1. A liquid-administration device comprising:
a hollow needle;
a fixing part that surrounds and is fixed to the outer periphery of the proximal end of the needle;
a connecting pipe attached to a protruding part that protrudes from the fixing part to the side thereof that is opposite to the needle, and in communication with the needle, the connecting pipe being configured such that a distal end of a syringe and a hematocrit tube are fittable to the pipe from the side that is opposite to the needle; and
a holding part that protrudes outward from the outer peripheral surface of the fixing part;
wherein the connecting pipe comprises a first connecting portion on the distal end thereof and a second connecting portion on the proximal end of the first connecting portion,
wherein the first connecting portion is connected to the protruding part at the distal end thereof, and has an inner diameter that corresponds to the outer diameter of the hematocrit tube, the hematocrit tube being inserted in the first connecting portion from the side opposite to the needle to be detachably fitted to the inside of the first connecting portion, and
wherein the second connecting portion is connected to the first connecting portion on the distal end thereof, and has an inner diameter that corresponds to the outer diameter of the distal end of the syringe on the proximal end thereof, the distal end of the syringe being inserted in the second connecting portion from the side opposite to the needle to be detachably fitted to the inside of the second connecting portion.
