Fill port adapter for medical gas cylinder valves

Abstract

The present invention allows an additional connection to a standard medical gas cylinder valve such as a CGA-870 valve. An additional connection may be used for filling a cylinder without removing the pressure reducer, simultaneous filling while drawing through the pressure reducer, or for any other purpose that requires an additional or non-standard connection to the cylinder. The additional connection will be through an adapter that screws into the burst disc port. Some gas cylinder valves have the burst disc center line closer to the outlet centerline. This close centerline may be accommodated by offsetting the access of the first and second port to provide clearances required.
