Works for what I use it for—but...

If you have tattoos you won’t have as great an experience with it. I mostly use this where I don’t have any now, because trying to see veins through ink with this just highlights the tat in white like one of those invisible ink lights.

The picture is extremely faint and grainy, but it’s great for a general idea of where to look. I don’t really love that I spent so much on this, but it’s definitely not worth deleting. I’ve gotten some good help from this thing and I recently recommended it to a friend too

Costs less than your lunch will today.

So from time to time in the back of the boo boo bud I struggle to get a vein on the unstable patient that is circling the drain.

About 3 years ago I was drinking one night and stumbled across the vein seek app. I down loaded it, it cost me $4.99. I played with it at home for a little while and thought it was pretty cool. Still not sure how it works. So after a few months I picked up one of the above described pts. I stuck and stuck and stuck some more. I finally remembered I had that app, might as well give it a try, being as my pt was about to die, everything was worth a try. Sure enough I turned it on, adjusted the contrast, and boom, all the close to surface veins lit up. I sunk a 24g IV into one of the biggest veins I would find and ended up getting the pt stable enough to transport.

I’ve used this app on multiple hard sticks since. I’ve even broke it out in the er to help them out on multiple occasions. So to all my fellow providers, here’s a tool that you will always have on you and I highly recommend buying it. It may very well save your pts life.

Better than expected!

I’m a paramedic and was looking for a cheap alternative to a vein finder for patients that are “hard sticks”. I just downloaded this and I’ve been using it to look at veins on myself and my partner and it seems awesome! I’ll admit that I wasn’t expecting much from an app, but this app already exceeds my expectations. It’s not magic and I don’t expect it to show every single vein, but it DOES show veins on my arm that I cannot see. And on veins I can see, it shows which direction the vein goes. I have not yet used it for starting an IV, but I will definitely be using it as it will be nice to have a place to start on patients where you can’t seem to find anything. I imagine this will (at the very least) give a good idea of where to start. I also see this being useful when you miss an IV and the vein feels like it’s right next to the needle to potentially save the IV and save the patient from another IV stick.
