Method for producing combined lancing and measuring devices for detecting an analyte in liquid, comprising a carrier (1) and a detection element (22), with the following method steps:
- the creation of piercing tips (16) defining recesses (11) on an end face (9) of the band-shaped carrier material (1),
- The application of a detection element (22) on the band-shaped carrier material (1) and
The individual or packet-wise separation of individual SMD base bodies (6) from the strip-shaped carrier material (1) at parting lines (5, 24, 25).
The The present invention relates to methods of preparation a piercing and measuring device and to such a device, in particular for the detection of analytes from body fluids.
In The rule today are test strips or sensors for single use for the detection of analytes from body fluids separated from lancets and lancing devices.
Out US 3,822,461 For example, a disposable lancet is known to pierce human skin to maintain a volume of blood. The lancet according to this solution is such that minimal material consumption is achieved during its production and consequently low production costs are achieved. The shape of the lancets for single use allows to punch out several lancets from a strip of material to ensure economic manufacturability. According to the in US 3,822,461 In the disclosed method, in which individual lancets are obtained with a piercing portion at one end of a metal strip and a shoulder formed thereon, the respective single lancet is punched out of a strip of material. The width of the material strip essentially corresponds to the length of the lancet. The lancets are punched out of the strip alternately, the tip of each lancet pointing in one direction and the single lancet to be punched next to it points in the other direction. For each punching operation, individual lancets are obtained whose outer contour is defined by the punching tool. Each of the punched-out lancets includes an elongated recess which extends from the handle end to the lancing end of the lancet and stiffens it so as to increase sufficient rigidity and bending safety for each lancet punched out of the continuous strip so that it does not kink in use.
Furthermore, it is off DE 197 53 847 A1 an analytical test element with capillary channel has been disclosed. This analytical test element serves to determine an analyte in a liquid and comprises an inert carrier, a detection element and a channel suitable for capillary liquid transport. This has a sample introduction port at one end and a vent at the other end. The suitable for capillary liquid transport channel is at least partially formed by the carrier and the detection element. The channel capable of capillary liquid transport extends from the sample introduction opening at least as far as the edge of the detection element closest to the vent opening. There is a recess in a surface forming the capillary liquid transport channel at the edge of the test element forming the sample application opening. As a result, the edge of the test element forming the sample application opening is at least partially interrupted on one side, the surface lying opposite the recess being exposed. At least one of the surfaces forming the inner surface of the channel suitable for capillary liquid transport is hydrophilized. This is achieved either by the use of a hydrophilic material or by coating a less hydrophilic material with a hydrophilic layer. For example, a layer of oxidized aluminum is suitable for hydrophilization.
According to the DE 197 53 847 A1 known solution is glued a double-sided tape. This contains a punch of a few millimeters wide and a few millimeters in length, by which the dimension of the capillary channel is defined. On the tape, a detection film is glued, which is designed for example specifically for the detection of glucose. The detection film covers the central, notch-shaped recess of the adhesive tape. On the exposed area of the adhesive tape, a cover layer is adhered, so that the cover layer and detection film abut each other. The cover layer is a laminate of thicker, stable plastic film and thin hydrophilic AluO x layer. The hydrophilic layer must protrude into the gap between the cover layer and the detection film. When mounting the cover layer on the adhesive tape, it is necessary to arrange the protruding end of the thinner film, ie, the thin hydrophilic AluO x layer, between the detection element and the thicker film of the cover layer. In such a manufacturing method, errors may occur because of the large number of gluing operations to be performed with great precision. Due to the process steps to be followed, this method is relatively time consuming.
US 6,102,927 A refers to a lancet and its manufacturing process. The lancet includes a wire disposed between an upper band-shaped material and a lower band-shaped material. A peelable cover is placed over the lancet tip to protect the tip of the wire and to ensure sterility. The manufacturing method comprises the steps of heating upper and lower band-shaped material, thermoforming the lower band-shaped material with a groove, inserting a recess in the lower band-shaped material, inserting the wire tes in the groove of the lower band-shaped material, so that its tip lies within the recess in the lower band-shaped material. Further, the bonding of the upper band-shaped material to the lower band-shaped material in a gluing station and the cutting of Abziehschlitzen in the upper and the lower band-shaped material to provide the cover is provided.
DE 101 42 232 A1 refers to an analytical tool with lancet and test element. The analytical aid comprises a lancet with a lancet needle and a lancet body. The lancet needle is displaceable relative to the lancet body, wherein the lancet body in the region of the tip of the lancet needle consists of an elastic material in which the tip of the lancet needle is embedded. An analytical test element is firmly connected to the lancet body. Furthermore, an analytical aid with a lancet is proposed, which likewise comprises a lancet needle and a lancet body, which is formed in the region of the tip of the lancet needle as a hollow body and which surrounds the tip of the lancet needle. The lancet needle is also according to this embodiment displaceable relative to the lancet body, wherein the hollow body consists at least partially of an elastic material.
Of the Invention is in view of the cited disadvantages of the prior It is an object of the present invention to provide methods with which and measuring devices appropriately connected and produced in a largely automated production process can be and to provide a combined lancing and measuring device which has been prepared by such a method.
According to the invention Task by the features of claim 1 and by the of claim 18 or 19 solved.
In A method step is a recess on the band-shaped carrier material produced, which preferably triangular is configured. As a result, a piercing tip is generated, with which the human skin can be punctured. The limiting the recess Edges are ground and sharpened, especially in the area of their tips that is on one long side of the band-shaped support material forms a suitable for piercing the human skin tip. The side of the band-shaped Support material, including a thin one Metal foil of 0.1 to 0.3 mm thickness can be used, is used to protect against injury, damage and to ensure surrounded the sterility of the final product with a plastic material. For this purpose, preferably a soft plastic strip enclosing the tips, such as silicone, used. The opposite of the piercing tips Side of the band-shaped support material is also provided with a strip to facilitate handling provided by plastic material, which opposite the piercing tips Side of the band-shaped support material surrounds on both sides. This made of any plastic material manufactured strips is used for better handling of the finished Lancing test strip composite. At this point in the production process can now the band-shaped support material with the embedded lancet tips that of soft plastic, like silicone, for example, are sterilized by β or γ irradiation.
On the band-shaped Support material in which the piercing tips are formed and which at the Punctured side of a strip with silicone material is enclosed, and the opposite Side is provided with a plastic material strip, is now applied the evidence. The area between the piercing tips covering soft plastic material and handling facilitating Plastic strip of the band-shaped support material is covered with a cover, which adjoins the detection element. The band-shaped carrier material is now completely covered. At the side where the ground and sharpened piercing tips are formed are, is the band-shaped support material surrounded by a silicone strip, to which a cover sheet followed. The cover lies on a strip on the band-shaped substrate applied detection element, which in turn to the handling of the band-shaped carrier material relieving plastic material. By the proposed method according to the invention let yourself achieve in an advantageous manner that the band-shaped carrier material, separated from which single SMD base body before applying a detection element by β or γ irradiation can be sterilized. Only after the sterilization of the band-shaped support material the detection element is applied, which by the sterilization of the band-shaped carrier material through β- or γ-irradiation is not impaired in its function and mode of action, because it does not this irradiation thanks to the subsequent application to the band-shaped substrate is exposed. The detection element can both in the area of the sharpened piercing tips be applied directly, as well as in the band-shaped substrate Covered wells that form a channel for capillary liquid transport cover. Both arrangement variants of the detection element are possible.

The wells 2 extend from the first end face 9 to the second end face 10 of the band-shaped carrier material 1 below the cover 21 and below the detection element 22 ,
From the illustration according to 6 is a single-SMD basic body with covered piercing tip and with a handle area.
According to the inventively proposed manufacturing method for combined measuring and piercing devices for detecting an analyte in liquid are from the band-shaped substrate 1 along the in 2 . 3 and 4 illustrated dividing lines 5 Single-SMD body 6 separated. These include both sides of the depression 2 acting as a capillary channel 23 serves, each a first lancet part 7 and a second lancet part 8th , The separation of the single SMD basic body 6 from in the feed direction 39 transported band-shaped substrate 1 forms on the first lancet part 7 a first separation point 24 and on the second lancet part 8th a second separation point 25 out. The well suitable for capillary liquid transport depression 2 lies below the cover foil 21 as well as below the detection element 22 , In the lower part of the single-SMD main body 6 this is with a section of the plastic cover 19 provided as a handle area 20 can act. The first front page 9 of the individual SMD basic body shown here 6 is from the silicone material cover 18 covered.

The depression 2 , the grooved or notch-shaped in the band-shaped substrate 1 can be formed, ends directly at the piercing tip 16 , The piercing tip 16 may have a ground front part similar to an injection needle. A capillary channel mouth 27 the depression 2 runs in the piercing tip 16 out. The depression 2 acting as a capillary channel 23 is used for capillary liquid transport is in a Kapillarkanallänge 38 educated. The width of the recess is denoted by reference numerals 37 and depends on the configuration of the punching or embossing tool, with which the wells 2 in the band-shaped carrier material 1 be generated. The single SMD basic body 6 includes a first lancet part 7 and a second lancet part 8th , at their dividing lines 5 from the band-shaped carrier material 1 each with reference numerals 24 or 25 designated separation pages arise. The depression 2 that the channel suitable for capillary liquid transport 23 forms, extends continuously from the Kapillarkanalmündung 27 at the first end 9 of the single SMD basic body 6 to the second end face 10 of the band-shaped carrier material 1 here covered by the plastic cover section 19 ,
With VIII-VIII or IX-IX are cross sections through the single-SMD base body 6 indicated, which closer from the 8th respectively. 9 emerge.
8th shows a cross section according to the in 7 registered sectional course VIII-VIII by a trained with rounded recess bottom suitable for liquid transcapillary capillary channel.
The band-shaped carrier material 1 is in the cross-sectional plane of the detection element 22 covered. The detection element 22 has a thickness 28 on; the thickness of the band-shaped carrier material 1 - Obtain preferably as a thin metal foil of 0.1 to 0.3 mm thickness - is denoted by reference numerals 30 indicated.
In the illustration according to 8th is the reason 4 the depression 2 as a rounding 34 educated. From that perpendicular to the plane according to 8th extending capillary channel suitable for capillary liquid transport 23 For example, a fluid supply is human blood, for example. This enters the detection element 22 and forms in this a soaked zone 33 out. The one in the depression 2 and the capillary channel 23 Recordable fluid supply 32 depends on the depth of the depression 2 , ie from the embossing depth in the band-shaped carrier material 1 from. At a capillary channel length 38 of about 15 mm and a capillary channel width 37 of about 0.25 mm, about 100 nl of human blood can be taken up in the capillary channel, provided that the reason 4 the depression 2 as a rounding 34 is designed. The time it takes to get a sufficient volume of fluid into the capillary channel 23 acting recess 2 below the cover 21 and the detection element 22 into the depression 2 Has occurred, depends on the nature of the capillary base forming surface of the belt-shaped carrier material 1 and the materials used for cover film 21 or for the detection element 22 from. If aluminum is chosen, its oxidized surface can be made very hydrophilic.
Out 9 the formation of a recess with a triangular cross section in the band-shaped carrier material emerges.
Also according to this embodiment, the band-shaped carrier material 1 at its top by a detection element 22 covered. In the one with a triangle shape 35 executed recess 2 a liquid supply occurs 32 - For example, human blood - and forms in the detection element 22 a saturated area 33 , Also as shown in 9 is the material thickness of the detection element 22 by reference numerals 28 identified while the material thickness of the band-shaped substrate 1 by reference numerals 30 is identified.
Depending on the geometry of the capillary channel 23 forming depression 2 - be their reason 4 as a rounding 34 or in triangular form 35 formed - can a corresponding liquid supply by capillary action under the cover 21 or the detection element 22 enter and the detection element section 22 on the single SMD base body 6 wet.
The in 6 respectively. 7 illustrated single-SMD basic body 6 can according to the method proposed by the invention individually from the strip-shaped carrier material 1 be separated; In addition, it is also possible by losweise perforation, for example, 5 or 10 packets of single-SMD bases 6 of band-shaped carrier material 1 separate. Be the single-SMD basic body 6 detached or packet by piece, so can along the virtual dividing line 5 individual perforations are generated, the easy separation of the respective outer single-SMD main body 6 from the respective batch.
The individual SMD base body obtained by the production method proposed according to the invention 6 represents a combined lancing and measuring device whose piercing tip 16 by embossing in the band-shaped carrier material 1 is formed and their measurement function in the same manufacturing process by applying the detection element 22 with one of the wells 2 covering cover sheet 21 is produced. The band-shaped carrier material 1 can also according to the inventive method with a detection element 22 containing cover 21 be coated that the detection element 22 in the vicinity of the piercing tip formed on an end face of the band-shaped carrier material 16 located. In such a variant of the method eliminates the capillary liquid transport to the detection element 22 forming, in the band-shaped substrate 1 embossed depressions 2 . 23 , Is the proof element 22 in the area of the sharpened or sharpened piercing tip 16 applied, becomes the detection element 22 immediately after piercing the single SMD base body 6 wetted in the human skin. When using the combined lancing measuring device according to the invention, the piercing tips 16 surrounding, preferably made of a silicone material soft plastic cover 18 residue-free on manual way from the piercing point 16 away. Due to the residue-free removal of the soft plastic material cover 18 from the piercing point 16 can either wetting one in the area of the piercing tip 16 applied detection element 22 take place, or on the other hand, a proper entry of a liquid in the capillary liquid transport enabling depression 2 . 23 which are in the single SMD basic body 6 can be guaranteed. Alternatively, instead of the soft plastic material cover 18 for covering the piercing tips 16 a hydrophilic plastic are selected, so that optionally in the region of the piercing tips 16 remaining residues do not hinder the wetting behavior of the sample.
The removal of the soft plastic material cover 18 , which may be made of silicone material or of a hydrophilic plastic, can also be automated by a measuring system, for example, when the measuring system comprises a device with a magazine for receiving the inventively proposed combined lancing and measuring devices for detection of an analyte in liquid. With regard to the wetting of the combined piercing and measuring device, it should be mentioned that the wetting of the combined piercing and measuring device takes place in a separate step, which is followed by the creation of a skin opening, by the piercing tip 16 is brought to a resulting on the skin surface drops of blood. The piercing tip 16 The combined piercing and measuring device can also be repeatedly brought to the resulting drop of blood, as well as repeatedly pierced in the skin opening to make contact between the exiting body fluid, such as blood and the capillary channel forming depression 2 . 23 or the detection element 22 or the combined lancing and measuring device to achieve.
A single processing by generating lancets and test strips in separate steps and a subsequent assembly of the individual elements can now be omitted, so that the proposed method according to the invention is particularly advantageous for mass production and the production of single-SMD base bodies 6 Making a combined lancing and measuring device, very cheap and affordable.
