Abstract
Augmented, virtual, and/or mixed reality applications in optimizing a fitting process and a fit of wearables, including wearable cardioverter defibrillators, to a wearer's body.
Core Innovation
The document describes a problem in long-term wearable cardioverter defibrillator (WCD) electrode placement: improper placement of ECG sensing electrodes leads to noisy ECG signals and poor therapy and data quality. Securement and positioning of both ECG electrodes and defibrillation electrodes on a wearable support structure can be affected over time, resulting in unreliable ECG sensing for energy delivery based on the ECG signal.
The core innovation is an augmented reality fit assist approach for a wearable cardioverter defibrillator system. The system includes a support structure to be worn on a body, an electrocardiogram (ECG) electrode configured to be positioned on and/or over the body, and a defibrillation electrode configured to be positioned on and/or over the body, where energy is discharged via the defibrillation electrode based at least in part on an ECG signal received via the ECG electrode.
The augmented reality fit assist device obtains a position of an internal organ from a database, determines a target position for the ECG electrode based on a history of attire worn by the wearer and the position of the internal organ, and displays an image of the support structure with a superimposed virtual counterpart of the ECG electrode at the indicated target position. The system also includes a processor executing a fitting assistant application, sensors obtaining digital information about physical features of the wearer, and a user interface that displays augmented reality counterparts of WCD elements superimposed over a representation of the physical features.
The device recommends placements of the augmented reality counterparts over the representation based, at least in part, on an internal organ position and a history of attire, with the internal organ position being determined using internal organ imaging.
Claims Coverage
The document includes two independent claims covering 2 inventive features. The first claim covers a WCD system with an augmented reality fit assist device that determines and displays a target ECG-electrode position using an internal organ position from a database and a history of attire. The second claim covers an augmented reality system for optimizing fitting of a WCD by displaying superimposed WCD-element counterparts and recommended placements based on internal organ position and attire history, using sensors and a fitting assistant application executed by a processor.
Augmented reality fit assist for internal organ-based ECG electrode targeting
A wearable cardioverter defibrillator system comprising a support structure, an ECG electrode, a defibrillation electrode, an external wearable cardioverter defibrillator configured to discharge energy based at least in part on an ECG signal received via the ECG electrode, and an augmented reality fit assist device configured to obtain a position of an internal organ from a database, determine a target position for the ECG electrode on the support structure based on a history of attire worn by the wearer and the position of the internal organ, and display an image of the support structure indicating the target position by superimposing a virtual counterpart of the ECG electrode over the image of the support structure.
Augmented reality optimization of WCD fitting via superimposed counterparts and recommended placements
An augmented reality system configured to optimize fitting of a wearable cardioverter defibrillator to a body of a wearer, comprising a support structure, one or more WCD elements, and an augmented reality fit assist device with at least one processor executing a fitting assistant application, at least one sensor obtaining digital information about one or more physical features of the body, and a user interface configured to display one or more augmented reality counterparts of the one or more WCD elements superimposed over a representation of the one or more physical features and further display at least one recommended placement of the one or more augmented reality counterparts based, at least in part, on a position of an internal organ of the wearer and a history of attire worn by the wearer.
Overall claim coverage centers on using augmented reality to indicate or display target or recommended placements of WCD elements, particularly an ECG electrode, on a worn support structure. The placement recommendation is based on internal organ position obtained from a database and, in refinements, internal organ imaging, together with a history of attire, and is presented by superimposing virtual counterparts over a representation of the wearer or the support structure.
