Abstract
An adaptor for generating flow includes an adaptor housing body. The distal end of the body has an oxygen inlet that extends extending into an interior of a distal air intake portion. The oxygen inlet has a nozzle with at least two apertures for directing oxygen into an interior of a distal air intake portion. The distal air intake portion includes at least one air inlet port to allow air to be drawn into the interior of the distal air intake portion, and a flow-resisting media covering at least a portion of the at least one air inlet port.
Claims20
An adaptor for generating flow, the adaptor comprising:
- an adaptor housing body, the adaptor housing body comprising a distal end and an open proximal end for attachment to a patient interface;
- the distal end of the adaptor housing body having an oxygen inlet, the oxygen inlet comprising a coupler on an exterior side for connection to an oxygen source, the oxygen inlet extending into an interior of a distal air intake portion, and the oxygen inlet having a nozzle with at least two apertures for directing oxygen into an interior of a distal air intake portion;
- the distal air intake portion comprising at least one air inlet port to allow air to be drawn into the interior of the distal air intake portion,
- a proximal portion in communication with the distal air intake portion, the proximal portion forming a throat having a first circumference and an outlet having a second circumference for connection to a patient interface, the first circumference being smaller than the second circumference, the proximal portion further comprising at least one of a pressure measuring port and a gas sampling port.
An adaptor for generating flow, the adaptor comprising:
- an adaptor housing body, the adaptor housing body extending from a distal end to an open proximal end, the open proximal end for attachment to a patient mask;
- the distal end of the adaptor housing body having an oxygen inlet for coupling to an oxygen source, the oxygen inlet extending into an interior of a distal air intake portion, and the oxygen inlet having a nozzle with at least one aperture for directing oxygen into the interior of a distal air intake portion;
- and
- the distal air intake portion comprising at least one air inlet port to allow ambient air to be drawn into the interior of the distal air intake portion, a flow-resisting media covering at least a portion of the at least one air inlet port.
An adaptor for generating flow, the adaptor comprising:
- an adaptor housing body, the adaptor housing body comprising a distal end and an open proximal end for attachment to a patient interface;
- the distal end of the adaptor housing body having an oxygen inlet, the oxygen inlet comprising a coupler on an exterior side for connection to an oxygen source to convey pressurized oxygen from a pressurized oxygen source in connection with the coupler to the adaptor;
- the oxygen inlet extending into an interior of a distal air intake portion, and the oxygen inlet having a nozzle with at least two apertures for directing oxygen into an interior of a distal air intake portion;
- and
- the distal air intake portion comprising at least one air inlet port to allow air to be drawn into the interior of the distal air intake portion, and a flow-resisting media covering at least a portion of the at least one air inlet port.
