In the early days of our country, hospitals used oxygen cylinders and oxygen bags to deliver oxygen to patients. While with the advancement of gas separation technology, more and more hospitals began to build their own oxygen systems. This is mainly because medical oxygen concentrators have many advantages that cannot be replaced by oxygen supply from oxygen cylinders.

Cylinders for medical oxygen are filled at 160 bars. If not handled properly, a leak may occur and cause a hazard. The upfront cost of medical oxygen cylinders is lower. Fluctuations in costs and increased overtime make it more costly and uncertain. Oxygen is sealed in cylinders, and the hospital cannot measure the purity of the oxygen in the cylinders on-site. Most small hospitals do not have mechanisms to measure and monitor purity and pressure, so there is a risk of substandard oxygen in the bottle. There is often residual gas when the cylinder is refilled. This results in gas loss. The "conversion loss" of an oxygen cylinder can be as high as 10%. If the hospital's demand for oxygen is lower than expected, there will be storage costs for the cylinders.

Hospitals need at least 2-3 people in 3 shifts to manage the uncertainty and delays in the supply of these cylinders, which could create new problems.

Once an oxygen concentrator is set up and connected properly, it is relatively safe. There needs to be an upfront investment cost, and generally speaking, hospitals can get a return on investment within 1-2 years. For medical oxygen generators, the hospital's later costs are mainly spent on electricity and maintenance. Compared with gas cylinders, hospitals can achieve greater savings. The medical oxygen system provides medical oxygen with an oxygen concentration of 93±3%. The user can regularly check the oxygen purity and pressure according to the corresponding device on the oxygen generator equipment. There is no major loss or waste for the use of oxygen. The oxygen generator can produce oxygen as required, and enter standby mode when the oxygen supply is sufficient. Save energy and use equipment efficiently. There is no need for manpower to handle the generator. It can avoid human error operation and increase the security and stability of the system.
