Abstract: There is disclosed a telemetry monitoring apparatus for remotely monitoring a plurality of users, such as firefighters, working in a hazardous environment. The apparatus comprises a plurality of portable devices, each arranged to be associated with breathing apparatus worn by a user, and at least one central monitoring station onto which portable devices can be logged on and monitored. The portable devices are arranged to transmit a logon message including an identifier identifying either the user or the portable device.

Abstract: There is disclosed a fluid adapter for a breathable gas delivery device, such as a facemask, for delivering breathable gas to a user. The fluid adapter comprises an adapter body defining an adapter chamber; a pressurized gas inlet port in fluid communication with the adapter chamber and arranged to be fluidically coupled to a source of pressurized breathable gas and an ambient air inlet port arranged to provide fluid communication between the adapter chamber and ambient air outside of the fluid adapter. The adapter also comprises an adapter outlet port in fluid communication with the adapter chamber and arranged to be fluidically coupled to a delivery device gas inlet port of the breathable gas delivery device; and an adapter connector arranged to connect the fluid adapter to the breathable gas delivery device such that the adapter outlet port is fluidically coupled to the delivery device gas inlet port.

Abstract: A monitoring apparatus for monitoring a wearer of a breathing apparatus including a source of breathable gas which is supplied to a delivery device via a fluid line, the monitoring apparatus including a breathing detector arranged to determine if breathing using the breathing apparatus has commenced, and a mobile monitoring device arranged to be associated with the wearer and which can be activated to monitor the motion of the wearer. The monitoring apparatus is arranged to activate the mobile monitoring device when it is determined that breathing has commenced.

Abstract: A temperature control garment arranged to be worn on a user's torso including a bladder defining a chamber for receiving a supply of gas, the bladder including a back portion which is arranged to overlie at least a portion of a user's back. An arrangement of holes is provided in the bladder for directing gas supplied to the chamber towards the user's body so as to modify the temperature of the user's body. The garment also includes a breathing duct coupled to the bladder for receiving a supply of gas, the breathing duct having at least one duct outlet for delivering the gas supplied to the breathing duct to the user.

Abstract: A closed circuit breathing apparatus (2) and a method of operating the same, the method comprising: determining whether a sufficient amount of replenishing gas is being supplied to a breathing circuit (4); sensing pressure within the breathing circuit (4) using a pressure sensor (6); generating a pressure signal representative of the sensed pressure; determining whether the pressure signal is representative of breathing; and generating an alert if it is determined that both an insufficient amount of replenishing gas, such as oxygen, is being supplied to the breathing circuit (4) and that the pressure signal is representative of breathing.

Abstract: There is disclosed a lung demand valve comprising: a body within which is disposed a diaphragm and a valve assembly having a valve inlet, the valve assembly and diaphragm arranged to cooperate to control the delivery of breathable gas to a user. There is also provided a breathable gas inlet fluidically connected to the valve inlet inside the body and arranged to be fluidically connected to a supply of breathable gas; and a whistle coupled to the body. The whistle has a whistle inlet fluidically connected to the breathable gas inlet inside the body and a whistle outlet disposed outside the body. In use, when the pressure of the breathable gas in the breathable gas inlet is less than a threshold, breathable gas flows from the breathable gas inlet through the whistle inlet and outlet thereby causing the whistle to sound outside of the body.

Abstract: There is disclosed a telemetry monitoring system including a central monitoring unit configured to display data regarding one or more portable devices, each associated with the breathing apparatus of a user. The system further includes removable data storage connected to the central monitoring unit and configured to store system status data of the central monitoring unit as recovery data, the system status data defining an operational status of the central monitoring unit. In the event of a failure of the telemetry monitoring system, the telemetry monitoring system can be recovered by restoring the recovery data to the central monitoring unit or a replacement central monitoring unit from the removable data storage.
