<p>A convertible syringe assembly (10) mainly comprising a barrel (101) for collecting withdrawn fluid, a plunger (102) passing inside the barrel having a plurality of longitudinal spokes (110) around the central axis (10a) of the syringe. A collapsible slot (112) exists in at least one of the spokes (110) that allows lateral movement of the plunger (102) with respect to the central axis (10a). The lateral force on the plunger (102) bends the plunger towards the collapsible slot (112). The reactionary force resists the lateral force on the plunger (102), pushing it back towards the central axis (10a) of barrel of the syringe. This reactionary force is cancelled due to collapsible slot (112), thereby facilitating smooth removal of plunger (102) from barrel (101). The convertible syringe (10) is sealed by plunger cap (113) at the top and by nozzle cap (106) at the bottom, thus converting the syringe into a container.</p> |
