<P>PROBLEM TO BE SOLVED: To provide a chemical fluid infusion device which enables stable supply of a chemical fluid to an affected area by a simple structure. <P>SOLUTION: Rotation is applied to a housing 1 where a syringe 7 for supplying the chemical fluid is attached by a handle 6. The handle 6 includes a disk 4 with a slanting part slanting in the circumferential direction. A piston pin 2b moves along the slanting part, and a piston 2 moves in the axial direction inside the housing when the handle 6 is operated rotatably. The piston 2 is biased into the direction opposite from the disk by a spring 3 with one end locked with the housing 1. Because of a syringe barrel 7a fixed to the housing 1 and a syringe plunger 7b fixed to the piston 2, the syringe plunger 7b is moved axially, and the chemical fluid is dispensed from the syringe barrel 7a by the handle 6a operated rotatably. <P>COPYRIGHT: (C)2004,JPO |
