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 vials (4, 130) each having a septum at one end. The septum of each vial is pierced by a pair of hollow spikes (54, 56, 140, 142). One of the spikes is used to allow the liquid medication to be pumped out of the vial while the other spike is used to introduce air into the vial to replace the withdrawn liquid medication. Using a reciprocating piston-and-cylinder type pump, the vials are pressed a desired number of times according to how much medicine is to be driven into the syringe. The invention permits insulin users the freedom to quickly and easily select the proportions and amounts of insulin to be injected depending upon the user's current needs.
