ABSTRACT:
A medication dispenser (2, 120) is used to directly fill a syringe (8, 134) with measured amounts of one or more liquid medications, typically two different types of insulin, from containers, such as vials (4, 6) and cartridges (230, 232, 234) each having a septum at one end; each cartridge has a pierceable piston (256) at the other end. The septum of each container is pierced by hollow liquid spikes (54) while hollow gas spikes (56) pierce the septum of the vial and the piston of the cartridge. Liquid is pumped out of the container and air is replaced into the container through the liquid and gas spikes. Two of the cartridges can contain a diluent (231) and a lyophilized component (233) respectively; the diluent in the first cartridge can be pumped into the second cartridge through a one-way valve to create a mixed pharmaceutical which is then pumped into the syringe, with or without another pharmaceutical.
