Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, specifically to an automatic semen sealing device for a fully automatic sperm quality analyzer. Background Technology

[0002] In recent years, the incidence of infertility has increased. According to authoritative data statistics, male and female causes are equally prevalent. In medical institutions examining male infertility, sperm morphology, concentration, motility, viability, and fragmentation rate have been verified to be related to fertility. Therefore, the testing of these indicators is crucial. Specifically, this involves collecting sperm samples, preparing relevant slides, and conducting data analysis. The samples need to be prepared into appropriate glass slides for testing. Fully automated sperm quality analyzers use a non-oil-dripping analysis method, which avoids the use of microscope oil and reduces the need for cleaning the microscope lens. Lens cleaning agents have a pungent odor, which is harmful to... The traditional method of sealing slides involves manually applying the sealing agent to the prepared sample slide using a dropper, then covering it with a coverslip and pressing it down repeatedly. This process is risky as the sealing agent has come into contact with the sample, potentially affecting the analysis results. Furthermore, sealed slides can be preserved for extended periods, which is crucial for research and data preservation. Therefore, a sealing device that can replace manual pressing is urgently needed in the market. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic semen sealing device for a fully automated sperm quality analyzer, in order to solve the risk of manual sealing where the human hand comes into contact with the sealing material and the sample, which can easily affect the sample analysis results.

[0021] like Figs. 1 to 3 The fully automated sperm quality analyzer shown includes an automatic semen sealing device, comprising a base 1, a lifting mechanism, and a pressing mechanism;

[0022] A lifting mechanism is connected to the base 1. The lifting mechanism is used to control the pressing mechanism to move up or down. The pressing mechanism is used to press the cover glass 3 placed on the slide 2.

[0023] In this embodiment, the coverslip 3 is pressed mechanically instead of manually, which avoids contact between the human hand and the sealing medium and the sample during the pressing process, and further avoids the influence of human hand contact with the sealing medium and the sample on the sample analysis results.

[0024] The lifting device includes a housing 5, a stepper motor 6, a coupling 7, a lead screw 8, a slider nut 9, and a guide mechanism. The stepper motor 6 is installed on the top of the housing 5. The output shaft of the stepper motor 6 is connected to the top of the lead screw 8 through the coupling 7. The bottom end of the lead screw 8 is rotatably connected to the bottom wall of the housing 5 through a bearing 17. A nut slider 9 is sleeved on the lead screw 8. The bottom of the nut slider 9 extends out of one end of the housing 5 and is connected to the pressing mechanism. A guide mechanism is provided between the nut slider 9 and the housing 5.

[0025] In this embodiment, the lifting mechanism has a simple structure and requires no manual operation. The rotation of the motor can control the pressing mechanism to move up or down, thereby controlling the pressing mechanism to press the cover glass 3. Automated control can be achieved by connecting the control system in the prior art to the motor.

[0026] A support column 4 is connected to the base 1, and a box 5 is connected to the support column 4.

[0027] In this embodiment, the box body 5 and the support column 4 are detachably connected, and the support column 4 is provided to support the box body 5.

[0028] The guiding mechanism includes a linear guide rail 10 vertically mounted on the outer wall of the housing 5 and a linear slider 11 that can slide linearly along the guide rail. The side of the linear slider 11 facing away from the linear guide rail 10 is connected to the nut slider 9.

[0029] In this embodiment, the guiding mechanism mainly plays a guiding role, restricting the movement of the nut slider 9 so that the nut slider 9 can only move in the vertical direction and will not rotate horizontally, thus ensuring the stable movement of the nut slider 9.

[0030] The pressing mechanism includes a slide rod 12, a slider seat 13, a slider cover 14, a slider return spring 16, and a slider 15. The top end of the slide rod 12 is connected to one end of the nut slider 9 that extends out of the housing 5, the bottom end of the slide rod 12 is connected to the slider seat 13, the bottom of the slider seat 13 is connected to the top of the slider cover 14, a slider 15 is provided inside the slider seat 13 that slides up and down along the inner wall of the slider cover 14, a slider return spring 16 is sleeved on the outer side of the top of the slider 15, and a limiting port for the bottom of the slider 15 to extend out is provided at the bottom of the slider cover 14.

[0031] In this embodiment, the size of the middle part of the slider 15 is larger than the size of the bottom part of the slider 15. The limiting port is a square limiting port. The size of the middle part of the slider 15 is larger than the size of the limiting port. The limiting port is used to limit the distance that the slider 15 moves. The slider return spring 16 is used to buffer. Under the buffering effect, the problem of damage to the cover glass 3 caused by direct contact between the slider 15 and the cover glass 3 can be reduced.

[0032] The base 1 is provided with a placement groove 101 for placing the slide 2 and the cover glass 3. The width of the placement groove 101 is adapted to the width of the cover glass 3 and the slide 2.

[0033] In this embodiment, the placement groove 101 is used to limit the position of the cover glass 3 and the glass slide 2.

[0034] Working principle: Place the glass slide 2 in the placement groove 101, place the sample and sealing material on the glass slide 2, and then place the coverslip 3 on the glass slide 2; start the motor, the motor drives the lead screw 8 to rotate, the nut slider 9 moves downward along the lead screw 8, and the nut slider 9 drives the pressing mechanism to move downward.

[0035] The slider 15 in the pressing mechanism abuts against the cover glass 3, and then, under the buffering action of the slider return spring 16, the slider 15 slowly presses down on the cover glass 3 to complete the sealing.

[0036] After the sealing is completed, the motor reverses, the lead screw 8 reverses, the nut slider 9 moves upward, and the pressing mechanism moves upward; at the same time, under the action of the slider return spring 16, the slider 15 moves downward along the inner wall of the slider cover 14 to return to its original position.

[0037] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
