  • Patent number: 10307553
    Abstract: 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.

  • Patent number: 10156232
    Abstract: Provided is a high frequency oscillating ventilator comprising a housing assembly, a linear actuator, a linear coil, a piston mounted on a pushrod, a diaphragm dividing a housing into a first and second side and having an opening formed on the second side that is fluidly connected to the patient's airway for delivering gas thereto. The linear actuator is fixedly mounted to the housing assembly and has a linear coil coaxially disposed therewithin. A pushrod supports the linear coil on the linear actuator to allow relative axially sliding therebetween. The piston is directly mounted to the diaphragm such that reciprocation thereof as effectuated by the linear coil cooperating with the linear actuator alternately produces positive and negative pressure waves in the gas in the patient's airway.
