Abstract

(57) [Abstract] [Purpose] As a blood image inspection apparatus for a blood test of a human body or an animal, the present invention provides an inexpensive and accurate blood test apparatus capable of comparing and distinguishing the internal structure of a blood cell such as a blood cell fraction with a standard image. The purpose is to provide. A blood image inspection apparatus of the present invention comprises an image memory for storing a blood image from a sample and a standard image memory for storing a standard image of blood cells, and the images from both memories can be compared. The comparison work can be automated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood image inspection apparatus, and in particular, in observing a blood image for an operator to make a judgment, a standard image can be displayed together with a detected blood image for comparison. Blood image inspection apparatus.

[0002]

2. Description of the Related Art In general, as blood test devices, various devices for performing blood cell counters, blood image classification tests, and biochemical tests have been proposed. The above two are used for general tests, and the third biochemical test is used. For the test, blood is dropped as a sample on a test paper in which a reagent is immersed, and the color resulting from the chemical change is optically identified to perform the test.

Therefore, the electronic device industry association ""
86ME Equipment Technical Guide "P. 209 to 210, the equipment related to the above-mentioned inspection is introduced.

[0004]

Since the blood cell counter in the conventional example described above detects only the numbers of blood cells and platelets, it is not possible to detect even the internal structure of blood cells such as the fraction of white blood cells. Further, in the above-described blood image automatic classification device, since the device itself uses a sophisticated computer, not only becomes very expensive, but also becomes large in size.

[0005]

According to the present invention, a sample is irradiated with light from a light source, a blood image is read by a detection unit, and the standard image is displayed on the display unit. This is a configuration that facilitates the comparison of.

[0006]

In the present invention, the blood image of the sample by the detection unit and the standard image previously stored in the memory can be simultaneously displayed on the display unit, and the judgment of the blood image of the sample can be made by the comparison. The judgment result becomes quick.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a blood image inspection apparatus of the present invention, and FIG. 2 is a screen state diagram of the apparatus.

(16) is a third switching section, (17) is a video composition section,
(18) shows a display unit, and (19) and (20) show a keyboard and a mouse as input means. (21) shows a main screen section, and (22) shows an image output control section.

The operation will be described below. First, the sample (1) is a sample to which blood is applied dropwise and is mounted on the sample table (2). As a basic element of the sensor system, a line type CCD sensor and a rotary plate or a surface type CCD sensor are provided in the detection section (5), and light from a light source (3) is irradiated to the sample (1) to obtain a microscope image. The detection section (5) converts the electric signal.

The optical image control section (6) receives the electric signal and generates an electric signal and a mechanical output for adjusting the brightness and the focus of the image, and the electric signal and the mechanical output are used to obtain a desired optimum detection. Set to state.

Further, the output of the detection section (5) is applied to the A / D conversion section (9) and converted from an analog signal to a digital signal. The image input control unit (8) includes a detection unit (5), an A / D conversion unit (9) and a second switching unit (13).
A signal is sent to the image memory (11) through the optical memory, and the optical image obtained by the detection unit (5) is stored in the image memory (11).

The contents of the image memory (11) are output by the image output control section (22) through the second switching section (13), and the second D / A conversion section (15) outputs D / A (digital / digital). After analog conversion), it is displayed on the display unit (18) through the video synthesizing unit (17).

Here, the standard image memory (14) receives simple signals such as a video clock and horizontal and vertical synchronizing signals from the image output control unit (22), and the standard blood cells are displayed on the peripheral portion of the display unit (18). Generate a signal to display the dynamic image.
Next, the CPU (7) adjusts the operation of each of the above-mentioned parts by each switching part, specifies the light source color of the light source (3), automatically counts blood cells by digital image processing, or counts blood cells counted by an operator (operator). Is displayed and various coefficients are calculated based on them.

The image signals output from the image memory (11), the standard image memory (14) and the CPU (7) are combined in a video combining unit (17) to display the display unit (1).
8) The screen is displayed on the screen.

As input data means, a keyboard (1
9) or a mouse (20) is connected and is used for setting the operation mode of the present system and blood image fractionation operation by the operator.

Next, referring to FIG. 2, the display unit (1
As a display screen of 8), a microscope image of the sample (1) is displayed in the main part of the screen, and a standard image of white blood cells to be fractionated is displayed in the right end part. In the screen example of FIG. 2 described above, the data corresponding to the image displayed on the main screen section (21) is counted according to an example in which 1 to 5 blood cells are present within a certain area as the standard image, and the standard image is displayed. Image (No. 1 ~
