Pelvic Sling with Integrated Velcro for Fracture Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for stabilizing a fractured pelvis in emergency situations require complex placement and adjustment of strap mounting pieces, which can be time-consuming and challenging for untrained users, and lack sufficient adjustability to provide adequate tension.
Innovation Solution
A wide belt-like device with integrated Velcro fastener material for adjustable tension, allowing for easy application and secure fitting around the pelvis without the need for separate strap placement, and optional use as a cervical support collar with inflatable bladders and chin rest for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate strap mounting piece is used to provide adjustability, then the device can accommodate different pelvic circumferences, but the device complexity increases and requires multiple placement steps
Solution Approach 1:
The patent combines the strap mounting piece functionality directly into the main body of the device. The fastening elements are integrated into the belt-like structure, eliminating the need for separate attachment steps. This merging reduces device complexity while preserving the adjustability feature through integrated loops and fastening points distributed along the main body.
Solution Approach 2:
The main body of the device is designed to serve multiple functions: it provides the primary structural support, contains integrated fastening points for adjustment, and eliminates the need for separate strap mounting pieces. This multi-functionality approach reduces the number of components and simplifies the overall application process while maintaining adaptability.
2Adaptability or versatility
If a separate strap is used to provide tension adjustment, then the device can be customized for different patients, but the ease of operation decreases due to requiring precise placement
Solution Approach 1:
The device is pre-configured with multiple fastening points and loops integrated into the main body during manufacturing. This preliminary arrangement of fastening elements eliminates the need for operators to make precise placement decisions during application. The tension adjustment mechanism is prepared in advance, allowing users to simply select and engage the appropriate fastening point without complex positioning requirements.
3Ease of manufacture
If the strap mounting piece is removable for reuse, then the device can be cost-effective, but the time required for rearrangement increases
Solution Approach 1:
The fastening elements are permanently integrated into the main body structure, eliminating the need for removal and rearrangement of separate strap mounting pieces. This merging of components allows the entire device to be reused as a single unit, significantly reducing the time required for preparation between uses while maintaining cost-effectiveness through durable construction.

AI summary
A hip-girdling pelvic sling device for maintaining a desired amount of tension surrounding a person's hips and pelvis to securely support and stabilize a pelvis that has been fractured. Areas of mating types of fastener material such as mating hook-bearing fastener material and loop pile fastener material are arranged on the device to enable a strap to be secured at various effective lengths to provide a wide range of adjustability. The device may include inflatable bladders, stays, and a chin support and may be wrapped around a patient's neck as a cervical support collar.
