Abstract: An inflation device includes a syringe body containing a bore. The bore holds a fluid that is used to inflate a separate device such as a dilation balloon. A plunger assembly slides within the syringe bore and contains a sealing member that forms a fluid tight seal with the syringe body. A shut-off valve is disposed within the distal end of the syringe body. The distal end of the syringe body has a fluid bypass channel fluidically coupled to the aperture of a connector. The shut-off valve has a spring-biased moveable piston with a bypass lumen contained therein, wherein the bypass lumen forms a fluid path between the bore and the fluid bypass channel when the pressure of the fluid is below a threshold value. The fluid path between the bore and the fluid bypass channel is interrupted when the pressure of the fluid is above the threshold value.

Abstract translation: 膨胀装置包括包含孔的注射器主体。 孔保持用于使诸如扩张气囊的单独装置膨胀的流体。 柱塞组件在注射器孔内滑动并且包含与注射器主体形成流体密封的密封构件。 截止阀设置在注射器主体的远端内。 注射器主体的远端具有流体连接到连接器的孔的流体旁路通道。 截止阀具有弹簧偏压的可移动活塞，其中容纳有旁路腔，其中当流体的压力低于阈值时，旁路内腔在孔和流体旁路通道之间形成流体路径。 当流体的压力高于阈值时，孔和流体旁路通道之间的流体路径被中断。
