Catheter assembly with guidewire, catheter and puncture needle

A catheter assembly comprising:

• a catheter possessing a proximal end portion, the catheter possessing a length;
• a catheter hub fixed to the proximal end portion of the catheter;
• a hollow inner needle including a distal end portion at which is located a needlepoint to puncture skin of a patient, the hollow inner needle being removably located in the catheter and possessing a length;
• a guide wire slidably positioned in the inner needle to be slidably movable in a forward direction, the guide wire possessing a central axis, the guide wire possessing a length, the length of the guide wire being longer than the length of the inner needle and longer than the length of the catheter, the guide wire possessing a distal end portion positioned proximal of the needlepoint during an initial state of the catheter assembly before the needlepoint punctures the skin of the patient and configured to project distally beyond the needlepoint after the needlepoint punctures the skin of the patient;
• a wire operating member which extends in a longitudinal direction, is displaceable in the forward direction relative to the inner needle and the catheter, and is connected to the guide wire so that displacement of the wire operating member in the forward direction results in movement of the guide wire in the forward direction, the wire operating member including a user-contacting surface that faces away from the guide wire and that is contacted by a user to apply a force to displace the wire operating member in the forward direction and thereby move the guide wire in the forward direction;
• a main body detachably connected to the catheter hub, the main body including a finger-engaging projection configured to be engaged by a finger of the user to advance the main body, the catheter hub and the catheter in the forward direction relative to the guide wire;
• the main body being rotatable about an axis relative to the catheter hub so that the main body, inclusive of the finger-engaging projection, is movable from a horizontal position in which the main body overlies the central axis of the guide wire towards a vertical position;
• and
• the finger-engaging projection of the main body being located distal of the axis about which the main body rotates when the main body is in the horizontal position in which the main body overlies the central axis of the guide wire.
