System and method for retrofit deployment of a vendor-agnostic medical device integration infrastructure
A retrofit medical device integration infrastructure is disclosed for deployment in already-built healthcare facilities without structural renovation. Modules install at or near existing bedside wall locations, including outlet positions and wall plates, using existing wall boxes or surface enclosures and building services. Device-interface modules couple to heterogeneous medical devices to acquire outputs at the point of care. Wall-mounted distribution components and edge processing units establish a hospital-owned clinical integration plane isolated from a general facility IT network. Outputs are normalized into standardized data objects including device identity, location association, and time information, and routed through authorized communication paths to downstream systems. Coexistence with incumbent vendor monitoring is supported by acquiring parallel copies without disrupting primary workflows. Optional buffering and alternate uplinks provide resilience during connectivity disruption.
