  2. Team Introduction & Roles P15073: Autonomous IV Stand

  3. Agenda • Background • System Analysis • HOQ Relationship Diagram • Functional Decomposition • Concept Development • Engineering Analysis • Proposed System Level Design • Risk Assessment • Test Plan • Updated Project Plan P15073: Autonomous IV Stand

  4. Background - Problem Statement The goal of this project is to create an autonomous IV stand that follows patients. Compared to a traditional IV stand, additional improvements will be made such as reducing its footprint and enabling it to carry more IV bags. Deliverables: • Create a simple and ergonomic system for patients, and medical staffto use and manage several different IV bags and medical devices for each patient. • Create a prototype of the autonomous IV stand and perform significant testing to verify the design and safety. • Meet FDA standards for an IV stand and other similar medical devices • Reach stage of clinical trials • Produce a marketable product P15073: Autonomous IV Stand
