Abstract
An elbow configured to connect to a positive pressure ventilation mask and to a ventilator circuit that provides a source of pressurized air. The elbow includes an access valve that opens to provide access to the mouth of the patient without removing the mask and seals from ventilator pressure pushing the valve to the closed position.
Claims20
A positive pressure ventilation (PPV) elbow for accessing the oral cavity of a patient wearing a PPV mask under pressure, comprising:
- a housing forming the elbow and defining an air supply conduit extending between an air supply inlet and an air supply outlet, the air supply conduit configured to deliver pressurized air from the inlet to the outlet;
- a mask connector configured to attach to the positive pressure ventilation mask;
- an access port formed through the housing into the conduit, the access port providing access to the mouth of a patient wearing the mask with the elbow connected thereto;
- an access valve positioned in the port, the access valve movable between a closed position and an open position, the access valve configured to open to a diameter of at least 15 mm and configured to self-seal from a ventilator pressure in a range from 8-20 cm H2O, wherein the self-sealing is configured to occur from the ventilator pressure pushing the access valve to the closed position.
A positive pressure ventilation (PPV) elbow for accessing the oral cavity of a patient wearing a PPV mask under pressure, comprising:
- a housing forming the elbow and defining an air supply conduit extending between an air supply inlet and an air supply outlet, the air supply conduit configured to deliver pressurized air from the inlet to the outlet;
- a mask connector configured to removably attach to the positive pressure ventilation mask;
- an access port formed through the housing into the conduit, the access port providing access to the mouth of a patient wearing the mask with the elbow connected thereto,
- the port providing direct access to the mouth of the patient through the mask connector;
- an access valve positioned in the port and configured to open to a diameter of at least 20 mm and less than 30 mm, the access valve including a plurality of leaflets configured to open in response to an object placed therethrough and form a seal therebetween when the object is removed, wherein the leaflets are configured to form the seal from the ventilator pressure in the conduit of the housing and wherein the leaflets are configured to self-revert under a pressure of 8-20 cm H2O after being inverted by removal of the object.
