Visual Ear Pick Drug Delivery Head for Precise In-Ear Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual ear picking sticks lack a drug delivery function, and traditional methods for local drug delivery in the ear, such as ear drops or cotton swabs, are imprecise and lead to poor results.
Innovation Solution
A drug delivery part for a visual ear picking stick, comprising a drug bag, a drug bag mounting component, and a drug guide tube, which allows for detachable mounting and precise drug delivery within the field of view of an image acquisition component, ensuring stability and user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional ear drops or cotton swabs are used for drug delivery, then the structure is simple, but the drug delivery precision is poor and results are inadequate
Solution Approach 1:
The patent combines the drug delivery function with the visual ear picking stick by integrating a drug bag, drug guide tube, and drug delivery head into the existing device structure. The drug bag mounting component is detachably connected to the holding section, merging cleaning and drug delivery functions into one integrated tool, thereby improving drug delivery precision without requiring completely separate devices
Solution Approach 2:
The visual ear picking stick is transformed into a multi-functional device that can perform both ear canal cleaning and precise drug delivery. The drug delivery part shares the same handling structure and visual observation system as the cleaning function, allowing one device to serve multiple purposes while maintaining precision through the image acquisition component's guidance
2Manufacturing precision
If a fixed drug delivery system is integrated into the ear picking stick, then the drug delivery precision is improved, but the portability and ease of replacement deteriorates
Solution Approach 1:
The drug delivery system is divided into detachable components: the drug bag, drug guide tube, and drug delivery head can be separated from the holding section. The drug bag mounting component features detachable connections that allow easy assembly and disassembly while maintaining precise positioning during use, thus preserving both precision and portability
Solution Approach 2:
The connection between the drug delivery part and the holding section is designed to be dynamically changeable - detachable when not in use or when replacement is needed, and stable/fixed during actual drug delivery. This dynamic characteristic allows the system to transition between portable/configurable states and precision-operational states
3Ease of operation
If the drug delivery head is positioned outside the field of view, then the device structure is simpler, but the operability and visual control deteriorates
Solution Approach 1:
The drug delivery head is positioned within the three-dimensional field of view of the image acquisition component, utilizing the spatial dimension already established by the visual system. By placing the drug delivery head within the optical path's coverage area, the system enables visual control without adding separate positioning mechanisms, thus improving operability with minimal structural addition

AI summary
A drug delivery part for a visual ear picking stick. The visual ear picking stick includes a shell and a movement arranged in the shell. The movement includes an image acquisition component. The shell includes a holding section and a neck section which are arranged in an axial direction. The image acquisition component is mounted at one end of the neck section facing away from the holding section. The drug delivery part includes a drug bag configured to accommodate drugs and a drug bag mounting component. The drug bag mounting component is detachably connected to the drug bag. The drug bag mounting component is provided with a drug delivery head communicated to the drug bag. The drug delivery head can be located in a range of a field of view of the image acquisition component to cooperate with the image acquisition component.
