Arrangement for applying a tissue adhesive
First Claim
1. An arrangement for applying a tissue adhesive that solidifies in situ by uniting with blood-clot-promoting coagulation factors, comprising:
- a plurality of syringe bodies ending in joining pieces;
a piston in each of said plurality of syringe bodies for commonly actuating said syringe bodies;
a connecting head attached to said joining pieces of said syringe bodies and provided with a separate conveying channel for each of the components to be applied;
each of said syringe bodies having equal effective strokes; and
one of said syringe bodies having a cross-sectional area that is two to nine times larger than the cross-sectional area of the remaining syringe bodies, said one syringe body containing an adhesive protein solution having a fibrinogen content of from 3 to 12%.

Abstract
An arrangement for applying a tissue adhesive based on human or animal proteins, to seamlessly or seam-supportingly connect human or animal tissue or organ parts by uniting with blood-clot-promoting coagulation factors (thrombin). The arrangement includes a plurality of syringe bodies commonly actuatable by pistons and to which a connecting head is attachable. The syringe bodies have equal effective strokes, yet one of them, i.e., that destined to contain the protein solution, has a cross sectional area that is two to nine times larger than the other one(s). There may be applied tissue adhesives having a fibrinogen content of from 2 to 12%.

8. A device for dispensing a plurality of interreactable fluid, comprising:
-
a plurality of syringe bodies; a connecting head interconnecting the discharge ends of each of the syringe bodies; first piston means in each of said syringe bodies for actuating said syringe bodies; first floating piston means in one of said syringe bodies for dividing said one syringe body into a first chamber and a second chamber; and first by-pass means in said one syringe body for allowing fluid from said second chamber to mix with fluid in said first by-pass means in said one syringe body for allowing fluid from said second chamber to mix with fluid in said first chamber when said first floating piston means is adjacent said first by-pass means; wherein said one syringe body has a cross-sectional area that is two to nine time larger than the cross-sectional area of the remaining syringe bodies. - View Dependent Claims (9, 10)
