What is the role of medical compressed air systems

As a core part of the hospital’s “life support system”, the medical compressed air system runs through the entire diagnosis and treatment process. The specific functions are as follows:

1. Core medical support

1. Respiratory Assisted Therapy

• Ventilator air supply: Provide sterile compressed air for neonatal incubators, anesthesia machines and emergency equipment to ensure accurate control of oxygen concentration.
• atomization treatment: Drive the nebulizer to atomize the medicinal liquid and directly act on the respiratory tract to improve the treatment effect.

2. Surgical power guarantee

• Pneumatic surgical instruments: Drive precision tools such as orthopedic drills and dental air drills to provide stable power output.
• minimally invasive interventional: Provide air supply to the endoscopic pneumoperitoneum machine and establish a surgical operation space.

3. Negative pressure isolation system

• Infectious disease room control: Prevent the leakage of pathogens through negative pressure ventilation, which meets the requirements of the “Technical Specifications for Building Clean Operating Departments of Hospitals”.

2. Treatment and rehabilitation assistance

1. Pneumatic physiotherapy equipment

• antithrombotic therapy: Drive gradient pressure pumps to prevent deep vein thrombosis in long-term bedridden patients.
• Lymphedema management: Promote lymphatic reflux through periodic barometric massage.

2. Hyperbaric chamber support

• Oxygen therapy system: Cooperate with oxygen production equipment to provide high-concentration oxygen for carbon monoxide poisoning, wound healing, etc.

3. Environment and safety

1. Clean space maintenance

• Pneumatic cleaning: Drive the sterile room cleaning equipment to remove dust particles (complying with ISO Class 5 standards).
• Pipeline sterilization: Provide air source for steam sterilizer to ensure the sterility of surgical instruments.

2. laboratory automation

• sample feeding: Quickly transport blood and pathology samples through pneumatic pipes to improve inspection efficiency.
• device driver: Provide controlled gas source for precision instruments such as mass spectrometers and centrifuges.

4. Applications in special medical scenarios

1. cryotherapy

• Liquid nitrogen preparation: Liquid nitrogen is produced by compressed air fractionation for cryosurgery of skin lesions.

2. emergency resuscitation

• Cardiopulmonary resuscitator: Provide power for chest compression to ensure accurate compression depth and frequency.

5. System advantages and standards

1. Five-fold filtration process

• pretreatment: Pre-filter + activated carbon adsorption (to remove oil vapor and peculiar smell).
• deep purification: 0.01μm bacterial filter (filtration efficiency 99.9999%).
• dew point control: Pressure dew point ≤-50℃ to prevent dew condensation in pipes.

2. intelligent monitoring

• real-time monitoring: Pressure, temperature, oil content, and microbial indicators can be traced throughout the entire process.
• early warning mechanism: Automatic alarm in abnormal state, meeting the requirements of Technical Specification for Medical Gas System.

3. redundancy design

• Alternate operation of dual compressors: Ensure 24-hour uninterrupted air supply (in line with GB50736-2012 design standards).
• Emergency gas tank reserve: Meet sudden gas demand (capacity ≥30 minutes maximum consumption).

Through highly integrated air source processing and intelligent monitoring, the medical compressed air system not only ensures the realization of basic medical functions, but also plays a key role in infection control and precision diagnosis and treatment. Its design and operation and maintenance must strictly comply with the “General Hospital Building Design Code” and ISO 13485 Medical Device Certification Standard.
