发明名称 Lancet device
摘要 The lancet device includes a housing and a lancet having a puncturing element. The lancet is disposed within the housing and is adapted for axial movement between an initial or pre-actuated position wherein the puncturing element is retained within the housing, and a puncturing position wherein the puncturing element extends through a forward opening in the housing. The lancet device includes a drive spring disposed within the housing for biasing the lancet toward the puncturing position, and a retraction or return spring for returning the lancet to a position within the housing where the puncturing element is disposed within the housing. The retraction spring thereafter maintains engagement with the lancet to assist in preventing the puncturing element from again projecting outward from the forward opening in the housing.
