Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separation of tubes and catheters connected by high viscosity contrast agents is physically demanding due to the high rotational force required, making it difficult for users to efficiently disconnect and reconnect them for repeated medical imaging procedures.
Innovation Solution
A guider device with a cylindrical body and wing portions that allows for easy rotation and separation of the tube from the catheter, featuring an insertion groove, fixing groove, and protruding wing portions for reduced effort and improved handling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tube and catheter are separated by applying grasping power with bare hands or using medical forceps, then the separation process can be performed, but the high viscosity of the contrast agent makes it physically difficult and requires great effort
Solution Approach 1:
The guider acts as an intermediary tool between the user and the tube-catheter connection. It includes a body portion that fits onto the tube and wing portions that provide leverage, allowing the user to rotate and separate the tube from the catheter without directly applying force to the connected components. This mediator amplifies the user's input force and applies it effectively to overcome the high viscosity resistance.
Solution Approach 2:
The wing portions extend radially outward from the body portion, creating a lever arm in a dimension perpendicular to the axis of the tube. This dimensional extension allows the user to apply rotational force at a greater radius, effectively reducing the effort needed to overcome the high viscosity contrast agent that resists separation.
2Productivity
If the tube and catheter are disconnected and reconnected for repeated medical imaging, then multiple imaging procedures can be performed, but the process is time-consuming and inefficient due to the difficulty of separation
Solution Approach 1:
The guider serves as a dedicated intermediary tool specifically designed for the separation operation. By providing ergonomic wing portions and a proper fit onto the tube, it enables rapid and easy separation, reducing the time needed for this repeated operation during medical imaging procedures.
Solution Approach 2:
The guider is designed to be self-retaining through the engagement of the body portion with the tube and the fixing groove with the protrusion. This self-service design eliminates the need for additional tools or complex manipulation steps, allowing the user to quickly perform separation and reconnection operations.
3Ease of operation
If a dedicated guider for separating tube from catheter is introduced, then separation becomes easy without great effort, but the device complexity increases
Solution Approach 1:
The guider is segmented into distinct functional portions: the body portion that interfaces with the tube and the wing portions that provide user interaction. This segmentation allows each part to be optimized for its specific function while keeping the overall structure simple and manufacturable.
Solution Approach 2:
The body portion is designed with a through space and engagement features that can accommodate standard tubes used in medical imaging. The wing portions provide both leverage for rotation and ergonomic grip. This multi-functional design achieves complex separation capability with relatively simple structural elements.
