System and method for monitoring the life of a physiological sensor
First Claim
Patent Images
1. A physiological sensor comprising:
- at least one emitter configured to transmit light;
at least one detector configured to detect the light after it has interacted with tissue of a patient and to generate a signal responsive to the detected light; and
a memory device storing information indicating how to calculate a remaining useful life of the sensor, wherein the information assigns a first weighting factor to a first indication of sensor use and assigns a second weighting factor to a second indication of sensor use,wherein the sensor is configured to communicate the information to a separately housed patient monitor that is configured to use at least one of the first weighting factor or the second weighting factor to estimate the remaining useful life of the sensor.

Abstract
Aspects of the present disclosure include a sensor configured to store in memory indications of sensor use information and formulas or indications of formulas for determining the useful life of a sensor from the indications of sensor use information. A monitor connected to the sensor monitors sensor use and stores indications of the use on sensor memory. The monitor and/or sensor compute the useful life of the sensor from the indications of use and the formulas. When the useful life of the sensor is reached, an indication is given to replace the sensor.

10. A patient monitor comprising:
-
an input configured to communicatively couple with a sensor, the sensor comprising an emitter configured to transmit light and a detector configured to detect the light after it has interacted with a tissue site of a patient and to generate a signal responsive to the detected light; and a processor in communication with the input and configured to; obtain, from the sensor, information indicating how to calculate a remaining useful life of the sensor, wherein the information assigns a first weighting factor to a first indication of sensor use and assigns a second weighting factor to second indication of sensor use; and estimate the remaining useful life of the sensor based at least in part on the information and at least one of the first weighting factor or the second weighting factor. - View Dependent Claims (11, 12, 13)
