    • In a drug delivery device a dose to be apportioned from a cartridge is set by changing the relative position of co-operating dose setting elements (3, 5) and is injected by pressing a button (5) until this button abuts a stop (6). By operation of count up (7) or count down (8) buttons the dose is set and read into an electronic circuit (9) comprising a microprocessor and the dose setting movement of the dose setting elements relative to each other is performed by a motor (11) controlled by the circuit in accordance with the read in dose. The set dose is shown on a display (10). The motor (11) is further controlled to perform certain movements of the piston rod (3) so as retraction of this rod when a cartridge (1) is going to be changed an advancing of the piston rod to abutment with the piston (2) after the cartridge has been changed and further to advance this piston to expel air from the cartridge.
    • 在药物输送装置中,通过改变配合剂量设定元件(3,5)的相对位置来设定从药筒分配的剂量,并且通过按压按钮(5)来注射直到该按钮抵靠止动件(6) )。 通过计数(7)或倒计时(8)按钮的操作,剂量被设置并读入包括微处理器的电子电路(9),并且剂量设定元件相对于彼此的剂量设定运动由电动机 (11)由电路按照读取剂量控制。 设定的剂量显示在显示器(10)上。 电动机(11)被进一步控制以执行活塞杆(3)的某些运动,以便当筒(1)将改变活塞杆的前进以与活塞(2)邻接时,该杆的缩回, 在盒被改变之后,并且进一步推进该活塞以从盒中排出空气。
