Harness Attachment Hook for Junctional Tourniquet Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tourniquet deployment methods are difficult to obtain and deploy during traumatic moments, making it challenging to control bleeding effectively in emergency situations.
Innovation Solution
A harness attachment hook system that secures a strap around junctional areas using a hook mechanism with a specific pressure profile, integrating with vests and body armor for easy deployment and use, allowing for quick application of pressure to control blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional tourniquet is used to control bleeding, then blood flow can be stopped, but it is difficult to obtain and deploy during traumatic moments
Solution Approach 1:
The tourniquet system is pre-integrated into the harness structure with the tourniquet mechanism already positioned and ready for immediate deployment. The strap and hook assembly is pre-configured so that users can quickly activate the tourniquet by simply pulling the strap, eliminating the need to assemble or locate separate tourniquet components during emergency situations.
Solution Approach 2:
The tourniquet functionality is merged with the harness structure by integrating the strap, hook, and pressure application mechanism into a unified system. The harness strap serves dual purposes as both a carrying/ support element and as the tourniquet application element, while the hook integrates with the harness attachment points to enable quick deployment without requiring separate tourniquet devices.
2Ease of operation
If a harness attachment hook system is used to enable quick deployment, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The hook mechanism serves multiple functions within the harness system: it acts as an attachment point for the tourniquet strap, provides a leverage point for securing the strap around body extremities, and enables quick release through its engagement and disengagement capabilities. This multi-functionality reduces the need for separate specialized components, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The attachment mechanism is segmented into distinct functional elements: the hook component, the strap with integrated pressure profile, and the mounting interface. This segmentation allows each component to be optimized for its specific function while maintaining simplicity in the overall assembly. The modular nature of the segmented design facilitates easy manufacturing and assembly without requiring complex integrated structures.

AI summary
Described embodiments provide systems and methods for an attachment mechanism for attaching a strap around a body extremity. The attachment mechanism includes a hook, a first channel, and a second channel. The hook includes a first longitudinal axis and coupled to the strap at a first region of the hook. The first channel allowing the attachment mechanism to receive the strap. The second channel extending from the first channel and having an opening allowing the attachment mechanism to secure the strap, the opening extending along a second longitudinal axis, the second longitudinal axis forming an angle of less than ninety degrees with the first longitudinal axis. The strap is coupled to a harness. The strap includes a first portion, an attachment portion attached to the first portion, a main portion attached to the attachment portion; and an elastic portion attached to the main portion.
