Problems solved by technology

The biggest disadvantage of dip dyeing is that the former reagent can be brought into the latter reagent, the purity of the reagent is not easy to control, and it is difficult to guarantee the dyeing effect after a group of reagents are used several times because the purity cannot be guaranteed.
Frequent replacement of reagents is a big waste, and the automated dipping instrument has a large volume and a high price
Therefore, the standardization of sperm staining is currently difficult

Embodiment 1

[0014] Embodiment 1: semi-automatic sperm staining instrument, comprises rectangular base 1, is arranged on base 1 along the 3 dyeing solution containers 2 that are arranged side by side at intervals along the long side and is arranged on the padding device 3 above base 1, described The pressure dyeing device 3 includes a press plate 3.1 whose long side is horizontal to the short side of the base 1, and 3 sperm-coated glass sheets 3.1.1 arranged on the press plate 3.1. The two ends of the lower long side of the press plate 3.1 are hinged with a sliding connection device 4, so that The pressing plate 3.1 can be turned up and down and can slide back and forth along the long side of the base 1 . The staining solution container 2 includes a strip-shaped base 2.1 fixedly connected to the base 1 and three bowl-shaped liquid storage containers 2.2 arranged on the strip-shaped base 2.1. The bowl-shaped liquid storage containers 2.2 are plastic elastomers. The positions of the sperm-co...

Abstract

A semi-automatic sperm staining instrument, comprising a rectangular base, several staining solution containers arranged side by side along the long sides at intervals on the base, and a padding device arranged above the base, the padding device includes a long side and a base A pressing plate with a horizontal short side, several sperm-coated glass sheets arranged on the pressing plate, sliding connection devices hinged at both ends of the lower long side of the pressing plate, so that the pressing plate can be turned up and down and reciprocally slide along the long side of the base. The pressure dyeing method and the use of special instruments to control the time also solve the problem of easy mixing of dyes. At the same time, there are washing and air-drying devices, and the standardization of sperm staining can be achieved at a fixed room temperature. It solved the problem of standardization of sperm morphology staining and laid the foundation for the standardization of sperm morphology diagnosis.

Description

technical field [0001] The invention relates to a sperm morphology inspection device, that is, a sperm deformity rate inspection device, in particular to a sperm staining instrument. Background technique [0002] Sperm morphology examination is the inspection of sperm deformity rate, and the sperm deformity rate has great significance for reproduction. Sperm must be stained before the examination, and the staining method currently used requires the use of three reagents. Fixative solution, staining solution A, and staining solution B. The three reagents are in contact with the slides with sperm attached in sequence. Before using the second reagent, it is necessary to minimize the adhesion of the former reagent, but it cannot be contacted with water-absorbing objects. slides. The contact time of each reagent has a standard, because the length of the staining agent contact time affects the staining effect, and the staining effect has a greater impact on the diagnosis of sper...
