Centralized Oxygen Supply System in Hospital

Components:
Centralized oxygen supply system consists of gas source, control device, oxygen supply pipe, oxygen terminal and alarm device and so forth.

1. Gas Source Gas source can be liquid oxygen and high pressure oxygen bottle too. When gas source is high pressure oxygen bottle, it has to select 2～20 oxygen bottles according to the demand. Oxygen bottle can be divided into two groups, one group for supplying oxygen, the other group for standby.
2 Control Device Control device includes gas source switch device, pressure-reducing device, pressure regulator, relative valve and meters.
3. Oxygen Supply Pipe Oxygen supply pipe means to transport oxygen from control device to oxygen terminal.
4. Oxygen Terminal Oxygen terminal is equipped in patient room, operation room and other departments that need oxygen. Install rapid plug-in airproof socket in oxygen terminal. It only needs to plug tie-in of oxygen equipment (oxygen humidifier, ventilator, etc.) into the socket, then it is able to supply oxygen and ensure airproof. When it is not needed, take the tie-in out, otherwise, close manual valve.
5. There are various structures according to different hospitals’ requirements on oxygen terminal. Generally, there are two kinds, hidden installation (embedded inside of wall) and obvious installation (on the wall, cover by decoration). Moreover, there are wall mounted, mobile and overhead model in operation room and other patient terminal. Alarm Device Alarm device can be installed in control room, duty room or other designated places. When oxygen pressure exceeds lower and upper limits, the alarm device will generate sound, light alarm signal to remind relative personnel to adopt related measures.

Main Technical Parameters:
(01)Oxygen traffic Q peak: 24~40 m 3 /h 20 bottle ~70 bottle /day
(02)End Output Pressure: 0.3~0.5Mpa (increase pressure according to customers’ requirements)
(03)This system is able to lead termimal quantity: 10 ~1000 (max traffic of each terminal >15L/min)
(04)Average leaking rate per hour of system pipe path >0.15% (national standard >0.5%)
(05)Bottle unit switch automatically, can be connected with liquid oxygen jar.
(06)Adopt plug-in self-sealing rapid tie-in in terminal, convenient for using.
(07)Bus cylinder can switch manually or automatically, and can be connected with liquid oxygen jar or oxygen producer. It is able to lead less than 1000 terminals.

Main Characteristics:
◎ Oxygen supply mode in oxygen station can select one of three modes, medical oxygen producer, liquid oxygen storing jar and bus for supplying oxygen or two of them.
◎ Oxygen bus system equipped with sound and light alarm device for lack of oxygen pressure, realize oxygen supply automatically or manually.
◎ Adopt double path design in oxygen pressure regulator box to guarantee continuity of oxygen supply for each patient area.
◎ Each patient nurse station equipped with one supervising meter to monitor oxygen supply pressure and quantity for each patient area automatically. It offer reliable basis for cost account for the hospital.
◎ Adopt anaerobic copper, which is under degreased, or stainless steel pipe in oxygen supply path. Besides, it adopts special goods for oxygen in all connecting accessories.
