BLOOD COLLECTION SYSTEM FOR COLLECTING BLOOD FROM BODY PART FOR DIAGNOSTIC PURPOSE

摘要

PPROBLEM TO BE SOLVED: To prevent repeated puncturing of a body part by a lancet. PSOLUTION: This blood collection system comprises a housing 2 having a lancet guide 3 guiding a lancet 8 onto a predetermined puncture path, and a lancet drive 4 driving a puncturing movement of the lancet on the predetermined puncture path. The puncturing movement comprises a forward movement phase in the direction of puncturing and, after reaching a reversal point, a subsequent retraction movement phase. The lancet drive has a driving spring 5, which is connected to the lancet so that the lancet is driven in the puncturing direction. The system comprises an oscillation control device for controlling oscillation of an oscillatory system which comprises the lancet and the driving spring, in such a manner that its oscillation is altered to prevent repeated puncturing of the body part by the lancet.
