3. Project Background Warfarin is an anticoagulant used for blood clotting medical conditions. Dosages of warfarin need to be frequently adjusted to maintain effectiveness. For the first few months of the regimen, adjustments are made based on weekly or bi- weekly blood test results. This requires frequent coordination with the physician, patient and pharmacist.

4. Problem Statement Frequent coordination between the physician, patient, and pharmacist is –Time consuming –Inconvenient –Increases chance of dosage error Solution: A real-time adaptive system needs to be developed.

5. Fundamental Concept Using a computer, the doctor programs the daily dosages for the patient. This schedule is sent through the internet and connects to the automatic pill dispenser. At a designated time, the unit will sound an alarm, reminding the patient to take his/her medication. User pushes a button and the correct combination of pills are dispensed. Patient brings device to the pharmacist to be refilled.

6. Objective / Scope Create a prototype warfarin dispensing device Unit used for demonstration of concept Must reliably dispense medication in accurate doses Communicates with physician via a computer interface Equipped with operating checks and alerts Easily refillable by the pharmacist Easy to use and simple user interface Spill-proof design Minimize future manufacturing cost

12. P07009: Product Development Process Phase

13. P07009: Current State of Design Design meets all customer needs All subsystems have been designed and modeled Design meets engineering specifications for full system and subsystems except: –Design Size > Desired size of 6”x6”x6” On target to meet project budget of $1850 except: –Potential overrun on cost of electrical components due to intermediate customer design modifications (Color LCD) Budget COG (ea) = $325 Actual COG (ea) = $525 Mitigations: –Customer approved larger prototype design package –COG changes budget plan: Customer approved color LCD display
