Benefits of technology

[0010] The primary object of the present invention is to provide a blood testing unit, which enables a blood test to be performed with a simple operation, such that a person in charge of the blood test may not come in touch with blood plasma or blood serum at the time of the blood test.

Problems solved by technology

Therefore, there is the risk that persons in charge of the blood tests will come in touch with the blood plasma or the blood serum by mistake and will catch an infectious disease, such as HIV.
Therefore, considerable time and labor are required to perform the blood test.

first embodiment

[0178]FIG. 1 is an exploded perspective view showing a blood testing unit 10, which is the blood testing unit in accordance with the present invention. FIG. 2 is a partially cutaway side view showing the blood testing unit 10 of FIG. 1. As illustrated in FIG. 1 and FIG. 2, the blood testing unit 10 comprises a circular cylinder-shaped outer vessel body 11, whose lower end area in FIG. 1 and FIG. 2 is open, and a circular cylinder-shaped inner vessel body 21, which has a bottom wall 23 at a lower end area in FIG. 1 and FIG. 2. By way of example, each of the outer vessel body 11 and the inner vessel body 21 is made from a transparent synthetic resin. The outer vessel body 11 has a size of, for example, an outer diameter of 15 mm×a height of 30 mm. The inner vessel body 21 has a size of, for example, an outer diameter of 10 mm×a height of 30 mm. Alternatively, each of the outer vessel body 11 and the inner vessel body 21 may be made from glass, or the like.

second embodiment

[0234] A blood testing unit 10A, which is the blood testing unit in accordance with the present invention, will be described hereinbelow with reference to FIG. 7. In FIG. 7 (and those that follow), similar elements are numbered with the same reference numerals with respect to FIG. 1 to FIG. 6.

[0235] The blood testing unit 10A illustrated in FIG. 7 is constituted basically in the same manner as that in the blood testing unit 10 shown in FIG. 1 to FIG. 6, except that the reagent layer 24 is not formed on the side of an inner vessel body 21A and is formed on the side of an outer vessel body 11A. The reagent layer 24 is formed such that the reagent layer 24 is in contact with the back surface of the blood constituent separating membrane 16 located within the outer vessel body 11A, which back surface is opposite to the surface that stands facing the rubber film 15.

[0236] In cases where the blood testing unit 10A constituted in the manner described above is utilized, the blood test is ca...

third embodiment

[0239] A blood testing apparatus 40B, which is the blood testing apparatus in accordance with the present invention, will be described hereinbelow with reference to FIG. 9. The blood testing apparatus 40B illustrated in FIG. 9 is constituted basically in the same manner as that in the blood testing apparatus 40A shown in FIG. 8, except for a constitution of a light intensity measuring section 55. Specifically, the light intensity measuring section 55 comprises the two-dimensional photodetector 50 and an image forming lens 56. Also, in the blood testing apparatus 40B, the light radiating end face of the light guide member 45A comes into contact with the bottom wall 23B of the inner vessel body 21B. Therefore, the distance between the image forming lens 56 of the light intensity measuring section 55 and the reagent layer 24 and the distance between the two-dimensional photodetector 50 of the light intensity measuring section 55 and the reagent layer 24 are kept at predetermined values...

Abstract

A blood testing unit comprises a closed vessel having a blood introducing section formed at a certain area of the closed vessel. A blood constituent separating section is located within the closed vessel to separate plasma and / or serum from the blood sample introduced through the blood introducing section into the closed vessel. A reagent layer is located within the closed vessel, such that the reagent layer can be seen from the exterior. The reagent layer comprises a region for spreading the plasma and / or the serum, which has been separated by the blood constituent separating section from the blood sample, and a reagent supported on or in the spreading region, the reagent undergoing a reaction with the plasma and / or the serum and forming a color as a result of the reaction.

Description

[0001] This application is a divisional of co-pending application Ser. No. 10 / 400,585, filed on Mar. 28, 2003, the entire contents of which are hereby incorporated by reference and for which priority is claimed under 35 U.S.C. § 120.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to a blood testing unit for use in performing a test of blood of humans and other animals. This invention also relates to a blood testing method and apparatus using the blood testing unit. [0004] 2. Description of the Related Art [0005] As blood testing units for use in performing tests of blood of humans and other animals, blood testing units comprising a slide-shaped support and a reagent layer carried on the slide-shaped support, which reagent layer is capable of undergoing a reaction with blood plasma or blood serum and forming a predetermined color, have heretofore been proposed. The blood testing units are proposed in, for example, U.S. Pat. No. 5,051,901. [0...
