Ventilator Interface Hierarchy for Safe Concurrent Data Exchange

The patent segments the data input functionality by interface, assigning priority levels to different interfaces (e.g., user interface, service interface, remote interface). When a data input is received via one interface, the system selectively blocks data inputs from lower-priority interfaces while allowing them from higher-priority interfaces. This segmentation resolves the contradiction by maintaining multi-interface adaptability while ensuring safety through hierarchical control.

The patent implements dynamic blocking of interfaces based on real-time conditions. The blocking state of each interface is not fixed but changes dynamically according to the active interface and system state. When a high-priority interface becomes active, lower-priority interfaces are dynamically blocked; when the high-priority interface becomes inactive, the blocking is released. This dynamic approach maintains safety while preserving flexibility for legitimate multi-interface operations.

The patent applies partial action by allowing data output operations to proceed concurrently with ongoing ventilation therapy, rather than completely suspending data outputs. The system performs data outputs in parallel with therapy delivery, utilizing available processor capacity and memory resources. This partial execution approach maintains productivity for both therapy delivery and data management without requiring complete resource allocation to either function.
