Hi. In my previous video, we took a look at how Medtronic's had supposedly opened up the designs for their a ventilator and how well it wasn't really of much value to most people. Probably the only major benefit to it was that they actually opened their specifications which is not really of any value for any like short-term project. we need a ventilator Now it's not probably not going to help you a huge amount, but it could be a value to those who want to do like a ventilator project like long term.

take it seriously, spend the many years required to engineer it properly and get an FDA approved, blah blah blah or all the rest of it so you know, still a credit to Medtronic's for that. But of course they didn't really release anything else likes PDF schematics and that was about all she wrote. but they did. There was some vague promise to actually release the source code for this, now that's all they mentioned at the time.

Now as it turns out, we'll go through an update for this and then we'll talk about other open source ventilator projects because there's this awesome list of our and the status for other open source ventilator projects. So anyway, as it turns out, they have updated the webpage, the Open Files A webpage here. This wasn't here before. More documents and source code files pertaining to the PBE 560 ventilator system will be available soon that wasn't there when I put mine.

So I can't help but think that they have seen my video and other criticism around about their release of these supposed you know these specifications and and things and they've acted to release more stuff. And to their credit they have actually released more things. But unfortunately that page link that I had that thank-you page where you can download the files directly. It looks like they've shut that off.

So you do actually have to register here and you have to read and agree with the permissive license. Now let's talk about this for a minute because if you're thinking about starting an open-source ventilator project or some other, even if it's a commercial ventilator project and you use this as a baseline, as generous as it is of Medtronic's to actually release their specifications and as we'll see, I believe they're released the CAD files, the Kicad files, and and other like the Molt you know 3d mechanical stuff and I think Bill of Materials As somebody said, I haven't looked at it yet, but apparently they have released a ton of stuff to potentially make an equivalent compatible product to their PB 560 a ventilator. So but to get it, you have to agree to this permissive license. So I would be very wary of studying any open-source project or any commercial project based on this unless you have really top quality lawyers.

Vet this permissive license agreement because if you go in here and the major one right here modified permissive license limited term this permissive license is effective from the time you download the design materials and software until the earlier of one. The final day of the who's Phe IC is in effect. I Assume that means like it's a pent. they've declared the pandemic.

Once they stop declaring of the pandemic, then this permissive license ends ie. you're licensed to this material ends or be October 1st, 2024. So it's the earlier of those two things. So even if it's still a pandemic in 2024, it will end.

You potentially won't be able to sell or even build your ventilators based on this design after it's not declare the pandemic or the term ends Now to be fair, Medtronic's may not enforce that, but it seems like this permissive license is there. So if you download this information and they even and their lawyers even think that you've copied any aspect of their design or specifications or whatever it is, they can potentially sue you. Okay, you're leaving yourself wide open. So yeah, while this is a generous move on the part of Medtronic's I'd be very careful about this, so if there's any yeah lawyers out there, please let us know how potentially you know troublesome this could be and says right here you have the license.

During these time periods that we've talked about to actually make and sell a ventilator, ever partially or wholly based on the information that they've provided in response to this pandemic crisis. So once it's not a pandemic in Moore, it's like maybe you should stop selling it or stop producing and what effect that has on open source? How about like you can't just take their information and then open source it and put an A whatever open source hardware license on it you want and then think that that then it becomes magically free. It doesn't Medtronic's still have the right to this information. You've agreed to use this license.

so technically I don't even think that would be applicable under the Open Source hardware license. So please correct me if I'm wrong. It's been a while since I've looked at the ins and outs of the open Source, various hope and source hardware licenses and even the like official certified one. I Don't think it would actually be possible to make a ventilator and call it open source hardware if you got the information from this Medtronic's documents and then if you use the software for anything else, you're screwed.

But they can't revoke it until the end of that, until the pandemic finishes or the end of that date. And they're saying here your sale or distribution of your ventilators condition upon your attaining all required regulatory approvals in each country. So if you're looking as many of these projects are that we'll see in a minute looking at doing like a makeshift open source ones that are just all out there. Like technically, this license does not give you the ability to do that.

The distribution of your vendor if you actually sell the hardware doesn't stop you releasing the information to build it. I would presume. correct me if I'm wrong lawyers. but if you want to distribute it or sell it, even if you want to give it away for free, that's distribution that's not an It.

If you don't get regulatory approval, it's not covered. So I Don't see how technically in theory any information Medtronic's has released is conducive to producing ventilators. Ah, that we need right now. So if all these teams working on these quick, you know, a couple of months development cycles to try and get the ventilators out there so that these makeshift ventilator projects out there you can't get FDA approval that quickly.

Or you maybe could if you're you know, who is it Mercedes Benz and the other huge companies that are working on ventilators. Maybe you can get them to approve it. But yeah, good luck. If you're little, you know a hackerspace project or something like that produces something useful technically not caught on this license, you can't use it.

and also you must provide a link to this license in your open Source ventilator design and things like that. Of course that's just a regular part of it, but yeah, you have to link to this so that people using your project know that there's an expiry date on this license. After that, the lawyers can come and suck your blood and you have to provide this message as well. Jeez, it's like okay, they're really going to town telling you what you can and can't do with this information that they've generously provided.

Now call me cynical, but my spidey sense is telling me that they don't quite have the community and industries like best Interests at heart here. I Think they have their bottom line, the corporate interests at heart here. but once again, it's a good move to release this. I'm just saying be very careful about this license.

And now, whilst I'm not a cynic I did, but there could be people out there who might think that the release of this information is kind of ma'am could potentially be related to some bad press they got about recently in the New York Times about how the U.s. tried to build a new fleet of ventilators, but the mission failed and if we search for Medtronic down here, we go down here. So I'll link this article down below. you can read it for yourself.

I won't get into all the details I might get a couple of details wrong here, but basically like I think almost a decade ago or something the US government put out this contract to produce an emergency stock of ventilators because they knew a lot of people knew that this thing was. this pandemic was inevitable, right? and we might have. Having a strategic stockpile of ventilators was a good thing. So the government was actually forward-thinking in that aspect and apparently are the first contract are fell through or something.

but then the but then they started over and awarded a new contract for thirty million dollars to Philips But in 2015 Kovaydin who got the contract was sold for fifty billion dollars to Med Tronic S--. and and the CFO is saying he did not know why the contract had fallen apart I Am not aware of this issue and they're saying like people involved had no recollection of the project and contract and things like that. Anyway, Medtronic's to be fair, are claiming that it wouldn't have met specifications anyway, but apparently a contract was awarded and Medtronic's took that company over and they haven't produced any ventilators. So anyway like yeah, I don't know the details of that LinkedIn down below.

Now our download these new files in a minute and take a look. but I just wanted to point out this: thank you I forget who I sent it to me I was someone who's working on a open source ventilator sent this. It's a public Google document analysis of the various open source Pandemic Ventilator projects and I've heard from people on Twitter that this is not a complete list. Look at them all right.

There is a I don't know how many is that? That is a lot, right? That is a lot of projects here and they've ranked to them so well done to Robert L Reed, Kushina, Patel and 1e viscera Perez sorry I'm butchering that. Um, who compiled this list oops I Assume it's ongoing. Absolutely fantastic that date last evaluated. There you go and they've given like ratings to each project of what progress they're at and things like that, how open they are, the build ability of the community support, functional testing that they've done reliability testing, whether or not it's actually suitable to this current process I Whether or not it's clinician friendly and an average score, but it looks like like the best one up here like they've ranked it here.

EMBO Vent It seems to be the best one, but there's another low-cost open source one Vini Aid Anyway, I'll link this in down below and they've put notes over here. Claims will be made open source. Extremely impressive documentation showing privately and things like that, but there is no shortage of these projects. So if you've got the skills to work on these projects, in particular, people who have skills in ventilator design our CPAP which is a similar so that you know it's similar sort of technology I Guess the you know CPAP masks and things like that and other medical type devices I mean guys like me with like hardware and firmware skills and stuff or like dime a dozen but know if you want to contribute if you have really like real specific skills in ventilated design and stuff like that.

So yeah, I'm sure have a look through these projects and find one that suits your fancy and by all means contact them and and contribute to this. So hats off to that list. Absolutely fantastic! So here it is: I Submitted the information I Confirmed that I abide by their license agreement and they whether or not this is it, be sure to check back soon. They're going to say there's going to be more but looks, this is the original one that we looked at and this is new one 287 Meg Ventilator system includes manufacturing fixtures, our printed circuit board drawings including motor bombs.

Okay, so that's the bombs for the PCB But really, as I said, this is at like a ninety percent mechanical project. So if you don't have the bomb for all the motors and the filters and the other widgets, valves and things that are used inside all the pumps and all the mechanisms and stuff like that I it's once again it's not a huge use really. 3d CAD files maybe for the case. mechanical part drawings Okay, well we'll see what they've got and the permissive license of course.

Alright, let's have a look at what we've got: Electronics: PCB Assemblies Power Management Let's go for the CPU PCB assembly. At least somebody said they were Kicad. Oh, this is nice. We've got the oxygen valve hardware specification relief valve, exhalation control valve or that could be nice.

Okay, we didn't have that before oxygen valve. this looks good. Oh wait, it's pretty old. but uh, there's the specifications for the oxygen powers.

Okay, this is really good. Once again, subject to the license. so yeah, but how do you? Okay, it's the specification but like can you buy it like I assume it's a custom thing. Is it no no Switzerland no it looks like a false are false are in Switzerland I assume that's a company that makes these.

There you go is is that the part number? if that's the case. Beauty If you can get like all the sensors and stuff off the shelf, that's absolutely fantastic. Well done. Medtronic's so there you go.

But once again, if you download this information, you agree to that license theory of operation for the exhalation valve, de-energize position technology valve I'd yet like I don't know I'm not a mechanical engineer I don't know looking at ear. really hope he's gonna budge it up if I try and do anything but that the life of the valve I Once again, Fluid Automation Systems There you go that's looks like who they. that's who they buy it from so it looks like off-the-shelf stuff. Beauty PCB Specifications: Well I see is alternating current I love it.

So yep I've been there done that written written these documents display interface all the time in diagrams. the oxygen sensor I assume if I use flow oxygen, oxygen or something I yes and I specs. There is their full fabrication drawing for the PCB nice. And here are all the files in the PCB non plated through their Gerber's our board.

There we go. Okay, that might looks like dot pro that's a key CAD project file Maybe let me try and load it now I'm trying to unload it. unfortunately it gives me I'd like it. gave me a file Aramis whenever So maybe these aren't Kicad files.

So I opened the dot profile and aha see our 5,000 board Designer Version 4:13 that is Su Caen So that's the package that they used I don't have that. Sorry. So I'm unable to load them up. but I assume that these it looks like the whole shebang.

It's got the board file and everything. So yeah, it looks like they have released the CAD files for the PCB no workers manufacturing fixtures, plastic tube cutter look. that's their tool. That's them.

These are their manufacturing tools. This is actually really quite good. Like hats off once again. Stopcock.

What a good stopcock. There you go. Do you monetized like battery plate assembly or something like that? I don't know. I like it.

Yeah, it's all there. It looks like they're releasing all of the info for their entire manufacturing thing of this. Okay, these are the 3d CAD models is solid part. I seen that SolidWorks sorry I don't have SolidWorks license but look at them all right? That is all their stuff.

They have genuinely released the whole lot. I Know now with like it seems like off-the-shelf sensors and everything and valves and all that sort of stuff and all the PCB files. it looks like somebody could actually manufacture this 560 ventilator so that's fantastic. Um, so yeah, really.

once again I'll say it multiple times. Hats off to Med Trikes, but beware of the license and no doubt their hearts in the right place. right? We need more ventilators due to this crisis here it is. But really, how long is it going to take somebody to take all this information and with no employees from the company like everyone has to learn all this stuff and then actually produce the finished PB 560 ventilator? It would be easier just if they you know just kept churning out the 560 regulator's themselves.

I mean you know it's great, but the fact that that license is so restrictive that then prevents other potentially prevents other people from actually you know, coming out with products that can be potentially used beyond this pandemic because there's like it could and in six months they could stop that pandemic over licensed. Boom is is revoked, technically revoked for this thing and you you know you've completely come a gutter and all that effort you've put into mmm, you know, manufacturing that new ventilator. Just Boom can stop just like that, otherwise they could see you out of existence. potentially.

I for one, welcome our new Medtronic's overlords. It's going to the mechanical part. Wow, that's a lot of subdirectories. Oh that.

You've got to go into the part number supporting documentation like what is it? what's what's an IC are like, oh look, yeah, okay, they've got thee as this is a thing that you should do with your projects. Well, you know you have like a project folder that you're working on, right? Include all your PCB files in your source code and everything else you might have in there, include the data sheets as well is a really handy thing to. yeah because file space is cheap these days. It's free, right? So and it's like just copy in the data sheets.

Um, it's just. it's really handy so you've always got them if they just magically vanish like in ten years time or something. I Don't know everything's supposed to be around forever on the interwebs, but you know things can vanish so that's really cool. That's all the mechanical stuff for every single part and presumably every like mechanically type part they've got in this thing.

and I presume the head like 3d models for the case and things like that and everything. So I Okay, I'm gonna call it that. It's all here like it seems to be all here. but they still haven't released the software.

So you know if you race out and build your Medtronic's 560 ventilator right now? Yeah, I Don't wait until they at least release the software before you actually do that. Anyway, there you go. That is fantastic. So anyway, I'm quite impressed that Medtronic's did follow through and have released all of the stuff.

Looks like all the stuff are required, you'd have to go. You'd have to spend days going through everything to make sure that everything's there and and things like that. So to produce this 560 ventilator except the software. but I have no doubts if they've released all this.

I I would actually believe that they're going to release software. Maybe they're busy. Once again, somebody cynically said on Twitter rolls for him or somewhere or YouTube comments that that they're probably busy they can't release the software. Exited busy scrubbing out all the other stuff that they don't want you to see inside the thing.

and I won't speculate as to what that is. You can speculate down in the comments down below. But anyway, yes, hats off to Medtronic's for doing this. My only concern with this is this license.

Please lawyers have a look into this. But it seems if you agree to this and that's what you're agreeing to, you agree into the limited term. and I think, please correct me if I'm wrong that they're essentially saying that you cannot open-source this thing. So I Yeah, I don't know.

Anyway, Yep, they at least came through. Hopefully that had something to do with my video actually prodding them to do that. Okay, if you liked the video, please give it a big thumbs up. As always comments in the youtube comments or over on the EEV blog forum it down below.

Catch you next time.
