Abstract

Systems and methods for electronically monitoring chest sounds and/or sensing electrical cardiac signals such as ECG signals are provided. In one embodiment, a hybrid stethdiographer has a sensing assembly with a chestpiece and a user interface. Stethdiographer also includes a conduit, a power source compartment, a pair of binaurals and a corresponding pair of earpieces. The user interface includes a record button, a mode selector and a display screen. The chestpiece includes a diaphragm and a plurality of electrical cardiac sensors.

Claims

1. A portable hybrid stethdiographer configured to measure chest sounds and cardiac signals, the stethdiographer comprising:

a sensing assembly including a chestpiece and a user interface, wherein the chestpiece includes a diaphragm configured to sense chest sounds from a subject, and wherein the chestpiece also includes a plurality of cardiac sensors configured to sense cardiac signals from the subject;

a conduit configured to transfer the chest sounds from the sensing assembly;

a compartment;

a pair of Y-splits configured to split the chest sounds from the conduit;

a pair of binaurals configured to channel the chest sounds from the Y-splits; and

a pair of earpieces configured to provide chest sounds from the binaurals to a user.

2. The hybrid stethdiographer of claim 1 wherein the compartment is configured to house a power source.

3. The hybrid stethdiographer of claim 1 wherein the cardiac signals are ECG signals.

4. The hybrid stethdiographer of claim 1 wherein the user interface includes a record button, a mode selector, a display screen, a rewind button, a pause button, a fast forward button and a power activator or indicator.

5. The hybrid stethdiographer of claim 4 wherein the display screen is configured to display at least one of the chest sounds and the cardiac signals.

6. The hybrid stethdiographer of claim 1 further comprising a first and a second top cardiac sensors configured to sense additional cardiac signals from at least two fingertips of the subject.

7. The hybrid stethdiographer of claim 6 wherein the additional cardiac signals are ECG signals.

8. The hybrid stethdiographer of claim 6 wherein the display screen is configured to display at least one of the additional cardiac signals.

9. The hybrid stethdiographer of claim 1 further comprising a fingerprint sensor.

10. The hybrid stethdiographer of claim 1 wherein each of the plurality of cardiac sensors includes an insulating cap and an electrode.

11. The hybrid stethdiographer of claim 1 further comprising an internal sound transducer operatively coupled to the diaphragm.

12. The hybrid stethdiographer of claim 1 further comprising an external sound transducer configured to sense ambient sounds thereby providing ambient noise cancellation.

13. The hybrid stethdiographer of claim 12 wherein the external sound transducer is further configured to provide at least one of hands-free dictation, transcription and real-time translation.
