Blood Shunt Housing With Flow Regulation and Removable Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shunting devices for transferring blood from the arterial to the venous system often cause uncontrolled blood flow, leading to complications such as coagulation and clogging, which can overwhelm the body's ability to maintain homeostasis during medical procedures.
Innovation Solution
A shunting system with a two-component housing that includes an adjustable trigger to regulate blood flow, a blood reservoir for stabilizing pressure, and a removable blood filter, connected by friction fits to ensure easy access and assembly, minimizing the risk of component failure and allowing for controlled blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shunting devices are used to transfer blood from arterial to venous system, then blood flow transfer is achieved, but uncontrolled blood flow occurs leading to coagulation and clogging
Solution Approach 1:
The patent implements a collapsible tubing design that dynamically changes its lumen cross-sectional area in response to external compression forces. The tubing includes a collapsible section with circumferential reinforcement that allows controlled collapse to regulate blood flow rate, preventing uncontrolled flow that leads to coagulation and clogging while maintaining reliable blood transfer from arterial to venous system
Solution Approach 2:
The patent changes the physical parameter of the tubing lumen by applying external compression forces to reduce the cross-sectional area of the collapsible section. This parameter change directly controls the blood flow rate through the shunting device, ensuring flow remains within safe limits to prevent coagulation and clogging while maintaining effective blood transfer
2Ease of operation
If shunting devices are used during medical procedures, then blood flow regulation is needed, but device complexity increases with additional components
Solution Approach 1:
The patent divides the shunting device into distinct functional segments: an arterial connection section, a collapsible tubing section with flow regulation capability, a venous connection section, and a filter section. This segmentation allows each component to perform its specific function independently, simplifying the overall device structure while maintaining ease of operation for blood flow regulation
Solution Approach 2:
The patent introduces a filter as an intermediary component within the shunting device that captures debris and prevents it from entering the venous system. This intermediary element addresses the complexity of preventing coagulation and clogging without requiring complex control mechanisms, as the filter passively performs the protective function while blood flows through the regulated collapsible tubing

AI summary
A shunting system includes a housing through which blood flow is regulated when passing therethrough, for example, from the arterial side to the venous side of the circulatory system. The housing is easily separable into housing components, the separability providing for access to inner components including a blood filter, which is easily removable from a connector disc, the blood filter and connector disc held in place in the housing when the housing components are coupled.
