PROBLEM TO BE SOLVED: To prevent a wrong operation in which only a stopper is removed without storing an inner needle into a shield after puncture, and to reduce the necessity of changing the holding position both in puncture and in storing the inner needle into the shield.SOLUTION: A hub 40 can be displaced between an initial position where the hub 40 is located at the front end side of the lumen of the shield 20 with the inner needle 50 penetrating an outer needle 30, and a retracted position where the hub is located at the rear end side of the lumen of the shield with the inner needle stored inside the lumen of the shield. A stopper 170 includes an insertion part 172 to be inserted into the lumen of the shield, and a base part 180 provided at the rear end of the insertion part. The base part includes a roof part 183 for exposing a part of the outer peripheral surface of a tube 60 connected to the hub while covering the rest of the outer peripheral surface, and a pair of holding parts 185 that is disposed across the tube and elastically displaced to hold the tube.

PROBLEM TO BE SOLVED: To allow real-time measurement of concentrations of components of a liquid including water in a region of infrared rays and to improve the measurement accuracy.SOLUTION: An instrument 30 for component measurement includes a flow passage forming unit 31 which forms a flow passage 34 connected to circulation tubes 18a and 18b where a liquid is circulated. The flow passage forming unit 31 is provided with an infrared irradiation unit C irradiated with infrared rays. A cross section dimension d1 in an infrared irradiation direction of a portion corresponding to the infrared irradiation unit C of the flow passage 34 is set shorter than an inner diameter d2 of the circulation tubes 18a and 18b. The flow passage 34 is provided with a bypass part 34d which bypasses a part of the liquid to avoid the portion corresponding to the infrared irradiation unit C of the flow passage 34.
