Disposable unit-dose jet-injection syringe for pre-filled and/or transfilled liquid injectable medical drug or vaccine products and method thereof
First Claim
1. A method of injecting a unit dose of medicine, comprising:
- a. connecting a bulk container of the unit dose to a driving system;
b. connecting a syringe to the driving system, the syringe having a rear open end, a forward closed end and a cavity positioned in between;
c. drawing the unit dose from the bulk container through a channel in a piston in the cavity;
d. activating the piston through the cavity toward the forward closed end of the syringe; and
e. injecting the unit dose by the piston through a jet orifice positioned on the forward closed end.

Abstract
A disposable unit-dose jet injection syringe having a cylindrically shaped syringe body. The syringe body has a rear open end and a forward closed end. The rear open end has an enlarged diameter forming a flange that retains the syringe to the driving system during the injection cycle. The closed end has an small area coined by a stamping process. A jet orifice is punched through the small area of the closed end. A cavity formed in syringe body is configured to hold a unit dose of liquid, drug, or biological. A piston is slidably engaged within the body to inject the unit dose. A driving system activates the piston to inject the unit dose out of the jet orifice. A method of manufacturing a jet injection syringe is also provided. A method of injecting a medicine is also provided.
