Balloon-Tip Cerumen Removal with Insertion-Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cerumen removal, including self-administered techniques and medically approved methods, pose risks of injury, discomfort, and complications such as perforation of the tympanic membrane or ear infections due to improper use, especially in individuals with narrow ear canals or excessive cerumen production.
Innovation Solution
A cerumen removal apparatus with a balloon tip connected to a shaft, featuring a controlled inflation mechanism to engage the auditory canal walls, ensuring safe and effective extraction by preventing over-insertion and using a replaceable tip for hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-administered cerumen removal techniques are used, then accessibility and convenience are improved, but the risk of injury and complications increases
Solution Approach 1:
The patent introduces a stop mechanism as an intermediary safety feature that physically prevents the cerumen removal instrument from being inserted too deeply into the ear canal. This stop acts as a mediator between the user's insertion action and the vulnerable tympanic membrane, blocking harmful over-insertion before it can occur while still allowing effective cerumen removal at appropriate depths.
Solution Approach 2:
The stop mechanism provides beforehand cushioning by pre-establishing a safety boundary before any potential harm can occur. The stop is positioned on the instrument shaft to limit insertion depth in advance, cushioning against the risk of tympanic membrane perforation that would otherwise occur during self-administered cerumen removal.
2Productivity
If deeper insertion is performed to reach impacted cerumen, then extraction effectiveness is improved, but the risk of tympanic membrane perforation increases
Solution Approach 1:
The stop mechanism serves as an intermediary that reconciles the conflict between achieving deep enough insertion for effective cerumen extraction and preventing over-insertion that could cause perforation. It allows the instrument to reach the necessary depth to access impacted cerumen while automatically preventing further insertion that would endanger the tympanic membrane.
3Device complexity
If repeated use of the same tip is allowed, then device simplicity is improved, but the risk of infection increases
Solution Approach 1:
The patent employs disposable tips as cheap, single-use components that eliminate infection risk associated with repeated use. Each tip is designed to be discarded after one use, preventing cross-contamination and infection while maintaining overall device simplicity through a modular design where only the tip is replaced, not the entire instrument.
Solution Approach 2:
The cerumen removal device is segmented into a reusable body and a disposable tip. This segmentation allows the complex sterile component (tip) to be easily replaced while the simpler non-sterile body (handle, stop mechanism) can be reused, balancing device simplicity with infection prevention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides a safe, controlled, and effective approach to cerumen removal, minimizing discomfort and reducing the risk of injury while ensuring user safety and convenience.
Implementation Method 1
The balloon's controlled inflation facilitates cerumen extraction by bypassing the cerumen during insertion, then after inflation engaging the auditory canal walls to push the cerumen out of the ear canal as the balloon is extracted.

AI summary
An apparatus, system, and method for removing cerumen from a subject's ear is disclosed. The apparatus includes a tip having a shaft with a passage extending from a proximal end and a balloon positioned away from the proximal end. The balloon is coupled to the shaft in fluid communication with the passage. The apparatus further includes a body comprising a head configured to couple to the shaft and a handle attached to the head for user manipulation. An inflator configured to introduce a fluid into the passage to inflate the balloon. The apparatus includes safety features such as an ergonomic ambidextrous handle to enable use with either hand, a stop to prevent eardrum damage, a pressure-regulating mechanism to prevent overinflation, a controlled deflation system, and a soft, flexible balloon material to minimize discomfort or injury. These features ensure safe and effective cerumen removal by dislodging earwax without excessive pressure.
