Camera-Guided Nasal Fluid Delivery for Olfactory-Zone Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nasal dispensing devices often fail to effectively target the olfactory zone and ethmoid sinuses due to variable device orientation, which is influenced by patient morphology and position, leading to inefficient delivery of fluid products.
Innovation Solution
A nasal dispensing device equipped with a camera for spatial positioning, a positioning indicator, and automatic actuation means to ensure optimal orientation and deposition, guided by visual, audible, and tactile feedback, ensuring precise angular positioning and automatic dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual insertion method is used, then device simplicity is maintained, but positioning precision deteriorates due to variable orientation
Solution Approach 1:
The patent implements a camera-based feedback system that captures images of anatomical landmarks (nostril, nasal septum, turbinates) to calculate device orientation angles (α, β, γ) and provides real-time feedback to guide the user in adjusting device position and orientation to achieve optimal targeting of the olfactory zone
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated optical measurement system using a camera to detect anatomical landmarks and calculate spatial orientation, substituting subjective user judgment with objective image-based measurement
2Measurement precision
If automated positioning system is added, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single handheld device: fluid product reservoir, dispensing mechanism, camera system for spatial positioning, and user interface for guidance, allowing one device to perform both medical treatment and positioning guidance functions
Solution Approach 2:
The patent introduces a processing system that acts as an intermediary between the camera data and the user, automatically calculating orientation angles, comparing them to target values, and generating guidance signals to simplify the user's task
3Reliability
If orientation control is implemented, then deposition effectiveness is improved, but ease of operation deteriorates due to alignment requirements
Solution Approach 1:
The system continuously monitors device orientation through camera-based detection and provides real-time feedback via visual or auditory signals to guide users in adjusting their insertion angle, making the complex task of precise orientation more accessible
Solution Approach 2:
The system performs preliminary calculation of the optimal insertion angles based on individual anatomical landmarks detected by the camera, allowing the device to adapt to each user's unique nasal anatomy before dispensing the fluid product

AI summary
A device for nasal delivery of fluid product, having a reservoir containing a fluid, a delivery member, and a delivery head on the delivery member, and the delivery head provided with a delivery opening. The nasal device has a camera for determining the spatial positioning of the nasal device inside a nostril, the camera determining the vertical tilt angle and the lateral tilt angle between the longitudinal axis of the nasal device and an axis of the face identified by a plurality of reference points, the orientation of the axis with respect to the nostril identical to whatever the position of the user, a positioning indicator for guiding the user towards an optimal orientation of the nasal device inside the nostril, and an electronic module and automatic actuation mechanism for automatically actuating the nasal device when the camera determines that the nasal device is disposed in an optimal position.
