  • Patent number: 10278606
    Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.

  • Patent number: 10111621
    Abstract: A conductive lead that connects a medical sensor or probe to a monitoring or analytical machine. The conductive lead is flexible, lightweight and can be manufactured at a very low cost. The conductive lead has a dielectric flexible substrate. Conductive ink is printed upon the flexible substrate. The conductive ink forms contact pads and connection lines on the flexible substrate. The connection lines electrically interconnect the various conductive pads. An insulation layer covers the connection lines The insulation layer can be dialectic ink that is printed atop the conductive ink. Peel-away protective covers are used to cover the contact pads. Any one of the contact pads can be exposed for use by removing the protective cover that covers it. The contact pads are used to electrically interconnect with both the sensor and the machine.

  • Patent number: 10105101
    Abstract: A biomedical sensor has conducting elements disposed at least partly over a skin-facing surface. A sensing element detects a signal representative of a physiological parameter of a body using the conducting elements. A storage device stores a physiological model. A processor determines sensor placement quality by comparing the signal to the model and operates an indicator to indicate the determined quality. A method of measuring using the sensor includes computing a measurement acceptance criterion using numerous measurements, determining whether a subsequent test measurement corresponds to the measurement acceptance criterion obtained from the computing step, and indicating the results via the indicator. A system for measuring a physiological property of the body includes the sensor, a user interface device to receive measurements from the sensor, and a processor associated with the user interface device and configured to provide feedback if the measurement does not meet a selected acceptance criterion.

  • Patent number: 10092200
    Abstract: A plethysmograph variability processor inputs a plethysmograph waveform having pulses corresponding to pulsatile blood flow within a tissue site. The processor derives plethysmograph values based upon selected plethysmograph features, determines variability values, and calculates a plethysmograph variability parameter. The variability values indicate the variability of the plethysmograph features. The plethysmograph variability parameter is representative of the variability values and provides a useful indication of various physiological conditions and the efficacy of treatment for those conditions.

  • Patent number: 10085663
    Abstract: An ECG system identifies and annotates cardiac electrophysiological signals in an ECG waveform from harmonic waveforms. Electrical impulses are received from a beating heart. The electrical impulses are converted to an ECG waveform. The ECG waveform is converted to a frequency domain waveform, which, in turn, is separated into two or more different frequency domain waveforms, which, in turn, are converted into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms. The plurality of subwaveforms and discontinuity points are compared to a database of subwaveforms and discontinuity points for normal and abnormal patients. At least one subwaveform or one or more discontinuity points are identified as a normal or abnormal electrophysiological signal of the ECG waveform from the comparison. The ECG waveform is displayed along with one or more markers at a location of the at least one subwaveform or one or more discontinuity points.

  • Patent number: 10076257
    Abstract: This is directed to an electronic device having an integrated sensor for detecting a user's cardiac activity and cardiac electrical signals. The electronic device can include a heart sensor having several leads for detecting a user's cardiac signals. The leads can be coupled to interior surfaces of the electronic device housing to hide the sensor from view, such that electrical signals generated by the user can be transmitted from the user's skin through the electronic device housing to the leads. In some embodiments, the leads can be coupled to pads placed on the exterior of the housing. The pads and housing can be finished to ensure that the pads are not visibly or haptically distinguishable on the device, thus improving the aesthetic qualities of the device. Using the detected signals, the electronic device can identify or authenticate the user and perform an operation based on the identity of the user.
