Abstract
A telescoping syringe suitable for use with medications and other ejectable or injectable fluids is presented. The syringe includes a plunger, a barrel, and a valve. The plunger is extendible from and retractable into the barrel. The plunger defines a first reservoir. The barrel defines a second reservoir as the plunger is extended from the barrel. The valve is disposed at one end of the plunger adjacent to a nipple extending from the barrel. A first sealing interface is formed by the valve and a distal wall along the barrel adjacent to the nipple. A second sealing interface is formed by an annular flange along the one-way valve and an annular groove along the plunger. A third sealing interface is formed by the valve and a circumferential end along the plunger. The sealing interfaces are closed prior to extension of the plunger from the barrel thereby preventing a gas from entering and a fluid from existing the first reservoir. The sealing interfaces are open when the plunger is extended from the barrel so that the gas enters the first reservoir via an inlet(s) along the annular groove and fluid is communicated into the second reservoir via an outlet(s) along the valve. The second and third sealing interfaces are closed when the plunger is retracted into the barrel thereby allowing fluid to exit the second reservoir via the nipple.
