    • 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 first portion of the spring can be coupled to the piston to form a sliding seal with an inner wall of the syringe, and the second portion of the spring can move longitudinally within the syringe without sealing contact. The syringe can indicate fluid pressures within a range of at least about 5 to 35 cm H2O, for example. 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. Methods of measuring pressure using a syringe are also disclosed.
    • 具有内部压力表的注射器包括注射器筒; 桶内的活塞; 在弹簧的第一位置处联接到活塞的弹簧,弹簧具有可响应于注射器腔内的流体压力而移动的第二部分; 以及压力表,其具有与弹簧的第二部分的多个位置相关联的指示器,以指示流体的压力。 弹簧可以是波纹管。 弹簧的第一部分可以联接到活塞以与注射器的内壁形成滑动密封,并且弹簧的第二部分可以在注射器内纵向移动而不密封接触。 注射器可以将流体压力表示为例如至少约5至35cm H 2 O的范围内。 流体室可以与诸如气管内管的充气医疗装置的袖带流体连通,使得测量的压力包括袖带内的流体压力。 还公开了使用注射器测量压力的方法。
