System and method for medical device authentication
First Claim
1. A method of securely transmitting medical data generated by a medical device, the method comprising:
- creating a first account on a central medical information computer for the medical device;
generating a first digital certificate for the medical device;
mapping the first digital certificate to the first account;
transferring the first digital certificate to the medical device;
creating a second account on the central medical information computer for a user interface device;
generating a second digital certificate for the user interface device;
mapping the second digital certificate to the second account;
transferring the second digital certificate to the user interface device;
receiving medical data at the central medical information computer using the first digital certificate, the medical data being generated by the medical device; and
transmitting the medical data from the central medical information computer to the user interface device using the second digital certificate.

Abstract
A method and system for medical device authentication is disclosed. The system may include a plurality of digital assistants and a plurality of medical devices (e.g., infusion pumps) communicating over a wired or wireless network. Because some of the data being transmitted is confidential medical data, the data is preferably encrypted and only communicated in the clear to authorized users and devices. In order to setup a new digital assistant or medical device, a commissioning phase of the authentication process may be performed. Each time a commissioned device is powered up, an authentication process is preferably performed in order to verify communication is occurring with an authorized device and/or user. Once a device and/or user is authenticated, secure one-way and/or two-way communication may occur in order to pass parameters, instructions, data, alarms, status information, and any other type of information between digital assistants, medical devices, and/or servers.
