    摘要： The present disclosure relates to a blood collection device, including: a shell; a blade seat, arranged in the shell; an elastic component for providing an elastic force for pivoting the blade seat; a triggering portion, including an operating end and an abutting end, wherein the triggering portion has a first position and a second position for pivoting, the operating end extends to the outside of the shell, the abutting end is located in the shell, based on the operation of the operating end, the triggering portion is suitable for pivoting from the first position that prevents the blade seat from pivoting to the second position that allows the blade seat to pivot based on the elastic force of the elastic component, wherein: a cooperation column is arranged in the shell and is located at the upper side of the triggering portion spaced from the triggering portion; and an elastic arm is connected to the upper side of the triggering portion, the end part of the elastic arm includes a blocking portion, the end part of the elastic arm is suitable for being located on one side of the cooperation column when the triggering portion is at the first position, and is located on the other side of the cooperation column when the triggering portion pivots from the first position to the second position, and the blocking portion provides resistance for the end part of the elastic arm while moving from one side of the cooperation column to the other side.

    摘要： The medical puncturing device includes a housing, a shield, and a skin puncturing assembly disposed within the housing. The shield is axially movable in the housing. The skin puncturing assembly includes a movable carrier and a skin puncturing element mounted to the carrier. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed. The carrier is maintained in the retracted position by engagement of flexure members or a retaining tab with the carrier. A drive spring is provided to move the carrier from the retracted position to the puncturing position. A retraction spring is provided to return the carrier and skin puncturing element into the housing.
