The central oxygen supply system concentrates the oxygen source in one place, and the high-pressure oxygen from the source is depressurized and transported to various gas terminals through pipelines. There are quick plugging sealed sockets at each gas terminal, and gas equipment (such as oxygen humidifiers, ventilators, etc.) can be plugged in to supply gas.

working principle

The central oxygen supply system is mainly used for oxygen supply in hospital wards, emergency rooms, observation rooms, and operating rooms.

main components

The central oxygen supply system consists of gas source, control device, oxygen supply pipeline, oxygen terminal, and alarm device.

The gas source can be liquid oxygen or high-pressure oxygen cylinders. When the gas source is a high-pressure oxygen cylinder, 2-20 oxygen cylinders can be selected according to the gas needs. The oxygen cylinders are divided into two groups, one for oxygen supply and the other for backup.

The control device includes a gas source switching device, a pressure reducing and stabilizing device, and corresponding valves, pressure gauges, etc.

Oxygen supply pipeline is used to transport oxygen from the outlet of the control device to various oxygen consuming terminals.

Oxygen terminals are located in wards, operating rooms, and other oxygen consuming departments. When installing a quick plug sealed socket on the oxygen terminal, the connector of the oxygen supply equipment (oxygen humidifier, ventilator, etc.) can be inserted into the socket to supply oxygen and seal it; When not in use, you can unplug the oxygen supply device connector or close the manual valve.

According to the different needs of hospitals, oxygen terminals also have different structural forms. Generally installed on the wall, there are two types: concealed installation (embedded inside the wall) and exposed installation (protruding outside the wall and covered with decorative covers); There are several forms of terminals for operating rooms and other wards, such as wall mounted and mobile.

The alarm device is installed in other locations such as the control room and duty room. When the oxygen supply pressure exceeds the upper and lower limits of the operating pressure, the alarm device can emit sound and light alarm signals to remind relevant personnel to take corresponding measures.
