Not really about the History of Biomed, but surely a footnote to it, it's sixty years now since the invention of the transistor. So, enjoy this link!

And here's another one! Interesting to note that the first transistorized computer was the Metrovick 950, which had origins in Manchester University (hardly Silicon Valley, then). Of course, Metropolitan-Vickers is yet another once-great British manufacturer that is sadly no longer with us. I don't think they were ever involved much in medical equipment, although I would love to be proved wrong on that one.

Edit Reason: The Metrovick 950.

Vickers. One of the many proud names of British engineering (history, that is). The air is a lot cleaner around the River Don these days, though, I'll have to admit.

Edit Reason: The River Don passes by Tesco's in Rotherham.

Word of warning, if you are accessing this link through a dumb terminal ( Politally Correct term is Thin Client  ) at work, there's some HTML coding that slows down your access. I'll have a look when I get home to my proper PC!
Keep finding those gems on the 'Net, Geoff!

Before the IP3 and IP4's the first electronic syringe pump I remember repairing was the Rocket Of London Microinfusion Pump which had large nylon cog wheel and rachet inside!
Anybody else remember them?

Oh yes, Kawa. I seem to recall working on the Handley a couple of times. They were grey in colour, if my memory serves me well.
But what about when our lovely nurses had to make do with infusion controllers? Anyone remember the Frenshore IC-2, or my favourite, the Ivac 231? 1 to 69 drops per minute, and an achievable accuracy of 2%. No need for IDA's and Infutests back then. And you'd be lucky to have more than two in the whole hospital. The work was a bit less hectic back in those days.
If (like me) you're interested in "classic" medical equipment, better keep an eye on this link. Notice the Physio-Control Lifepak/33 - the first "modern" defib, and the (pre-Ohmeda) Biox II pulse oximeter (brilliant)! And, how about a nebulizer dating back to 1915? Wonder if it needs a service yet? (Personally, I doubt that date. It looks much later than that to me. For instance, I see Phillips screws, and I doubt that they were about during the First World War! My guess would be nearer 1965.) Double-click on any of the pictures for a closer shufty.
