PURPOSE:To permit easy medication treatment in the narrow mouth of a patient by connecting freely turnably the root end part of a long-sized tube for leading out chemical liquid in the chemical liquid injecting part formed in a push botton member, and mounting a nozzle to the tip formed by bending the end of said tube. CONSTITUTION:Only the 1st and 2nd tubes 5, 11 for leading out chemical liquid projecting from a push-button member 1 are inserted into the mouth of a patient, and a doctor presses the member 1 by erecting the chemical liquid sprayer at the position where the nozzle 14 at the tip of the tube 11 is directed to the disease part in the mouth. A piston rod 16, regulating member 18 and check valve 10 operating cooperatively with the member 1 move downward by overcoming the regenerative force of a compression spring 22. The annular projecting part 31 at the bottom end of the rod 16 fits into the annular recess 30 on the inside circumference of a cylinder 17 and therefore the chemical liquid stored in the recess 30 is pressurized. The chemical liquid is discharged through the chemical liquid passage 30 between the rod 16 and the member 18, a flow passage 2 and conduit passages 8, 15, from the nozzle 14. |
