    摘要： A metered dose inhaler (MDI) spacer has a body that defines a dose receiving chamber. A proximal end portion coupled between the body and a mouth port through which a metered dose may be inhaled by a user of the MDI spacer. A distal end portion is coupled with the body. A combined one-way and flow rate control valve coupled with the distal end portion is configured for permitting external airflow into and prohibiting internal airflow out of the dose receiving chamber. A collar coupled with the distal end portion is configured for receiving an actuator shaft of a metered dose inhaler and for forming a seal about an aerosol nozzle of the metered dose inhaler such that a metered dose of medication is admissible into the dose receiving chamber via the collar while airflow into and out of the dose receiving chamber via the collar is prohibited.

    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 first and second jets, a flow director and an exhaust conduit. The jets emit a jetstream into the flow director in a direction of a patient side thereof. In some embodiments, the flow director forms a first tapered wall section directing inhaled air toward the patient and a second tapered wall section directing exhaled air toward the exhaust conduit. The generator body requires reduced driving pressures to achieve target CPAP levels and reduces total imposed WOB as compared to conventional designs.
