Endotracheal Tube Stabilizer with Rotating Wing Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endotracheal tube stabilization devices are not well-suited for patients with maxillofacial burns, as they can cause tissue damage and are difficult to secure due to adhesive tape's reduced adhesiveness and the need for frequent adjustments, leading to potential extubation and infection risks.
Innovation Solution
A novel endotracheal tube stabilization device featuring a semi-rigid endotracheal tube holder with a rotating wing plate and adjustable strap assembly, using burn-compatible materials to minimize pressure on facial tissues and facilitate easy adjustment and replacement, incorporating a bite block to distribute bite pressure and prevent dental damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is used to secure the endotracheal tube, then the tube can be fixed to the patient, but the tape loses adhesiveness due to warm humidified gases and burn patient conditions, increasing the risk of extubation
Solution Approach 1:
The patent replaces the adhesive-based mechanical fixation system with a purely mechanical strap system. The strap assembly uses adjustable straps that wrap around the patient's head and secure to the tube holder, eliminating dependence on adhesive properties that deteriorate under heat and moisture conditions. This mechanical substitution ensures reliable tube fixation without being affected by warm humidified gases or burn patient conditions.
Solution Approach 2:
The patent changes the fixation mechanism from adhesive-based to mechanical strap-based, fundamentally altering how the tube is secured. The strap assembly allows for adjustable tension and secure anchoring points that do not rely on chemical adhesion, thereby maintaining fixation reliability despite changes in environmental parameters such as temperature and humidity.
2Reliability
If straps or harnesses are used to secure the endotracheal tube, then adhesive tape issues are avoided, but the straps exert pressure against facial tissue causing irritation and potential tissue damage
Solution Approach 1:
The patent applies local quality by using a bite block made of soft, compliant material specifically at the oral cavity interface. This localized soft material distributes bite forces and reduces pressure on the lips and cheeks, preventing tissue damage while maintaining secure tube fixation. The rest of the strap system maintains its mechanical strength for reliable fixation.
Solution Approach 2:
The patent incorporates a bite block as a cushioning element that is positioned beforehand to protect the patient's facial tissue from pressure and irritation. The soft material of the bite block acts as a buffer between the rigid tube holder and the patient's soft tissues, preventing damage before it occurs.
3Reliability
If conventional straps are used to secure the endotracheal tube, then fixation is achieved, but visual examination of skin beneath straps is difficult and infection or necrosis can occur
Solution Approach 1:
The patent segments the strap system into distinct components with specific functions: the bite block for oral protection, the tube holder for tube securing, and the adjustable straps for head fixation. This segmentation allows for better airflow and reduced pressure concentration at any single location, facilitating visual examination and reducing infection risk while maintaining fixation reliability.
4Reliability
If twill tape is used to tie the endotracheal tube, then fixation is achieved without adhesive issues, but the process of replacement or adjustment is tedious and time consuming
Solution Approach 1:
The patent implements a dynamic adjustment system using adjustable straps with quick-release mechanisms. This allows the tube holder to be easily repositioned or removed by simply loosening the straps, eliminating the need to cut or untie twill tape. The dynamic strap system maintains secure fixation during use but enables rapid adjustment or replacement when needed, significantly reducing time loss.
