Claim Text:
1. An indwelling assembly comprising: an inner needle having a sharp needlepoint at a distal end to puncture a blood vessel of a patient when the indwelling assembly is moved toward the patient, the inner needle possessing a proximal portion; an inner needle hub fixed to the proximal portion of the inner needle; a hollow elongated outer member in which the inner needle is positioned, the hollow elongated member being movable in a distal direction relative to the inner needle after puncturing the patient's blood vessel with the sharp needlepoint to position the hollow elongated outer member at a desired position in the blood vessel, the hollow elongated outer member possessing a proximal portion; an outer member hub fixed to the proximal portion of the hollow elongated outer member; first and second projections projecting from a main body section that is removably connected to the outer member hub, the first and second projections being configured to be engaged by a user to apply a force to the first and second projections causing the outer member hub and the hollow elongated outer member to move together with the first and second projections in the distal direction relative to the inner needle and the inner needle hub, the main body section being removably connected to the outer member hub so that the main body section is detachable from the outer member hub; an elongated movable member that is movable relative to the hollow elongated outer member and the outer member hub, the elongated movable member being connected to the inner needle hub so that the inner needle hub, the inner needle and the elongated movable member move together, the elongated movable member projecting in the distal direction from the inner needle hub; and the elongated movable member being movable together with the inner needle hub and the inner needle in a proximal direction relative to the hollow elongated outer member and the outer member hub after the hollow elongated outer member is positioned in the patient's blood vessel to remove the inner needle from the patient's blood vessel while the hollow elongated outer member remains positioned in the patient's blood vessel and to entirely remove the inner needle from the hollow elongated outer member.
