It's nice to see that the community is exchanging ideas on whether it would be possible to make a contribution and help in the current crisis.
But it would be nice if everyone could keep in mind to stay polite in the discussion, thank you

Are so now you are talking about hand bagging someone, no control is required for doing this, and there is no shortage of this type of Ventilator, critical care is where they say they will have a problem but there are 160,000 critical care Ventilators in hospitals in the US and 12,700 in storage that have not been released yet
Hospitals are not prepared to pay for them, they want them for free or supplied by the government
Even with a critical care Ventilator you still need a Respiratory Therapist and a Doctor and a nurse
Here is an article on Ventilators that may help you understand what is needed to treat a patient, this is very basic https://health.howstuffworks.com/med...entilators.htm
These Bags can help but there is no shortage of this type of Ventilator and will not help anyone once they reach critical care

That's about as far as I got with my thinking as said before.
A mechanism to squeeze / release a CPR bag using axis control with a valve type unit to fill it with some oxygen after each compression. This would help free up the care workers from having to do this themselves so they could treat more.
But this is in no way a substitute for actual ventilation.
1) It's keeping us off the streets and away from other people so we hopefully stay healthy and don't contribute to the shortages.
2) I'm semi-retired and in the high risk group. Not too much else to do but self quarantine and hang out online.
3) My machines are running every day making parts for completely unrelated applications. And if needed I could and would make parts to help out directly, but as it stands now there is not much meaningful that I could actually do based on the capacity that I have. For the moment, the large manufactures that have the capacity and infrastructure can handle the load. If it comes down to small shop operations being needed to keep up with the demand then I think we have some larger problems.

With all due respect, my idea is sound. It can work as described, I merely dealt with a troll attack so those in need won't be swayed. I don't mind when people disagree, but as you can see I had to deal with an entity that had no intention of agreement or even learning for that matter. We are in a difficult time. Sound ideas can save lives. I thank you for your concern and I apologize for my way of ridding the poorly intentioned.
The whole point is you have no examples to show a working model not even a sketch so talk is all you are doing with nothing to back up any of your talk I'm still waiting for your code example in any form you want use post
This is what it is all about people that have been doing this from the start when they new there was a problem there are already many solutions that work here is one

Get to know what you are talking about do the Math, roughly 80% don't need a Ventilator of any kind so how short are they of critical care Ventilators if you live in the usa then they have enough Ventilators at the present rate of infection what the health care worker's don't have enough of are masks and gowns
Mild symptoms
When it comes to COVID-19, the term ”mild symptoms” can be a bit misleading. A mild case of COVID-19 might simply feel like a cold, or it could include symptoms as serious as fever, cough and pneumonia ? but not to the point where you need to be hospitalized. Roughly 80% of cases are mild, while the rest are classified as “severe” or “critical.” A case is considered severe when you need oxygen or a ventilator to breathe. Critical cases involve respiratory failure or multi-organ failure.
SARS-CoV-2
“SARS-CoV-2” is the official name of the virus that causes the disease COVID-19. Not a lot of people use the official name, instead saying “COVID-19” or “the coronavirus.” Even the World Health Organization has backed away from the term “SARS-CoV-2,” saying instead “the virus that causes COVID-19” in order to avoid confusion with the disease SARS, which caused an outbreak in 2003.

Your idea is far from sound . For one you mention Ontario , Ont and Canada in general has some of the strictest regulations in regards to healthcare and healthcare products . take a look around oshawa if you want to see how the real world works . The notion that a windows based cnc can be used to run your idea in the large plants around ontario will have you laughed out the door , since most industrial manufacturing machines do not run on windows .
You suggesting using a lathe with a modified tapping is beyond reality , which can easily be interpreted as a severe lack of knowledge in regards to cnc , or , in other words simple robotics
as I said before you don't know my background . I've been in manufacturing for 30yrs . I spent 13yrs of that in shops making medical products , many I've designed and many are still in production today . the red tape is much thicker than you could imagine . The products and assemblies we made and designed fell into the gray areas because there was too much bureaucracy involved with the red tape products . Ventilators and life saving products fall into the red tape district
If thats not enough then the contamination in most machine-shops should be enough to prevent throwing some poor victim into .
If you want to hook up an emergency bag to a cnc for one of your family members then by all means go for it , but the rest of us will likely rely on a proper medical system
Yes as I said is no substitute and is not what is needed for a patient that needs critical care
The machine like this would have to be able to sense what the patient needed in terms of oxygen input and be able to measure the pressure in the lungs and many other signals at the same time, which is not possible without a sophisticated algorithm that can be controlled by a computer, in other words complex software which is used, that has taken the ventilator manufacturers years to develop

Again, more of the same. I realized on the weekend I was in the wrong place trying to discuss writing underlying programs in CNC equipment to general operators. I've since moved on to discussions with a group that write software for various functions including robotics. A lot of ideas on the many ways this could easily function are a result. Thank you for trying though. My mistake. Simply the wrong place for this discussion.
Hi, I'm retired now but if I recall we had some similar machinery. I've always loved that handle, aren't we all. I usually read through this forum every month or so to see whats happening, Anyways, I saw your name and read through all the comments, It appears you were in the wrong place for the science. People trying to change your narrative from an emergency situation to a medically approved device didn't help the conversation. I come with good news. My grandson is presently enrolled in a robotics class. Entry level, His teacher was inspired by a story out of China where a 15 year old kid saved his neighbors life. No respirators were available and his neighbors were hand bagging their mother. Evidently the kid was into robotics and had a kit he built a robotic arm from, This kid modified the arm to push the bag and programmed it to push the way it had to. He saved a life. My grandsons teacher has a group of students making this same device as a project to learn from. Great teacher! Anyhow, long story short, you aren't the only one with this brilliant idea. Search homemade respirators on youtube. My grandson showed me many are actually doing what you suggested though they don't have the luxury you have in a cnc mill ready to program to push a bag. My grandson was very interested because he used to help me in my shop and loves machinery, smart kid, he chimed in they should set up portable hospitals beside industrial plants, they could run airlines, you could put more than one bag on a mill table he says. Anyhow, you have a couple fans here. There are only leaders or followers taxslave, you're not a follower. Great innovation!
there are also instructional videos on youtube in regards to making face masks from bras , even though health officials continue to repeat that the general public should not where masks .
Further to my earlier post,this news item has now appeared:https://us.cnn.com/2020/03/30/tech/m...rus/index.html .Please don't bother telling me they aren't the all singing,all dancing ventilators but they are intended to save lives and leave the more complex machines free for those who really need them.I was a little saddened to learn that the makers of the more complex machines were uncooperative on the basis of protecting their designs.
Do you already know this challenge? I was wondering if it could be of interest to you!?

Great attitudes can't, can't, can't.
Same attitudes I see with printed face masks when the machinist community gets involved. Not FDA approved, won't pass fit test....
Seems like a group a fools that would die because the 19mm wrench is missing as your tripping over 3/4's.
I wish I could find the janky contraption MIT is experimenting, a cable attached to a stepper motor shaft acting as a cable drum. The other end of cable attached to a paddle squeezing a ventilator bag.
Sure there not cnc controlled but many cnc like materials in there build.
Check out this
Yes. Basically a version of a C,P,A,P unit (or something like that). It might help some people but again is not really a substitute for the critical.
But on the flip side what will happen is, while we piss about 'testing' and faffing (as usual) they'll take orders from worldwide. By the time it comes to get some in the NHS ourselves -, There'll be a backlog and they'll tell us we have to wait 5 months even though it's made here!!!
The problem with this is there is no shortage of this level of Ventilation, and with your suggestion you would hurt of kill more people with this uncontrolled method of bagging
Any type of bagging can help at the none critical stage, once the patient reaches a critical stage when organs start to shut down only 1 in 10 are being saved with critical care Ventilator use which would be imposable to do with any CNC or a machine under robotic control
There are many different devices already being used and there is no shortage at this level of treatment
This simple CPAP device does all what you are talking about and more, and there is no shortage of devices like this
Mactec54
Glade you found somewhere to post I still waiting for the code you said was so easy to write or a skitch of how you would make a CNC machine do the job of a CPAP unit, all you have done is talk
Here is a CPAC package, anyone can buy one, and there is no shortage of them, this will do a better job plus more, than any CNC Machine or Robotic controlled machine
Note there is no shortage at this level of Ventilator requirement

Thank you for the kind words. It sounds like your grandchild is a motivated young man, great to hear. I've always ignored negative thinkers. There are a lot of people out there that can speak only of ways something can't be done. I learned this when I was 11 years old, I adapted one of those old gasoline washing machine motors with the starting pedal to motorize my bicycle. My first machining job was on my uncles Atlas bench lathe making an aluminum drive wheel that fit the top of the tire. I had many naysayers, my brothers, schoolmates etc but the glory was all mine the day I went flying by them all on my motorized bike. I have so many gizmo's I've made over the years I need another shed.
Once I became aligned with the robotics people, they to have heard many innovative ideas out of China during this crisis. They also pointed me to the Youtube postings. Its great to see our inventors combine forces around the world and fight this crisis. I must say these robotic people are among the most inventive and motivated group I've ever seen in my life, many are very young, great to see. Almost zero negativity in that crowd. To anyone reading this. If you've never seen the robotic kits available for kids these days, go check it out. Trust me when I say get your child into this, boy or girl, many seem to love this. Its the future.
Again, thank you for the kind words and take care of yourself in this horrible crisis. Never let anyone tell you something can't be done.
the main reason that most people with covid are gasping for air is because of a lack of oxygen , due to extensive damage to their lungs . An emergency bag that is hooked up to a push rod which is pushing room air into the lungs is not going to give the patient the oxygen they need . As mentioned these devises may work for non critical but these simple devises are a far cry from the silliness of connecting a bladder to a full on cnc machine
