Claim 3:
4. 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, (ii) a second position that is offset from the first position in an advancement direction of the catheter operation member relative to the needle hub, at which the support main body portion does not contact the catheter, and (iii) a third position that is offset from the first position in a retraction direction of the catheter operation member relative to the needle hub, at which the support main body portion does not contact the catheter, and
the support member is configured to remain attached to the needle hub when the inner needle is fully detached from the catheter.
