Endoscope Balloon Connector Merging Ducts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic devices face difficulties in inserting the insertion portion into deep body cavities due to complex bending of the intestine, and they have a complex connector system that is prone to connection errors and difficulties.
Innovation Solution
An endoscopic device with a first balloon at the insertion portion and a second balloon on an insertion aid member, where three ducts (communicating with the balloons and a lubricant supply) are connected to a single connector, which is then connected to a balloon control device, either internally or through an external device, to simplify and secure the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple connectors are provided for each duct (first duct, second duct, lubricant duct) to connect to the balloon control device, then each duct can be individually connected, but the number of connectors increases and connection errors may occur
Solution Approach 1:
The patent combines multiple separate connectors (for first duct, second duct, and lubricant duct) into a single integrated connector. This single connector simultaneously connects all three ducts to the balloon control device, reducing the total number of connectors from three to one and eliminating connection errors while maintaining reliable fluid communication.
2Ease of operation
If multiple connectors are provided for each duct, then each connection can be individually established, but the connection process becomes troublesome and time-consuming
Solution Approach 1:
By merging the connection functions into a single connector, the patent enables all three ducts to be connected simultaneously in one operation rather than requiring three separate connection steps. This significantly simplifies the connection process and reduces the time required for setup.
3Device complexity
If a single connector is used to connect all ducts to the balloon control device, then the number of connectors is reduced and connection errors are eliminated, but the connector design becomes more complex
Solution Approach 1:
The single connector is designed with multi-functionality to perform multiple connection tasks simultaneously. It includes multiple connection ports or channels that can connect the first duct, second duct, and lubricant duct to the balloon control device in one unified structure, making it manufacturable as a standard component.
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
This configuration reduces the number of connectors, simplifies the connection process, and eliminates connection errors, improving the ease of use and operability of the endoscopic device by allowing simultaneous connection of the ducts to the balloon control device.
Implementation Method 1
a first balloon at a tip of an insertion portion of an endoscope, and a second balloon at a tip of an insertion aid member... controls supply and suction of a fluid into and from the first balloon and the second balloon

AI summary
A first balloon is fitted to an insertion portion of an endoscope and a second balloon is fitted to an insertion aid member. An end connector of a tube is connected to a balloon control device that supplies and sucks air into and from the first balloon and the second balloon. A duct that communicates with the first balloon, a duct that communicates with the second balloon, and a duct that communicates with a clearance between the insertion portion and the insertion aid member are formed in the end connector.
