Medical prototype. My kid was in a hospital recently, and they had to put him on an IV. The current practice here is to place a support Under the wrist, tape everything up (for immobilization), and have the IV on top of the wrist. The problems we encountered were:

  1. No protection for the top of the wrist where the IV was, causing much anxiety on my part on whether the dude was gonna knock his wrist against anything and dislodge the IV needle, etc (wince!)
  2. Total lost of dexterity in the hands due to the support block

This prototype proposes to accomplish the following:

  1. immobilization of the wrist from the top instead, secured by velcro bands (currently testing using velcro cable ties)
  2. top of the wrist is protected by the Y arms of the brace, while still allowing the palm area to be secured by yet another velcro band
  3. Fingers can still move (a lot more than before), without compromising the IV placement
  4. A lot faster to deploy (dude had to change his dressings 3 times in five days, and each time I freaked out more than he did :-P )


  1. This design is NOT cupcakable (new word, boys and girls!). I had it printed and shipped from Shapeways.
  2. There are notches/indents on the Y-arms to allow the ends to be snapped off in case customization is needed between adults/children

i need one of these after my wrist rebrake op i had on monday!

Very nice. One improvement you could make would be to make the support have a slight longitudinal curve to better fit a human arm. I would want a version that uses medical tape and not velcro, because the velcro may have to be sterilized which may be hard. Also if you have velcro you will need to keep extra velcro straps handy in case they are damaged but you already have medical tape nearby. Finally velcro can slide up and down your arm while medical tape cannot.

Next you should definitely talk to a nurse or doctor, because they probably have a good reason why they support the hand from the bottom and not the top. Keeping the whole hand immobile may be essential. Just looking at my hand I can see stuff move around near my wrist I wiggle my fingers around

Your device is impressive and that wrap is terrible. Seeing the STL opened in ReplicatorG makes me think this could be redesigned as a multi part print.

Again -- this is Genius! You are AWESOME!

AWESOME! This is what makes thingiverse great.

PS I hope your kid gets better soon!!

This is amazing and seriously inspirational - thank you!

I'm impressed because I've absolutely "been there" before. I have a condition in my legs that ... oh forget it, no one wants to hear my medical issues ;) Suffice it to say that I have had to keep an IV in my wrist for days at a time, and it's a pain. And yes you are always worried about knocking the port, especially when doing things like having a shower.

And it's great too that we can get it printed at shapeways! Thank you!
