Hospital Bed Siderail Gap Fillers for Entrapment Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hospital beds with siderails often have gaps between the siderails and the headboard or footboard, which can compromise patient safety by allowing falls or entrapment, and existing solutions do not adequately address these gaps for enhanced safety coverage.
Innovation Solution
The design incorporates vertical and horizontal siderail extensions, pivotally mounted gap fillers that can be activated by gravity or cams to fill gaps between siderails and the mattress or between siderails and the bed frame, and a mechanism for the siderails to be rotated from a deployed to a stowed position underneath the bed frame, ensuring continuous coverage and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional siderails are used, then the bed structure is simple, but gaps exist between siderails and headboard/footboard compromising patient safety
Solution Approach 1:
The siderail system is divided into multiple segments: the main siderail, vertical extensions, and horizontal extensions. These segments can be independently adjusted and positioned to fill gaps between the siderail and headboard/footboard, thereby improving patient safety without requiring a completely complex integrated structure.
Solution Approach 2:
The siderail incorporates movable and adjustable components including telescopic vertical extensions and horizontal extensions that can be dynamically positioned. The siderail can be raised, lowered, and extended to adapt to different bed configurations and patient needs, maintaining safety while allowing structural flexibility.
2Area of stationary object
If siderail extensions and gap fillers are added, then gap coverage is improved, but device complexity increases
Solution Approach 1:
The vertical extensions and horizontal extensions are designed to nest within or alongside the main siderail structure when not in use. The gap fillers can be stored in compact positions and deployed only when needed to fill specific gaps, thereby increasing coverage area without permanently adding bulky components that would continuously increase device complexity.
Solution Approach 2:
The siderail extensions and gap fillers are designed to serve multiple functions: they can fill gaps between the siderail and headboard/footboard, provide additional patient support surfaces, and adjust to accommodate different patient sizes and bed configurations. This multi-functionality reduces the need for separate specialized components.
3Volume of moving object
If siderails are made retractable underneath bed frame, then space utilization is improved, but ease of operation may be reduced
Solution Approach 1:
The siderail retraction mechanism incorporates self-latching and self-locking features that automatically engage when the siderail is moved to its stowed position underneath the bed frame. This eliminates the need for manual locking operations, thereby reducing operational complexity while enabling compact storage.
Solution Approach 2:
The siderail deployment and retraction mechanism may incorporate mechanical advantage systems such as levers, pulleys, or spring-assisted mechanisms that reduce the physical effort required by the operator. This substitution of simple mechanical aids maintains ease of operation while achieving compact stowage volume.

Function Achieved in This Case
The solution effectively reduces gaps between siderails and bed components, enhancing patient safety by providing comprehensive coverage and easy operation for stowing the siderails when not in use, thus preventing falls and entrapment.

AI summary
A bed siderail has a vertical siderail extension, a horizontal siderail extension, or both. A bed siderail has dual vertical siderail extensions. A bed has gap fillers pivotally mounted to the headboard and/or footboard, either in the manner of a hinge, or by means of a dual axis pivot, to fill gaps between the headboard/footboard and a siderail. A bed siderail has pivotally mounted gap fillers directed toward the headboard, footboard, or an adjacent siderail. A bed has slidably mounted gap fillers. A bed siderail has pivotally mounted gap fillers, to fill a gap between the siderail and a mattress, the gap fillers being either gravity- or cam-activated, or being integrally formed in the siderail support arms. A bed siderail is rotatable from a deployed to a stowed position, and is simultaneously stowed close-into or underneath the bed frame.
