    • PROBLEM TO BE SOLVED: To provide a medicine discharger capable of discharging an appropriate amount of medicine by performing stable discharge even when a highly sealed medicine tank is used.
      SOLUTION: A medicine storage part 2 for storing the medicine is connected to a medicine discharge part 1 composed of a discharge port 1a for discharging the medicine and an element 1b for generating energy to discharge the medicine from the discharge port 1a. Since the medicine storage part 2 is shielded from outer air except the discharge port 1a, a pressure difference is generated between the inside and outside of the medicine storage part 2 when the medicine is discharged from the discharge port 1a. A pressurizing means 3 which characterizes the present invention pressurizes a mobile wall 5 which is displaced to reduce the volume of the medicine storage part 2 by the pressure difference in the case of discharging the medicine.

    • 要解决的问题:提供一种即使在使用高度密封的药液罐的情况下也能够通过稳定的排出能够排出适量的药物的放药器。 解决方案:用于储存药物的药物储存部分2连接到由用于排出药物的排放口1a构成的药物排出部分1和用于产生能量以从排出口1a排出药物的元件1b。 由于药剂贮存部2与排出口1a以外的外部空气隔绝,所以当药物从排出口1a排出时,在药剂容纳部2的内外产生压力差。 特征在于本发明的加压装置3对移动壁5进行加压,该移动壁5在排出药物的情况下通过压力差而移位以减小药物储存部2的体积。 版权所有(C)2009,JPO&INPIT
