Method for protecting a medical device
First Claim
1. A method for protecting a medical device against unauthorized removal from a predefined location area, comprising:
- transmitting protection signals by the medical device;
evaluating received protection signals received by the medical device from a plurality of selected devices; and
activating a specific operating state of the medical device based on the evaluation,wherein the evaluation of the received protection signals includes determining a combination value based on the received protection signals received from the plurality of selected devices using a combination rule.

Abstract
A method is disclosed for protecting a medical device against unauthorized removal from a predefined location area. To this end the device to be protected and/or at least one further device in the predefined location area transmits protection signals. The protection signals transmitted by the device to be protected and/or the protection signals received by the device to be protected are then evaluated and a specific operating state of the device to be protected is activated as a function of a result of the evaluation. A corresponding system for protecting a medical device and a medical device for use with such a protection method or system is also described.
