Stainless Steel Laryngoscope Blade Double Snap Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal laryngoscope blades provide secure engagement but are costly, making them impractical for disposable use, while plastic blades are less secure and more economical but lack the necessary durability for effective intubation.
Innovation Solution
A resiliently elastically deformable metal blade hook-on fitting for double snap engagement with a correspondingly sized handle hook-on fitting, fabricated from stainless steel, ensuring both sturdiness and elasticity for secure clinical use without excessive cost, applicable to ISO 7376/3 and ISO 7376/1 type laryngoscope blades with integrated light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal laryngoscope blade is used, then secure engagement with the handle is achieved, but the cost increases making it impractical for disposable use
Solution Approach 1:
The blade is divided into two separate parts: a reusable metal handle assembly and a disposable metal blade. The blade can be manufactured separately at lower cost and disposed of after single use, while the expensive handle is reused. This segmentation resolves the contradiction by allowing disposable use of the blade component without requiring the entire assembly to be disposable.
Solution Approach 2:
The thickness of the metal blade is optimized to approximately 1.2 mm, which provides sufficient structural strength for secure engagement while maintaining elasticity for the double snap mechanism. This parameter optimization allows the blade to be both sturdy and cost-effective for disposable use.
2Ease of manufacture
If a plastic laryngoscope blade is used, then cost is reduced for disposable use, but secure engagement and durability are compromised
Solution Approach 1:
The invention creates a disposable metal blade that can be manufactured at relatively low cost through stamping or welding processes, while providing the secure engagement of metal. The blade is designed for single use with a disposable blade pack, combining the benefits of low cost with reliable metal construction.
3Strength
If the blade thickness is increased for sturdiness, then structural strength is improved, but elastic deformability for double snap engagement is reduced
Solution Approach 1:
The blade thickness is precisely controlled at approximately 1.2 mm, which is the optimal parameter that balances structural strength and elastic deformability. This specific thickness allows the blade to be sturdy enough for clinical use while remaining sufficiently elastic to enable the double snap engagement mechanism.
