I had to take my dad to the hospital yesterday, and he's staying a second night now. So I didn't have enough time to upload the 20th machine on the 21st. I'll make up for it sometime this week.

Anyway, obvious inspirations here, this is an auto needle, with a spring mechanism and vacuum abilities, this mechanical needle can extract blood samples while at the same time injecting an entire regimen of medicine in a single double jab. I imagine kids and those with trypanophobia would be grateful for such a minimally invasive gadget. I know several soldiers who would at least, lol.

Anyway, hope you enjoy, sorry it's not much today.
