ABSTRACT:
A medical syringe employs a capsule containing multiple doses of medication within a sealed storage chamber formed between concentric inner and outer walls. The inner wall forms a cavity including a delivery chamber from which a single dose of medication is ejected. The syringe includes an ejection port, an axial moveable plunger extending into the cavity and delivery chamber, and a body with a compartment that holds the capsule. With the plunger in a first position, the capsule is closed. With the plunger in a second position, the delivery chamber is filled with a single dose of medication. With the plunger in a third position, the single dose of medication is ejected from the delivery chamber though the injection port.
