Auxiliary Visible Light Rod for Difficult Airway Intubation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tracheal intubation methods face challenges with patients having poor intubation conditions, leading to high failure rates, prolonged procedures, and increased risk of infection and discomfort due to reliance on inaccurate CO2 monitoring and lack of intuitive visualization tools.
Innovation Solution
An auxiliary visible light rod for multisource end-expiratory CO2 monitoring, equipped with a handle, pump body, medicine compartment, and rod body, featuring a camera, atomizing head, and illumination, which allows for direct visualization of the trachea and anti-inflammatory agent delivery to reduce infection risk and improve intubation accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct laryngoscope intubation is used under direct vision, then the intubation method is simple and equipment is minimal, but it fails for patients with poor intubation conditions (small jaw, short thyromental distance, raised glottis, limited neck movement) leading to high failure rates and prolonged procedures
Solution Approach 1:
The patent introduces a light rod as an intermediary tool between the direct laryngoscope and the trachea. This light rod provides both illumination and structural guidance, serving as a mediator that facilitates visualization and access in difficult airways without requiring complex equipment like video laryngoscopes or fiberoptic scopes.
Solution Approach 2:
The patent adds the dimension of direct visual observation by incorporating a camera and display screen, transforming the traditional tactile-based intubation guidance into a visual-based system. This dimensional change allows operators to directly observe the internal environment of the airway, significantly improving success rates for difficult intubations.
2Ease of operation
If existing light rods are used to solve difficult intubation problems, then they are portable and economical, but they lack visibility of the internal environment and cause friction-induced redness and inflammation during insertion and removal
Solution Approach 1:
The patent merges multiple functions into a single integrated device: illumination (lamp), visualization (camera and display), and anti-inflammatory treatment (atomizing head with medicine compartment). This combination maintains the portability and simplicity of traditional light rods while adding capabilities to reduce airway inflammation and improve visualization.
Solution Approach 2:
The patent applies preliminary action by delivering anti-inflammatory medication through the atomizing head before and during the intubation procedure. This pre-treatment reduces airway inflammation and friction effects before the light rod is fully inserted, minimizing patient discomfort and infection risk.
3Productivity
If multisource end-expiratory CO2 monitoring is used to determine tracheal intubation position, then it can be easily adjusted and improve efficiency, but it has great dependence on device accuracy and is vulnerable to sensor deviation, failure, or data analysis disturbances
Solution Approach 1:
The patent incorporates real-time visual feedback through the camera and display screen, allowing operators to directly observe CO2 visualization and confirm proper tracheal intubation position. This visual feedback system complements the electronic CO2 monitoring, providing redundant verification that reduces dependence on single-point sensor accuracy.
Solution Approach 2:
The patent provides beforehand cushioning by having the visual observation system ready as a backup verification method. If the CO2 monitoring system fails or provides inaccurate data, the visual feedback from the camera and display serves as a pre-prepared alternative to confirm proper intubation position, ensuring continuous monitoring reliability.

AI summary
The present invention discloses an auxiliary visible light rod for multisource end-expiratory CO2 monitoring. The auxiliary visible light rod comprises a handle, a pump body, a medicine compartment, a rod body and a bracket. The handle is separately connected with the medicine compartment, the pump body and the rod body, and one end of the rod body is connected with a rod head. A lamp and an atomizing head are arranged in the rod head. A circuit tube is connected with the external wall of the rod body, one end of the circuit tube is connected with a display screen, and the other end of the circuit tube is connected with a camera in the rod head. The bracket sleeves the rod body and is fixed to the outer side of an oral cavity or a chin of a patient, and thus the stability of the rod body is improved.
