PROBLEM TO BE SOLVED: To convert a fluid force-feeding syringe having a simpler and cheaper arrangement than a suction syringe into a suction syringe that allows a single- handed, smooth and easy sucking operation, by means of an outer cylinder holding member to which the outer cylinder of the syringe is removably attached and finger grip member removably attached to the finger rest part of an inner cylinder. SOLUTION: An adapter 20 comprises an outer cylinder holding member 21 having an outer cylinder supporting part 23 at its front end, a second finger rest part 24 formed in the shape of a disc at its rear end, and a guide part 25 of a predetermined length therebetween, a connecting body part 27, and a pair of second finger rest parts 28 projecting to the right and left of the connecting body part 27, so that a flange part 7 provided at the outer cylinder 2 of a syringe 1 functions as a finger rest part, and so that the disc part 1 of an inner cylinder 3 functions as a finger grip part. The second finger grip part 28 connected to the inner cylinder 3 is located closer to an end than the second finger rest part 24 connected to the outer cylinder 2, so that, when they are brought close to each other, the inner cylinder 3 is displaced in the direction in which it is pulled out of the outer cylinder 2. |
