Team Vision for Problem Definition Phase

During the Problem definition phase, our goals include using the PRP to highlight the objectives of our project and to identify information and details that will need to be tracked during the remainder of the semester. From our PRP we were able to draft a problem statement, identify our stakeholders/customers, draft customer requirements and draft engineering requirements. This information also allowed us to prioritize tasks and collect data that will be useful during our design phase.

Project Summary

The Rochester-based organization Haiti Outreach: Pwoje Espwa (H.O.P.E.) coordinates mobile clinics in remote areas of Haiti that provide residents with laboratory services. The isolation and lack of electricity greatly hinders the mobile clinic's ability to conduct laboratory tests, particularly through centrifugation. The medical centrifuge is a device that uses centripetal force to separate heterogeneous solutions. A working model produced by RIT students in 2015 satisfies most of the lab requirements but does not satisfy the hematocrit protocol.

The purpose of this project is to find solutions for last year's centrifuge design flaws and to create a new design that is able to satisfy the hematocrit protocols. The new design will improve issues concerning the centrifuge weight, aerodynamics and ergonomic concerns. The result would be an easy-to-use and lightweight centrifuge that will be able to effectively assist the H.O.P.E mobile clinics and the citizens of Haiti.

What is a Hematocrit Test?

The hematocrit blood test determines the percentage of red blood cells that may be present in a patient's blood. Blood is composed mainly of red blood cells and white blood cell suspended in an almost clear fluid called serum. The hematocrit test indicates the percentage of blood by volume that is composed of red blood cells.
