An oral cannula for placement within the oral cavity of a patient for delivery of a treatment gas and for collecting end-tidal carbon dioxide (ETCO.sub.2) includes a treatment gas delivery lumen including at least one aperture near a distal end of the treatment gas delivery lumen; an end-tidal CO.sub.2 sampling lumen. The cannula also includes a cap having (i) a gas diverter adapted for diverting at least a portion of the treatment gas and (ii) an end-tidal CO.sub.2 inlet including flutes and apertures there between that are in communication with the end-tidal CO.sub.2 sampling lumen. The oral cannula is adapted for custom bending or has a bend such that the oral cannula is insertable and retainable in a patient's mouth and functional for supplying a treatment gas and sampling gas exhaled by the patient.

An infection sensing system includes a sensor device configured to be fastened onto the skin, the sensor device including multiple sensors and a processor coupled to the sensors. The sensors include at least a temperature sensor to read skin temperature as a proxy for body temperature and a heart rate sensor. The processor inputs data from the sensors, determines data representing body temperature and heart rate, and identifies a combination of: (i) a greater than threshold temperature fluctuation in the body temperature, and (ii) a greater than threshold heart rate, where (i) and (ii) are present for greater than a threshold time duration. Responsive to this identification the system outputs data indicating infection.

An apparatus is disclosed comprising a first device for generating aerosol, smoke or vapour from one or more regions of a target, an inlet conduit to an ion analyser or mass spectrometer, the inlet conduit having an inlet through which the aerosol, smoke or vapour passes, and a Venturi pump arrangement arranged and adapted to direct the aerosol, smoke or vapour towards the inlet.

Methods and devices for gaseous sample collection and storage. In an exemplary embodiment of a device for collecting and storing a gaseous sample of the present disclosure, the device comprises a container comprised of impermeable material, a mating section in fluid communication with the container, and a one-way valve disposed in the mating section.

An apparatus for mass spectrometry and/or ion mobility spectrometry is disclosed comprising a first device arranged and adapted to generate aerosol, smoke or vapour from a target and one or more second devices arranged and adapted to aspirate aerosol, smoke, vapour and/or liquid to or towards an analyser. A liquid trap or separator is provided to capture and/or discard liquid aspirated by the one or more second devices.

In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of 2-phenoxyethanol of the user and is obtained by a sensor that detects 2-phenoxyethanol released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of 2-phenoxyethanol per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of 2-phenoxyethanol of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

The health monitoring toilet system includes an extendable, retractable, and rotatable wand with sensors on the head section. The sensors may include a variety of cameras and gas sensors for inspecting a user's urogenital, perineal, and anal region for health assessment. The wand may comprise a bidet wand. The bidet wand may also dispense cleansing and therapeutic substances. The toilet system may include a controller which may store the sensor readings as well as protocols for moving the wand to acquire optimal sensor readings. The controller may be accessible by a healthcare provider for diagnostic and treatment purposes. The toilet system may identify each user to store sensor reading acquired for different users in the controller.

A system and method are provided to detect a possible respiratory blockage by using personalized carbon dioxide (CO.sub.2) concentration change patterns without concerning its absolute values. The personalized change patterns can intelligently learn new change pattern to increase its accuracy. Advanced pattern recognition is used to detect abnormal CO.sub.2 concentration change pattern by comparing to personalized patterns, and allowing the system to trigger alarm to alert a caregiver or a guardian.

To objectively grasp a stress state of a user and to prevent a mental disorder of the user, the following steps are performed: acquiring, via a network, biogas information at multiple timings and time information corresponding to each of the multiple timings, wherein the biogas information represents a concentration of phenol of a user acquired by a sensor that detects phenol discharged from a skin surface of the user; obtaining reference information representing an upper limit of a normal range of the concentration of phenol per unit period of time, using a memory storing the reference information representing the upper limit of the normal range; determining a stress time period during which a concentration of the phenol of the user is more than the upper limit of the normal range, based on the acquired biological gas information; and outputting time period information indicating the determined stress time period to an information terminal of the user, to display the stress time period indicated by the time period information on a display of the information terminal.

A method comprising: acquiring via a network biogas information representing a concentration of 2-ethylhexanoic acid of the user acquired by a sensor that detects the 2-ethylhexanoic acid discharged from a skin surface of the user; obtaining the reference information representing a lower limit of a normal range of the concentration of 2-ethylhexanoic acid per unit period of time, using a memory storing the reference information; and outputting information related to stress of the user an information terminal of the user, after it is determined that a frequency that concentration of the 2-ethylhexanoic acid of the user per the unit period of time is less than the lower limit of the normal range tends to increase, based on the biogas information acquired in a pregnancy period of the user.
