Medical Gas Pressure Alarm
In the medical gas system, a three-level gas monitoring alarm system is generally installed. Their function is to provide equipment managers and medical staff with the status parameters (pressure, flow, etc.) of the medical gas system in real time. Once the parameters exceed the normal range, they will send out sound and light alarm signals.
Thefirst level is the gas station monitoring and alarm system, which is installed in the gas station to monitor the working conditions of the gas source, gas processing equipment and storage equipment. It consists of electric contact pressure gauges installed on high and low pressure gas pipelines or gas tanks, flow meters installed on gas pipelines, control alarm devices installed in the control box and alarm circuits.
When the gas station is working, the manager can check the operation of the gas station equipment at any time through the pressure gauge and flow meter. Once the gas in the pipeline or gas tank is over or under pressure, the red light on the control box will be on and the buzzer will sound to remind the management staff to pay attention.
The second level is the floor monitoring alarm system, which is installed on the floor where the gas is used to monitor the air supply status of the air supply main pipe to the floor. It is composed of an electric contact pressure gauge installed on the meter valve box of the gas alarm device on the raft, a flow meter installed on the floor gas main pipe, a control alarm device and an alarm circuit installed on the meter valve box of the alarm device or the nurse station. The medical and maintenance personnel on this floor can check the gas condition in the floor gas main pipe at any time through pressure gauges and flow meters. Once the gas in the pipeline is over or under pressure, the red light on the control alarm device will be on and the buzzer will sound to remind the relevant personnel to alarm.
