Abstract
Disclosed herein are methods and apparatus including medical devices having features for monitoring sounds and motions indicative of a state of health or administration of CPR to a subject. In one embodiment, a therapeutic device such as a therapy electrode comprises a layer configured to deliver a therapy to a subject and an acoustic sensor on the therapeutic device and coupled to the layer.
Claims35
A therapeutic device comprising:
- a therapy electrode comprising:
- a substrate;
- a conductive layer disposed on a lower surface of the substrate and configured to deliver a therapy to a subject;
- and
- an acoustic sensor disposed within the therapy electrode and mechanically coupled to the conductive layer, the acoustic sensor configured to acoustically couple to a body of a subject to which the therapy electrode is applied, the acoustic sensor comprising
- a multi-channel accelerometer,
- wherein a first channel of the multi-channel accelerometer is configured to monitor sounds produced by a heart of the subject, and
- a second channel of the multi-channel accelerometer is configured to monitor at least one additional parameter associated with a state of the subject, the at least one additional parameter including one or more of a parameter associated with respiration of the subject, gastrointestinal sounds of the subject, snoring of the subject, body position of the subject, and body movement of the subject.

A medical device assembly comprising:
- a substrate;
- a layer disposed on the substrate, the layer forming a therapeutic device portion of the medical device assembly, the layer having a first surface configured to be placed adjacent a patient's skin and to selectively apply a therapy to the patient in response to an activation signal;
- and
- an acoustic sensor acoustically coupled to the layer, the acoustic sensor including a multi-channel accelerometer, a first channel of the multi-channel accelerometer being configured to monitor sounds produced by a heart of the patient, and a second channel of the multi-channel accelerometer being configured to monitor at least one additional parameter associated with a state of the patient, the at least one additional parameter including one or more of a parameter associated with respiration of the patient, gastrointestinal sounds of the patient, snoring of the patient, body position of the patient, and body movement of the patient.
1 more element
A therapeutic device comprising:
- a therapy electrode including:
- a substrate;
- a conductive layer disposed on a lower surface of the substrate;
- an electrically conductive gel reservoir configured to release an electrically conductive gel onto a surface of the conductive layer;
- and
- an acoustic sensor disposed within the therapy electrode and configured to acoustically couple to a body of a subject to which the therapy electrode is applied, the acoustic sensor being acoustically coupled to the conductive layer through a cap housing the conductive gel reservoir.
