<P>PROBLEM TO BE SOLVED: To provide a biological tissue adhesive applicator which does not waste a medical liquid and does not occur clogging at the time of being intermittently used. <P>SOLUTION: The biological tissue adhesive applicator for mixing and spraying two kinds of liquid chemicals includes: a spray head body 1 having a space in the inside; an aseptic gas inlet 3 injectable of an aseptic gas 12 to an aseptic gas distribution chamber 13; two liquid chemical inlets 2 on the rear end part side of the body 1; two liquid chemical discharge nozzles 4 at the distal end part of the body 1; and two aseptic gas jetting ports 5 arranged coaxially to the liquid chemical discharge nozzles 4 and roughly annularly on the outer periphery. Further, inside the aseptic gas distribution chamber 13, the applicator includes: two liquid chemical distribution tubes 6 connecting the two liquid chemical inlets 2 and the two liquid chemical discharge nozzles 4; and a cover tube for covering the liquid chemical distribution tubes 6 are provided. In the long axis direction of the cover surface of the liquid chemical distribution tubes 6 and the cover tube, at least one aseptic gas distribution groove 8 for communicating the aseptic gas distribution chamber 13 and the lumen of the liquid chemical distribution tubes 6 is provided. <P>COPYRIGHT: (C)2011,JPO&INPIT |
