    Next, at the time of urine collection, the examinee takes out the urine collection container 1 from the packaging bag and removes the cover tube 4 from the urine collection tube 3. Then, the urine collection tube 3 is attached to the storage tube 2, and the examinee grips the storage tube 2 with the urine collection tube 3 facing downward. Then, when the subject hangs urine on the urine collection port 33, the urine flows into the urine collection tube 3 from the urine collection port 33, accumulates in the measuring unit 31, and the collection of urine ends. At the time of urine collection, if a predetermined amount (for example, 10 ml) of urine is injected into the measuring unit 31, it leaks out of the urine collection tube 3 through the urine collection port 33, so that an amount necessary for urinalysis is reliably collected and surplus No urine is collected.

    When the collection of urine is completed, the urine collection container 1 is transported to an examination room or the like. There are two forms of conveying states at that time.

    In one form, as shown in FIG. 2, the urine collection tube 3 is inserted into the cover tube 4 with the urine collection tube 3 facing downward. As a result, the urine collection cylinder 3 which is a dirty part is covered. At that time, when the urine collection tube 3 is inserted into the cover tube 4, the urine collection port 33 is closed by the cover tube 4. Subsequently, when the urine collection tube 3 is rotated with respect to the cover tube 4, the cover tube 4 and the urine collection tube 3 are coupled and fixed by the fixing screws 37 and 43.

Further, when the cover tube 4 and the urine collection tube 3 are coupled, as shown in FIG. 2 , the opening end surface 4a of the cover tube 4 comes into contact with and closely contacts the stepped surface 3d of the large diameter portion 3b of the urine collection tube 3, and the cover The space between the tube 4 and the urine collection tube 3 is sealed. Further, when the urine collection tube 3 is inserted into the cover tube 4, the sliding surface 4 b of the cover tube 4 and the sliding surface 3 e of the urine collection tube 3 are brought into close contact with each other, and the space between the cover tube 4 and the urine collection tube 3 is sealed. . Therefore, leakage of urine collection is prevented.

    Subsequently, the urine-collecting container 1 is turned upside down, and the storage cylinder 2 is inserted downward into a container stand or the like and conveyed to an examination room or the like. At this time, when the urine collection cylinder 3 is turned upside down, the urine collection flows into the storage cylinder 2 and the urine is stored in the storage cylinder 2.

    Thereafter, when the cover 36 of the urine collection tube 3 is grasped in the examination room or the like and the urine collection tube 3 is rotated with respect to the storage tube 2, the fixing screws 23 and 35 are detached. In a state where the fixing screws 23 and 35 are removed, the storage cylinder 2 is detached from the urine collection cylinder 3 and the cover cylinder 4. Then, only the storage cylinder 2 in which the urine is stored is set in the inspection apparatus.

    On the other hand, another form of the transport state is a form in which a cap 25 is attached to the housing cylinder 2 for transport as shown in FIG. Even in this case, when urine collection is completed, the urine collection tube 3 is inserted into the cover tube 4 with the urine collection tube 3 facing downward. When the urine collection tube 3 is inserted into the cover tube 4, the urine collection port 33 is closed by the cover tube 4 as described above.

    Thereafter, when the urine collection container 1 is turned upside down, the urine collection of the measuring unit 31 flows into the storage cylinder 2, and the urine is stored in the storage cylinder 2. In this state, the fixing screws 35 and 23 of the urine collection tube 3 and the storage tube 2 are removed, and the urine collection tube 3 and the cover tube 4 are removed from the storage tube 2 at the same time. As a result, only the storage cylinder 2 in which the urine is stored is provided, and the cap 25 is fitted into the open end of the storage cylinder 2 and is transported to an examination room or the like in a container stand or the like. In this inspection room or the like, the cap 25 is removed from the storage cylinder 2, and the storage cylinder 2 is set in the inspection apparatus. When the cap 25 is fitted into the housing cylinder 2, the convex portion 2f of the cap 25 gets over and a fitting completion sound such as “click” is generated.

    In the urinalysis, the storage cylinder 2 is attached to a centrifuge, and after the liquid component and the solid component are separated, decantation is performed and the supernatant liquid component is discarded. Then, the storage cylinder 2 is inverted to remove the liquid component. However, since the rough surface portion 26 is formed on the storage cylinder 2, deposits remain attached to the rough surface portion 26. Become.

-Effect of the embodiment-
According to the embodiment, since the rough surface portion 26 to which the deposit adheres is formed on the inner surface of the storage cylinder 2, when the liquid component is removed in the urine test, the deposit reliably adheres to the rough surface portion 26. Will remain. As a result, a microscopic examination of the urine sediment can be performed with high accuracy.

Further, since the rough surface portion 26 is formed in the vicinity of the bottom portion of the storage cylinder, a predetermined amount of sediment required for the urine sediment can be reliably attached .

    Moreover, the above embodiment is an essentially preferable example, and is not intended to limit the scope of the present invention, its application, or its use.

    As described above, the present invention is useful for urine collection containers for urinalysis.
