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 grip connected to the inner needle hub so that the inner needle hub, the inner needle and the elongated grip move together, the elongated grip projecting in the distal direction from the inner needle hub, 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;
- the elongated grip including a bottom and upstanding sides extending away from the bottom, the upstanding sides being spaced apart from one another so that a space exists between the upstanding sides, the inner needle and the hollow elongated outer member being located in the space;
- each of the upstanding sides of the elongated grip having an outer surface facing outwardly away from the space, the outer surface of each of the upstanding sides including a plurality of ribs spaced apart from one another along an elongated extent of the elongated grip to inhibit slipping of a user's hand that is gripping the elongated grip;
- a main body positioned in overlying relation to the inner needle, the main body being axially movable relative to the elongated grip and being connected to the outer member hub so that axial movement of the main body in a distal direction relative to the elongated grip results in axial movement of the hollow elongated outer member in the distal direction relative to the inner needle;
- the main body including at least one upstanding finger-engaging projection that is engageable by a user's finger to move the main body and the hollow elongated outer member relative to the inner needle, the at least one upstanding finger-engaging projection projecting away from the main body;
- and
- the plurality of ribs on each of the upstanding sides extending proximally beyond the at least one upstanding finger-engaging projection when the sharp needlepoint is exposed distally beyond a distal end of the hollow elongated outer member.
