A catheter assembly includes: a catheter; a catheter hub; an inner needle; a needle hub; and a deflection suppressing mechanism suppressing deflection of the inner needle. The deflection suppressing mechanism includes an upper deflection suppressing portion positioned on an upper side of the inner needle and a lower deflection suppressing portion positioned on a lower side of the inner needle. At least one of the upper deflection suppressing portion and the lower deflection suppressing portion is movable with respect to the needle hub.

Catheter assembly

A catheter includes: a first port; a second port; a first lumen communicating with the first port; a second lumen configured to selectively communicate with the first port and/or the second port; and a switching mechanism part selectively switchable between a first switching state in which the first port and the second lumen communicate with each other and a second switching state in which communication between the first port and the second lumen is blocked.
