Device for dispensing liquid from a sterile packaging bottle with bi-functional membrane
The invention proposes a biological protection membrane which is mounted, in a device for dispensing liquid from a sterile packaging bottle, across a fluid-circulation duct, in the path of the liquid extracted from the bottle and the outside air which is drawn into the bottle. The membrane (7) is made partially of a hydrophilic material and partially of a hydrophobic material. Both the hydrophobic portion (23) and the hydrophilic portion (22) are made from a polymer base, laden in the body thereof with a biocidal agent that is active in the destruction of bacteria by the ionic oxidation effect. The circulation of fluids through the membrane (7) is organised so as to promote the ionic action on the flow of outside air in the hydrophobic material, and to drive the ionically charged active agent by the liquid passing through the membrane in the hydrophilic portion thereof. A porous buffer (8), inserted in the path of the fluids on the inside of the membrane, collects the active agent extracted from the membrane by the remaining liquid not dispensed, passing through the membrane from the outside towards the inside.
System and method for storing pharmaceuticals or biological media
A system for storing pharmaceuticals or biological media comprising a bag including a flexible sidewall defining an opening; and a vent coupled with the flexible sidewall at the opening and defining a vent passageway between an internal volume of the bag and an external environment, wherein the vent is coupled with the bag at a location spaced apart from and above the opening.
PRESERVATIVE REMOVAL FROM EYE DROPS
A particulate plug for removing a preservative from a solution, suspension, or emulsion comprising a drug is presented. The plug comprises microparticles of oxidized polyolefin (OxPO). The microparticles are irregular-shaped rigid aggregates and are sized and packed to yield a hydraulic permeability greater than 0.01 Da. The OxPO have absorbed portions of a preservative to be removed and/or a drug for delivery in solution, as can the copolymer.

AMPOULE CLOSURE
A closure for an ampoule, the closure comprising: a cap portion arranged to engage with a broken neck of an opened ampoule; and a cylindrical skirt portion extending from the cap portion, the skirt portion being elastically deformable and being arranged to move from a first position in which it is at least partially folded back on itself to a second position in which it is unfolded and extends away from the cap portion. The closure can close off an opening such as that formed in an ampoule when the neck is snapped and the top removed. As the cap portion engages with the broken neck, it reduces the chances of users receiving lacerations from the sharp edges. The cap portion also seals the ampoule, preventing the contents from being spilled and/or wasted. The closure also provides a degree of impact protection, reinforcement and strengthening to the now weakened open end of the ampoule, e.g. in case the ampoule is dropped. The skirt portion not only provides a seal around the ampoule body by being in close contact therewith, but also holds the cap portion firmly against the broken rim of the open ampoule, thus holding the closure in place by means of the friction between the skirt portion and the outer surface of the ampoule body.
Collapsible Fluid Reservoir with Filter
A collapsible fluid reservoir may include a flexible container, a flexible filter, a first inflow line, a second inflow line, and an outflow line. The container may include a first sheet and a second sheet defining an internal space therebetween for containing a biological fluid. The filter may be disposed within the internal space and attached to the container along an entire periphery of the filter. The filter may include a first side facing the first sheet and a second side facing the second sheet. The first inflow line and the second inflow line each may be disposed at least partially within the interior space and between the first side of the filter and the first sheet. The outflow line may be disposed at least partially within the interior space and between the second side of the filter and the second sheet.
Sterile Product Bag with Filtered Port
A sterile product bag includes a bladder, a stem, a filter, and a vial adaptor. The bladder has a perimeter seal and defining a sterile chamber. The stem extends through the perimeter seal and has an inlet end outside of the perimeter seal and an outlet end in fluid communication with the chamber. The filter is disposed in line with the stem and has a filter membrane with a nominal pore size in a range of approximately 0.1 m to approximately 0.5 m. The filter membrane is shaped as a hollow fiber with a wall and pores residing in the wall of the fiber. The vial adaptor includes a sterile hollow cannula, a sheath, and a peelable closure. The cannula is in fluid communication with the chamber of the bladder. The sheath is disposed outside of the bladder and connected to the hollow cannula. The sheath includes an interior cavity into which the hollow cannula extends. The peelable closure extends across an opening of the sheath to seal the interior cavity.
Filtered Product Bag with Compact Form Factor
A product bag includes a bladder and an elongated filtration device. The bladder includes opposing first and second film layers defining a product chamber. The first and second film layers are sealed together along a perimeter seal extending along at least a portion of a perimeter of the bladder. The elongated filtration device includes a housing, a filtration membrane disposed in the housing, an inlet adapted for receiving a fluid to be filtered, and an outlet in fluid communication with the product chamber. A majority of the elongated filtration device is embedded between the first and second film layers of the perimeter seal of the bladder to provide for a compact form factor.
Medical Product Including Pre-Filled Product Bag
A medical product includes a bladder, a filtration device, and a sterile product concentrate. The bladder has a perimeter seal and defining a sterile chamber. The filtration device includes a stem and a filter membrane disposed in line with the stem. The stem extends through the perimeter seal and has an inlet end accessible from outside of the perimeter seal and an outlet end in fluid communication with the sterile chamber. The filter membrane can have a nominal pore size in a range of approximately 0.1 m to approximately 0.5 m, wherein the filter membrane is shaped as a hollow fiber with a wall and pores residing in the wall of the fiber. The sterile product concentrate is disposed in the sterile chamber and adapted to be reconstituted by the introduction of a pharmaceutical fluid into the chamber through the filtration device.
STERILE SOLUTIONS PRODUCT BAG
A sterile solution product bag includes sterilization grade filter integrated directly into the product bag such that microbial and particulate matter filtration can be performed using the filter directly at the point of fill. The filter can include a hollow fiber filter membrane contained in a stem connected to a bladder of the product bag.
