PROBLEM TO BE SOLVED: To evenly spray an adhesive, prevent the adhesive from being easily hardened, and easily remove the hardened adhesive even upon the formation thereof on the end of an adhesive spray nozzle. SOLUTION: A spray head is formed out of a spray base part 1 having two medical fluid passages 11 and 12, as well as an air passage 13, two nozzles 2 and 3 respectively connected to the medical fluid passages 11 and 12 at the end of the spray base part 1, and an air nozzle 4 externally coupled to the nozzles 2 and 3 in a concentric form. The air nozzle 4 is slidable over a range from a position adjacent to the tip end of the spray base part 1 to a a position away therefrom. Also, the nozzles 2 and 3 are housed in the air nozzle 4 at a position adjacent to the end of the spray base part 1. Furthermore, the nozzles 2 and 3 project from the air nozzle 4 at a position away from the tip end of the spray base part 1. |
