Abstract
A dry powder inhalant device adapted for mounting on a conventional medication dry powder dispenser having a mouthpiece incorporated in one end of the dispenser. The device designed for monitoring prescribed dosages of dry powder medication received through the mouthpiece, the lips and into the mouth, throat, and respiratory system of a user of the device. The device includes an electronic housing mounted on the dispenser for computing and recording when a proper amount of dry powder is released inside the dispenser, when a proper amount of air flow is inhaled through the dispenser for mixing with the dry powder, and when each dispenser or dry powder container is removed and replaced on the electronic housing. The dispenser, in one embodiment, includes an activation sheath received around and secured to a portion of the dispenser. A lower end of the sheath abuts the electronic housing with the mouthpiece extending upwardly and through an upper end of the sheath. The electronic housing includes a first and second proximity reed switch for recording when a proper dosage of dry powder is released inside the dispenser by properly rotating the sheath and dispenser a fixed distance in one direction on the electronic housing and rotating the sheath and dispenser a fixed distance in an opposite direction. The electronic housing also includes a fast response thermistor for measuring when sufficient air flow is being drawn into the housing, into the dispenser and mixed with the dry powder and out the mouthpiece when using the device.
