Description
Technical field
It the utility model is related to a kind of sperm morphology measurement apparatus.
Background technology
Sperm includes head, neck, stage casing, principal piece and endpiece., can be in oily Microscopic observation after improveing pap staining
Sperm morphology, neck of sperm, stage casing, principal piece and endpiece deformity are easier to distinguish.But there are many types, size in the head of sperm
Differ, it is difficult in normal one boundary of the man-made division between abnormal spermium form, so sperm morphological analysis has master
The property seen, and be particularly difficult to standardize（WHO point out eupyrene sperm head must be in shape smooth, radian rule, substantially
Upper is ellipse）.
Eyepiece chi mark is installed on the diaphragm of eyepiece lens barrel, for measuring the object length in the visual field, domestic most reproductions
All it is the normal morphology rate for using the method for seeing piece under light microscope mirror to assess sperm before centrales, people is tested at only a few center
Member uses eyepiece chi mapping amount sperm head.Because existing eyepiece chi mark is generally divided into two kinds, one kind is by longitudinal scale and horizontal stroke
The cross scale formed to scale（As shown in Figure 5）, another kind is latticed（As shown in Figure 6）, in measurement sperm head
It is very inconvenient during length and width, while need to manually compute length-width ratio.Existing eyepiece chi mark, which can not measure sperm head, is
It is no smooth, if to meet radian rule, whether be generally ellipse.
Due to the poor operability that the difference in shortage objectivity, understanding and external mass control are assessed, manual evaluation
Sperm morphology has many difficulties.
The content of the invention
The technical problems to be solved in the utility model is：A kind of sperm morphology for being capable of rapid evaluation sperm morphology is provided to survey
Device is measured, whether the length and width scope that the device can easily measure sperm head meets normal range value, while can
It is whether smooth quickly to measure sperm head, if to meet radian rule, solve the above-mentioned problems of the prior art.
Solve above-mentioned technical problem technical scheme be：A kind of sperm morphology measurement apparatus, including microscope, described is aobvious
Micro mirror includes eyepiece, and sperm morphology measuring scale mark is additionally provided with eyepiece lens barrel diaphragm, and described sperm morphology measuring scale mark is
It is made up of the different sperm head compares figure of setting circle and 3~10 sizes, the center of circle of described setting circle and the center of eyepiece
Overlap, each sperm head compares figure is made up of big oval and small ellipse, big oval and small oval long axial length
Spend identical and coincide together, the long axis length of big ellipse is 1.3 times of short axle, and small oval long axis length is short axle
1.8 times, oval long axis length is different in each sperm head compares figure, and 3~10 sperm head compares figures are distributed on fixed
The outer rim of circle of position, and the center of circle of major axis oval in each sperm head compares figure and setting circle is located on the same line.
Oval long axis length is 3.7~4.7 microns in sperm head compares figure.
It is of the present utility model further technical scheme be：Sperm head compares figure is provided with 5, is No. I sperm head respectively
Portion's compares figure, No. II sperm head compares figure, No. III sperm head compares figure, No. IV sperm head compares figure and No. V sperm head
Portion's compares figure, oval long axis length is 3.70 microns in No. I sperm head compares figure, ellipse in No. II sperm head compares figure
Circular long axis length is 3.95 microns, and oval long axis length is 4.20 microns, No. IV in No. III sperm head compares figure
Oval long axis length is 4.45 microns in sperm head compares figure, oval long axial length in No. V sperm head compares figure
Degree is 4.70 microns.
The utility model is provided with new sperm morphology measuring scale mark on eyepiece, the sperm morphology measuring scale mark be by
The setting circle sperm head compares figure different with multiple sizes, each sperm head compares figure are by the ellipse of two different length-width ratios
Circle is formed.The head size data drawn according to the eupyrene sperm after computer system analysis pap staining are：In length
Digit is 4.1 μm, and 95% fiducial limit is distinguished as 3.7~4.7；The median of width is 2.8 μm, 95% fiducial limit is distinguished as 2.5~
3.2；The median of length-width ratio is 1.5, and 95% fiducial limit is distinguished as 1.3~1.8（Data come from《World Health Organization human seminal fluid
Check and treatment of laboratory handbook》）.Major axis oval in sperm head compares figure can be determined according to sperm head length
Length is 3.7~4.7 microns, sperm head compares figure preferably then is arranged into 5, and selection I is oval in 5 figures
Major axis is 3.70 μm, and No. II oval major axis is 3.95 μm, and No. III oval major axis is 4.20 μm, No. IV oval length
Axle is 4.45 μm, and No. V oval major axis is 4.70 μm, makes the sperm head compares figure mark of length-width ratio 1.3,1.8 respectively
On a microscopical eyepiece, five figures are centered around on setting circle and can rotated, while sperm head compares figure is semi-transparent
It is bright, the diagosis of mirror form under microscope is not influenceed.
The utility model principle is similar with existing eyepiece chi mark, and the scale of straight line is replaced with eupyrene sperm head shape figure
Chi mark.The utility model can easily measure the length and width scope of sperm head, while can quickly judge the sperm
Whether head meets the length-width ratio on eupyrene sperm head, whether smooth measures sperm head, if meets radian rule, generally
Whether it is ellipse.The error of manual operation can be reduced as far as using the utility model, makes up the inaccurate of manual evaluation
Really, standard grasps the defects of inconsistent, makes the quality control of semen analysis practical.
