Problems solved by technology

It is therefore more difficult to produce short messages of the type required for medical gas alarms in such languages ​​because of the much greater complexity and memory requirements to reproduce as visual output in such languages ​​than in English alphabet languages
[0018] Finally, many current annunciators are inefficient in the way they can handle input and output signals, including routing one input signal from a pressure sensor through multiple relay outputs, multiple signal inputs from a source device to Single relay output, or a combination of these functions

Embodiment Construction

[0041] figure 1 is a front view of an alarm panel according to one embodiment of the present invention. The alarm panel is indicated generally at 30 and includes a housing 31 and a display 32 . A number of additional indicators such as LEDs 33 are located near the display 32 for supplementary purposes. Details regarding display 32 and its relationship to and use of other elements will be discussed with reference to other figures, and reference to figure 1 , the display 32 has been preprogrammed to show the monitored location, the identification of the two medical gases (and the medical vacuum), the relative status of these gases ("low"), the actual pressure of the gas and the status of the vacuum. The rest of the display provides a text message that the gas is in good condition and repeats the identification of the zone and thus the panel. The manner in which the warning system provides these indicia and information will be discussed with reference to some of the other figu...

Abstract

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.

Description

technical field [0001] The present invention relates to medical gas systems, and in particular to medical gas alarms and related instruments. Background technique [0002] In a modern medical environment, a variety of gases are directed from sources to desired locations and thereafter used for various purposes. These gases usually include oxygen (O 2 ), nitrogen (N 2 ), nitrogen dioxide (NO 2 ) and medical air, collectively referred to as Piped Medical Gas and Vacuum Systems or "PMGVS". Such a system also has the function of vacuuming where necessary at a specific location, but driven from a central location. [0003] For convenience, the term "hospital" is used here, but it should be understood that related needs and specific issues apply to medical facilities other than hospitals, such as, but not limited to, urgent care centers and specialized surgical facilities. [0004] However, PMGVs are generally maintained in one or more (figuratively) central locations or "ban...
