Nebulizer Sealed Container Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulizers require users to open and close the device, insert and replace containers, which can lead to incorrect handling, soiling, and operational reliability issues.
Innovation Solution
A nebulizer design with a pre-installed, non-replaceable sealed container that is opened internally before first use, ensuring easier operation and improved reliability by preventing incorrect insertion and unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the container is made replaceable and the nebulizer is opened for insertion, then the device is more versatile and adaptable, but the ease of operation deteriorates and reliability worsens due to incorrect handling and soiling
Solution Approach 1:
The container is pre-installed in the nebulizer in a sealed state before delivery. The sealing element prevents opening until the nebulizer is activated by the user, at which point the conveying element automatically opens the container. This preliminary installation eliminates the need for users to manually insert containers, simplifying operation while maintaining the ability to replace containers at the pharmacy level.
2Reliability
If the container is pre-installed and sealed in the delivered state, then the ease of operation improves and reliability increases, but the device complexity increases
Solution Approach 1:
The sealing element and conveying element are integrated into a unified system where the conveying element serves dual functions: conveying the fluid and simultaneously opening the container by displacing the sealing element. This merging reduces the number of separate components needed, thereby reducing device complexity while maintaining reliability through the pre-installed sealed container configuration.
3Reliability
If the container is made non-replaceable, then the reliability improves by preventing unauthorized use, but the adaptability deteriorates
Solution Approach 1:
The container is pre-installed in a sealed state and can only be opened upon activation of the nebulizer. After opening, the container becomes non-replaceable by the user, preventing unauthorized reuse. However, the nebulizer can still be returned to the pharmacy for professional refilling, maintaining adaptability at the pharmacy level while ensuring reliability during patient use.
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 design simplifies operation, enhances safety by preventing misuse, and ensures consistent use until the container is empty, thereby improving user experience and device reliability.
Implementation Method 1
a spring pressure of 5 to 200 MPa, preferably 10 to 100 MPa on the fluid
Implementation Method 2
it is pierced through its base by a piercing element in the lower housing part to allow air in or out

AI summary
A nebulizer for a fluid, particularly for medical aerosol treatment is proposed. To allow easier operation and confer improved operational reliability a sealed container holding the fluid is already arranged in the nebulizer when it is supplied and the nebulizer is constructed so that the container is opened inside the nebulizer before or during the first use of the nebulizer. For this purpose, a transportation lock is provided for the sealed container which, in the delivery state, is in engagement with the sealed container in a manner preventing the sealed container from moving axially in the nebulizer.
