PROBLEM TO BE SOLVED: To provide a low-cost drug administering device that has stability when installed and can administer a fixed amount of chemical accurately through a simple operation. SOLUTION: An earring type drug administering device 1 is formed into an earring shape by mounting a chemical-administering housing 4 on one end of a clamp ring 3, and mounting a pressing tool 5 on the other end of the clamp ring 3. A chemical storage cylinder 7 storing a chemical 24 is provided inside the housing 4, a piston 9 having a control rod is fitted into the chemical storage cylinder 7, and a control part 10 at the end of the control rod is provided to project from the housing 4. Since the device 1 is designed so that the distance that the piston 9 is lowered by the lowering of the clamp part 10 is held constant, a fixed amount of chemical can be administered to the skin of a subject by a single operation of pushing the control part 10. |
