Abstract
A gas sensor module is coupled to a medical gas system in a healthcare facility to monitor gas type and/or gas flow. In some embodiments, the gas sensor module is coupled to a gas pipe of the medical gas system behind a wall, ceiling, floor, access panel, or the like and transmits an alarm signal to an alarm controller located elsewhere in the healthcare facility. In other embodiments, the gas sensor module plugs into a service outlet of the medical gas system. Also disclosed is a combination service outlet and gas sensor module. A main gas alarm module may communicate with one or more remote gas alarm modules.

29. An apparatus for monitoring a gas extant in a gas pipe of a healthcare facility, the apparatus comprising
a housing; -
a sensor carried by the housing and coupled pneumatically to the gas pipe, the sensor producing a sensor signal indicative of the type of gas extant in the gas pipe; and
a circuit carried by the housing and coupled electrically to the sensor, the circuit processing the sensor signal and producing an alarm signal if the gas extant in the gas pipe is an improper type of gas.

32. An apparatus for dispensing to healthcare equipment a gas from a gas pipe of a medical gas system of a healthcare facility and for monitoring the gas dispensed, the apparatus comprising
a gas sensor, a circuit coupled to the gas sensor, a housing carrying the circuit and the gas sensor, the housing being coupled to the gas pipe, the housing being configured for coupling of healthcare equipment thereto to receive gas from the gas pipe that passes through the housing, a sample of the gas from the gas pipe being diverted to the gas sensor so that the circuit is able to monitor the type of gas diverted to the gas sensor.
-
33. A gas sensor module that is adapted to be coupled to a line of a medical gas system that is designated for delivery of a type of gas, the gas sensor module being adapted to monitor the type of gas flowing through the line, to determine whether the type of gas flowing through the line is the proper gas type, and to generate an alarm signal if the gas type is improper.
-
34. A gas alert for a medical gas system, the gas alert comprising
a main gas alarm module coupleable to a line adjacent a bulk supply of medical gas in a healthcare facility, the main gas alarm being adapted to sense whether the type of gas flowing through the line is the proper gas type, and at least one remote gas alarm module that is located remotely from the main gas alarm module and that receives communications from the main gas alarm module indicative of an alarm condition sensed by the main gas alarm module.
