- British home appliances firm Gtech, which specialises in making vacuum cleaners, has made a prototype of a medical ventilator which founder Nick Grey says can be scaled to mass production within weeks. Made largely from off-the-shelf parts, the ventilator runs on compressed air and can be assembled with a simple production line.

STRONGLY recommend the Real Engineering channel's video on why it is a tad more complicated than this.I KNOW YOUR HEART IS IN THE RIGHT PLACE~. I literally have been designing an arduino based pressure sensor and valve control system to allow patient activated breath cycles. BUT
basically, the need to control Peak pressure and have adjustable exhalation pressure to prevent barotrauma of already swollen alveoli, and assisting with prevention of alveoli collapse. Else there is a legitimate concern for these causing more harm than good.-- humidity is required to prevent lung tissue damage and keeping the mucus and surfactants in the lungs from thickening or drying. Tidal volume control ( size of breath) is needed to be adjustable for the size of person and the stiffness of their lungs (how swollen the lung tissue is).
Use electric drills. Here are more DIY ventilators designs using the Manual Resuscitator:

Adam, obviously you are very knowledgeable about this subject, but can we pull 30k within the next 2-3 weeks of something so technical, this is a last resort device which is better than nothing
@@markjamieson2005 again. I strongly recommend watching the Real engineering channels video. but the short of it is that it actually is better to do nothing.
I am in no way criticizing your efforts or your intentions. rather its very encouraging. but while it might FEEL better to do something than nothing, but after a few hours of over-pressurizing the air sacs at the end of the airways will tear and the patient would suffocate because of the fluids leaking into the lungs. a few hours without a humidifier and the fluids already in the lungs turn to a thick syrup that also suffocates them. it's legitimately more dangerous to use something like this than nothing.
resuscitation bags are meant for the half hour ambulance ride, or if someone crashes and needs to have air until a ventilator is brought over, and on a patient who is either unconscious or anesthetized, so their lungs don't work against it and who's lungs aren't already swollen up. the news has latched onto this one really hard but its not what actual doctors have been saying for a while.
I was working on an arduino based valve control system for patient initiated breath cycles to solve that last problem. if u can get a version of that'd working that'd be a huge step in the right direction. PEEP (peak expiratory pressure) valve can be a manual valve as long as there is a readout tracking the whole cycle that can be converted to cm/H20 of pressure.I couldnt figure out the arduino stuff so for now I've switched to tooling up a face shield frame plastic injection mold, as its what I'm more familiar with.
adamklam1 I share your views and already talked to some respiratory therapists. We are just starting to design an automated BVM device that is triggered by the patient inhalation with redundant safety measures. We came up with a prototype vacuum sensor that uses IR sensor, pressure switch and pressure sensors.. we will be testing the concepts and will share them. PEEP and PIP are also considered. Let us know if you reach to a solution.
@@fadilalsayegh7637 have you done this yet? I would really like to take a look at your design and manufacturing principles since I am also looking to get started with this. Thank you.
All these people using there skills for the greater good is one really awesome silver lining to come from this.

Moving air is the least complicated thing a ventilator does. Controlling pressures is critical. It's the whole point of putting someone on a vent.
Kenneth Pace is it a flawed design then?
That's right. Many people think that a ventilator just pumps air into your lungs and that's it. In reality, it's a complicated system that not only pumps air into the lungs, but also controls pressure, rate. Measure some parameters of the body and accordingly adjust itself.
@@Natashahoneypot They don't say what the machine can do so who knows. It has a pressure gauge on it... I'm sure it would probably keep you alive if you were paralyzed but it's therapeutic abilities are unknown. When lung tissue is swollen, tweaking the pressures a few digits is the difference between walking out and being put in the ground.
I wouldn't want my life hanging on the performance of a garage door opener.
Necessity is indeed the mother of invention.
thank you for your support and caring enough to figure out a way to help others God Bless
Love the ingenuity of the engineers and builders of this world. God bless em we sure need it now.
Speaking as a medically retired electronics engineer, Could the thousands of retired/Not Working electronically minded be enrolled? Just as they have done with the Medical people? it would be a simple task to send out kits and return the item ready to go.
yes this is exactly what is needed in times of crisis. no need for state of the art technology to help a guy to breathe.

This is very inadequate for actually helping a person in critical condition and for recovery. Look up the video by Real Engineering about ventilators
Trump already said “you already got the ventilators you asked for you aint getting more” what a government
Literally, the technology requirement is lower than that of $150 USD drone. I don't know why all US states spend 30K to panic buying this machine. They should set up the simple production line of ventilator
Beautiful. So happy that people are still out there helping one another despite reading the daily doom.
Could you make a video that takes us through the whole proces, where to order the parts, how to assemble everything. That would be great.

Marecheck1978 first you have to buy a Printer. It is probably 4weeks waiting period before you can get one. Could be expensive.
@@4homemail There is no point in buying a 3D printer. This material is rather directed at small and medium-sized manufactories that could assemble such equipment in quasi-wholesale quantities. Remember that the printer alone is not enough. Other elements are needed. The medical ventilator is not just a vacuum cleaner. Still, IMHO, it's the most flexible and cheap alternative to professional medical equipment. All technical documentation is already available.
@@Marecheck1978
Reliability is going to be the limiting factor. Variability is a problem too, because all patients don't require the same volume or rate and getting that wrong can do as much harm, as good. Not saying its a bad idea, but as designed, this is definitely an extraordinary measure and would not be very good for general use.
Thank you ,we need more companies like yours doing what you are doing,saving lives

Are there interim designs, part lists so we can start practicing making them? What URL will they be on? Thanks GTech!

Another British firm adding ingenuity alongside Dyson, JCB, McLarenF1, Aston Martin Racing and even UK based Mercedes F1. Well done each.
Necessity is the mother of invention ...
Next automobile industries should step up and start making hospital beds.
You are 100 % correct..😷😷♥️♥️
Why not... more manufacturers more supply....
Daf gave 1000 electro motors (windshield wipers),and Audi Belgium make air breathing machines from that.
Can they make RTs and doctors too? Who will run the ventilators?
Nowadays everybody must have at least one ventilator in everyhome to combat coronavirus.
The world needs good old fashioned ingenuity now more then ever. We have people at CalTech, NASA and JPL. These guys solve problems and we need a consortium of the world's brightest engineers and doctors working on solutions.
I hope many have already pointed out that the air pump is the easiest part of a ventilator. Heater, sterile humidifier, pressure sensors, variable volume, and feedback regulation- the lungs are delicate. A machine like this would quickly destroy your lungs. Good intentions, I know, but there is so much more to it. Still, a ventilator costs $30K because the manufacturers can get away with it- not because they really cost that much.
As a former Respiratory Therapist that has worked in almost every type of ICU in a major hospital...this design is 100% unfit to be used with any patient. There are severe safety issues here and a standard of care should always be in place.
An "instructables" how to make it and list the products or re-jigged replacements would be great. Plus considering the impending Triage procedure where people with any co-morbidity or existing health problems will be excluded it could be a life saver for many.
Well done guys. Looks good - I was trying for similar. Watching from RSA

@Budget Boost DIY
Did you see this design?
ua-cam.com/video/xdZtMgpxnPI/v-deo.html
It is open source as well. It looks like there are no moving parts that could wear down or fail. The only thing needed from DIYers is the box. Sony will produce 5,000 of the circuit boards a day. I'm sure there are many DIYers who could produce the circuit boards as well when those schematics are released. There is another video about this ventilator that has simple dials so the respiratory techs can make adjustments as needed. This adjustment is vital to lessen damage to the lungs (or I understand, I'm not a nurse). God bless you and the DIY community as you step up to save lives! 💕

@@juliewhite9173 Yes, I saw this interesting project and other DIY types. The main thing is that the design must be functional, flexible, simple and cheap, and this is a difficult matter - the ventilator is not a vacuum cleaner :(
Please, understand the complexity of the problem. It much simpler to pump air, but the problem is how to adapt it to the needs of the patient. Electronic control is the difficult issue
Thanks to all who can help!
Also, that BVM plastic will soften making the volume change...love the idea, love the fortitude we have! keep it up!

Hi Team, Just a suggestion in case if that can help. To reduce the circuitry cost, we might be able to use a transistor-based astable multivibrator which consists of only 2 very cheap transistors, few resistors, and capacitors. The output can drive a relay that can switch the direction of current flow which can, in turn, change the motor direction.
I have my own BVM and ventilator breathing circuit but it’s compatible with select ventilator machines though
That's just plain old good work Fellas. Thanks. Bob From Philadelphia
Except that it's not British idea.

Superb.... please make affordable ventilators for humanity.👍
Is it possible to get to see the full interview with the guy? I would like to know more about their solution.
Mechanical cam type back-and-forth movement is more convenient and use less parts and less electronic means less failure just needed cyclic timer for forward and reverse movements
Best build Iv seen in weeks all day good thinking mate 🙌🏼
where can we get the inflatable tube which contracts and opens up?
Now that’s a Great Man thinking outside the box !
Can you use a rectangle wheel with rollers to push the bag in and out and have several on the wheel so you can compress several bags in a row with one electric motor?
In Pakistan local engineer had made this kind of makeshift ventilator last year to curb rising prices of medical equipment
Yeah this is gonna work! Where does the compressed air come from in a hospital??? Oh yeah, the purified liquified air at the bed, and this gizmo will operate at 16PSIA??? I don't think so...The syringe piston won't last an hour, it's designed for ONE pump. I can get maybe a week's worth of use (14 pumps) out of the one's I use on my lung lavage system, then the rubber seal pulls off the plunger.
I wonder for how many strokes the gaskets in these syringes stay tight.
MetalheadAndNerd ... longer than you will live without it
Not that many, sadly. From experience in using these in veterinary medicine....
a good critique!
As an emergency ventilator, it can help someone out in a pinch, need a steady supply of extra syringes to keep the machine up. Decent trade off
@@RICDirector They are *single use* syringes, but it's great to see ingenuity at work. 👍
They've gone from sucking to blowing.
Well done lads, great job 👍
But where is the pressure sensor? Where is the SpO2 sensor? The computer interface? I heard that the pressure control has to follow a precise curve.
I applaud you. I will pass this on. Thank you all for thinking outside the box....
Another British company that can make a difference. 👍👍👍
Design drawings much appreciated. Would like to build local prototype asap.

we can just use a cpap as a bipap and most newers ones can do this with a simple computer programe.
Is it possible to set the amount of residual pressure left in the lungs with this type of ventilator? With this type of coronavirus this would be very important as allowing all pressure out of the lungs on exhale actually makes the problem worse by causing alveoli to open and close all the time, causing further inflammation and reducing function further. The residual pressure left (peeps) keep the alveoli open and helps recruit more to open, increasing function and reducing inflammation. Giving a far better chance of survival. Simply pushing air in and out will cause further inflammation in the lungs and lead to a quicker death as more and more alveoli will fail to work in the situation of pneumonia.
Only in shifting patients it will be of help other wise proper ventilator is required for long time management
Brits are coming up with alternatives! Needs to be spread globally
The machine they showed in this video definitely does not pump enough air and they need to show a fully working version pumping the correct amount of air. I don’t think that actuator/motor is strong enough for the device.
I need an update to this...
This is the greatest idea out there
@Peter Lustig And what are you doing to help Peter? If you can't help then just shut the fuck up and stop being a little bitch. I'm embarrassed for you
need a air compressor to movite the cylinder. while most household can not supply that. how about change that to be a electric motor?
Brilliant work guys, would a box the size of a shoe box with small fan with filter, and flow swith on breating tube, side vents to stop box over pressuring, side vents to have slider to adjust pressure for patient, light breathing on the mouth tube will activate flow swich and then start the fan to pressurise box and fill lungs with air, just an idea guys
Sounds good! Let's get them in production. Simplicity is always the best way to go. God Bless!

What are you doing about PEEP? Or I:E Ratio?
Meanwhile, Ford in Michigan says it can't achieve volume until June!

@@ericsaez744 u need PEEP and atleast 5cmh2o and otherwise it is totally useless and i am afraid u simply cant using AMBU bag
@@usamazahid1 why is necessary that level of pressure? 5 cmh2o?
Can you give me some details about the vantilater. And how u made this??
Looks goog but it wouldn't work, because once the intratubular line is in the trachea will require an equal amount of highly oxygenated flow of air to both lungs and the pressure has to be equal to both lungs, they are other factors to take in consideration like the size, age, in order to provide the patient the right levels of oxigen. Having said that is a good prototype that could result in the worlds smallest ventilator machine, if they could get those kinks fix.
I appreciate the cause, it looks wrong way though. "reinvent the wheel". The ventilators producers can ramp up their production by subcontract the components or license other capable companies to produce them.
Awesome work! Is there patent restrictions? Is it ok if this is reproduced? What would it take to obtain the list of items needed to assemble it? Thank you!
I want one now, my dad is in hospice and he will need one in time... when my stimulus check comes in. I will share with neighborhood.

Lots of used vacuum cleaners out there. Reverse the air flow and put a mechanical interrupter onto the flow
Would he want to be ventilated or someone he knows be ventilated with this device?
Impressive. I wonder if any way to ventilators with a shared mechanical engine/supplier like a central Air conditioner that is self regulating and could ventilate 100 or even 500 beds?
Each patient could have separate requirement for percentage/volume/litres to be delivered.
A mass system would still require solitary unit calibration.
A mass unit FAILURE would mean mass casualties.
But, it's a good thought.
This will be great for countries or areas without the resources!
How great is this. Thank you so much.
car wiper blade motors can simplify and improve reliability further!!
Pls can you tell me the components used
this is so much simple than other that i see, i am not so sure if that can supply the right amount, mechanicals parts whereout and if that fail, it be sad, but hey better than nothing so props hope something great come out of this we have to survive toguether. social distance no social isolation.
Why not design a larger ventilator vacuum/pump unit that feeds manifold/s and is plumbed to bedside controllers to simplify large needs like a dorm or unit where many ventilators are needed?

@@Samuel-I I think most people think we need corporations, there's other ppl in the world like AvE that have a wealth of information and can implement it too.
No doctor is going to risk pumping air into a patient's lungs using that contraption. If that patient dies the family is going to sue the hospital and the doctor for using equipment that wasn't approved. Good luck trying to prove in court that it wasn't the contraption that killed the patient. This whole thing about building cheap ventilators is a complete joke. Everybody thinks they're smart yet everybody forgets the one thing that will prevent any of these contraptions from even getting through the hospital doors...LIABILITY!

Can I have the drawing of it? Waiting for the reply...
As an engineer, I can see *very obvious problems to this design* that will lead to inconsistencies in air-delivery and reliability issues - which would be potentially fatal and unacceptable in a medical product. *Their heart was in the right place and they made a functioning prototype in 24-hours, but this is not well engineered nor safe for human use.* Pneumatics offer much better ways to move air than pressing a rubber bulb with a plastic disc actuated by a repurposed syringe. We are experiencing a shortage of ventilators, not of pneumatic parts - there is no reason to build it like a Rube Goldberg experiment.
It's almost like it's a low cost prototype of a subsystem, or something

put the balloon in a pressurised box then just put a relief valve on an adjustable timer and pressure regulator on the box... job done !!!
Why is everyone making complex things, look at the old locomotive engine with a wheel and crank, you have the motion you need right there just in reverse. a wheel driven by sewing machine motor or washing machine motor and speed control and a simple arm driven from a pivot point on the wheel pushing on the air bag
Excellent ..where is Q?
I don't get this. How do you keep the balloon inflated? You need to get rid of exhaust air and allow in new air. This means that you need two valves and a pressurized air tank. when intake valve opens, exhaust valve closes, and then air goes into lung; when intake valve closes, the exhaust valve opens, and then air is pressed out by the lung. How does pressing a balloon get rid of the old air? And what is supplying new air into the balloon? The balloon functions only as a reservoir and a device for the pump to press, but what is supplying air and rid air for the balloon?
It seems this device provides pressure to push air. But isn't pressure supposed to be provided by the oxygen tank? Isn't ventilator a valve control device to control when to let high pressure air into lung and when let air out of lung?
