| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 102 === To give medicine for treating a patient, there are three major forms: Inject through skin, swallow from mouth, and inhale through the trachea. By injection and swallow, the doctor knows exactly the dosage of each taken by the patient. However, with conventional inhaler design apparently there is no way for the doctor to see how much of the medicine was inhaled into the body of the patient. Moreover, there is a very important factor that seems to be unattended: the fact that some patients inhale too fast, if that's the case, the medicine might not go to the lungs but the stomach or the brain. So, not only how long the effective inhale but also how fast the inhale (after, during or before) the medicine came out of the medicine powder container.
An intelligent device has been developed to automatically deliver medicine at certain time point, after detecting the inhaling starting time. May be more importantly, with more accurate and effective dosage information from this potable intelligent device, the drug tests of pharmaceutical companies would be more dependable, and the suggested dosage to the patients of different age would be more reliable.
In this study, an automatic inhaling device was designed with the help of re-design technology. To optimize design of the gear-cam actuation mechanism, the Magic-AHMA® and FARCENT® air fresh spray mechanism were carefully studied. Advantages and shortcomings of both mechanisms were compared. Reverse Engineering technology was applied to make 3D design for our actuation mechanism.
Industrial product design techniques were used to make the entire intelligent inhaler more user-friendly and more appearing. Good design examples were referenced our better product with Re-design technique.
Moreover, plastic injection molds were designed for major components. Moldex3D software was used to simulate the molding process and best injection molding parameters were determined.
