Test Principle

 

Machine vision has been applied to morphological analysis, and realizes the identification, classification, counting of the urine particles automatically.

 

 

Core Technology:

 

(1)   Machine Vision technology:

 

   Automatically analyze and identify negative and positive samples, rapidly screen the negative samples.     Automatically identify, classify and count various urine formed elements by LP(10X) lens and then by HP(40X) lens.

 

  Automatic morphologic analysis insures objective and reliable test results. The positive samples only need verification on screen without any further manual microscopic examination.

   Conduct all parts of the equipment working harmoniously. No manual operation required in the whole process.

 

(2)   Automatic target locating and tracking technology

 

     LP(10X) Full-field scanning to locate all the targets, HP(40X) automatically tracking and enlarging the small targets to identify and classify their fine structures.

 

     Directly detect the native urine samples and effectively avoid the error caused by centrifugation.

 

 

Sampling System:

 

Precise pump and valve system filling-up counting chamber with sample urine automatically. Bi-directional cleaning the counting chamber, pipeline system and inner and outer sides of the probe. Effectively avoid cross contamination.

 

 

Full automatic Digital Biological Microscope

 

(1)   LP(10X) and HP(40X) switches automatically.

 

(2)   Auto-focusing microscope.

 

(3)   Auto-moving from left to right and scan the counting chamber line by line to realize the full-field scanning.

 

(4)   Condenser automatically adjusts the lights intensity.

 

 

Intelligent Self-Learning Function

 

The misidentified target will be memorized and used to update the database, and the automatic identification capacity will be improved step by step.

 

 

Quality Control

 

The self-test software running with the SFDA approved quality controls meets the quality control demand.
