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.

First claim

What is claimed is:

1. A 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 one of a basic functionality, an advanced functionality, and of defibrillating the patient, the system comprising:
a data storage device in the accessory configured to store a data set;
a reader structured to read a data set from the data storage device;
a processor coupled to the reader and structured to determine whether the data set from the data storage device confirms a preset authentication criterion about the accessory,
in which the defibrillating and the basic functionality of the medical device are enabled and the advanced functionality of the medical device is disabled when the accessory is coupled to the medical device and it is determined that the preset authentication criterion is not confirmed, and
in which the medical device is capable of the defibrillation, the basic functionality and the advanced functionality when the accessory is coupled to the medical device and it is determined that the preset authentication criterion is confirmed.

2. The system of claim 1 , in which the data storage device comprises a programmable read-only memory, an erasable programmable read-only memory, a flash memory, a radio frequency identification tag, or a bar code.

3. The system of claim 1 , in which the accessory comprises an electrode.

4. The system of claim 3 , in which the electrode comprises an ECG electrode.

5. The system of claim 1 , in which the accessory is selected from a group consisting of a non-invasive blood pressure hose, a pressure cuff, one or more leads, a temperature measuring device, a capnography device, a respiratory device, a communication device, and a physiological parameter sensor.

6. The system of claim 1 , in which the reader comprises an radio frequency identification reader, a bar code reader, or an infrared reader.

7. The system 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.

8. The system 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.

9. The system 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.

10. The system of claim 1 , in which the data set is received responsive to attaching the accessory to the housing.

11. The system of claim 1 , in which the data set is received responsive to power-on of the device.

12. The system 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.

13. The system of claim 1 , in which if no data set is received from the accessory, the authentication is not confirmed.

14. The system of claim 1 , in which if the authentication is not confirmed the medical device outputs a warning.

15. A method for enabling advanced functionality in a medical device, the method comprising:
collecting patient parameter data by an accessory operatively coupled to a patient and to a medical device, the medical device comprising a defibrillator and further comprising basic functionality and advanced functionality, both basic and advanced functionality related to patient parameter data collected by the accessory;
receiving by the accessory a query from the medical device;
responsive to the query, transmitting an authentication data set from the accessory to the medical device; and
wherein the authentication data set is configured to cause advanced functionality of the medical device to be enabled or disabled responsive to whether the authentication data set confirms a preset authentication criterion, wherein the advanced functionality is in addition to the medical device's basic functionality.

16. The method of claim 15 , wherein when the advanced functionality is enabled in the medical device before the accessory responds to the query, responsive to the authentication data set not confirming the preset authentication criterion, the authentication data set causes the advanced functionality to be disabled after a predetermined time.

17. The method of claim 15 , wherein attaching the accessory to the medical device causes the medical device to transmit the query.

18. The method of claim 15 , in which the accessory transmits the authentication data set in encrypted form.

19. The method of claim 15 , wherein when the advanced functionality is enabled in the medical device before the accessory responds to the query, the authentication data set causes the advanced functionality to not be disabled responsive to the preset authentication criterion being confirmed.

20. The method of claim 15 , wherein when the advanced functionality is disabled in the medical device before the accessory responds to the query, the authentication data set causes the advanced functionality to be enabled when the preset authentication criterion is confirmed.

21. The method of claim 15 , wherein the accessory comprises an electrode.

22. The method of claim 21 , wherein the electrode comprises an ECG electrode.
