Why are more and more newly built hospitals choosing oxygen generators over liquid oxygen or cylinder oxygen?

The core reason why newly built hospitals prefer oxygen generators over liquid oxygen or cylinder oxygen is that the comprehensive advantages of oxygen generators in terms of safety and economic value better meet the operational needs of modern hospitals.

Hospitals have extremely high requirements for the safety of oxygen supply. Compared with traditional oxygen supply methods (liquid oxygen, cylinder oxygen), oxygen generators have a greater advantage in risk control:

1. Eliminating High-Risk Storage and Transportation Risks

   Liquid oxygen needs to be stored at a low temperature of -183℃. The storage tank is a high-pressure container, which poses a risk of freezing damage, tank leakage, and even explosion. Cylinder oxygen is a high-pressure gas. If there is a collision or valve damage during transportation and handling, it may cause gas leakage or explosion.

   Oxygen generators:These devices directly generate oxygen from the air (using molecular sieves to separate oxygen from the air), eliminating the need for storing liquid or compressed oxygen. This avoids the safety risks associated with high-pressure containers and cryogenic storage, and also reduces the probability of accidents during transportation (such as collisions with cylinders or leaks from liquid oxygen tanks).

2. Reduced Risk of Human Error:

   Liquid oxygen and cylinder oxygen require regular replacement or replenishment, relying on manual operation (such as cylinder handling and pipe connections). Improper operation (such as loose connections or valves not being closed tightly) can lead to oxygen leaks. Oxygen is a combustible gas, and leaks can easily ignite upon contact with a source of ignition.

   Oxygen generators can operate fully automatically, connecting directly to the ward terminal via pipeline. This eliminates the need for frequent manual intervention, reducing safety hazards caused by operational errors. They are particularly suitable for situations with limited staff, such as at night or in emergency rooms.

3. Stable Oxygen Supply, Avoiding Supply Interruption Risks:

   Liquid or cylinder oxygen may experience temporary supply interruptions due to transportation delays or insufficient inventory. Hospital intensive care units (ICUs) and operating rooms have extremely high continuous oxygen requirements, and supply interruptions could endanger patients' lives.

   Oxygen generators can continuously produce oxygen as long as they are powered on and have air input. With backup power (such as a generator), they can guarantee basic oxygen supply in case of power outages or other emergencies, offering far greater stability than traditional methods that rely on external supplies.

Considering both short-term investment and long-term operation, the economic advantages of oxygen generators are becoming increasingly apparent, making them particularly suitable for the long-term planning of newly built hospitals:

1. Lower Long-Term Costs than Traditional Methods

   The costs of liquid oxygen and cylinder oxygen include "the gas itself + transportation + storage equipment maintenance": Liquid oxygen requires regular purchases, with unit prices fluctuating with the market (affected by energy and transportation costs), and storage tanks require regular inspection and maintenance; cylinder oxygen requires cylinder rental fees and handling costs, resulting in higher long-term accumulated costs.

   The cost of an oxygen generator is primarily a "one-time equipment investment," with subsequent costs only including electricity (operating at typically lower power) and regular replacement of consumables such as filters and molecular sieves. The total cost over the long term (generally, equipment lifespan is over 10 years) is far lower than the continuous purchase of liquid oxygen or cylinder oxygen. For example, a medium-sized hospital using oxygen generators can typically recoup its investment in 5-8 years, after which costs are significantly lower than traditional methods.

2. Saves Space and Labor Costs:

   Liquid oxygen storage tanks and cylinder oxygen storage areas require dedicated space (away from fire sources and meeting safety distances). New hospitals choosing traditional methods need to plan additional storage space, increasing land or building costs. Oxygen generators, on the other hand, have a smaller footprint (mostly modular devices) and can be installed on the equipment floor or in a dedicated machine room, saving space.

   Traditional oxygen supply methods require dedicated personnel to purchase, transport, and replace cylinders/liquid oxygen, with labor costs increasing with the hospital's size. Oxygen generators only require periodic maintenance (such as monthly consumable checks), significantly reducing labor input.

3. Flexible Expansion Adaptable to Hospital Size:

   New hospitals may gradually increase their bed capacity. Oxygen generators can be flexibly expanded through modular design (such as adding oxygen generating units) without large-scale modifications. In contrast, increasing the supply of liquid oxygen or cylinder oxygen requires replacing storage tanks with larger ones or increasing the purchase of cylinders, resulting in higher adjustment costs.

   For small medical institutions such as branch hospitals and community health centers, the initial investment in small-scale oxygen generators is controllable, avoiding the problem of "high cost for small usage" associated with traditional methods (such as the higher unit price of small-batch purchases of cylinder oxygen).

In summary, oxygen generators are more stable and have lower risks in terms of safety, offer better long-term economic benefits, and are well-suited to the intelligent and intensive operation needs of modern hospitals, thus becoming the mainstream choice for newly built hospitals. However, the initial investment in oxygen generators is relatively high, making them more suitable for newly built hospitals with long-term plans; for medical institutions with short-term use and very small scale, traditional methods may still have some applicability.
