Patent number: 11058826Abstract: 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.Type: GrantFiled: January 10, 2019Date of Patent: July 13, 2021Assignee: UNL Holdings LLCInventors: Craig Stephen Thorley, Joseph Hermes Kaal, Christopher Charles Rafferty, Ian Johnson, Eric Siu, Andrew Reade

Patent number: 10166336Abstract: 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.Type: GrantFiled: July 11, 2014Date of Patent: January 1, 2019Assignee: UNL Holdings LLCInventors: Katlin M. Lumme, Philip A.
