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 use with an accessory capable of collecting a parameter of a patient, the medical device capable of at least a basic functionality, an advanced functionality, and of defibrillating the patient, the device comprising:

a housing structured to couple with the accessory;

an energy storage module within the housing for storing an electrical charge that is to be delivered to the patient for the defibrillating; and

a processor in the housing structured to determine whether a data set received from the accessory confirms or not a preset authentication criterion about the accessory,

in which, when the accessory is coupled to the housing, the medical device is capable of the defibrillating and the basic functionality, and

in which the medical device is additionally 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.

2. The medical device of claim 1, in which

the parameter includes one of capnography, pulse oximetry, non-invasive blood pressure, ECG with three or more leads, invasive blood pressure, temperature, heart rate, respiration rate and CPR performance monitoring.

3. The medical device of claim 1, in which the advanced functionality of the medical device is enabled for a limited time after it is determined that the preset authentication criterion is not confirmed.

4. The medical device of claim 1, in which

the basic functionality is to report a first aspect of the monitored parameter, and

the advanced functionality is to report a second aspect of the monitored parameter.

5. The medical device of claim 4, in which

the first aspect is an instantaneous value of the monitored parameter, and

the second aspect is a trend of values of the monitored parameter.

6. The medical device of claim 4, in which

the first aspect is an instantaneous value of an oxygen saturation reading, and

the second aspect is one of carboxyhemoglobin and methemoglobin.

7. The medical device of claim 1, in which

the basic functionality is to report on processing a 3-lead ECG, and

the advanced functionality is to report on processing ECG based on more leads.

8. The medical device of claim 1, in which

the basic functionality is to report one of ventricular fibrillation and ventricular tachycardia, and

the advanced functionality is to report on a detected STEMI.

9. The medical device of claim 1, in which

the advanced functionality is to provide a full set of data for ST plotting, but

the basic functionality is to provide less than the full set for ST plotting.

10. The medical device of claim 1, further comprising:

an accessory detector for detecting whether the accessory is attached to the housing or if the accessory is not attached to the housing.

11. The medical device of claim 1, in which

a query is caused to be transmitted by the processor to the accessory, and

the data set is received responsive to the query.

12. The medical device of claim 1, in which

the data set is received responsive to attaching the accessory to the housing.

13. The medical device of claim 1, in which

the data set is received responsive to power-on of the device.

14. The medical device of claim 1, in which

the received data set is encrypted,

a decryption algorithm is applied by the processor to determine whether the received data set confirms the authentication or does not confirm the authentication.

15. The medical device of claim 1, in which

if no data set is received from the accessory, the authentication is not confirmed.

16. The medical device of claim 1, in which

if the authentication is not confirmed the medical device outputs a warning.

17. The medical device of claim 1, in which

if the authentication is not confirmed the medical device sends a notification to a manufacturer of the medical device.

18. The medical device of claim 1, in which

if the authentication is not confirmed the medical device generates and stores an internal record.

19. The medical device of claim 1, in which

the advanced functionality is an information display functionality.

20. The medical device of claim 1, in which

the advanced functionality is a synchronized cardioversion therapy.

21. The medical device of claim 1, in which

the advanced functionality is a pacing therapy.

22. The medical device of claim 1, in which

the basic functionality is an AED mode, while

the advanced functionality is a manual mode.

23. A method in a medical device for use with an accessory capable of collecting a parameter of a patient and capable of at least a basic functionality, an advanced functionality, and of defibrillating the patient, the method comprising:

after the accessory is coupled to the medical device, determining whether a data set received from the accessory confirms or not a preset authentication criterion about the coupled accessory;

disabling the advanced functionality after it is determined that the preset authentication criterion is not confirmed about the coupled accessory; and

collecting the patient parameter while the advanced functionality is disabled.

24. A control system for a medical device for use with an accessory capable of collecting a parameter of a patient, the medical device capable of at least a basic functionality, an advanced functionality, and of defibrillating the patient, the control system comprising:

a reader structured to read a data set from the accessory;

a processor coupled to the reader and structured to determine whether the data set from the accessory confirms or not a preset authentication criterion about the accessory,

in which, when the accessory is coupled to the housing, the medical device is capable of the defibrillating and the basic functionality, and

in which the control system is structured to enable the advanced functionality of the medical device only when the accessory is coupled to the housing and it is determined that the preset authentication criterion is confirmed.
