  • Patent number: 12127999
    Abstract: The disclosed CPR devices, systems, and methods adjust a compression depth of a compression mechanism to account for chest collapse of the patient receiving CPR. Compression depth can be adjusted up to a maximum depth in some examples. The compression depth can also be adjusted linearly or non-linearly as the zero point or starting position of the patient's chest changes due to chest collapse. Other factors can also be used to adjust the compression depth such as patient parameters that can be observed by a rescuer or sensed by sensors wirelessly connected to or integrated into the system. CPR devices that include active decompression can also use the disclosed techniques for adjusting the chest compression depth as the patient's chest collapses.

  • Patent number: 11173095
    Abstract: A compression device particularly suited for DVT prophylaxis includes a disposable wrap and a re-usable controller removably mounted on the wrap to apply a tensioning force to the wrap when it is encircling the limb of a patient. The wrap includes an RF chip with a unique identifier and the controller includes an RF sensor and processor to authenticate the wrap before commencing a compression cycle. A kiosk is provided for storing a plurality of wraps for use by patients and a plurality of controllers to be used with any of the wraps. The processor of each controller can control an electric motor in the controller to tighten and loosen the wrap according to a three-stage DVT prophylaxis protocol that produces an optimum blood flow velocity. An accelerometer and software/firmware in the controller can also measure and summarize patient activity while wearing the device.

  • Patent number: 10940324
    Abstract: In embodiments, a WCD system includes electrodes with which it senses an ECG signal of the patient. A processor may detect sequential peaks within the ECG signal, measure durations of time intervals between the peaks, including between non-sequential peaks, and identify a representative duration that best meets a plausibility criterion. The plausibility criterion may be that the representative duration is the one that occurs the most often, i.e. is the mode. Then a heart rate can be computed from a duration indicated by the representative duration and, if the heart rate meets a shock condition, the WCD system may deliver a shock to the patient. An advantage can be that the representative duration can be close to a good R-R interval measurement of a patient, notwithstanding noise in the ECG signal that is in the shape of peaks.
