SENSOR SYSTEM
First Claim
1. A sensor system for determining a pulse transit time measurement of a patient, the sensor system comprising:
- a carotid sensor device configured to be positioned on a neck of the patient over a carotid artery of the patient, the carotid sensor device being configured to detect a plethysmograph waveform from the carotid artery; and
a temporal sensor device operatively connected to the carotid sensor device, the temporal sensor device being configured to be positioned on the patient over a temporal artery of the patient, wherein the temporal sensor device is configured to detect a plethysmograph waveform from the temporal artery.

Abstract
A sensor system is provided for determining a pulse transit time measurement of a patient. The sensor system includes a carotid sensor device configured to be positioned on a neck of the patient over a carotid artery of the patient. The carotid sensor device is configured to detect a plethysmograph waveform from the carotid artery. The sensor system includes a temporal sensor device that is operatively connected to the carotid sensor device. The temporal sensor device is configured to be positioned on the patient over a temporal artery of the patient. The temporal sensor device is configured to detect a plethysmograph waveform from the temporal artery.

15. A method for determining a pulse transit time of a patient using a sensor system, the method comprising:
-
affixing a carotid sensor device to a neck of the patient over a carotid artery of the patient; affixing a temporal sensor device to the patient over a temporal artery of the patient; detecting a plethysmograph waveform from the carotid artery of the patient using the carotid sensor device; detecting a plethysmograph waveform from the temporal artery of the patient using the temporal sensor device; and determining the pulse transit time measurement based, at least in part, on the plethysmograph waveforms from the carotid and temporal arteries. - View Dependent Claims (16, 17, 18, 19)

20. A temporal sensor device comprising:
-
a housing comprising an internal compartment and a temporal segment, the housing comprising an ear clip that is configured to wrap around the base of an ear of a patient such that the temporal segment of the housing is positioned over a temporal artery of the patient; and a sensor held within the internal compartment of the housing at the temporal segment of the housing such that the sensor is configured to detect a plethysmograph waveform from the temporal artery when the ear clip is wrapped around the base of the patient'"'"'s ear.
