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....

Patient Isolation Stretcher Cover PPE to be used while transporting the patient with infectious disease in ambulance or within hospital. The plastic cover can be made with transparent TPU or 16 gauge clear vinyl material and the rods from 1/2 inch ABS pipes. The overall dimensions are kept as 2mx0.6mx0.6m. Plastic zippers to be attached on the sides of the fattened plastic. 8 4" wide glove ports are provided for attaching nitrile gloves on the sides. For air circulation - At the inlet, use 2 HEPA filters 0.3micrometer, 99.99% or more. At the outlet, use HEPA filter along with filters for biological substances. In the Exhaust box, use one way valve and exhaust fan. Usually a 5CFM exhaust fan will provide a ventialtion of 12 times per hour for this volume of containment. A 12 Volt battery is used to power the exhaust unit. A pouch can be attached to the canopy, for holding the battery link: https://grabcad.com/library/patient-isolation-stretcher-cover-1

HealthyPi

The HealthyPi was designed with not just one application in mind, but a variety of them. While it does function as a vital sign monitor for traditional patient monitoring applications, it can also be used for several other applications. You can use it with a Raspberry Pi using a display; use it with a Raspberry Pi with the official touchscreen using our “Complete Kit,” or you can use it standalone by connecting it to any computer’s USB port. The software is compatible across all platforms. Resources: https://github.com/Protocentral/protocentral-healthypi-v3 http://healthypi.protocentral.com
