Abstract

A urine analysis system according to an embodiment includes: a testing apparatus that measures particles included in a urine sample according to a flow cytometry method; an image capturing apparatus that captures images of particles in the urine sample to acquire particle images; and a management apparatus that receives a measurement result obtained by the testing apparatus and the particle images acquired by the image capturing apparatus. The management apparatus generates an order to capture an image of the urine sample based on the measurement result obtained by the testing apparatus. The image capturing apparatus executes the image capturing processing of the particles in the urine sample for which the image capturing order has been generated by the management apparatus, and transmits the acquired particle images to the management apparatus.

First claim

The invention claimed is:

1. A urine analysis system comprising:
a first analyzer comprising a flow cytometer that analyzes urine particles in a urine sample by flow cytometry;
a second analyzer comprising a first controller programmed to perform operations to analyze a chemical substance in the urine sample with a test paper; and
an imaging apparatus comprising a second controller configured to capture an image of the urine sample and segment the captured image into a plurality of images of urine particles in the urine sample for categorization based on size,
a management computer communicably connected to the first analyzer, the second analyzer and the imaging apparatus, comprising a display and a third controller programmed to:
receive (i) a first test result, of the urine sample, generated by the first analyzer; (ii) a second test result, of the urine sample, generated by the second analyzer; and (iii) the plurality of images of urine particles in the urine sample, captured and segmented by the imaging apparatus;
categorize the plurality of segmented images of urine particles according to a plurality of categories based on size; and
cause the display to simultaneously display, according to the plurality of categories, the plurality of segmented and categorized images of urine particles and either or both of the first test result and the second test result corresponding to each of the plurality of categories of the plurality of images on a single screen.

2. The urine analysis system according to claim 1 , wherein the third controller is programmed to categorize the plurality of images of the urine particles according to a criterion and show the images in groups on the single screen.

3. The urine analysis system according to claim 2 , wherein the criterion includes a size of a urine particle.

4. The urine analysis system according to claim 2 , wherein the third controller also shows information on the single screen in response to detecting a urine particle which is categorized as an abnormal particle according to the criterion.

5. The urine analysis system according to claim 2 , wherein the management computer further comprises an input device, and wherein the third controller is programmed to show on the single screen, in response to a selection of any one of the groups:
a plurality of images of urine particles categorized in the group selected;
a region for inputting a type of urine particle appearing in each of the images; and
either or both of the first and second test results.

6. The urine analysis system according to claim 5 , wherein the third controller is programmed, in response to a selection of one of the images of the group selected, to show on the single screen, a selected image of a urine particle with its peripheral view.

7. The urine analysis system according to claim 6 , wherein the third controller is programmed to emphasize the selected image of the urine particle in the peripheral view.

8. The urine analysis system according to claim 5 , wherein the third controller is programmed to show the type of urine particle inputted in the region on the single screen.

9. The urine analysis system according to claim 1 , wherein the single screen comprises a comment box, and the third controller is programmed to show an abnormality message in the comment box in response to the first test result detecting a urine particle which is categorized as an abnormal particle.

10. The urine analysis system according to claim 9 , wherein the management computer further comprises an input device, and wherein the third controller is programmed to receive an input of a comment in the comment box.

11. The urine analysis system according to claim 1 , wherein the management computer further comprises an input device, and wherein the third controller is programmed to receive a designation of a part of an image of urine sample, and creates a new image by extracting the part of the image.

12. A management computer communicably connectable to:
a first analyzer comprising a flow cytometer to analyze urine particles in a urine sample by a flow cytometry;
a second analyzer first controller programmed to perform operations to analyze a chemical substance in the urine sample with a test paper; and
an imaging apparatus comprising a second controller configured to capture an image of the urine sample and segment the captured image into a plurality of images of urine particles in the urine sample for categorization based on size,

the management computer comprising:
a display; and
a third controller programmed to:
receive (i) a first test result, of the urine sample, generated by the first analyzer; (ii) a second test result, of the urine sample, generated by the second analyzer; and (iii) the plurality of images of urine particles in the urine sample, captured and segmented by the imaging apparatus;
categorize the plurality of segmented images of urine particles according to a plurality of categories based on size; and
cause the display to simultaneously display, according to the plurality of categories, the plurality of segmented and categorized images of urine particles and either or both of the first test result and the second test result corresponding to each of the plurality of categories of the plurality of images on a single screen.

13. The management computer according to claim 12 , wherein the third controller is programmed to categorize the plurality of images of the urine particles according to a criterion and show the images in groups.

14. The management computer according to claim 13 , wherein the criterion includes a size of a urine particle.

15. The management computer according to claim 13 , wherein the third controller also shows information on the single screen in response to detecting a urine particle which is categorized as an abnormal particle according to the criterion.

16. The management computer according to claim 13 , further comprising an input device, and wherein the third controller is programmed to show on the single screen, in response to a selection of any one of the groups:
a plurality of images of urine particles categorized in the group selected;
a region for inputting a type of urine particle appearing in each of the images; and
either or both of the first and second test results.

17. The management computer according to claim 12 , wherein the single screen has a comment box, and the third controller is programmed to show an abnormality message in the comment box in response to the first test result detecting a urine particle which is categorized as an abnormal particle.

18. The management computer according to claim 17 , further comprising an input device, and wherein the third controller is programmed to receive an input of a comment in the comment box.

19. The management computer according to claim 18 , wherein the third controller is programmed, in response to a selection of one of the images of the group selected, to show on the single screen, a selected image of a urine particle with its peripheral view.
