摘要： An objective of the present invention is to provide an indwelling needle assembly that has a novel structure and improves operability for the practitioner. An indwelling needle assembly 10 in which an inner needle unit 16 comprises a storage housing 14 for storing a protector 52, and which is provided with a connecting member 94 that connects the storage housing 14 to an outer needle hub 20. The protector 52 prevents movement of the connecting member 94 and holds the storage housing 14 and the outer needle hub 20 in a connected state. Deformation or displacement of the protector 52 due to retraction of an inner needle 12 permits the movement of the connecting member 94 and makes it possible to release the connected state between the storage housing 14 and the outer needle hub 20.

摘要： Provided is a medical valve of a novel structure, which is able to more reliably support an outer peripheral part of an elastic valve body with respect to a housing, and prevent a problem of the elastic valve body becoming dislodged inward. A medical valve (10) includes an elastic valve body (16) with annular grooves (76, 74) formed thereon and a tubular support part (70) formed at an outer peripheral side of an annular joining part (72) positioned between the annular grooves. Inside and outside holding parts (20, 18) engage the annular grooves (76, 74) provided to the valve inside and outside surfaces of the annular joining part (72). The outside holding part (18) and inside holding part (20) are provided to an opening member (12), and with the tubular support part (70), a part projecting inward in an axial direction (82) is sandwiched and supported between the inside holding part (20) and outside holding part (18).
