Question About Extracting Settings from an IV Pump

Postby beaner011 » March 2nd, 2017, 3:41 pm

Hey everybody,

I'm a veterinarian and am reasonably tech savvy, but no hacker by any means. I was wondering if I could get some general advice/guidance on an idea.

In human medicine, there are fancy (and very expensive) IV pumps that can connect up to a wireless network in order to communicate with an electronic medical record. I've been trying to figure out if it would be possible to make a cheap "wireless module" of sorts for a much less expensive veterinary IV pump. A pump like this...

https://www.heska.com/Products/IV-Pumps ... -Pump.aspx

I'd like to be able to somehow get the current settings for the pump (current rate, whether it's running or not, amount infused, etc.) and spit them out to a web server that could then be used to generate some sort of browser interface that would allow me to centrally/remotely monitor all the pumps currently in use in a clinic. These are not "smart" pumps at all, but I figure they at least have to spit out those settings to the LED display? What I'm wondering is if anyone has a general idea of how those settings might somehow be intercepted from the pump? Would it maybe be possible somehow with GPIO on a Pi?

Thanks in advance for the help!

It's an interesting project. One way is to interpose the Pi/etc between the buttons/display and whatever micro is inside the unit.
Until we evolve x-ray vision, the first thing that is needed is a photographic 'peek' inside the unit showing the circuit board, connections from the board to the buttons and display, etc. If a schematic is somewhere in the manual for the unit, that is also very important.
failing that, access to a unit for a day would be very useful. It can even be a dead/broken unit, just to be able to reverse engineer the circuitry.

Thanks for getting back to me. Have to see if can get ahold of one to play with and get some pictures.
