Abstract

A syringe having an internal pressure gauge comprises a syringe barrel; a piston within the barrel; a spring coupled to the piston at a first position of the spring, the spring having a second portion that is movable in response to fluid pressure within a syringe cavity; and a pressure gauge having an indicator correlated to a plurality of positions of the second portion of the spring to indicate a pressure of a fluid. The spring can be a bellows. The fluid chamber can be in fluid communication with a cuff of an inflatable medical device, such as an endotracheal tube, such that the measured pressure comprises the fluid pressure within the cuff.
