PROBLEM TO BE SOLVED: To provide a liquid leader which can suck (collect) an administration liquid into an appliance having a catheter tip (for example, a syringe, etc.), directly from the inside of an administration liquid housing container, such as, for example, a vial or ampoule, and can make this operation with ease and sureness. SOLUTION: The liquid leader 1 has a needle tube 2b having a needle tip 21b closed at its front end and a hub 3 fastened (fixed) to the base end of the needle tube 2b and is used by fitting the hub 3 to the front end of the catheter tip. The needle tip 21b is formed nearly to a conical shape and its flank is installed nearly oppositely with a pair of side holes 23b and 23b across a central axis 900. The hub 3 has a fitting part 31 of the inner diameter gradually increasing toward the base end. A pair of grooves 33 and 34 are formed in a flange part 32 in the positions corresponding to side holes 22b and 23b. The needle tube 2b is preferably composed of a thermoplastic resin. |
