Track: Design and Analysis

Abstract

A metered dose inhaler (MDI), was modified to facilitate discharge of vaporized medication. Several designs were considered using simple machines and associated parts like levers, gears, handles, etc. The final design includes a modified actuator and incorporates several of the ideas developed in the alternative designs. A handle (like a bicycle brake handle) attached to the actuator body is squeezed and compresses the canister containing medication. By utilizing leverage, the force necessary to discharge the vaporized medication from the nozzle of the canister decreases. the handle design reduces pressure on the hands and the inhaler design includes a small spacer directly underneath the gas canister which improves the efficiency of use. The final design is functional and solves the problem posed by standard MDI’s. It is relatively inexpensive and aesthetically appealing which makes it a competitive product on the market.
