Claim 0:
1. A catheter assembly comprising:
a hollow catheter;
a catheter hub to which the catheter is fixed;
an inner needle including a needle tip, the inner needle being detachably disposed inside of the catheter;
a needle hub to which the inner needle is fixed;
a catheter operation member configured to move the catheter relative to the inner needle; and
a support member attached to the needle hub and configured to rotate about a rotation axis orthogonal to a longitudinal direction of the assembly, wherein:
the support member comprises a support main body portion that projects in a direction orthogonal to the rotation axis of the support member and that is movable relative to the needle hub between (i) a first position at which the support main body portion contacts and supports the catheter, and (ii) a second position that is a different position from the first position, at which the support main body portion does not contact the catheter,
the support member is configured to remain attached to the needle hub when the inner needle is fully detached from the catheter;
when the support member is at the first position, the support main body portion projects in a direction orthogonal to a moving direction of the catheter, and
when the support member is at the second position, the support main body portion projects in a moving direction of the catheter operation member relative to the needle hub.
