Disposable manometer for use with a CPR bag |
摘要 |
A disposable manometer includes a chamber connectable to a source of CPR air pressure via a patient breathing valve and an elongated restricted passageway. The manometer includes a dial and a pointer rotatably disposed with respect to the dial to indicate the pressure sensed within a manometer chamber. The pointer has an actuator stem with a spiral-shaped protrusion coupled to a groove within an opening of a stem coupling attached at the center of a diaphragm forming one wall of the manometer chamber. Responsive to pressurized air entering the manometer chamber, the diaphragm reciprocates against the force of a biasing spring moving the stem coupling with respect to the actuator stem for the pointer so that the interaction between the spiral-shaped protrusion and the groove causes rotation of the pointer to indicate the pressure within the manometer chamber. The disposable manometer is intended to be used with a CPR bag or a patient breathing tube. |
