Supervisory Hemorrhagic Shock Control for Coordinated Resuscitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated patient care devices often operate independently and lack the ability to prioritize care based on overall patient status, leading to potential conflicts and contradictory interventions, especially in emergency and combat trauma environments.
Innovation Solution
A Supervisory Algorithm for Casualty Management (SACM) device that coordinates and prioritizes the operation of automated systems like tourniquet and resuscitation controllers, using algorithms to synchronize care and prevent conflicts by monitoring physiological inputs and adjusting device parameters to maintain optimal patient conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If multiple automated patient care devices operate independently, then each device can execute its function autonomously and simply, but the devices may provide contradictory care and harm the patient due to lack of awareness of overall patient status
Solution Approach 1:
The patent merges multiple independent automated patient care devices into a unified system with a central controller that coordinates their operations. The controller integrates inputs from multiple sensors and devices, processes them centrally, and coordinates their actions to provide consistent care, eliminating the harmful effects of independent contradictory operations while preserving automation benefits
Solution Approach 2:
The central controller acts as an intermediary between multiple automated devices and the patient. It receives data from various devices, processes it according to patient status, and sends coordinated commands to each device, ensuring that their operations are harmonized and do not conflict, thus maintaining reliability while allowing autonomous execution
2Ease of operation
If automated devices use simple input data and decision-making, then the devices remain easy to use and reliable, but they lack the insight to prioritize care appropriately in complex situations
Solution Approach 1:
The patent adds a new dimension of complexity at the control system level rather than at the individual device level. The central controller implements sophisticated algorithms that consider multiple parameters and prioritize care appropriately, while individual devices remain simple in operation. This dimensional separation allows complex adaptability without compromising ease of use
3Reliability
If a clinician manually prioritizes one line of treatment over another, then care can be optimized for overall patient status, but the clinician's time and attention are consumed by coordination tasks
Solution Approach 1:
The system enables self-service by allowing automated devices to coordinate their own operations through the central controller. The controller automatically prioritizes treatments based on patient status without requiring continuous clinician intervention. This transfers the coordination task from the clinician to the system, preserving care optimization while freeing clinician time for other critical tasks
