Patient Bed Moveable Frame for Leg Strength Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional patient support systems fail to effectively help patients regain leg strength and independence during recovery, particularly for obese patients, as they require physical lifting, which increases fall risk and is psychologically degrading.
Innovation Solution
A patient support apparatus with an articulated deck that includes a head section, seat section, thigh section, and foot section, featuring a moveable frame that can be adjusted between retracted and extended positions, allowing patients to exercise by moving the frame, with locking mechanisms ensuring safe and controlled movement based on various positional conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional beds are used, then patients can remain in bed for recovery, but patients experience severe deterioration of muscle strength and inability to support full body weight
Solution Approach 1:
The bed incorporates a moveable frame that transitions between retracted and extended positions, enabling dynamic adjustment of the bed configuration. This allows the bed to adapt from a static recovery position to an active exercise position, facilitating leg strengthening while maintaining patient support throughout the transition and exercise process
2Ease of operation
If patients are physically lifted to standing position, then patients can begin ambulation, but fall risk increases and patient psychology is degraded
Solution Approach 1:
The bed enables patients to perform self-exercise by moving the moveable frame between retracted and extended positions. This self-service mechanism allows patients to actively engage their leg muscles without requiring physical lifting or assistance from staff, thereby reducing fall risk and promoting psychological independence while facilitating gradual mobility improvement
3Ease of operation
If bed converts to chair position, then patients can begin standing from foot of bed, but sitting position does not improve leg strength and patients still require physical lifting
Solution Approach 1:
The bed incorporates a moveable frame that transitions between retracted and extended positions, enabling dynamic adjustment of the bed configuration. This allows the bed to adapt from a static recovery position to an active exercise position, facilitating leg strengthening while maintaining patient support throughout the transition and exercise process

AI summary
A patient support apparatus includes a frame. The frame includes a first track and a second track. An articulated deck is coupled to the frame. The articulated deck includes a head section, a seat section, a thigh section, and a foot section. The seat section includes a stationary frame coupled to the frame and a moveable frame that is moveable relative to the stationary frame. The moveable frame includes a first roller that moves along the first track and a second roller that moves along the second track when the moveable frame moves relative to the stationary frame.
