An enteral feeding syringe assembly includes a syringe including an engagement surface. A projecting connector portion extends from the engagement surface. A connector is configured for attachment to the syringe to connect the syringe to a fluid conduit or reservoir. The connector includes a male connector portion including a rim and a passage extending through the male connector portion. The projecting connector portion of the syringe is sized and shaped to be received in the male connector portion of the connector when the connector is attached to the syringe such that an exterior wall of the projecting connector portion sealingly engages the male connector portion within the passage of the male connector portion and the rim of the male connector portion engages the engagement surface of the syringe sealing the male connector portion around the projecting connector portion.

A synthetic-resin barrel for a syringe has an injection needle fixed to an open distal-end portion thereof or a distal-end portion thereof and is sterilized by radioactive rays or electron beams. The synthetic resin forming the barrel contains a phenol-based antioxidant. The amount of phenoxyl radicals of the synthetic resin measured by the electron spin resonance apparatus is 0.1 to 1.010.sup.12 spins/mg.

Disclosed are a closure system for an applicator attachment on a container for pharmaceutical preparations and to a use of the closure system, a syringe for medical purposes, including a container for pharmaceutical preparations and a closure system, and a method of assembling a syringe. The aforementioned operate such that splash prevention and a venting function are integrated in the closure system.

An automatic injection device including a housing, a chamber with a first compartment and a second compartment, and a seal structure between the compartments. The seal structure is initially in a sealing condition that seals the first compartment from the second compartment, where the seal includes a plug and an outer sealing member. The plug is slidably movable within the outer sealing member to convert the seal structure from the sealing condition to a mixing condition by opening a path between the first compartment and the second compartment. The automatic injection device also includes a needle assembly and an activation assembly. Activation of the activation assembly causes (1) pressurization of the first compartment, (2) the seal structure to convert from the sealing condition to the mixing condition, and (3) the first and second medicament components to be mixed and forced through the needle assembly.

A syringe barrel includes an barrel main body having a female luer at a distal end of the barrel main body, the female luer being configured such that a male luer is insertable into and connectable to the female luer; and a cap that is detachably attached to the female luer to close an opening of the female luer. The female luer has a female luer-side connector, and the cap is detachably attached to the female luer via the female luer-side connector. The cap includes an insertion part inserted into the female luer, a sealing part that seals the opening of the female luer, and a cap-side connector that is detachably engaged with the female luer-side connector.

One aspect relates to a device for mixing a polymethyl methacrylate bone cement formed of two starting components and for storing the starting components of the bone cement. The device has a tubular cartridge with a cylindrical interior. A powder is contained in a front of the cartridge and a container containing a monomer liquid is arranged in a rear of the cartridge. A discharge piston is arranged between the container and the powder, and a conveying piston is on the side of the container opposite the discharge piston. The discharge piston and the conveying piston are arranged in the interior of the cartridge movably in the longitudinal direction. A conduit is provided that connects the front part and the rear part of the interior of the cartridge to one another in a manner permeable for the monomer liquid and for gases and which is impermeable for the powder.

A closure piece for a powder syringe is proposed, having a main body, a sealing element, which is disposed on the main body such that it rests in a sealing manner against a distal opening of a powder syringe, when the closure piece is disposed in the closing position thereof on the powder syringe, and a channel, which passes through the main body and the sealing element and has a proximal and a distal end. The closure piece is characterized by a retaining element, which is configured and/or can be disposed such that, prior to an activation of the powder syringe, any powder from a chamber of the powder syringe is at least substantially, preferably completely, prevented from penetrating the channel, when the closure piece is disposed in the closing position thereof on the powder syringe.

A syringe assembly including a plunger rod having a first end, a second end, and a rod portion extending therebetween, wherein at least a portion of the rod portion is flexible is disclosed. The flexible portion of the rod portion allows a stopper to be moved between a first position and a second position within a syringe barrel while the overall length of the syringe assembly remains the same throughout the movement between the first position and the second position. In another embodiment, a syringe assembly including a restraining member adapted to communicate with the flexible portion of the rod portion such that movement of the first end of the plunger rod in a first direction actuates movement of the second end of the plunger rod in a second direction different than the first direction is disclosed.

A closure piece for a powder syringe has a main body and a sealing element. The sealing element is disposed on the main body such that it rests in a sealing manner against a distal opening of a powder syringe when the closure piece is disposed in the closing position thereof on the powder syringe. A channel passes through the main body and the sealing element and has a proximal and a distal end. The closure piece includes a retaining element configured and/or disposed such that, prior to an activation of the powder syringe, any powder from a chamber of the powder syringe is at least substantially prevented from penetrating the channel when the closure piece is disposed in the closing position thereof on the powder syringe.

A flow communication unit (240, 540, 640, 740, 840, 940, 1040, 1140, 1240) for establishing flow communication from a multi-use drug delivery device adapted for extended use, to a flow conducting device, wherein the drug delivery device comprises a reservoir comprising multiple doses of a liquid drug formulation, wherein the reservoir is adapted to pressurize the liquid drug formulation, wherein the flow conducting device (230) is adapted for conducting the drug to the subcutaneous tissue of a subject, wherein the flow communication unit is adapted for being in an unconnected and a connected configuration, whereby the flow communication unit (240, 540, 640, 740, 840, 940, 1040, 1140, 1240) is adapted to enable the extended use of the multi-use drug delivery device.
