A bypass filter comprising a conduit having a main passageway configured for passage of fluid from an upstream end of the conduit to a downstream end of the conduit; The bypass filter further comprises a main filter located within the main passageway and configured for preventing passage therethrough of a predetermined substance within the fluid, while allowing a remainder of the fluid to pass towards the downstream end of the conduit; The bypass filter has an upstream opening in the conduit located upstream of the main filter and being in fluid communication with the main passageway at an upstream end of the conduit and a downstream opening in the conduit located downstream of the main filter and being in fluid communication with the main passageway at a downstream end of the conduit; The bypass filter also comprises an auxiliary filter being in fluid communication with both the upstream opening and the downstream opening for passing the fluid between the openings while at least partially absorbing the substance.

An oxygen mask configured for COsampling and oxygen delivery, the oxygen mask having an oxygen inlet, a nasal breath-sampling element and a breath sampling port configured to receive breath samples, sampled by the breath-sampling element, wherein the breath-sampling element is configured to reduce dilution of exhaled breath by the delivered oxygen.

Capnoxygen masks

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 CO, and they configured such that exhaled COquickly fills them up, during exhalation, and while expelling oxygen traces back to the oxygen reservoir space. During exhalation.

Oxygen-capnography mask for continuous COmonitoring

Disclosed herein are facially fitting devices, such as nasal cannulas and oxygen masks, including illuminating placement marker(s), which facilitate correct placement of the facially fitting devices on a face of a subject in dark conditions. The placement marker is powered by a thermo-electric generator, which generates electrical power via thermal coupling thereof to skin on the face of a subject when the facially fitting device is fitted, or partially fitted, on the face of the subject.

Facially fitting devices with illuminated placement markers

A device for measuring a concentration of a component in a target sample includes a flow chamber with a first channel that receives a reference sample having a known concentration of the component. The flow chamber also includes a second channel that receives the target sample having an unknown concentration of the component. A pump operates to pump the reference sample and the target sample at a same volume flow rate through the first and second channels, respectively. A thermal mass flow meter measures a thermal conductivity of the reference sample, a thermal conductivity of the target sample, or both.

Device, system and method for thermal capnography

Disclosed herein are systems and methods for producing an illumination pattern in a gas tube of a facially-fitting device, which is used in conjunction with a capnograph. The illumination pattern is determined by at least one illumination parameter, derived at least from measured COdata, such that the illumination pattern is indicative of at least one breath-related/physiological parameter and/or one or more of the respiratory/physiological conditions determined/assessed based at least on the COdata.

A pneumatic system for delivering oxygen to a subject, including an oxygen supply channel having an inlet, a patient delivery outlet and an exhaust; and a flow control element configured to control the flow from the oxygen inlet to the patient delivery outlet, or to the exhaust; wherein inhalation by the patient causes the flow control element to assume a first position, allowing oxygen to flow from the oxygen inlet to the patient delivery outlet; and wherein exhalation by the patient causes the flow control element to assume a second position, directing oxygen flow from the oxygen inlet to the exhaust.

Pneumatic system for controlled oxygen delivery

A gas flow-focusing device (FFD) may include a cylindrical body that may include a funneling part to receive exhaled CO2-enriched air, and a CO2 sampling part. The CO2 sampling part and the funneling part are in fluid flow communication. The CO2 sampling part may include a CO2 sampling chamber to accept the CO2-enriched air, and a CO2 sampling tube to sample the CO2-enriched air. The funneling part and the CO2 sampling part may structurally form between them a ring-shaped gas chamber to contain a pressurized propellant gas, and a hollow channel in order to channel the pressurized propellant gas from the gas chamber to the CO2 sampling chamber. The gas chamber may include a gas intake opening through which propellant gas may fill the gas chamber. A prong-free cannula (PFC) may include two FFDs for sampling CO2, and a plurality of apertures for providing, there through, oxygen.

Prong-free cannula device for COsampling and Odelivery

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.

Device, system, and method for filter reconstitution

A COmonitoring system provides oxygen (O) to a subject's mask with known characteristics. The COmonitoring system receives, from the mask, gas samples including exhaled COdiluted by O. The COmonitoring system uses an adaptive noise canceller to cancel the diluting Oby using the known characteristics of the Oprovided to the mask, the result of which process is restoration of the original concentration level of the COas exhaled by the subject into the mask.

Systems and methods for concomitant COsampling and Odelivery

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.
