Hospital Chair Bed Drop Foot Section for Side Egress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hospital beds lack the ability to easily convert into chair configurations, making it difficult for patients to elevate from a supine position to a sitting or standing position, which can hinder circulation and mobility.
Innovation Solution
A hospital bed with a base, lifting mechanism, rotating frame, and articulating patient support surface that includes a back panel, seat panel, and leg panel, allowing for conversion into a side-egress chair configuration, where the leg panel can detach and pivot to facilitate easy patient egress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hospital beds are used to support patients in supine position, then patient comfort and circulatory support are improved, but patient mobility and ability to transition to sitting or standing position deteriorate
Solution Approach 1:
The patient support surface is divided into multiple articulating segments including back panel, seat panel, and leg panel that can move independently relative to each other. This segmentation allows the bed to transform from a rigid supine support structure to a flexible multi-position configuration that facilitates patient mobility while maintaining comfort during transitions
Solution Approach 2:
The bed incorporates dynamic components including a lifting mechanism with scissors lift, rotating frame, and articulating panels that enable continuous motion between supine and chair configurations. These dynamic elements allow the bed to adapt its shape and position to assist patient movement while providing stable support throughout the transition process
2Ease of operation
If hospital bed is converted to chair configuration to improve patient comfort and activity, then patient ability to sit and engage in activities is improved, but difficulty for some patients to get out of bed persists
Solution Approach 1:
The leg panel is divided into first and second sections that can separate from each other during the egress process. This segmentation allows the leg support to detach and pivot independently, creating clear space for patient feet and legs during the transition from sitting to standing position, thereby facilitating easier patient egress
Solution Approach 2:
The leg panel second section is configured to pivot downwardly away from the first section prior to the patient attempting to stand. This preliminary action of detaching and repositioning the leg panel creates optimal geometry for patient egress before the patient initiates the standing motion, reducing the effort required to exit the bed

AI summary
A hospital bed convertible to a side egress chair bed includes a base having opposite end portions; a lifting mechanism secured to the base between the end portions; a rotating frame mounted on the lifting mechanism and configured to rotate horizontally relative to the base; and a patient support surface pivotally secured to the rotating frame. The patient support surface includes a back panel, a seat panel, and a leg panel that are configured to articulate relative to each other from a co-planar configuration to a chair configuration. The leg panel includes a first section pivotally connected to the seat panel and a second section that is separable from the leg panel first section.
