Abstract: The present invention is directed to a Continuous Positive Airway Pressure Device as an apparatus configured to provide positive airway pressure in a respiratory circuit that comprises a container configured to be filled to a preselected level with liquids; a drop tube assembly comprising a hollow gas tube rotatably mounted in said container having an upper end extending a static distance outwardly of the container and connected to a respiratory circuit downstream of a user, and a hollow drop tube reciprocally movable upwardly and downwardly in the liquid in response to rotational movement of the gas tube. The container is provided with a gas vent and a liquid fill port.

Abstract: The improved device is used in the present method for cleansing the head of a stethoscope with an antimicrobial spray liquid. The device includes a housing which defines a generally central cavity in which an aerosol spray cannister is releasably disposed in a bracket. The housing is closed but is openable in order to replace the cannister, as needed. The housing includes an openable port, such as an elastomeric iris, through which the head of a stethoscope, in accordance with the present method, is inserted for cleansing in the cavity. The cannister has a spray nozzle which is activatable by a trigger in the form of a lever secured in the cavity and extending out of the housing. The lever is disposed above the nozzle and can be manually moved from outside the housing to depress the nozzle and cause antimicrobial spray to be aerosol dispensed from the cannister in a path in the cavity which the stethoscope head intersects.
