Medical device with encrypted identification

摘要

A medical device with a medical apparatus (2) includes an accessory port, and with at least one accessory piece (1) having a connection element that is complementary to the accessory port. The connection element includes a storage unit where coded identification information is stored. With accessory piece (1) connected to device (2) coded or un-coded identification information is readable by a readout unit disposed in the section of the accessory port. In the case of reading coded identification information, de-codable, read-out and de-coded identification information is compared to identification information stored in readout unit. The medical device is activated when the identification information matches the desired identification information. The device is blocked when the identification information does not match. The coded identification information is de-coded by means of a proprietary key code.
