We have a new group member
• Jordan Smith - expert consultant on all things computer programming
Problem Statement
•Design an Accessible Medication Dispensing Device. The device must be automated, and capable of dispensing drugs only to a specific patient, and with patient-specific doses.
Aims
– Affordable– Dependable – Simple– Safe– Flexible– Scalable
Needs to:–Cut pills into halves or quarters.–Dispense medications.
•Ideally, it will:–Interpret a container’s bar code–Track medication expiration dates–Remind users to take their medications –Track what medications have already been dispensed
Specifications
Bar Code Scanners
• Two types of scanners:– Serial– Keyboard Wedge
• Three types of interfaces:– Keyboard Wedge (Keyboard
Wedge Type)– RS232 (Serial Type)– USB (Either Type)
Bar Code Scanner Cost
• Available Options range between $150 to $1000.
• We will need to spend between $200 – $300 for an adequate scanner and supporting software.
Three Ideas Thus Far
• Conveyor Belt
• Loadable Tray
• Blister Pack
Conveyor Belt
• Made a prototype
• Decided that the design was to complex
• Will need to simplify and redesign
Conveyor Belt
Conveyor Belt Cutting System
Loadable Tray Prototyping
• Built Prototype with epoxy
• Epoxy wouldn’t release from tray, kinda ruined it
• Near impossible to keep razor blades at 90º angle
Loadable Tray
Blister Pack
• Have pills come in standardized blister packs• Pros
– Pills separated– Environmentally Sealed– Ease in cutting and in dispensing
• Cons– Less Convenient, relatively few medications currently come in
blister packs– Not as universal
• We can make it work but requires implementation of blister pack technology
Blister Pack Schematics
QFD
Where do we go from here?
• Discuss different designs with our advisor and a mechanical engineering professor
• Working prototypes • Refine ideas
