Rotatable Nozzle for Targeted Nasal Fluid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nasal spray devices deliver therapeutic fluids in a haphazard manner, resulting in inefficiency and significant wastage, as they do not allow for targeted application to specific surfaces within the nasal cavity.
Innovation Solution
A device featuring a rotatable nozzle with first and second passages, allowing selective alignment with the container outlet to direct fluid flow through specific openings on either side of the nozzle, enabling targeted delivery to specific areas within the nasal cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a spray bottle is used to deliver therapeutic fluids to the nasal cavity, then fluid delivery is achieved, but the delivery is haphazard and indiscriminate resulting in significant wastage
Solution Approach 1:
The nozzle is divided into multiple independent passages (first passage, second passage, third passage) that can be selectively activated. Each passage delivers fluid to a different region of the nasal cavity, allowing segmented targeting rather than indiscriminate spraying. This segmentation enables precise control over which anatomical structures receive therapeutic fluid.
Solution Approach 2:
The nozzle incorporates a rotatable valve member that can dynamically switch between different passages. By rotating the valve member to different angular positions, the system dynamically selects which passage is active, enabling adaptive delivery to different nasal regions based on treatment requirements. This dynamic control eliminates static, one-size-fits-all spraying.
2Reliability
If fluid is delivered in a haphazard manner through a simple spray bottle, then ease of operation is maintained, but therapeutic effectiveness is reduced due to application on inappropriate surfaces
Solution Approach 1:
The nozzle is divided into multiple independent passages (first passage, second passage, third passage) that can be selectively activated. Each passage delivers fluid to a different region of the nasal cavity, allowing segmented targeting rather than indiscriminate spraying. This segmentation enables precise control over which anatomical structures receive therapeutic fluid.
Solution Approach 2:
The nozzle incorporates a rotatable valve member that can dynamically switch between different passages. By rotating the valve member to different angular positions, the system dynamically selects which passage is active, enabling adaptive delivery to different nasal regions based on treatment requirements. This dynamic control eliminates static, one-size-fits-all spraying.
3Adaptability or versatility
If a single passage nozzle is used, then device complexity is minimized, but the ability to deliver fluid to multiple specific locations is lost
Solution Approach 1:
The nozzle is divided into multiple independent passages (first passage, second passage, third passage) that can be selectively activated. Each passage delivers fluid to a different region of the nasal cavity, allowing segmented targeting rather than indiscriminate spraying. This segmentation enables precise control over which anatomical structures receive therapeutic fluid.
Solution Approach 2:
The nozzle incorporates a rotatable valve member that can dynamically switch between different passages. By rotating the valve member to different angular positions, the system dynamically selects which passage is active, enabling adaptive delivery to different nasal regions based on treatment requirements.

AI summary
Devices and methods for delivering fluid from a container to the nasal cavity. The device includes a selector and a nozzle that are connected together and rotatable relative to each other. The device includes a curve to overcome anatomical barriers and one or more openings to provide for effective distribution when delivering the fluid to the nasal cavity. The selector includes an opening that aligns with a corresponding opening in a container that holds the fluid. The nozzle includes a first passage with one or more openings on a first lateral side, and a second passage with one or more openings on an opposing second lateral side. The selector and nozzle can be positioned at a first and second rotational positions to selectively deliver the fluid through the first and second passages to the nasal cavity.
