CATHETER ASSEMBLY AND CATHETER INDWELLING BODY

摘要

A catheter assembly (10) and a catheter indwelling body (22) include an inner needle (14), a catheter (12), and a catheter hub (20). Further, the catheter assembly (10) also includes a valve (24) having a slit (64); and an opening member (26) that is provided in an internal space (50), is formed in a tubular shape with a space portion (74) inside, is located closer to a proximal side than the valve (24) in an initial state, and opens the valve (24) by moving in a distal direction. The opening member (26) has a side hole (80) that causes a space portion (74) to communicate with the outside of the opening member (26), and the side hole (80) is located closer to a distal side than the most proximal end of the slit (64) in a state where the valve (24) is opened.
