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 said main body adjacent the closed front end. The core member includes a nose portion having a profile adapted to create a positive seal with an outlet opening of such syringe barrel.

A syringe tip for a syringe and the like in which the bore of the tip tapers so as to increase in diameter from the end of the tip adjacent the barrel of a syringe towards the distal end of the tip; and the outside diameter of said tip tapers so as to decrease in diameter from the proximal end of the tip (adjacent the barrel of said syringe) towards the distal end of the tip.

An arcuate guide projection is provided on a front surface of a flange of a syringe barrel and an arcuate guide groove for guiding the guide projection is provided on a front sidewall surface of a flange insert groove of a cylinder holder. When the syringe is mounted, the guide projection and the guide groove are brought into engagement thereby preventing the flange from slipping off upwardly.

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.

The micro-bolus feeder kit for infants includes at least one syringe and at least one adapter fitting for connecting a nipple ring (or nipple collar) and a nipple to the syringe so that the syringe may be used to deliver metered amounts of milk, formula, or other liquid nutrition to the infant. The syringe is preferably a 3 mL to 5 mL syringe with a plunger and graduated markings to show the volume of liquid in the syringe, and is capable of delivering the liquid in one-tenth to two-tenths milliliter increments. The adapter fitting is an annular disk adapted for gripping the tubular syringe barrel by friction or pressure fit, or resiliently, and has external threads on its periphery dimensioned and configured for receiving a nipple ring in order to attach a nipple to the delivery end of the syringe.

An aspiration and injection device is provided that can allow for ergonomic, safe, and precise aspiration of a target site and ejection of a medicament to the target site. The device can include a syringe barrel, a flange extender couplable to the barrel, and plunger that can be engaged by a hand and / or one or more finger of a user to perform aspiration and injection at a target site.

Methods and apparatus are disclosed for disposing a valve within a barrel of a conventional syringe to provide, first, a mixing syringe embodiment and, second, a sequential delivery syringe embodiment. Generally, the valve divides the syringe barrel into a proximal and a distal chamber. When used for mixing, the valve is self-displaceable by expansion of decompressing matter disposed within the valve against exterior matter permitting proximal displacement of the valve independent of character of matter in the distal chamber. For sequential delivery, switching of the valve occurs after switch opening causing pressure is relieved, thereby reducing inadvertent uncontrolled flow when the valve opens. In addition, a combination mixing and flush syringe is disclosed whereby a mixing and a flush capability is provided within a conventional syringe.

A gasket (10) is used for a medical syringe (30), and includes a main body (11) made of an elastic material and an inert resin film (12) provided on a surface of the main body (11). The gasket (10) has a cylindrical shape, and includes a plurality of annular ribs (13, 14, 15) provided on an outer circumferential surface (20) thereof and each having a sliding contact portion (16) to be kept in sliding contact with an inner peripheral surface of a syringe barrel. The plurality of annular ribs are axially arranged from a distal end to a rear end of the gasket (10). The sliding contact portion (16) of a distal annular rib (13) has a width that is 1 to 25% of axial length of the cylindrical gasket.

A syringe has a syringe barrel into which a plunger stopper is inserted during a manufacturing process. A plunger rod is connected to the plunger stopper, and a backstop for preventing inadvertent removal of the plunger stopper from the syringe barrel is arranged at the proximal end of the syringe barrel. The backstop and the plunger rod are configured to form a combined assembly component which is adapted to be mounted to the syringe barrel in a combined manufacturing step. After mounting the combined assembly component to the syringe barrel, the backstop and the plunger rod are separated to allow conventional use of the syringe.

A reciprocating syringe that can be used in connection with existing syringe barrels and fittings. Some embodiments comprise a frame, adapted to retain two existing syringe barrels. The frame can accommodate fittings on one or both barrels. The invention also provides a plunger complex, comprising two plungers, each adapted for use with one of the syringe barrels. The two plungers are coupled such that pushing of each plunger into its barrel causes the other plunger to pull outwards relative to its barrel. The two plungers can be coupled by a flexible line attached to one plunger, routed from the plunger out of the corresponding barrel into the other barrel, and attached to the other plunger. The invention contemplates various frame configurations to accommodate desired line and pulley performance characteristics. Other embodiments comprise a frame adapted to retain an existing syringe barrel, and an auxiliary actuator mounted with the frame. Such an actuator can provide a syringe-like plunger operation, or can comprise other manipulable structures. The auxiliary actuator can be coupled to a plunger adapted for use with the syringe barrel, such that pushing the plunger into the barrel causes the actuator to move in a reversible manner, and moving the actuator in the reverse manner causes the plunger to pull outwards relative to its barrel. The invention also comprises various materials, methods of making, geometries and arrangements of parts, and accommodation of various specific existing syringe designs and applications.

Syringe barrels (11) are fitted with hypodermic needles (25) before the plastic is injected. For this purpose, the hypodermic needles (25) are introduced through the stationary part (5) of the injection mold (1) by a suitable transport device (transport rollers (33)).

Medical devices and syringes having reuse prevention features and methods of use thereof are provided. According to one or more embodiments, the syringe includes a barrel and a plunger rod including a stopper and an end wall with at least one portion that is removably engaged with the plunger rod, which prevents the creation of a vacuum between the stopper and barrel. One or more embodiments pertain to a single-use syringe which has a means for separating the plunger rod to prevent disassembly of the syringe prior to use. Methods of using a syringe according to embodiments of the present invention include an aspirating and expelling cycle followed by applying a force to the plunger rod in the distal direction to disable the stopper and prevent the creation of a vacuum between the stopper and syringe barrel.
