20100294269 | NEBULIZING DRUG DELIVERY DEVICE WITH AN INCREASED FLOW RATE - The present invention provides a nebulizing drug delivery system for delivering an aerosolized drug to a user having various features to increase the capacity of the drug delivery device. The drug delivery system includes a heater to increase the viscosity of the drug, a double aerosolizing system to double the capacity of the device, and a valve system to continuously replenish drug to the aerosol generator thereby providing a high speed delivery. | 11-25-2010 |
20100313883 | ULTRASONIC BEBULILZER WITH METAL COATED ULTRASONIC GENRATOR - 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. | 12-16-2010 |
20110226242 | RESPIRATORY DRUG DELIVERY APPARATUS WHICH PROVIDES AUDIO INSTRUCTIONS - A respiratory drug delivery apparatus that includes a housing for holding a source of a medication, wherein the housing has a patient interface portion for delivering one or more doses of the medication to an airway of a patient, and a sound generator coupled to the housing. The sound generator is adapted to generate one or more audible instructions in response to an actuation signal. The actuation signal may generated in response to a manual actuation performed by the patient, or in response to the detection of an event relating to operation of the apparatus. | 09-22-2011 |
20110232636 | VALVED HOLDING CHAMBER AND MASK THEREFOR - Various embodiments of a valved holding chamber and a mask for a respiratory drug delivery apparatus each having an exhalation valve element having two portions which, based on the movement thereof, encourages proper use of the device. Also, a valved holding chamber having an MDI adapter having a rigid outer portion and a flexible inner portion structured to receive and hold an outlet of an MDI. In addition, a mouthpiece assembly for a valved holding chamber that includes a main body portion and a mouthpiece portion having a plurality of legs for supporting the valved holding chamber in a first orientation and preventing it from freely rolling. | 09-29-2011 |
20110240015 | METHOD AND APPARATUS COMPRISING STEPPED MOUTHPIECE FOR AEROSOL DRUG DELIVERY - The invention of the present application relates to an apparatus to aid in administering inhaled pharmaceutical aerosol to a patient. The apparatus is used in conjunction with an aerosol delivery device. The apparatus comprises steps on the top and bottom of the apparatus, which when used aid the patient causes mandibular advancement, and opening of the mouth, causing opening of patient's airway, resulting in improved aerosol lung deposition. The invention also relates to a method of using such apparatus in a combination with an aerosol delivery device or a system, and to the mouthpiece of said apparatus. | 10-06-2011 |
20110247616 | SYSTEM AND METHOD FOR DISPENSING MEDICAMENT INTO A VENTILATOR CIRCUIT - 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. | 10-13-2011 |
20110247624 | MASK AND METHOD FOR DELIVERING A THERAPEUTIC BREATHABLE SUBSTANCE - 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 | 10-13-2011 |
