Embodiment Construction

[0033] As described herein, this invention provides systems and methods for acquiring body sound information from a person's ear, which can then be converted to useful physiological parameters of interest, such as heart rate, heart valve closure timing, pulse wave velocity, blood pressure, and the like.

[0034] FIGS. 1A and 1B show one exemplary embodiment of a system 100 according to this invention in which internally generated body sounds are detected or measured using an ear sensor device 110 inserted into the ear of a person. As shown in FIGS. 1A-1B, the ear sensor or ear sensing device 110 includes an ear plug housing 124, a sensor element 114 disposed within a portion of the ear plug housing 124, an acoustic shield 112 and a preamplification circuit 116 electrically coupled to sensor element 114 via electrical connections 118. The purpose of the acoustic shield 112 is to shield the sensor element 114 from ambient noise generated outside the person's body. The preamplification ci...

Abstract

Methods and systems for determining physiological parameters from body sounds obtained from a person's ear. In various exemplary embodiment, the system includes an earplug housing; a sensing element disposed within a portion of the earplug housing; an acoustic shield coupled to the earplug housing, the acoustic shield reducing or eliminating extracorporeal sounds; and a preamplification circuit electrically coupled to the sensing element. In various exemplary embodiments, the system is operable to determine motion and/or vibration of the external acoustic meatus or the tympanic membrane of the ear due to internally generated body sounds.

Description

[0001] 1. Field of Invention[0002] This invention relates to systems and methods for detecting and / or measuring a person's physiological parameters by detecting the person's internally generated body sounds, such as heart sounds, at a location within a person's ear, and processing the measured body sounds to obtain physiological parameters of interest.[0003] 2. Description of Related Art[0004] Sound signals recorded from the heart are called phonocardiogram (PCG) signals. A healthy heart generates two distinct sounds that are coincident with the closure of the heart valves. These two sounds are called the first heart sound (S1) and the second heart sound (S2). In particular, S2 is coincident with the closure of the aortic valve. The closure of the aortic valve also creates a distinct feature on the arterial blood pressure waveform called the dicrotic notch. The pulse transit time (PTT) is defined as the time required for an arterial blood pressure pulse to travel from the heart to a...
