Abstract: A protector-attached puncture needle 10 in which a protector 14 is tiltably supported by a needle hub 18 of a puncture needle 12, and the protector 14 includes an accommodating groove 40 which opens toward the puncture needle 12 in a tilting direction and accommodates the puncture needle 12. Inner surfaces of both side walls 44, 44 of the accommodating groove 12 of the protector 14 include respective reinforcing ribs 52, 52 extending from a groove bottom portion toward a groove opening side. The reinforcing rib 52, 52 include respective recesses 54, 54 each opening to the inner surface of each of the side walls 44, 44. Diametrically both sides of an outer peripheral portion of a cap 30 enter and are locked in the respective recesses 54, 54 of the reinforcing ribs 52, 52 such that a tilt position of the protector 14 in an unused state before removal of the cap 30 is held.

Abstract: A novel blood collection instrument with which it is possible to prevent blood from coming into contact with air during collection of blood, and a blood collection plate that is suitably used therefor. A blood collection instrument including: a blood holding member having a structure in which a plurality of plate-shaped members, are overlapped with each other and including a collected blood holding passage formed between overlapped surfaces of the plate-shaped members; a connection part provided at an inflow port of the collected blood holding passage in the blood holding member; and a puncture member including a puncturing hollow needle while being connected to the connection part. An inner hole of the hollow needle of the puncture member is allowed to communicate with the collected blood holding passage in the blood holding member.
