摘要:
Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid, and the device further comprising a fluid receiving means remote spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially. The collection zone takes up a very small volume of body fluid of about 10 to 500 nl in a very short time period of less than 0.5 seconds. The fluid receiving means may have a test zone for performing an analytical reaction. Fluid sample from the collection zone is automatically or manually transported to the fluid receiving means to contact the fluid with the test zone.

Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid. In one embodiment, the collection zone includes a plurality of holes, e.g., 3 or more holes, or 50 to 100 holes. The hole size may be small, e.g., having a diameter of 0.01 to 0.5 mm. The holes may or may not extend through the lancet. In some embodiments, the holes have a depth of 50 to 500 μm. In other embodiments, the collection zone is porous, or is a roughened area. The collection zone can take up a very small volume of body fluid, e.g., 3 to 10 nL, in a very short time period, e.g., less than 0.5 seconds. In other embodiments, the device further comprises a fluid receiving means spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially.

Lancing system comprising a needle and a lancing device The lancing device comprises a housing with a housing opening that is surrounded by a housing skin contact surface. A lancing depth reference element with a reference skin contact surface is adapted in such a manner that the reference skin contact surface at a reversal point of the lancing movement is in contact with the skin. The lancing depth is determined by the distance between the reference skin contact surface and the tip of the needle element at the reversal point of the lancing movement. The lancing depth reference element is in a stationary defined position relative to the reversal point of the lancing movement. The lancing depth reference element is adapted to stabilize the skin when pressed against the reference skin contact surface with respect to a skin deformation which occurs upon lancing of the skin.

Lancing system for extracting a body fluid from the skin of a human or animal comprising a needle element (3) for lancing the skin, a lancing device (2) which includes a lancet drive (15a), by which a lancing movement of the needle element (3) coupled with the lancet drive by means of a coupling mechanism (28) is driven in lancing direction, wherein the lancing device (2) comprises a housing (4) with a housing opening (5) at its in lancing direction front end and the housing opening (5) is surrounded by a housing skin contact surface (7) which is pressed against the skin when using the lancing device (2), the needle element (3) is moved on a predetermined lancing path in a lancing direction in a forward phase of the lancing movement until its tip (3c) enters the skin in order to create a wound and in a return phase of the lancing movement following the reaching of a reversal point corresponding to the lancing depth (S) in the skin is retracted again, a lancing depth reference element (8) with a reference skin contact surface (11) is provided to improve the reproducibility of the lancing depth (S), which is adapted and arranged in such a manner that the reference skin contact surface (11) at the reversal point of the lancing movement is in contact with the skin and the predetermined value of the lancing depth (S) is determined by the distance in lancing direction which prevails at the reversal point of the lancing movement between the reference skin contact surface (11) and the position of the tip (3c) of the needle element (3), at which at the time at which the tip (3c) of the needle element (3) in the forward phase of the lancing movement passes the reference skin contact surface (11) and enters a skin surface which is in contact with said reference skin contact surface, the lancing depth reference element (8) with the reference skin contact surface (11) is in a stationary defined position relative to the reversal point of the lancing movement and the lancing depth reference element (8) is adapted and arranged in such a manner that the skin when pressed against the reference skin contact surface (11) is stabilized with respect to a skin deformation which occurs upon lancing of the skin.
摘要:
A system comprising disposable medical devices and a packaging strip comprising a plurality of chambers containing the disposable medical devices. The strip is folded along breadthwise running fold lines to form a series of loops, each loop comprising opposing sections. The opposing sections of at least some of these loops are sealed to each other thus forming chambers between said sections. A cartridge contains such a packaging strip.

Catheter for monitoring the concentration of an analyte in a body fluid having an implantable distal area (7) for the uptake of body fluids and a proximal area (8) with an outlet opening (14), wherein the catheter comprises a catheter casing (1) having microopenings which are permeable to at least part of the body fluid and at least partially hold back corpuscular components, and a catheter core (2) which is located in the catheter casing (1). The catheter core preferably has a microstructure on its peripheral surface and/or the catheter casing has a microstructure on its inner wall which form a hollow space between the catheter core and catheter casing. Moreover the invention concerns a method for the manufacture of such a catheter.

An introducing device for introduction of a medical device into a body is described which has a distal region with a tip region for generating an opening in the skin, and a segment region which comprises at least two sections which, in a rigid state, are essentially rigidly connected at least to one another and to the distal region and which are movable relative to one another in a flexible state. Furthermore, a system is described in which a sensor is integrated into the device for introduction into a body.
