    • PROBLEM TO BE SOLVED: To provide a needle assembly which can block exposure of a used needle and prevent body fluid from scattering.SOLUTION: A needle assembly includes a needle body and a needle prevention member provided at a proximal end part of the needle body. The needle protection member has a pair of slices facing each other with an axis of the needle body therebetween, and at least one of the pair of slices has, around it, an engagement part engaged with the other slice. When the engagement part is engaged with the other slice, the pair of slices form a bag shape and store the needle body inside. Thus, since the needle body is not exposed after use, false puncture can be prevented and scattering of body fluid can be prevented as well.
    • 要解决的问题:提供一种能够阻挡使用过的针的暴露并防止体液飞散的针组件。解决方案:针组件包括设置在针体的近端部分的针体和针防止部件。 针保护构件具有彼此面对的一对切片,其中针体的轴线在其间,并且该对切片中的至少一个具有与另一切片接合的接合部。 当接合部分与另一个切片接合时,这对切片形成袋状并将针体存储在内部。 因此,由于针体在使用后不露出,因此能够防止假刺穿,并能够防止体液的散射。
