Abstract
Devices, systems, and methods for non-invasively detecting and monitoring medical conditions using multiple modalities of sensing include at least two electrodes configured to be positioned on a subject, an acoustic sensor configured to be positioned on a subject, a thoracic impedance measurement module connected to the electrodes, for measuring a first impedance between the electrodes, and a heart acoustic measurement module connected to the acoustic sensor, for detecting and measuring a heart sound from the acoustic sensor.
Claims19
A device for non-invasively detecting and monitoring medical conditions, comprising:
- a first electrode pair configured to he positioned on a subject and further configured to measure a disturbance along a first vector;
- a second electrode pair configured to be positioned on the subject and further configured to measure a disturbance along a second vector;
- a sensor configured to be positioned on a torso of the subject and further configured to detect a change in an orientation of the device, the orientation of the device indicating an orientation of the torso of the subject;
- and
- a thoracic impedance measurement module coupled to the first electrode pair and the second electrode pair, wherein the thoracic impedance measurement module is configured to:
- adjust a first frequency of a first current for performance of a first set of impedance measurements and a second frequency of a second current for performance of each impedance measurement of a second set of impedance measurements to scan varying depths of the subject,
- determine the first set of impedance measurements at a first depth of the subject along the first vector and along the second vector when the device is in a first orientation, and
- determine the second set of impedance measurements at a second depth of the subject along the first vector and along the second vector in response to detecting that the orientation of the device has changed from the first orientation to a second orientation,
- wherein physiologic information for the subject is determined based on a change between the first set of impedance measurements and the second set of impedance measurements.
