Abstract
A telescoping syringe suitable for use with medications and other materials is presented. The telescoping syringe includes a valve, a plunger, and a barrel. The valve further includes a barrier, an outlet(s) through the barrier, and an annular extension extending from the barrier. The plunger further includes an inlet(s) and a first side wall with a proximal wall. The barrel includes a second side wall with a distal wall at one end and an open end at another end. The plunger is extendable from and retractable into the barrel at the open end via slidable engagement between first and second walls. The valve directly contacts one end of the first wall so that an annular flange slidingly engages an annular groove. The valve and the barrel slidingly contact the plunger so as to open and to close the inlet(s) and/or the outlet(s). The inlet(s) in the open position permits gas to enter a first reservoir within the plunger as fluid is transferred from the first reservoir through the outlet(s) in the open position to a second reservoir within the barrel.
