Transtracheal Ventilation Device with Pivotable Connecting Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transtracheal ventilation devices are limited in their ability to accommodate patients with abnormal anatomy, swelling, or bleeding, as they are not adaptable and can cause damage or discomfort due to kinking or slipping during patient movement.
Innovation Solution
A device with a base plate and a pivotable, flexible connecting part made from elastically bendable material, allowing the lumen to be inserted with a large enough bend radius and adaptable angle to accommodate abnormal anatomical conditions, preventing damage and discomfort by ensuring a secure fit and movement compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid connecting part is used to maintain stable positioning, then the device structure is simple and reliable, but the device cannot adapt to abnormal anatomy and causes pain or injury during patient movement
Solution Approach 1:
The connecting part is designed to be pivotable relative to the base plate, allowing dynamic adjustment of the lumen insertion angle to accommodate abnormal anatomical conditions. The pivotable fastening mechanism enables the device to adapt to different patient anatomies while maintaining a relatively simple overall structure.
Solution Approach 2:
The device allows change in the geometric parameters of the connecting part, specifically the angle of insertion of the lumen, by enabling pivoting movement. This parameter change allows adaptation to abnormal anatomy without fundamentally redesigning the entire device structure.
2Reliability
If the lumen is inserted tightly through the base plate opening to prevent displacement, then the lumen position is stable, but the lumen is damaged or kinked in the area of the device
Solution Approach 1:
The device separates the functions of positioning and protection by creating a dedicated fastening mechanism that is pivotable and positioned at a distance from the base plate opening. This segmentation allows the lumen to be securely held without being constrained or kinked at the opening itself.
Solution Approach 2:
The pivotable fastening acts as an intermediary between the base plate and the lumen, providing secure attachment while allowing movement and preventing direct contact between the rigid base plate opening and the flexible lumen that could cause damage.
3Adaptability or versatility
If the connecting part is made flexible to accommodate movement, then the device can compensate for patient movement, but the connecting part may slip or cause discomfort
Solution Approach 1:
The pivotable fastening mechanism provides controlled flexibility, allowing the connecting part to move and compensate for patient movement while maintaining stable positioning through the pivotable attachment to the base plate.
Solution Approach 2:
The device allows controlled change in the angle and position of the connecting part through pivoting, enabling movement compensation while maintaining stability through the pivotable fastening mechanism that prevents excessive displacement.

AI summary
Disclosed is a transtracheal ventilation device including at least one base plate with an opening and comprising a tubular connecting part with a channel and a central axis. The base plate and the connecting part are connected to each other such that a lumen, when inserted into the device, extends into the channel through the opening along the central axis to a fixing element (a fastening). The fixing element can be pivoted relative to the central axis. The fixing element is arranged at a distance of at least 5 millimeters along the central axis from a base plate face which faces away from the fixing element, and the opening has an inner diameter which is at least 20% larger than an outer diameter of the lumen at least on a first plane perpendicular to the central axis.
