Indwelling Assembly
First Claim
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 outer 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;
an elongated contact member possessing a surface and configured to contact an intermediate portion of the hollow elongated outer member located between proximal and distal ends of the hollow elongated outer member when the indwelling assembly is moved toward the patient to puncture the blood vessel of the patient with the sharp needlepoint of the inner needle;
an engaging section engaging the elongated contact member for restricting movement of the elongated contact member and possessing a surface that contacts the surface of the elongated contact member before the hollow elongated outer member is moved in the distal direction relative to the inner needle; and
the engaging section disengaging the elongated contact member while the hollow elongated outer member is moved in the distal direction relative to the inner needle so that the surface of the elongated contact member moves away from the surface of the engaging section.

Abstract
An indwelling assembly includes an inner needle having a sharp needlepoint, an inner needle hub fixed to the inner needle, a hollow elongated outer member in which the inner needle is positioned and movable in a distal direction relative to the inner needle after puncturing the blood vessel to position the elongated outer member at a desired position in the blood vessel, an outer member hub fixed to hollow elongated outer member, a projection removably connected to the outer member hub and configured to be engaged by a finger of the user to apply a force to the projection causing the outer member hub and the hollow elongated outer member to move together with the projection in the distal direction relative to the inner needle and the inner needle hub, and an elongated movable member that is movable relative to the hollow elongated outer member and the outer member hub.

8. 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 outer 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; an elongated contact member overlying at least a portion of the hollow elongated outer member and configured to contact an intermediate portion of the hollow elongated outer member located between proximal and distal ends of the hollow elongated outer member when the indwelling assembly is moved toward the patient to puncture the blood vessel of the patient with the sharp needlepoint of the inner needle; an engaging section that is separate from the elongated contact member and that includes a first part on one lateral side of the elongated contact member and a second part on an opposite lateral side of the elongated contact member to restrict lateral movement of the elongated contact member relative to the engaging section before the hollow elongated outer member is moved in the distal direction relative to the inner needle; and the elongated contact member being configured to move away from the hollow elongated outer member as the hollow elongated outer member moves in the distal direction relative to the inner needle. - View Dependent Claims (9, 10, 11, 12)
