Quality requirements for medical compressed air
The quality requirements for medical compressed air are very strict to ensure its safety and effectiveness in the medical process. The following are the main quality requirements for medical compressed air: 1. Cleanliness requirements
- Bacterial and microbial control: Medical compressed air must meet the standards of sterile or low microbial content. Specific requirements include the total number of bacteria and actinomycetes should be less than 100cfu/m³ (colony formation units per cubic meter) to ensure that no bacteria or other harmful substances are introduced during the medical process.
- Impurity removal: The impurities such as oil fume, moisture, solid particulate matter, and odor in the air must be effectively filtered and removed. Medical compressed air should be strictly filtered and purified to ensure its purity.
- Oil content control: The oil content of medical compressed air should be less than 0.1mg/m³. The presence of oil may cause contamination to medical equipment and affect the health of patients.
2. Stability requirements
- Flow and pressure stability: The flow and pressure of medical compressed air must be stable and there must be no sudden changes. Because oxygen mixed with oxygen and anesthetics are required during the operation, if the oxygen flow and concentration suddenly change, it may pose risks to the patient.
- Physical parameters are stable: The temperature of medical compressed air should be kept between 5℃ and 40℃, and the humidity should be kept between 25% and 75%. Too high or too low temperatures and humidity may have an impact on the patient’s health.
3. Comply with specific standards
- National Standards: The quality standards for medical compressed air are generally stipulated by national health departments or industry standards. In China, the standards for compressed air for medical use are standardized by the “Hospital Compressed Air Quality Standard” (GB/T 14213-2013).
- International Standards: The production and supply of medical compressed air must also comply with relevant international standards, such as ISO 7396-1 “Design, Installation Verification Requirements for Air and Oxygen Pipeline Systems in Medical Institutions” and ISO 13485 “Requirements for Medical Devices-Quality Management Systems”.
IV. Other requirements
- Routine testing: Hospitals and medical institutions must conduct regular testing of medical compressed air to ensure that its quality always meets the use requirements. The detection content includes oil content, microbial, physical parameters, etc.
- Equipment Requirements: Medical CompressionThe production and supply equipment of air must comply with relevant safety standards and be able to provide stable and sterile compressed air. These equipment usually include air compressors, dryers, filters and control systems.
5. Application importance
Medical compressed air has a wide application and importance in the field of medicine. For example, it provides pure compressed air to the ventilator, ensuring that the ventilator can accurately control pressure and flow, and provide patients with sufficient oxygen; it serves as an important gas source for the anesthesia machine, supporting the supply of gas during the anesthesia process; it serves as a spray therapy medium for treating patients with respiratory diseases, etc.
In general, the quality requirements for medical compressed air are very strict to ensure its safety and effectiveness in the medical process. When medical institutions use and detect medical compressed air, they must operate in accordance with relevant standards and testing methods.
