Abstract
A patient-wearable device for detecting a subpulse of a patient and determining a pulse condition based thereon, and related systems, methods and computer program products. The device includes a base layer comprising a printed circuit board (PCB) and electronics connected thereto, and an adhesive layer connected to the base layer. The electronics may include one or more sensors that generate sensor data, a computer that processes the sensor data to determine the pulse condition of the patient, and a user interface (UI) component that generates a user-perceptible indication of the determined pulse condition. In alternate embodiments, the computer and the UI component may be external to the device and the device may communicate the sensor data to the computer via wired or wireless connection. In further embodiments, multiple devices may be attached to the patient and concurrently transmit raw or processed sensor data to facilitate determination of the pulse condition.
Core Innovation
The invention provides a system for determining a pulse condition of a patient based on detection of a subpulse thereof. The system includes patient-wearable devices attached to body locations of the patient, where the subpulse detection is based on accelerometer-generated sensor data. The subpulse corresponds to a systolic blood pressure less than 60 millimeters of mercury (mmHg), and the accelerometers have sensitivities suitable to detect the subpulse.
In one arrangement, a first patient-wearable device includes at least a first accelerometer and is configured to transmit first sensor data to a computing device via a communication interface. A second patient-wearable device includes at least a second accelerometer and transmits second sensor data to the computing device. The computing device receives the first and second sensor data and processes the sensor data to detect the presence of the subpulse at a first location on the body of the patient and cause a user-perceptible indication of the pulse condition to be generated for presentation to a user.
The system further supports using multiple patient-wearable devices for concurrent sensing at different body locations, with the computing device processing the sensor data by comparing the first sensor data and the second sensor data or by combining the first sensor data and the second sensor data. Processing is configured to detect the presence of the subpulse corresponding to systolic blood pressure less than 60 mmHg, and the detection result is presented to the user via a user interface component that is connected to the computer and controlled thereby.
Claims Coverage
The independent claims are directed to determining a pulse condition of a patient by detecting a subpulse corresponding to systolic blood pressure less than 60 mmHg using accelerometer data from first and second patient-wearable devices at different body locations, and generating a user-perceptible indication based on processed sensor data. Across the independent claims, four main inventive-feature themes appear: (i) multi-location patient-wearable sensing with accelerometers, (ii) sensor-data communication to a computing device, (iii) processing/comparison/combination to detect subpulse presence at a first location, and (iv) generating a user-perceptible indication (including a user interface component).
Two accelerometer-equipped patient-wearable devices at different body locations
A system for determining a pulse condition of a patient based on detection of a subpulse, comprising a first patient-wearable device attachable to a first location on the body and including a first accelerometer, and a second patient-wearable device attachable to a second location on the body different than the first location and including a second accelerometer.
Communication of accelerometer sensor data to a computing device
A system in which at least one communication interface transmits first sensor data generated by the first accelerometer to a computing device and transmits second sensor data generated by the second accelerometer to the computing device, where the computing device receives the first sensor data and second sensor data from the patient-wearable devices.
Processing first and second sensor data to detect subpulse presence corresponding to systolic blood pressure less than 60 mmHg
A computing device configured to process at least the first sensor data and the second sensor data to detect the presence of a subpulse of the patient at the first location on the body of the patient, wherein the subpulse corresponds to a systolic blood pressure less than 60 millimeters of mercury (mmHg), and wherein the first accelerometer and the second accelerometer have sensitivities suitable to detect the subpulse.
Comparison or combination of first and second sensor data for subpulse detection
A processing unit configured to process one or more of a comparison of the first sensor data and the second sensor data or a combination of the first sensor data and the second sensor data in order to process the first sensor data and second sensor data to detect the presence of the subpulse at the first location.
User-perceptible indication of the pulse condition
A system in which the computing device causes a user-perceptible indication of the pulse condition to be generated for presentation to a user, including an arrangement where a user interface component is connected to the computer and controlled thereby to generate the user-perceptible indication.
Across the independent claims, the coverage centers on multi-device, multi-location accelerometer sensing of a subpulse corresponding to systolic blood pressure less than 60 mmHg, transmitting first and second sensor data via communication interfaces to a computing device, processing that data (including by comparing and/or combining) to detect subpulse presence, and generating a user-perceptible indication of the pulse condition.
Stated Advantages
