Abstract
The present disclosure relates to a wearable device and systems/methods relating to the device. Certain embodiments may include two flexible wings and a bridge connecting the two wings. In some embodiments, the upper surface of the bridge can be non-adhesive and uncoupled to the flexible wing such that the flexible wing can be decoupled from the bridge when the adhesive is adhered to the surface of a user.
Core Innovation
The disclosure describes a wearable physiological monitoring patch that includes a housing and a wing extending from the housing. The wing comprises an electrode configured to detect a physiological signal of a user, with the electrode in electrical communication with the hardware processor. The wing is configured to conform to a surface of the user to support long-term conformal monitoring.
The wearable device includes an adhesive layer coupled to a bottom surface of the wing, where the adhesive layer is configured to adhere the wearable device to the user. A substrate layer overlies the adhesive layer and includes a plurality of apertures extending from a bottom surface of the substrate layer to a top surface of the substrate layer, with the apertures configured to transport moisture from the surface of the user. Individual apertures overlie individual continuous portions of the adhesive layer to coordinate moisture transport and adhesion.
The disclosure further describes moisture-management and motion-artifact reduction concepts, including moisture transpiration features such as channels and apertures, optional moisture wicking materials, and flexible hinge regions that allow a non-adhered or “floating” housing portion. The flexible wing and housing are described as supporting conformal contact with moisture drainage to improve long-term wear performance. Modular or replacement concepts are also described for adhesive and flexible components, alongside clinical analysis platforms that selectively transmit and triage ECG data for cardiac rhythm inference.
Claims Coverage
The partial content provides two independent claims (a monitoring device claim and a method claim). Across these independent claims, the inventive focus is on a conformal wing with an electrode for physiological detection combined with a moisture-transport substrate having apertures positioned over continuous adhesive portions.
A moisture-transport adhesive-backed conformal monitoring wing
A monitoring device configured to attach to a user, comprising a housing comprising a hardware processor; a wing extending from the housing and configured to conform to a surface of a user, the wing comprising an electrode configured to detect a physiological signal of the user, the electrode in electrical communication with the hardware processor; an adhesive layer coupled to the bottom surface of the wing, the adhesive layer configured to adhere the wearable device to the user; a substrate layer positioned over the adhesive layer, the substrate layer comprising a plurality of apertures extending from a bottom surface of the substrate layer to a top surface of the substrate layer, the apertures configured to transport moisture from the surface of the user; and wherein individual apertures overlie individual continuous portions of the adhesive layer.
A method of monitoring with a device having apertures over continuous adhesive portions
A method of monitoring physiological signals, comprising attaching a monitoring device to a user, the monitoring device comprising a housing comprising a hardware processor; a wing extending from the housing, the wing comprising an adhesive layer coupled to a bottom surface of the wing; a substrate layer overlying the adhesive layer, the substrate layer comprising a plurality of apertures extending from a bottom surface of the substrate layer to a top surface of the substrate layer, the apertures configured to transport moisture from the surface of the user, and wherein individual apertures overlie individual continuous portions of the adhesive layer; and collecting physiological data from the user.
In the provided independent claims, the core coverage centers on combining a conformal electrode-bearing wing with an adhesive layer and a substrate having apertures that transport moisture, where each aperture overlies a continuous adhesive portion. The method claim mirrors this architecture by requiring attachment of such a device before collecting physiological data.
Stated Advantages
Supports long-term conformal ECG monitoring.
Designed to manage moisture at the interface via moisture transpiration through channels/apertures and transport from the user surface.
Flexible hinge regions with a non-adhered or “floating” housing portion are described to reduce peel and motion artifact.
Selective transmission and triage of ECG data using detection and filtering criteria is described to obtain clinically relevant rhythm onset/offset events while reducing power/battery impact.
Documented Applications
Selective transmission and triage of ECG data using R-peak/QRS detection to obtain rhythm onset/offset events.
Cloud/server-side cardiac rhythm inference from an R-R interval time series, optionally using accelerometer/activity and ECG features, with confidence-score-based filtering.
