Abstract
A medical puncturing device for a so-called indwelling needle, includes: an indwelling needle composed of an indwelling outer needle element of a soft synthetic resin capillary tube and a puncturing inner needle element of a metallic capillary tube fitted through the outer needle element; and an outer sleeve for incorporating the indwelling needle. The indwelling needle has a projected part on the periphery at the rear end thereof while the outer sleeve has a guide slot cut along the axial direction on the peripheral surface thereof. The projected part is fitted through the guide slot and can move forward and backward so as to project and retract the indwelling needle with respect to the front side of the outer sleeve. The device further has locking arrangements in the front and rear ends of the guide slot so as to keep the indwelling needle at the projected and retracted positions.
