Abstract
Abstract An arrangement for applying a tissue adhesive on the basis of human or animal proteins for seamlessly or seam-supportingly connecting human or animal tissue or organ parts, sealing wounds, stopping bleedings and the like, which tissue adhesive is formed in situ by bringing together solutions of the proteins and of clot-promoting coagulation factors, includes a holding device for a plurality of syringe bodies ending in coni. In order to achieve a reliable mixing of the tissue adhesive components by single-hand operation with a premature hardening of the components prior to reaching the laceration site being prevented, the coni of the individual syringe bodies are connected by a collecting head having separated conveying channels for the components of the tissue adhesive emerging from the coni. A common actuating device is provided for the plungers of all syringe bodies.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
In an apparatus for applying a tissue adhesive on the basis of human or animal proteins to be used for seamlessly or seam-supportingly connecting human or animal tissue or organ parts, for sealing wounds, for stopping bleedings and the like, said tissue adhesive being formed in situ by bringing together at least two components comprised of solutions of proteins and clot-promoting coagulation factors, and of the type including a plurality of standardized one-way syringe bodies of synthetic material, said syringe bodies accommodating plungers and ending in coni, and a holding means provided for said plurality of syringe bodies, the improvement which comprises a collecting head connecting said coni of said syringe bodies, separated conveying channels provided in said collecting head for said at least two components emerging from the respective one of said coni, a guide rod penetrating said holding means, and a common actuating means being guided along said guide rod provided for the plungers of said syringe bodies.
Claim 2
Dependent Claim
160 words
In an apparatus for applying a tissue adhesive on the basis of human or animal proteins to be used for seamlessly or seam-supportingly connecting human or animal tissue or organ parts, for sealing wounds, for stopping bleedings and the like, said tissue adhesive being formed in situ by bringing together at least two components comprised of solutions of proteins and clot-promoting coagulation factors, and of the type including a plurality of standardized one-way syringe bodies of synthetic material, said syringe bodies accommodating plungers and ending in coni, and a holding means provided for said plurality of syringe bodies, the improvement which comprises a collecting head connecting said coni of said syringe bodies, separated conveying channels provided in said collecting head for said at least two components emerging from the respective one of said coni, a guide rod penetrating said holding means, and a common actuating means being guided along said guide rod provided for the plungers of said syringe bodies.
Claim 3
Dependent Claim
20 words
An apparatus as set forth in claim 1, further comprising a mixing needle to be slipped onto said collecting head.
Claim 4
Dependent Claim
35 words
An apparatus as set forth in claim 1, further comprising a slip-on cone provided on said collecting head and having an end side at which said separated conveying channels have their mouths closely adjacently arranged.
Claim 5
Dependent Claim
41 words
An apparatus as set forth in claim 1, further comprising supply channels for sterile gases laid at an angle to one another and having outlets in the region of which said separated conveying channels of said collecting head have their mouths.
Claim 6
Dependent Claim
46 words
An apparatus as set forth in claim 4, wherein said outlets of said supply channels have axes directed at an acute angle to one another so as to provide an angle vertex, lying at a distance in front of the mouths of said separated conveying channels.
Claim 7
Dependent Claim
31 words
An apparatus as set forth in claim 5, wherein said angle vertex lies at a distance of 10 to 20 cm in front of the mouths of said separated conveying channels.
