Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to Spitz used for collecting a sample in a urinary sediment examination method.

[0002]

2. Description of the Related Art Conventionally, there is a urinary sediment examination method as a clinical examination method for analyzing formed components in urine. This urine sediment test method
About 10 cc of urine is collected in a spitz, and the urine collected in this spitz is centrifuged to separate a precipitate and a supernatant. Then, the supernatant liquid is removed by suction with an aspirator, only the precipitate is left, the precipitate is stirred, and then a predetermined inspection is performed.

[0003]

However, in the conventional spitz, it was necessary to use an aspirator in order to leave the precipitate in the spitz. Therefore, the work of removing the supernatant liquid is complicated, a space for accommodating the aspirator is required, the cost for preparing the aspirator is required, and the working time is long.

The present invention solves the above problems and makes it easy to leave urine precipitates in the spitz, especially to remove the supernatant liquid, and to use a device other than Spitz (such as an aspirator) by a decantation system. It is an object of the present invention to provide a spitz for urinary sediment examination that does not require the.

[0005]

The present invention has been made in order to achieve the above object, and the spitz for examining urinary sediment of the present invention has a large volume which mainly contains a supernatant liquid when urine is centrifuged. Part and a small volume part that mainly stores the precipitate when urine is centrifuged, and a liquid locking part that protrudes inward of the small volume part is formed at the point where the small volume part contacts the large volume part. The small-capacity portion has a narrow communication port to the large-capacity portion.

The large-capacity portion is a portion that mainly stores the supernatant liquid when the stored urine is centrifuged (the precipitate is also stored if there is a large amount of sediment), and is usually formed to a volume of about 12 cc. ing. This large-capacity portion has, for example, a cylindrical shape,
It is formed in a truncated cone shape or a combination thereof.
Then, in the vicinity of the small volume portion, it is preferable that the inner diameter becomes smaller as it gets closer to the small volume portion, and it is more preferable to form a substantially linear taper portion having an acute angle with respect to the axis. With this configuration, when urine is poured into the spitz, it can smoothly flow from the large capacity portion to the small capacity portion. The angle of this taper with respect to the axis is about 10
It is preferably within the degree. Further, water repellent treatment may be performed in the vicinity of the small volume portion, which facilitates the inflow of urine into the small volume portion.

The small volume portion is a portion mainly containing a precipitate when the stored urine is centrifuged, and is usually formed to have a volume of about 0.2 cc. The small-capacity portion is formed, for example, in a cylindrical shape or a truncated cone shape, and when formed into a cylindrical shape, the inner diameter thereof is preferably 4 to 6 mm, more preferably 4.5 to 5 mm.

The liquid locking portion projects inwardly of the small-capacity portion at a position where it contacts the large-capacity portion of the small-capacity portion and narrows the communication port to the large-capacity portion of the small-capacity portion, thereby making the spitz oblique. At this time, the sediment contained in the small volume section is prevented from flowing out from the small volume section. The diameter of this communication port is
It is preferably 3 to 5 mm, more preferably 3.5 to 4 mm.

The urine sediment inspection spitz as described above can be formed of glass, polypropylene resin, polyethylene resin or the like.

The Spitz for urinary sediment examination of the present invention is
Usually, the decantation method is used, but an aspirator can also be used.

[0011]

In the urine sediment inspection spitz of the present invention, when the supernatant liquid is removed after centrifugation, the whole liquid is discharged by inclining the whole at a slant, but the small volume portion is filled with the supernatant liquid. The deposited precipitate is retained by the liquid locking portion and is accommodated in the small capacity portion.

In addition, in the urine sediment examination spitz of the present invention, when filling urine, the urine put into the urine sediment examination spitz is transmitted from the upper portion to the lower portion of the large volume portion, and smoothly flows into the small volume along the taper portion. Flows into the department.
