Adjustable Endotracheal Tube Locking With Integrated Bite Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endotracheal tube holders cause discomfort due to cheek pads, loosen over time, and lack a bite block to keep the mouth open, compromising the positioning of the distal end of the endotracheal tube.
Innovation Solution
A device featuring a frame with a radial tracking portion and an adjustable locking mechanism, including a bite block and a swivel lock portion, to securely fasten the endotracheal tube at a desired position within the trachea, using a semi-rigid polymer for the bite block and adjustable clamp for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cheek pads are added to protect the patient's cheeks from irritation, then patient protection is improved, but patient comfort deteriorates due to discomfort caused by the pads
Solution Approach 1:
The patent removes the cheek pads entirely from the design, extracting the harmful element that caused discomfort while maintaining cheek protection through the frame structure itself. The radial track portion and frame provide structural support without requiring additional padding that would cause irritation.
Solution Approach 2:
The patent converts the potential harm of rigid frame structures irritating the cheeks into a benefit by designing a frame that naturally protects the cheeks without requiring soft pads. The frame's geometry and positioning system provide protection through proper placement rather than through contact with soft materials.
2Ease of operation
If a conventional locking mechanism is used, then initial positioning is achieved, but the positioning loosens over time compromising ETT placement
Solution Approach 1:
The patent employs a dynamic locking mechanism that allows for initial positioning and then maintains that position through a self-adjusting or secureable feature. The swivel lock portion enables the user to lock the ETT at the desired position, preventing it from loosening over time while maintaining the ability to adjust if needed.
3Reliability
If the frame structure is made rigid for stability, then positioning stability is improved, but patient comfort deteriorates due to lack of softness in the mouth
Solution Approach 1:
The patent applies different material properties to different parts of the device: the frame structure remains rigid for stability and positioning, while the bite block is made of a softer material to provide patient comfort in the mouth. This local differentiation of material quality allows both stability and comfort to coexist.
4Device complexity
If no bite block is included to keep the mouth open, then device complexity is reduced, but the patient may bite themselves or occlude the ETT
Solution Approach 1:
The patent merges the bite block function with the existing frame structure, integrating it as part of the overall device rather than requiring a completely separate component. The bite block is positioned and secured within the frame system, combining structural support with the mouth-opening function.
