Medical compressed air

Medical compressed air refers to compressed air that has been specially treated to remove impurities and moisture to achieve sterility or low microbial content, and is specially used in medical equipment. It has a wide range of applications and importance in the medical field. The following is a detailed description of medical compressed air:

1. Definition and Characteristics

medical compressed air is compressed into a certain pressure by a compressor, and after strict filtration and purification treatment, the oil, moisture, solid particles and microorganisms and other impurities are removed to ensure that it is delivered to various medical equipment in a clean and sterile state. Its characteristics mainly include:

• sterile or low microbial content: Ensure that bacteria or other harmful substances are not introduced during medical procedures.
• Stable air pressure and flow: Meet the high requirements of medical equipment and procedures for gas source quality.
• Compliance with specific standards such as "hospital compressed air quality standards" (GB/T 14213-2013), to ensure that the quality of compressed air standards.

Main purpose of 2.

The main uses of medical compressed air in medicine can be summarized as follows:

1. directly used for human life respiratory system treatment:
   • ventilator: Provide pure compressed air for the ventilator to ensure that the ventilator can accurately control the pressure and flow, and provide sufficient oxygen for the patient.
   • anesthesia machine: It also serves as an important gas source for the anesthesia machine to support the gas supply during anesthesia.
   • spray therapy: As a spray therapy medium for the treatment of patients with respiratory diseases.
   • Premature infant incubator: When adjusting the oxygen concentration with the artificial respirator in the incubator, medical compressed air is also required.
2. As a power source or gas source for medical equipment:
   • surgical instruments: Such as scalpel, suture gun, etc., medical compressed air is needed to dry the wound to facilitate suture, or to control its working speed and strength.
   • attractor: Use medical compressed air to create negative pressure and extract the secretion in the body.
   • steam sterilizer: Provide stable steam pressure to ensure high temperature steam sterilization effect.
   • Dental Equipment: Used for oral hygiene cleaning and care, drive dental pneumatic drill and other pipeline purging system.

3. Quality Requirements and Standards

the quality requirements of medical compressed air are very strict, mainly including the following aspects:

1. cleanliness requirements: Bacteria, oil fume, moisture and peculiar smell in the air must be filtered. The total number of bacteria and actinomycetes should be less than 100cfu/m & sup3;, and the oil content should be less than 0.1 mg/m & sup3;.
2. Stability requirements: The flow and pressure must be stable, and there must be no sudden changes to ensure the normal operation and treatment effect of medical equipment.
3. Physical parameter requirements: The temperature should be kept between 5 ℃-40 ℃, and the humidity should be kept between 25%-75%.

In addition, the production and supply of medical compressed air must also comply with relevant industry standards, such as ISO 7396-1 "Requirements for the design and installation verification of air and oxygen pipeline systems in medical institutions" and ISO 13485 "Medical devices-Quality management system requirements.

4. Production and Supply

medical compressed air is usually produced by medical air compressors on the hospital site. These compressors must meet relevant national safety standards and can provide stable and sterile compressed air. In the production process, it is also necessary to equip the corresponding filtration and drying equipment to ensure the cleanliness and stability of the compressed air. At the same time, hospitals and medical institutions also need to regularly carry out quality inspection and maintenance of medical compressed air to ensure that it always meets the requirements of use.

5. Summary

as one of the indispensable substances in medicine, the quality of medical compressed air is directly related to the effect of medical equipment and treatment effect. Therefore, in the process of production, supply and use, it is necessary to strictly comply with relevant standards and requirements to ensure the quality and safety of medical compressed air. With the continuous development and progress of medical technology, the application of medical compressed air in the medical field will become more and more extensive and important.
