Description

Technical Field

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

[0002] According to authoritative big data statistics, male and female factors each account for half of the infertility cases. 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 quite important. Specifically, sperm samples are collected for slide preparation and data analysis. The samples need to be prepared into appropriate glass slides before testing. The fully automated sperm quality analyzer uses a non-dripping oil 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 and are not human-friendly. Oil detection requires sealing slides with sealing agents and coverslips. Sealed slides can then be automatically analyzed. The normal sealing process involves manually applying the sealing agent to the prepared sample slide using a dropper, covering it with a coverslip, and pressing it down manually multiple times. During this process, the hands can easily get the sealing agent stuck to them, posing a risk as the sealing agent has been in contact with the sample and could potentially affect the analysis results. Furthermore, sealed slides allow for long-term preservation, which is of practical significance for research and data storage. Therefore, a sealing device that can replace manual pressing is urgently needed in the market. Utility Model Content

[0024] like Figures 1 to 4 The manual semen sealing device for a fully automated sperm quality analyzer shown includes a base 1, a lifting mechanism, and a pressing mechanism;

[0025] A lifting mechanism is provided above 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.

[0026] In this embodiment, a mechanical bag is used to press the coverslip 3 instead of manually, which avoids the possibility of human hands coming into contact with the sealing material and the sample during the pressing process, and thus avoids the influence of human hands coming into contact with the sealing material and the sample on the sample analysis results.

[0027] The lifting mechanism includes a housing 5, a cam 7, a slide rod 9, and a slide rod return spring 10. A removable housing cover 5 is provided on one side of the housing 5. The cam 7 is provided inside the housing 5. One side of the cam 7 is connected to a pressure rod 6 provided on the outside of the housing 5 via a connecting rod. The connecting rod is rotatably connected to the wall of the housing 5 via a bearing. The slide rod 9 is slidably connected inside the housing 5. The slide rod return spring 10 is sleeved on the slide rod 9. A first limiting hole is provided at the bottom of the housing 5 for the bottom end of the slide rod 9 to pass through. The bottom end of the slide rod 9 is connected to the pressing mechanism. The cam 7 and the slide rod return spring 10 cooperate to control the position of the slide rod 9 in the vertical direction, thereby controlling the position of the pressing mechanism in the vertical direction.

[0028] In this embodiment, the lifting mechanism has a simple structure and is easy to operate. The rotation of the pressure rod 6 can control the pressing mechanism to move up or down, thereby controlling the pressing mechanism to press the cover glass 3.

[0029] A support column 4 is connected to the base 1, and a box 5 is connected to the support column 4.

[0030] 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.

[0031] The housing 5 is provided with a slide rail for vertically guiding the slide rod 9. The slide rod 9 moves vertically along the slide rail. The upper diameter of the slide rod 9 is larger than the lower diameter of the slide rod 9, and the diameter of the first limiting hole is smaller than the upper diameter of the slide rod 9.

[0032] In this embodiment, the upper diameter of the slide rod 9 is larger than the diameter of the first limiting hole to limit the movement distance of the slide rod 9 and prevent the slide rod 9 from detaching from the housing 5; the slide rod return spring 10 is set at the lower part of the slide rod 9, the top end of the slide rod return spring 10 abuts against the bottom surface of the upper part of the slide rod 9, and the bottom end of the slide rod return spring 10 abuts against the bottom of the housing 5. The slide rod return spring 10 is used to move the slide rod 9 upward and reset it under the action of elastic force.

[0033] The pressing mechanism includes a slider seat 11, a slider cover 12, a slider return spring 13, and a slider 14. The top of the slider seat 11 is connected to the bottom of the slider rod 9, and the bottom of the slider seat 11 is connected to the top of the slider cover 12. A cavity is provided between the slider seat 11 and the slider cover 12. A slider 14 is provided in the cavity and slides up and down along the inner wall of the slider cover 12. A slider return spring 13 is sleeved on the outer side of the top of the slider 14. A second limiting port for the bottom of the slider 14 to extend downward is provided at the bottom of the slider cover 12.

[0034] In this embodiment, the size of the middle part of the slider 14 is larger than the size of the bottom part and the size of the top part of the slider 14. The second limiting port is a square limiting port. The size of the middle part of the slider 14 is larger than the size of the second limiting port. The second limiting port is used to limit the distance the slider 14 moves. The slider return spring 13 is used to buffer. Under the buffering effect, the force of direct contact between the slider 14 and the cover glass 3 can be reduced, reducing the problem of damage to the cover glass 3.

[0035] 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.

[0036] In this embodiment, the placement groove 101 is used to limit the position of the cover glass 3 and the glass slide 2, thereby reducing the problem of displacement of the cover glass 3 and the glass slide 2 during the pressing process.

[0037] 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; rotate the pressure rod 6 downward, the pressure rod 6 drives the cam 7 to rotate downward, the far end of the cam 7 presses down on the slide rod 9, the slide rod 9 slides down, and the bottom end of the slide rod 9 drives the pressing mechanism to move downward.

[0038] The slider 14 on the pressing mechanism contacts the cover glass 3. Under the action of the slider return spring 13 at the top of the slider 14, the slider 14 gradually applies downward pressure to the cover glass 3, pressing the cover glass 3 to complete the sealing.

[0039] Rotate the pressure rod 6 upwards, and the far end of the cam 7 moves upwards away from the slide rod 9. Under the action of the slide rod return spring 10, the slide rod 9 moves upwards, and the pressing mechanism moves upwards away from the cover glass 3. At the same time, under the action of the slider return spring 13, the slider 14 in the pressing mechanism moves downwards along the inner wall of the slider cover 12.
