Operating A Portable Medical Device

摘要

Some embodiments of a portable medical device, such as an infusion pump, can receive an external reference signal (e.g., a radio, cellular and/or satellite signal) to provide an automatic time-setting and maintenance operation. In these circumstances, the medical device can maintain accurate time and date information even in the event of a power interruption, a time-zone change and/or an internal clock error, for example. In this manner, the portable medical device provides safe operation and added convenience to the user.

主权项

1. A method of operating an infusion pump system for treatment of diabetes, comprising:
removably attaching a portable controller device to pump device such that the controller device is mechanically mounted with the pump device, the portable controller device having a user interface display device and being in electrical communication with the pump device via an electrical connection; wirelessly receiving at a wireless communication antenna system housed in the portable controller device an external reference signal indicative of a time of day which is transmitted from a portable computing device configured to provide short range wireless communication with the portable controller device; updating an internal time setting of the portable controller device in response to receiving the external reference signal from the portable computing device; and operating the portable controller device to activate a drive system of the pump device based on the updated time setting.
