ABSTRACT:
A syringe assembly including a plunger rod and a plunger tip which are designed to provide a low frictional resistance against the interior surface of the syringe barrel while the plunger rod is at rest but which will increase the sealing pressure between the plunger tip and the interior surface of the syringe barrel in proportion to the amount of force applied to the plunger rod. Additionally, the plunger rod may be moved in the syringe barrel in a laterally offset manner with respect to the longitudinal axis of the syringe barrel without significantly affecting the seal between the plunger tip and the syringe barrel.
