Abstract

The present disclosure is generally directed to maintaining sensor quality standards and/or preventing improper remanufacture of sensors, such as pulse oximetry sensors. Present embodiments may include a system for facilitating the monitoring of physiologic conditions that includes a biometric measurement device configured to translate a unique biological feature of a patient into electronic data, a memory device configured to receive and store the electronic data after an initial reading of the unique biological feature by the biometric measurement device, and a processor configured limit access to the memory based on whether the biometric measurement device provides subsequent electronic data matching the electronic data from the initial reading.

Claims

1. A system for facilitating the monitoring of physiologic conditions, comprising:

a biometric measurement device capable of translating a unique biological feature of a patient into electronic biometric data;

a pulse oximetry sensor capable of obtaining physiologic data from the patient comprising;

a light emitter for directing light at the patient;

a light detector mounted to receive light from the patient that is indicative of the physiologic data; and

a memory device capable of receiving and storing the biometric data after an initial reading of the unique biological feature by the biometric measurement device; and

a processor configured to limit access to the memory and/or prevent sensor function based on whether the biometric measurement device provides subsequent biometric data corresponding to the biometric data from the initial reading.

2. The system of claim 1, wherein the processor is capable of associating the biometric data with the physiologic data obtained from the patient.

3. The system of claim 2, wherein the processor is capable of encoding the physiologic data based on the biometric data such that access is limited to the physiologic data without the subsequent biometric data corresponding to the biometric data to decode the physiologic data.

4. The system of claim 1, wherein the pulse oximetry sensor comprises the processor and/or the biometric measurement device.

5. The system of claim 1, wherein the processor is capable of prompting acquisition of the subsequent biometric data via the biometric measurement device under predefined conditions.

6. The system of claim 5, wherein the predefined conditions comprise a condition wherein the sensor is activated.

7. The system of claim 1, wherein the memory device comprises a dedicated storage location for the biometric data.

8. The system of claim 1, wherein the biometric device is a component of a pulse oximeter.

9. The system of claim 1, wherein the processor is a component of a pulse oximeter.

10. The system of claim 1, wherein the biometric measurement device is configured to electronically communicate with the processor.

11. The system of claim 1, wherein the biometric measurement device comprises an optical reader configured to scan a fingerprint, an iris, a retina, a face, and/or a palm into the electronic data.

12. The system of claim 1, wherein the biometric measurement device comprises a DNA testing device.

13. A method of remanufacturing a sensor to provide a remanufactured sensor or sensor package, comprising:

sterilizing a used sensor body including a used sensor memory or installing the used sensor memory into a new sensor body;

erasing a memory field of the used sensor memory storing electronic data converted from a biological feature by a biometric measurement device; and

storing replacement data in the memory field of the used sensor memory.

14. The method of claim 13, comprising wiping all or a portion of the used sensor memory.

15. The method of claim 13, comprising storing an encryption signature on the used sensor memory.

16. A sensor, comprising:

a light emitter capable of emitting light into tissue;

a light detector capable of detecting light and producing a signal indicative of physiologic data based on the detected light;

a biometric measurement device configured to translate a unique biological feature of a patient into electronic biometric data;

a memory device capable of receiving and storing the biometric data after an initial reading of the unique biological feature by the biometric measurement device; and

a processor capable of guarding access to the memory device and/or limiting operability of functional features of the sensor based on whether the biometric measurement device provides subsequent biometric data corresponding to the biometric data from the initial reading.

17. The sensor of claim 16, wherein the biometric measurement device comprises an optical reader configured to scan a fingerprint, an iris, a retina, a face, and/or a palm into the electronic data.

18. The sensor of claim 16, wherein the biometric measurement device comprises a DNA testing device.

19. The sensor of claim 16, wherein the processor is capable of associating the biometric data with the physiologic data.

20. The sensor of claim 19, wherein the processor is capable of encrypting the physiologic data based on the biometric data.
