Unibody Auscultation Interface for Mechanical Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for isolating and clarifying pulmonary breath sounds during mechanical ventilation, such as in-line and off-line approaches, either encumber the mechanical ventilation system or require disassembly, failing to provide clear auscultation without interfering with the ventilation process.
Innovation Solution
A seamless, leak-proof, non-metallic auscultation interface that frictionally connects to the endotracheal tube and breathing circuit, allowing non-adherent contact with a stethoscope, eliminating the need for connectors and enabling continuous use without system disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an in-line approach with connectors is used to attach a stethoscope to the endotracheal tube, then breath sounds can be isolated and clarified, but the mechanical ventilation system becomes encumbered and more complex
Solution Approach 1:
The patent combines the stethoscope attachment mechanism directly with the endotracheal tube structure, eliminating separate connectors. The stethoscope interface is integrated into the tube assembly, allowing breath sound isolation without adding external components that would encumber the ventilation system.
Solution Approach 2:
The endotracheal tube assembly is designed to serve multiple functions: maintaining airway patency, delivering ventilation, and enabling auscultation. The integrated design allows the same structure to fulfill both ventilation and auscultation purposes without requiring separate specialized components.
2Measurement precision
If connectors are used to attach the stethoscope, then breath sounds can be auscultated, but the system requires assembly and disassembly which interrupts continuous use
Solution Approach 1:
The stethoscope interface is merged with the endotracheal tube as a single integrated assembly. This eliminates the need for separate connectors that would require assembly and disassembly, allowing the system to remain continuously connected while enabling clear breath sound auscultation throughout the procedure.
3Measurement precision
If the stethoscope chest piece is removed and replaced with a drum, then breath sounds can be transmitted, but the device complexity increases and the stethoscope becomes non-standard
Solution Approach 1:
Instead of modifying the stethoscope by removing its chest piece and adding complex drum mechanisms, the patent extracts only the essential auscultation function and integrates it directly into the endotracheal tube assembly. This allows breath sound transmission without requiring non-standard stethoscope modifications.
