Description

Sperm analysis auxiliary device Technical Field The utility model relates to the technical field of sperm analysis, in particular to a sperm analysis auxiliary device. Background Semen analysis is often used in assessing male fertility. The method is characterized in that the glass slide and the cover glass are of a separated structure, the cover glass is thinner and smoother and is easy to fall, so that the cover glass cannot be used due to pollution, the cover glass also has a certain weight, the cover glass is placed on the semen, the semen thickness cannot be controlled, the cover glass cannot be ensured, the situation that one end of the semen is thicker and the other end of the semen is thinner is easy to occur, the semen thickness is different, the number of sperms in a unit area is different, and the measuring result of the number and density of the sperms is influenced, namely, the semen of the same patient is possibly measured for more than two times, the situation that the measuring result is not identical due to the difference of the semen thickness between different glass slides and the cover glass is likely to occur, in addition, when the thickness is thinner, the cover glass has compression, the sperm is influenced, and the observation result of the motility of the sperm is also influenced. Disclosure of utility model The utility model aims to provide a sperm analysis auxiliary device which is convenient to operate and accurate in sperm analysis result. In order to achieve the purpose, the sperm analysis auxiliary device comprises a glass slide and a cover glass, wherein the cover glass is arranged right above the middle of the glass slide, the length of the cover glass is smaller than that of the glass slide, the width of the cover glass is smaller than that of the glass slide, four corners below the cover glass are connected with the glass slide through connecting columns, and the distance between the lower end face of the cover glass and the upper end face of the glass slide is 5.5-6 mu m. The utility model further provides a technical scheme that the upper end face or the lower end face of the cover glass is provided with longitudinal lines and transverse lines which are parallel to each other, and the longitudinal lines and the transverse lines are perpendicular to each other. The utility model can further comprise the following technical scheme that the distance between the adjacent longitudinal lines and the adjacent transverse lines is 180-500 mu m. The utility model further provides a technical scheme that a semen storage cavity close to one end of the cover glass is arranged on the glass slide. The semen to be detected is added into the semen storage cavity in a delivering way, and the semen higher than the gap part between the glass slide and the cover glass enters between the glass slide and the cover glass under the action of siphoning and gravity to form a semen layer with consistent thickness, so that the superfluous semen is reserved in the semen storage cavity, and pollution caused by flowing out of the glass slide is avoided. The utility model further comprises the following technical scheme that the volume of the semen storage cavity is 100-200 microliters. When the sperm analysis auxiliary device is used, semen is directly dripped into one end of the cover glass or the semen storage cavity, the operation is convenient, the semen flows into the space between the cover glass and the glass slide under the action of siphoning and gravity to form a sperm layer with consistent thickness, the number, the concentration and the like of the sperms are accurately calculated, the motility of the sperms is not influenced, the observation result of the sperm motility is accurate, in addition, the number, the concentration, the movement rate, the motility and other data of the sperms in a unit area can be calculated according to a plurality of observation windows formed by longitudinal lines and transverse lines, then the average value of corresponding numerical values of the observation windows can be calculated, and the measurement result is more reasonable and accurate. In summary, the sperm analysis auxiliary device has the advantages that the structure is simple, the operation is convenient, the thickness of the sperm between the glass slide and the cover glass is consistent by setting the height of the gap between the glass slide and the cover glass, the sample amount of the sperm can be automatically and quantitatively detected, meanwhile, the free swimming of the sperm can be ensured, the detection personnel only need to drop the sperm to be detected into one end of the cover glass or the sperm storage cavity, the operation is simplified, the manual operation error is avoided, various parameter indexes of the sperm are accurately measured and calculated, and the sperm analysis and measurement result is accurate.
