Atomizer Rebound Flushing for Accurate Hygienic Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers suffer from inaccurate metering and potential health hazards due to internal contamination and bacteria growth, leading to insufficient drug dosages and contamination risks.
Innovation Solution
An atomizer design that includes a delivery mechanism with a temporary rebound motion to atomize a pre-determined amount of fluid during the withdrawal of a medication dosage, ensuring accurate dosing and avoiding health risks by rinsing the atomizer before each use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizer is used for the first time or after being left for a certain period, then the fluid passageway may harbor bacteria or be contaminated, but the metering accuracy becomes insufficient and therapeutic effect is reduced
Solution Approach 1:
The patent applies preliminary action by flushing the fluid passageway with a predetermined amount of fluid before delivering the medication dosage. This pre-flush action clears bacteria and contaminants from the passageway, ensuring both hygiene and accurate metering when the atomizer is first used or after being stored.
2Measurement precision
If a pre-determined amount of fluid is atomized during the withdrawal process, then metering accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent merges the flushing function and medication delivery function into a single integrated delivery mechanism. The mechanism performs both the pre-flush of a predetermined amount and the subsequent delivery of the full medication dosage in one continuous operation, avoiding the need for separate flushing and dosing systems.
Solution Approach 2:
The delivery mechanism automatically performs the flushing action without requiring separate user intervention. The mechanism self-regulates to deliver a predetermined amount for flushing, then continues to deliver the remaining medication dosage, making the system self-sufficient for both hygiene and dosing functions.
3Productivity
If the delivery mechanism moves from initial position to tensioning position, then fluid is withdrawn from cartridge, but internal contamination affects the withdrawal accuracy
Solution Approach 1:
The patent applies preliminary action by flushing the fluid passageway with a predetermined amount of fluid before delivering the medication dosage. This pre-flush action clears bacteria and contaminants from the passageway, ensuring both hygiene and accurate metering when the atomizer is first used or after being stored.
Applied Scientific Principles

AI summary
Disclosed are an atomizer for a fluid and a method for conveying and atomizing a fluid. The atomizer includes: a cartridge for accommodating multiple doses of the fluid; a delivery mechanism movable from an initial position to a tensioning position for withdrawal of a medication dosage of the fluid from the cartridge when the atomizer is tensioned, and movable from the tensioning position to the initial position for atomization of the medication dosage of the fluid when the atomizer is activated; a pre-determined amount of the fluid is atomized by a temporary rebound motion of the delivery mechanism during its movement from the initial position to the tensioning position, and the medication dosage is a single medication dose, and the pre-determined amount is less than the medication dosage.
