Abstract: A nebulizer system includes a body having a fluid chamber and an aerosol chamber, and a vibrator assembly positioned at an interface between the fluid chamber and the aerosol chamber. The vibrator assembly may include a diaphragm, having a fluid side and an aerosol side, defining a plurality of perforations between the fluid side and the aerosol side, and one or more vibrator elements operatively associated with the diaphragm to vibrate the diaphragm to produce aerosolized medicament projected into the aerosol chamber from the plurality of perforations. Each perforation of the plurality of perforations projects the aerosolized medicament along a respective projection path relative to a plane defined by the aerosol side of the perforation, the one or more vibrator elements or the diaphragm support substrate further being configured to angularly displace the aerosol side of the diaphragm to sweep the direction of at least one projection path.

Abstract: A non linear, medicated aerosol holding and delivery chamber without sealing valves at the aerosol inlet and outlet ends. There is a low pressure actuated, vacuum relief, drain check valve at the bottom end of the chamber and an overpressure relief valve at the top end adjacent the mouthpiece opening. The vacuum relief, drain check valve has a radial support plate beneath it that allows for the creation of a vortex in the aerosol plume. The drain check valve also provides for the complete return of any condensed aerosol to the nebulizer when closed. The overpressure relief valve efficiently allows dispelling of the patient's air. Both valves aid in the decrease of the MMAD of the medicated aerosol particles. There is no truly enclosed volume defined by the body of the chamber as the mouthpiece is open into the top of the chamber body, free of any valves.

Abstract: An improved oscillating positive expiratory pressure (“OPEP”) device, for respiratory therapy having a self sterilizing flow valve capable of insertion into the curved OPEP body without tools or aids. The flow valve is also tear resistant and incorporates a flared reinforced proximal end. To maximize the benefit to patients, the adjustable therapy selector is constrained from withdrawal and is dimensioned to accept commercially available, standardized respiratory fittings adaptors, mouthpieces and “Tees” that are capable of connection to multiple respiratory therapy devices or medicated aerosol delivery units. The aesthetics have been altered by the addition of an arced handle.

Abstract: A respiratory medicament and therapy data system capable of using a “breath actuated” monitoring device that monitors patient interactions with all respiratory therapy and drug delivery devices. It generates a signal based on the magnitude, direction and duration of the inhalation and exhalation pressures generated by a patient. This allows the tracking and wireless reporting of the various therapeutic and medicament delivery sessions with respect to such parameters as delivery date, time, duration, total delivered dose and the like. The respiratory medicament and therapy data system provides a fool-proof system for recording and immediately displaying the results of the respiratory therapy or drug delivery that have been algorithmically derived on a localized device and that can be sent to the medical provider's patient treatment database (health portals) for later, remote review by medical personnel.

Abstract: A Tee piece that functions as device to direct dual, alternating respiratory therapies to a patient. It has a centrally located low pressure actuated one way valve that connects the inhalation and exhalation paths to the specific therapy devices. The gravity hung valve has a low pressure activation and an offset, angled seat that allows the valve itself to be completely removed from the path of the medicated aerosol particles so as to minimize the potential for particle condensation by collision with the valve. The valve forms a holding chamber for the medicated aerosol increasing the efficiency of the nebulizer cycle. The physical design of the Tee piece's outside surface prevents reverse connection, which is a common problem and the oval shape of the PEP port eliminates blow-off of the PEP device by excessive back pressure.
