Abstract
A device and method for filling a conventional disposable plastic syringe with a mixture of insulins. The mixing device includes a pair of disposable cartridge assemblies each containing a different type of medication to be mixed in the syringe and a pair of medication dispensing mechanisms for dispensing the medication out of a respective cartridge. Each dispensing mechanism permits one to specify the dose of medication to be dispensed and drives a plunger into its respective cartridge a specific distance based on the specified dose. The mixing device also includes a syringe holder assembly that holds a syringe until a mixed dose of medication must be dispensed and provides proper alignment of the cannula of the syringe with each cartridge assembly during mixing.
