SINGLE-PUNCTURE LANCING SYSTEM

摘要

A lancing device comprises a main housing, a moveable housing and one or more contacting members. The main housing forms an inner cavity enclosing a portion of a lancing mechanism. The lancing mechanism includes a lancet holder attached to a shaft having an enlarged end. The main housing further encloses a drive spring surrounding a portion of the shaft. The lancing mechanism is adapted to move between resting, cocking and puncture positions. The movable housing is adjacent the main housing and moves from a resting position to a cocking position. The moveable housing forms an inner cavity enclosing a portion of the shaft of the lancing mechanism. The contacting member is enclosed within the lancing device. The contacting member has a damping pad and a stopper and engages a portion of the lancing mechanism when moved from the cocking position to the puncture position.
