Portable manual ventilation device
First Claim
1. A portable open circuit ventilation device for manually ventilating a patient, comprising:
- an open breathing circuit having a single-shutter valve configured for coupling to a manually squeezable bag, an outflow port, an inflow port, connecting tubing having an interior, said valve, said outflow port and said inflow port coupled by said connecting tubing and in fluid communication in the open breathing circuit; and
a plurality of sensors, said sensors operative for measuring a plurality of parameters within the open breathing circuit, said sensors producing a measurement for a parameter, said sensors coupled to said connecting tubing interior of the open breathing circuit, at least one sensor in fluid communication to the outflow port and at least one sensor in fluid communication to the inflow port, said sensors configured for coupling to a monitor.

Abstract
A portable, compact closed circuit ventilation device for manual ventilation of a patient undergoing a surgical or medical procedure that requires sedation as well as emergency management of respiratory failure. One example embodiment includes a closed breathing circuit having a manually squeezable bag, a carbon dioxide absorption canister, a plurality of valves, a gas port and a plurality of sensors for measuring Tidal Volume (TV), Peak Airway Pressure (PAP) and End Tidal CO2 (ETCO2). Another example embodiment includes an open breathing circuit having a bag, valves and sensors. A monitor displays the sensor measurements during the respiratory phases. In a spontaneously breathing patient the device may be used to assess the adequacy of patient'"'"'s respiratory efforts. During manual or assisted ventilation, the monitor assures safe and efficacious ventilation by the closed breathing circuit.
