Abstract

There is disclosed a syringe assembly for the storage and application of a biological multi-component material. Its assembly parts are a syringe device including several parallel syringe bodies interconnected by a connection part, which syringe bodies are filled with the individual components of the multi-component material, include coni and are closed by pistons; an actuation device for this syringe device, which includes piston rods associated with the pistons and a common grip element; and a dispensing element to be attached to the coni of the syringe bodies. The filled syringe bodies, which are closed by separate piston plugs, constitute a one-piece syringe unit with the connection part. The connection part leaves a recess between the syringe bodies on one of the ends of the syringe unit for receiving a protection means shielding off the other syringe body/ies when filling the syringe bodies. The grip element is connected in one piece with the piston rods, thereby forming a one-piece piston rod unit separate from the syringe unit including the piston plugs.
