Supervisory Casualty Management Controller for Automated Trauma Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated patient care systems in emergency and combat trauma environments often operate independently and in a closed-loop manner, leading to potential conflicts and contradictory care when multiple devices are used simultaneously, lacking the ability to prioritize care based on overall patient status.
Innovation Solution
The implementation of a Supervisory Algorithm for Casualty Management (SACM) device that manages decisions and interplay between various automated systems, such as automated tourniquets and adaptive resuscitation controllers, to prioritize patient care by synchronizing fluid infusion and hemorrhage control based on overall patient status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If multiple automated patient care devices operate independently in closed-loop manner, then each device can provide specialized care functions, but the devices may provide contradictory care and conflict with each other
Solution Approach 1:
The patent merges multiple independent automated devices into a unified hierarchical system where a supervisory controller coordinates the operations of subordinate devices. This integration ensures that devices work together synergistically rather than independently, eliminating conflicting actions while preserving the automation benefits of each individual device.
Solution Approach 2:
The supervisory controller acts as an intermediary between multiple automated devices and the patient care system. It receives data from various sensors, processes information according to prioritization algorithms, and coordinates device operations to ensure consistent, non-contradictory care while maintaining automation.
2Device complexity
If automated devices operate without awareness of overall patient status, then device complexity is reduced, but devices cannot prioritize care based on comprehensive patient condition
Solution Approach 1:
The system segments functionality into two levels: simple automated devices that execute specific tasks without complex decision-making, and a supervisory controller that processes comprehensive patient data and prioritizes care. This segmentation maintains device simplicity while achieving adaptive prioritization through the supervisory layer.
Solution Approach 2:
The supervisory controller provides universal coordination across all automated devices, enabling them to adapt to different patient scenarios. Rather than making each device complex, the universal supervisor handles prioritization and context-awareness, allowing simple devices to function effectively in diverse situations.
3Adaptability or versatility
If multiple automated devices are deployed simultaneously, then more care functions are available, but managing and coordinating these devices becomes difficult
Solution Approach 1:
The patent combines the management of multiple devices into a single supervisory controller that handles coordination centrally. This merging approach maintains the availability of multiple care functions while simplifying management, as the supervisor unifiedly coordinates all devices rather than requiring complex inter-device communication and management protocols.

AI summary
Methods, devices, systems, and computer-readable media are described for providing adaptive and closed loop hemorrhagic shock resuscitation. A computing device may cause activation of an automated tourniquet configured to impede extremity bleeding. The computing device may additionally cause activation of an adaptive resuscitation controller by determining a desired mean arterial pressure setpoint and causing, based on the desired mean arterial pressure setpoint, the adaptive resuscitation controller to infuse fluids into the patient. The computing device may then monitor component pressure measurements of the automated tourniquet and blood pressure parameters of the patient. The computing device may then, based on the component pressure measurements, cause modification of one or more operating parameters of the automated tourniquet. The computing device may additionally and/or alternatively, based on comparing the blood pressure parameters to the desired mean arterial pressure setpoint, cause the adaptive resuscitation controller to infuse fluids into the patient.
