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.

Vaccination syringe

A vial adapter is provided for interconnecting a vial having a closure and a fluid delivery device such as a safety syringe. The vial adapter comprises an adapter housing having a base, a shroud extending or projecting from the base and a cannula extending or projecting from the base for penetrating a rubber seal on the vial closure to thereby establish fluid communication between the vial and the vial adapter. The shroud may comprise a plurality of latitudinal slits or windows within each of which resides a flexion arm connected to the shroud, each flexion arm capable of engaging and/or retaining vial closures of any of a variety of different sizes. The vial adapter may comprise a conduit tip in fluid communication with the cannula to allow transfer of fluid to or from the safety syringe while also preventing inadvertent activation of a safety syringe needle retraction mechanism.

Vial adapters

An actuation mechanism for an automatic injector includes a first actuation spring, a first actuation pill, a second actuation spring, and a second actuation pill. In an initial configuration the first actuation spring resides in a compressed, energized state substantially within an upper portion of first actuation pill and the second actuation spring resides in a compressed, energized state between the first actuation pill and the second actuation pill. An automatic injector includes a housing, an activation mechanism, an actuation mechanism, and a syringe cartridge having a plunger and a needle assembly. A retractable syringe may be utilized as a syringe cartridge, such as a prefilled retractable syringe with integrated safety features which retract the needle after use. The automatic injector may be utilized to inject the needle, deliver a drug treatment, and activate retraction of the needle. Methods of assembly and operation are also provided.

Auto-injector for retractable prefilled syringe

A retractable needle is provided for a syringe comprising a barrel and a plunger that comprises a portion capable of engaging the retractable needle for retraction. The retractable needle comprises a cannula, a needle body having a plunger-engaging member, at least one aperture and an elongate portion which houses the cannula, the cannula comprising an end which is in fluid communication with the at least one aperture, wherein the at least one aperture is located between the plunger-engaging member and the elongate portion. The positioning of the at least one aperture distal to the plunger-engaging member maximizes the efficiency of fluid delivery.

Retractable syringe needle

An adapter mountable to a retractable syringe barrel comprises a body that includes a needle portion and a barrel-engaging portion and a needle aperture. The adapter facilitates mounting a needle assembly to the barrel. The needle assembly comprises a needle body and cannula and an immobile, compressible needle seal, wherein the needle body and the needle seal are releasably engaged. The needle seal is engageable with a needle portion of the adapter. The needle body comprises one or more fluid reclaim channels that facilitate efficient delivery of the fluid contents of the retractable syringe. The retractable syringe also comprises dual locking systems to impede or prevent re-use.

Syringe barrel adapter and needle assembly

The invention resides in an alignment device able to align substantially vertical starter bars for a masonry block wall, the alignment device comprising a plurality of spacer arms spaced a predetermined distance from each other and a plurality of attachment members attached to respective spacer arms, the attachment members able to be operatively attached to the vertical starter bars.

Alignment device

A block wall system including a block wall having a multiplicity of courses of blocks; at least one longitudinal reinforcement bar that extends through the block wall; and at least one bracket for locating the longitudinal reinforcement bar; wherein the longitudinal reinforcement bar passes through the void of at least one block in the block wall and through a capture zone of the bracket located within the block wall.
