Definitions
- the present invention relates to test kits with Test vessels, which have been shaped accordingly Plastic film and the welding of these molded Foil are formed on a base, and their use for performing analytical tests, in particular of immunological tests.
- the blister technology is primarily used for packaging used by tablets or pills of all kinds. But it is also used for packaging biological and technical products; e.g. Bulbs or screws blistered.
- elongated Bags made of two welded plastic foils educated; the bags are at the bottom at a point tapered and left open at the top. After filling e.g. the opening is welded to a serum sample. The tip is cut to remove the sample or slit on the side.
- the bags are supposed to used for storing, centrifuging or sending samples become.
- U.S. Patent No. US-A-3,660,033 (L.L. Schwartz) describes a flexible polyethylene bag for analysis e.g. one Urine sample.
- the bag sequentially includes a sample inlet, a reservoir chamber that can be closed compared to the former and a reaction chamber which holds a reagent for contains the sample and with the reservoir chamber through a narrow, lockable channel is connected.
- a part of Sample is fed from the reservoir into the reaction chamber, the rest can be kept or used for further testing become; for this, the connection openings are closed and the reservoir chamber along the cutting lines severed.
- Patent application WO-A-91/16086 (Target Research Inc.) describes a clear plastic bag for analysis of physiological fluids. On the top half the edge of the bag is open for sample loading; the lower half is made up of several compartments, which are open towards the top half, but closable, at the bottom to a cutable Tips are tapered and individually, along the weld lines can be separated. In the compartments, which are arranged on at least one of the bag halves, individual samples are taken and with chemical reagents brought into contact.
- test strip is used for many analytical tests, on porous material (e.g. cellulose, nitrocellulose) contains agents necessary for the test. In the course some test procedures the test strip has to be used once or washed several times with washing solution.
- porous material e.g. cellulose, nitrocellulose
- test kit eg for an ELISA test (E nzyme- L inked I mmuno S orbent A ssay) is described.
- blister technology does not use this test kit.
- It consists of a test strip in the form of a column made up of several layers, for example made of filter paper or plastic, which sits in a glass tube that is open at both ends.
- One or more layers of the column carry a reagent bound to them, in particular a known antigen or the corresponding antibody; they are kept apart by inert separating layers.
- the solution to be tested, as well as any washing solutions are drawn into the tube by applying a vacuum to the upper end of the tube.
- the solutions are removed from the tube by applying positive pressure.
- Patent application WO-A-93/07474 (Hawaii Chemtect International) describes an analysis kit for testing Food, in particular for the detection of fish toxins. It includes a stiff, yet flexible, non-porous, preferably waterproof pad on one to blister deformed clear plastic film is attached.
- the Blisters contain liquid reagents. Wear halfway up Foil and underlay a crease line, which at the same time runs through the top of the blister. Will the cutlery Bent back along this line, it takes the form of a Gable roofs and can therefore stand upright be used; at the same time, the blisters disclosed at their upper ends and the reagents contained accessible for the intended reaction.

- the material from which the pad is made is impermeable to water.
- the impermeability to water results from the fact that in most cases the Solutions contained in blisters are aqueous solutions or the reactions taking place in water or in an aqueous Medium take place.
- Examples of the material of the underlay are aluminum foil, plastics such as PVC, and plasticized paper or cardboard. These materials are opaque, which is probably the more common case; however, the opacity to light is not imperative Texture characteristic of the underlay.
- the base can in particular have a square shape exhibit.
- the base and the film can optionally be made of consist of the same material, at least their materials should be selected such that they can be welded together and / or can be glued and when welding or glue a tight connection.

Description
Der Siphonblister kann allerdings auch vorerst zur Durchführung einer Reaktion verwendet werden, indem eine Reagenzlösung eingefüllt und darin ein Teststreifen eingetaucht wird.
Der Teststreifen 2 besteht beispielsweise aus einem Kunststoffstreifen 21, der so lange ist, dass er sich über das Ende des Behälterteils 11 hinaus in den Entnahmeteil 12 erstreckt, und auf dessen einer Seite zumindest teilweise ein saugfähiges Material 22, z.B. Celluloe, Nitrocellulose oder sehr feine Glaswatte, aufgetragen ist. Darauf sind die für den jeweiligen Test benötigten Antikörper, Antigene oder andersartigen Reaktionspartner angeordnet, wobei eine oder mehrere Testflächen ausgebildet sein können.
Um beim eigentliche Test als Siphon funktionieren zu können, werden beide Enden des Siphonblisters durchgeschnitten. Zur Durchführung einer Reaktion im Siphonblister kann auch zuerst nur sein nach oben weisender Ast geöffnet werden. Um das Durchschneiden des Siphonblisters zu erleichtern kann das Testbesteck entlang Linien 3, 3', die am oberen bzw. unteren Ende des Testbestecks liegen, vorperforiert sein.
