Abstract: A system and method for performing database synchronization between a first database of a first device and a second database of a second device is disclosed. The first database stores medical records having non-time based counter values associated thereto. The second database stores medical records having timestamps associated thereto. The first device includes a first database synchronization module that maintains a last timestamp indicating a last medical record that was received from the second device. The first database synchronization module transmits, to the second device, a request for synchronization and the last timestamp. The second device includes a second database synchronization module that maintains a last counter value indicative of a last medical record that was received from the first device, and that transmits, to the first device, a second request for synchronization and the last counter value.

Abstract: A method performed by a medical device includes: receiving electronic medical data from one or more input devices; storing the medical data in a first datastore associated with the medical device; receiving a non-expiring, cryptographic token from a server in response to a transmission of account data, the non-expiring, cryptographic token associated with the medical device for synchronizing the medical data stored in the first datastore with the medical data stored in the second datastore that is associated with the server; transmitting the non-expiring, cryptographic token to the server for authentication by the server; selectively transmitting at least a portion of the medical data stored in the first datastore to the server for storage in the second datastore; selectively receiving at least a portion of the medical data stored in the second datastore from the server; and selectively storing the medical data received from the server in the first datastore.
