Fever Indicating Color Changing Masks With Swappable Contagion Traps

At quarantine borders, test areas etc, snap the 1" plastic air inlet / outlet off, send it in for testing, plus mask itself turns red if the wearer has a fever.

When you are assigned a set of these, they have your information cross referenced on them so putting in a particular module's number will pull up the person's info.

They easily snap off and are put into an airtight container, in fact the container can be made such that you just slip it over the module and squeeze so you don't have to touch it.

Much quicker and more sanitary than doing a swab test.

In addition to this, the mask itself has chemicals in it that cause it to change color to red if the person's temperature is above 100 degrees or so. If somebody has a fever you can see it from hundreds of feet away.

Looking for the swappable contagion module now. [doctorremulac3, Mar 14 2020]



       Cool link, and thank you for that, but they're not better than a mask because they don't contain contagions from a cough. People are wearing a mask anyway, so why not have this added feature?   

       Plus a red mask would be much easier to see from far away than a little sticker.   

       Thank you for the link though, I'll buy some of these for my prototype. This is my weekend project. This might ever save some lives so I'm going to put this on the front burner.   

       Got some time now that my SF Giants season has been put on hold. They told me to hold my tickets, they'll be good for whenever the season starts. (The SF Giants are a baseball team. That's like cricket only with rules.)

       Ok, already been patented for the color changing part. (link) Looking to see if the swappable contagion module has been thought of now.

       Actually nobody would need to administer these, wearers would just walk by a drop off station, put their contagion module in the plastic container or envelope and drop it in the container. Everything else could be done automatically. This would allow one machine to process tens of thousands of tests an hour with little or no exposure to human health workers.

       Not sure if it would be worth it, but you could also separate the in and out valves and test them separately to see if the person is breathing out the contagion or if they've been exposed to it by breathing it in.

       // little or no exposure to human health workers //   

       Very wise; it's important to avoid healthcare workers, particularly doctors. Doctors can make you very ill ...

       I was going to say that the color change, if there's a thermochromic material embedded throughout the mask, would only be around the edges where it's in contact with the skin. But I realized that the middle will be heated by exhaled breath, so it should still work (though it might need a different threshold temperature there). As a bonus, it will be cooled during inhalation, so you can more easily see how fast someone is breathing, if the thermochromic material reacts fast enough.
