Anyone got any information on the Dyson Vents? From what little I can find online they're using their existing digital motor design with slight modifications. My understanding is that their motor works by sending a digital pulse through electromagnets to propel the motor, we've had to remove all their fans from being used near patients due to them causing issues with pace makers and defibrillators. Does anyone know how they're getting round this? I haven't got a lot of experience with ventilators other than first line response, which I feel is going to change quite quickly!!
Another massive number of hospitalized covid-19 deaths, questions: - 1, how many ventilated 2, which type of ventilator 3, with or without the humidifier 4, hospitalized recovery rate
Meanwhile, here is the MHRA spec (.pdf) for the snappily named "Rapidly Manufactured CPAP System":- RMCPAPS
And the thought occurs ... could reported "increases in oxygen usage" in various hospitals be due to CPAP et al ... bearing in mind that the design (sizing) of many PMG systems would have pre-dated the popularity of such equipment?
In the US Ford is gearing up to crank out 500 pNeuton ventilators each day. The OEM (Airon) normally makes three a day. Ford plans to have made 50,000 by the end of July.
The pNeuton Model A is a transport ventilator with built-in CPAP.
The first adapted ventilator design presented by the government’s Ventilator Challenge UK consortium has received regulatory approval. The UK Government has now placed an order for 15,000.
It is the Penlon Prima ESO2, which has been adapted from an earlier (tried-and-tested) design.
The news follows the arrival of Smiths paraPAC Plus to the NHS front line in various locations last weekend. Eighty paraPAC ventilators were produced last week, with production now being ramped up into the hundreds. As an existing device, the paraPAC already had MHRA approval.
Its a very big credit to all who have rallied round to get these vital ventilators into our NHS.
I am somewhat concerned we have the Dysons and many more building this equipment but how many are meeting the MDD93/42 directive?
If they go faulty are we going to repair them or just write them off.
As we don't totally understand Covid-19 how safe are we to de-contaminate these machine, are we safe to do so before repairing .
How long do we need to keep manufacturing will someone tell us once the figures are met or will Supply Chain hold their hand up and shout stop.
God willing when we are over the worsted, things start to settle down what happens to all these machines as we all know the hospitals are going to be flooded out with equipment. Do we bin all the wildcard ventilators or put them in wooden crates and store them in a large storage warehouse.
Hopefully, they won't be used (or indeed, needed) anyway.
I should imagine that any that don't meet the required Standard(s) will end up being binned - although at least one of the Dysons should probably be kept back for the Science Museum.
To be honest, I believe that the dominance of the ITU-type ventilator will soon be on the wane; with modern (sophisticated) CPAP-type machines becoming more prominent.
I think that storing any "contingency" equipment in wooden crates is a bad idea (and I have some experience in this sort of thing). If stuff gets hidden away, and never looked at, then it's unlikely that it will be any good if and when it's actually needed in a hurry. In other words, it still needs PM - not very often, and probably not much; but it still needs checking and servicing every few years. Big storage sheds are OK, but the kit itself is best kept where it can be seen - and counted - by someone wandering around. On shelves or pallets, covered in clear plastic if preferred.
