Nested Bar Camera for Tracheal Intubation Parallax
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracheal intubation devices with cameras installed on the lateral side of the endotracheal tube slot often experience visual field obstruction due to parallax, leading to inaccurate placement of the endotracheal tube, which can result in failure during intubation, especially in patients with unique anatomical structures.
Innovation Solution
A tracheal intubation device featuring a bar-shaped camera placed inside the endotracheal tube, connected to a display device and a guiding portion, allowing for precise placement by minimizing visual obstruction and enabling the camera to move synchronously with the tube, while being made of a rigid material to guide the tube's direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera is installed on the lateral side of the endotracheal tube slot, then the device structure is simplified, but the visual field is blocked by parallax causing inaccurate tube placement
Solution Approach 1:
The camera is nested inside the endotracheal tube, with the camera lens positioned at the distal end of the tube. This nested configuration eliminates parallax between the camera view and tube position, allowing the visual field to accurately represent the tube's location while maintaining a compact integrated structure.
2Ease of manufacture
If the camera is installed on the lateral side of the endotracheal tube slot, then the device is easier to manufacture, but visual field obstruction occurs leading to intubation failure
Solution Approach 1:
The camera is integrated inside the endotracheal tube structure, eliminating the need for separate lateral mounting mechanisms. This nested design simplifies manufacturing by reducing assembly steps while ensuring the camera and tube move together as a unified system, preventing visual field obstruction and improving intubation reliability.
Solution Approach 2:
The camera and endotracheal tube are merged into a single integrated device, where the camera housing forms part of the tube structure. This combination eliminates relative movement between camera and tube, preventing parallax-induced visual field blockage and ensuring consistent alignment during insertion.
3Ease of operation
If the camera moves independently from the endotracheal tube, then the camera can capture images independently, but the visual field becomes misaligned with the tube position
Solution Approach 1:
The camera is nested within the endotracheal tube structure, sharing the same central axis and movement path. This nested arrangement ensures that the camera and tube move together synchronously, maintaining perfect alignment between the visual field and tube position while allowing the camera to capture images at any point during insertion.

AI summary
A tracheal intubation device for placing an endotracheal tube in the trachea of a patient includes a bar-shaped camera, a handle portion, a guiding portion, and a display device. The bar-shaped camera for capturing images is placed inside the endotracheal tube. The display device is electrically connected to the bar-shaped camera for displaying images captured by the bar-shaped camera. The guiding portion connected to the handle portion has a front end and a rear end. The rear end is connected to the handle portion, and the bar-shaped camera and the endotracheal tube are movably situated in the guiding portion.
