Abstract

A multifunction manually oriented inflator to amplify the volume of gas provided for low-pressure inflation of multiple bladders. A default operation can be as a high pressure fixed-volume inflator. A shut off valve preserves excess gas supply while regulated flow allows optimizing volume versus rate of inflation and risk of aspiration. A detachable low-resistance check valve-coupler allows the valve to also serve as an oral inflate and rapid deflate valve for improving volume amplification. Audible alarms distinguish functional inflation from gas wasting over-inflation. Conserved gas can be used to inflate or pressurize additional survival devices or operate signal horns. A locking mount can align and secure a cylinder adjacent the piercing mechanism. Spent cylinder threads can be degraded preventing reinstallation of a micro-pierced cylinder.
