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 blood processing device having improved network access security, comprising:
- a network interface circuit configured to provide communications over a network, the network interface circuit configured to provide a communication port;
- and
- a processing circuit configured to:
- open a communication port on the network interface circuit to establish a communication session;
- transmit blood processing device data to a server computer over the network during the communication session;
- after the blood processing device data is transmitted to the server, transmit to the server computer a request for a command from the server computer during the communication session;
- receive a command from the server computer;
- determine whether the command is on a predetermined list of commands, the predetermined list of commands being a subset of functions the blood processing device is configured to perform;
- process the command;
- and
- close the communication port on the network interface circuit.
A medical device having improved network access security, comprising:
- a network interface circuit configured to provide communications over a network, the network interface circuit configured to provide a communication port;
- and
- a processing circuit configured to:
- open a communication port on the network interface circuit to establish a communication session;
- transmit medical device data to a server computer over the network during the communication session;
- after the medical device data is transmitted to the server, transmit to the server computer a request for a command from the server computer during the communication session;
- receive a command from the server computer;
- determine whether the command is on a predetermined list of commands, the predetermined list of commands being a subset of functions the medical device is configured to perform;
- process the command;
- and
- close the communication port on the network interface circuit.
A medical device having improved network access security, comprising:
- a processing circuit configured to:
- open a communication port to establish a communication session;
- transmit medical device data to a server computer via the communication port during the communication session;
- after the medical device data is transmitted to the server, transmit to the server computer a request for a command from the server computer during the communication session;
- receive a command from the server computer in response to the request for a command;
- process the command;
- after processing the command, transmit another request for command to the server, wherein the processing circuit is configured to continue transmitting requests for command after processing commands until an indication of no further commands is received from the server;
- and
- close the communication port after receiving the indication of no further commands from the server.
