Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple test paper packaging in which a simple test paper using urine, feces, blood or the like as a test material for the test is safe without directly touching the hand, and the judgment result can be easily determined. It is about materials.

[0002]

2. Description of the Related Art Conventionally, in a biochemical test using urine, feces, blood or the like as a material, and an immunological test, a simple test method using a test paper involves immersing one end of the test paper in the test material as it is, A method of directly dropping a test material on paper is widely used in practice. Such a method has the advantages that it is simple and inexpensive to manufacture, and that the inspection result can be generally determined visually, so that no special mechanical equipment is required.

However, since the simple test strip has no cover, the test material attached to the test strip may come into contact with an inspector or a third party, and there is a risk of contact with harmful bacteria or pathogenic viruses of the subject. There was a disadvantage.

Some simple test papers are used in a state of being stored in a plastic container. However, in order to make a plastic container, it is necessary to make an expensive mold, and a small amount of production is required. There is a problem in that a product that is only available becomes extremely expensive. Further, when a plastic container is used, it is necessary to provide a window in the judgment part to expose the test paper because of lack of transparency. (Patent publication Hei 7-46107)

[0005]

SUMMARY OF THE INVENTION The present invention provides an inexpensive simple test paper which covers a simple test paper with a transparent plastic wrapping material and improves the safety by making a judgment as it is, without affecting the test results. The main task is to provide a packaging material for paper.

[0006]

As a remedy, a packaging form called a blister pack is used in which a transparent plastic film is processed according to the shape of a product by a vacuum forming method or a pressure forming method. In this packaging form, since it is easy to mold according to the shape of the simple test paper, it is possible to seal the portion other than the sample input portion, and to hold the test paper, dry holes and the like relatively freely as required.

FIG. 1 is a plan view showing a form of packaging according to this method, and shows one form. However, a plurality of forms having this shape may be continuously connected. Generally, it is sufficient to have a sample port (1) for inserting a sample, and if necessary, a holder (2) for holding a simple test paper or a drying hole (4) for accelerating drying may be provided. good. The central part is the determination part (3). It is desirable that the judging unit be close to the test paper in order to facilitate the judgment. In addition, the test paper is used by sticking it on the mount (5).

[0008] The material of the packaging material is not particularly limited as long as it is a transparent plastic suitable for vacuum forming or pressure forming. For example, hard vinyl chloride or styrene resin is preferably used. The thickness of the film is not limited as long as it can be processed. Further, the mount may be paper or a plastic sheet or a metal plate.

FIG. 2 is a plan view of the simple test paper. The simple test paper shown here is a configuration diagram of a simple test paper called an immunochromatography method, which is generally widely used in a human hepatitis B diagnostic kit, a fecal occult blood diagnostic kit, and the like. This test paper has a reaction reagent-containing part (7) next to the sample dropping part / sample dipping part (6), and is followed by a judgment part (8). The judgment part has a positive part (11), a reference part (12), or only a positive part, and the test result is clearly distinguished from a negative part having no change by a change in color or appearance of a line. The reference section is provided for comparison and termination of the reaction, and need not always be provided. Further, a water-absorbing filter paper (9) is arranged following the judging section. This aims to make the test liquid flow quickly in one direction. These are all used by attaching them to a mount and fixing them. The simple test strip is not limited to the immunochromatography method, and can be applied to a biochemical test such as a urine test strip.

FIG. 3 shows a state in which a simple test paper is stored in the packaging material of the present invention. The sample dropping part / sample dipping part (6) of the test paper is located at the center of the sample port (1) of the packaging material, and the judgment parts are set so as to overlap each other, and the mount and the packaging material are bonded. The bonding method is not limited to gluing or welding.

[0011]

Next, the operation of the present invention will be described. A simple test paper is stored in the packaging material of the present invention as shown in FIG. 3, and a test sample, for example, serum is dropped into the sample port. The serum is absorbed by the sample dropping part and moves to the determination part by capillary action. The serum moves further and is absorbed by the absorbent paper. When a test substance is present in the test serum, a line or color change appears in the judgment section, so that the judgment can be made visually from above the judgment section of the packaging material. Further, the establishment or termination of the reaction is determined based on the appearance of a line or color change in the reference portion.

[0012]

Example 1 A simple test strip for hepatitis B antigen test is attached to a mount. Since the subject of the present invention resides in the packaging material, the description of the simple test paper is omitted. The transparent vinyl chloride blister pack of the present invention is placed so that the sample port of the blister pack is located at the sample dropping portion of the test paper, covered with the blister pack, and glued to the mount. The reference HBs antigen solution and the test serum were dropped into the sample port, and the results were judged 30 minutes later. As a result, no difference was observed in the measurement sensitivity as shown in the table below. At that time, a simple test paper for hepatitis B antigen test was compared as it was, and a simple test paper stored in a molded plastic container was compared.

[0013]

As described above, since the blister pack packaging material for simple test paper of the present invention seals the area other than the sample port, the test paper after the inspection is in direct contact with the inspector or a third party. Safe without any. In addition, since it is transparent, there is no difference from the case of direct determination. Furthermore, there is an advantage that the shape of the packaging material can be easily changed at low cost according to the shape of the test paper.
