Abstract
An assembly structured to inflate a retaining or pressure cuff associated with an artificial airway tube such as an endotracheal and/or tracheotomy tube and concurrently monitor pressure therein including a casing having an interior pressure chamber. A pump assembly is movably connected to the casing and structured to force fluid flow to the retaining cuff through said pressure chamber. An indicator member is disposed within the casing, is visually accessible through casing window, and is variably positionable dependent on and indicative of existing pressure within the retaining cuff. The existing pressure within the pressure chamber is substantially equivalent to that within the retaining cuff thereby facilitating the variable position of the indicator member to indicate pressure within the cuff. A junction is disposed between the casing and an inflation lumen to the restraining cuff and is structured to allow disconnection between the casing and the lumen but prevent reconnection thereto.
