摘要： An indwelling needle includes: a container barrel having a retraction mechanism (an actuator and urging element etc.,) for retracting the inner needle after use; and an outer needle support lid element for prohibiting the outer needle from being withdrawn into the container barrel. The outer needle support lid element has a gutter-like portion, which is a short cylinder formed in part with a cutout portion with its inside dimension designed so as to allow the inner needle to pass therethrough and be smaller than the outside dimension of the needle base (more exactly, the outer dimension of the flange of the needle base) of the outer needle.

摘要： A holder sleeve (1) incorporates an urging means (8) for urging an inner needle (12) to the proximal end side and an actuator (6) which engages the inner needle (12) at the near distal end portion of the holder sleeve (1) so that the inner needle (12) can be released and the tip of the inner needle is projected from the holder sleeve (1). This actuator (6) has an inner needle hub (12a) fixed at the front end thereof and is formed with an actuating member (6a) projected outside the holder sleeve (1). The holder sleeve (1) has a slit (2) which extends to the proximal end side so as to allow the actuating member (6a) of the actuator (6) to slide and assures the path of movement of the actuator (6) released from the near distal end portion of the holder sleeve (1). The inner needle (12) is adapted to be released from the holder sleeve (1) when the actuating member (6a) is moved away from the holder sleeve (1) within the same plane that includes the axis of the holder sleeve (1).

摘要： The mechanism includes: an urging means for urging an inner needle (12) to the side opposite to an outer needle (11) with respect to the axial direction of a holder sleeve (1) for holding the inner needle (12); an actuator (6) which is positioned between the urging means (8) and inner needle (12), moves together with the inner needle (12) and has a puncture position retainer for keeping the inner needle (12) and outer needle (11) ready for puncture and an inner needle retraction actuating portion for allowing for the retraction actuation of the inner needle (12); and a slit (2) for assuring the path of movement of the actuator (6). The puncture position retainer has a puncture position engagement portion whereby the actuator (6) is engaged with the holder sleeve (1) at a position on the outer needle side (11). The inner needle retraction actuating portion includes: an actuating portion (6a) for releasing the actuator (6) from the engaged state of the puncture position engagement portion into the urged state by the urging means (8) and an actuator housing for enclosing the actuator after retraction of the inner needle.

摘要： 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.
