An insertion device including an insertion needle holder and a drive mechanism for linearly moving the insertion needle holder in a puncturing direction. The insertion needle holder also includes at least one actuating element for actuating a drive mechanism. The drive mechanism converts a driving motion of the actuating element, which extends transversely or opposite to the puncturing direction, into a puncturing motion of the insertion needle holder.

Insertion device

A lancing device comprises a lancet drive to cause a lancet to effect a puncturing movement, a housing that encloses the lancet drive, and a touching element with an opening for applying a part of a body in which a prick wound is to be produced, the touching element being movable relative to the lancet drive for the purpose of adjusting the puncturing depth in a puncturing direction. The touching element is connected rotatably by means of a screw thread to an intermediate piece and is movable in the puncturing direction, while the intermediate piece is rotatable and movable relative to the housing. A guide prevents rotation of the touching element relative to the housing, and the touching element is enclosed by the intermediate piece at least over part of its length.

The invention relates to a system for collecting samples and to a method for collecting a liquid sample. The system comprises at least one analytical aid, the analytical aid comprising a lancet and a test element, and the test element having a test field for analysis of the liquid sample. The system for collecting samples comprises a coupling element which can be successively connected to the lancet, in a first position of the analytical aid, and to the test element, in a second position of the analytical aid. The system for collecting samples also comprises a drive unit for moving the coupling element from a rest position to a deployed position, such that the movement of the coupling element is transmitted to the lancet, coupled thereto, in order to execute a puncturing movement, or is transmitted to the test element, coupled thereto, in order to execute a sample recovery movement.

An insertion device with an underside for placing on the skin of a patient, which has a recess for an insertion needle. The insertion device has means for forming a skin surface rising like a step or slope and facing towards the recess, preferably bearing on the recess. The means for forming the step or slope may include first and second pressure areas for pressing the skin with the recess for the needle located between the first and second pressure areas. The device may be configured whereby a downwardly extending cutting plane, in which the insertion needle lies, intersects the first pressure area in a first line and the second pressure area in a second line, and wherein the first line in the vicinity of the recess extends at a greater height than the second line. At least one of the two pressure areas may be a strip.

Method and device for puncture of insertion needle into subcutaneous fatty tissue

The present invention provides a puncturing system for withdrawing body fluid. The puncturing system comprises a disposable puncturing unit, which includes a needle element for piercing into skin and a puncturing depth reference element with a skin contact area. The system includes a puncturing instrument which has a puncturing drive, wherein the puncturing drive is coupled by a coupling mechanism to the puncturing unit for driving the needle element to a puncturing depth, the puncturing depth being determined by the distance in the piercing direction between the skin contact area and the position of the tip of the needle at a reversal point of the puncturing movement. The puncturing depth reference element is connected to the needle element such that the puncturing depth reference element moves with the needle element during at least part of the puncturing movement. The puncturing depth reference element has a defined longitudinal position in the piercing direction relative to the needle element at least at the reversal point of the puncturing movement.

Puncturing system for withdrawing a body fluid

The invention relates to a lancing system having a lancet carrier tape () supporting a plurality of lancets (), a transport means () serving to move the lancet carrier tape () in a feed or transport direction along a transport path and to thereby move lancets () of the lancet carrier tape () one after the other to a puncturing position, and a lancing drive () for causing a lancet () that occupies a puncturing position to perform a puncturing movement. It is provided according to the invention that during a puncturing movement the lancing drive () moves a lancet (), that has been brought to a puncturing position, in the puncturing direction together with a portion of the lancet carrier tape () on which that lancet () is supported and that once a lancet () has been moved to the puncturing position at least one element of the transport means (), arranged behind the puncturing position in the transport direction, performs a movement before or during the puncturing movement of that lancet ().

Lancing system

The present invention is generally directed towards the field of lancing aids in which disposable lancet systems are used. The lancet system according to the invention has a needle body which surrounds the needle tip in a lancet system in a protective manner and also comprises a protection against re-use of an ejected lancet system.
