The incoming device (1) accommodates the medicine of the plural time dosages which it should you weigh distribute from there, or, it is possible to accept. In order to improve the problem of duplication dosage from the inhalator (1), the incoming device, furthermore, the obstruction expedient which obstructs the fact that you weigh distribute the medicine of time dosage at least temporarily (26, 28 and 40) with, the detection expedient which detects the inhalation of the medicine of the dosage amount which first it is weighed is distributed (32) with includes. When detection expedient (32) detecting the inhalation of the medicine of the dosage amount which first it is weighed is distributed, detection expedient (32), obstruction expedient (26, 28 and 40) it releases, you make weigh makes the medicine of further dosage amount the device distribute. Detection expedient (32), it is possible to be the pressure sensor, obstruction expedient (26, 28 and 40), by making the release of operation mechanism cause to operate it is possible.< Selective figure >Figure 5吸入装置(1)は、そこから計量分配されるべき複数回投与分の薬剤を収容するか、または、受け入れることができる。吸入器(1)からの二重投与の問題を改善するために、吸入装置は、さらに、回投与分の薬剤を計量分配することを少なくとも一時的に阻止する阻止手段(26、28、40)と、先に計量分配された投与分の薬剤の吸入を検出する検出手段(32)とを含む。検出手段(32)が先に計量分配された投与分の薬剤の吸入を検出したとき、検出手段(32)は、阻止手段(26、28、40)を解放し、装置にさらなる投与分の薬剤を計量分配させる。検出手段(32)は、圧力センサであってもよく、阻止手段(26、28、40)は、作動機構の解放を生じさせることによって作動させてもよい。【選択図】図5
