Oral Positioning Device with Intermediary Teeth Guards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral positioning devices do not adequately protect a patient's incisors from damage during emergency intubation, as they fail to prevent overloading forces when using a laryngoscope to open the mouth, leading to potential incisor breakage or damage.
Innovation Solution
An oral positioning device featuring teeth guards with grooves and an engaging member that accommodates the patient's teeth, along with a breathing tube positioning mechanism to prevent disengagement, utilizing medical-grade plastic and guide passages for secure grip and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a laryngoscope is used to force the patient's mouth open during emergency intubation, then the breathing tube can be inserted quickly, but the patient's incisors may be broken or damaged by overloading force
Solution Approach 1:
The patent introduces a positioning device as an intermediary tool between the laryngoscope and the patient's teeth. The device includes a protective guard that acts as a mediator to absorb and distribute the forcing force during intubation, preventing direct contact between the laryngoscope and the incisors, thus avoiding tooth damage while enabling quick intubation
2Reliability
If an existing oral positioning device is used during intubation, then the breathing tube can be positioned, but the patient's incisors are not protected from damage
Solution Approach 1:
The patent merges the breathing tube positioning function with the teeth protection function into a single integrated device. The positioning device combines a guard structure that protects the incisors with a clamping mechanism that secures the breathing tube, achieving both protection and positioning simultaneously without requiring separate tools
3Object-affected harmful factors
If a protective guard is added to protect the incisors, then the teeth are safeguarded, but the device complexity increases
Solution Approach 1:
The patent designs the positioning device to perform multiple functions: the guard structure protects the incisors from damage, the clamping mechanism positions and secures the breathing tube, and the overall structure provides structural support. By making the device multi-functional, the patent avoids needing separate protective and positioning tools, thus limiting the increase in device complexity

AI summary
An oral positioning device for positioning a breathing tube includes a first teeth guard having a first groove, and a first seat extends from the first teeth guard. The first seat has a first notch. An engaging member has two pivots and a second seat which is engaged with the first seat. The second seat has a second notch which is cooperated with the first notch to form a positioning hole which the breathing tube extends. A second teeth guard has a second groove and two pivotal holes with which the two pivots are pivotably engaged. The first and second seats position the breathing tube in the patient's mouth. The first and second teeth guards protect the patient's teeth from being damaged by of the laryngoscope when opening the patient's mouth.
