Tapered Suction Guide Pipe for Minimally Invasive Sputum Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for suctioning substances like sputum from the respiratory tract, such as mechanical insufflation-exsufflation (MI-E), require technical skills and may not ensure sufficient suction to the upper respiratory tract, risking damage to the respiratory tract if the suction catheter is inserted too far.
Innovation Solution
A suction-target guide pipe with a tapered design connected to a suction device, allowing easy alignment with a human-body-wearable ventilation member to guide the suction target to the upper respiratory tract using negative pressure, facilitating minimally invasive suctioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical insufflation-exsufflation (MI-E) is used to guide sputum to the upper respiratory tract, then minimally invasive suctioning can be performed, but technical skills are required for mechanical operations and settings
Solution Approach 1:
The invention extracts the essential function of guiding sputum to the upper respiratory tract from the complex MI-E device, creating a simple guide pipe that can be manually positioned. This removes the need for complex mechanical insufflation-exsufflation equipment while retaining the core benefit of minimally invasive suctioning.
Solution Approach 2:
The guide pipe acts as an intermediary component between the suction catheter and the patient's respiratory tract. It provides a simple mechanical interface that facilitates sputum guidance without requiring complex operational procedures or technical skills.
2Reliability
If a suction catheter is inserted down to the lower respiratory tract to reach the suction target, then sufficient suction effect can be obtained, but the respiratory tract may be damaged
Solution Approach 1:
The guide pipe serves as an intermediary structure that enables the suction catheter to reach the lower respiratory tract safely. By providing a predefined pathway and structural support, it allows the catheter to navigate to the target location without causing damage to the respiratory tract walls.
Solution Approach 2:
The guide pipe is inserted and positioned beforehand to establish a safe pathway before the suction catheter is introduced. This preliminary action ensures that the catheter follows a predetermined safe route, preventing accidental damage to the respiratory tract during insertion.
3Adaptability or versatility
If sputum is guided to the upper respiratory tract by mechanical insufflation-exsufflation, then minimally invasive sputum suction can be performed, but technical skills are required
Solution Approach 1:
The invention extracts the essential guiding function from the complex MI-E system, creating a standalone guide pipe that achieves minimally invasive sputum guidance without requiring the complex mechanical insufflation-exsufflation procedure or specialized technical skills.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The suction-target guide pipe efficiently directs suction targets to the upper respiratory tract, improving suction efficiency and reducing the risk of respiratory tract damage by enabling easy and minimally invasive removal of substances like sputum.
Implementation Method 1
a suction-target guide pipe that is connected to a suction tube of a suction device includes a guide-pipe main body that includes a connecting portion to be connected to the suction tube and a lid that is provided at an end of the guide-pipe main body and that has an outer peripheral surface and an opening on a distal end side, the outer peripheral surface being formed of a tapered surface whose diameter increases from the distal end to a proximal end
