Abstract: A face mask for delivering oxygen to, and sampling carbon dioxide exhaled from, a subject includes a partition wall that divides the mask into a subject respiratory space that primarily contains carbon dioxide exhaled by the subject, and an oxygen reservoir space that primarily contain oxygen. The partition wall includes one or two holes to which naris conduits are respectively connected. The naris conduit are positioned in proximity to the subject's nares to closely obtain carbon dioxide samples. The naris conduits enable oxygen to flow from the oxygen reservoir space to the subject respiratory space during inhalation, while quickly expelling traces of CO2, and they configured such that exhaled CO2 quickly fills them up, during exhalation, and while expelling oxygen traces back to the oxygen reservoir space. During exhalation.

Abstract: A device for reconstituting a filter and/or a filter-containing consumable for use in breath monitoring, the device including a connector socket that may receive and/or mate with the filter or filter-containing consumable, a pump that may pump ambient air into a chamber of the device, an inlet that may allow flow of oxygen into the chamber, a UV source that may catalyze the formation of ozone from the oxygen, thereby obtaining ozone enriching air in the chamber, and an outlet that may eject the ozone enriched air, from the chamber, into the filter, thereby reconstituting the filter and/or the filter-containing consumable.

Abstract: A bi-functional filter device for removing liquid from a humid gas flowing through the filter device includes a filter body that includes an axial through-channel that passes lengthwise through the filter's body, through which gas (e.g., humid gas) can flow, and a dehumidifier sleeve that encloses the filter body. The filter body includes a capillary path that may absorb, and thus remove, liquids, for example laterally, radially or spirally (in spiral manner) from the through-channel of the filter body using capillary action, to thus clear the through-channel of the filter body from these liquids. The dehumidifier sleeve may evaporate liquid contained in (and arriving from) the filter body.

Abstract: A fluid filtering device for separating liquid from gases includes a filter located within the lumen of the filtering device. The filter blocks materials other than gases from passing therethrough. A element fluidly coupled to the filter provides an indication to a user once liquid in the lumen is at a predetermined threshold level.

Abstract: The subject matter discloses a noninvasive method and device for detection, measurement and monitoring of Pulmonary Interstitial fluid—Extravascular Lung Water —volumes in inpatient settings: Intensive Care Units, Emergency Rooms, Internal Hospital Departments, and daily monitoring of chronic patient in outpatient settings: outpatient departments, rehab centers and Home monitoring. The disclosed method is based on the analysis of lung tissue thermodynamic properties, and their deviation from normal value. The device measures the rate of temperature change of a lung tissue by measuring the exhaled gas temperature changing rate during cooling/heating of lung tissue. The cooling/heating of lung tissue may be achieved by prompt changing one of the inhaled gas parameters temperature, and/or humidity, and/or rate of breathing, and/or tidal volume, and/or type of gas and etc. The change is performed at the beginning of measurement, and is kept during entire measurement time.

Abstract: A method and system for regional assessment in two or more regions of an individual's lungs. The system includes a plurality of transducers configured to be fixed over the thorax. Each transducer generates a signal P(xi,t) indicative of pressure waves at the location of the transducer. The transducers are divided into subsets, where each subset overlies a specific region of the two or more regions. An energy assessment signal is calculated from each of the signals P(xi,t). For each region, an assessment of the region is calculated from the energy assessment signals of the region.
