摘要： An nCPAP device for assisting patient breathing includes a generator body forming an inlet, a chamber, and first and second flow circuits. The chamber directs pressurized gas from the inlet to the flow circuits. The flow circuits each include a nozzle, a channel, and at least one port. The nozzle emits a jet stream into the channel in a direction of a patient side thereof. The port fluidly connects the channel to ambient, and promotes entrainment of ambient air with the jet stream. In some embodiments, the channel forms a ramp feature directing exhaled air toward the jet stream in an angular fashion. The generator body requires reduced driving pressures to achieve target CPAP levels and reduces total imposed WOB as compared to conventional designs.

摘要： The present invention includes an apparatus and a method for testing exhaled breath condensate for at least one biometric marker, including a substrate for collecting exhaled breath condensate, the substrate capable of being brought to a temperature below a dew point of vapor in exhaled breath, a collector for retaining the substrate and for receiving a biometric marker reagent. The invention may further include receiving exhaled breath in a collector, the collector comprising a substrate, the substrate being at a temperature below a dew point of vapor in exhaled breath, collecting the exhaled breath condensate on the substrate, and bringing a biometric marker reagent in contact with the substrate.
