Abstract: A gas cylinder monitoring system is disclosed having a gas cylinder for receiving and distributing gas contained therein, a first monitoring system associated with the gas cylinder operable to monitor data associated with the gas cylinder and having a transmitter operable to broadcast the data at a controlled time and/or time interval in a discrete advertisement package, and a second monitoring system associated with one or more locations in which the first monitoring system may reside and having a receiver operable in a first mode to receive the advertisement package broadcast from the first monitoring system when the second monitoring system is within range of the first monitoring system.

Abstract: There is provided an apparatus for detecting the deteriorating health of a patient receiving gas from a respiratory device. The apparatus comprises a sensor unit configured to monitor a flow rate or pressure of a gas that is flowing in a pipe that connects the respiratory device to a gas delivery device worn by the patient, and a processor configured to measure a respiratory rate of the patient based on variations in the flow rate or pressure of gas in the pipe and to implement a trend analysis of the measured respiratory rate. The processor is configured to generate a warning when it determines that there is an upward trend in the measured respiratory rate and that a magnitude of the trend exceeds a threshold.

Abstract: The present invention provides a monitoring apparatus for an outlet of a vessel storing gas under pressure. The monitoring apparatus comprises a flow control valve movable to a position between a fully open position and a fully closed position to adjust a flow of gas from the outlet of the vessel, a valve position detector connected to the flow control valve to detect the position of the flow control valve, an internal pressure sensor to sense an internal pressure Pint(t) of the gas in the vessel at different times, a processor, a memory and an alarm. The processor calculates an actual rate of change in pressure dPint/dt of the gas in the vessel over time, and compares dPint/dt with an expected rate of change.

Abstract: The present invention provides a control system (10) for managing the supply of bottled gas to users (12), the system comprising: a gas cylinder system (14) having a gas cylinder (15) for receiving and distributing gas contained therein; a first electronic monitoring system (16) associated with said gas cylinder system (14) and operable to monitor parameters associated with said cylinder system (14); a second monitoring system (18) associated with one or more locations (A-F) in which said cylinder may reside and being operable to monitor the presence or absence of said cylinder within said one or more locations (A-F); and a computer system (20) in communication with each of said second monitors (18) for receiving information therefrom relating to the presence or absence of said cylinder system (14) in said one or more locations (A-F).

Abstract: A gas cylinder monitoring device (34) for use with a valve (18) for controlling the flow of gas from a cylinder (14). The valve (18) has a valve body (20), and the device comprises an ambient temperature sensor (38) to measure the ambient temperature (TA), a valve body temperature sensor (36) to measure the temperature (TV) of the valve body, and a processor (42). The processor (42) operates to process a compensated temperature (CT) calculated from the difference between the measured valve body temperature (TV) and the ambient temperature (TA) over time (t). A flow-rate (FR) of the flow of gas from the cylinder and/or the pressure (P) on the gas is determined.

Abstract: A gas cylinder monitoring system (10) for monitoring the contents of a gas cylinder in an EMS vehicle (50) including a gas cylinder (12) for receiving and distributing gas therein, an individual cylinder monitoring system (14) operable to monitor data associated with the gas cylinder (12) and having a cylinder monitoring transmitter (16) operable to broadcast the data, and at least one receiving station (60,70) having a receiver (18,20) operable to receive the data from the individual cylinder monitoring system (14) and indicate if the contents of the gas cylinder (12) are below a pre-determined threshold and require replacing.

Abstract: The present invention provides a gas cylinder system (14) having a gas cylinder (15), a first electronic monitoring system (16) operable to monitor cylinder specific data (CSD) associated with said cylinder (15) or a patient specific data (PSD) associated with a patient. Such a cylinder system (14) may be used in a number of ways such as to modify the delivery of gas to a patient.
