Nebulizer Cartridge Lead Angle Reduces Medicament Residue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nebulizer cartridge structures often leave residues of liquid medicament at the bottom, leading to wastage due to their design limitations.
Innovation Solution
The nebulizer features a cartridge structure with a first and second accommodation space, where the connection bottom and side form a lead or fillet angle, creating a larger volume in the first space to efficiently direct liquid medicament to the opening, reducing residues through a nebulization apparatus with a nozzle disc and vibratable member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the opening is positioned near the bottom of the accommodation space, then liquid medicament can be supplied to the opening, but residues of liquid medicament remain at the bottom causing waste
Solution Approach 1:
The accommodation space is divided into two distinct parts: a first accommodation space for storing liquid medicament and a second accommodation space for receiving atomized liquid. This segmentation allows the opening to be positioned at the boundary between the two spaces, enabling complete drainage of liquid medicament from the first space to the opening without residues remaining at the bottom, while maintaining a relatively simple overall cartridge structure.
2Productivity
If the opening is positioned near the bottom of the accommodation space, then liquid medicament can be supplied to the opening, but a portion of liquid medicament is remained to the bottom to waste liquid medicament
Solution Approach 1:
The invention transitions from a conventional single-space vertical arrangement to a two-space configuration where the opening is positioned at the boundary between the first and second accommodation spaces. This dimensional reorganization allows liquid medicament to flow completely from the first space through the opening into the second space for atomization, eliminating bottom residues and improving medicament delivery efficiency while preventing waste.
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
This design effectively minimizes residue waste of liquid medicament, enhancing the efficiency of medicament delivery in nebulizers.
Implementation Method 1
the vibratable member is combined with the nozzle disc and electrically connected to the controlling element
Implementation Method 2
The atomization method is often used to treat respiratory diseases. The method can be achieved by using a nebulizer, and particles sprayed by the nebulizer are droplets that are about 3-5 μm
Implementation Method 3
The connection bottom of the first cartridge accommodation space is connected to the connection side of the second cartridge accommodation space to form an included angle that is preferably a lead angle. The lead angle includes a chamfering angle or a fillet angle

AI summary
A nebulizer and cartridge structure thereof for use in a nebulization apparatus comprises a first cartridge accommodation space and a second cartridge accommodation space. The first cartridge accommodation space includes at least one connection bottom, and the second cartridge accommodation space includes at least one connection side. Moreover, the second cartridge accommodation space is disposed under a lower connection position of the first cartridge accommodation space. The connection bottom is connected to the connection side to form an included angle that can be a lead angle. The lead angle further includes a fillet angle or a chamfering angle. Accordingly, the nebulizer and the cartridge structure can efficiently reduce the residues of liquid medicament.
