Abstract

Apparatus for regulating pressure in and for controllably pressurizing infusion devices includes a flow-through pressure gauge for indicating and regulating the pressures within such infusion devices between minimum and maximum desirable pressures. Such apparatus includes a gauge, coupled between a fluid source and the bladder portion of the pressure infusion device. The gauge receives pressurized fluid from the fluid source, provides fluid to the bladder, indicates a range of fluid pressures in the bladder and maintains the pressure of fluid in the bladder between minimum and maximum pressures. The gauge includes a telescopingly coupled member to indicate a range of pressures in the bladder. A first valve permits the passage of fluid through the gauge and into the bladder when the fluid pressure exceeds a minimum pressure. A second valve prevents the passage of fluid through the gauge and into the bladder when the fluid pressure exceeds a maximum pressure.
