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 disposable unit-dose jet injection syringe, comprising:
- (a) a cylindrically shaped syringe body having a rear open end and a forward closed end, the rear open end having a flange, the forward closed end having a small area coined by a stamp process;
(b) a jet orifice through the small area of the forward closed end; and
(c) a piston slidably engaged within the cylindrically shaped syringe body to form a cavity, the cavity configured to hold a unit dose of a medicine.

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.
