    摘要: A dose tape for use in a dry powder inhaler has blisters formed in a formpack layer. A lidstock layer is permanently attached over the formpack layer, to seal a dose of dry powder within each of the blisters. A tear strip is attached to the lidstock layer over each of the blisters. The dose tape is provided in a coil within an inhaler having a breath actuated tape advance blister opening system. Moving a dustcap off of a mouthpiece into an open position places the tape advance/blister opening system into a ready condition. When the patient inhales on the mouthpiece, the tape advance/blister opening system is triggered. The blister or dose tape is advanced by one increment, and a blister is automatically opened. Pulling on the tear strip shears out an area of the lidstock over the blister, unsealing the powder contents. Airflow through an air path in the inhaler, generated by inhalation, carries the powder to a disbursion chamber, or directly to the mouthpiece, for inhalation by the patient.

    摘要: A dry powder inhaler includes an actuator pivotably mounted on a base. Movement of the actuator from a first position to a second position drives the a dobber to open a blister. A dispersion engine sub-assembly has a blister hood positioned over a blister opening position. A powder pathway connects from the blister hood into a powder dispersion engine. Upon inhalation, air flow draws powder up and out of an opened blister, into the blister hood and to the powder dispersion engine. Movement of the actuator causes the dobber to shear open a blister and also to press the blister hood down over the blister. This increases air flows up and around the open blister, carrying the pharmaceutical powder up and out of the blister and into the dispersion engine.
