Indicator for diagnostic purposes.

The invention relates to an indicator for diagnostic purposes, with a to be wetted with the liquid to be examined Carrier substance in the form of a test strip * test sticker or similar.

Such indicators are widespread in diagnostics. The object of the invention is to design such an indicator in such a way that dsJ3 it is easy to handle, i.e. with the one to be examined Liquid is easy to bring into contact, and that a foreign infection by the sampler is excluded, i.e., that the sampler does not touch the test strip or test sticker with his hand.

According to the invention this object is achieved in that the carrier substance is completely enclosed by an envelope and / or can be tightly sealed with this.

In particular, the envelope contains a deep-drawn part in which at least one recess for forming a filling space Storage space for at least one carrier substance and to form connecting channels are formed.

This deep-drawn part is partially at least in the area of the storage rooms Completed by a cover film, in particular the cover film consists of aluminum and is on the deep-drawn part sealed from plastic.

Any remaining free space in the input area or output openings are sealed with adhesive tape * which can be removed for sampling or dispensing and after the corresponding process, the cover is removed again is lockable.

Further configurations of the indicator according to the invention are to be found in further subclaims.

An exemplary embodiment of the indicator is based on drawings explained in more detail, it show:

Figure 1: A perspective view of the indicator, and

Figure 2: a longitudinal section through the indicator along the plane A-A of Figure 1 in the practical Use.

The carrier substance that absorbs the liquid to be examined serves, consists in the illustrated embodiment from | two blotting paper 10 and 11, one of which with a specific detection reagent is soaked.

To accommodate these carrier substances 10, 11 is first a deep-drawn part 12, at one end of which is a funnel-shaped filling space 12A is formed, the lower end of which merges into connecting channels 12D, which lead to two storage spaces 12B, 12C for the carrier substances 10,11 lead. Further connecting channels then extend from these storage spaces 12B, 12C 12D to the bottom of the indicator.

In the area of the lower end of the filling space 12A until shortly before the lower end of the connecting channels 12D, the deep-drawn part is on 12 sealed a cover sheet made of aluminum, so that the

Storage rooms 12Bjl2G and the connections 12D (up to on their lower "end) are closed to the outside and the carrier substances 10, 11 in the storage rooms 12B.12C are held by their shape.

Over the entire kick side of the deep-drawn part 12 or the cover film 13 extends an adhesive tape 14, which thus also the upper part of the filling space 12A and the lower ends of the connecting channels 12D to the outside by being with the edge areas of the deep-drawn part 12 and the entire area of the cover film 13 is glued.

The practical use of this indicator is as follows (Figure 2);

The indicator is held down with the deep-drawn part 12, so that after the upper part of the adhesive tape 14 has been peeled off, a receiving space for the sample liquid 20 to be examined is formed. This sample liquid 20 then passes through the upper parts of the connecting passages 12B to the carriers 10,11, which are formed as blotting paper § platelets and of which beispiels-

'wise the blotting paper plate 11 with a specific detection liquid was soaked beforehand.

If the amount of sample liquid 20 offered is too large, it can be done by pulling on the lower part during the filling process of the adhesive tape 14, the opening of the lower part of the connecting channels 12D can be reached so that excess sample liquid can flow out there again. After taking the sample the adhesive tape 14 is stuck on again and the pack is thus tightly closed. If necessary, the adhesive tape 14 can also be used are labeled by the sampler with the specific data of the sample or the detection substance. Then it will turn again The sealed indicator is sent to the diagnostic laboratory, where the adhesive tape 14 and the cover film 13 are removed from the deep-drawn part 12 are removed and the carrier substances 10, 11 wetted by the sample liquid for carrying out the corresponding diagnostic methods can be removed.

An example of use for the indicator exists, for example In the veterinary sector, when examining the udder of dairy cows, the design of the indicator proves to be special advantageous because the milk from the udder can be injected directly into the infusion chamber 12A.

It goes without saying that the spatial arrangement of the storage rooms and the connecting channels on the respective

To facilitate handling, it can be provided, for example, that the adhesive tape 14 is the deep-drawn part in a corner region 14A 12 and protrudes beyond the cover film 13 so that it can then be pulled off more easily.
