Abstract: A multi-use, hand held, single patient oscillatory positive expiratory pressure respiratory therapy device which is easily assembled and disassembled for cleaning, and which is not position dependent during therapy, but operable through a wide range of device orientation.

Abstract: An improved humidifier which may be used with a nasal cannula for high-flow respiratory gas therapy wherein a sterilized liquid is drawn from a sterilized liquid container by a high-flow driving gas passing adjacent to an aspirator tube orifice through which the sterilized liquid is drawn into contact with the driving gas for fracturing the liquid into a mist which is warmed and delivered to the patient or user, and the driving gas is also passed adjacent a condensate return orifice which draws any condensate formed in the humidified respiratory gas delivery system away from the cannula and back into the system for re-use.

Abstract: An improved nebulizer breathing system wherein a supplemental gas may be introduced into the nebulizer head at a position after the liquefied medication has been fractured or nebulized, so that the introduction of the supplemental gas does not effect the rate at which the nebulized liquefied medication is applied to the user, and the mixture of gases to be administered to a patient is added to the breathing system at a position removed from the point at which the gas mixture is administered to the patient.

Abstract: A multi-use, hand held, single patient oscillatory positive expiratory pressure respiratory therapy device which is easily assembled and disassembled for cleaning, and which is not position dependent during therapy, but operable through a wide range of device orientation.

Abstract: A nebulizer having a supplemental gas inlet port carried by the nebulizer head at a position removed from the nebulizer chamber so that the supplemental gas introduced does not entrain the liquid medicant effecting the rate of medication application to a user.

Abstract: An oscillatory positive expiratory pressure respiratory therapy device which may be incorporated into the expiratory limb of a ventilator circuit. Accordingly, this device allows a patient on a ventilator to be subjected to positive expiratory pressure (PEP) therapy combined with airway oscillation and intermittent air flow acceleration while allowing the oscillatory PEP respiratory therapy treatment to be bypassed without interrupting the integrity of the ventilating circuit once the device has been installed in the ventilator circuit. In this manner, all expiratory air in the ventilator circuit is accounted for, the expiratory air volume may be accurately monitored and the ventilator circuit does not have to be broken for insertion or removal of the device.
