Publication number: 20240082104Abstract: Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user.Type: ApplicationFiled: November 10, 2023Publication date: March 14, 2024Inventors: Michael Austin Johnson, Jason Adams, Jean-Pierre Delplanque, Justin Koos, Gregory Rehm

Patent number: 11813050Abstract: A selective-sorting system for aerosol droplets in human breath includes a mouthpiece to receive a flow of human breath, and a flow path coupled to the mouthpiece. This flow path includes one or more bends that cause the flow of human breath to change direction, which causes aerosol droplets in the flow having different mass-sizes to change direction at different rates. Moreover, the flow path is shaped so that droplets that change direction at different rates are directed to different destinations. The system also includes a collection path, which is coupled to the flow path so that aerosol droplets meeting a specific mass-size criterion are directed into the collection path. A condenser tube is located in the collection path, wherein the condenser tube includes a cooling mechanism that cools the condenser tube to facilitate condensing aerosol droplets to sides of the condenser tube for subsequent collection.Type: GrantFiled: November 22, 2017Date of Patent: November 14, 2023Assignee: The Regents of the University of CaliforniaInventors: Cristina E.

Patent number: 10111606Abstract: An integrated condenser is described. This integrated condenser includes an outer surface region on a sampler surface that facilitates condensing at least a component in a received gas-phase sample into liquid-phase droplets on the sampler surface, and aggregating and moving the condensed droplets radially toward an inner surface region on the sampler surface that receives the condensed droplets. For example, the outer surface region may include a set of micro-patterned concentric rings, each of which includes a set of radially oriented wall-groove pairs. Moreover, the sampler surface may be increasingly less hydrophobic along a radial direction toward the center of the sampler surface, thereby creating an axisymmetric wettability gradient.Type: GrantFiled: January 25, 2013Date of Patent: October 30, 2018Assignee: The Regents of the University of CaliforniaInventors: Cristina Davis, Hamzeh Bardaweel, Konstantin Zamuruyev, Jean-Pierre Delplanque, Nicholas J.

Publication number: 20150164373Abstract: A personal lung function monitoring device capable of exhaled breath analysis is described. The personal lung function monitoring device includes a physical measuring device and a microcontroller. This physical measuring device further includes a flow chamber configured to receive a flow of exhaled breath from a patient/user, and a set of sensors integrated with the flow chamber. The set of sensors can be used to measure a set of properties of the exhaled breath, which can include one or more common lung function parameters and/or one or more biomarkers of the exhaled breath. The microcontroller is coupled to the physical measuring device and configured to receive analog sensor signals from the set of sensors and transmit the digitized sensor signals to a mobile device. In one embodiment, the personal lung function monitoring device combines peak expiratory flow, spirometry, and exhaled breath biomarker measurements into a single device.Type: ApplicationFiled: June 11, 2013Publication date: June 18, 2015Inventors: Cristina E.
