Description

Details of the invention

[0001] The present invention relates to a test strip system comprising a container and a carrier suitable for this purpose, the test strip assembly being suitable for carrying out various types of chemical, biological or biochemical tests and evaluating them using a suitable analytical device.

[0002] Many such test strip systems are known in the prior art. However, most of these test strip systems have a uniform shape, i.e., a uniform number of containers arranged in series and usually connected to each other by small webs or bridges. Such assemblies are often used in analytical and diagnostic laboratories, particularly in PCR polymerase chain reaction systems, or as reaction containers for ELISA detection. The strip systems are colored, particularly white or black, or transparent in this case. This allows reactions stimulated by reagents, or also by light or other radiation, to be visualized in the test strip containers and analyzed, for example, with an appropriate filter. The containers housing such test strip systems usually have the same geometric design. They usually have a conical or semicircular shape in the bottom region, or are completely flat and cylindrical in the bottom region. The conical or semicircular shape has the advantage of reducing waste or loss of sample or reagent volume during mixing of reagents or at the start of an experiment. However, conical and semicircular shapes are not particularly suitable for detection because stray light, interference, or similar phenomena may occur in the area of ​​the bottom of the conical shape. Furthermore, the bottom of the container is usually coated with a special non-biological or biological coating, such as an antibody or antigen. This, in turn, can be more difficult or almost impossible in the case of a conical shape. Furthermore, evaluation of, for example, fluorescence phenomena or color changes when coating a conical shape is difficult or even impossible.

[0003] SUMMARY OF THE INVENTION Accordingly, the present invention aims to improve test strip assemblies having cavities, primarily those used for analyzing samples or reagents.

[0004] In particular, an arrangement is provided in which the reagents or samples used are processed with as little loss as possible.

[0005] Furthermore, it is intended to provide efficient and qualitative analytical conditions, particularly in terms of being able to evaluate and perform various analytical methods such as colorimetry, photometry, fluorescence, chemiluminescence, and electrochemiluminescence.

[0006] A further object is to provide a test strip assembly having a cavity that is easy to handle, particularly with regard to conducting experiments or tests with regard to safety, likelihood of confusion, and ease of handling.

[0007] A further object of the present invention is also to store all the reagents required for the test and make them available as a kind of "ready to use" test strip assembly that has high long-term stability with respect to storage.

[0008] This object is achieved by a test strip assembly having a cavity and a suitable carrier therefor according to independent claims 1 and 10. Advantageous refinements and preferred embodiments are specified in the dependent claims.

[0009] A test strip assembly with a cavity according to the present invention comprises a first region containing at least one container and a second region containing at least one container. The container in the first region has a transparent, flat bottom, while the container in the second region has a predominantly V-shaped or predominantly U-shaped bottom. The container in the first region is also referred to as a reaction or dilution container within the meaning of the present invention. Reagents can be introduced into the container in the second region, or they can already be present there and used to perform the test. For complex tests, a test strip assembly with a container according to the present invention can also have additional containers in the second region. Depending on the test being performed, different reagents from different containers in the second region can be mixed sequentially, if necessary, to perform the test. The container in the second region can optionally contain a buffer solution, and additional containers in the second region can contain special marking agents or other reagents. In the context of the present invention, a container can also be understood to mean a recess or cavity that can contain a fluid, primarily a liquid, and at least temporarily store it.

[0010] The bottom shape according to the invention of the container in the second region can accommodate the contents of the container almost completely, so that little residue remains and the test can therefore be carried out reliably.

[0011] The flat and transparent bottom shape of the container in the first region according to the invention allows for good and reproducible analysis of the reagent or sample using an appropriate analytical device, such as colorimetry, photometry, spectroscopy, light microscopy, ELISA, colorimetry, photometry, fluorescence, chemiluminescence, electroluminescence, etc.

[0012] According to an advantageous embodiment of the test strip assembly, the container with the reagent in the second area is covered and sealed with a film for safety against contamination or evaporation or for safety against spillage.

[0013] According to a further advantageous embodiment of the test strip assembly with a container, the film covering the second region is manufactured so that it can be pierced using a pipette tip. Furthermore, the film is made of a material suitable for sealing the test strip. In this case, the film can be firmly connected to the test strip by a suitable material or method. Suitable materials include adhesives, glues, and polymers that are compatible with the test strip material and have low vapor permeability, and are suitable for stable long-term storage, or methods such as welding using heat or light. The film can be single-layered or multi-layered and can include a carrier material, such as a polymer, light metal, or other material. Furthermore, the film material generally preferably has properties that ensure leak-tightness and durability, as well as the stability of the film and reagents.

[0014] According to an advantageous embodiment of the test strip assembly with a container according to the present invention, the containers in the first and second regions have rims. According to the present invention, the rim in the second region is taller than the rim in the first region. In this case, the rim in the second region is preferably 0.2 mm higher than the rim in the first region. The rim in the second region is preferably 0.4 mm higher than the rim in the first region. The rim in the second region is particularly preferably 0.6 mm higher than the rim in the first region. It has been found that an effective difference between the rim in the first region and the rim in the second region is a rim in the second region that is 0.5 mm higher. The slightly higher rim in the second region compared to the first region allows for significantly improved welding or adhesive bonding of the film to the test strip assembly. This allows for a longer shelf life and improved leak-tightness. Furthermore, the high vapor barrier between the entire test strip assembly and the film material also allows for long-term storage stability of the reagent.

[0015] According to a further advantageous embodiment of the test strip assembly with a container according to the present invention, the first region, except for the bottom portion, is made of an opaque, translucent, or transparent material. Materials primarily used for this purpose are thermoplastics such as polyethylene, polypropylene, polyamide, polymethyl methacrylate, or polystyrene. Thermosetting plastics such as melamine-formaldehyde resin (phenoplast) or UF aminoplast are also suitable for this purpose. However, it is also conceivable to use glass or glass silicates, as well as ceramics, for this purpose.

[0016] According to a further advantageous embodiment, cycloolefin polymers (COP) or cycloolefin copolymers (COC) are used, which materials are characterized by particular durability, high optical transparency in the visible spectral range, low intrinsic fluorescence, low water absorption and low vapor permeability.

[0017] It is also possible that the container in the first region is made of one material and the cavity in the second region has a different material, depending on which test conditions prevail at the time. Advantageously, the container in the second region can be made entirely or partially of an opaque, translucent or transparent material.

[0018] According to a further advantageous embodiment of the test strip assembly with a container according to the present invention, a barcode or marking for identifying the test strip assembly is provided. Such a barcode or marking can be, for example, a barcode, a QR code, an RFID code, or any other typical barcode or marking. The barcode can, in particular, contain information about the composition of reagents that may be present in the test strip assembly and thus provide information about the shelf life of the reagents if stored at a specific temperature and conditions. Furthermore, such a barcode can uniquely identify the test strip assembly associated with it, which is intended to prevent subsequent confusion or mixing of test results. Furthermore, such a barcode can be easily registered and read by a reader provided for this purpose, thereby ensuring the unique assignment of the test strip assembly to a specific patient or test, for example, and preventing unauthorized persons from assigning the barcode to a specific person based on a specific test or appearance. This ensures the anonymity of the test administration and its storage.

[0019] In a further advantageous embodiment of the test strip assembly with a cavity according to the invention, the lower end of the test strip assembly, more precisely the bottom of the first and second regions, has lateral guide webs. These guiding webs are used to precisely position the test strip in a carrier provided for this purpose and to allow for a configurable and releasable fixation. This allows, for example, pipetting, cleaning, and evaluation of the test, as well as ejection of the test strip from the carrier.

[0020] According to a further advantageous embodiment of the test strip assembly with a container according to the present invention, the container tapers from the first region to the second region in top view, or the second region has a section where the guide web does not extend. According to a further embodiment, the side of the second region is provided with a continuous material, resulting in a side that ensures a better tactile feel of the test strip assembly in the second region. Furthermore, the above-described embodiment of the test strip assembly and the carrier shape adapted to the shape of the test strip assembly means that the test strip assembly can only be positioned in a very specific direction or manner within the carrier. This prevents, for example, unintentional mixing of the first and second regions, and as a result, the test strip assembly cannot be inserted incorrectly, for example, into an analytical device, virtually eliminating misuse.

[0021] According to a further advantageous embodiment of the test strip assembly with container according to the invention, a clamp with a clamping spring on one side is provided. This clamp with a clamping spring has the advantage that the test strip assembly can be inserted into a carrier provided for this purpose and remains securely there. This connection can be released again with little force by pressing the spring with little force or by displacing the test strip within the carrier, so that the test strip assembly can be detached again from the carrier provided for this purpose.

[0022] According to a further advantageous embodiment of the test strip assembly with a container according to the present invention, the test strip assembly includes at least one reagent in at least one container in the second region and / or a coating in at least one cavity in the first region. In this case, the coating is advantageously limited to the bottom of the cavity. In the context of the present invention, coating is understood to also mean vapor deposition, printing, painting, spraying, and / or incubation. In the context of the present invention, coating here primarily refers to non-biological or biological coatings, such as antibodies, antigens, samples (e.g., blood or urine), specific chemicals, specific biological substances, DNA or RNA, etc. In an exemplary test scenario, a sample can then be applied to the container in the first region. One or more reagents from the container in the second region are then added, which induces a reaction that can then be analyzed in the cavity in the first region by an appropriate analytical instrument.

[0023] The present invention also includes a carrier for the test strip assembly. The carrier for a test strip assembly having a container according to the present invention is designed so that the test strip assembly can be releasably fixed in the carrier by a clamp and / or by a guide web that is pressed into a guide rail of the carrier provided for this purpose. According to the present invention, the test strip assembly can be introduced into the carrier by a clamp having a clamping spring and fixed to the carrier by a slight force of the spring. However, the present invention also makes it possible to remove the test strip assembly from the carrier again by applying a slight force to the spring. However, according to the present invention, the carrier can also be designed so that the test strip assembly can be pressed into the carrier, in which case the carrier has suitable guide rails or recesses for this purpose.

[0024] According to an advantageous embodiment of the carrier for test strip assemblies of the present invention, it has an additional spring, so that a test strip assembly inserted by a web into the carrier's guide rails provided for this purpose is also releasably secured on the carrier. Such a spring can be formed, for example, by a slightly bent metal piece. In this way, a slight force acts on one side of the test strip assembly. This force is sufficient to hold the test strip assembly accurately and stably in the carrier. However, the force is only large enough to still allow the user to displace the test strip assembly for installation or removal.

[0025] According to a further advantageous embodiment of the carrier for a test strip assembly according to the invention, the carrier has the shape of a rectangle, a full circle or semicircle, or a segment of a circle. In principle, the carrier can be designed with any geometric shape, provided that the carrier has a shape suitable for analysis by an analytical device.

[0026] According to a further advantageous embodiment of the carrier according to the invention for a test strip assembly, the carrier has a suitable complementary shape in order to function as a carrier unit in an analytical device suitable for this purpose.

[0027] A test strip assembly with a container according to the invention and a carrier according to the invention for such a test strip assembly are explained in more detail below in exemplary embodiments and in the drawings, which are merely exemplary and do not limit the general concept of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0029] FIG. 1 shows a conventional test strip assembly 10. It is clear that all containers 20 in the test strip assembly 10 have flat bottoms. Furthermore, the test strips can be used in holders provided for this purpose, but only loosely. A further drawback of the prior art test strip assembly 10 is that the test strips can be inserted upside down into the carrier. This can lead to sample mix-ups or confusion in the assignment of samples to specific patients or reference values. Another drawback is that the prior art test strip assembly 10 cannot be releasably secured within the carrier. For example, it is not possible to manually or automatically knock out air bubbles that could interfere with the detection reaction.

[0030] 2a is a schematic perspective view of one embodiment of a test strip assembly 10 according to the present invention. The illustrated test strip assembly 10 has a transparent, see-through material. The material can be selected depending on the application; for example, a black material can reduce scattered light or interference, while other materials can have other properties in turn.

[0031] Also shown is a clamp spring 150 for forming a clamp with a suitable carrier according to the present invention. Also shown in Figure 3a is a guide web 100 for guiding and securing a test strip assembly 10 according to the present invention in a suitable carrier. Also shown in Figure 2a is a first region 30 having a somewhat cylindrical container 20 and a second region 40 having a somewhat cubic container 20. Also shown is that the second region 40 has a taller rim 71 than the first region.

[0032] FIG. 2b shows the test strip assembly 10 according to the present invention, already known from FIG. 2a, with a film 80. The cover film 80 is applied to the slightly tall rim 71 of the container 20 in the second region. The film 80, also known as a sealing film, is designed to be easily pierced using a pipette tip. Furthermore, the film 80 has a coating designed to be resistant to burnout and to allow for structuring, inscribing, or printing. The film 80 also allows the test strip assembly 10 to be used as a kind of storage container with an integrated test device. For this purpose, one or more reagents are poured into one or more containers 20 in the second region 40 and sealed with the above-mentioned film 80. This can be done, for example, by welding or adhesive bonding. The protruding rim 71 of the cavity 20 in the second region 40 preferably has a height of 0.5 mm, which significantly improves the fixation of the cover film 80 to the test strip assembly 10. In this way, a more leak-tight seal is achieved for the reagents stored in the test strip assembly 10, resulting in a longer shelf life and greater stability. Additionally, the test strip and film materials have high vapor barrier properties, allowing for long-term storage stability of reagents. The cavity 20 in the first region 30, also referred to as the reaction or dilution cavity 20, can be coated with a product-specific antigen, antibody, or other protein or chemical in a further manufacturing process. For example, if such a reaction cavity or reaction vessel is coated with a product-specific antigen, it can detect specific antibodies present in, for example, a patient's serum. However, it is also possible to use other analytes, such as urine or CSF (cerebrospinal fluid), in addition to patient serum. Furthermore, in this example, the film 80 bears a barcode 90, which ensures unique and simultaneously anonymous assignment of the test and sample.

[0033] FIG. 3a shows an embodiment of the present invention. In this embodiment, a first region 30 with three receptacles 20 and a second region 40 with five receptacles 20 are clearly shown. The receptacles 20 in the first region 30 have a cylindrical configuration, while the receptacles 20 in the second region 40 have a more cubic configuration. A clamp spring 110 with lugs 150 is also visible, which is used to temporarily secure the test strip assembly 10 to the carrier. The sides in the second region 40 are designed to be flat, which allows for easier and more convenient handling for the user, for example, when inserting the assembly into the carrier. FIGS. 3b and 3c show front and rear views of an embodiment of a test strip assembly 10 according to the present invention. The lugs 150 used for securing within the carrier and the raised rim 71 for applying the film 80 in the second region 40 are clearly visible. FIG. 3d shows a bottom view of an embodiment of a test strip assembly 10 according to the present invention. Here, the guide webs 100 on the bottom surfaces of the first region 30 and the second region 40 are particularly visible.

[0034] 4a is a schematic side view of one embodiment of a test strip assembly 10 according to the present invention. The clamping by the clamp spring 100 is clearly visible, which further has small lugs 150 formed from the material of the test strip assembly 10. Lugs 150 are also visible on the opposite side of the clamp spring 100. These lugs 150, together with a similar opposing handle, allow the test strip assembly 10 according to the present invention to be firmly fixed in a carrier 120 suitable for this purpose. A slightly raised rim 71 of the cavity 20 in the second region 40, in contrast to the cavity 20 in the first region 30, is also visible.

[0035] FIG. 4b shows the embodiment of the test strip assembly 10 according to the present invention from FIG. 4a, viewed from above in a longitudinal section extending centrally through the test strip assembly 10 from front to rear. It can be seen that the cavities 20 in the first region 30 have flat bottoms 50, while the cavities 20 in the second region 40 have more of a V- or U-shaped bottom 60. This bottom shape of the cavities 20 in the second region 40 creates less dead volume when removing liquid. This means less test reagent or other liquid must be used, thus reducing general costs. It can also be seen that the clamp with the clamp spring 110 has a small lug 150 formed from the material of the test strip assembly 10.

[0036] 5a and 5b are schematic diagrams of a carrier 120 according to the present invention comprising an embodiment of a test strip assembly 10 according to the present invention, first with (FIG. 5b) and without (FIG. 5a) a film 80. An advantage of such a combination of carrier and test strip assembly is that individual test strip assemblies 10 can be easily removed from the carrier 120, while other test strip assemblies 10 can remain stationary in the carrier 120.

[0037] As can be seen in FIG. 3 , for example, the test strip assembly 10 is somewhat tapered in the first region 30 compared to the second region 40. This tapering allows the test strip assembly 10 to be correctly inserted into a carrier 120 provided for this purpose. This tapering therefore provides increased ease of use. Due to this shape, the test strip assembly 10 can only be inserted in one direction into the carrier 120 (also called a frame) provided for this purpose in accordance with the present invention. Therefore, incorrect handling is prevented from the start. The end user removes the test strip assembly 10, for example, with prefilled reagents and / or coated reaction or dilution containers 20, from the packaging provided for this purpose and inserts the test strip assembly 10, for example, from the front or top, into the carrier 120 provided for this purpose. Such a carrier 120 according to the present invention with the test strip assembly 10 according to the present invention is then placed in an analytical device, where the test is performed automatically or semi-automatically.

[0038] FIG. 6 is a schematic diagram of an embodiment of a carrier 120 according to the present invention, e.g., in the form of a circular segment without a test strip assembly 10 according to the present invention. The additional springs 130 of the carrier, which can removably fix the test strip assembly 10 by means of a counterforce, are clearly visible here. Guide rails 140 or recesses are also visible, into which the guide webs 100 of the test strip assembly 10 are introduced, thus further preventing the test strip assembly 10 from slipping out of the carrier 120 in an upward direction. It can also be seen that the carrier 120 has recesses in the form of through-holes 160, which are provided in the area behind which the first region 30 of the test strip assembly 10 is located. These through-holes 160 are provided to ensure the testing or analysis of the test reaction.

[0039] 7 is a schematic diagram of one embodiment of a carrier 120 according to the present invention having an inserted test strip assembly 10. Individual test strip assemblies 10, in this embodiment, can also be individually separated from the carrier 120 without other test strip assemblies 10 being adversely affected as a result.

[0040] The successive views of Figures 8a-8c show the insertion of a test strip assembly 10 according to the present invention into an embodiment of a carrier 120 according to the present invention. Here, the test strip assembly 10 is pushed laterally into the carrier 120 (Figure 8a). The test strip assembly 10 is firmly fixed in the carrier by the guide webs 100 and the guide rails 140 or recesses provided for this purpose. Due to the tapering of the test strip assembly 10 in the first region 30 and the complementary tapering of the carrier 120, the test strip assembly 10 can also be pushed completely into the carrier 120 in only one direction. An additional spring 130 installed in the carrier 120 prevents the test strip assembly 10 from slipping out. However, this clamping connection can be released again by the end user with a small force, so that the test strip assembly 10 can be removed from the carrier 120 again.

[0041] 9a and 9b are, respectively, further schematic diagrams of the possibility of mounting a test strip assembly 10 on the carrier 120 according to the present invention from FIG. 8. For this purpose, the test strip assembly 10 is introduced into the carrier 120 from above. Due to the aforementioned tapering of the second region 40 of the test strip assembly 10 and the complementary shape of the carrier 120, the test strip assembly 10 can be inserted into the carrier only in one direction from above. In the final step of this procedure, the test strip assembly 10 is again pushed forward with a small force, protected from slipping by an additional spring 130 installed in the carrier 120. Guide rails 140 or recesses on the carrier 120 and guide elements near the bottom, such as the web 100 of the test strip assembly 10, allow for precise guiding and positioning of the test strip assembly 10 during pipetting, washing, evaluation, and ejection of the test strip assembly 10 or the tests placed thereon. An additional spring or spring clamp element 110 allows for easy installation, removal, and feeding of the entire test strip assembly 10. Similarly, a spring 130 provided on the carrier 120 allows the test strip assembly 10 to snap into place on the carrier 120 in a manner that is audible and perceptible to the user to ensure that the test strip assembly 10 is properly inserted into the carrier 120.
