Magnetic CPR Dump Valve for Rapid Mattress Deflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable mattress systems with multiple zones often malfunction during CPR dump protocols due to complex mechanical operations, leading to slow deflation and potential delays in emergency care, especially in confined spaces where a quick release plate may not be feasible.
Innovation Solution
A patient support system with a fluid bladder, air pump, manifold, and CPR dump system featuring a magnetized alignment apparatus and stop mechanism, allowing for rapid deflation by dislodging a plug from the manifold aperture using a rod and handle, ensuring the bladder deflates within a predetermined time frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional CPR dump system with multiple mechanical operations (blower reversal, valve switching, manifold directing) is used, then the system can deflate bladders, but the system is prone to malfunctions and delays due to the complexity of mechanical operations
Solution Approach 1:
The invention extracts the plug from the complex mechanical CPR dump system and makes it the primary deflation mechanism. By removing the plug manually, air is rapidly expelled through the valve without requiring blower reversal, manifold directing, or coordinated valve switching. This simplifies the system by making the plug the dominant feature rather than one component among many mechanical operations.
Solution Approach 2:
The invention segments the CPR dump function into independent components: the plug, the valve, and the blower. The plug can be removed independently to initiate rapid deflation, while the blower can independently reinflate the bladder. This segmentation allows each component to perform its function without requiring complex coordination between multiple mechanical operations, thereby improving reliability.
2Speed
If a quick release plate system is used for rapid deflation, then the deflation speed is improved, but the system cannot be used in confined spaces where a quick release plate is not feasible
Solution Approach 1:
The invention nests the plug and rod assembly within the existing mattress structure, specifically integrating it into the air control unit housing. The rod can be accessed through an opening in the housing, allowing manual plug removal without requiring external space for a quick release plate mechanism. This nesting approach enables rapid deflation functionality within the confined boundaries of the existing mattress structure.
Solution Approach 2:
The rod acts as an intermediary tool that allows manual plug removal without requiring a separate quick release plate mechanism. The rod transmits the user's pulling force to the plug, enabling rapid deflation initiation from outside the confined housing space. This intermediary approach provides quick release functionality adapted to confined space constraints.
3Ease of operation
If multiple mechanical operations are used in the CPR dump system, then the system can control air flow, but the likelihood of malfunction increases with each additional mechanical component
Solution Approach 1:
The invention enables the system to serve itself by allowing manual plug removal to initiate rapid deflation without requiring the blower, valves, or manifold to perform coordinated mechanical operations. The plug removal itself creates the pressure differential needed for air expulsion, eliminating the need for complex mechanical control during the deflation process. This self-service approach reduces malfunction risk while maintaining air flow control capability.

Implementation Method 1
a magnetized stop mechanism fastened to the rod between the magnetized alignment apparatus and the container's opening and magnetically attached to the magnetized alignment apparatus which insures the plug is lodged in the manifold's aperture

AI summary
The present invention involves a patient support system. The support system has a fluid bladder and a container. The container has an air pump, a manifold and a CPR dump system. The CPR dump system has a manifold aperture, a plug positioned in the manifold's aperture, a rod interconnected to the plug and protruding from the container's opening, a magnetized alignment apparatus, and a magnetized stop mechanism. The magnetized stop mechanism fastens to the rod and magnetically attaches to the magnetized alignment apparatus which insures the plug is lodged in the manifold's aperture. When a user wants to expeditiously deflate the inflatable fluid bladder, the user pulls on the distal end with sufficient force to detach the magnetized stop mechanism from the magnetized alignment apparatus thereby the plug dislodges from the manifold aperture and allows the inflatable fluid bladder to deflate within a predetermined time frame.
