The Gtech effort is a brilliant example of what "Men in Sheds" can do.
We would probably call it an "automatic bag squeezer". Note that it pushes out a fixed volume. It may be easy to modify the design to offer an adjustable volume. It looks very similar to the one described here.
Needless to say, it lacks many of the refinements required by the MHRA RMVS.
Meanwhile, does anyone know how Government plans for the Rapidly Manufactured Ventilator System are progressing ... have they issued the UOR* yet?
Does'nt look like it Geoff. A consortium called The Ventilator Challenge UK aims to manufacture medical ventilators using two existing designs. One of the models is based on an anaesthetic ventilator made by Penlon, which is bulkier than those normally used in intensive care wards. The company's product chief previously warned that asking non-specialists to make ventilators would be "unrealistic". Smiths' portable ParaPac ventilator is the other machine the group aims to manufacture.
Penlon? What's that ... the Nuffield (200)? ... may as well dig out the Manleys!
I like the paraPAC ... but surely that's a transport ventilator?
I thought we were supposed to be thinking in terms of ITU?
Hopefully, the worst of the crisis will have passed before the first mongrel ventilator gets delivered. I have just heard that China plans to lift the Wuhan lock down on 8th April (two weeks time).
Meanwhile, in other news ... we hear that the UK Government has ordered 10,000 ventilators of a new design from Dyson.

And alongside a team of engineers in partnership with Cambridge-based science engineering firm TTP, Sir James has announced that in just ten days the design for the "CoVent" ventilator has been completed and is already awaiting regulatory approval so manufacturing can commence.
Emailing staff regarding the design, Sir James explained that the team utilised the technology in the air purifier range of Dyson products and that it was powered by a digital motor. Also, the new ventilator is battery-powered as it needed to be possible to use on the move and in field hospitals. It also obviously needed to be safe, effective and efficient in conserving oxygen.
The first hurdle, designing a medical product under pressure and in a short amount of time, has been completed but as Sir James says, â€the race is now on to get it into productionâ€. The company is also looking at making the "CoVent"’ ventilator available internationally as other countries are currently in short supply of medical products, namely the much sought after ventilators.
