Abstract

The utility model designs a counting plate for sperms, which is suitable for the use of counting sperm density and analyzing sperm survival ratio and sperm movement and especially suitable for the use in wide base course institutions; the utility model is composed of a bottom board 1 and a cover plate, wherein, the centre of the bottom board 1 is an object holding platform 3, a position fixing circle 6 is curved on the centre of the platform, and a counting grid 7 is curved on the centre of the circle; the utility model is characterized in that the bottom board 1 is composed of glass, the periphery of the platform is provided with three polishing ball struts 4 whose height are equal, and the cover plate is formed by gluing an annular glass 8 and a thin sheet.

Description

The sperm count plate

The utility model relates to a kind of medical test instrument, is a kind of sperm count plate specifically.

It is year historical that traditional blood cell counting plate is used for surplus the semen efamination existing 50, owing to only can count sperm concentration, degree of accuracy is low, has been not suitable for the requirement of modern andrology development.Israel scholar in 1978 has invented Makler sperm count plate and has been exclusively used in semen analysis, and this tally is easy and simple to handle, fast, the degree of accuracy height, accuracy is good, generally uses abroad.But owing to cost an arm and a leg, need use having on the advanced microscope of telephoto lens, be difficult to promote the use of in China.

The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of sperm concentration counting that is applicable to, sperm motility rate and movement velocity analysis particularly are fit to the sperm count plate that the vast grass-roots unit of China uses.

The utility model technical solution:

A kind of sperm count plate of forming by base plate 1, cover plate, wherein base plate 1 center is an article carrying platform 3, positioning circle 6 is carved with in platform central authorities, circle center is carved with counting grid 7, it is characterized in that base plate 1 is made up of glass, 3 contour polishing ball pillars 4 are arranged around the platform, and cover plate is by ring glass 8 and 9 bonding compositions of thin slice.

Advantage of the present utility model:

This sperm count plate is easy and simple to handle, practical, is convenient to detect, and is suitable for observing under all microscope 40 * object lens, and degree of accuracy is identical with external like product, but cost is low, is easy to promote the use of at home.

Fig. 3 is the utility model platform enlarged diagram.

Fig. 4 is the utility model cover plate synoptic diagram.

Below in conjunction with accompanying drawing the utility model is further described:

It earlier is the glass blocks (base plate 1) that the optical glass of 7mm is divided into 75 * 35mm size with thickness; On base plate 1, grind wide 15mm with the husky abrasive tool of Buddha's warrior attendant, external diameter 32mm, internal diameter 17mm, the circular groove 2 of dark 5.5mm grinds the article carrying platform 3 that diameter is 8.5mm in base plate central authorities, and the edge is slightly outward-dipping; At a distance of 120 ° place with the Buddha's warrior attendant sand borer head hole that to get out 3 diameters be 2mm; The bar shaped jewel is divided into the square that the length of side is 2.5mm, and by angle lap, fine emery powder stream is worn into the ball pillar 4 that polishes a gem that diameter is 2.2mm again; With diameter is that the carbon-point of 1.9mm places in 3 holes, puts the jewel ball on the hole, uses adhesive, with the careful peak of adjusting 3 jewel balls of survey instrument, makes it all exceed central platform 10 μ m in the cementation process; Grinding diameter in the base plate bottom surface is 18mm, and the cambered surface 5 of dark 0.5mm is to reduce the wearing and tearing at printing opacity place, center; Wear into external diameter 30mm with simple glass, internal diameter 20mm, the ring glass 8 of thick 4mm is worn into the thin slice 9 of 0.35～0.37mm with potash glass, and the depth of parallelism is 00.02mm, with the two bonding composition cover plate; Be carved with a diameter 3mm in base plate article carrying platform central authorities, live width 0.5mm is divided into the positioning circle 6 of 4 sections compositions, and circle center is carved with 1 * 1mm ²Counting grid 7, be divided into 100 little lattice, the line width of grid＜1.5 μ m adopts the photocopying chromium plating to duplicate and forms.
