Abstract: A method for preparing a pre-filled multi-chamber injection system includes providing an injection system body, the injection system body defining an open proximal end, a body interior, and an open distal end. The method also includes introducing a first substance into a distal end of the body interior. The method further includes disposing a distal stopper member in the body interior, the distal stopper member and the injection system body defining proximal and distal chambers in the body interior. Moreover, the method includes introducing a second substance into the body interior. In addition, the method includes disposing a proximal stopper member in the body interior. The method also includes inserting an elongate member at least partially into the body interior, the elongate member having a plurality of flow channels for fluidly coupling the proximal and distal chambers. The method further includes coupling a plunger member to the proximal stopper member.

Abstract: A system for injecting includes a syringe body, a syringe interior, a syringe flange, and a stopper member and an injectable fluid disposed in the syringe interior. The system also includes a plunger member coupled to the stopper member. The system further includes a finger flange removably coupled to the syringe flange, the finger flange defining a pair of side openings and a pair of bumps adjacent respective side openings. Moreover, the system also includes a swing spacer rotatably coupled to the finger flange, the swing spacer defining a pair of arms, a pair of pivot pins, two pairs of slots, and a pair of indentations. The swing spacer is configured to define a distance of movement of the plunger member relative to the syringe body along a longitudinal axis of the syringe body, thereby defining a dose of the injectable fluid.

Abstract: A system for serially injecting liquids includes a syringe body defining a syringe proximal opening and a distal needle interface, proximal and distal stopper members, forming proximal and distal chambers. The system also includes a first liquid in the distal chamber and a second liquid in the proximal chamber, and a plunger configured to be manually manipulated to insert the proximal stopper member distally. Moreover, the system includes a needle hub assembly coupled to the syringe body, the needle assembly including a needle. The needle defines a needle interior, and distal, middle and proximal openings. The distal, middle and proximal openings are fluidly coupled through the needle interior. Manipulating the plunger member to insert the proximal stopper member initially expels the first liquid from the distal chamber, then serially expels the second liquid from the proximal chamber.

Abstract: A system for injecting includes a syringe 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 syringe body, the plunger member. 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 at least partially retractable into plunger interior. The needle proximal end feature includes an annular distally facing surface.

Abstract: An injection system includes a molded body member having a body connection member at a distal end thereof. The system also includes a needle hub assembly coupled to the distal end of the injection system body. The needle hub assembly includes a needle hub coupled to the body connection member, a needle coupled to the needle hub, and a barbed band disposed around a proximal end of the needle hub and having a barb. The barbed band allows rotation of the needle hub assembly relative to the body connection member in a first direction, while preventing rotation of the needle hub assembly relative to the body connection member in a second direction.
