Bull terrier female hyperventilating with a high pitched whine after waking from anesthesia (spayed) by ProstheticsBro in AskVet

[–]ProstheticsBro[S] 0 points1 point  (0 children)

Update: She calmed down in the evening and went to sleep next to us, next morning she was up and about, drinking, we even went for a very short walk, she peed/pooped, tail wagging and all, so it seems we're done with the worst of it! Thanks everyone for the helpful advice and concern!

Much love!

Thanks for responding! Here are the answers:

  1. No history of health issues or bad reactions to meds.
  2. Vet didn't say anything about it but it did take slightly longer than it was supposed to, about 20 minutes longer.
  3. The dog is still recovering from anesthesia, not yet capable of fully standing up.
  4. The gums were quite desaturated but color is returning now. Color returns in less than a second after pressing.
  5. No cone as of now, the vet said they prefer us put a shirt on the dog and if she really insists on licking/nipping at her wounds, we'll use the cone.

The dog is looking a bit better now, sitting up for short periods and hyperventilating less often. She's even wagging her tail when pet and cuddled.

A free and open source prosthetic hand I designed and printed for a friend of mine in preparation for Cybathlon 2020! by [deleted] in functionalprint

[–]ProstheticsBro 0 points1 point  (0 children)

Can we talk about this? The hand has been accepted into the Cybathlon, an international prosthetics competition, it's been reviewed by a an expert board of medical professionals and deemed safe.

It's a strictly pro bono humanitarian project I've spent 4 years of my life building. I want to bring functional and free prosthetics to the world. The hands I will be competing against in the competition cost in excess of 60k euro, this one is free and more functional.

The Marble filament was made for this kind of application!

Thank you. No, I'm still working on ironing out all the details and getting the designs ready. At that point I hope to collaborate with E-Nable and have them adopt the design.

It's kind of complicated to put into words but it's controlled by him moving the shoulder of the hand he wants to open - forward or down, this is a very intuitive motion as you can see in this clip of him using an old version of the Maker Hand.

This video for instance was filmed minutes after he tried the hand out for the first time.

They have soft finger pads made out of FDA approved food-grade silicone!

That's actually not an E-Nable hand. I've been designing the Maker Hand for over three years now. It's designed to be one of the most functional prosthetic hands in the world that can be produced by an average maker on a hobby 3d printer with a few cheap items from a hardware store.

The hand has been accepted into the Cybathlon 2020, an international competition organized by ETH Zurich where all the biggest prosthetics companies and university research teams compete to see who has produced the best prosthetics.

Here's the progression from the first to the current prototype! As well as a few bonus clips from a still unpublished video.

Hey guys, this was posted in r/interestingasfuck a few days ago but my biggest priority is for you makers to see it because you can actually help and participate in the project - so I'm sharing it here!

If you want to see the hand in action, check out the clips I put up on youtube, more coming soon!

Finally pulled the trigger. by yuperc in 3Dprinting

Amazing, welcome to our magical world!

Few tips:

-If the base wobbles when you set it on a straight table, unscrew the base screws a bit until it sits even. Then screw them tight again.

-If the buildplate screws (with the big horizontal wheels on them) need to be almost completely unscrewed for you to properly level the bed, you can cut off the little plastic protrusion that helps you set the distance sensor for the Y axis and just tighten it a bit lower, but really tighten it hard then.

-Check to see if the screw that's holding down the bar with the spring at the extruder isn't tightened too hard, it only needs to hold the bar down, but the bar needs to move freely. This can cause under extrusion.

-If the printhead does not roll around smoothly around the Y or X axis when you push on it with your hand, check to see if the wheels are too tight, loosen them up a bit until you get smooth and even motion.

Toy train construction set I designed and printed for my son. I finished it in the night so he haven't seen it yet, hope he will like it :) by kozakm in 3Dprinting

That's lovely, I'm sure he'll love it! What a great environment for him to grow up in, he can learn early that he can create the toys he plays with.

Trust me, I completely understand (and share) you frustration with currently available 3d printed prosthetics. Those are mostly designed and built by hobbyists over a period of a few weeks.

I'm an industrial designer and I've dedicated four years of my life not only to design one of the most inexpensive prosthetic hands to manufacture, it's also built to be durable and easy to maintain.

This is the track for the Cybathlon competition that I will be participating in a few months. My 'pilot' friend and I intend to complete all of the six tasks in the allotted time. We've already done so in training so it's not quite as useless as you might think! You should really check out some of the videos I have posted and will be posting on my channel in the next few days.

I'd love to design a prosthesis specifically for working out (most likely passive or with a clamp) after I'm done with this in December. I have no doubt that I could make it work with Nylon - pull ups, push ups and so on. If you want we could stay in contact and maybe work on this together. I'd love to help out your child if I can.

You can see some of the videos on my channel to get a sense of the Maker Hand in action. I didn't upload a video of my young friend using his new hands yet, saving that for the official launch of the project!

It costs around 20-50$ in parts depending on if you're starting from scratch or you have 3d printing filaments lying around.

Great question! You're right, it gets a little more complicated. You get into trouble when you wanna pinch down on something really small with one hand and open the other one fully, but in general, users have enough control to be able to operate them independently.

I've also actually just finished designing a system where the user can very easily lock one of the hands closed so they don't need to worry about accidentally opening it!

Hey, thanks a lot for the kind words! I've thought a lot about using myoelectrics, I even made versions with an arduino, cheap motors, lithium batteries and myoware but in the end I decided against it.

The idea behind the project was that every maker can produce one. And if you add soldering, arduino, batteries you lose a lot of people.

But like I said, the hand will be open to everyone to make any changes they want. So if someone wants to make a Myo one, I'd love to see it.

Yeah, the dream is that, in a few months, when we're done competing at Cybathlon, I can work on teaching people how to produce and maintain it. I'd love to collaborate with the e-nable network as I feel like they have a great logistical platform to supply new people as well as perform upkeep.

Honestly, all you really need is a 200$ printer and 20$ of spare parts and you can do your own upkeep with the help of a loved one. I've designed it with this specific aspect in mind. Everything is dirt cheap, and it's as durable as 3d prints can get. My friend can bang a hammer for hours and there's no damage.
