Systems and methods for storing data on medical sensors

Abstract

A system includes a monitor configured to be coupled to multiple sensors over time to monitor one or more physiological characteristics of one or more patients. A first sensor of the multiple sensors includes a sensor memory, and the monitor is configured to transfer information to the first sensor for storage in the sensor memory of the first sensor. The information includes information related to one or more sensors of the multiple sensors that were coupled to the monitor prior to the first sensor.

What is claimed is: 
     
         1 . A system, comprising:
 an information collection system, comprising:   a monitor configured to be coupled to multiple sensors over time to monitor one or more physiological characteristics of one or more patients;   a first sensor comprising a sensor memory; and   a database,   wherein the monitor is configured to receive sensor identifying information from the first sensor,   wherein the information collection system is configured to store in the database unique sensor identifying information and information related to sensor design or sensor use of the first sensor.   
     
     
         2 . The system of  claim 1 , wherein the sensor identifying information includes sensor serial number information. 
     
     
         3 . The system of  claim 1 , wherein the monitor is configured to transmit monitor identifying information to the sensor. 
     
     
         4 . The system of  claim 1 , wherein the information collection system is configured to detect later use of the same, particular sensor. 
     
     
         5 . The system of  claim 4 , wherein the database stores information related to serial numbers of plural sensors coupled with a monitor. 
     
     
         6 . The system of  claim 1 , wherein the database sorts data at least according to sensor serial number. 
     
     
         7 . The system of  claim 1 , wherein the database provides identification of duplicate data, inclusive of serial number, for a particular sensor. 
     
     
         8 . The system of  claim 1 , wherein the sensor transmits sensor identifying information to the monitor upon coupling with the monitor. 
     
     
         9 . The system of  claim 1 , wherein the monitor couples with plural different sensors, each of which provides sensor serial number information to the monitor, which is stored in the database. 
     
     
         10 . The system of  claim 9 , wherein plural sensor serial numbers and monitor identifying information are stored in the database. 
     
     
         11 . The system of  claim 1 , wherein the database information comprises a duration of operation of each sensor of the one or more sensors, an indication of compatibility between each sensor of the one or more sensors and the monitor, a number of alarms generated during operation of each sensor of the one or more sensors, a number of recorded reprocessing events for each sensor of the one or more sensors, a number of prior uses for each sensor of the one or more sensors, a level of ambient light present during operation of each sensor of the one or more sensors, or the one or more physiological characteristics of one or more patients obtained during operation of each sensor of the one or more sensors, or any combination thereof. 
     
     
         12 . The system of  claim 1 , wherein the first sensor is configured to transfer first sensor information from the sensor memory to the monitor in response to the first sensor being coupled to the monitor, wherein the first sensor information comprises a serial number of the first sensor, calibration coefficients or information, a number of recorded reprocessing events for the first sensor, a number of prior uses of the first sensor, or a combination thereof. 
     
     
         13 . The system of  claim 1 , wherein the information collection system is configured to store in the database unique sensor identifying information and information related to plural uses of the same sensor in order to determine possible improper or unauthorized remanufacturing of the first sensor.
