  • Publication number: 20220226598
    Abstract: Provided herein are devices, systems, and methods for introducing a nebulized medication into breathing gas for respiratory therapy. An apparatus includes a reservoir to contain a volume of medication, a vibrating mesh disposed at a reservoir outlet of the reservoir to receive a flow of the medication from the reservoir and output a flow of nebulized medication, a mixing chamber having a gas inlet to receive a flow of breathing gas from a gas source, and a nebulizer inlet to receive the flow of nebulized medication from the vibrating mesh, where the vibrating mesh is disposed between the nebulizer inlet and the reservoir outlet. The apparatus can include a pressure tap tube or other implement in fluid communication with the mixing chamber and the reservoir to selectively equalize pressure between the mixing chamber and a headspace in the reservoir above the volume of medication.

  • Publication number: 20220096777
    Abstract: Devices and methods are provided herein for sensing and monitoring of patient breathing during high flow respiratory therapy. A nasal cannula having a sensing lumen and remotely-located pressure sensor is provided herein for breath sensing that provides an accurate and clear signal while high flow rates of breathing gas are delivered from the nasal cannula. Condensation can be removed from the sensing lumen by applying a constant, pulsatile, or burst flow of purge gas. The breath sensing apparatus can be integrated in a respiratory system with a breathing gas source or can be packaged as a separate device capable of adapting to a variety of systems.

  • Publication number: 20210285435
    Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfectants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

  • Publication number: 20210283357
    Abstract: The systems, devices, and methods described herein relate to providing breathing gas to a patient using a base unit and an auxiliary unit configured to be removably disposed on or at least partially in the base unit. The base unit has several couplings for improved control and sensing of the auxiliary unit and its components, wherein the couplings are configured to be non-contact with the corresponding components of the auxiliary unit and/or otherwise configured to minimize operational defects or improve efficiency. Non-contact couplings include induction heating, capacitive level sensing, a magnetically coupled rotor pump, RFID tag and reader, and Hall effect sensing. The breathing gas can be provided at high velocities by setting breathing gas flowrates based on dimensions of a nasal cannula used to direct the breathing gas into a patient's nares.

    Abstract: Provided herein are devices, systems, and methods for providing respiratory therapy to a patient using a nasal cannula comprising a cannula body, first and second inlet tubes, and a nasal prong for the delivery of a flow of breathing gas to the patient. Configured with the cannula is a nebulizer having an aerosol generator positioned to emit aerosolized medicament along a longitudinal axis of the nasal prong. A flow director is configured to direct the flow of breathing gas into the nasal prong such that the breathing gas flows along the longitudinal axis, such that the flow of aerosolized medicament is contained within the flow of breathing gas as it moves along the longitudinal axis of the nasal prong for delivery to the patient.
