Disposable Cellulose Aerosol Mask Assembly for Hygienic Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inhalation accessories for aerosol therapy require thorough washing and sterilization after use, particularly in medical facilities, which is cumbersome and poses risks of virus and bacteria transmission.
Innovation Solution
Inhalation accessories made from cellulose-based materials like paper or cardboard, designed with locking mechanisms for easy assembly and disassembly, allowing for disposable use and eliminating the need for cleaning and sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If reusable inhalation accessories (mask, mouthpiece) are used, then the device can be used multiple times, but thorough washing and sterilization are required after each use which is cumbersome and poses risks of bacterial and viral transmission
Solution Approach 1:
The patent applies the disposable principle by providing mask and mouthpiece made of cellulose-based material that are intended for single use only. After use, these components are discarded rather than cleaned and sterilized, eliminating the cumbersome cleaning process and infection transmission risks while maintaining reusability through continuous supply of new disposable units
2Ease of operation
If disposable mask or mouthpiece made from cellulose-based material is used, then washing and sterilization are eliminated, but the material must maintain sufficient rigidity and structural integrity during use
Solution Approach 1:
The patent applies composite materials by using cellulose-based material (paper or cardboard) with specific properties - it provides sufficient rigidity and structural integrity for single-use applications while being lightweight and easy to manufacture. The material is engineered to maintain its shape and function during the brief usage period before disposal
3Stability of the object's composition
If traditional reusable mask or mouthpiece is used, then structural integrity can be maintained over multiple uses, but the device complexity increases due to multiple components requiring assembly and disassembly
Solution Approach 1:
The patent applies merging by integrating the mask or mouthpiece directly with the nebulization ampoule as a single unit. The cellulose-based mask/mouthpiece is designed to be applied directly to the ampoule outlet without separate connection components, reducing the number of parts and simplifying both assembly and disposal processes

AI summary
The present invention relates to an accessory for aerosol therapy, in particular a mask or a mouthpiece, and a method for manufacturing said accessory. The manufacturing method comprises the steps of: - providing a cellulose-based sheet; - cutting out, from said sheet, a shape (12; 112) corresponding to the flat development of the mask or mouthpiece, said shape (12; 112) comprising locking means (14; 114); - forming the mask (10) or mouthpiece (100) by bringing two opposite sides (16a, 16b; 116a; 116b) of the shape together, said locking means being suitable for locking the mask or mouthpiece in the formed usage configuration.
