    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 dose control mechanism for a syringe includes an engaging screw thread arrangement between an exterior surface of a plunger and a longitudinally extending channel of a housing. The engaging screw thread arrangement includes at least one thread segment and a pitch guide including a variable pitch thread. At least a portion of the longitudinally extending channel of the housing including one of the pitch guide and the at least one thread segment, and the plunger includes the other of the pitch guide and the at least one thread segment. The plunger resides at least partially within the housing with the at least one thread segment engaged with the pitch guide. An accurate dose drug delivery syringe includes such a dose control mechanism, a barrel, a plunger seal, and a barrel adapter assembly having a barrel tip and a needle. The syringe may be a fill-at-time-of-use syringe, a pre-filled syringe, or a safety syringe having integrated needle retraction or needle sheathing safety features, or a combination thereof. Methods of assembly, manufacturing, and operation are similarly disclosed.

    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: Mixing syringes including a valve mechanism are configured and configurable to enable one or more substances to be prefilled into the syringe. The valve mechanism may be an aspect of a distal seal assembly. Actuation of the valve mechanism permits opening of a fluid passage for the mixing of one or more substances, and the resulting mixed substance can be delivered by the syringe, for example, for administration of a pharmaceutical to a subject. The repetitive mixing of substances contained in a distal and proximal chamber is also provided, where the plunger rod is configured to releasably engage a locking mechanism to actuate the valve, and can axially displace the distal seal assembly while the fluid passage is open.
