摘要:
A medical gas alarm systems and associated methods are disclosed. A method of monitoring the medical gas system includes the steps of monitoring a characteristic of a medical gas system using at least one monitoring instrument positioned in a medical gas supply network; generating and sending a particular signal from the monitoring instrument to a CPU when the characteristic measured by the monitoring instrument passes a predetermined threshold; generating a fault signal from the CPU when the CPU determines that a fault condition has occurred; retrieving a stored message from the CPU in response to the fault signal, and in which the stored message other than the fault or threshold condition monitored by the instrument; and sending the stored message from the CPU to an output at a medical gas alarm module.

The invention relates to a device (1) for the redundant provision of a working gas at a gas outlet (3) having a main connection (5) and an alternate connection (7), which are connected to the gas outlet (3), wherein the connection occurs via a common line (9), at least sectionally. Between the main connection (5) and the common line (9), a non-return valve (15) is arranged. The connections are designed to be connected to a main source (19) or to a backup source (21), which provide the same working gas. The device (1) has an adjustable valve, a pressure sensor, and a control unit, preferably designed as one unit in form of a pressure reducer (25), wherein the adjustable valve is arranged between the alternate connection (7) and the common line (9) and is adjusted by the control unit such that the amount of working gas flowing through the alternate connection (7) into the common line (9) is always such that the pressure sensor in the common line (9) does not measure a pressure that is lower than a predetermined working pressure. The invention further relates to a fresh gas mixer, to a system for providing a fresh gas, to a method for the redundant provision of a working gas, and to a method for providing a fresh gas.

Weiterhin sind ein Frischgasmischer, ein System zur Bereitstellung eines Frischgases, ein Verfahren zur redundanten Bereitstellung eines Arbeitsgases sowie ein Verfahren zur Bereitstellung eines Frischgases dargestellt und beschrieben.
摘要:
The compressed gas cylinder (1) is suitable for use in delivering medical gas therapy to ambulatory patients. The compressed gas cylinder (1) has a hollow main body (2) in which therapeutic gas is stored under pressure; a cylinder head (3); a gas outlet (4); and a display (6). The display (6)provides estimates of the time remaining before full depletion of the gas within the cylinder (1). Estimates of the time remaining are based upon estimates of the amount of gas remaining in the gas cylinder (1). However, temperature variation and fluctuations in actual measurements can cause substantial errors when estimating the amount of gas remaining. The improved gas cylinder (1) reduces these errors by calculating time remaining based upon two values for the amount of gas remaining that differ by at least a predetermined minimum.
