Abstract

Medical devices historically have been monolithic units --- developed,
validated, and approved by regulatory authorities as standalone entities.
Despite the fact that modern medical devices increasingly incorporate
connectivity mechanisms that enable device data to be streamed to
electronic health records and displays that aggregate data from multiple
devices, connectivity is not being leveraged to allow an integrated
collection of devices to work together as a single system to automate
clinical work flows. This is due, in part, to current regulatory
policies which prohibit such interactions due to safety concerns.
In previous work, we proposed an open source middleware framework
and an accompanying model-based development environment that could
be used to quickly implement medical device coordination applications
--- enabling a "systems of systems" paradigm for medical devices.
Such a paradigm shows great promise for supporting many applications
that increase both the safety and effectiveness of medical care as
well as the efficiency of clinical workflows. In this paper, we report
on our experience using our Medical Device Coordination Framework
({MDCF)} to carry out a rapid prototyping of one such application
--- a multi-device medical system that uses closed loop physiologic
control to affect better patient outcomes for Patient Controlled
Anelgesic ({PCA)} pumps.
