A face mask including a mask assembly and a hole punch assembly is disclosed. The mask assembly includes a face mask which includes a mouth portion and a nose portion. Additionally, the face mask is made of a transparent material allowing other individuals to identify the user wearing the mask. Furthermore, the face mask includes two embodiments of strap attachments. In one embodiment a single strap is used to secure the face mask to a user's head. In another embodiment, two strap loops are used to secure the face mask to a user's ears. The hole punch assembly includes a hole punch rod that is used to create openings on the face mask. The hole punch rod is used to create openings on the mouth portion and nose portion of the face mask. A medical professional may utilize these openings to collect samples from a patient wearing the mask.

A gas sensor kit includes a gas sensor that measures a gas concentration of an exhalation gas of a subject and a gas supply unit that supplies a therapeutic gas, supplied through a tube, to the subject. In the gas sensor, the gas sensor has a convex portion that is supported when connected with the gas supply unit, and the gas supply unit has at least one locking claw that supports the convex portion when connected with the gas sensor.

The present invention provides a device for non-invasive monitoring and/or detection of diabetes in a subject based on detection of volatile organic compounds (VOCs) in the exhaled breath of a subject. The device comprises a functionalized carbon nanotube-based array sensor which can reversibly bind VOCs, which alters the electrical conductivity of the sensor array, which can be interpreted to monitor and/or diagnose diabetes.

Disclosed are a drunk driving prevention system and a method of controlling the system that includes a sensor module measuring a alcohol content in the exhaled breath of a driver during a breath-checking of the driver and a control module configured to check the intoxication state of the driver from the alcohol content measured by the sensor module to determine whether the breath-checking is complete and block an engine start when the breath-checking fails, wherein the control module includes a check unit displaying breath-checking guide information through a display unit and the check unit displays the breath-checking guide information based on an engine start input of the driver.

A flow regulation device for volatile and semi-volatile sampling onto adsorbent media is provided. The flow regulation device includes a housing having an inlet, an outlet, a secondary inlet that is open to the ambient, a real time flow meter, a controller in electronic communication with the flow meter, and a three-way valve. Gas is drawn through the adsorbent media, into the inlet, and then to the outlet by a vacuum source joined to the outlet. The controller is configured to: (1) actuate the three-way valve to put the vacuum source in-line with the inlet; (2) continuously monitor the flow of gas through the inlet and calculate the time necessary to sample a pre-set volume of gas; and (3) after the pre-set volume of gas passes through the inlet, actuate the three-way valve to put the vacuum source in-line with the secondary inlet.

Various systems, devices, components, and methods are disclosed for measuring the concentration of an analyte, such as acetone, in a breath sample. The disclosed devices include a breath sample analysis device having a mouthpiece configured to facilitate engagement with a user's mouth to receive a breath sample. The disclosed devices also include a breath sample capture cartridge containing an interactant that extracts the analyte from a breath sample passed through the cartridge. Also disclosed are devices for routing the breath sample through the cartridge during exhalation, and for analyzing a reaction in the cartridge to measure a concentration of the analyte.
