Abstract
A method of improving network access security on a medical device includes opening a communication port on the medical device to establish a communication session on a network and transmitting medical device data to a computer over the network during the communication session. After the medical device data is transmitted to the computer, the method includes transmitting to the computer a request for a command from the computer during the communication session. The method also includes receiving a command from the computer, processing the command, and closing the communication port on the medical device.
Claims20
A method of improving network access security on an infusion pump, comprising:
- opening a communication port on a network interface circuit of an infusion pump to establish a communication session on a network;
- transmitting infusion pump data to a server computer over the network during the communication session;
- after the infusion pump data is transmitted to the server, transmitting to the server computer a request for a command from the server computer during the communication session;
- receiving a command from the server computer;
- determining whether the command is on a predetermined list of commands, the predetermined list of commands being a subset of functions the infusion pump is configured to perform;
- processing the command;
- and
- closing the communication port on the network interface circuit.
A method of improving network access security on a server computer, comprising:
- determining a need to command an infusion pump;
- storing an indication of the need to command the infusion pump in a memory;
- after storing the indication of the need to command the infusion pump in memory, establishing a communication session with the infusion pump to receive an infusion pump data message from an infusion pump;
- storing infusion pump data from the message in the memory;
- after storing the infusion pump data, receiving a request for a command from the infusion pump during the communication session;
- generating an infusion pump command based on the indication of the need to command the infusion pump;
- transmitting the infusion pump command to the infusion pump;
- receiving additional infusion pump data in response to the infusion pump command;
- and
- storing the additional infusion pump data in memory.
