The invention relates to a piercing system for removing bodily fluid from the skin of a human or animal. Said system comprises a disposable piercing unit (1), which contains a needle element (6) for puncturing the skin, a piercing device (2), which encompasses a piercing drive (4), said drive propelling a piercing displacement of the piercing unit (1), which is coupled to the piercing drive (4) by means of a coupling mechanism (3), a predefined value of the piercing depth being guaranteed using a piercing depth reference element (10), which comprises a skin contact surface (11) and the predefined value of the piercing depth being determined by the distance in the piercing direction between the skin contact surface (11) and the position of the needle tip at the inversion point of the piercing displacement. The piercing depth reference element (10) is connected to the needle element (6) and coupled to the drive in such a way that it is displaced together with the needle element (1) during at least one part of the propulsion phase and has a defined longitudinal position in the piercing direction in relation to the needle element (6), at least at the inverse point of the piercing displacement.

The invention relates to a blood collection system (1) for collecting blood for diagnostic purposes. Said system comprises an electric motor (9), which provides energy for propelling a lancet. According to the invention, the blood collection system also comprises a mechanical energy accumulator (20), in which the electric energy that is converted by the motor is stored in the form of mechanical energy. The use of a mechanical energy accumulator permits the use of known mechanical propulsion elements. The blood collection system can be electrically activated and is thus easy to use for the operator.
摘要:
A device for collecting samples of body fluids is described which has at least one lancet, comprising a lancet body and a tip. The device is characterized in that the lancet includes a structure of changed stiffness, which can also be referred to as a kinked area. This structure preferably has reduced stiffness compared to the rest of the lancet body, such that the lancet is preferably kinked in this area under the action of a force. As this happens, the tip is changed in orientation with respect to the rest of the lancet body. This change of orientation is preferably out of the plane of the lancet body.

A puncturing device comprising a band-shaped lancet carrier (2) carrying a plurality of lancets (3), a transport mechanism (6,7,8) for positioning the lancets (3) sequentially in a launch position by moving the band-shaped lancet carrier (2), a lancet drive (4) for accelerating a lancet (3) from the launch position for a puncturing movement, the lancet drive (4) comprising an energy storage (12) for providing energy for the acceleration of the lancet (3), a trigger element (10) for triggering the lancet drive (4), and a housing (5) which comprises at least two housing parts and encloses the band-shaped lancet carrier (2) and the lancet drive (4), the housing (5) having an opening (16), against which a body part is pressed for puncturing by a lancet (3). The puncturing device (1) is adapted for disposable use in that the housing parts were irreversibly connected upon enclosing the band-shaped lancet carrier (2) thereby sealing the band-shaped lancet carrier (2) irremovably in the housing (5).

The invention relates to a system for collecting samples and to a method for collecting a liquid sample. The system according to the invention for collecting samples comprises at least one analytical aid (1), wherein the analytical aid (1) comprises a lancet (3) and a test element (4), and the test element (4) has a test field (5) for analysis of the liquid sample. The system for collecting samples comprises a coupling element (7) which can be successively connected to the lancet (3), in a first position of the analytical aid (1), and to the test element (4), in a second position of the analytical aid (1). The system for collecting samples also comprises a drive unit (8) for moving the coupling element (7) from a rest position (22) to a deployed position, such that the movement of the coupling element (7) is transmitted to the lancet (3), coupled thereto, in order to execute a puncturing movement, or is transmitted to the test element (4), coupled thereto, in order to execute a sample-collecting movement.

摘要:
The inventive system for withdrawing body fluid contains a driving unit (100, 100') comprising a pusher (10, 110) which is moved out of a rest position, into a piercing position in order to carry out the piercing process; and a piercing unit (20, 120, 120') containing a lancet (30, 130, 130') with a needle. Said needle is located inside the piercing unit when the pusher is in the rest position. When the pusher is moved into the piercing position, the needle is displaced by the same in such a way that said needle at least partially exits through an outlet opening (41, 41') in the piercing unit. The pusher and the lancet are interconnected with a form fit in order to carry out the piercing process. The invention also relates to a method for temporarily moving a needle out of a device for withdrawing body fluid, and to a piercing unit for mounting on a driving unit.
