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;
a main body section 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;
a cover section covering an upper side of the elongated movable member, a part of the main body section being disposed under the cover section;
the outer member hub being disposed in an area between the elongated movable member and the cover 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.

9. 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 so that the inner needle and the inner needle hub move together as a unit; 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 so that the hollow elongated outer member and the outer member hub move together as a unit; an elongated movable member connected to the inner needle hub so that movement of the elongated movable member results in movement of the inner needle hub and the inner needle, the elongated movable member including two spaced apart side portions projecting upwardly away from a bottom portion so that the two side portions and the bottom portion together define a space, the elongated movable member projecting in the distal direction from the inner needle hub, the inner needle being positioned in the space before puncturing the patient'"'"'s blood vessel, a main body section connected to the outer member hub so that the main body section and the outer member hub move together, the main body section being detachable from the outer member hub, a part of the main body section overlying the outer member hub; a cover section overlying a part of the space in the elongated movable member and also overlying a section of the main body section positioned in the space so that the section of the main body section is positioned between the bottom portion of the elongated movable member and the cover section; and a portion of the main body section being uncovered by the cover section before puncturing the patient'"'"'s blood vessel so that the portion of the main body section is engageable by a user'"'"'s finger to move the hollow elongated outer member in the distal direction relative to the inner needle after puncturing the patient'"'"'s blood vessel to thereby position a distal end of the hollow elongated outer member distally beyond the sharp needlepoint. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
