Medical gas faults rectified fast

Medical gas system supplier to the NHS SHJ Hospital Pipelines has developed two “unique” HTM02-01-compliant remote monitoring and control systems for medical gas pipeline systems.

Able to operate alongside existing alarm panels, the Evolution system takes information from the main hospital medical gas alarm control panel and “performs sophisticated” telemetry back to SHJ. The corresponding control system, Empower, also feeds information through.

Until now SHJ says each hospital’s medical gas Approved Person (AP) had to be informed by a switchboard operator or other individual monitoring alarm panels if an alarm had been triggered, before stopping what they were doing, investigating, and dealing with the alarm appropriately. Now they can not only be informed that an alarm has been triggered, and if the incident requires an engineer, but will also receive confirmation that one is on their way.

Empower controls the plant that is connected to, while its built-in software also monitors the plant environment and alarm history. Should a unit run beyond set parameters, the system automatically switches to the back-up plant, notifying the duty engineer accordingly. Any faulty part will be identified to SHJ’s on-call engineer, who can then bring the correct spare, immediately, or on his next visit.

Both Evolution and Empower comprise a touch screen monitor with Uninterruptible Power Supply (UPS), and communications back both to SHJ and the user hospital’s estates department. In recent London hospital trials it took just two minutes from an alarm being noticed to a call being received by an engineer, acknowledgement of a fault, and the engineer being en-route.
