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 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: One embodiment is directed to a safety syringe system, comprising: an off-the-shelf syringe assembly comprising a syringe body and a plunger tip; a needle assembly removably coupleable to the distal end of the syringe body such that 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 of the plunger tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.

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 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: 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.
