Patent number: 8534284Abstract: A respiratory therapy device including a housing and an interrupter valve assembly. The housing is sized for handling by a patient and defines a patient breathing passage extending from a patient end and through which a patient inhales and exhales air. The interrupter valve assembly is carried by the housing and includes a control port, a valve body, and a drive mechanism. Expiratory airflow is released from the patient breathing passage through the control port. The valve body is sized to at least partially obstruct fluid flow through the control port. The drive mechanism moves the valve body relative to the control port in response to the expiratory airflow such that the valve body repeatedly transitions between a position of maximum obstruction and a position of minimum obstruction relative to the control port to create an oscillatory positive expiratory pressure effect.Type: GrantFiled: September 27, 2011Date of Patent: September 17, 2013Assignee: CareFusion 2200, Inc.Inventors: Thomas J. Dunsmore, Geoffrey C. Wise, Thomas C. Wilschke, Christopher J. Matice, Christopher L. Gillum, Shannon Rice Read

Publication number: 20120109186Abstract: An articulating laparoscopic instrument including a handle body, a shaft, an end effector, an operation mechanism, and an articulation mechanism. The end effector is connected to a shaft end. The operation mechanism includes a rod and an actuator. The rod is coupled to the end effector. Movement of the actuator relative to the handle body transfers a force onto the rod in a longitudinal direction to operate the end effector. The articulation mechanism includes a deflection assembly, first and second collar assemblies, first and second cables, a linkage, and an articulation actuator. The first and second collar assemblies are slidably disposed over the rod. The cables extend between the collar assemblies and the deflection assembly. Movement of the articulation actuator drives the first and second collar assemblies in opposite directions to cause a longitudinal deflection in the deflection assembly.Type: ApplicationFiled: October 29, 2010Publication date: May 3, 2012Inventors: David A. Parrott, Benjamin T. Krupp, Christoph L. Gillum, Christopher J. Matice, Louis P. Mingione

Publication number: 20100307487Abstract: A respiratory therapy device including a housing and an interrupter valve assembly. The housing includes a patient inlet, an exhaust outlet, a chamber, and a supply inlet. The interrupter valve assembly is associated with the housing and includes a control port fluidly connecting the patient inlet and the first chamber, and a valve body adapted to selectively obstruct fluid flow through the control port. In a passive mode, positive fluid flow to the supply inlet does not occur, and the interrupter valve assembly interacts with exhaled air create an oscillatory PEP effect. In an active mode, fluid flow to the supply inlet occurs and the interrupter valve assembly operates to create a CHFO effect. The respiratory device can serve as a passive oscillatory PEP device, and when connected to a positive pressure source, as an active device.Type: ApplicationFiled: August 17, 2010Publication date: December 9, 2010Applicant: CareFusion 2200, Inc.Inventors: Thomas J.

Patent number: 7219819Abstract: A valve assembly has a valve housing and a valve core body movable therewithin for providing a smooth and continuous outflow of liquid from a container, which may be unvented and rigid, through a liquid-out passageway, and provides an air-back passageway for drawing external air into the container. In a preferred embodiment, the core is rotatable within the housing by one-handed actuation. The air-back passageway is preferably a channel provided on the surface of the core body, and the liquid-out passageway is preferably provided between openings in the core body.Type: GrantFiled: October 24, 2003Date of Patent: May 22, 2007Assignee: Nestle Waters North America, Inc.Inventors: J Wayne Halfacre, John S Gruver, Christian Randhahn, Charles A Curtiss, Stuart Leslie, Christopher J Matice, Stephen P DeHoff
