Opticoustic sensor
First Claim
1. A physiological sensor comprising:
- an optic assembly comprising an optic transducer;
an acoustic assembly comprising an acoustic transducer;
an attachment assembly configured to affix the optic assembly and acoustic assembly to a tissue site at a neck of a patient, the attachment assembly comprising;
an elongated body comprising a first section including a first wing of the elongated body, a second section including a second wing opposite the first end of the elongated body, and a third section between the first wing and the second wing, the third section including a center of the elongated body, the first wing having a length greater than a width, wherein the width of the first wing adjoins the first wing to the third section, the first wing extending in a first direction away from the third section and the second wing having a length greater than a width, wherein the width of the second wing adjoins the second wing to the third section, the second wing extending in a second direction, opposite the first direction, away from the third section;
wherein the acoustic assembly is affixed to the third section and the optic assembly is affixed to the first wing;
the optic transducer configured to transmit a plurality of wavelengths of light into the tissue site and detect the light after attenuation by pulsatile blood flow within the tissue site so as to generate an optic signal;
the acoustic transducer configured to respond to vibrations at the surface of the tissue site so as to generate an acoustic signal; and
a sensor cable configured to transmit the optic signal and the acoustic signal, the sensor cable further configured to connect to a monitor configured to calculate a plurality of physiological parameters based on the transmitted optic and acoustic signals.

Abstract
A physiological sensor has an optic assembly, an acoustic assembly and an attachment assembly. The optic assembly has an optic transducer that is activated so as to transmit a plurality of wavelengths of light into a tissue site and to detect the light after attenuation by pulsatile blood flow within the tissue site. The acoustic assembly has an acoustic transducer activated so as to respond to vibrations at the surface of the tissue site. The attachment assembly affixes the optic assembly and acoustic assembly to the tissue site, such as along one side of a person'"'"'s neck or the forehead. A sensor cable extends from the attachment assembly so as to transmit an optic transducer signal and an acoustic transducer signal to a monitor for calculation of physiological parameters.
