Patent Images
1. A communication system for connecting a pump motor controller with a user interface controller, the communication system comprising:
- a pump motor controller configured to transmit a first message to a user interface controller, the first message comprising a request for an address;
a user interface controller configured to;
receive the first message;
determine in a stored table that there is an entry corresponding to the pump motor controller;
generate a connection identifier for the pump controller based on the lookup in the stored table;
transmit the connection identifier to the pump controller;
receive instructions for infusion, the instructions comprising infusion parameters;
transmit the instructions in a second message including the connection identifier to the pump motor controller;
receive a request from a second pump motor controller for an address, the second pump motor controller configured to replace the pump motor controller;
determine in the stored table the entry corresponding to the pump motor controller that is being replaced; and
respond to the second pump motor controller'"'"'s request with the same determined entry.

Abstract
A medical device communication method that may be implemented within a variety of medical devices including but not limited to infusion pumps. The method may be implemented with a protocol stack for at least intra-device communication. Embodiments provide connection-oriented, connectionless-oriented, broadcast and multicast data exchange with priority handling of data, fragmentation, and reassembly of data, unique static and dynamic address assignment and hot swap capability for connected peripherals or subsystems.

1. A communication system for connecting a pump motor controller with a user interface controller, the communication system comprising:
-
a pump motor controller configured to transmit a first message to a user interface controller, the first message comprising a request for an address; a user interface controller configured to; receive the first message; determine in a stored table that there is an entry corresponding to the pump motor controller; generate a connection identifier for the pump controller based on the lookup in the stored table; transmit the connection identifier to the pump controller; receive instructions for infusion, the instructions comprising infusion parameters; transmit the instructions in a second message including the connection identifier to the pump motor controller; receive a request from a second pump motor controller for an address, the second pump motor controller configured to replace the pump motor controller; determine in the stored table the entry corresponding to the pump motor controller that is being replaced; and respond to the second pump motor controller'"'"'s request with the same determined entry. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)
