Patient Repositioning Sheet and Sling Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient repositioning methods in medical environments often require caregivers to choose between repositioning sheets and lift/sling systems, which can be cumbersome and inefficient, especially when patients need to be moved over long distances or require frequent repositioning to prevent pressure ulcers.
Innovation Solution
A patient repositioning apparatus that functions as both a sheet and a sling, featuring a high-friction upper surface for comfort and a low-friction lower surface for easy sliding, along with adjustable strap members and handles for secure handling and lifting, allowing for flexible repositioning and transfer without changing the sheet beneath the patient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a repositioning sheet is used for short-distance patient movement, then the repositioning can be performed quickly and efficiently without large lifting equipment, but the sheet cannot be used for long-distance transfers requiring mechanical lifting
Solution Approach 1:
The patient handling sheet is designed to serve multiple functions: it can be used as a traditional repositioning sheet for short-distance movements by sliding, or as a sling for long-distance transfers when connected to a patient lift. The sheet includes attachment points for connecting to lifting equipment, transforming it from a single-function repositioning tool into a universal device that adapts to both manual sliding and mechanical lifting scenarios.
2Adaptability or versatility
If a sling with patient lift is used for long-distance patient transfer, then the transfer can be performed effectively, but the sheet must be changed to use the sling
Solution Approach 1:
The invention merges the functions of a repositioning sheet and a sling into a single integrated device. The patient handling sheet incorporates attachment points and structural features that allow it to function as both a sliding sheet and a sling for mechanical lifting. This eliminates the need to change sheets between different types of patient handling operations, reducing complexity and improving workflow efficiency.
3Ease of manufacture
If caregivers manually move heavy patients, then no equipment is needed, but the practice becomes strenuous and dangerous for caregivers
Solution Approach 1:
The patient handling sheet acts as an intermediary between the patient and the caregiver, or between the patient and the lifting equipment. When used with a patient lift, the sheet serves as the connecting medium that distributes the patient's weight and facilitates safe transfer. This intermediary role reduces direct physical strain on caregivers while maintaining operational simplicity.

AI summary
A patient repositioning apparatus doubles as a repositioning sheet and a sling. The repositioning apparatus includes a sheet with an upper surface and an opposing lower surface and defines an outer periphery that has opposing side edges. The upper surface of the sheet has an upper surface material, and the lower surface of the sheet has a lower surface material that is formed from a relatively low-friction material as compared to the upper surface material. The handles are disposed along the opposing side edges of the sheet, and the strap members are attached to the sheet and distributed across both opposing side edges. Each of the strap members includes a strap portion that forms a bight in the strap member.
