摘要：
A retractable syringe (11) and plunger (20) therefore are provided, whereby the plunger comprises a controlling means (62) which facilitates control of the rate of retraction of the retractable needle. By controlling the rate of needle retraction, the likelihood of blood spattering is reduced thereby improving the user-friendliness and appeal of the retractable syringe. Typically, the syringe is a prefilled syringe. Following plunger depression, a symmetrical ejector member (92) releases the retractable needle (40) from a retaining member (30) to thereby allow retraction of the retractable needle. Needle retraction is facilitated by a biasing means (70), such as a spring or other compressible and/or de-compressible device. The plunger comprises a plunger housing (21), in which is located the controlling means. The controlling means may be pneumatic air space (324) inside the plunger housing which automatically acts against the retracting needle to thereby control or regulate the rate of retraction.
摘要（中）：
因此，提供可伸缩注射器（11）和柱塞（20），由此柱塞包括控制装置（62），其有助于控制可缩回针的缩回速率。 通过控制针回缩的速度，血液溅射的可能性降低，从而改善了可伸缩注射器的用户友好性和吸引力。 通常，注射器是预充式注射器。 在柱塞下压之后，对称的顶出件（92）将可伸缩针（40）从保持件（30）释放，从而允许可缩回的针头缩回。 通过诸如弹簧或其它可压缩和/或不可压缩装置的偏置装置（70）来促进针回缩。 柱塞包括柱塞壳体（21），其中位于控制装置中。 控制装置可以是柱塞壳体内部的气动空气空间（324），其自动地作用在回缩针上，从而控制或调节回缩速率。
