  • Patent number: 11191902
    Abstract: A combination plunger, a mixing device and a mixing syringe including the same are provided. The mixing syringe includes concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. The combination plunger includes a mixing plunger and a delivery plunger and a biasing means. The mixing plunger is slidably located in the outer chamber and translated by coordinated depression of the delivery plunger to transfer a first substance from the outer chamber to mix with a second substance in the inner chamber. After the mixing stage is complete, the delivery plunger is disengaged from the mixing plunger and permitted, such as by rotation, to be further depressed in the axial direction to deliver fluid contents of the mixing syringe to a recipient. The mixing syringe needle is then retracted as result of engagement by the delivery plunger and activation of the biasing means.

    Abstract: A method of storing and delivery a drug, such as by lyophilizing and reconstituting, comprises performing both storing and delivering with the same container closure assembly. The container closure is assembled in a preparation configuration during which lyophilization occurs. After lyophilizing, the powdered drug is forced into a spiral channel in the container closure assembly by a plunger. The plunger leaves substantially no head space for the powdered drug, and the assembly is sealed thereby now being in the storage configuration. For delivery of the stored powdered drug, a syringe of diluent is introduced to the container assembly thereby changing the assembly to the delivery configuration. The spiral channel is continuous between an input end and a delivery end with the delivery end being in fluid communication with a delivery outlet of the assembly. The assembly includes a diluent flow path that forces the diluent into a spiral channel at only the input end.

  • Patent number: 8357117
    Abstract: A device for delivering an agent into breast milk while breastfeeding. In one embodiment, the device includes a breast shield modified to engage a non-woven material which has been impregnated with a milk soluble active agent such as sodium dodecyl sulphate (SDS). A lactating animal, e.g. a woman, uses this agent-delivering breast shield during breastfeeding to administer prophylactic or therapeutic agents to a suckling infant. The inventions are particularly well suited to preventing transmission of HIV virus from mother to child. Alternatively, the agent-laden material could be used with a baby bottle nipple or pacifier.

  • Publication number: 20120203205
    Abstract: A system and method for intravenous, intramuscular, or subcutaneous delivery of a reconstituted medication fluid with simultaneous, uninterrupted delivery of a primary fluid. A medication fluid is prepared by reconstituting a medication with a primary fluid as diluent. A bag adapted to receive a medication is retro-primed with primary fluid from a primary bag. The primary fluid mixes with the medication to reconstitute the medication and form a medication fluid. A medication delivery system and method according to the present invention allows for the continuous infusion of primary fluid both during and after the administration of a reconstituted medication, using a closed system with reduced opportunities for contamination and infection.
