To ensure a safe stop, It is advantageous if the stop bead from the free outer edge the compression element tapers away preferably wedge-shaped.
alternative or in addition it is also possible that the carrier part an opening to impress of the compression element, and that on the housing side of the support member one in the opening area projecting abutment for limiting the Eindrücktiefe the compression element is appropriate. For a safe support is it cheap when the abutment through one in the opening of the support member tapering into it Stop ring is formed.
For one preferably deep-reaching engagement, it is advantageous if the compression element with an opening edge the carrier part is firmly connected, wherein the connecting surface over the entire height of the opening edge extends so that the invagination as deep as possible during compression in the housing area he follows.
In order to optimize the introduction of force, it is advantageous if the interface between Carrier part and compression element is remote as a slope of a housing-side boundary surface of the support member, wherein the angle between the slope and the boundary surface should be in the range of 50 ° to 70 °, preferably at 60 °.
For the compression process it is also advantageous if the compression element in the initial state one on a housing side Edge of the carrier part kink-free tapered inner surface having.
to improved adaptation to a domed body contour and secure Liability, it is advantageous if the engagement part through the inner edge a concave arched ring surface the compression element is formed.
production engineering is it cheap if the compression element as a molded part, preferably as an injection molded part formed on the prefabricated carrier part is. In this case, the compression element via a particular by a primer formed adhesive bond are attached to the support member.
advantageously, the compression element consists of silicone, rubber or polyurethane. Out hygienic reasons Silicone is preferably used.
In structurally advantageous embodiment is the carrier part formed as a dimensionally stable annular disc, in particular made of metal.
A single stage production leaves be realized by that of a thermoplastic elastomer existing compression element and the existing plastic support part are formed as a two-component injection molded part.
Around an exchange, for example, to adapt to the body part size or To allow for cleaning, the support member is detachable in a housing receptacle used.
For a compact Type of handset is it cheap if the total width of the carrier part perpendicular to the pressing direction less than 25 mm, preferably less than 20 mm.
In procedurally the object mentioned is achieved in that the body part when pressed in the case penetrates into it, with a removal area of the body part inside the case for one liquid withdrawal is kept free. The impression depth of the compression element is preferred limited by slings.
in the The invention will be described below with reference to the drawing illustrated embodiments explained in more detail. It demonstrate:
1 a portable analyzer for blood sugar determination with a device for finger positioning in perspective view;
2 and 3 the removable from the device positioning device in a perspective view and in axial section;
4 the positioning device with pressed finger for applying a test element in axial section; and
5 another embodiment in one 3 corresponding representation.
The positioning device shown in the drawing 10 is in the case 12 a portable blood glucose meter 14 can be used to get a fingertip 16 a subject in the device interior 18 to position for blood collection and analysis.
For this purpose, the in 1 shown handset 14 on a front side a recording 20 for the replaceable positioning device 10 on. The device comprises as an integrated system a lancing device for puncturing the fingertip and an analysis device for determining the sugar content of the blood taken at the puncture site (not shown). The result he averages over a display unit 22 for the user.
How best 2 and 3 can be seen, the positioning device 10 a flexible compression element 24 for pressing the finger berry 16 and a dimensionally stable carrier part 26 for holding the compression element 24 on. The annular in cross-section compression element 24 has two in the direction of the Andrückachse 28 conically converging sections 30 . 32 , The kink between these parts 30 . 32 forms one for the engagement of the finger-berry 16 open engagement 34 , which in the Andrückbewegung their clear width in the opening area 36 and thus squeezing the free finger tip with pressure increase to promote the blood accumulation.
For better adaptation to the finger contour has the upper or distal portion 30 a concave inner ring surface 38 on. This results when pressing the finger 16 first a circular edge contact in the area of the engagement part 34 with high surface pressure for non-slip positioning.
To stop the pressing movement reliably, is at the free outer edge of the distal portion 30 a stop bead 40 formed, extending to the proximal portion 32 tapered wedge-shaped. The stop bead 40 is supported in the stop position on the outside 42 of the subarea 32 and thus prevents further folding of the compression element 24 in the direction of pressure.
The carrier part 26 limited as an annular disc a passage opening 44 for the compression element 24 , At its opening edge 46 is the carrier part 26 over its entire height or wall thickness by means of adhesive connection firmly with the compression element 24 connected. For a favorable force introduction is the connection surface 48 as a slope at an acute angle of about 60 ° relative to the housing-side boundary surface 50 arranged the carrier part. In order to achieve a large indentation depth, the inner surface runs 52 of the proximal portion 32 with a smooth contour kink-free on the housing side edge of the opening edge 46 to.
The compression unit 24 is formed as a flexible molding of silicone, while the support part 26 made of metal, preferably aluminum. The compression element can be molded by injection molding on the inserted into an injection mold carrier part, wherein a primer on the connection surface 48 increases the strength of the adhesive bond. Alternatively, a production in the two-component injection molding process is conceivable, wherein the compression unit 24 made of a thermoplastic elastomer and the carrier part 26 be molded from plastic in one operation as a composite part.

Due to the deep connection of the proximal portion 32 at the opening edge 46 becomes the kink 54 shifted accordingly in Andrückrichtung down. The engagement party 34 thereby extends into the interior 18 of the housing 12 and at least under the housing-side boundary surface 50 the carrier part 26 , Accordingly, a removal area 56 the fingerberry 16 inside the case 18 exposed. After the puncture can thus an escaping blood drop 58 free through a flat test field 60 be removed without a punctual access would be required. This type of automatic blood collection is particularly suitable in combination with a tape cassette system, with a variety of on a carrier tape 62 stored test fields 60 successively in the engagement area of the body part 16 can be transported.
At the in 5 shown embodiment, like parts are provided with the same reference numerals as above be written. In addition, here is an abutment 64 provided on the housing-side boundary surface 50 the carrier part 26 is appropriate. The abutment 64 protrudes to limit the indentation depth of the compression element 24 in the area of the opening 44 into it. Here is the abutment 64 beveled downwards in the opening area to a free peripheral edge, so that one to the inner surface 52 of the compression element 24 counter-beveled abutment surface 66 arises for a positive support. As a result, an additional positioning accuracy of the fingertip 56 reached for the blood collection inside the device.
