Abstract: The invention provides a syringe for use in an ophthalmic injection. The syringe comprises a body, a stopper and a plunger. The body comprises an outlet at an outlet end and the stopper is arranged within the body such that a front surface of the stopper and the body define a variable volume chamber from which a fluid can be expelled though the outlet. The plunger comprises a plunger contact surface at a first end and a rod extends between the plunger contact surface and a rear portion. The plunger contact surface is arranged to contact the stopper but not couple thereto, such that the plunger can be used to force the stopper towards the outlet end of the body, reducing the volume of the variable volume chamber, but not to move the stopper away from the outlet end.

Abstract: A method for manufacturing a syringe is described. The syringe includes a barrel having an open proximal end, a piston shaft having proximal and distal ends, and a piston having a longitudinal axis and opposing proximal and distal axial ends. Initially, a partially formed piston body is molded. The piston is then completely molded. The distal end of the piston shaft is engaged with the proximal axial end of the piston. The piston engaged with the piston shaft is received in the open proximal end of the barrel.

Abstract: A device and method for measuring a volume of liquid expelled from a syringe is provided. The device generally includes a syringe barrel, a plunger actuated with a plunger rod, and a sensor. The sensor may include two ports with one port being in fluid communication with a source of fluid external to the syringe barrel, while the second port is in fluid communication either with a proximal end portion of the syringe barrel or a hollow plunger rod having a first end closed by the plunger. The method may include expelling liquid from the syringe; detecting and recording differential pressure with the sensor over time; and calculating the volume of liquid expelled from the syringe from the recorded differential pressure over time.

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: A dual chamber syringe facilitates selective drug mixing, dosing, and administration, as well as pre- or post-administration flushing with a single syringe instrument. A syringe barrel incorporates an outlet, as well as variable-volume, primary and secondary fluid chambers, separated by a floating stopper. The floating stopper defines a dome-shaped split septum with a central slit at its apex. The split septum is a bi-stable valve, closing the central slit by compression in its meridial dimension when the septum is in a first, relaxed state, and opening the central slit when the septum is buckled or flipped under tension in the meridial dimension in a second state. Buckling of the septum wall is caused solely by differential fluid pressure applied by a single plunger, without physical contact of the septum with any other structure within the syringe.

Abstract: The present disclosure relates to a syringe including a container, for containing a primary fluid, and at least one secondary fluid chamber configured to contain a secondary fluid. The container comprises a proximal end and a distal end and having a distal end opening at the distal end. The syringe further comprises a stopper, movably arranged within the container; and a plunger engageable with the stopper and configured to apply a force to the stopper to move the stopper within the container towards the distal end of the container, to expel primary fluid from the container through the distal end opening. The plunger is further configured to expel secondary fluid from the at least one secondary fluid chamber towards the distal end opening, to expel at least a portion of a residual volume of primary fluid through the distal end opening. A plunger system and assembly for a syringe and methods of expelling fluid from a syringe are also disclosed.
