  • Patent number: 11813399
    Abstract: Various implementations include a CPAP alarm system that generates an alarm when the concentration of CO2 is less than a certain threshold. The threshold may represent a minimum concentration of CO2 that is expected to be expelled from the patient. Other implementations are directed to a CPAP apparatus that can couple the CPAP alarm system to a CPAP air delivery device. The CPAP apparatus includes a support body that can be coupled to the CPAP air delivery device and that supports the CPAP alarm system outside of the air delivery device. A CO2 concentration sensor of the CPAP alarm system can be disposed on the apparatus such that the flow of CO2 from a breathing patient is directed toward the CO2 concentration sensor when the CPAP air delivery device is in use and is in the proper position for the patient.

  • Patent number: 11077857
    Abstract: A device for controlling alcohol interlock according to an embodiment of the present disclosure includes a sensor for obtaining position information and breath information of a fellow passenger, and a controller that determines whether a blood alcohol concentration of the fellow passenger is measured based on the position information and the breath information of the fellow passenger, and determines whether to re-measure a blood alcohol concentration based on the determination result. Thus, the device may prevent surrogate measurement of the fellow passenger, so that a driver's own blood alcohol concentration may be measured accurately, and drunk driving of a driver may be fundamentally prevented.

  • Patent number: 9204821
    Abstract: An upper respiratory bacterial infection is detected from exhaled mammalian breath by using a colorimetric sensor array having a spectral response characteristic that changes when exposed to bacteria-produced analytes in the exhaled breath. A flow regulating system directs a leading portion of the exhaled breath into gaseous communication with the array to change its spectral response characteristic, and discharges a trailing portion of the exhaled breath exteriorly of the apparatus. A spectral analysis system analyzes the spectral response characteristic changed solely by the leading portion of the exhaled breath, and detects the upper respiratory bacterial infection when the bacteria-produced analytes are present therein. Reactivity of the analytes with the array is increased by advance oxidizing and/or heating the analytes.

    Abstract: Continuous measurement of breathing impedance with extremely high precision is enabled by executing noise elimination. A loudspeaker applies an air vibration pressure by an oscillation wave to an oral cavity, the oscillation wave being obtained by frequency-cuffing so executed that the oscillation wave has only the frequency component that is left after the culling is executed from a plurality of different frequencies and being generated by a pulse signal for pulse drive with pulses made positive and negative separately in correspondence to the time of exhalation and the time of inhalation. A pressure inside the oral cavity is detected and a breathing flow is detected, and a signal obtained by the detection is Fourier-transformed to obtain a spectrum. Analysis of the spectrum is performed to obtain breathing impedance.

    Abstract: A cardiac rhythm management (CRM) device can extract ventilation information from thoracic impedance or other information, and adjust a delivery rate of the CRM therapy. A tidal volume of a patient is measured and used to adjust a ventilation rate response factor. The measured tidal volume can optionally be adjusted using a ventilation rate dependent adjustment factor. The ventilation rate response factor can also be adjusted using a maximum voluntary ventilation (MVV), an age predicted maximum heart rate, a resting heart rate, and a resting ventilation determined for the patient. In various examples, a global ventilation sensor rate response factor (for a population) can be programmed into the CRM device, and automatically tailored to be appropriate for a particular patient.

This integrated condenser includes an outer surface region on a sampler surface that facilitates condensing at least a component in a received gas-phase sample into liquid-phase droplets on the sampler surface, and aggregating and moving the condensed droplets radially toward an inner surface region on the sampler surface that receives the condensed droplets. For example, the outer surface region may include a set of micro-patterned concentric rings, each of which includes a set of radially oriented wall-groove pairs. Moreover, the sampler surface may be increasingly less hydrophobic along a radial direction toward the center of the sampler surface, thereby creating an axisymmetric wettability gradient.

    Abstract: Vital sign monitoring is especially challenging in small animals, given the high metabolic rates and small volumes under consideration. An embodiment of the present invention includes a unique nose-cone design and associated instrumentation which allows for measurement of respiratory parameters, including anesthesia gas concentration, inspiratory and expiratory O2, and inspiratory and expiratory CO2 (capnometry). Such instrumentation facilitates a physiologic assessment of small animals undergoing general anesthesia, an increasingly important consideration as small animals play a greater role in in vivo biomedical studies. In addition, the techniques proposed herein are suitable for measurement on small respiratory volumes associated with neonatal monitoring.

  • Publication number: 20140039339
    Abstract: An endoscopic bite block, with teeth position defining regions which guide the subject's teeth to grip the bite block in their natural position, with the teeth of the upper jaw positioned further out than the lower jaw teeth. These teeth position defining regions are also preferably curved to match the curved shape of the jaw. The upper and lower parts of the front plate of the bite block may also be positioned at different distances out, so that upper and lower lip regions both contact the front plate snuggly. The bite block may be used with separate oral/nasal cannulae, or may incorporate breath sampling or gas supply cannulae. A flexible flapped curtain at the outer end of the bite block may be provided to largely enclose the inner volume of the bite block to enable more accurate capnographic sampling under conditions of wide-open mouth breathing.
