Abstract: An assembly for mixing drug components includes a housing to at least partially hold a first drug component container and a second drug component container. The assembly also includes a transfer member having first and second ends to fluidly couple the respective first and second drug component containers. The assembly further includes a pressure member to fluidly couple the first drug component container to a pressure generation chamber. In addition, the assembly includes an energy storage member to generate pressure in the pressure generation chamber to transfer a fluid from the first drug component container into the second drug component container. Moreover, the assembly includes an exit member to fluidly couple the second drug component container to an exterior of the assembly.

Abstract: A system for measuring injection of a liquid medicine includes a syringe body having proximal and distal ends, a syringe interior, and a syringe flange at the proximal end thereof. The system also includes a stopper member disposed in the syringe interior. The system further includes a plunger member coupled to the stopper member and configured to be manipulated to insert the stopper member distally in the syringe interior relative to the syringe body. Moreover, the system includes a needle coupled to the syringe body at the distal end thereof. In addition, the system includes a sensor flange removably coupled to a syringe body. The sensor flange includes a sensor to measure an injection characteristic and a processor to analyze the injection characteristic to determine an occurrence of an injection event.

Abstract: A system for mixing drug products and injecting includes a syringe body, proximal and distal stopper members disposed in the syringe body, a plunger member, and a needle hub assembly coupled to the distal needle interface of the syringe body. The proximal and distal stopper members form a proximal drug chamber between there between and a distal drug chamber between the distal stopper member and a distal end of the syringe body. The plunger member includes a needle retention feature, an energy-storage member, and an energy-storage member latching member all disposed in disposed in a plunger interior. First and second sizes of the respective proximal and distal drug chambers can be modified by movement of the proximal and distal stopper members relative to the syringe body. The needle is at least partially retractable into plunger interior upon manipulation of the plunger member relative to the syringe body.

Abstract: A system for injecting includes a cartridge body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the cartridge body. The plunger member includes a needle retention feature disposed in the plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The system further includes a needle hub assembly coupled to the distal needle interface of the cartridge body. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. The needle is retractable into plunger interior upon manipulation of the plunger member to actuate the energy-storage member latching member.

Abstract: One embodiment is directed to a pre-filled safety syringe system, comprising a syringe body; a plunger tip positioned within the syringe body; a needle assembly removably coupleable to the distal end of the syringe body such that a medicinal fluid may be transferred through a retractable needle coupled to a needle housing comprising the needle assembly upon insertion of the plunger tip relative to the syringe body; and a plunger control assembly coupled to the plunger tip and configured to facilitate manual insertion of the plunger tip relative to the syringe body; wherein upon insertion and release of the plunger tip, a retraction load coupled between the syringe body and the plunger tip causes the plunger tip to be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state.
