  • Patent number: 11058324
    Abstract: Apparatuses are described to accurately determine a gas concentration of a sample of a patient's breath. The apparatuses may include a sample compartment, a breath speed analyzer, a gas analyzer, and a processor. The sample compartment includes an inlet that receives the breath. The breath speed analyzer determines the speed of a portion of the breath. The gas analyzer determines a gas concentration. The processor includes an algorithm that determines a degree of non-homogeneity of the sample based on the speed, and a corrected gas concentration based on the degree of non-homogeneity. In some variations, the gas correction is determined independently of patient cooperation. Apparatuses may be tuned based on the intended population's expected breathing pattern ranges such that the sample compartment is filled with a homogenous end-tidal gas sample regardless of an individual's breathing pattern. These apparatuses are useful, for example, for end-tidal CO analysis. Methods are also described.

  • Patent number: 11033202
    Abstract: Methods and systems to determine the lung clearance index (LCI) or other indices of ventilation inhomogeneity of lungs of a paediatric subject are provided. Inert tracer gas is washed-in and the wash-out is conducted by inhaling atmospheric air from the surroundings and exhaling to a confined space until the end-tidal tracer gas concentration has fallen below a predetermined fraction of the starting concentration. The LCI is calculated as the ratio between the cumulative expired volume (VCE) required to clear the inert tracer gas concentration from the lungs below a predetermined fraction of the starting concentration and the functional residual capacity (FRC) determined by dividing the net volume of inert tracer gas exhaled with the difference in end-tidal fractional concentration of the inert tracer gas at the start and end of the wash-out period; where VCE is determined by measuring the total volume in the collection bag after completed wash-out period.

  • Patent number: 10918329
    Abstract: Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patient's airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14, 16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.

The system may also estimate the contributions of specific confounding substances, and/or the contributions of other factors or events (such as exercise, interrupted sleep, a missed medication, etc.) that affect ketone levels. Another feature involves the generation and display of target ketone levels that are personalized for the participants. The system may generate the measurement breakdowns and target ketone levels by applying data mining algorithms to aggregated data of many program participants.

The method includes the steps of mapping the data array onto a 2-dimensional array, decomposing the 2-dimensional array and forming a signature of the subject 104 from the decomposed 2-dimensional array representing a motion pattern.

  • Patent number: 10342456
    Abstract: An apparatus and method is provided for analyzing a breathing gas flowing along a breathing tubing for subject breathing. The breathing gas comprises breathing cycles having different phases. Liquid particles can be delivered intermittently depending on the phase, or continuously into the breathing gas. The apparatus comprises a gas sample supplier for adjusting gas sample supply from the breathing gas, and a gas analyzer for receiving the gas sample adjusted by the gas sample supplier and for measuring the gas sample property. The apparatus further comprises a processing unit for receiving a signal indicative of one of the phases of the breathing cycle and the delivery timing of the liquid particles. The processing unit is able to control the sample supplier based on the signal to limit access of liquid particles with the gas sample towards the gas analyzer.

  • Patent number: 10251581
    Abstract: Devices and methods for measuring and quantifying airflow through the adult human nose by detecting and measuring the amount of moisture condensate in contact with a pair of flat surfaces or substrates positioned beneath the patient's nose for a predetermined length of time, usually about three (3) seconds. The device comprises a microprocessor, a memory, an output device and a moisture sensing unit. The moisture sensing unit, comprising twin left and right detectors, produces output signals representative of the amounts of moisture condensate in contact with the left and right detectors, respectively. The microprocessor determines the volume density, current density, or relative humidity density from a series of measurements of the condensation as it propagates and decays during exhalation. The microprocessor stores the results in the memory and transmits the data, as well as calculated nasal condition information, to the output device, preferably a digital display.

  • Patent number: 10244198
    Abstract: A system for testing an individual for illicit or other substances is described. The system operates in tandem with a mobile device (smartphone) application, which employs a camera of the mobile device to capture and record the self-administered specimen collection process for verification and rule compliance. The system guides the user through the process via on-screen prompts on the mobile device, and includes tracking of the collected specimen from the moment of collection until it is sealed in a tamper-proof container to be mailed for external testing at a lab. A breathalyzer may also be used with the system to test for the presence of alcohol in the user's body, the use of which is also monitored and recorded via the on-board camera of the mobile device for verification.

  • Patent number: 10188295
    Abstract: Methods and systems for an integrated sensor network are described. In one embodiment, sensor data may be accessed from a plurality of motion sensors and a bed sensor deployed in a living unit for a first time period. An activity pattern for the first time period may be identified based on at least a portion of sensor data associated with the first time period. The activity pattern may represent a physical and cognitive health condition of a person residing in the living unit. Additional sensor data may be accessed from the motion sensors and the bed sensor deployed for a second time period. A determination of whether a deviation of the activity pattern of the first time period has occurred for the second time period may be performed. An alert may be generated based on a determination that the derivation has occurred. In some embodiments, user feedback is captured on the significance of the alerts, and the alert method is customized based on this feedback. Additional methods and systems are disclosed.
