  • Patent number: 9902508
    Abstract: A device and method are provided for storing substances separately, and for mixing the substances prior to use. The device defines at least one first chamber for receiving a first substance, and at least one second chamber for receiving a second substance. A first sealing portion is located between the first and second chambers and is movable between a closed position preventing fluid communication between the chambers, and an open position permitting fluid communication between the first and second chambers for mixing the substances. First and second penetrable and resealable portions in fluid communication with the first and second chamber(s), respectively, may be used for filling by penetrating them with an injection member and introduce the substances therethrough and into the respective chamber, and resealing the injection apertures and the substances within the respective chamber.

  • Publication number: 20170362016
    Abstract: A dispenser for holding multiple doses of fluids or other substances, and for dispensing the substances, has a vial, a flexible bladder received within the vial, and a variable volume storage chamber formed between the bladder and vial. A filling valve is coupled in fluid communication with the storage chamber and defines (1) a normally closed, fluid-tight position hermetically sealing the storage chamber from the ambient atmosphere, and (2) an open position allowing the passage of fluid through the valve both to evacuate the storage chamber and to introduce fluid through the valve to fill the storage chamber. A pump is coupled in fluid communication with the storage chamber for pumping fluids out of the storage chamber. A dispensing valve is coupled in fluid communication with the pump and defines (1) a normally closed, fluid-tight position preventing the passage of fluid out of the dispenser, and (2) an open position for dispensing pumped fluid therethrough.

  • Patent number: 9737435
    Abstract: A device has a first part with a valve seat and storage chamber, and a second part with a flexible valve cover and actuator. The storage chamber may be formed from a pre-form blow-molded into a flexible pouch defining a variable-volume storage chamber. The flexible valve cover and valve seat form a normally closed valve seam therebetween. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one-way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam, and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam. The one-way valve may have anti-spritz features for using the device to dispense a substance, such as to the eye.

  • Patent number: 9725228
    Abstract: A dispenser for dispensing a fluid includes a rigid vial that has a main fluid chamber containing a fluid, and a pump assembly that is in fluid communication with the main fluid chamber and is configured to dispense a predetermined quantity of fluid from the main fluid chamber. A flexible bladder is provided which is located within the main fluid chamber and is configured to expand to fill the ullage created within the main fluid chamber during dispensing of fluid by the pump assembly. The resilient bladder tends to force itself outwardly toward the rigid vial and, in turn, increases the pressure within the main fluid chamber in comparison to the interior of the bladder to thereby prevent the ingress of air or vapors through the bladder or otherwise into the main fluid chamber.

  • Publication number: 20170203860
    Abstract: Apparatuses and methods for controlling transfer of substances to a formulation container to provide a predetermined formulation. A controller may utilize one or more of a flow time, flow rate or a volume of transfer of substance. Barcoded and RFID-containing components may be used to determine what connection or disconnection has been made, and/or time thereof. Process compliance may compare measured or determined flow or connection time, flow rate and/or the transfer volume to a predetermined time, flow rate and/or volume, and adjust one or more of the time, flow rate and/or the volume of the transfer. An optional holder or cradle is configured to receive therein a fluid transfer connector formed by the connection of first and second connector portions, each in fluid communication with a flow conduit or channel that delivers substance to or receives substance from its respective connector portion, only if the connector portions are properly connected together.

  • Publication number: 20170158365
    Abstract: An injection member penetrates an elastic septum of a device defining a sealed, empty, sterile chamber in fluid communication with the septum. During penetrating, an annular interface is formed between the septum and the injection member extending axially between a penetration point on an interior surface of the septum in fluid communication with the sterile chamber, and an exterior surface of the septum engaging the injection member. The injection member is de-contaminated by (i) friction between the septum and injection member at the annular interface, and (ii) elongation of the septum at the annular interface. A substance is introduced through the injection member and into the sterile chamber of the device, the injection member is then withdrawn from the septum, the septum reseals itself at the resulting penetration aperture, and the chamber is maintained sterile throughout the foregoing steps.
