PROBLEM TO BE SOLVED: To provide a Huber needle with a safety tube.SOLUTION: A Huber needle includes: a body including a hollow part that penetrates; a needle arranged inside the hollow part of the body; and a safety tube arranged along the needle. The safety tube extends along and around the needle inside the hollow part of the body at a first position, and the needle is exposed from the hollow part of the body; and at a second position, the safety tube extends along and around the needle extending from the hollow part of the body. A needle as long as a second length extending from a first end part of the hollow part of the body is wholly encircled by the safety tube and is provided with an engaging member which prevents the safety tube from coming off of the hollow part of the body when the safety tube is pulled out. The engaging member has a retaining ring, and another retaining ring in the hollow part of the body. The retaining rings interact in the way that they prevent the safety tube from separating from the body. |
