摘要： An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end including a distal wall with an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with the chamber. A plunger having an elongate body portion and a stopper slidably positioned in fluid-tight engagement with the inside surface of the barrel is provided. Anti-reflux structure in said barrel is provided for controlling stopper deflection when fluid has been delivered from the chamber and the stopper is in contact with structure on the distal wall.

摘要： A stopper adapted for attachment with a plunger rod for use within a syringe barrel is disclosed. The stopper includes a main body defining an open rearward end and a closed front end. The open rearward end is adapted to receive a front forward end attachment portion of the plunger rod. The stopper also includes a core member integrally formed with the main body adjacent the closed front end. The core member includes a nose portion having a conical tip configured for entering an outlet opening of the syringe barrel. The closed front end of the stopper has a profile configured to cooperate with an internal surface of the syringe barrel wall to prevent reflux and reduce dead space within the barrel.

摘要： A syringe assembly includes a syringe barrel having an exterior surface, an inside surface defining a chamber, an open proximal end, a distal end, and an outlet disposed adjacent the distal end in fluid communication with the chamber; and a plunger assembly disposed at least partially within the syringe barrel. The plunger assembly includes an elongated plunger rod and a plunger head. The elongated plunger rod is associated with the plunger head to move the plunger head within the chamber of the syringe barrel through an injection cycle. The plunger rod is adapted to move from a collapsed position extending alongside the exterior surface of the syringe barrel to an extended position engaging the plunger head to move the plunger head through the injection cycle.

摘要： A plunger rod adapted for attachment with a stopper for use with a syringe barrel is disclosed. The plunger rod includes an elongated member having a front end and a back end, the plunger rod extending along a longitudinal axis. The plunger rod includes at least one deflecting arm associated with the front end of the elongated member. The deflecting arm is capable of deflecting radially inward during insertion of the plunger rod into a stopper, and deflecting outward into contact with an inner surface of the stopper after insertion to lock the plunger rod within the stopper.

摘要： A medical device for delivering a medicament to a patient. The device includes a syringe barrel assembly having a syringe barrel with a plunger movably insertable therein to expel medicament in the barrel. A needle cannula is connected to a needle cannula hub which is slidably arranged in the barrel for moving between an initial position in which the forward tip is exposed and a retracted position in which the forward tip is contained within the barrel. A retainer engages an annular groove defined in an inner surface of the barrel and secures the needle cannula hub at the initial position proximate the front end of the barrel. An urging member is arranged between the front end of the barrel and the needle cannula hub for urging the needle cannula hub toward the retracted position. The retainer is released in response to the application of medicament delivery force when the stopper is in a fully inserted position.

摘要： A flange extender for use with an injection device is described. The flange extender includes first and second flange extender pieces and a locking mechanism to lock the first and second flange extender pieces to one another. In one embodiment, the locking mechanism includes each piece having a locking finger extending from the piece and an aperture adapted to receive the locking finger. The first and second flange extender pieces extend in a direction transverse to a main axis of the injection device to thereby provide a surface area for manual manipulation of the injection device during an injection. The first and second flange extender pieces also attach to each other on opposite sides of the injection device.
