    摘要： A connector mountable to a syringe barrel has a proximal barrel-engaging portion, a distal luer fitment portion, and a fluid aperture therethrough. The barrel-engaging portion of the connector includes an axial ledge configured to abut the axial distal edge of a glass syringe barrel. The connector facilitates mounting a luer assembly to the barrel. The luer assembly may be a tip cap having a complementary luer fitment for connection to the luer fitment portion of the connector. The luer assembly may be a luer needle assembly having a complementary luer fitment for connection to the luer fitment portion of the connector. The connector and syringe may further include an immobile, compressible needle seal. The needle seal is adjacent to or engageable with the barrel-engaging portion of the connector. The syringe may be configured with a plunger capable of engaging a retractable needle.

    摘要： A replaceable needle assembly is provided for a retractable, prefilled syringe comprising a barrel having a mounting member and a plunger, whereby the retractable needle can be replaced by a user without affecting the retraction mechanism. The replaceable needle assembly comprises a needle fitted to a retractable needle mount and a needle retainer. The needle mount is removably, screw-threadedly mountable to the mounting member of the barrel. The needle retainer comprises a plurality of fingers that releasably engage the retractable needle to thereby prevent inadvertent retraction of the retractable needle before engagement by the plunger. The plunger comprises a plunger seal comprising an outer member and an inner member that engages the needle for spring-driven retraction. At the end of retraction, a lock is formed between the plunger and barrel to prevent re-use of the syringe.

    摘要： A safety syringe has a barrel, a pushing element, a retracting element, and a needle group. The barrel is hollow and has a needle-group mounting end, an operating grip end, and a barrel lumen. The pushing element is retractably mounted in the barrel lumen and has a pushrod chamber. The retracting element is airtightly and slidably mounted in the pushrod chamber. The needle group is connected to the needle-group mounting end of the barrel. The present invention can pull the retracting element to move relative to the pushing element to form a low pressure condition in the pushrod chamber as a vacuum status. After the injection, a vacuum attraction force in the pushrod chamber can retract the used needle group into the pushrod chamber for safe use of the safety syringe.

    摘要： A retractable safety syringe may have a ferrule and needle which are selectively removeable from a distal end of a syringe body. In particular, the ferrule may have an annular flange. A wedge element may be frictionally engaged to the ferrule and a distal end of the syringe body. To retract the needle into the syringe body, a punch of a piston displaces the wedge element off of an annular flange of the ferrule. At about the same time, longitudinally offset tabs engage an annular flange and retract the needle into the syringe body via a retraction force created by a variable vacuum compartment or tension member.Alternatively, the ferrule and needle may be temporarily fixed to the distal end of the syringe body via a detent and/or o-ring which engages a lower undercut groove and an upper undercut groove of the ferrule. An annular ring of the piston may have longitudinal offset tabs which engage an annular ring of the ferrule. Upon engagement, the retraction force of the variable vacuum compartment is sufficient to overcome any retaining forces created by the detent and/or the o-ring. Thereby, the needle and ferrule may be retracted into the syringe body.The longitudinal offset tabs may cant the needle when the needle is retracted into the syringe body.

    摘要翻译： 可伸缩的安全注射器可以具有可从注射器主体的远端选择性地移除的套圈和针头。 特别地，套圈可以具有环形凸缘。 楔形元件可以摩擦地接合到套圈和注射器主体的远端。 为了将针缩回到注射器主体中，活塞冲头将楔形元件从套圈的环形凸缘移开。 大约在同一时间，纵向偏移突出部接合环形凸缘，并且经由可变真空隔室或张力构件产生的缩回力将针头缩回注射器主体。 或者，套圈和针可以经由与套圈的下底切槽和下凹槽啮合的止动器和/或O形环临时固定到注射器主体的远端。 活塞的环形环可以具有接合套圈的环形环的纵向偏移突片。 在接合时，可变真空室的缩回力足以克服由止动器和/或O形环产生的任何保持力。 因此，针和套圈可以缩回到注射器主体中。 当针缩回注射器主体时，纵向偏移突片可能会使针头倾斜。

    摘要： A syringe is provided. A front end of a barrel has an annular blocking portion which has at least two projections and at least two engaging slots defined by the projections, and one side of each projection has a guiding face. A connector which has at least two blocking members arranged circumferentially is assembled to the front end of the barrel, and one side of each blocking member has an incline. The blocking members are respectively received in the engaging slots and blocked by the projections. A plunger is movably received in the barrel, wherein a front end thereof is movable and abuttable correspondingly against the bottom of the connector, and the front end of the plunger is connected with the bottom of the connector.
