    • This invention concerns a disposable single dose syringe type applicator in the form of an elongated body that comprises two integrally joined sections which can be separated by breaking. One section is a tubular barrel section which constitutes a medicament reservoir having two openings. The other section is a rod-like section, which constitutes a plunger, which, by reason of being integrally joined to the barrel section seals one opening of the reservoir. The reservoir section is prefilled with a medicament. At the other opening end of the medicament reservoir, through which it is prefilled with medicament, there is arranged an easily removable sealing means. After separation, the plunger section slidably fits into the reservoir in such a way that essentially the whole medicament content of the reservoir is ejected therefrom when the plunger is inserted into the reservoir.
    • 本发明涉及一种细长体形式的一次性单剂量注射器型施用器,其包括两个可通过断裂分离的整体接合部分。 一个部分是管状的桶形部分,其构成具有两个开口的药物储存器。 另一部分是杆状部分,其构成柱塞,由于与筒部一体地连接,密封储存器的一个开口。 储存器部分预填充药物。 在药剂储存器的另一开口端,通过该药剂储存器预填充药物,布置有容易移除的密封装置。 分离后,柱塞部分以这样的方式可滑动地装配到储存器中:当柱塞插入储存器中时,基本上将储存器的整个药物内容物从其中喷出。
