Classification of laminar ventilation ceiling in operating room
Classification of laminar ventilation ceiling in operating roomLevel 100 (Level I): The "king" of top purificationThe hundred-level air supply ceiling called the "king" of the operating room air supply ceiling, corresponds to Class 100 or ISO Class 4 standards, representing the top level of purification. It uses the most advanced air filtration technology, equipped with a high-efficiency filter that can effectively intercept dust particles in the air with a particle size greater than or equal to 0.5μm, the number of such particles per cubic meter of air does not exceed 3520, and the filtration efficiency of microorganisms is as high as 99.99%. It can almost wipe out harmful organisms such as bacteria and viruses in the air. In cardiac surgery, the heart is the most critical organ in the human body. Even the extremely small dust particles or microorganisms entering the body during the operation may cause serious infection, leading to the failure of the operation and even endangering the life of the patient. The 100-stage ventilation ceiling can provide a nearly perfect clean environment for heart surgery, greatly reducing the risk of infection and improving the success rate of surgery. Neurosurgery is the same, the brain is the nerve center of the human body, the surgical operation is delicate and complex, and the cleanliness of the environment is very high, the existence of a 100-level ventilation ceiling provides a reliable guarantee for neurosurgeons in the operation, so that they can be more focused on the operation. Thousand-level (II): Balance of performance and cost The thousand-grade ventilation ceiling corresponds to the Class 1,000 or ISO Class 5 standard, which is slightly inferior to the hundred level in purification capacity, but it is also a strong guarantee of air quality in the operating room. Its filter also has a high filtration efficiency, and can effectively filter particles and microorganisms in the air, per cubic meter of air particle size greater than or equal to 0.5μm dust particles number does not exceed 35,200. Eye surgery, especially some delicate surgeries such as cataract phacoemulsification and keratoplasty, has a high requirement for the cleanliness of the operating environment. Because the eye is a very sensitive organ, if there are pollutants in the operation process, it is easy to cause an eye infection, affect the operation effect, and even lead to blindness. The clean environment provided by the thousand-grade air supply ceiling can meet the requirements of eye surgery. At the same time, compared with the hundred-grade air supply ceiling, its cost is relatively low, and a good balance is found between purification efficiency and economy so that the hospital can control the cost reasonably while ensuring the quality of surgery. Class 10,000 (Class III): Reliable guarantee for routine surgery The Class 10,000 ceiling corresponds to the Class 10,000 or ISO Class 6 standard and is commonly used in routine surgery and other less sensitive medical operations. Through reasonable airflow organization and filtration system, it can effectively remove large particles of dust and some microorganisms in the air, and the number of dust particles with a particle size greater than or equal to 0.5μm per cubic meter of air does not exceed 352,000. Some general surgical procedures, such as appendicitis excision, hernia repair, etc., although the requirements for cleanliness are not as strict as cardiac surgery, and neurosurgery, also need a relatively clean operating environment to reduce the risk of infection. The 10,000 air supply ceiling can provide a reliable guarantee for these routine operations, ensure the cleanliness of the air during the operation, and create a safe and comfortable operating environment for patients. |
