Abstract: A nebulizer includes a piezoelectric transducer for aerosolizing a drug solution in a disposable cup module disposed above the transducer. Acoustic waves generated by the transducer propagate sequentially through transmitting medium, a first barrier, coupling medium, and a second barrier that forms part of the cup module, and into the interior of the cup module. The transducer at least partially comprises silver. The silver fluidly contacts the transmitting medium to discourage bacteria growth in the transmitting medium. The device includes electronics components that drive the transducer and measure an electrical characteristic associated with the transducer during operation. The electronics components measure changes in the electrical characteristic to determine when the drug solution level falls below a predetermined threshold, and deactivates the device accordingly.

The present invention also has a drug detection device that can detect the volume of drug in the device or whether the barrier has been compromised.

Abstract: A mask may be used in therapeutic gas delivery to one or more external orifices (e.g., the nostrils and/or mouth) of a subject in accordance with an embodiment of the present invention. The mask may include a mask body, a seal portion, a source connector, and an exhaust valve. The mask may be configured to be placed against the face of the subject 12 with a sealed interface therebetween such that a chamber is formed by the mask and the face of the subject that encloses the one or more external orifices of the subject. During use, a breathable substance can be provided into the chamber from a source of the breathable substance through the source connector.

Abstract: A drug delivery adapter is configured to facilitate the delivery of one or more medicaments to a subject being ventilated by a circuit (not shown). The circuit may be a ventilator circuit, or the like, configured to convey a pressurized flow of breathable gas to the airway of the subject. The ventilator circuit may form a flow path between a pressure generator and the airway of the subject to deliver a pressurized flow of breathable gas from the pressure generator to the airway of the subject. The drug delivery adapter, in particular, is configured to enable the delivery of one or more medicaments into the pressurized flow of breathable gas being conveyed to the subject by the circuit without compromising the integrity of the circuit through the introduction of ambient air. To facilitate this delivery, the drug delivery adapter is configured to dock one or more types of medicament dispenser.

Abstract: The present invention pertains to a valved holding chamber suitable for use in an aerosol medication delivery system. The valved holding chamber includes a housing and a mouthpiece coupled to the housing. A one-way valve assembly is coupled to the housing, the mouthpiece, or both so that fluid flows in a first direction from the housing to the mouthpiece passes through the valve assembly but does not pass back into the housing. The valve assembly includes a conical flange disposed such that the conical flange tapers in the first direction to smooth the fluid flow in the first direction toward the patient. In a further embodiment, the mouthpiece includes an exhaust port defined in a conical collar portion of the mouthpiece, and an exhaust valve element is disposed over the exhaust port to provide a one-way flow of fluid from within the mouthpiece to ambient atmosphere via the exhaust port.

Abstract: The present invention provides a drug delivery device having a housing that includes a ventilator interface module and a base module removeably coupled to the ventilator interface module. An aerosol generator is disposed in the base module to nebulize a drug solution provided in the housing.
