Patent ID: 8360058

Claim:
A system for administering nitrous oxide comprising: an adjustable post mechanism attached to a mounting plate assembly which is attached to a lower portion of a patient chair, said adjustable post mechanism configured for height adjustment and pivotal adjustment; a mounting surface structure having a top surface and a bottom surface, said bottom surface of said mounting surface structure attached to the adjustable post mechanism, said mounting surface structure positioned along a horizontal axis; a fluid control system for controlling the flow of nitrous oxide and oxygen attached to the mounting surface structure, said fluid control system including a fluid meter display mounted on a top surface of said fluid control system, said fluid meter display positioned along a vertical axis at less than 90 degrees relative to the mounting surface structure; a nasal delivery interface system fluidly connected to the fluid control system, said nasal delivery interface system including a single scavenging tube and a single nitrous oxide and oxygen tube fluidly connected to a nasal delivery mask; said fluid control system including a mixed gas output connector fluidly connected to said single nitrous oxide and oxygen tube; a nitrous oxide and oxygen supply fluidly connected to the control system using fluid connectors fixedly attached to bottom surface of said mounting surface structure; a vacuum source fluidly connected to the scavenging tube for scavenging excess gases; and a breather bag mounted to a top surface of the mounting surface structure, said breather bag positioned along a vertical axis about 90 degrees depending upwardly from the mounting surface structure, said breather bag attached rearward of said fluid control system to allow full view of fluid meter display, said breather bag fluidly connected to the control system using an elongated tubular structure.
