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 Specifications

Aims – Affordable – Dependable – Simple – Safe – Flexible – Scalable Specifications 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

Bar Code Scanners • Two types of scanners: – Serial – Keyboard Wedge •

Bar Code Scanners • Two types of scanners: – Serial – Keyboard Wedge • Three types of interfaces: – Keyboard Wedge (Keyboard Wedge Type) – RS 232 (Serial Type) – USB (Either Type)

Bar Code Scanner Cost • Available Options range between $150 to $1000. • We

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.

Blister Pack • Have pills come in standardized blister packs • Pros – Pills

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
