Problems solved by technology

On the other hand, when using a porous material structure such as a polysulfone membrane and a blood component separation membrane formed of glass fibers, there may be a problem that Na, Ca, Cl, etc. of the glass fibers dissolve out and affect the test value.
In addition, when a blood component separation membrane formed by a knife that cuts blood cells is set in a part of a porous material structure such as a polysulfone membrane, the structure of the blood component separation membrane is complicated due to the knife, and it is difficult to determine the application of blood test components. restricted

Embodiment

[0135] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0136] figure 1 is a disassembled perspective view of the blood test unit 10 according to an embodiment of the present invention, figure 2 is a partial cross-sectional side view of the blood test unit 10 . As shown in the figure, this blood test unit 10 includes a cylindrical outer cylinder 11 with an open lower end in the figure, and an inner cylinder 21 with a bottom surface at the lower end in the figure. The outer cylinder 11 and the inner cylinder 21 are made of transparent synthetic resin, the outer cylinder has an outer diameter of about 15 mm x a height of 30 mm, and the inner cylinder has an outer diameter of about 10 mm x a height of 30 mm. In addition, the outer cylinder 11 and the inner cylinder 21 are made of glass in another example.

[0137] The upper end surface of the outer cylinder 11 in the drawing is a bottom surface 14 having a...

Abstract

A blood constituent separating membrane constituted substantially of polysulfone membrane separates blood plasma and / or blood serum from a blood sample. Reagents which are supported on the reagent layer have a portion for spreading the blood plasma and / or the blood serum separated from the blood sample, and when the reagent layer comes into contact with the blood constituent separating membrane, the blood plasma and / or the blood serum spreads over the reagent layer. The reagent forms a color as a result of a reaction with the blood plasma and / or the blood serum.

Description

technical field [0001] The present invention relates to blood test components used for blood tests of humans or other animals. Background technique [0002] In the past, as a blood test component used in blood tests of humans or other animals, as disclosed in Japanese Patent Publication No. 8-10193, a reagent that reacts with plasma and / or serum and develops color is carried on a slide-like support. body. [0003] When such a blood test device is used, after dropping plasma or serum on the reagent layer formed there, light is irradiated to the color-forming reagent layer, and the amount of reflected light is measured. Based on this amount of reflected light, it is possible to quantitatively analyze the amount of light in the plasma or serum. concentration of a particular substance. The aforementioned Japanese Patent Publication No. 8-10193 discloses an analyzer for performing blood tests in this way. [0004] The above-mentioned plasma or serum for examination is separate...
