Abstract

In an embodiment, a medical device can be used with a power adapter system. In addition, it can receive a data set from the power adapter system, and examine the data set to determine whether the data set confirms or not an authentication of the power adapter for use with the medical device. If the authentication is not confirmed, the external medical device can operate differently than otherwise. For example, power can be drawn from the power adapter system only if an inside battery is not charged.

Claims

1. A medical device that is to receive power via a power adapter system, the medical device capable of operating to defibrillate a patient according to a first protocol if a preset authentication about the power adapter system is confirmed, and capable of operating to defibrillate the patient according to a second protocol different from the first protocol if the authentication is not confirmed, the medical device comprising:

a housing;

a capacitor for storing an electrical charge that is to be delivered to the patient as part of defibrillating according to either the first protocol or the second protocol;

an inside battery in the housing distinct from the power adapter system and capable of storing an electrical charge that is to be delivered to the capacitor;

means for receiving a data set from the power adapter system when the power adapter system is coupled with the housing; and

a processor capable of recognizing whether the received data set confirms the authentication or not, in which

according to the first protocol, power is drawn from the power adapter system even if the inside battery is charged, but

according to the second protocol, power is drawn from the power adapter system only if the inside battery is not charged.

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

a display for displaying at least a portion of the data set.

3. The medical device of claim 1, in which

if no data set is received from the power adapter system, the authentication is not confirmed.

4. The medical device of claim 1, in which

a query is transmitted to the power adapter system, and the data set is received responsive to the query.

5. The medical device of claim 1, in which

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

6. The medical device of claim 1, in which

the data set is received responsive to electrical engagement of the power adapter system with the housing.

7. The medical device of claim 1, in which

the received data set is encrypted.

8. The medical device of claim 1, in which

according to the first protocol, a first type of indication about a status of the power adapter system is displayed at a screen of the device, but

according to the second protocol, a second type of indication different from the first type is displayed at the screen.

9. The medical device of claim 1, in which

the medical device exhibits a warning about the authentication not being confirmed when operating according to the second protocol, but not when operating according to the first protocol.

10. The medical device of claim 1, in which

according to the first protocol, the device has the capability of operating in both a manual mode and an AED mode, but

according to the second protocol, the device has the capability of operating in the AED mode but not in the manual mode.

11. The medical device of claim 1, in which

while a functionality of defibrillating is operable according to both the first protocol and to the second protocol,

a certain functionality other than the functionality of defibrillating is operable according to the first protocol, but not according to the second protocol.

12. The medical device of claim 11, in which

the certain functionality is an information display functionality.

13. The medical device of claim 11, in which

the certain functionality is a synchronized cardioversion therapy.

14. The medical device of claim 11, in which

the certain functionality is a pacing therapy.

15. The medical device of claim 11, in which

the certain functionality is to monitor a parameter of the patient.

16. The medical device of claim 15, in which

the parameter includes one of capnography, pulse oximetry, non-invasive blood pressure, end tidal CO2, ECG, invasive blood pressure, temperature, and CPR performance monitoring.
