Medical device with dual communications bus
First Claim
1. A medical device comprising:
- at least two units for monitoring and/or controlling the medical device, said units including at least one computer with a microprocessor, and at least one unit having a second computer with a second microprocessor;
first and second communications buses, with each of the computers being attached to either the first or the second communications bus; and
a connecting line extending between the first and second communications buses which can be interrupted by a switch and by which the two communications buses can be connected to form a uniform communications bus.

Abstract
A medical appliance having an auxiliary computer system in addition to its action computer system, and further having two communications buses. The auxiliary computer system independently monitors the functional mode of the action computer system and can induce a reliable state of the appliance in an emergency. To easily, quickly and reliably implement a programming, the execution of test sequences, the diagnosis and the maintenance of such an appliance, a connection line, which can be interrupted by a switch, is arrange between the communication buses, and both communications buses can be connected to form a unified communications bus via the communication line. A method for executing such a programming process, testing process, diagnostic process and/or maintenance process of a medical appliance is also provided.

18. A method for implementing a programming, test, diagnosis and/or maintenance operation of a medical device, the device having at least two units for monitoring and/or controlling thereof which include at least one computer with a microprocessor each, and where at least one unit contains a second computer with a second microprocessor, the device further having two communications buses, where each of the computers is attached to either the first or the second communications bus, and an interface to an external device, which is attached to one of the computers or one of the communications buses, said method comprising the steps of:
-
attaching an external device to the interface;
connecting the two communications buses to form a uniform communications bus;
carrying out the programming, test, diagnostic and/or maintenance operation using the external device; and
separating the communications buses upon completion of the programming, test, diagnostic and/or maintenance operation. - View Dependent Claims (19)
