PROBLEM TO BE SOLVED: To provide a medical needle assembly which can prevent the exposure of a medical needle after storing it and can prevent an erroneous puncture while suppressing a burden on a subject.SOLUTION: A medical needle assembly includes: a needle body equipped with a needle tube having a needle tip at a distal end part and a columnar member which the needle tube penetrates and a housing for protecting the needle tip. The needle tube has the distal end part and a proximal end part, and the needle tube has a bent part which is curved or bent relative to a long axis of the needle tube at the distal end part. The columnar member is penetrated by a part from the bent part to a proximal end side of the needle tube, and the columnar member is stored in the housing in such a manner to be movable and not to be disengaged to the proximal end side. The housing has a through-hole the needle tube penetrates. The through-hole is formed in a position that deviates laterally from a position immediately below the needle tip and is configured to prevent the needle tip from protruding to the outside of the housing again once the needle tip is stored inside the housing from the outside of the housing through the through-hole.COPYRIGHT: (C)2015,JPO&INPIT【課題】被験者への負担を抑えつつ、収納後の医療用針の露出を阻止し、誤穿刺を防止することができる医療用針組立体を提供する。【解決手段】先端部に針先を有する針管と前記針管が貫通する柱状部材とを備える針体と、前記針先を保護する筐体とを有する医療用針組立体であって、前記針管は、先端部と基端部とを有し、前記針管の先端部は、前記針管の長軸に対して湾曲または屈曲したベント部を有し、前記柱状部材は、前記針管の前記ベント部から基端側の部分に貫通され、前記柱状部材は、移動可能かつ基端側への離脱不能に前記筐体に収納され、前記筐体は、前記針管が貫通する貫通孔を有し、前記貫通孔は、前記針先の直下から側方にずれた位置に形成されており、前記針先が前記貫通孔を通って前記筐体外から前記筐体内へ収納されると再度前記筐体外に突出しないように構成されていることを特徴とする医療用針組立体。【選択図】図1
