摘要：<P>PROBLEM TO BE SOLVED: To provide an indwelling needle assembly in which the hole of a sealing member can be surely closed in such a state that the indwelling needle assembly is disassembled. <P>SOLUTION: The indwelling needle assembly 1 is provided with: an inner needle 4; an inner needle hub fixed to the proximal end of the inner needle 4; an outer needle 2 which the inner needle 4 is put through; an outer needle hub 3 fixed to the proximal end of the outer needle 2; a sealing member 8 movably provided inside the outer needle hub 3 and having a slit 81 which the inner needle 4 can be put through; and a protector for covering the inner needle 4. The indwelling needle assembly 1 assumes two states, i.e., the assembling state where the inner needle 4 is put through the outer needle 2 and the sealing member 8, and the disassembling state where the inner needle 4 is pulled out from the outer needle 2 and the sealing member 8. The indwelling needle assembly 1 includes: a compression coil spring 40 for energizing the sealing member 8 in a proximal end direction; the projecting part 916 of the protector 9 for restricting the movement of the sealing member 8 in the proximal end direction against the energizing force of the compression coil spring 40 in the assembling state; and a compression member 30 for compressing the sealing member 8 in the diametrical direction, which is moved in the proximal end direction after restriction by the projecting part 916 is released, in the disassembling state. <P>COPYRIGHT: (C)2007,JPO&INPIT
