This is a high profile project.  I'd join the grup to get involved in this.

Sorry, here are attachments.

 

I am tempted to hand this project off in its entirety to the guys at Columbia Gadget Works.  I think they could make a simplified version of this and it wouldn’t hold up PPE projects.  It might be good to do due diligence, though, to make sure we actually can’t just purchase something similar (Johannes)?

Hello Laura –

 

You reached out to the right team.  Kevin Gillis, cc’d, is leading a multi-pronged Hack COVID task force.  He will certainly be in touch soon, we just finished a zoom meeting with colleagues across campus and MU Healthcare to address needs.

Friends,

 

As you all know, those of us at MU Health Care are working hard to be as ready as possible for the inevitable surge of COVID patients. I’m reaching out for some equipment-related help. This is mostly for you brilliant and resourceful engineering folks and for those of you with engineering contacts.

 

One of the treatment techniques that seems to help COVID patients on ventilators is turning them face down in bed. This allows for better lung function. However, without specialized equipment for this, the process of turning requires many staff members (often 5-6) in full body contact with the patient. Given that full body PPE is unobtainable, this is not a safe situation for our staff. We used to have the device pictured in the attachments. For a variety of reasons, this device is no longer available. There are softer, fancier versions out there, but not available.

 

My ask is this: is there anyone willing and able to actually build similar devices? What we want is a contraption that one or two staff members that could slide a patient into and then rotate into a prone position. 

 

Thanks for your help.

 

Laura

Hey Jim,

That gets you most of the way there, Tie them together at the bottom. You have a wheeling base that will rotate and lock in place.
Ideally you then find a bed frame (or cot) that can be attached at the ends.
I'm willing to help with design ideas. I might be able to help beyond that.

But I want to be clear. You moved your goods to market on the roads the rest of us paid for. You hired workers the rest of us paid to educate. You were safe in your factory because of the police forces and the fire forces that the rest of us paid for. You didn't have to worry that marauding bands would come and seize everything at your factory...
 
Now look. You built a factory and it turned into something terrific or a great idea - God bless! Keep a big hunk of it. But part of the underlying social contract is you take a hunk of that and you pay forward for the next kid who comes along."

So running with the idea of minimizing fabrication and using things with established weight ratings
I would suggest using a ladder section, or maybe a scaffolding section for the "bed".  This would limit fabrication (at first glance)
to, two bars to tie the engine stands together, remove the front wheels of each stand, and then a pair of steel rectangular sections at each end of the bed section to bolt it into the engine stand mount arms. These rectangular sections would need to be cut to length, and have holes drilled in them. Possibly you would want to plug the ends. Then a sheet of plywood could be cut to sit inside the ladder rails and another on top, glued together.
Holes could be cut for the patients head, and handles on the sides to lift the whole thing with the patient on it. 
I could draw this up a bit if you're interested.

An idea I had was to see if my employer, Pepco, is able/willing to work on this too. Our steel table frames have been tested up to 3000 pounds in a normal configuration. With some modifications to the frame work I believe it would work well in this situation. I haven't talked with my boss about this yet but I have the rough concept sketched out already and have attached a sketch of the naked frame. Our tables use 12 gauge steel tubing for the legs and 14 gauge tubing for remaining braces. The design I had in mind would use pillow block bearings for ease of turning while under load. The table could be locked in place either with a pin through the A-frame end pieces into the turntable or by locking the turning handle into place (handle not shown). I know Pepco also has been able to source padded vinyl cushions for a product that goes in a doctors office. I can see what the availability and lead time is on that, or alternatively, we can attempt to make our own. What I'm getting hung up on is a safe and robust way to secure the patient while the table is being turned. I admit I don't know enough about the turning procedure to know what is required. Will the patient be immediately moved to another table? Or do they give the patients timed treatments in the same table and turn them over when the treatment is done?

Assuming we can solve the last mile in this design I think it will work well because most of the design is standard Pepco components that are doing pretty much what they were designed to do. 

Anyone have thoughts or suggestions about this? Critiques?

Great idea David.  Pepco, or someone that already is a fabricator, is best placed to work on this.
Did you check out the docs at the very bottom of Jim's e-mail? One is for a commercial version of what they want.
It uses straps for holding the patient. 

Cheers, Dan

I did but I must have been in too big a hurry and didn't see it was straps on a frame holding the patient in in those pictures.
It shouldn't be a problem to make a similar design. I'm wondering if 4 inch nylon load straps would suffice for this purpose? 
I have 20 feet or so, and more can be acquired from heavy duty ratchet straps.
Depending on how long we have for fabrication we can mimic the design in the pdf quite closely.
One of our suppliers bends round tubing for one of our products into a 20 inch diameter ring. They may be able to make a ring that large too.

This is important work.  https://www.google.com/search?q=prone+covid 

That ring is... Only for rotation?  It comes apart.  And they will have to sterilize the whole thing between patients.  I do wish there were videos of the actual product in use. 

Straps? That patient flips over. He is sandwiched between 2 beds.  Big boys like me are going to need support on one side during the flip. 

The face down side is going to need a hole in it.  The caregivers would like a negative pressure room over (under) the patients face to collect the viral effluent. 

I thought of starting with salvage hospital beds. I liked Dans engine mounts, but we need the ability to raise & lower both ends. I LOVE local fabricator, but let's focus on what the hospital already has. 

They have beds with metal frames, lift kits already on them. Take that foam pad off, and we already have castor's & hoist. We need a rigid A-frame at the foot that spreads the weight & straps on their tube frame. The A-frame at the head has to hinge (or slide) because the foot goes up & down so much. 

The rotating bed is going to need U-joints on both ends, and brakes or something to slow & stop rotation. 

Those bed frames come off & expose the structural support below, then the caregivers could get closer to the patient.  We need to see a bed.

I've set up a wiki page for this project to help everyone keep at least basically up to date: http://columbiagadgetworks.org/wiki/index.php/Hack_COVID_Rotation_Bed

I'll do my best to keep it updated and accurate, but I certainly welcome anyone else making changes to the page. Let me know if you are unable to create an account.

Thanks.

Hello again,

Yesterday I took part in a couple online meetings that revealed more information about the healthcare needs for this project. I updated the wiki page with that info: http://columbiagadgetworks.org/wiki/index.php/Hack_COVID_Rotation_Bed#Healthcare_Need

I would like to these meetings and our next steps tonight at 8pm on the hack-covid-voice channel on our discord server: https://discord.gg/SWM8nRM

We are pursuing two different paths to solve this problem but we need to ensure we are meeting the needs of the medical community. To do this, we'd like to continue to refining our ideas in 3d and sketch renderings to find as many problems as we can before we start building and to present to our healthcare contacts to get good feedback on what will work for them.

On Friday, a couple of us will get access to a hospital bed to get measurements and pictures.

Thanks, and I hope to chat with you all tonight. Please let me know if you have any questions.

-Zach
