Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a semen smear preparation device. Background Art

[0002] Sperm morphology analysis refers to smearing semen into a thin film, and after processing procedures such as drying, fixing, and staining, observing under an oil immersion microscope of a microscope, counting 200 spermatozoa, analyzing the morphology of spermatozoa, recording the percentage of morphologically normal spermatozoa and morphologically abnormal spermatozoa, as well as the types of abnormal spermatozoa morphologies, so as to reflect the fertility of men.

[0003] When performing sperm morphology analysis, in the prior art, semen is manually smeared on a glass slide and the semen forms a thin layer on the glass slide. Since the sperm concentration in the semen of different patients is different, when smearing to form a thin layer on the glass slide, semen with a lower sperm concentration is likely to have uneven sperm distribution after smearing, and it is often the case that multiple fields of view need to be changed to find spermatozoa when observing 200 spermatozoa later, resulting in low efficiency; after semen with a higher sperm concentration is smeared, the spermatozoa are likely to overlap, making subsequent observation inconvenient.

[0083] See Figures 1 to 9 , this embodiment provides a semen smear preparation device, including a box body 10, a first mounting seat 20, a second mounting seat 21, a pipetting device 22 and a driving device 30.

[0084] The box body 10 has a tabletop 11. The first mounting seat 20 is rotatably arranged on the tabletop 11, and the first mounting seat 20 is used for placing a glass slide. The second mounting seat 21 is arranged on the tabletop 11, and the second mounting seat 21 is used for placing a semen collection cup. The pipetting device 22 is arranged in the box body 10, and the pipetting device 22 can transfer the semen in the semen collection cup to the glass slide. The driving device 30 is used for driving the first mounting seat 20 to rotate.

[0085] In this embodiment, the pipetting device 22 transfers the semen in the semen collection cup on the second mounting seat 21 to the glass slide on the first mounting seat 20, and the driving device 30 is used to drive the first mounting seat 20 to rotate at a low speed, so that the semen on the glass slide is gradually flattened, so that the sperm in the semen are more evenly distributed on the glass slide. Even if the sperm concentration in the semen is low, the evenly distributed sperm are easier to find during subsequent observation, thus improving the observation efficiency.

[0086] In one embodiment, the semen smear preparation device further includes a controller (not shown), a third mounting seat 23, a water injection device 24 and a camera.

[0087] The controller is arranged inside the box body 10, and the controller adopts the existing technology. The third mounting seat 23 is arranged on the tabletop 11, and the third mounting seat 23 is used for placing the sperm concentration test strip. The sperm concentration test strip adopts the existing technology. After the sperm concentration test strip contacts the semen, it shows different shades of color according to the different sperm concentrations in the semen. The water injection device 24 is arranged inside the box body 10, and the water injection device 24 is electrically connected to the controller. The water injection device 24 can inject water into the semen collection cup. The camera is arranged inside the box body 10, and the camera is located above the third mounting seat 23. The camera is used for collecting the color of the sperm concentration test strip and uploading it to the controller.

[0088] The pipetting device 22 is electrically connected to the controller. The pipetting device 22 can transfer the semen in the semen collection cup to the sperm concentration test strip. The controller can control the water injection device 24 to inject water into the semen collection cup according to the color of the sperm concentration test strip uploaded by the camera. The controller can control the pipetting device 22 to transfer the semen in the semen collection cup to the sperm concentration test strip or the glass slide. Specifically, the pipetting device 22 can adopt a pipette in the existing technology. The pipetting device 22 is arranged inside the box body 10 so as to be slidable in the horizontal direction. The pipetting device 22 can move vertically, so that the pipetting device 22 can transfer the semen in the semen collection cup to the glass slide or the sperm concentration test strip. The water injection device 24 can select the combination mode of a syringe and a pushing structure in the existing technology, which will not be elaborated here. The water injection device 24 is arranged inside the box body 10 so as to be slidable in the horizontal direction, so that the water injection device 24 can move above the semen collection cup to complete the water injection.

[0089] In this embodiment, the semen collection cup loaded with semen is placed on the second mounting seat 21. The controller controls the pipetting device 22 to move above the semen collection cup to suck the semen and then move above the third mounting seat 23. The pipetting device 22 injects the sucked semen onto the sperm concentration test strip and then leaves. After the reaction time has passed, the camera uploads the image of the sperm concentration test strip into the controller. The controller determines the approximate concentration range of the semen according to the image uploaded by the camera. When the semen concentration is high, the controller controls the water injection mechanism to move above the semen collection cup to inject water and then leave. Then the pipetting device 22 (pipette) moves to the semen collection cup, and the semen in the semen collection cup is extracted and injected multiple times to achieve uniform mixing of water and semen, thereby completing the dilution of the semen. Under the control of the controller, the pipetting device 22 sucks the semen in the semen collection cup and then injects it onto the glass slide. When the first mounting seat 20 rotates, the semen can be evenly spread on the glass slide. Under the control of the controller, the high-concentration semen can be diluted, so as to reduce the situation of sperm superposition during subsequent observation.

[0090] In one embodiment, a card slot for mounting a slide is provided at the upper end of the first mounting seat 20: the upper end surface of the first mounting seat 20 is flush with the upper end surface of the slide. One end of the card slot can be open, and the slide can be inserted into the card slot from the side. Rubber can be provided on both inner walls of the card slot to increase the friction with the slide and prevent the slide from moving in the card slot when the first mounting seat 20 rotates subsequently.

[0091] The semen smear preparation device further includes a shielding ring 60 and a cleaning mechanism 70.

[0092] There are two shielding rings 60, and the two shielding rings 60 can alternately press against the slide. The cleaning mechanism 70 can clean the shielding ring 60. The diameter of the inner circle of the shielding ring 60 is smaller than the width of the slide; the driving device 30 can drive the two shielding rings 60 to alternately press against the slide.

[0093] In this embodiment, when the first mounting seat 20 rotates to spread the semen flat on the slide, the shielding ring 60 presses against the slide. The shielding ring 60 is made of rubber or other flexible materials. At this time, the semen is located inside the shielding ring 60 and is spread into a circular thin layer, thereby preventing the semen from flowing out of the first mounting seat 20.

[0094] In one embodiment, the driving device 30 includes a first rod 31, a second rod 32, a third rod 33, and a driving mechanism 34.

[0095] The first rod 31 is arranged vertically. There are two second rods 32, and the ends of the two second rods 32 are respectively connected to the upper and lower ends of the first rod 31. The end of the second rod 32 far from the first rod 31 is connected to the corresponding shielding ring 60. The end of the third rod 33 is connected to the middle of the first rod 31. The third rod 33 is horizontally slidably arranged in the box body 10, and the third rod 33 can rotate around its center line. The driving mechanism 34 is used to drive the first mounting seat 20 to rotate, and is also used to drive the third rod 33 to rotate and horizontally slide; the cleaning mechanism 70 can clean the shielding ring 60 located at the lower end. The cleaning mechanism 70 is two sets of nozzles arranged up and down in the box body 10. The nozzles can spray water. When the shielding ring 60 rotates to the lower part, the two sets of nozzles spray water to clean the shielding ring 60 from the upper and lower sides respectively. The water flowing down from the cleaning can be led out through a hole opened on the box body 10 by an external hose and centrally processed. In addition, the cleaning mechanism 70 can also be provided with a fan to blow air on the shielding ring 60 to make it dry as soon as possible. The shielding ring 60 can rotate around a fixed axis at the end of the second rod 32. Specifically, a bearing is connected to the end of the second rod 32, and the inner ring of the bearing is connected to the outer ring of the shielding ring 60. The shielding ring 60 can be horizontally slid with the third rod 33 and then be located above the slide and press against the slide.

[0096] In this embodiment, under the drive of the drive mechanism 34, the third rod 33 slides horizontally; at this time, the shielding ring 60 at the end of the second rod 32 approaches the first mounting seat 20 as the third rod 33 slides and finally lies above the first mounting seat 20, and the slide glass on the first mounting seat 20 will be pressed later. At the same time, the lower shielding ring 60 is cleaned by the cleaning mechanism 70. Then the drive mechanism 34 drives the first mounting seat 20 to rotate. Since the shielding ring 60 is pressed against the first mounting seat 20 and the slide glass, the shielding ring 60 rotates together until the semen is flattened on the slide glass. Then the drive mechanism 34 stops driving the first mounting seat 20, the first mounting seat 20 gradually stops, and the third rod 33 slides under the drive of the drive mechanism 34, so that the shielding ring 60 pressing on the slide glass gradually moves away from the first mounting seat 20. Finally, under the drive of the drive mechanism 34, the third rod 33 rotates, and the positions of the upper shielding ring 60 and the lower shielding ring 60 are interchanged, and the cleaning mechanism 70 cleans the shielding ring 60 that has just been contaminated with semen and rotated to the lower part.

[0097] In one embodiment, the drive mechanism 34 includes a connecting rod 341, a driving member 342, a driving disk 35 and a sliding column 36.

[0098] One end of the connecting rod 341 is rotatably connected to the end of the third rod 33 away from the first rod 31. The driving member 342 is fixedly connected to the end of the connecting rod 341 away from the third rod 33. A driving groove penetrating up and down is formed in the driving member 342, and the driving member 342 is integrally in an arch shape. The upper end of the driving member 342 is close to the driving disk 35, which makes the driving member 342 not rotate relative to the driving disk 35. The driving disk 35 is arranged in the box body 10, and the driving disk 35 is a disk and can be rotated by an external force. The sliding column 36 is eccentrically connected to the lower end surface of the driving disk 35, and the lower end of the sliding column 36 is in clearance fit with the driving groove. The third rod 33 is located on one side of the first mounting seat 20.

[0099] The driving groove includes an arc segment 342a and two straight segments 342b. The convex end of the arc segment 342a faces the third rod 33, and the position where the connecting rod 341 is connected to the driving member 342 corresponds to the convex part of the arc segment 342a. The two straight segments 342b are respectively communicated with the two ends of the arc segment 342a. Both of the two straight segments 342b are perpendicular to the center line of the third rod 33.

[0100] In this embodiment, when the driving disk 35 rotates by an external force, the sliding column 36 slides in the driving groove. When the sliding column 36 gradually approaches the third rod 33 during the process of following the rotation of the driving disk 35, as Figure 5, at this time, the sliding column 36 slides within the arc segment 342a of the driving groove, the connecting rod 341 will not drive the third rod 33 to slide horizontally, and the upper shielding rings 60 at this time are all away from the first mounting seat 20. As the driving disk 35 further rotates, after the sliding column 36 rotates to the position closest to the third rod 33 and then gradually moves away, until the sliding column 36 slides into the straight segment 342b of the driving groove on the other side. At this time, the sliding column 36 can drive the driving member 342 away from the third rod 33. Correspondingly, the shielding rings 60 at the upper and lower ends of the first rod 31 will move accordingly. The upper shielding ring 60 moves above the first mounting seat 20, and the lower shielding ring 60 moves to the position of the cleaning mechanism 70 to be cleaned. The design of the arc segment 342a and the straight segment 342b of the driving groove enables the connecting rod 341 not to drive the third rod 33 to slide when the sliding column 36 rotates following the driving disk 35 during a certain period of time, thus preparing for the subsequent rotation of the third rod 33 around its own center line, so that the upper and lower two shielding rings 60 can be smoothly rotated and displaced.

[0101] In one embodiment, a pulley is sleeved outside the driving disk 35.

[0102] The driving mechanism 34 further includes a driving sleeve 37 and a driving column 38.

[0103] The driving sleeve 37 is vertically arranged in the box body 10. A pulley is sleeved outside the driving sleeve 37, and the pulley sleeved outside the driving sleeve 37 and the pulley sleeved outside the driving disk 35 are driven by a belt. The driving sleeve 37 can be rotated by an external force, and the axis of the driving sleeve 37 is perpendicular to the center line of the third rod 33. The driving column 38 is rotatably arranged in the box body 10. A first hole 381 is formed in the driving column 38 along its axial direction, and the first hole 381 is in sliding fit with the third rod 33 along its axial direction. The connection modes of the driving sleeve 37 and the driving column 38 with the box body 10 are similar. Both are connected to the inner ring of a bearing, and the outer ring of this bearing is connected to the inner wall of the box body 10. The rotation of the driving sleeve 37 can drive the driving column 38 to rotate reciprocally by 180 degrees.

[0104] In this embodiment, the driving sleeve 37 drives the driving disk 35 to rotate to make the two shielding rings 60 approach or move away from the first mounting seat 20. When the sliding column 36 drives the two shielding rings 60 to be at the position farthest from the first mounting seat 20, at this time, the sliding column 36 moves within the arc segment 342a. And at this time, the driving sleeve 37 continues to rotate, the shielding rings 60 remain in place, and the driving sleeve 37 drives the driving column 38 to rotate by 180 degrees, so that the positions of the two shielding rings 60 are interchanged.

[0105] In one embodiment, the driving mechanism 34 further includes a driving rod 39, a connecting block 40, an arc-shaped block 41 and a limiting disk 42.

[0106] There are two driving rods 39, which are symmetrically arranged on both sides of the driving sleeve 37. The end of the driving rod 39 is connected to the outer wall of the driving sleeve 37, and the axis of the driving rod 39 extends along the radial direction of the driving sleeve 37; there are two connecting blocks 40, and the ends of the connecting blocks 40 are both connected to the outer wall of the driving sleeve 37. The driving rod 39 and the arc-shaped block 41 are at the same height of the driving sleeve 37.

[0107] There are two arc-shaped blocks 41, which are symmetrically arranged on both sides of the driving sleeve 37. The arc-shaped block 41 is connected to the corresponding connecting block 40. The axis of the arc-shaped block 41 is collinear with the axis of the driving sleeve 37. The distance between the arc-shaped block 41 and the outer wall of the driving sleeve 37 is less than the length of the driving rod 39. Two limiting discs 42 are coaxially connected to both ends of the driving column 38 respectively, and limiting notches 43 are respectively opened on two opposite ends of the limiting disc 42. The positions of the limiting notches 43 on the two limiting discs 42 are the same. The connection line of the two limiting notches 43 on the same limiting disc 42 can divide the limiting disc 42 into two equal halves. Viewed from the axial direction of the driving column 38, the spiral groove 44 has only half a turn.

[0108] Two intersecting spiral grooves 44 are opened on the outer wall of the driving column 38; the two ends of the spiral groove 44 are respectively communicated with the opposite-side limiting notches 43 on the two limiting discs 42; the end of the arc-shaped block 41 can slide into the limiting notch 43 of one limiting disc 42 and slide out from the limiting notch 43 of the other limiting disc 42; the end of the driving rod 39 far from the driving sleeve 37 can slide into the corresponding spiral groove 44 from the limiting notch 43 and slide out from the limiting notch 43 at the other end of the spiral groove 44. Specifically, the two spiral grooves 44 respectively correspond to the two driving rods 39. In order to make the cooperation between the driving rod 39 and the spiral groove 44 stable, one driving rod 39 is long and thin, and the corresponding spiral groove 44 is narrow and deep; the other driving rod 39 is slightly shorter and thicker, and the corresponding spiral groove 44 is wide and shallow.

[0109] In this embodiment, when the driving sleeve 37 rotates, it drives the driving rod 39 and the arc-shaped block 41 to rotate. After the driving rod 39 passes through the limiting notch 43 and enters the spiral groove 44, it drives the driving column 38 to rotate 180 degrees. Immediately afterwards, the arc-shaped block 41 passes through the limiting notch 43, which limits the driving column 38 and makes it unable to rotate anymore. After the arc-shaped block 41 leaves the limiting notch 43, the other driving rod 39 is inserted into the spiral groove 44, making the driving column 38 reverse 180 degrees. That is, the third rod 33 drives the two shielding rings 60 to move away from the first mounting seat 20 once, and the two shielding rings 60 are transposed once.

[0110] In one embodiment, a first bearing 45 is sleeved outside the first mounting seat 20. The first bearing 45 is connected to the box body 10; a second hole 12 is opened on the table surface 11. The second hole 12 is located below the first mounting seat 20.

[0111] The driving mechanism 34 further includes a motor 46, a rotating shaft 47, a friction disc 48, a transition member 49, and an electric push rod 50.

[0112] The motor 46 is fixedly connected to the box body 10. The rotating shaft 47 is axially slidably connected to the output end of the motor 46, is located inside the driving sleeve 37 and is coaxial with the driving sleeve 37. A square hole is formed in the rotating shaft 47, and the output end of the motor 46 is a square rod and is slidably matched with the square hole. The friction disc 48 is connected to one end of the rotating shaft 47 away from the motor 46, and can rise and pass through the second hole 12 to abut against the bottom of the first mounting seat 20. One end of the transition member 49 is rotatably connected to the rotating shaft 47. The electric push rod 50 is connected to the box body 10, and the output end of the electric push rod 50 is connected to the transition member 49.

[0113] In this embodiment, driven by the electric push rod 50, the transition member 49 drives the rotating shaft 47 to rise, so that the friction disc 48 abuts against the bottom of the first mounting seat 20, and then the motor 46 drives the friction disc 48 to rotate through the rotating shaft 47, thereby driving the first mounting seat 20 to rotate.

[0114] In one embodiment, a stop block 51 along its axis is connected to the inner wall of the driving sleeve 37; a driving block 52 is connected to the outer wall of the bearing; the driving block 52 can abut against the stop block 51; when the rotating shaft 47 rises, the driving block 52 gradually disengages from the stop block 51. The upper end of the stop block 51 is a tip, so that the driving block 52 will not be blocked by the upper end of the stop block 51 when moving downward.

[0115] In this embodiment, after the rotating shaft 47 rises under the drive of the electric push rod 50 to drive the first mounting seat 20 to rotate, at this time the driving block 52 disengages from the stop block 51, so that the shielding ring 60 remains stationary on the first mounting seat 20. When the rotating shaft 47 descends, the driving block 52 returns to the same level as the stop block 51. As the rotating shaft 47 rotates, the shielding ring 60 can be driven away from the first mounting seat 20 by driving the stop block 51, the driving sleeve 37, the driving disc 35 and other structures through the driving block 52 in sequence.

[0116] In one embodiment, the driving mechanism 34 further includes a sliding seat 53 and a sliding block 54.

[0117] The sliding seat 53 is provided with an upward chute, and the lower end of the chute is closed. One end of the sliding block 54 is slidably matched with the chute, and the other end of the sliding block 54 is connected to the outer ring of the first bearing 45.

[0118] In this embodiment, when the shielding ring 60 moves above the first mounting seat 20, the friction disc 48 moves upward to jack up the first mounting seat 20. The upper end of the first mounting seat 20 abuts against the shielding ring 60, realizing the pressing of the shielding ring 60 against the first mounting seat 20. At this time, the friction disc 48 rotates driven by the rotating shaft 47 to drive the first mounting seat 20 and the shielding ring 60 to rotate. After the semen is flattened, the friction disc 48 moves downward, and the first mounting disc also moves downward by a certain distance. Then, when the slider 54 abuts against the closed end of the chute, it no longer moves downward. At this time, there is a certain distance between the first mounting seat 20 and the shielding ring 60, and the subsequent movement of the shielding ring 60 will not drag the semen on the glass slide.
