Description

{Medical Gas Auto Manifold System}

The present invention relates to a gas manifold device, and more particularly, to an automatic manifold device for a medical gas.

Medical gases used in hospitals, nursing homes, etc. have various types such as oxygen, nitrous oxide, carbon dioxide and nitrogen. These medical gases are supplied to each ward, operating room, hospital room, and emergency room in the hospital through piping connected to the central supply unit.

In hospitals, medical gas is always used, and if the supply is interrupted for a while or the pressure drops, it is likely to lead to serious medical accidents involving the patient's life. Therefore, pipelines related to medical gases are required to have high safety so that they can be safely, reliably and continuously supplied.

Conventionally, a large bulk tank is provided and a medical gas is supplied. To this end, a manifold device for distributing and supplying gas is used. However, the conventional manifold device generates an alarm installed in the equipment room, the housekeeping service, and the nursing facility when the gas is exhausted and the pressure drops. Then, the lever located in the left or right side of the collecting device installed in the gas chamber is manually switched. At this time, if the gas of one cylinder is consumed and the lever is used, the gas is supplied within 3 days and the supply is continued.

However, since such a conventional system is operated manually, a danger may occur if gas is dropped at night or on holidays. Further, when the lever for manually switching is malfunctioningly operated or malfunctions, there is a problem that the gas supply is reduced even if there is a large amount of gas. Therefore, research and development of a system for maintaining a stable gas supply is actively proceeding.
