Abstract
In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one electrocardiogram (ECG) electrode, at least one acoustic sensor, and at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one therapy electrode. The at least one processor can receive at least one acoustic signal from the at least one acoustic sensor, receive at least one electrode signal from the ECG electrode, detect at least one unverified cardiopulmonary anomaly using the at least one electrode signal, and verify the at least one unverified cardiopulmonary anomaly with reference to data descriptive of the at least one acoustic signal.
Core Innovation
An ambulatory medical device is configured to be worn on a body of a patient and includes at least one ECG electrode, at least one acoustic sensor configured to detect one or more sounds indicative of a state of health of the patient, and at least one motion sensor configured to detect motion of the patient. A processor receives at least one ECG signal, at least one acoustic signal, and at least one motion signal, and transmits the signals to a remote system for identification of sleep apnea in the patient.
The identification of sleep apnea is based on analysis of the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal, and the analysis includes an analysis of at least a strength of an S3 sound from the at least one acoustic signal. The device architecture includes receiving and processing the multi-signal inputs and transmitting them to a remote system via a network interface.
The acoustic sensor and the motion sensor are implemented as part of the wearable device, with embodiments where the sensors are mechanically coupled to a garment worn by the patient, including a torso garment. The wearable configuration supports sensing of health-indicative sounds and patient motion while enabling the remote system to perform the sleep apnea identification using the S3 sound strength and the combined ECG and motion signals.
Claims Coverage
The document includes three independent claims. Across these, the inventive coverage centers on combined wearable ECG sensing, acoustic sound sensing with S3 sound strength, and motion sensing, transmitted to a remote system/server to identify sleep apnea.
Ambulatory multi-sensor wearable for remote sleep apnea identification
An ambulatory medical device configured to be worn on a body of a patient, comprising at least one ECG electrode, at least one acoustic sensor, at least one motion sensor, and a processor to receive ECG, acoustic, and motion signals and transmit the signals to a remote system for identification of sleep apnea based on analysis of the ECG signal, the acoustic signal, and the motion signal, wherein the analysis includes an analysis of at least a strength of an S3 sound from the acoustic signal.
Networked medical system with server-side sleep apnea identification
A medical system comprising a server and a medical device with a first network interface, at least one ECG electrode, at least one acoustic sensor, at least one motion sensor, and a processor configured to receive ECG, acoustic, and motion signals and transmit the acoustic signal, the ECG signal, and the motion signal to the server via the first network interface for identification of sleep apnea based on analysis of the acoustic signal, the ECG signal, and the motion signal, wherein the analysis includes an analysis of at least a strength of an S3 sound from the acoustic signal, and wherein the server comprises a second network interface configured to receive the signals from the medical device.
Non-transitory medium for combined-signal sleep apnea identification using S3 strength
A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform a method to identify sleep apnea in a patient by receiving at least one acoustic signal, receiving at least one ECG signal, receiving at least one motion signal, and transmitting the acoustic signal, the ECG signal, and the motion signal to a remote system for identification of sleep apnea based on analysis of the acoustic signal, the ECG signal, and the motion signal, wherein the analysis includes an analysis of at least a strength of an S3 sound from the acoustic signal.
Overall, the independent claims are directed to using a wearable ambulatory device that acquires ECG, acoustic signals, and motion signals, and transmits them to a remote system/server to identify sleep apnea.
