<p>Disposable syringe made of synthetic material for medical use, comprised of a cylinder (1), a piston (2) provided with a piston rod (3) guided by the wall of the cylinder to provide for a clearance, and of a cover (4), the piston (2) being releasably connected to the piston rod (3). The piston (2) is at least partially flexible since wall elements of considerably reduced thickness are provided on the piston body. The cover (4) comprises a stable sliding guide which is long enough for the piston rod (3), so that the piston (2) is not subjected to deformations of the rod which result from an excentric force application when the piston is in an end position, as well as fromt the tendency to flexure of the relatively thin piston rod (3). </p> |
