Hospital Bed Siderail Width Adjustment and Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hospital beds for bariatric patients lack effective siderail systems that can securely support patients up to 1000 pounds and accommodate varying patient sizes, with limited adjustability for caregiver access and patient egress.
Innovation Solution
A hospital bed with a frame, deck, and mattress featuring siderails that can move between blocking, intermediate, and egress positions, equipped with a width adjustment assembly and latching mechanisms to secure these positions, ensuring patient safety and caregiver access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional siderail systems are used, then the structure is simple, but they cannot securely support patients up to 1000 pounds
Solution Approach 1:
The patent applies dynamics by making the siderail system adjustable between multiple positions (blocking, intermediate, egress) rather than fixed. The siderails can be dynamically repositioned to accommodate different patient needs and caregiver access requirements while maintaining structural integrity for heavy patients up to 1000 pounds.
Solution Approach 2:
The siderail system is segmented into multiple independent components including upper and lower siderails, blocking members, and latching mechanisms. This segmentation allows each component to be optimized for strength while the overall system maintains adjustability, resolving the contradiction between strength and complexity.
2Adaptability or versatility
If fixed width deck is used, then manufacturing is simpler, but it cannot accommodate varying patient sizes
Solution Approach 1:
The deck is designed with dynamic width adjustability through the width adjustment assembly that allows the deck to expand or contract. This enables the same deck structure to accommodate varying patient sizes while maintaining relatively simple manufacturing processes through modular design.
3Reliability
If blocking siderails are used, then patient safety is improved, but caregiver access and patient egress are limited
Solution Approach 1:
The siderail system incorporates dynamic positioning capability with three distinct positions: blocking position for maximum patient safety, intermediate position for balanced safety and access, and egress position for easy patient exit. The latching mechanism enables smooth transitions between these positions, resolving the contradiction between safety and accessibility.
4Strength
If heavy duty frame is used for bariatric patients, then patient weight support is improved, but overall bed weight increases
Solution Approach 1:
The patent utilizes composite construction in the frame and siderail assemblies, combining materials with different properties to achieve high strength-to-weight ratio. This allows the bed to support heavy patients up to 1000 pounds while minimizing the overall weight of the bed structure itself.
