The present invention relates to a vein indwelling needle, with a storage cylinder for housing the tip of the withdrawn inner needle, to provide an indwelling needle Ayamatoge prevention has been subjected. An indwelling needle 10 includes a trocar outside the needle hub 12, the trocar 11, and the inner needle 14, and the storage cylinder 16, and Harigaiharimoto 18, a. And the through hole 161 in the storage cylinder 16, the elastic portion 15, a pasting Chakuban 17, is arranged. When the inner needle 14 is withdrawn from the trocar outside the needle hub 12 and trocar 11, the distal end of the inner needle 14 is accommodated in the accommodating cylinder 16 by the elastic section 15 and the attaching plate 17, a situation in which the distal end portion of the inner needle 14 is exposed To prevent. According to the indwelling needle 10 Ayamatoge prevention of one embodiment of the present invention has been performed, the grip portion 141 of the inner needle 14 is formed in the shape of a flat plate.FIELD 1【課題】静脈留置針に関し、引き抜かれた内針の先端部を収納するための収納筒を備えた、誤刺予防が施された留置針を提供する。【解決手段】留置針10は、トロッカー外針基12と、トロッカー11と、内針14と、収納筒16と、針外針基18と、を有する。収納筒16には貫通孔161と、弾性部15と、貼着板17と、が配置される。内針14がトロッカー外針基12及びトロッカー11から引き抜かれると、内針14の先端は弾性部15及び貼着板17によって収納筒16に収納され、内針14の先端部が露出する事態を防止する。本考案の一実施例の誤刺予防が施された留置針10によれば、内針14のグリップ部141が平板状に形成される。【選択図】図1
