Disclosed is an infusion system for administering a liquid medicament, particularly insulin. Said infusion system comprises a cannula support unit which is properly attached to a patient's body, an infusion cannula to be inserted into the patient's body, and a pump unit that can be connected to the cannula support unit and encompasses a pump, a battery for supplying power to the pump, and a storage volume for the medicament that is to be administered. The pump unit and the cannula support unit are adapted to one another in such a way that the pump unit rests against the cannula support unit once the pump unit has been connected to the cannula support unit. The disclosed infusion system also comprises a charging station for the pump unit in order to recharge the battery of the pump unit.

An actuator for driving a test element is disclosed. The test element can comprise a lancet for perforating the skin of a living organism. The actuator can comprise an engaging part for engaging and driving the test element in a lancing motion. The actuator can further comprise a lancing actuator and a lancing spring. The lancing actuator can bias the lancing spring by executing a forward movement and thereby can exert a biasing force on the engaging part. The actuator can further comprise a latch element. The latch element can be a force-sensitive latch element for exerting a retention force to hold back the engaging part. The retention force can counteract the biasing force. The latch element can release the engaging part when the biasing force exerted by the lancing actuator exceeds the retention force exerted by the latch element, thereby allowing the test element to perform the lancing motion.

A disposable diagnostic article comprising a lancing element that can be pierced into a body part and a collection area formed on the lancing element for body fluid obtained by the puncture is disclosed. The lancing element can comprise at least two bent parts folded towards each other such that the at least two bent parts can partially delimit the collection area.

The invention concerns a device for collecting body fluids which has at least one lancet comprising a lancet body with at least two tips of different lengths. The device is characterized in that it has a selection means with the aid of which only one tip is selected before the lancing. This selection means can have different functions and shapes. The selection means is used to select a tip from a plurality of lancet tips which have different lengths and make only this tip available for use in the lancing process. Since the various tips are attached to a lancet body, it is, for example, possible to use a bending element which bends one of the various tips out of the plane of the lancet body in order to provide only one lancet tip for use. This is especially preferable for lancet tips that are arranged linearly relative to one another.

A device for obtaining body fluid is described which has at least one lancet comprising a lancet body and a tip. The lancet has at least one structure with an altered stiffness which can also be referred to as a bending region. This structure preferably has a lower or reduced stiffness than the remaining lancet body such that the lancet can be bent in this region when a force acts thereon. In this process, the orientation of the tip is changed relative to the remaining lancet body. This change in orientation is preferably out of the lancet body plane.
