3D Printed Gadget to Find Veins

Since a few years gadgets that provide help to find veins have been available. This should make blood sampling or the use of injections and syringes much more comfortable for the patient.

Veins transport the used blood back to the heart. For injections, syringes or blood sampling it’s common to use veins. But often it is not easy to find a vein especially when the doctor or nurse is under time pressure or when the patients are children. A few years ago some resourceful developers had the idea to find veins with infrared light. Therefore a light impulse is sent to the skin, goes through the skin and is reflected by veins. With this technique it’s possible to detect the exact position of veins. There are already gadgets with this technology on the marked but they are often very expensive and so it’s not very common that this technology is used.

Now developers have thought about exactly this problem. After a few months of development in their free time they have published their final design. They got it working without complex electronic or other complex or expensive parts. They only used a 3D printer (ABS or PLA will get the job done), a 9V battery some Near-Infrared LEDs, resistors and a switch to turn the device on. Everything together will cost less than 25 Dollars.

A video shows how the device works and if you are interested a building instruction is available von Instructable. This projects show pretty well what can be done with a simple 3D printer and a little bit of creativity and it was praised on Reddit very often.

It’s sort of a way to show the finger at the government, greedy companies, and so on and post them free
