Quick and Easy coronavirus face mask Respirator

It consists of only 2 parts, the 3D printed bits and some kind of filter. It's designed to be used with normal facial tissues, the kind you can buy in many shops to blow your nose on. The finer the better. It's comfortable to wear because the only thing against your face is the tissue.

It is absolutely not meant to replace a proper N95 medical mask. However, it will offer some protection where no other option is available. It's very simple and just holds the tissue snugly in place around your nose and mouth.

It is very economical in terms of material usage and takes just over an hour to print with 0.3 mm layers in PLA.

I have only just finished this and it hasn't been tested to see if it fits many people. I need feedback. Especially regarding the size and shape. I will attempt to make modifications and upload them quickly.

There was some research done on the effectiveness of homemade masks. They tested a range of household materials (surprisingly not tissues though). See link below. They all show a marked improvement over not using anything at all. If anyone can find any research on how effective tissues are, please make me aware of it so I can put in a link to it. Tissues looks extremely fine to me so I can't see why they wouldn't work.

New ventilator mask protects entire face from coronavirus

https://www.israel21c.org/new-ventilator-mask-protects-entire-face-from-coronavirus/ Many people are wearing facemasks to avoid breathing airborne coronavirus particles, and to keep from touching their noses and mouths. However, even N95 masks can’t fully block tiny virus particles and can’t kill the virus (two masks under development in Israel aim to do that). Any blocked viral particles stay on the mask’s surface and pose a hazard when handled and thrown away. Furthermore, facemasks don’t cover eyes. Although the nose is the main route for coronavirus into the lungs, some researchers believe the eye’s conjunctiva is another possible point of entry. That’s why Israeli physician and serial medical-device inventor Dr. Noam Gavriely worked quickly to develop what he calls the ViriMASK Protective Oculo-Respirator . ViriMASK is strapped around the head, covering the eyes with a see-through visor and the nose and mouth with a filtering mechanism....

Ventilaid breathing device Mk III

VentilAid is a very simple, yet effective device for non-invasive ventilation. It is especially projected to help patients suffering from COVID-19. VentilAid helps breathing, prevents alveoli from collapsing and monitors patients health. Major features Compactness and mobility Universal power supply Automatic function in CPAP and BiPAP modes FiO2 do 70%, Up to 70% FiO2 Pressure up to 15 cm H2O (wi th a greater technical capablity of up to 30cm H2O) The device adapts to the breathing rhythm of the patient https://www.ventilaid.org/ventilaid-breathing-device-mk-iii/

Mask Strap Efficiency This simple but useful tool is designed to make face masks less painful to wear for medical workers treating coronavirus patients. The part is made by printing a set, and then connecting with any filament which will also set its width. In this way, the filament which is needed for a single print is reduced and 18 sets on a 250x250mm print bed are allowed. Small protrusions on both sides of the plastic buckle hold the mask strap and the mask strap does not exert painful pressure on the ears. References: Michael B. ( 2020 ). Prusa Printers.
