  • Publication number: 20140213878
    Abstract: The invention provides an electrode and associated electrode holder that are used for physiological measurements, e.g. measurements of signals that can be processed to generate ECG and TBI waveforms. The electrode and electrode holder connect to each other using a magnetic interface. In embodiments, for example, the magnetic interface includes oppositely polled magnets integrated in both the electrode and electrode holder. The magnets are typically rare earth magnets coated with a thin, electrically conductive metal film. This way, when the magnets come in contact with each other, the metal films touch to form both a mechanical and electrical connection. Thus the magnetic interface can replace conventional mechanisms used to connect rivet-based electrodes to leads, which are typically used to secure electrodes for physiological measurements.

  • Patent number: 8626260
    Abstract: An expandable electrode pad having a flexible and stretchable base member that may be either expanded or compressed to provide proper positioning for a plurality of electrode distal contacts. Portions of the base member may have perforations that allow one or more sections of the base member to be separated and positioned a greater, non-stretchable distance away from the remaining strip of distal contacts. Additionally, the circuit body may comprise a distal cut zone that provides for freedom of movement of the plurality of distal contacts and a proximal perforated zone that eliminates lead wire entanglements while also allowing for the tearing of perforations between adjacent conductive circuits when a greater reach is required for the proper placement of a distal contact.

    Abstract: The present invention relates to electrocardiography and to electrode arrangements used in electrocardiographic monitoring devices. An EKG patch may include a plurality of individual EKG patches, each comprising a base layer and a plurality of electrodes capable of receiving an electrical signal generated by the myocardium of a human heart. Each of the plurality of the individual EKG patches may be stacked on top of each other such that each electrode in an individual patch aligns and contacts with at least one corresponding electrode in an adjacent EKG patch, thereby allowing a free flow of electricity through the plurality of stacked EKG patches, and such that the bottom-most EKG patch may be contacted with the skin of a patient. A temporary or release adhesive may be placed between each of the plurality of EKG patches such that the bottom-most EKG patch may be peeled away from the stack after each use.

    Abstract: In certain variations, methods, systems and/or devices for enhancing conductivity of an electrical signal through a subject's skin using one or more microneedle electrodes are provided. A microneedle electrode may be applied to the subject's skin by placing the microneedle electrode in direct contact with the subject's skin. The microneedles of the microneedle electrode may be inserted into the skin such that the microneedles pierce stratum corneum of the skin up to or through dermis of the skin. An electrical signal passes or is conducted through or across the microneedle electrode and the subject's skin, where impedance of the microneedle electrode is minimal and greatly reduced compared to existing technologies.

  • Publication number: 20130296680
    Abstract: A method for identifying a target arrhythmia, for example, atrial fibrillation, with very high specificity includes obtaining heart rhythm data such as EKG data, selecting and analyzing a segment of the data for arrhythmia, if an arrhythmia is found then reanalyzing the segment of data for a hidden regularity that would indicate the data is not the target arrhythmia. If no hidden regularity is found, then identifying the segment as the target arrhythmia.

  • Publication number: 20130274584
    Abstract: Systems and methods for management of physiological data, for example data obtained from monitoring an electrocardiogram signal of a patient. In one example use, digital data is obtained and episodes of arrhythmias are detected. Snapshots of the digitized ECG signal may be stored for later physician review. One or more techniques may be used to avoid recording of redundant data, while ensuring that at least a minimum number of episodes of each detected arrhythmia can be stored. The system may automatically tailor its data collection to the cardiac characteristics of a particular patient. In one technique, memory is allocated to include for each detectable arrhythmia a memory segment designated to receive ECG snapshots representing only the respective arrhythmia. A shared memory pool may receive additional snapshots of as the designated memory segments fill.
