  • Publication number: 20130253580
    Abstract: An adhesive applicator for biological tissue (100) includes a nozzle body (1), a gas inlet (2), medical fluid inlets (3a, 3b), medical fluid outlets (4a, 4b), medical fluid tubes (5a, 5b), a gas outlet (6), communication paths (8a, 8b), and a check valve (7b). The gas outlet (6) is located close to the medical fluid outlets (4a, 4b), and configured to eject gas loaded through the gas inlet (2) in the nozzle body (1) to thereby atomize medical fluids and mix them together. The communication paths (8a, 8b) communicate between inside of the nozzle body (1) and inside of the medical fluid tube (5b). The check valve (7b) is located between the communication paths (8a, 8b) and the medical fluid inlet (3b). The check valve (7b) only allows one-way flow of the medical fluid from the medical fluid inlet (3b) into the medical fluid tube (5b).
