Gastrostomy Catheter Connecting Structure for Smooth Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting structure for gastrostomy catheters and fluid supply tubes often results in uneven fluid flow and leakage due to right-angle fluid passages, and there is a risk of the external holding part becoming embedded in the gastric fistula when the fluid supply tube is pressed in.
Innovation Solution
A connecting structure featuring a C-shaped or U-shaped guide part linked to the external holding part of the gastrostomy catheter, with a cylindrical engaging part that allows the fluid supply tube to connect perpendicularly, preventing pressure on the gastric fistula and ensuring a linear fluid passage for smooth flow and minimizing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid supply tube is pressed strongly into the gastrostomy catheter to ensure connection, then the connection reliability is improved, but the external holding part becomes embedded in the gastric fistula
Solution Approach 1:
The patent introduces a connecting member as an intermediary component between the fluid supply tube and gastrostomy catheter. This connecting member includes a connecting part that engages with the gastrostomy catheter and a tube receiving part that engages with the fluid supply tube, allowing connection without direct pressing force on the external holding part, thus preventing embedding while ensuring reliable connection
2Object-affected harmful factors
If the fluid supply tube is connected perpendicular to the gastrostomy catheter to prevent embedding, then the embedding risk is reduced, but the fluid flow becomes uneven and leakage occurs
Solution Approach 1:
The patent changes the connection dimension by introducing a connecting member that extends in a direction substantially perpendicular to the longitudinal direction of the gastrostomy catheter. The tube receiving part of the connecting member is oriented perpendicular to the catheter's longitudinal axis, allowing the fluid supply tube to connect without pressing the external holding part while maintaining proper fluid flow alignment through the connecting member's internal passage

AI summary
[Issue] To provide a connecting structure for a gastrostomy catheter and a fluid supply tube with which the gastrostomy catheter does not press the body, the flow of fluid is smooth, and leakage is unlikely to occur. [Means of Resolution] A fitting groove is formed on the outer peripheral surface of an external holding part. A connecting member comprises a fitting part, a guide part, and a linking part main body which links the fitting part and guide part, and the fitting part is fitted into the fitting groove with the guide part positioned above an upper opening of the external holding part. Furthermore, a cylindrical engaging part is provided towards the tip end of the tube main body, and the engaging part can engage between the external holding part and guide part in a state in which the tip end of the tube main body is in communication with the upper opening of the external holding part by pushing the engaging part between the external holding part and the guide part so as to introduce the tube main body into the guide part from the open side thereof.
