Publication number: 20200085691Abstract: A medication compounding system is described that is capable of receiving one or more medications and diluents and that includes an array of moveable transfer cartridges to access a medication container and to transfer medication. The transferred medication may be joined with a diluent to form a compounded medication. The resulting compounded medication may then be directed to a filling port where a compounded medication container may be coupled. A second medication container may align with a second transfer cartridge to transfer a second medication. Because the device may comprise one or more medications and diluents, a series of compounded medications may be created using an individual transfer cartridge for each medication.Type: ApplicationFiled: November 22, 2019Publication date: March 19, 2020Inventors: George MANSOUR, Christopher ZOLLINGER, Jonathan YEH, Neil QUITOVIERA
