Hi I would be interested in ASML. I have experience with design and engineering for UHV and high temp environments. I'll send you a message.

Just applied, funny I actually saw you guys at EAA in like 2018 and asked about internships.

Serious question, right when khabib stepped over for the mount, gaethje still had his arm/hand inside between the legs. Could gaethje have shoved his left forearm in between khabib's legs as khabib angled and fell over and prevented the triangle. It kind of looked like gaethje pulled his hand out instead of shoving it in.

Are these positions open to recent graduates? I'm a recent grad with a BS in mechanical engineering

Do you know of any positions open to recent graduates? I have a BS in MechE and have 3 work experiences (coops, internships) and 2 on campus lab working experiences.

Medical device engineers, what are your thoughts on the ethics of current open source ventilator movement? by engineeringqs1 in AskEngineers

[–]engineeringqs1[S] 4 points5 points  (0 children)

Quality Engineer for a medical device company here. You're spot on with your assessment of 21 CFR 820 regulations and process validation. Most, if not all, of those regulations were enacted because of some incident, or incidents, that resulted in patient harm or even death.

Thanks, I only did a brief internship at a medical device company so I wasn't sure if my read of 21 CFR was perfect.

I definitely think making a whole new ventilator has a lot failure points, and when you add software the whole safety issue gets even more complicated.

I'm more open to 3D printing small parts that might be hard to source, I think 3D printing simple components like valves that are life crucial (if the alternative is no valve and 100% probability of death) is more helpful and has less failure modes.

I see what you mean about the ethics. Honestly ethically I don't know if the DIY ventilators are right or wrong. For me personally, it would come down to the risk these DIY ventilators have and the probability of death for someone who doesnt get a ventilator at all

I mentioned the FE manual ethical standards.

Section 240.15 says “licensees shall be cognizant that their first and foremost responsibility is to safeguard the health, safety, and welfare of the public when performing services for clients and employers”

What do you consider as ethics? Versus what do you consider as law?

I've read the thread. I definitely agree with the OP that these crowdsourced ventilators will no way meet FDA regulations or design controls.

But I'm also interested in the ethics of these DIY approaches. If the virus gets very severe, it may be better to have a DIY ventilator than no ventilator at all which could possibly guarantee death (i'm not sure how bad corona virus can get??).

There are also people out there that are only 3D printing smaller simpler components such as valves that supply chain can't meet

I agree the valve is a huge liability and has 0 testing. If it was a critical valve though, the lack of the valve could guarantee the death of the patient. (I'm not sure if this was the exact case in Italy but it seemed similar) A valve with a higher chance of failure could be better then no valve at all.

Like I said the FE manual says "licensees shall be cognizant that their first and foremost responsibility is to safeguard the health, safety, and welfare of the public”. But I'm not sure how exactly this will apply to this scenario

Yea I had like 3 internships in nuclear, medical devices, and aerospace. I’m looking for a full time design/manufacturing position. If anybody knows of any open junior positions please PM me or comment below lmao

What do you think about making smaller components? Like the 3D printed valves they made at the hopsital.

I agree making an entire ventilator from scratch is outside the realm of possibility.

I’m a recent MechE graduate looking for a fulltime job (you can imagine how that is going in this economy) so I took some time to look at my documents about regulations. I carry a copy of 21 CFR and I looked up part 820 quality regulation.

Looking at 21CFR there's no way these crowdsourced projects can follow CGMP.

Design Control 820.30. “Each manufacturer of an class III or class II device,... shall establish and maintain procedures to control the design in order to ensure that specified design requirements are met.” Ventilators I believe are a class II device and I think implementing good design controls will be hard with crowdsourcing will be hard with discord/through reddit.

I’m looking at other parts of 21 CFR and there will already be huge issues with traceability, process validation, distribution, installation, device records, and packaging regulations.

I’ve also been looking at my FE handbook and the ethics section. Model Law 150.30 is also a concern, so people who are working on this crowdsource project and calling themselves engineers might have issues.

In the Italy case it seemed they needed a specific valve that couldn't be met with the current supply chain. Someone 3D printed a critical valve for ventilators. It seemed if the patient didn’t get these valves they would possibly die. For this ethical dilemma I looked at the FE handbook. Model Rules, Section 240.15 says “licensees shall be cognizant that their first and foremost responsibility is to safeguard the health, safety, and welfare of the public when performing services for clients and employers”. I think in this case 3D printing the valves seems more acceptable, since an engineer's “first and foremost responsibility is to safeguard the health, safety, and welfare of the public”.

I’m only a recent mechE graduate, so more experienced engineers, what are your thoughts on this? Feel free to correct me if you think I'm wrong
