Most developing world hospitals do not possess operating suction machines. The main problems
are the lack of available spare parts, the cost of a replacement unit, and dependence on consistent
electricity. The objective of this project is to design and develop a medical grade aspirator that can be manufactured inexpensively from locally available materials. Along with the device, an instruction manual will be produced to allow for proper usage and care in the future.

Final Prototype
Our final prototype uses a water jet eductor, constructed from PVC and brass fittings, to achieve suction. When the prototype is connected to a garden hose with line water, suction is produced at the brass fitting on top, which is then hooked up to the collection vessel and autoclavable suction tip.
Water Jet Eductor
This is a cross section view of a water jet eductor. Water comes in through the nozzle at the top and is collected at the bottom. Suction pulls air through the hole in the side.
