Combination Stylet with Medication Atomization for Intubation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endotracheal tube devices require separate instruments for guiding and medication administration during intubation, increasing clinical time and risking patient decompensation due to the lack of a single device capable of performing multiple functions efficiently.
Innovation Solution
A combination stylet and mucosal atomization system integrated into an endotracheal tube, featuring a hollow sleeve with a Luer-style fitting for medication delivery and a bendable guiding stylet for coaxial insertion, allowing for both guiding the tube and administering medication as a fine spray during intubation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate instruments are used for guiding and medication administration during intubation, then each function can be performed with a dedicated device, but clinical time increases and patient decompensation risk increases
Solution Approach 1:
The patent combines the guiding stylet and medication atomization system into a single integrated device. The hollow sleeve serves as both the guiding element and the medication delivery conduit, eliminating the need for separate instruments during intubation procedures.
Solution Approach 2:
The stylet device performs multiple functions simultaneously: it guides the endotracheal tube during intubation, provides structural support, and delivers medications through its hollow sleeve. This multi-functionality reduces the number of devices needed and minimizes clinical time.
2Productivity
If a single device performs multiple functions during intubation, then clinical time is reduced, but device complexity increases
Solution Approach 1:
The guiding stylet and medication delivery system are merged into a single device. The hollow sleeve of the stylet serves dual purposes as both a structural guide and a medication conduit, simplifying the overall system while maintaining multiple functions.
Solution Approach 2:
The medication atomization components are nested within the hollow sleeve of the guiding stylet. The Luer-style fitting and atomization mechanism are integrated inside the stylet's hollow structure, allowing compact multi-functionality without proportionally increasing external device size.
3Adaptability or versatility
If existing laryngotracheal cannulation devices are used, then medication can be administered, but they cannot be placed inside the endotracheal tube alongside a guiding stylet
Solution Approach 1:
The device merges the guiding stylet and medication delivery cannula into a single integrated structure. The hollow sleeve of the stylet provides the internal pathway for medication delivery, allowing the device to be placed inside the endotracheal tube alongside the guiding stylet without requiring separate instruments.

Function Achieved in This Case
Facilitates efficient anesthetization of the vocal cords, larynx, and trachea, reducing the need for multiple devices and minimizing clinical time, while ensuring safe and effective medication delivery during intubation procedures.
Implementation Method 1
a channel is defined between the guiding stylet and the sleeve, and liquid introduced under pressure through the fitting is communicated by the channel to the nozzle
Implementation Method 2
a nozzle at the second end for generating a fine spray of a liquid

AI summary
A combination stylet device for use in guiding an endotracheal tube during an intubation procedure includes an elongated hollow sleeve having a fitting at one end configured for mating with a syringe and a nozzle at the second end for generating a fine spray of a liquid forward from the second end. An elongated bendable guiding stylet is disposed coaxially within the sleeve to define a channel through which pressurized liquid is conducted from the fitting to the nozzle. The sleeve is inserted into the endotracheal tube during intubation to guide the insertion and to allow for administration a medication from the end of the endotracheal tube.
