Detailed Description
The invention will be further explained with reference to the drawings:
as shown in fig. 1-6, a micrometer auxiliary member for microscope eyepiece, includes eyepiece 1, 1 inner wall of eyepiece is female thread structure 7, micrometer 5 passes through in the auxiliary member eyepiece 1, micrometer 5 is circular shape transparent material, and laser etching scale or subregion line on micrometer 5, the auxiliary member structure includes extension pipe 2, and extension pipe 2 upper end is swivel 3, and extension pipe 2 lower extreme inboard is equipped with step 6 for place micrometer 5, be equipped with external screw thread 4 on the extension pipe 2 outside, external screw thread 4 corresponds with female thread structure 7 and is connected. And the micrometer 5 is etched with cross lines, and scales are arranged on X and Y axes of the cross lines. And a dust cover 8 is arranged on the rotating ring 3 of the auxiliary part. The rotating ring 3 is made by adopting a full-metal oxidation blackening process. The soft rubber ring is laid on the step, so that the peripheral ring of the micrometer can be better attached. The edge of the lower end of the extension pipe 2 is provided with a notch 9.
Example (b):
during the use, the auxiliary member lower extreme is towards the top, arranges the micrometer on extension pipe 2's step 6 with the micrometer, and soft rubber circle is laid to step 6, and the peripheral circle of better laminating micrometer through external screw thread 4 and internal thread structure 7 corresponding relation, connects the auxiliary member soon to the microscope eyepiece in, puts into the microscope with the eyepiece at last, can cover 8 lids on swivel 3 after the use, prevents that the fine dust from getting into the eyepiece, influences follow-up use.
For platelet value estimation: FIG. 4 shows that with the zone division function of this patent, the small circle area is one tenth of the full field of view, and the number of red blood cells N in the small circle of ten fields of view is counted under the eyepieceRBCAnd the total field of view is the number of platelets NPLTBy using
The red blood cell number of the full-automatic blood cell analyzer is calculated according to the formula: platelet count/L = [ N [ ]PLT÷(NRBCX 10) }) x number of erythrocytes/L, which, in the past, were not present due to the eyepiece itselfThe division of the area needs to count red blood cells in a full visual field, the workload is large, the counting is inaccurate due to too many red blood cells, the inspection efficiency is low, the introduction of the project can improve the inspection accuracy and the inspection efficiency, the method can be used for detecting the platelets by interference instruments for comparing the conditions of positive lipemia, cold agglutinin, red blood cell fragments, small red blood cells, large platelets, pseudoagglutination of platelets and the like, provides accurate and reliable inspection reports for patients, and has great value in the diagnosis and treatment monitoring processes of diseases and the like.
For morphology observation of red blood cells: FIG. 4 shows specific scale values, where normal red blood cells have a diameter of 6-9 μm, small red blood cells having a diameter of less than 6 μm, large red blood cells having a diameter of 10-15 μm, large red blood cells having a diameter of more than 15 μm, and large red blood cells having a diameter of more than 1 time, and different sizes of red blood cells; for platelet morphology observation: the normal platelets have a diameter of 1.5-3 μm, and are small when the diameter of the platelets is less than 1.5 μm, large when the diameter is 4-7 μm, and giant when the diameter is more than 7 μm, the size of the platelets varies when the diameters of the red blood cells differ by more than 1 time.
