Multi-Layer Patient Movement Device for Single-Caregiver Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bedridden patients, especially larger or heavier ones, require assistance from multiple caregivers to adjust their position, which is often not available, leading to pressure ulcers and other complications.
Innovation Solution
A movement device with layers of low friction, durable, and breathable textile materials, allowing a single caregiver to adjust the position of a bedridden patient by pulling on handles, reducing the need for additional assistance and minimizing pressure ulcer risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional transfer sheets are used to assist a caregiver in maneuvering a patient, then the patient can be moved, but more than one person is still required, especially for heavier patients
Solution Approach 1:
The movement device acts as an intermediary tool between the caregiver and patient. It includes a first layer of low friction material that contacts the bed surface, a second layer of durable material for structural support, and a third layer of delicate material that contacts the patient's skin. Handles are attached to the device, allowing a single caregiver to pull and maneuver the patient effectively without requiring additional personnel.
2Reliability
If multiple caregivers are used to maneuver heavier patients, then patient safety is improved, but resource availability and cost increase
Solution Approach 1:
The invention changes the friction parameter between the movement device and bed surface by using low friction material on the first layer. This parameter change allows a single caregiver to generate sufficient force to move heavier patients safely, effectively compensating for reduced human resources while maintaining patient safety.
3Ease of operation
If a movement device with low friction material is used, then ease of pulling is improved, but friction with the bed surface decreases which may cause slipping
Solution Approach 1:
The movement device applies local quality by having different material properties in different layers. The first layer has low friction material for easy pulling, while the second layer provides durable structural support, and the third layer has delicate material for patient comfort. This layered approach with differentiated local properties resolves the contradiction between ease of pulling and sufficient friction.
