| description | 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. |
