    • A breath powered dry powder inhaler configured to deliver particles to the pulmonary circulation of a subject comprises a chamber for containing the particles and a mouthpiece. Portions of the inhaler define a flow path leading from at least one inlet (119) to said chamber through said chamber and through at least one outlet (127) from said chamber to the mouthpiece. The at least one inlet and the at least one outlet are further configured so that air from the at least one inlet is directed across said at least one outlet and controls exit from the chamber of powder entrained within the flow. In embodiments the at least one inlet (119), the at least one outlet (127) and the chamber are configured so that in use air entering the chamber circulates within the chamber for promoting entrainment and lifting of a powder in the chamber. In these embodiments the inlet may define a first direction for air entry into the chamber, the outlet may define a second direction generally perpendicular to the first direction for air and powder leaving the chamber, and the inlet (119), outlet (127) and chamber may be configured so that in use air within the chamber circulates about an axis directed generally perpendicular to the first and generally perpendicular to the second direction. The chamber may contain a cohesive powder e.g. a diketopiperazine, and the powder may contain insulin or another medicament.
    • 构造成将颗粒递送至受试者的肺循环的呼吸动力干粉吸入器包括用于容纳颗粒和吸口的腔室。 吸入器的部分限定了从至少一个入口(119)通过所述腔室通过所述腔室并且通过至少一个出口(127)从所述腔室到达吹口的流动路径。 所述至少一个入口和所述至少一个出口进一步构造成使得来自所述至少一个入口的空气被引导穿过所述至少一个出口并且控制从所述流动内夹带的粉末室的出口。 在实施例中,至少一个入口(119),至少一个出口(127)和腔室被构造成使得在使用中进入腔室的空气在腔室内循环以促进腔室中粉末的夹带和提升。 在这些实施例中,入口可限定空气进入腔室的第一方向,出口可限定大致垂直于第一方向的第二方向,以使空气和粉末离开腔室,并且入口(119),出口(127)和 腔室可构造成使得在使用中腔室内的空气围绕大致垂直于第一方向且大致垂直于第二方向的轴线循环。 该室可以含有粘结粉末,例如, 二酮哌嗪,粉末可以含有胰岛素或其他药物。
