    • 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 a pneumatic air space (324) inside the plunger housing which automatically acts against the retracting needle to thereby control or regulate the rate of retraction.
    • 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,从而提高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。

    • A retractable, single use syringe (10) comprises a barrel (20), a collar (60) mounted to the barrel, a retraction spring (70), a needle mount (40) located at a needle end (23) of the barrel and a plunger (30). The plunger comprises a first plunger member (31) and a second plunger member (33) that are releasably coupled to co-operatively maintain the retraction spring in an initial compressed state. The second plunger member (33) further comprises a seal (34) to prevent fluid leakage between plunger (30) and barrel (20). After depression of the plunger to deliver the fluid contents of the syringe, the first plunger member (31) engages the needle mount (40) with needle (12) attached thereto and is rotatably uncoupled from the second plunger member (33) to allow decompression of the retraction spring (70), which forces retraction of the first plunger member (31), needle mount (40) and needle (12) engaged therewith. The first plunger member (31) and the collar (60) comprise elements that co-operatively form a disabling means that prevents or at least minimizes the likelihood of subsequent depression or withdrawal of the plunger (30). Also following retraction of the first plunger member (31), the second plunger member (33) and seal (34) remains at the needle end (23) of the barrel (20) thereby preventing refilling and re-use of the syringe.
    • 一种可收回的一次性注射器(10)包括筒体(20),安装在筒体上的套环(60),缩回弹簧(70),位于筒体针端(23)处的针座(40) 和柱塞(30)。 柱塞包括第一柱塞构件(31)和第二柱塞构件(33),第一柱塞构件(31)和第二柱塞构件(33)可释放地联接以将缩回弹簧共同维持在初始压缩状态。 第二柱塞构件(33)还包括密封件(34),以防止柱塞(30)和筒体(20)之间的流体泄漏。 在按压柱塞以输送注射器的流体内容物之后,第一柱塞构件(31)与针安装件(40)接合,针头(12)附接到其上并且可转动地与第二柱塞构件(33)脱开以允许减压 的缩回弹簧(70),其迫使第一柱塞构件(31),针座(40)和与其接合的针(12)的缩回。 第一柱塞构件(31)和套环(60)包括可同时形成禁用装置的元件,其阻止或至少最小化后续的压下或抽出柱塞(30)的可能性。 此外,在第一柱塞构件(31)的缩回之后,第二柱塞构件(33)和密封件(34)保留在筒体(20)的针端(23)处,由此防止注射器的再填充和再次使用。
