SENSOR VALIDATION METHOD, PATIENT MONITOR, PHYSIOLOGICAL SENSOR, AND COMPUTER PROGRAM PRODUCT FOR A PATIENT MONITOR
First Claim
1. A method for validating a physiological sensor connected to a patient monitor, the method comprising:
- determining at least one first value respectively for at least one sensor feature parameter indicative of characteristics of a physiological sensor;
storing the at least one first value of each of the at least one sensor feature parameter in a predefined memory location, wherein the determining and storing are performed prior to use of the physiological sensor;
defining, in response to the physiological sensor being connected to a patient monitor, at least one second value respectively for the at least one sensor feature parameter;
retrieving the at least one first value of each of the at least one sensor feature parameter from the predefined memory location;
comparing each of the at least one second value with respective at least one first value; and
deciding, based on the comparing, on acceptance of the physiological sensor.

Abstract
In order to increase sensor manufacturing yield without compromising patient safety, at least one first value is determined respectively for at least one sensor feature parameter indicative of characteristics of a physiological sensor and the determined value(s) is/are stored in a predefined memory location prior to use of a physiological sensor. In response to the physiological sensor being connected to a patient monitor, at least one second value is defined respectively for the at least one sensor feature parameter and the at least one first value of each of the at least one sensor feature parameter is retrieved from the predefined memory location. Each of the at least one second value is compared with respective at least one first value and a decision is made, based on the comparison, on the acceptance of the physiological sensor.
