The lancet comprises a lancet body, lancet cap and pricking needle. The pricking needle is in both the lancet body and lancet cap. The trigger part has a pair of arms positioned inside the holder. The launching spring is attached to the lancet body. The lancet body is secured to the arms of the trigger part by an abutment of the lancet body on the arms such that the launching spring is compressed before a pricking operation. The trigger part cannot be pushed further into the holder before the lancet cap is removed, but can be pushed further into the holder after the cap is removed. The pair of arms warp when pressed to release the secured lancet body.

Abstract: A lancet assembly includes a lancet, a lancet engaging part, and a lancet case housing the lancet and the lancet engaging part. In the lancet assembly of the present invention, the lancet engaging part and the lancet cap are disposed such that they are capable of making contact with each other. When the lancet engaging part is forced to move forward with respect to the lancet in a pricking direction, the lancet cap is pressed by the lancet engaging part, and thereby the bridging component is broken so that the lancet cap is separated from the lancet body. When the lancet engaging part is forced to further move forward, the separated lancet cap moves to the position off a pricking pathway of the pricking component within the lancet case.
