摘要:
A single -use disposable syringe is provided which includes a hollow cylindrical body closed at a front end and an opening at a rear end. A first plunger is housed inside the hollow cylindrical body and being located substantially adjacent to the front end. A second plunger is located marginally behind the first plunger and a plunger rod traverses through the second plunger and have a projection formed at about the front end for engaging with the second plunger during a backward/retraction motion thereof. The plunger rod (2) cooperates with the first plunger (3) during a forward motion and pushes the same toward the front end for the first and the sole time, thereby expelling a fluid contained inside the hollow cylindrical body.
