An injector comprises a cylindrical barrel including a discharge port, a seal body coming into close contact with an inner circumferential surface of the barrel, a plunger for pushing and moving the seal body to the discharge port side of the barrel, and a stopper disposed on one of the barrel and the plunger and coming into elastic contact with the other in a radial direction of the barrel.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.

A syringe comprising: a body delimiting a chamber; a piston able to slide in the chamber of the body along a longitudinal axis of the syringe, wherein the piston comprises a rod, a head, and a finger rest, which are all in one piece; and a deformable retention device designed to prevent the piston from leaving the body entirely, wherein the retention device is force-fitted in the chamber, extends around the piston over an angular sector strictly greater than 180° when it is in the assembled position, and has protruding external ribs which extend parallel to the longitudinal axis and are plastically deformable when the retention device is assembled in the chamber.

A single use syringe is disclosed that can be manufactured with minimal time and expense. The barrel is, in one example, compressive thermoformed by extruded tubing and with a resilient wall. The plunger can also be thermoformed. A fluid seal can be established between the resilient barrel sidewall and a rigid plunger sealing ring. The open, proximal end of the barrel is thermally flanged to maintain the barrel's configuration and provide a flange for gripping. The syringe can have non-circular cross sectional shapes, multiple lumens and multiple indentations to provide for a wide range of specific uses.

A syringe is described with a plunger assembly that is adapted to have a dispensing stroke sized to dispense a fluid therapeutic product from the syringe without dispensing any air or headspace. The syringe includes a plunger rod having a stop feature that stops a dispensing stroke of the plunger rod at a distance corresponding to a level of air or headspace within the syringe avoiding additional air dispensing steps from a healthcare provider.

The present disclosure relates to a medical delivery device that includes a barrel having an inner surface, a plunger rod having a distal end inserted within the barrel, and a stopper attached to the distal end of the plunger rod and contacting at least a portion of the inner surface of the barrel. In at least one embodiment, the inner surface is hydrophilic. The stopper may include an elastomeric body, one or more fluoropolymer layers, and two or more ribs laminated with the one or more fluoropolymer layers. In some embodiments, the contact width between at least one rib having a sealing surface and the portion of the inner surface of the barrel measured at a compressibility of greater than about 7.9% of the stopper is less than about 1.0 mm.
