A lancet pricking device comprises a lancet, a launching spring, a trigger part and a holder housing the lancet, launching spring and trigger part. 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 toward the inside of the holder before the lancet cap is removed, but can be pushed toward the inside of the holder after the cap is removed. The lancet body warps when pressed to release the secured lancet body.

Lancet pricking device

A lancet pricking device comprises a lancet, a launching spring, a trigger part and a holder housing the lancet, launching spring and trigger part. 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.

A lancet includes a lancet body having a distal end portion of a puncturing member protruding from the front end portion thereof, and a cap that houses and protects the distal end portion of the puncturing member that protrudes before use, wherein the front end portion of the lancet body and the rear end portion of the cap are integrated in substantially adjoining state with each other via a weakened portion. One of the end face at the front end portion of the lancet body and the end face at the rear end portion of the cap that opposes the former has protrusions, and the top ends of the protrusions define an imaginary plane that extends perpendicularly to the longitudinal direction of the puncturing member, and the other end face defines the flat surface that extends perpendicularly to the longitudinal direction of the puncturing member.
