Abstract:
A manometer for measuring the hydrodynamic pressure of fluids parenterally administered to a patient, said manometer comprising:a housing having a fluid inlet and a fluid outlet; a continuously open passage formed in said housing, said passage accommodating continuous flow of fluid therethrough from said fluid inlet to said fluid outlet; a pressure-measuring chamber formed in said housing, one end of said pressure-measuring chamber being in fluid communication with said passage, said pressure-measuring chamber having at the other end thereof a normally closed air space that defines a non-expansible volume; a space-saving chamber formed in said housing, one end of said space-saving chamber being in air communication with said pressure-measuring chamber, said space-saving chamber having at the other end thereof a normally closed air space that defines a non-expansible volume; and indicia associated with said pressure-measuring chamber, for indicating the pressure of the fluid flowing through said passage.
