Ear Medication Dispenser with Tympanic Membrane Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for ear pain, particularly in children due to otitis media, face challenges with messy medication formulations and uncertainty in delivering drugs directly to the tympanic membrane without an otoscope.
Innovation Solution
An ear medication delivery device equipped with a tympanic membrane sensor that automatically or manually initiates medication dispensing upon identifying the membrane, ensuring precise delivery of medications such as anesthetics, analgesics, or antivirals in forms like powders, liquids, or aerosols directly to the ear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ear medication drops are used, then the medication can be administered at home, but the formulation is messy and sticky
Solution Approach 1:
The patent replaces manual dropper administration with an automated dispensing system that uses a pump mechanism to deliver medication through a controlled nozzle, eliminating the messy and sticky issues associated with traditional glass dropper formulations
Solution Approach 2:
The patent changes the physical state and delivery parameters of the medication from liquid drops to a controlled spray or deposited form, allowing precise delivery to the tympanic membrane while avoiding the messiness of traditional formulations
2Device complexity
If traditional ear medication drops are used, then the medication can be administered without special equipment, but one cannot be assured that the medication is getting to the tympanic membrane quickly and in sufficient quantities
Solution Approach 1:
The device performs self-service by automatically detecting the presence of the tympanic membrane using a sensor and triggering medication dispensing only when the membrane is properly identified, ensuring reliable delivery without requiring user judgment or external equipment
Solution Approach 2:
The patent incorporates a sensor that provides feedback about the tympanic membrane's presence and position to the control system, which then adjusts or triggers medication dispensing accordingly, ensuring the medication reaches the correct target with sufficient quantity and speed
3Measurement precision
If an otoscope is used to ensure proper medication delivery, then delivery accuracy is improved, but the device complexity and ease of operation are reduced
Solution Approach 1:
The patent merges the functions of otoscope visualization and medication dispensing into a single integrated device, where the sensor detects the tympanic membrane and the dispensing mechanism delivers medication in one coordinated action, eliminating the need for separate equipment
Solution Approach 2:
The device performs multiple functions including tympanic membrane detection, positioning verification, and medication dispensing within a single unit, making the device universally applicable for both diagnosis guidance and treatment delivery without requiring additional specialized equipment
