Abstract: A respiratory monitor is disclosed that includes features for conducting multiple pulmonary function tests in a single device and for detecting the presence of nitric oxide in exhaled breath. Also described is a mouthpiece that allows for separate inhalation and exhalation pathways and for filtering inhaled and exhaled breath for predetermined species prior to exhalation into the respiratory monitor. The monitor further allows for wired, wireless and network connectivity and for cloud-based systems for communicating and correlating pulmonary data as well as relevant environmental data and displaying the data for use by patients and health care professionals.

Abstract: A breath collection and storage apparatus is disclosed for collecting and storing samples of exhaled breath for later analysis of nitric oxide contained in collected breath samples. The described apparatus provides for inhaling air into the lungs via a one-way air inflow portal through an airflow chamber via an inhalation/exhalation portal. Air inhaled into the lungs is then expelled back into the airflow chamber via the inhalation/exhalation portal and flowed into a breath storage vessel. A flow meter monitor, such as a flow meter or pressure gauge can be employed to monitor and control the rate of flow of the exhaled breath. A three-way valve can be incorporated into the air outflow portal to selectively permit discharge of exhaled breath to the outside or into the breath storage vessel.

Abstract: A gas detection apparatus for detecting the concentration of a first gas component contained in a gas under measurement includes a gas conversion section for convening the first gas component to a second gas component, a gas detection section whose electrical characteristics change with a change in the concentration of the second gas component when the gas detection section is in an activated state, and a detection state setting section. During a detection period, the detection state setting section sets the state of gas detection by the gas detection section to a detection executed state in which the gas detection section can detect the second gas component. During periods which are not the detection period, the detection state setting section sets the state of gas detection by the gas detection section to a detection suspended state in which the gas detection section does not detect the second gas component.

Abstract: A monitoring system is disclosed that includes features for detecting the presence of biomarkers from a gas sample, such as exhaled breath. An assembly may also includes a plurality of sensors to detect biomarkers present in exhaled breath that are associated with respiratory illness. The biomarkers include carbon dioxide, carbon monoxide, and nitric oxide.

Abstract: A monitoring system is disclosed that includes features for detecting the presence of biomarkers from a gas sample, such as exhaled breath. An assembly includes a plurality of sensors to detect biomarkers present in exhaled breath that are associated with hyperglycemia. The biomarkers include, without limitation, acetone, ethanol, and methyl nitrate.

Abstract: A measurement system is disclosed that includes features for detecting the presence of nitric oxide from a gas sample, such as exhaled breath. The measurement system includes an assembly that introduces one or more reducing gases into a reactor-sensor assembly to help stabilize the sensor signal response and improve the performance of the assembly over time. Suitable reducing gases include hydrogen gas (H2), carbon dioxide (CO), benzaldehyde, bisphenol A, and other similar compounds. The reducing gas may be introduced directly from one or more surrounding gases or through tubing or inline piping. The reducing gas may be generated from the liquid or solid forms.

Abstract: A device for use with a respiratory monitor is disclosed that includes features for collecting and guiding a breath gas sample from a user. The device includes a breath intake structure connected to a handheld body structure. The breath intake structure may include one or more permeable membranes to filter particular substances, such as bacteria, viruses, and microbes, from the breath gas sample before it proceeds through the body structure. The device further includes one or more pre-conditioning elements that pretreats the breath gas sample before it enters a respiratory monitor. In some embodiments, the device may include a mouthpiece and body that are used to collect and guide a breath gas sample to a nitric oxide detection device. Moisture is removed from the breath gas sample using a desiccant loaded into a pre-conditioning cartridge. The mouthpiece may be removably connected to the body and disposable.
