Hospital-grade oxygen system: the "invisible heart" behind life support

Every oxygen intake in the ICU and every breath in the operating room cannot be separated from the precise operation of the hospital level oxygen production system. It is like an invisible guardian of life, transforming ordinary air into life-saving 'golden gas'. Today's Headlines Exclusive Reveals - How Modern Hospitals Win the 'Battle of Hypoxia' with This System!

1、 Core position: Revolution from steel cylinder transportation to "oxygen water pipe"

The evolutionary history of the speed of life and death
The era of steel cylinders (before the 1980s): Industrial oxygen was the main source, containing impurities such as carbon monoxide and dust. Inhalation by patients could easily cause coughing and even pulmonary edema.

The era of centralized oxygen supply (1983 present): China's first central oxygen supply system was born, with oxygen delivered directly to the ward through pipelines, bidding farewell to the physical exertion of carrying steel cylinders upstairs, and increasing oxygen supply efficiency by 300%.
In the era of intelligence (starting from 2020s): PSA oxygen concentrator+IoT monitoring, achieving "on-demand distribution" of oxygen with an error rate of less than 0.1%.

Modern hospitals come standard with three major systems:
Central oxygen supply system: delivering ≥ 90% pure oxygen;
Central suction system: negative pressure suction of sputum and surgical waste liquid;
Compressed air system: drives ventilators and anesthesia machines.
Data perspective: The daily oxygen consumption of tertiary hospitals exceeds 5000 cubic meters, equivalent to filling two standard swimming pools!

2、 Core technology: how to "extract" essence of air from PSA oxygen generator

Four step separation technique: transformation from air to medical oxygen

Molecular sieve sniper battle: Nitrogen molecules (3.64 Å) are captured by zeolite micropores, while oxygen molecules (3.46 Å) penetrate and output.
Aseptic defense line: The sterilization membrane intercepts 99.99% of bacteria, preventing respiratory infections.
• Safety redundancy design: Triple insurance without oxygen interruption

3、 Efficiency showdown: Why does PSA oxygen concentrator crush liquid oxygen/steel cylinders?

Economy: Purchase cost
PSA oxygen generator: consumes only about 1.2 yuan/m ³ of electricity;
Liquid oxygen system: The purchase cost is 3.2 yuan/m ³, and daily operation and maintenance management requires certification to work;
Gas cylinder oxygen (40L): unit price around 25 yuan/bottle (Changsha), utilization rate is only 70% (waste of residual pressure).
Note: Actual market prices may vary based on price limits for specific procurement projects.

4、 Clinical battlefield: life span from ICU to high-altitude outpost

Intensive Care Unit (ICU)
ECMO oxygen supply: The oxygen production system provides 99.5% pure oxygen to the extracorporeal membrane lungs, reducing the risk of blood infections;
Premature infant incubator: Moist constant temperature oxygen (33 ℃± 1 ℃, humidity 60%) protects the alveoli of newborns.

High altitude emergency treatment
At an altitude of 5000 meters, the post is equipped with a PSA oxygen concentrator that is resistant to low-pressure environments, and the oxygen concentration still reaches 90% (ordinary equipment only has 70%);
Mobile makeshift hospital: Vehicle mounted oxygen system provides 30 minutes of oxygen supply, saving 100 people in the Wenchuan earthquake.

Operating Room 'Oxygen Storm'

• Open chest surgery: instantaneous oxygen demand reaches 100L/min, with dual supply of liquid oxygen storage tank and PSA;
Laser surgery: High purity oxygen assisted laser knife, with an error of less than 0.5%, can avoid tissue burns.

The hospital level oxygen production system is a precise dance between cryogenic methods and molecular sieves, and a silent dialogue between the Internet of Things and life. It uses a triple oxygen source to establish a safety bottom line and isolates death threats with a 0.22 μ m filter. Remember three numbers:
90% - medical oxygen concentration baseline;
8 atm - safe pressure ceiling;
0.1 seconds - fault response speed.
