Bi-valve Peripheral IV Catheter Back-flow Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical catheter systems face challenges in preventing back-flow contamination and blood spill during peripheral IV or arterial line access, which can compromise catheter security and pose risks to both patients and healthcare providers.
Innovation Solution
An adaptable internal bi-valvular secure system is integrated into medical catheters, utilizing a silicon rubber, plastic, and stainless metal or Teflon-made spiral structure to create a sterile access point that automatically opens and closes to prevent back-flow, allowing secure connection and manipulation of catheters without exposing healthcare providers to biological materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a peripheral IV or arterial line is accessed using conventional catheter systems, then catheter insertion can be performed, but back-flow contamination and blood spill occur compromising catheter security and posing risks to patients and healthcare providers
Solution Approach 1:
The bi-valvular system is pre-installed within the catheter structure, creating a preliminary protective barrier that actively prevents back-flow contamination and blood spill before these harmful events can occur. The valves are positioned to intercept and redirect potential back-flow, neutralizing the harmful effect before it compromises catheter security or exposes personnel to biological materials.
Solution Approach 2:
The bi-valvular system acts as an intermediary component between the catheter lumen and the external environment. The valves serve as a mediating structure that controls fluid flow direction, allowing forward flow while blocking reverse flow, thus preventing direct contact between blood/biological materials and the external environment or healthcare providers.
2Ease of operation
If conventional catheter systems are used, then catheter insertion is possible, but healthcare providers are exposed to biological materials requiring rapid manipulation that increases contamination risk
Solution Approach 1:
The bi-valvular system is pre-configured within the catheter, eliminating the need for rapid post-insertion manipulation to secure the catheter. The valves are already in position to prevent back-flow, allowing healthcare providers to work at a normal, controlled pace without the urgency of preventing contamination, thereby reducing exposure risk while maintaining ease of operation.
Solution Approach 2:
The bi-valvular system provides self-protection functionality, automatically preventing back-flow and contamination without requiring active intervention or rapid manipulation by the healthcare provider. The system serves itself by inherently blocking reverse flow, allowing providers to manipulate the catheter at their own pace without compromising safety.
3Reliability
If a bi-valvular system is integrated into the catheter, then back-flow prevention and sterile access are improved, but device structure becomes more complex
Solution Approach 1:
The bi-valvular system is nested within the existing catheter structure, with the valves integrated into the catheter wall or lumen. This nesting approach allows the complex valvular mechanism to be contained within the relatively simple overall catheter form, minimizing external complexity while maintaining internal protective functionality. The valves are positioned concentrically or linearly within the catheter body.
Solution Approach 2:
The bi-valvular system utilizes flexible valve components that can be constructed from thin, compliant materials allowing the complex internal structure to be compact and integrated within the catheter. The flexible nature of the valves enables them to conform to the catheter geometry, reducing overall device complexity while maintaining effective back-flow prevention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents contamination and blood spill, ensuring a sterile environment for catheter insertion and manipulation, reducing the risk of exposure for both patients and healthcare providers while maintaining catheter security and ease of use in stressful scenarios.
Implementation Method 1
The Teflon made or stainless mini spiral spring band allows the sliding mechanism of the valve to be activated with the appropriate resistance support when medications and/or fluids are administered, and to be deactivated when the IV, arterial line or any other medical systems catheter is capped and closed in between uses.
