Movable Bougie Tip Angle Control Without Spring Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bougie devices lack features for controlled movement of the tip during tracheal intubation procedures, leading to complexity and inefficiency, particularly in pediatric and neonatal care.
Innovation Solution
A movable tip bougie device with a bougie section and a tip section connected by a silk thread, where a slide button adjusts the tip angle through a recoiled wire and hinge mechanism, allowing manual control and manipulation during intubation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spring mechanism is used to allow movement of the tip, then the tip mobility is improved, but the device complexity increases
Solution Approach 1:
The patent removes the spring mechanism from the device and replaces it with a simpler hinge connection between the tip section and bougie section. The silk thread directly connects the slide button to the tip, eliminating the need for elastic components while maintaining tip mobility through the hinge joint alone.
Solution Approach 2:
Instead of using an active spring mechanism to push the tip into position, the patent uses a passive hinge connection that allows natural movement, with the silk thread serving only to transmit the pulling force from the slide button to the tip for angle adjustment.
2Ease of operation
If the tip angle is fixed, then the device structure is simpler, but the ease of operation during intubation is reduced
Solution Approach 1:
The patent makes the tip angle dynamically adjustable during the intubation procedure. The hinge connection allows the tip section to rotate relative to the bougie section, and the silk thread mechanism enables the operator to adjust the tip angle by pulling the slide button, transforming a static structure into a dynamic one.
Solution Approach 2:
The silk thread acts as an intermediary element that transmits the operator's manual input at the slide button to the tip section, enabling remote control of the tip angle adjustment without requiring direct manipulation of the tip itself.
3Ease of operation
If a complex mechanism is used for tip control, then the control precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent employs simple, inexpensive components that can be easily manufactured and potentially disposed of after use. The hinge connection, silk thread, and slide button are basic elements that do not require precision machining or expensive materials, making the device cost-effective for single-use applications in pediatric and neonatal care.
Solution Approach 2:
The hinge connection provides automatic mechanical advantage for tip angle adjustment. When the slide button pulls the silk thread, the hinge naturally facilitates the rotation of the tip section into the desired position without requiring additional actuators or complex control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides enhanced control and maneuverability of the tip, enabling precise guidance of the endotracheal tube through the vocal cords, reducing procedural complexity and cost, suitable for pediatric and neonatal applications.
Implementation Method 1
The tip section is connected to the bougie section through a hinge and is configured to move backwards toward the bougie section on retraction of the slide button and forward on pushing the slide button forward

AI summary
A movable bougie tip device includes a tip section having a tip, a holder, and a recoiled wire and a bougie section having a bougie, a silk thread, and a slide button located at a first end thereof. The slide button adjusts an angle of the tip relative to the bougie. The silk thread is disposed within a body of the bougie and extends through an outer surface of the tip from the body of the bougie through an opening and protrudes out the tip. The holder holds the silk thread at a distal end of the tip section. The tip bends at an angle ranging from 30° to 90° relative to the bougie, and the recoiled wire prevents kinking of the tip.
