Device Description
The goal
of InhaleSur is to deliver a reliable dose of bronchodilator by ensuring that
the medication is sufficiently shaken prior to delivery. In order to do this,
the device senses when the user has shaken the inhaler with enough acceleration
and force over a period of six seconds. Once the shaking threshold is met, the
device outputs a message on the liquid crystal display (LCD) telling the user
that the inhaler is “ready to use.” With each compression of the inhaler, a
button is triggered on the inside of the InhaleSur case. This button allows the
device to keep track of the number of inhaler uses remaining before a
medication refill is needed. The number of “uses remaining” is printed on the
LCD screen. If the inhaler has zero uses remaining, an additional message is
printed on the LCD screen saying “refill required.” InhaleSur is easy to use, provides key
feedback to the user, and guarantees an adequately mixed dosage of medication.
