Adhesive Limb Capture Device for IO Access Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical procedures like intraosseous vascular access, maintaining a patient's limb in a fixed position is crucial to ensure successful access and prevent displacement of the IO needle, which is often compromised by patient movement or accidental bumps, leading to unsuccessful procedures and increased risk in emergency situations.
Innovation Solution
A limb capture device with a base attachable to a surface and an adjustable strap that securely holds a patient's arm or leg in place using an adhesive base and adjustable strap, allowing for customizable fit and secure attachment to the patient's skin or a substrate, reducing the risk of movement during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patient's limb is left free to move, then the patient can respond to physical stimuli and communicate, but the IO needle placement is compromised and may be displaced
Solution Approach 1:
The device segments the limb stabilization function into multiple components: a base unit attached to the patient's body, an adjustable strap that encircles the limb, and a positioning mechanism that holds the limb in the required position. This segmentation allows the limb to be secured without restricting the patient's overall mobility or causing discomfort.
Solution Approach 2:
The strap incorporates an adjustable mechanism that allows dynamic modification of the opening size and positioning during the procedure. The engagement member can be moved to change the side of the opening, and the strap can be tightened or loosened as needed, providing adaptability while maintaining stability during IO needle placement.
2Reliability
If the limb is secured tightly to prevent movement, then IO needle placement is successful, but the device becomes complex and difficult to adjust
Solution Approach 1:
The device extracts the essential stabilization function into a simple strap mechanism that can be independently adjusted. The engagement member and opening structure are separated from the base, allowing the strap to be adjusted without complicating the overall device. This extraction simplifies the adjustment mechanism while maintaining effective limb securing.
Solution Approach 2:
The device utilizes parameter changes in the strap configuration, specifically the size of the opening and the position of the engagement member, to adapt to different limb sizes and positions. By changing these parameters through simple adjustments, the device can securely hold various limbs without requiring complex reconfiguration.
3Adaptability or versatility
If the strap opening is made large to accommodate different limb sizes, then adaptability is improved, but the limb cannot be held securely in position
Solution Approach 1:
The strap incorporates an adjustable mechanism that allows dynamic modification of the opening size during the procedure. The engagement member can be moved to change the side and size of the opening, enabling the same strap to accommodate different limb sizes while maintaining secure positioning for each specific patient and procedure.
Solution Approach 2:
The device allows preliminary adjustment of the strap opening to the appropriate size before securing the limb. The engagement member can be positioned in advance to create the correct opening configuration, ensuring that when the limb is placed, it can be securely held in the required position without requiring further adjustment during the procedure.
