Description

Technical Field

[0001] This utility model relates to the field of sperm preparation technology, specifically to a sperm morphology observation and preparation device. Background Technology

[0002] In existing technologies, the methods for preparing slides for sperm morphology observation are very traditional, mainly the scraping method and the push-pull method. The scraping method involves using a scraper or other tools to thin the semen drop onto a glass slide, making it easier for microscopes or analytical equipment to clearly observe the sperm. The push-pull method is similar to the scraping method. A glass slide with the semen drop is placed flat on a table, and another glass slide is held at approximately a 45-degree angle to the first slide. The slide is then gradually pulled or pushed until the semen is thinned. This method requires a high level of skill from the operator, as it is difficult to control the pressure and the thickness of the semen. If the slide is too thick, the sperm overlaps, hindering the observation of sperm morphology. Some manufacturers have automated the push-pull method for sperm preparation. However, these methods are complex to operate and have obvious drawbacks. During the scraping or pushing-pull process, some sperm are injured, such as the head or tail. This inevitably increases the incidence of sperm abnormalities such as head damage, tail breakage, and tail dismantling. As a result, the detected sperm abnormality rate deviates from the true abnormality rate and does not reflect the actual abnormality rate of the sperm. Utility Model Content

[0003] The present invention provides a sperm morphology observation slide preparation device to solve the problem that sperm may be damaged during the existing slide preparation process.

[0004] To achieve the above objectives, this utility model provides a sperm morphology observation slide preparation device, including a slide preparation frame with a first cavity inside;

[0005] A liquid inlet rack is disposed on the slide preparation rack. The liquid inlet rack has a second cavity that communicates with the first cavity, and a liquid inlet that communicates with the second cavity is provided on one side of the liquid inlet rack.

[0006] An absorbent pad is provided with absorbent holes. The absorbent pad is disposed in the first cavity, and the absorbent holes correspond to the liquid inlet.

[0007] A glass slide is placed below the absorbent pad.

[0008] Preferably, in the above technical solution, a padding paper is provided at the bottom of the glass slide.

[0009] Preferably, in the above technical solution, the absorbent pad is made of absorbent material.

[0010] Preferably, in the above technical solution, the absorbent pad is made of absorbent paper.

[0011] Preferably, in the above technical solution, one side of the film preparation frame is provided with an assembly port communicating with the first cavity.

[0012] Preferably, in the above technical solution, the width of the assembly opening is slightly larger than the width of the absorbent pad, the glass slide, and the padding paper.

[0013] Preferably, in the above technical solution, the length of the absorbent pad and the glass slide is greater than the length of the first cavity.

[0014] Preferably, in the above technical solution, the diameter of the water absorption hole is smaller than the width of the glass slide.

[0015] Preferably, in the above technical solution, the film preparation rack and the liquid inlet rack are made of transparent material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, the sperm morphology observation slide preparation device contains a mixture of diluent and semen. The mixture enters through the inlet of the inlet rack, passes through the second cavity and the absorbent hole, and finally flows onto the slide. The mixture slowly diffuses to the periphery of the slide, while the absorbent pad on the slide continuously absorbs the liquid in the mixture. After the liquid is absorbed, the sperm remains. At this point, the sperm are dispersed and distributed on the slide. This not only achieves rapid slide preparation but also minimizes sperm damage during the slide preparation process, solving the problem of sperm damage during existing slide preparation processes. This allows for a more accurate reflection of the true sperm deformity rate.

[0018] 2. The bottom of the glass slide in this utility model is provided with padding paper, which can protect the glass slide to a certain extent so that it will not break when subjected to external impact. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0026] like Figures 1-2 As shown, the sperm morphology observation slide preparation device of this embodiment includes: a slide preparation frame 1, a first cavity 10, an assembly port 11, a pad paper 2, a glass slide 3, an absorbent pad 4, an absorbent hole 40, a liquid inlet frame 5, a second cavity 50, and a liquid inlet 51.

[0027] Continue to refer to Figures 1-2The slide holder 1 has a first cavity 10 and an assembly port 11 inside. The first cavity 10 is connected to the assembly port 11. The absorbent pad 4, the glass slide 3, and the padding paper 2 can all enter and be installed in the first cavity 10 through the assembly port 11. The absorbent pad 4 is located on the glass slide 3. The absorbent pad 4 is preferably made of absorbent material, such as absorbent paper. To facilitate the placement and removal of the absorbent pad 4 and the glass slide 3, the length of the absorbent pad 4 and the glass slide 3 is greater than the length of the first cavity 10. The padding paper 2 is located at the bottom of the glass slide 3 to protect the glass slide 3 from breakage. In this embodiment, the liquid inlet rack 5 is installed on the slide holder 1. The liquid inlet rack 5 has a second cavity 50 inside that is connected to the first cavity 10. One side of the liquid inlet rack 5 has a liquid inlet 51 that is connected to the second cavity 50. The absorbent pad 4 has a water absorption hole 40 corresponding to the liquid inlet 51, and the diameter of the water absorption hole 40 is smaller than the width of the glass slide 3.

[0028] In addition, the slide preparation rack 1 and the liquid inlet rack 5 are made of transparent material, allowing for clear observation of the slide preparation process.

[0029] Working principle: Before slide preparation, the absorbent pad 4, glass slide 3, and padding paper 2 are installed into the first cavity 10. The liquid inlet rack 5 is installed on the slide preparation rack 1. The concentrate and diluent are then mixed evenly. The mixture is drawn up using a pipette or a carrier with the same function and injected onto the glass slide 3 through the pipette. The mixture will flow from the inlet 51 through the second cavity 50 and the absorbent hole 40, and finally onto the glass slide 3. Due to the natural flow characteristics of liquids, the mixture will slowly spread to the periphery of the glass slide 3. As the liquid is absorbed, the absorbent pad 4 on the slide 3 continuously absorbs the liquid in the mixture. After the liquid is absorbed, the sperm remains and can then be distributed on the slide 3. The liquid feeding rack 5, absorbent pad 4, and slide 3 are then removed in sequence. At this point, a sperm morphology observation slide is ready. There are no large movements such as pushing or pulling during the preparation process. This not only solves the problem of sperm damage in the existing slide preparation process, but also allows the operator to only add liquid during the preparation process. It is simple, efficient, and low-cost, and deserves to be widely promoted.

These descriptions are not intended to limit the present invention to the precise forms that can be disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
