Abstract
Compression piston for an injection syringe (1) is cylindrically formed from hard plastic having a lower part is formed as a blunt cone. In the centre is a cylindrical space (2) which is filled with light flexible plastic, eg polyethene or similar material, which gives adequate resistance for compression of the substance to be injected, but at the same time allows the infected injection needle to perforate and be stably encapsulated in the cylindrical space (2) interior in a secure and inaccessible position (4).
