Description

  The present invention relates to an instrument and kit for anyone to use a test strip as a test means in a simple and safe manner, and can prevent diffusion of a specimen extract even if it is stored and carried. The present invention relates to a sample test container set and a sample test kit.

At present, the test strip is a testing means that can be used very easily in hospitals, clinics, clinics, laboratories, etc., and homes, and can quickly obtain analysis results.
Due to its simplicity and operability, test strips such as influenza test reagents have been developed and are widely available on the market. The method uses a cotton swab to collect specimens such as oral wipes and nasal wipes, soak them in the extract, disperse the specimens, and remove solid impurities by passing through a nozzle with a filter. Drop on top and measure.

  Conventionally, this test strip has a structure in which a membrane is attached to a support having a certain strength, and in some cases, a part of the test strip is covered with a tape. However, when measuring an infectious sample such as influenza, there is a risk that the measurer will be infected when using only the test strip.

As a method of solving this problem, a method of putting a test strip in a case formed of an impermeable solid material has already been disclosed (see Patent Document 1).
However, this method has a problem that it is necessary to produce a special case with a relatively complicated structure, which is very costly and complicated to operate in the case, and requires a lot of labor.

In addition, a method of sandwiching with a plastic film or a thin plate instead of the case is also disclosed, but in this method, the sample addition part is open and does not cover all the test strips, so there is a risk of infection. It is hard to say that it is fully removed. In addition, it is difficult to say that anyone can safely use the specimen extract because there is a risk that the specimen extract may be dropped outside the target location (see Patent Document 2).
