ABSTRACT:
Pressure infusion apparatus for controllably pressurizing infusion bags includes a flow-through pressure gauge for indicating the pressures within such infusion bags between minimum and maximum desirable pressures. A lower housing member includes a chamber and an inlet to the chamber for receiving a flow of fluid from suitable sources of pressurized fluid. A resilient member seals the chamber and is used in cooperation with telescoping members in a downstream portion of the gauge for indicating a range of pressures within the chamber from predetermined minimum pressures, below which the gauge will not indicate, and predetermined maximum pressures, above which is dangerous for continuing use of the pressure infusion apparatus. The gauge is adaptable for both use in applications which are axial and transverse with respect to the flow of fluid therethrough.
