Angled Fluid Supply Pipe for Stable Air Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air feeding systems for procedures like TATME in small body cavities face challenges in controlling air flow to prevent cavity vibration, requiring continuous pressure measurement and adjustment, and are prone to pipe detachment issues due to improper attachment angles and movement.
Innovation Solution
A pipe design with integrated air feeding and pressure measurement conduits, where tube connection portions are angled between 30° to 60°, preventing pipe detachment and allowing continuous pressure measurement and controlled air flow, even during movement or rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air feeding tube and pressure measurement tube are connected to tube connection portions with an angle of about 90°, then the tubes can be easily connected, but the pipe may be detached from the body wall when the operator attaches the pipe in certain positions (e.g., on the abdomen of a lying examinee)
Solution Approach 1:
The patent changes the angle parameter of the tube connection portions from about 90° to about 45°. This parameter modification allows the pipe to maintain stable attachment to the body wall even when positioned on the abdomen of a lying examinee, while still enabling easy connection of the air feeding tube and pressure measurement tube. The 45° angle optimizes both attachment reliability and operational ease.
2Measurement precision
If two separate tubes (air feeding tube and pressure measurement tube) are used, then continuous pressure measurement and controlled air feeding can be achieved, but the system complexity increases and the pipe detachment risk increases
Solution Approach 1:
The patent merges the air feeding tube and pressure measurement tube into a single integrated pipe structure. The pipe contains both the air feeding conduit and pressure measurement conduit as integrated components, reducing the number of separate tubes from two to one. This integration maintains the capability for continuous pressure measurement and controlled air feeding while simplifying the overall system structure and reducing detachment risk.
Solution Approach 2:
The single pipe structure performs multiple functions: it serves as both the air feeding tube and the pressure measurement tube. The pipe is universally designed to handle both air supply and pressure sensing operations through its integrated conduits, eliminating the need for separate specialized tubes and reducing system complexity.
3Reliability
If the pipe is attached to the body wall for procedures in small body cavities like the rectum, then continuous pressure measurement is possible, but the pipe may be buried or detached due to movement or rotation
Solution Approach 1:
The patent employs asymmetric design in the tube connection portions, with each connection portion having a specific angle of about 45° relative to the pipe axis. This asymmetric angular configuration prevents the pipe from rotating or becoming buried in the body wall during movement, as the angled connections create a stable geometric relationship that resists rotational forces while maintaining continuous pressure measurement capability.

AI summary
A pipe for fluid supply includes: a pipe configured integrally with an air feeding conduit and a pressure measurement conduit; inlets of the air feeding conduit and the pressure measurement conduit; outlets of the air feeding conduit and the pressure measurement conduit; and tube connection portions provided at the respective inlets in the pipe such that an angle between a vertical direction of the respective inlets and a vertical direction of each the respective outlets is 30° to 60°.
