Syringe pump

thingiverse

A fully automatic pump is designed to efficiently pump out the desired fluid amount. The initial design inspiration came from open-source designs accessible online (Wijnen et al., 2014), but these models lacked the quality or functionality we required. Open-source syringe pumps didn't offer a reverse function for the plunger, nor were they compatible with different types of syringes, thus we completely re-designed the pump to incorporate features from commercially available devices. The resulting pump is easy to use and boasts a user-friendly design that enables users to utilize multiple syringe sizes. Users can replace the syringe with ease thanks to a hassle-free system. Each of the five components in this innovative device was initially sketched out on paper, with calculations done according to standard measurements for screws, nuts, metallic tubes, ball bearings and couplers found in commercial supplies. Below are step-by-step instructions for creating this model: Firstly, AutoCAD CAD software (AutoDesk Inc) is used to 3D design the five parts that make up the pump. Each part of the design corresponds to one of the five unique components in our system: the base plate features the syringe and motor on separate sides, containing hollowed-out areas for various screws, guiding rods, ball bearings, and z-couplers. The plunger holder consists of two main sections - the initial part contains a screw connected directly to a motor which then powers forward and backward movement, facilitated through the inclusion of slots that hold down two adjustable nuts along an axis allowing parts to glide backwards and forwards smoothly without obstacles preventing their free passage. Lastly comes the syringe holders – they ensure a firm grip around existing syringe sizes so it securely attaches them onto supporting elements attached within base plate.
