Patent number: 10130786Abstract: A method for reducing a loss of medication from a nebulizer includes the steps of entraining a liquid medication into a first flow of a pressurized gas into a nebulizer chamber and also entraining an additional amount of the liquid medication into a second flow of ambient air drawn into the nebulizer chamber through an opening when a patient inhales through the nebulizer chamber. When the patient exhales, a portion of the exhaled breath is directed into the outlet of the nebulizer chamber, thereby increasing a backpressure within the outlet and substantially stopping the second flow of ambient air into the nebulizer chamber, thereby decreasing the amount of medication lost to the ambient environment while the patient is not inhaling.Type: GrantFiled: January 21, 2016Date of Patent: November 20, 2018Assignee: Vyaire Medical Consumables, LLCInventors: Brian Pierro, Khalid Mansour, Christopher Varga

Patent number: 10092717Abstract: A system and method are configured to utilize patient effort to increase cough flow of a subject by limiting airway collapse by causing a series of exsufflation events over an individual exhalation of the subject. A single exhalation of the subject is segmented into a series of exsufflation events by a processor configured to toggle a pressure regulator between a first airway closed mode and a second airway open mode. The processor is configured such that the transitions between the closed and open modes are initiated based on predetermined timing or based on output signals generated by sensors monitoring one or more gas parameters (for example, pressure) in the airway of the patient.Type: GrantFiled: February 6, 2013Date of Patent: October 9, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Maarten Leonardus Christian Brand, Wei Zhou, Huimin Chen

Patent number: 10086219Abstract: Apparatus and associated methods relate to an automatic fluid alarm that provides a fluid-communication path between a secondary fluid source and a whistle port when a primary fluid source experiences a reduction in pressure, the automatic fluid alarm being user resettable by disconnecting the primary fluid source or otherwise reducing the primary source pressure and activating a reset member, thereby interrupting the fluid-communication path. In some examples, a piston member may provide a movable seal for providing the fluid-communication path and its interruption. An exemplary piston member may be slidably reset in a non-interrupting mode by an adequate primary fluid pressure, and slidably set in an interrupting mode by a user activation. The interrupting mode may silence the whistle which may facilitate user communication during what may be a stressful primary fluid source failure event. Some exemplary automatic fluid alarms may conserve secondary fluid when the whistle is silenced.Type: GrantFiled: January 23, 2014Date of Patent: October 2, 2018Assignee: Honeywell International Inc.Inventors: Jimmy Zheng, Gilles Cordier
