PROBLEM TO BE SOLVED: To provide an applying instrument which has a mechanism to prevent clogs with chemicals when using an instrument for applying tissue adhesive intermittently and enables us to use the instrument continuously without wasting the instrument and the cost for pharmaceutical preparation. SOLUTION: The instrument is provided with a switch to send aseptic gas at the head of the sprayer and works to remove chemicals left at the tip of a passage for circulating chemicals by the aseptic gas when stopping supply of the air. The head 1 of the sprayer has two inlets 2 for chemicals at its end, an inlet 3 for aseptic gas in its middle. Also, multiple discharging nozzles 4 for the chemicals and spray nozzle 5 for aseptic gas to spray the chemicals, placed circular outside of each discharging nozzle 4 while sharing the same axis with the discharging nozzle 4, are equipped at the front end of the head 1 of the sprayer. The inlet 3 for aseptic gas has a switch 6 with a system of turncock inside the head 1 of the sprayer, and turning the switch 6 allows to send aseptic gas supplied from outside to the passage for circulating aseptic gas or a branched, circulating passage located inside the head 1 of the sprayer, or to stop sending the gas. |
