Syringe assembly for the storage and application of a biological multi-component material
First Claim
1. A syringe assembly for storing and applying a biological multi-component material, comprising as separate assembly components:
- (a) a syringe device including at least two parallel syringe bodies ending in coni and each filled with one of said multi-component material, a connection part connecting said syringe bodies, and piston plugs closing said syringe bodies in the filled state;
(b) an actuation means including piston rods associated with said piston plugs and a common grip element; and
(c) a dispensing element capable of being attached to said coni of said syringe bodies;
whereinsaid syringe bodies, after having been filled and separately closed by said piston plugs, constitute a one-piece syringe unit with said connection part,said connection part, on one end of said syringe unit, leaves a recess between said syringe bodies, andsaid grip element is connected in one piece with said piston rods, thus forming a one-piece piston rod unit separate from said syringe unit including said piston plugs.

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.

- 11. A syringe device for storing and applying a biological multi-component material, comprising at least two parallel syringe bodies made of a synthetic material, ending in coni and each filled with one of said multi-component material, at least one connection part adapted to connect said syringe bodies and constituting a one-piece syringe unit with said syringe bodies, and piston plugs adapted to close said syringe bodies, wherein said connection part, on one end of said syringe unit, leaves a recess between said syringe bodies.

34. A method of producing a filled sterile syringe device including at least two parallel syringe bodies filled with a biological multi-component material, a connection part adapted to connect said syringe bodies and constituting a syringe unit therewith, and piston plugs adapted to close said syringe bodies, said connection part leaving a recess between said syringe bodies on one end of said syringe unit, which method comprises the steps of
providing a sterile one-piece syringe unit, sealing each of said syringe bodies on one of its ends, introducing a protection means into said recess for for shielding off the respective other of said at least two syringe bodies, automatically filling each component of said biological multi-component material in the respective one of said syringe bodies on its other end in a filling station and under sterile conditions, and closing said syringe bodies with said piston plugs being sterile.
