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
