not infectious, but the environment is required to not cause adverse effects on the experiment itself. Therefore, there are no protective facilities in the laboratory, and the cleanliness must meet the experimental requirements.
The biosafety laboratory is equipped with first-level protection facilities, which can realize the biological experiment of the second-level protection.

Biosafety laboratories are required for scientific experiments in the fields of microbiology, biomedicine, functional experiments, and genetic recombination. The core of the biosafety laboratory is safety, which is divided into four levels: P1, P2, P3, and P4 according to the degree of biological risk.

The P1 laboratory is suitable for a very familiar source of disease, which does not often cause diseases in healthy adults, and is less dangerous to laboratory personnel and the environment. The door should be closed during the experiment, and the operation shall be carried out according to the ordinary microbiological experiment; P2 laboratory is suitable for disease sources with medium potential danger to humans and the environment.

Restricted access to the experimental area, experiments that may occur aerosols should be carried out in a level II biological safety cabinet, and an autoclave should be equipped; P3 laboratories are used in clinical, diagnostic, teaching, or production facilities, and are carried out in this level. Work on endogenous and exogenous disease sources, if exposed and inhaled the disease source will cause serious and potentially fatal diseases.
The laboratory is equipped with a double door or airlock room and an externally isolated experimental area. Non-workers are prohibited from entering the laboratory. The laboratory is under negative pressure. The experiment is carried out with a Class II biological safety cabinet. The indoor air is filtered by a high-efficiency filter and discharge it to the outdoors;
P4 laboratories have stricter requirements than P3 laboratories. Some dangerous exogenous disease sources have a high individual risk of laboratory infections and life-threatening diseases due to aerosol transmission. The relevant work should be carried out in P4 laboratories.
It adopts the structure of independent isolation area and external partition in the building, maintains negative pressure indoors, uses Class III biological safety cabinet to conduct experiments, installs air partition device, shower room, operating staff should wear protective clothing, non-workers of this department are prohibited get inside. The core of the design of the biosafety laboratory is dynamic isolation. The exhaust measures are the key point. It emphasizes on-site disinfection, attaches importance to clean dirt diversion, and prevents accidental spread. It requires moderate cleanliness.
