A group at MIT figured out how to make an emergency ventilator for $100 using a common hospital item — instead of the usual $30,000

How many patients could a single respiratory tech monitor if he/she had to manually look after all those parameters? 2? 5? 10?

I’d think the person monitoring those things manually would go batty in short order.

That’s the easy part!

Great work, MIT !!!!

Rice U. objects to your post.

So what defines the mechanical cycle of this device.

Inhale and exhale most likely.

Glad that someone is actually getting a real, useable college education. Good luck to the MIT team, now and in their future.

They are one of the “solutions” which we have been waiting.

A wooden box like an Apple-1 computer.

Lots of “Maker” kits come with pre-cut thin plywood and interlocking edges like that.

The team is waiting to receive feedback from the US Food and Drug Administration,

They'll all be old men by the time they hear back.

"Here is what to do if you want to get a lift from a Vogon: forget it. They are one of the most unpleasant races in the Galaxy. Not actually evil, but bad-tempered, bureaucratic, officious and callous. They wouldn't even lift a finger to save their own grandmothers from the Ravenous Bugblatter Beast of Traal without orders – signed in triplicate, sent in, sent back, queried, lost, found, subjected to public inquiry, lost again, and finally buried in soft peat for three months and recycled as firelighters."

Love the HHGTTG reference! Quite apropos as well.

Nice looking device. You couldn’t use that as is though. However, I do not believe there would be any way to sanitize the wood body. The body needs to be made of plastic.

[ProtectOurFreedom]

It’s fast, easy and cheap to prototype cases using that notched plywood.

You are right, of course, that it cannot be sanitized or disinfected. Good point.

The developers spent their time on the core product proving it works. Once the innards and their configuration are finalized, they can package it up in a nice 3D printed shell case.

Fits our whole government.

Quite true. The wood case looks kinda cool IMO, even though it's not practical.

Here are a few of the gazillion such laser-cut wood cases and robots...

...a two-week period could require more than one million cycles of the machine.

One cycle per second equals 1,200,000 in a 2 week period.

I’ve made things from old windshield wiper mechanisms.

Speeds adjustable; too.
