PROBLEM TO BE SOLVED: To provide a medical needle assembly preventing erroneous puncture by preventing the exposure of a needle after use while suppressing a load on an affected part.SOLUTION: A medical needle assembly includes: a needle body having a needle tube and a needlepoint inclined to the long axis of the needle tube and a needlepoint protective member slidably provided to the needle tube. The needlepoint protective member has: a base end part having a through-hole through which the needle body is inserted and a beam member cantilever-supported in an edge part of the base end part, and extending toward the distal end from the base end part. A distal end part of the beam member is formed with a bottom part extending to the direction of the needle body. Thereby, the exposure of a needle after use is prevented while suppressing a load on an affected part, and erroneous puncture can be prevented.COPYRIGHT: (C)2014,JPO&INPIT【課題】患部への負担を抑えつつ使用後の針の露出を阻止し、誤穿刺を防止できる医療用針組立体を提供する。【解決手段】本発明の医療用針組立体は、針管と、前記針管の長軸に対して傾斜した針先とを有する針体と、前記針管に摺動自在に設けられた針先保護部材とを備える。前記針先保護部材は、前記針体が挿通される通孔を有する基端部と、前記基端部の縁部に片持ち支持され、前記基端部から先端に向かって延出するはり部材とを有し、前記はり部材の先端部には、前記針体の方向へ延出する底部が設けられている。これにより患部への負担を抑えつつ使用後の針の露出を阻止し、誤穿刺を防止することができる。【選択図】図1
