A fully automatic pump, with which the desired fluid amount can be pumped with.

The first design sketches were inspired by open-source designs available on the Internet (Wijnen, Hunt, Anzalone, & Pearce, 2014), but didn’t match our quality requirements or functionality requirements. None of the available open-source designs were offering the possibility to go back and forth with the syringe plunger. Most of the designs were experimental, didn’t have a convenient structure and allowed the user to use only one type and size of syringe. This is why it’s been decided to completely re-imagine the pump design with inspiration coming directly from the commercially available syringe pumps. The resulting design is an easy to use device with convenient features that allow the
user to use multiple syringe sizes, an easy-to-use system for the
replacement of the syringe, and a bi-directional pumping
possibility.

Each one of the five parts of the pump has been sketched on paper first, and the dimensions have been calculated according to standard sizes of commercially available screws, nuts, metallic tubes, ball bearings and couplers.
