Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nasal drip devices have a fixed delivery point, making it difficult to adjust the position of drug delivery in the nasal cavity, which is inconvenient for patients and may not accurately target the nasal olfactory area.
Innovation Solution
A nasal drug delivery device with an adjustable position, featuring an intranasal locking connector, nasal dropper, and syringe pump, allowing the nasal dropper to be movably set and fixed by the intranasal locking connector, enabling precise adjustment of the drip position within the nasal cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed delivery point nasal drip device is used, then the device structure is simple, but the position of drug delivery cannot be adjusted to accurately target the nasal olfactory area
Solution Approach 1:
The intranasal locking connector is divided into multiple components: a locking joint, a hollow body, and a drip fitting. This segmentation allows the nasal dropper to be movably positioned within the hollow body while maintaining overall device simplicity, enabling adjustable delivery positions without significantly increasing device complexity.
Solution Approach 2:
The nasal dropper is designed to be movable within the intranasal locking connector, allowing dynamic adjustment of the delivery position. The locking mechanism enables the dropper to be fixed at different positions along the nasal cavity, providing adaptability for different patient anatomies while maintaining a relatively simple device structure.
2Manufacturing precision
If the nasal dropper is made movable and adjustable, then the delivery position accuracy is improved, but the fixation difficulty increases
Solution Approach 1:
The locking mechanism replaces complex mechanical fixation systems with a simpler elastic deformation-based locking system. The hollow body's elastic material properties enable it to grip the nasal dropper securely when compressed by the locking joint, providing reliable fixation without requiring complex mechanical components or difficult adjustment procedures.
Solution Approach 2:
The hollow body is made of elastic deformation material that changes its physical parameters (shape, volume) in response to compression forces from the locking joint. This parameter change enables the hollow body to transition from a loose fit to a secure grip on the nasal dropper, facilitating easy adjustment while ensuring reliable fixation at the desired position.
3Reliability
If the hollow body is made of elastic deformation material, then the fixation reliability is improved, but the manufacturing precision of the locking mechanism increases
Solution Approach 1:
The hollow body's elastic material properties allow it to adapt to slight variations in manufacturing tolerances of the locking joint and drip fitting. The elastic deformation capability compensates for minor dimensional discrepancies, maintaining reliable fixation without requiring extremely precise manufacturing of the locking mechanism components.
Solution Approach 2:
The intranasal locking connector combines the elastic hollow body with the rigid locking joint and drip fitting. This composite structure leverages the flexibility of the elastic material to accommodate manufacturing variations in the rigid components, achieving reliable fixation without demanding ultra-high precision in the manufacturing of individual parts.

Implementation Method 1
the hollow body is a material with elastic deformation, and the nasal dropper passes through the hollow body before locking and fits with or against the inner wall of the hollow body through holes
Implementation Method 2
the nasal dropper passes through the hollow body before locking and fits with or against the inner wall of the hollow body through holes

AI summary
The disclosure provides a nasal drug delivery device with adjustable position comprising: an intranasal locking connector, a nasal dropper, a syringe pump and a syringe. One end of the nasal dropper is movably set through the intranasal locking connector, and the nasal dropper is fixed by the intranasal locking connector, and the other end of the nasal dropper is connected to the output end of the syringe. The syringe is connected to the syringe pump. The split structure of the nasal dropper and the intranasal locking connector are adopted, the nasal dropper is movably set in the intranasal locking connector and fixed by the intranasal locking connector, when the intranasal locking connector is fixed under the user's nasal cavity, by adjusting the length of the nasal dropper in the nasal cavity, the drip position can be adjusted so as to be suitable for different patients.
