摘要： A method involves positioning an assembled indwelling assembly adjacent a patient, wherein the assembly includes an inner needle, a hub fixed to the inner needle, a hollow outer member in which the inner needle is positioned, a hub fixed to the hollow outer member, and an elongated member axially overlapping an intermediate portion of the hollow outer member. The method also includes moving a distal portion of the assembly to puncture a blood vessel of the patient with the sharp needlepoint while the elongated member contacts the hollow outer member, advancing the hollow outer member in a distal direction along the inner needle to insert a distal portion of the hollow outer member to a target position in the blood vessel, and moving the inner needle hub in a proximal direction such that the inner needle is pulled out from and entirely removed from the hollow outer member.

摘要： An indwelling needle assembly includes a hollow outer needle, an outer needle hub fixed to a proximal portion of the outer needle, and an inner needle inserted in the outer needle. An inner needle hub is fixed to a proximal portion of the inner needle. A pressing member is connected to the outer needle hub, wherein the pressing member presses a portion of the outer needle between a proximal end and a distal end during a puncturing operation. The needlepoint of the inner needle and a distal portion of the outer needle, while in an assembled state, puncture a blood vessel in a process of placing the outer needle indwelling in a blood vessel.

摘要： A catheter assembly includes a catheter and an inner needle. The catheter has a catheter body and a flexible portion that is provided on a distal portion of the catheter body, includes a distal-most portion of the catheter, and is more flexible than the catheter body. The catheter body is made of a first material. The flexible portion is made of a second material. A change in flexibility of the second material between 25° C. and 37° C. is smaller than a change in flexibility of the first material between 25° C. and 37° C.
