    • The invention concerns a multi-component syringe with a glass barrel (10) and suitable for use as a pre-filled unit. On the outside of the glass barrel (10) is a gripping plate (12). At the other end of the barrel from the gripping plate is a cap (20) with an adapter (23) for medical needles. The needle adapter (23) is sealed off by a closure element (24). At the other end of the barrel chamber from the cap (20) is a stopper (30). The cap (20) surrounds a glass element (22) which is attached to the cylindrical glass barrel (10) by means of an integral cap adapter, the glass element (22) forming part of the cap (20). In addition, a spring element (41) is located between the stopper (30) and the end-stop at the plunger-rod end of the barrel. The use of glass as the material for the syringe barrel ensures a low-distortion, gastight construction which is resistant to sterilization. The spring element (41) enables the stopper (30) to give when the contents of the syringe expand on warming, thus avoiding any risk of the syringe barrel (10) bursting.
    • 本发明涉及一种适用于具有一个玻璃筒(10)的预填充多部分注射器的形式。 玻璃圆筒(10)具有在外侧气缸把手板(12)。 气缸把持板相对是具有用于医用针的套管适配器(23)的盖(20)。 插管适配器(23)由接合器封闭元件(24)关闭。 盖(20)位于一个插头(30)的对面。 盖(20)包括其上固定有一个整体形成的帽适配器到圆柱形管玻璃的玻璃圆筒(10)的,其中,所述玻璃元件(22)形成所述帽(20)的一部分的玻璃元件(22)。 此外,位于所述插头(30)和玻璃圆筒内轴环布置的弹簧元件(41)的杆端部之间。 玻璃是一种材料允许气密和低失真的设计。 后者是不敏感的灭菌过程。 弹簧元件(41)允许所述填充的热膨胀过程中的插塞(30)的缩回,而不玻璃圆筒(10)的破裂的风险。
