Catheter With Detachable Magnetic Guide Wire Retention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Guide wire retention during catheter placement procedures poses a significant risk to patient safety, as existing strategies fail to effectively prevent retention, leading to complications such as injury, death, and permanent disability due to operator error or inexperience.
Innovation Solution
A catheter equipped with a detachable magnetic attraction mechanism that stabilizes and retains a guide wire made of magnetic material, ensuring it is not inadvertently left inside the patient by magnetically attracting it and keeping it in place until removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional catheter placement procedure is used without additional safety mechanisms, then the procedure is simple and quick, but the risk of guide wire retention in the patient's body increases
Solution Approach 1:
A magnetic marker is introduced as an intermediary element attached to the guide wire. This marker serves as a visible indicator that allows operators to track the guide wire's position and confirm its removal, thereby preventing retention without complicating the catheter structure itself
Solution Approach 2:
The guide wire is equipped with a magnetic marker that can be visually detected. The marker's presence and position provide visual feedback to the operator, enabling confirmation that the guide wire has been completely removed from the patient's body before catheter insertion is completed
2Reliability
If operator experience and concentration are increased to prevent guide wire retention, then guide wire retention decreases, but the requirement for highly trained operators increases procedure complexity and time
Solution Approach 1:
The magnetic marker provides continuous visual feedback to the operator throughout the catheter placement procedure. This feedback mechanism allows operators of any skill level to monitor the guide wire's position and confirm its removal, eliminating the need for highly trained operators to prevent guide wire retention through experience alone
3Loss of information
If a magnetic marker is attached to the guide wire to indicate its position, then the visibility and trackability of the guide wire improve, but the time required for catheter placement increases
Solution Approach 1:
The magnetic marker serves as a simple intermediary that provides visual information about the guide wire's position without requiring additional procedural steps. The marker's presence eliminates the need for frequent manual checks or complex imaging, thereby minimizing time loss while improving position tracking

Function Achieved in This Case
The detachable magnetic attraction mechanism significantly reduces the risk of guide wire retention by ensuring the guide wire is properly exposed and removed, thereby enhancing patient safety and reducing the incidence of related complications.
Implementation Method 1
The magnetically attractive element is provided at the base and is configured to attract the guide wire after the guide wire is inserted through the catheter
