Patent Images
1. A system which uses a light emitter and an optical detector to determine a condition of a patient and electronically transmit an audio or visual indication to alert a care provider about the condition of the patient, the system comprising:
- a first disposable adhesive attachment component, utilizing an adhesive attachment mechanism, configured to attach to a measurement site of the patient;
a reusable component including a light emitter and a light detector, the reusable component configured to attach to the first disposable adhesive attachment component, the reusable component configured to emit at least a plurality of wavelengths of light into a portion of the patient'"'"'s body and detect the emitted light reflected from the patient;
a processor configured to monitor a characteristic of the patient to determine the condition of the patient, the processor configured to process the detected light to determine a change in a magnitude of the detected light which does not correlate to a change in a physiological blood parameter, wherein based on the processing, the processor also determines if the condition affecting the patient should be communicated to a healthcare provider; and
a display device configured to communicating the condition affecting the patient to a care provider using either an audio or visual indication.

Abstract
An optical based patient monitoring system employing an optical sensor and providing an indication of an optical change which does not correlate to a change in a physiological blood parameter and based on that indication, providing a care provider an indication of a condition of a patient. The optical based patient monitoring system providing the indication of the patient condition in relation to a patient using an IV setup.

14. A method of detecting a change in light absorption characteristics at a measurement site of a patient, the change being unrelated to a physiological blood parameter of a patient, the method comprising:
-
providing a first disposable adhesive attachment component, the first disposable adhesive attachment component having an adhesive attachment mechanism and configured to attach to a measurement site of a patient; providing a second reusable component configured to couple to the first disposable adhesive attachment component, the reusable component configured to emit at least a plurality of wavelengths of light into a portion of the patient'"'"'s body and receive the emitted light reflected from the patient; and determining, using a hardware processor a condition affecting the patient based on the received light reflected from the patient; determining, using the hardware processor that a change in light absorption has occurred that is not related to a change in a composition of arterial blood of the patient; providing an indication alerting a care provider of a condition of a patient. - View Dependent Claims (15, 16, 17, 18, 19)
