A pharmaceutical container for drug delivery includes a barrel configured to slidably receive a stopper. The container exhibits a ratio of a break loose force (BLF) relative to a glide force (GF) of BLF/GF≤2 during a break loose and glide force test and a total glide force variation TGFV=GF.sub.max−GF.sub.min measured when the stopper is moved from a start position to its end position is TGFV<2 N.

Method and apparatus for manufacturing, filling and packaging medical devices and medical containers

Medical devices such as medical containers can be formed of glass and annealed which produces a clean device having a low bio-burden, or formed by plastic molding which produces a clean device. The clean devices are immediately transferred to a controlled environment such as a clean room or localized area to avoid the need to maintain cleanliness levels in an entire room. Syringe tip closures can be introduced into the housing assembly, where syringe barrels and tip closures are cleaned with filtered ionized air and the tip closures are coupled to the barrels. The syringe barrels can be filled with a substance and a closure member attached. While still in the housing assembly the syringe barrels can be formed into an array and placed in a clean outer container, which is then closed and sealed.

Application arrangement with a medicinal substance fluid

A pharmaceutical product includes a delivery syringe comprising a plastic receptacle and an oxygen-tight envelope which envelopes the delivery syringe in an oxygen-tight manner, wherein the plastic receptacle is filled with an oxygen-sensitive active pharmaceutical ingredient fluid and an inner surface of the plastic receptacle is siliconized at least in sections.

CRYOSYRINGE DESIGNED FOR STERILE LIQUID NITROGEN FREEZING, QUICK THAWING AND INJECTION OF CELLULAR SLURRIES
20170216531 · 2017-08-03 ·

An embodiment in accordance with the present invention is directed to a device for use as a cryosyringe and a cryo-storage vial. The device includes a first end and a second end and has an outer wall defining a lumen between the first and second ends. Both the first end and the second end include threads configured for attaching a first cap to the first end and a second cap to the second end. The device can also include a syringe plunger adapter, such that the cryo-storage vial is convertible into a cryosyringe to ensure sterility of the contents. Similarly, a luer-lock adapter can be included to further convert the device into a cryosyringe. The device and its components are formed from a cryo-resistant material. The device can therefore withstand liquid nitrogen temperatures necessary to preserve cell viability and be injected without compromising sterility to dispense the cellular therapy.

SLIDABLE RUBBER MATERIAL HAVING AN AMINO-MODIFIED INTERFACIAL MODIFICATION LAYER, AND METHOD FOR PRODUCING SAID SLIDABLE RUBBER MATERIAL

A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.

MEDICAL SYRINGE, GASKET FOR USE IN THE SYRINGE, AND METHOD OF USING THE SYRINGE
20170266386 · 2017-09-21 · ·

A laminated gasket to be inserted in a syringe barrel prevents leakage of a highly permeable liquid drug which may otherwise occur when an inert film of the gasket does not intimately contact an inner wall of the syringe barrel. The laminated gasket has a circumferential surface portion , a liquid contact surface, a bottom surface , and a threaded hole adapted to be in threaded engagement with a distal end portion of a plunger. The threaded hole has an internal thread provided on an inner peripheral surface thereof and including a plurality of periodic thread portions. Provided that an innermost periodic internal thread portion has a diameter Fl, that the other periodic internal thread portions each have a diameter F2 and that a distal one of periodic thread portions of an external thread provided on the distal end portion of the plunger has a diameter D1, a relationship F2>D1>F1 is satisfied.
