    Abstract: An injection system includes a syringe body defining a proximal opening at a proximal end thereof and a distal needle interface at a distal end thereof. The system also includes proximal and distal stopper members disposed in the syringe body, forming respective proximal and distal drug chambers. The system further includes a plunger member configured to be manually manipulated to insert the proximal stopper member relative to the syringe body. Moreover, the system includes a fluid conveying assembly including a penetrating member configured to penetrate the distal stopper member to fluidly couple the proximal and distal drug chambers, a distal exit tube, and a transfer member disposed at least partially around a portion of the penetrating member and defining a fluid passage. A distal end of the penetrating member is disposed in the distal exit tube.

    Abstract: A system for serially injecting liquids includes a syringe body, proximal and distal stopper members disposed in the syringe body, a first liquid in a distal chamber, a second liquid in a proximal chamber, a plunger member, and a needle hub assembly coupled to a distal needle interface of the syringe body. The plunger member includes a needle retention feature disposed in a plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. 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. Manipulating the plunger member to insert the proximal stopper member distally relative to the syringe body initially expels the first liquid, then the second liquid. The needle is at least partially retractable into plunger interior.

    Abstract: A syringe assembly includes a syringe body, needle assembly, retaining clip, gasket, needle latch, and needle hub. The syringe body has a syringe interior, longitudinal axis, proximal and distal ends, and needle attachment interface disposed at the distal end thereof. The gasket is configured to be compressed to provide a liquid-tight seal around an outer diameter of the needle assembly and the distal end of the syringe body. The needle latch assembly includes first and second latching tabs configured to retain the needle assembly in a close state and to be plastically deformed to an open state to release the needle assembly, and a gasket backstop configured to provide a flat surface for compression of the gasket, where the first and second latching tabs are spaced apart from the gasket such that neither of the first and second latching tabs contact the gasket during compression of the gasket.

    Abstract: A system for injecting 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. The plunger member includes a rotatable member configured to insert the stopper member distally in the syringe interior relative to the syringe body with rotation of the rotatable member. The plunger member further includes a proximal portion proximal of the rotatable member configured to be moved distally to also insert the stopper member distally in the syringe interior relative to the syringe body to eject about microliters of fluid from the syringe interior.

    Abstract: One embodiment is directed to a system for injecting, comprising a syringe body defining an interior medicine chamber; a stopper member configured to be inserted into the interior medicine chamber to contain medicine within the medicine chamber; a plunger member configured to be manually manipulated to insert the stopper member relative to the syringe body; a needle having proximal and distal ends, the proximal end comprising an anchoring geometry configured to be at least partially penetrated into the stopper member such that upon retraction of the stopper member, the needle is pulled proximally along with the stopper to be at least partially contained within the interior medicine chamber; and an energy-storing member operatively coupled between the stopper member and the syringe body, the energy-storing member configured to facilitate retraction of the stopper member relative to the syringe body.

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 syringe 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 syringe 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: 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.
