    • An aspiration device (3) comprises a syringe barrel coupling element (50), for coupling to a barrel of a syringe (5), and a plunger coupling element (50), for coupling to a plunger of a syringe (8). The plunger coupling element (12) and the barrel coupling element (50) are moveable relative to each other by application of force to pressure portions (20, 60) associated with each element and the pressure portions (20, 60) are adapted to be forced towards each other by a user placing a finger tip (43) on a first pressure portion and a thumb tip (41) on a second pressure portion. Forcing the pressure portions (20, 60) towards each other forces the plunger (8) to move out of the barrel (5), effecting an aspiration mode.
    • 抽吸装置(3)包括用于联接到注射器(5)的筒的注射器筒联接元件(50)和用于联接到注射器(8)的柱塞的柱塞联接元件(50)。 柱塞联接元件(12)和筒体联接元件(50)可通过向与每个元件相关联的压力部分(20,60)施加力而相对于彼此移动,并且压力部分(20,60)适于 通过用户将指尖(43)放置在第二压力部分上的第一压力部分和拇指尖端(41)上而彼此强迫。 迫使压力部分(20,60)朝向彼此迫使柱塞(8)移出筒体(5),从而实现抽吸模式。
