Adjustable Limb Restraints for Stable Patient Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for maintaining patient position during surgical procedures are inadequate, particularly for obese or oversized patients, as they fail to securely retain limbs in a consistent and safe manner due to loosening sheets or insufficient table size accommodation.
Innovation Solution
The use of adjustable restraint devices, including flexible cuffs and rails, that can be customized and locked into various positions to securely hold patient limbs, allowing for adjustable and reusable solutions that accommodate different patient sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If folding or cushioning techniques of sheets are used to hold patient limbs, then the technique is simple to implement, but the position consistency and reliability deteriorate because sheets can loosen allowing limb movement
Solution Approach 1:
The patent employs disposable sheet assemblies that are pre-configured with adhesive portions and cushioning elements. These single-use components are attached to the surgical table and provide reliable limb positioning without the loosening problems of reusable sheets. The disposable nature ensures consistent performance for each procedure while eliminating the need for complex adjustment mechanisms.
2Device complexity
If conventional sheet techniques are used, then the device complexity is low, but the adaptability to different patient sizes deteriorates, particularly for obese or oversized patients
Solution Approach 1:
The patent incorporates adjustable and reconfigurable sheet assemblies that can be dynamically adapted to different patient sizes and limb configurations. The sheets include adjustable straps, repositionable cushioning elements, and flexible positioning components that can be customized for each patient's anatomical dimensions, thereby achieving versatility without excessive complexity.
Solution Approach 2:
The positioning system is divided into modular components including separate sheet assemblies, cushioning elements, adhesive portions, and restraint components. This segmentation allows each element to be independently adjusted and configured to accommodate various patient sizes and surgical positions, enhancing adaptability while maintaining manageable system complexity.
3Loss of substance
If reusable restraint devices are used, then the loss of substance is reduced, but the ease of operation and quick adjustment deteriorate
Solution Approach 1:
The reusable restraint devices are pre-configured with pre-attached cushioning elements, pre-positioned adhesive portions, and pre-assembled modular components. This preliminary preparation eliminates the need for complex assembly operations during surgery, allowing medical staff to quickly adjust and secure patient limbs while maintaining the benefits of reusable materials.

AI summary
Some systems, devices and methods detailed herein provide adjustable restraint device maintaining a selected position of a person relative to a support structure, for example, to maintain a safe and customizable patient position during a surgical procedure or during medical transport. For example, in particular embodiments, the adjustable restraint devices can be releasably lockable at a customized position along the surgical table and can be conveniently manipulated to a curved or other customized configuration (e.g., to engage with a patient's limb before being releasably locked into that particular customized configuration.
