Each Hospital room normally has an oxygen supply with pressure and flow regulation. This entry uses the available oxygen system and 120VAC power supply in the room. The primary components of the entry are: a pneumatic valve, a short cycle timer, a Bendix QR-1 type air brake quick release valve, a water column, an orifice(fixed/adjustable) where required plus lines and fittings to connect the parts. This is low tech and most parts are already available in quantities of 100,000 or more. It is simple to assemble and should have a life above a million cycles. Three basic configurations are shown for flexibility of design/available components.

    I am a practical person and build/design things out of common components and sometimes make adapters to enable non-conventional uses of items in a system. CAD for me is "Cardboard Aided Design". Maintenance/ Maintainability are considerations in build/use/buy - I believe in forethought as opposed to afterthought - Wish everybody got it right the first time!
