Abstract

Embodiments are directed to a medical device, such as a defibrillator, for use with an accessory capable of collecting a parameter of a patient. The medical device is capable of at least performing a basic functionality, an advanced functionality, and of defibrillating the patient. The medical device includes an energy storage module within a housing for storing an electrical charge that is to be delivered to the patient for the defibrillating. The medical device includes a processor structured to determine whether a data set received from the accessory confirms or not a preset authentication criterion about the accessory. Although when the accessory is coupled to the housing the medical device is capable of the defibrillating and the basic functionality, the medical device is capable of the advanced functionality only when the accessory is coupled to the housing and it is determined that the preset authentication criterion is confirmed. Embodiments also include methods of operation and a programmed solution.

Claims

1. A medical device for an accessory capable of collecting a parameter of a patient, comprising:

a housing configured to couple with a remote accessory configured to collect a parameter of a patient;

an energy storage module disposed within the housing configured to store an electrical charge and configured to deliver the electrical charge to the patient for defibrillating the patient, the medical device further configured to have basic functionality and advanced functionality;

a processor disposed in the housing and configured to determine whether a data set received from the remote accessory confirms preset authentication criterion about the remote accessory, wherein the data set corresponds to information stored in a memory of the remote accessory; and

a memory coupled to and accessible by the processor, the memory configured to store authentication and readiness information and to authenticate the accessory.

2. The medical device of claim 1, in which the advanced functionality of the medial device is enabled in response to confirming the authentication information against the preset authorization criterion.

3. The medical device of claim 2, in which the advanced functionality of the medical device is enabled for a limited time.

4. The medical device of claim 1, wherein advanced functionality of the medical device is disabled in response to failing to confirm the authentication information against the preset authorization criterion.

5. The medical device of claim 4, wherein a warning is displayed on a display in response to the failing to confirm the authentication information.

6. The medical device of claim 1, wherein the received data set is encrypted when received at the medical device.

7. The medical device of claim 1, wherein the remote accessory comprises an electrode.

8. The medical device of claim 7, wherein the electrode comprises an electrocardiogram electrode.

9. The medical device of claim 7, wherein the electrode comprises an defibrillation electrode.

10. A method in a medical device for use an accessory capable of collecting a parameter of a patient, comprising:

receiving a data set from a remote accessory;

determining whether the data set confirms a preset authentication criterion about the remote accessory;

disabling at least one function of the medical device in response to not confirming the data set received against the preset authentication criterion; and

collecting at least one patient parameter while the at least one function is disabled.

11. The method of claim 10, wherein the receiving a data set from a remote accessory comprises communicatively coupling the remote accessory to the medical device through a wireless communication channel.

12. The method of claim 10, further comprising, by the medical device, coupling of the remote accessory to a processor of the medical device, wherein the remote accessory comprises a defibrillation electrode and a memory, wherein the data set corresponds to information stored in the memory.

13. The method of claim 10, wherein the at least one function is enabled prior to confirming the authentication data.

14. The method of claim 10, further comprising collecting at least one patient parameter after the at least one function is enabled.

15. A control system for a medical device for use with an accessory capable of collecting a parameter of a patient, comprising:

a reader coupled to a medical device and configured to read a data set from a remote accessory coupled to the medical device, wherein the medical device is configured to defibrillate a patient;

a processor coupled to the reader and configured to determine whether the data set from the remote accessory confirms a preset authentication criterion about the accessory,

wherein the processor is further configured to enable at least one function of the medical device in response to determining that the preset authentication criterion is confirmed and the remote accessory is authenticated.

16. The control system of claim 15, wherein the at least one function of the medical device is enabled for a limited time.

17. The control system of claim 15, wherein the at least one function of the medical device is disabled in response to failing to confirm the authentication information against the preset authorization criterion.

18. The control system of claim 15, further comprising a decryption module configured to decrypt the received data set, wherein the received data set is encrypted when received at the medical device.

19. The control system of claim 15, wherein the remote accessory comprises an electrode.

20. The control system of claim 15, wherein the reader comprises a radio-frequency identification reader configured to couple the remote accessory to the medical device through a wireless communication coupling.
