Design and 3D model of a Vacuum cleaner ventilator

Design 1 and documentation

Hi, I have sketched a new proposed design similar to the initial idea and everything will be documented here(components off the shelf, materials, pricing); https://docs.google.com/document/d/14f_MP1LyWgYdZcQ1h0MMdOZmI_lOCYvG8tjQkkjBEE4/edit?usp=sharing I made the wall blocking the air from the ducts to the gear as mentioned in the picture to adhere to the inspiratory and expiratory breathing cycles with intervals in between. In articles, it mentions that the delaying cycle depends also on the age, size and other criteria, thus it needs to be easily adjustable which will be thought of in the future. The material of bottom base of the ventilator to be strapped around vacuum cleaner is chosen to be SEBS commonly used in AMBU bags; sturdy yet flexible to cope with change in pressure without collapsing. Any thoughts or feedback? I will continue designing in a 3D model using Solidworks if the proposed design is viable. Also, comments can be made in the google docs if you wish to do so.
