Patent number: 7302949Abstract: 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.Type: GrantFiled: December 3, 2004Date of Patent: December 4, 2007Assignee: Smiths Medical ASD, Inc.Inventors: Richard K. Pelerossi, Fredrick M. Richards, Rex A. Niles, Gregory S. King

Patent number: 7191776Abstract: 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.Type: GrantFiled: May 10, 2004Date of Patent: March 20, 2007Assignee: Smiths Medical ASD, Inc.Inventors: Rex A. Niles, Richard K. Pelerossi, Fredrick M. Richards

Patent number: 6656129Abstract: An improved flow based incentive spirometer operable through a range of user set flow rates and being adapted to receive a supplemental flow of Oxygen without requiring any change in the calibration of the device or effecting the patient's monitoring of usage. In this manner the spirometer may be utilized by a range of patients having quite distinct therapy needs. The device also features an integral information display receptacle in the base for storage of operational instructions. A portion of the base is transparent to that the information contained in the storage receptacle can be viewed by a patient while the device is in use, thereby permitting a patient to observe such things as the instructions for proper use of the incentive spirometer while using the device.Type: GrantFiled: January 18, 2001Date of Patent: December 2, 2003Inventors: Rex A. Niles, Stephen D. Diehl, Patrick W. Olin, Deborah A. Laun, David T. Middleton, Jr.

Patent number: 6253766Abstract: An improved continuous positive airway pressure therapy device including a ring orifice through which compressed air or oxygen is introduced to effectively amplify the air flow to the patient by drawing ambient air into the device inlet for maintaining a continuous positive pressure of a patient's lungs during all portions of the breathing cycle.Type: GrantFiled: August 24, 1999Date of Patent: July 3, 2001Assignee: DHD Healthcare CorporationInventors: Rex A. Niles, Lawrence A. Weinstein, Stephen D. Diehl

Patent number: 5984873Abstract: An improved incentive spirometer adapted to introduce a flow of oxygen across the inlet for inspiratory air so that the oxygen may be drawn thereinto without requiring any change in the calibration of the device or the monitoring of the patient's usage. The device also features an integral information display receptacle in the base for storage of operational instructions. A portion of the base is transparent to that the information contained in the storage receptacle can be viewed by a patient while the device is in use, thereby permitting a patient to observe such things as the instructions for proper use of the incentive spirometer while using the device. The spirometer structure can be utilized for different patient groupings by changing a venturi plate to present a flow restricting orifice designed to accommodate the respiratory therapy and exercise needs for the particular patient grouping.Type: GrantFiled: January 20, 1998Date of Patent: November 16, 1999Assignee: Diemolding CorporationInventors: Douglas M. Crumb, Rex A. Niles, Fredrick M. Richards, Lawrence A. Weinstein
