<P>PROBLEM TO BE SOLVED: To provide a puncture instrument which stably and reliably punctures a skin layer with a puncture needle. <P>SOLUTION: The puncture instrument 1 punctures the skin (dermis D) with the puncture needle 5. The puncture instrument 1 is provided with: a slide member 4 holding the puncture needle; a base part 2 movably supporting possible the slide member 4; and a skin deformation member 3 which has a first flat plate part 31 rotatably attached to the base part 2, a second flat plate part 32 sliding guided by the base member 2 and a connection part 33 for connecting the first flat plate part 31 with the second flat plate part 32, and which is adhered to the body surface F. The skin deformation member 3 is rotated to be displaced to the upper side of the second flat plate part 32 to raise the skin, and a puncture needle holding member 4 is moved to puncture the raised skin with a puncture needle 5 through an opening window 23 formed at the base member 2 and a through hole 331 formed at the connection part 33. <P>COPYRIGHT: (C)2007,JPO&INPIT |
