Self-Adhering Trauma Bandage With Pass-Through Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wound dressings are inadequate for rapid and effective bleeding control, particularly in emergency situations, as they often require multiple caregivers, can cause tissue damage, and are not suitable for self-application or use in confined spaces, with tourniquets leading to ischemia and tissue damage, and elastic bandages lacking absorbency and ease of use.
Innovation Solution
A self-adhering elastic compression dressing with a pass-through structure and removable absorbent pad, designed for one-handed application, providing adjustable compression and absorbency, suitable for various injury types, including junctional areas, and allowing for additional point pressure using embedded objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct compression is applied to control bleeding, then bleeding control effectiveness is improved, but continuous application by care providers is required which limits their availability for other tasks
Solution Approach 1:
The compression dressing is designed to be self-adhering and self-maintaining. The elastic bandage with adhesive properties sticks to itself and the wound surface, providing continuous compression without requiring ongoing intervention by care providers. The patient can also self-apply and self-monitor the dressing.
Solution Approach 2:
The dressing is pre-configured with the absorbent pad positioned over the wound and the elastic bandage ready for application. The adhesive surfaces are pre-prepared to stick together, eliminating the need for continuous adjustment or reapplication during the compression period.
2Reliability
If extremity tourniquet is used to reduce blood loss, then bleeding control is improved, but ischemia causes extreme pain and soft tissue damage
Solution Approach 1:
The compression force is distributed locally around the wound site rather than creating complete ischemia. The elastic bandage provides graduated compression that is sufficient to control bleeding but allows some blood flow to prevent tissue damage and extreme pain.
Solution Approach 2:
The dressing uses elastic materials that provide dynamic compression rather than fixed high-pressure constriction. The compression level can be adjusted by the tension applied during wrapping, allowing optimization between bleeding control and tissue perfusion.
3Force
If conventional elastic bandage is used for compression, then compression capability is improved, but the bandage shifts during application compromising comfort and compression
Solution Approach 1:
The elastic bandage has self-adhering properties that allow it to stick to itself and the underlying surfaces. As the bandage is wrapped, the adhesive surfaces bond together, preventing shifting and maintaining stable compression without requiring external fastening mechanisms.
4Force
If conventional elastic bandage is used, then compression is provided, but the bandage is clumsy and difficult to self-apply especially with one hand
Solution Approach 1:
The absorbent pad and compression bandage are merged into a single integrated unit. The pad is attached to the bandage, eliminating the need to separately position and secure the pad. This integration simplifies the application process, making it feasible for one-handed or self-application.
Solution Approach 2:
The self-adhering properties allow the patient to independently apply and secure the dressing without assistance. The adhesive surfaces enable the bandage to be wrapped and fixed by the patient themselves, even with limited manual dexterity or in emergency situations.
5Force
If conventional elastic bandage is used, then compression is achieved, but the bandage lacks absorbent qualities
Solution Approach 1:
The absorbent pad and compression bandage are combined into a single multi-functional dressing. The pad provides blood absorption while the elastic bandage provides compression, and both functions are integrated in one application.
Solution Approach 2:
The compression dressing serves multiple functions simultaneously: the absorbent pad absorbs blood and exudate, the elastic bandage provides compression to control bleeding, and the adhesive properties provide securing. This multi-functionality eliminates the need for separate dressings for each purpose.
