Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools and methods for tracheal stenosis dilatation are heterogeneous, difficult, expensive, and require a team of experts, and there is a need for a kit that can dilate the whole spectrum of tracheal stenosis while maintaining patient ventilation.
Innovation Solution
A tracheal dilator kit comprising a standard tracheal dilator (TD-S) and quadritube tracheal dilator (TD-Q) that includes a dilator tip, endotracheal tube cuff, dilation balloon, ETT cuff inflator tube, pressure measurement tube, balloon inflator tube, and ventilation lumen, allowing for graduated dilatation from narrow to larger stenosis sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current heterogeneous tools and methods are used for tracheal stenosis dilatation, then treatment capability is achieved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent combines multiple separate tools (dilator, balloon, cuff, inflator tubes) into a single integrated quadritube device. The four-lumen tube structure merges the functions of tracheal dilation, cuff inflation, balloon inflation, and pressure monitoring into one unified device, eliminating the need for multiple separate instruments and reducing operational complexity.
Solution Approach 2:
The quadritube device performs multiple functions simultaneously: it serves as a tracheal dilator, endotracheal tube, balloon catheter, and pressure monitoring line all within one device. This multi-functionality allows a single device to replace multiple specialized tools, simplifying the overall treatment process while maintaining comprehensive treatment capability.
2Adaptability or versatility
If current tools are used for tracheal stenosis dilatation, then treatment is performed, but the process becomes difficult and requires multiple experts
Solution Approach 1:
By merging the functions of dilation, ventilation, cuff inflation, and pressure monitoring into a single integrated device, the operational process becomes simpler and more coordinated. The integrated design eliminates the need for multiple experts to manage separate instruments, as one device can be managed by a single operator while maintaining all necessary treatment functions.
Solution Approach 2:
The multi-functional quadritube device allows a single operator to perform multiple tasks simultaneously - dilating the trachea, maintaining ventilation, inflating the cuff, and monitoring pressure - without requiring coordination between multiple specialists. This universality significantly improves ease of operation while preserving comprehensive treatment capability.
3Adaptability or versatility
If a comprehensive kit is designed to handle all stenosis sizes, then adaptability improves, but device complexity increases
Solution Approach 1:
The quadritube device is designed with universal applicability to handle the entire spectrum of tracheal stenosis sizes through its four-lumen configuration. The device can accommodate various stenosis diameters (from 2mm to 6mm) while maintaining the same basic structure and function, eliminating the need for multiple specialized devices for different size ranges.

AI summary
Methods, systems, and apparatus are disclosed herein for a tracheal dilator kit (TDK), comprising a set of Tracheal dilators while maintaining the patient's ventilation, comprising a quadritube Tracheal dilator (TD-Q) for very tight Tracheal stenosis (<6 mm) and a standard Tracheal dilator (TD-S) for tracheal stenosis dilatation of less tight stenosis. The standard tracheal dilator (TD-S) is a three-lumen tube which includes an endotracheal tube with a rigid dilator tip with a ventilatory lumen, an endotracheal tube (ETT) cuff, and a dilation balloon. The quadritube dilator is a four-lumen tube with a first end and second end, where the dilator tip is located on the first end. The ETT cuff is located on the first end, the dilation balloon is located on the first end.
