Breath Analysis Patents (Class 73/23.3)
  • Patent number: 10682072
    Abstract: A breath analyte device includes a breath volume in fluid communication with a sampling volume. The device also includes a sampling sensor configured to generate a breath signal that varies in response to changes in gas pressure (e.g., sound waves) in the breath volume and an analyte sensor configured to generate an analyte signal that varies in response to a concentration of a target analyte present in the sampling volume. A control unit is configured to determine a time at which to measure the concentration of the target analyte in the sampling volume based on the breath signal and measure the concentration of the target analyte in the sampling volume based on the analyte signal at the determined time. The device may also include a pump configured to motivate gas from the breath volume into the sampling volume prior to measuring the concentration of the target analyte.

  • Patent number: 10655362
    Abstract: A breathalyzer car key locking device comprises a mouthpiece, an alcohol sensor, a locking mechanism, and a processing element. The mouthpiece receives breath from a user. The alcohol sensor receives the user's breath from the mouthpiece, determines a blood alcohol level of the breath, and outputs an electronic blood alcohol level signal whose voltage level or digital data value varies according to the determined blood alcohol level. The locking mechanism exists in one of two states including a locked state and an unlocked state. The locking mechanism retains a car key in the locked state and releases the car key in the unlocked state. The processing element receives the blood alcohol level signal from the alcohol sensor, and transmits an electronic locking signal that places the locking mechanism in the locked state when an aspect of the blood alcohol level signal is greater than or equal to a predetermined threshold.

  • Patent number: 10488397
    Abstract: Improved sensor assemblies are provided. More particularly, the present disclosure provides improved and highly advantageous metal oxide based sensor assemblies configured to sense low concentration of specific gases, and related methods of use. The present disclosure provides improved physical forms of metal oxide films (e.g., WOx films, CeOx films). The exemplary metal oxide films can be fabricated by a Reactive Spray Deposition Technology (RSDT). The highly advantageous films/materials can be utilized in sensor assemblies to detect simple chemical components of the breath that correlate with human health conditions (e.g., the presence of acetone in diabetic patients). These films/materials demonstrate improved thermal stability under the sensor's operating conditions, as well as improved sensitivity to low concentration of the analyte, selectivity and quick responsiveness.

  • Publication number: 20140305189
    Abstract: A method for continuous measurement of differences in gas concentrations, comprises providing at least first and second gas analyzers, connecting a stream of incurrent fluid to a chamber containing an animal, withdrawing air from the chamber to form a stream of excurrent fluid, taking first subsamples of the excurrent fluid in a first subsampler, taking a subsample of the incurrent fluid in a second subsampler, alternately providing excurrent fluid from the first subsampler to the first gas analyzer and to the second gas analyzer to measure the gas concentrations in the excurrent fluid, and alternately providing incurrent air from the second subsampler to the first gas analyzer and to the second gas analyzer to measure the gas concentrations in the incurrent fluid.

  • Patent number: 8852117
    Abstract: Methods are disclosed for distinguishing whether an animal is experiencing a bacterial infection or a viral infection. One monitors breath taken from the animal over time to measure the relative amount of a first breath stable isotope to a second breath stable isotope therein over time. A quick change in the isotope ratios within several hours from the likely infection is indicative of a bacterial infection. A delayed change in the isotope ratios, followed by periodic repeated alterations in the ratios, is indicative of viral infection. The methods are particularly efficient when using cavity ringdown spectroscopy for the monitoring. They may be used for monitoring a patient already admitted to a hospital, or for monitoring a patient initially complaining of adverse symptoms, or for triage, or for collectively monitoring a population of animals.

  • Patent number: 8844337
    Abstract: An apparatus is presented including an input unit for receiving initial breath samples; a breath analysis module for analyzing the initial breath samples; a comparison module for comparing the initial breath samples to subsequent breath inputs; and a breath authorization module for locking and/or unlocking the apparatus in response to results received from the comparison module. The apparatus may also include a storage unit for storing the initial breath samples and the subsequent breath inputs. The breath analysis module is a chemical breath component analyzer configured to: (i) count each of a plurality of select volatile organic compounds from the initial breath samples and the subsequent breath inputs received from the input unit and (ii) determine a concentration of each of the plurality of the select volatile organic compounds.

  • Patent number: 8822929
    Abstract: A portable breath analyzing device to measure the rate of partial gas that is exhaled in the breath fluid. The device includes a rechargeable power supply unit, a device to emit pulsated infrared radiation, an infrared receiver, and a measuring vessel. The emission device includes a heating element; the measuring vessel includes a metallic tube whose interior surface is polished and coated with a deposit that reflects at least the infrared radiation of wavelengths that are between (9 ?m, 10 ?m) and at each end of the tube, a nozzle comprising a cone-shaped section meant to be placed in the tube axis. The infrared emission device is placed on the longitudinal axis of the tube, at the level of one of the nozzles, and the receiver is placed on the longitudinal axis, at the level of the other nozzle.

  • Patent number: 8795187
    Abstract: A device and a process are provided for recognizing a correct use of an alcohol measuring device by a test subject. At least one alcohol measuring device is provided with a signal transmitter, an analysis and control unit and a camera unit. An image field of the camera unit is divided into an inner image field area and an outer image field area. The inner image field area detects at least the face area of the test subject. The camera unit records changes at a boundary between the inner image field area and the outer image field area. A signal sent by the signal transmitter in the inner image field area can be detected by the camera unit.

  • Publication number: 20140202232
    Abstract: A device for the gas analysis of a gas mixture includes a converter configured to convert a first gas component into a target gas component, a sensor system configured to detect the target gas component or another component of the gas mixture after the conversion by the converter, and an evaluating apparatus. The converter is further configured to change the concentration of a second gas component or to cause a conversion to a second target gas component. The sensor system is configured to determine the concentration of the second gas component or of the second target gas component. The evaluating apparatus is configured to determine a value for the aging of the converter on the basis of the concentration of the second gas component or of the second target gas component.
