Description

Technical Field

[0002] Mastitis is one of the common mammary gland diseases in dairy cows. It is mainly manifested as inflammation of the mammary gland. In severe cases, it can cause swelling of the cow's udder, abnormal milk secretion, and even affect the quality of dairy products, causing economic losses. According to clinical observations, mastitis is usually caused by pathogenic microorganisms (such as bacteria, viruses, fungi, etc.), among which bacterial infection is the most common cause of the disease. Common pathogenic bacteria include Escherichia coli, Staphylococcus, Streptococcus, etc. These pathogenic microorganisms enter the mammary gland through damage to the nipple or mammary gland, triggering an inflammatory response, leading to mammary gland dysfunction and decreased milk quality. In severe cases, it may cause permanent damage to the cow's udder.

[0024] In this embodiment, a bracket 13 is fixedly installed on the upper surface of the workbench 1, and a discharge pipe 15 is fixedly installed on the lower surface of the bracket 13 near the turntable 3.

A limiting sleeve 17 is fixedly installed on the upper surface of the bracket 13, and a slide plate 16 is slidably installed on the inner wall of the limiting sleeve 17. A drop hole 19 is penetrated through the outer surface of the slide plate 16 near one end of the sample barrel 14, and the discharge end of the sample barrel 14 is abutted against the upper surface of the slide plate 16, and the discharge pipe 15 is connected with the discharge end of the sample barrel 14 through the drop hole 19.

[0025] The first pulley 9 is driven to rotate by the second driving motor 6, and the first pulley 9 drives the second pulley 10 to rotate through the belt 11, and the second pulley 10 drives the turntable 18 to rotate through the rotating shaft 12. The turntable 18 drives the slide plate 16 to slide back and forth intermittently through the cam groove 20 and the guide column 21, and drives the drop hole 19 to be intermittently connected with the sample cylinder 14 and the discharge pipe 15 through the slide plate 16. Through this device, the pathogen tissue block mixed liquid is intermittently and quantitatively dropped onto the upper surface of the slide glass 29, and the second clamping plate 38 and the first clamping plate 37 are alternately matched, so that the slide glass 29 is conveniently placed on the upper surface of the turntable 3. Through the up and down rotation of the rotating rod 2705, the rubber head 2706 drives the cover glass to slowly tilt and cover the slide glass 29. When detecting pathogen tissue blocks through this device, there is no need to manually drip the pathogen tissue block mixed liquid onto the slide glass 29, and then cover it with a cover glass and place it under the electron microscope 23 for observation. When batch testing is performed, the detection efficiency is greatly improved.

[0026] In this embodiment, a first storage box 26 is fixedly installed on the upper surface of the workbench 1. The first storage box 26 is tilted. A plurality of cover glasses are slidably installed on the inner wall of the first storage box 26. One end of the first storage box 26 close to the turntable 3 is lower than the other end. A step groove 2602 is provided on the bottom wall of the first storage box 26 close to the turntable 3. A right-angle stopper 2601 is fixedly installed on the upper surface of the first storage box 26 close to the turntable 3. A column 33 is fixedly installed on the upper surface of the mounting plate 2. The column 33 is arranged on the rotating cylinder 30. 1, a slide 31 is fixedly installed on the top of the column 33, a dovetail slide groove 3201 is provided on the upper surface of the slide 31, a first dovetail slider 3203 is slidably installed on the inner wall of the dovetail slide groove 3201, a mounting rod 2704 is fixedly installed on the end of the first dovetail slider 3203 close to the first storage box 26, a straight groove is provided on the lower surface of the mounting rod 2704, a rotating rod 2705 is rotatably installed between the inner walls of the straight groove, and a rubber head is fixedly installed on the end of the rotating rod 2705 close to the first storage box 26 2706, a torsion spring 2708 is provided at the fulcrum of the rotating rod 2705 for rotation installation, a liquid storage cylinder 27 is fixedly installed on the upper surface of the mounting rod 2704, a sealing cover is provided on the top of the liquid storage cylinder 27, a nozzle 2707 is fixedly installed on the liquid outlet end of the liquid storage cylinder 27 through the lower surface of the mounting rod 2704, a compression tube 2701 is fixedly installed on the circumferential outer surface of one side of the liquid storage cylinder 27, the compression tube 2701 is inclined and connected to the inside of the liquid storage cylinder 27, and a movable spring 2701 is slidably installed on the inner wall of the compression tube 2701 Plug 2702, a connecting rod 2703 is rotatably mounted on the lower surface of the piston 2702, the bottom end of the connecting rod 2703 is rotatably mounted on the upper surface of the rotating rod 2705, a driving gear 32 is rotatably mounted on the upper surface of the slide 31, a rack 3202 is fixedly mounted on the other end of the first dovetail slider 3203, the rack 3202 is meshed with the driving gear 32, and a one-way air inlet nozzle is provided on the sealing cover, so that when the piston 2702 moves downward, external air can enter the interior of the liquid storage cylinder 27 through the one-way air inlet nozzle.

[0027] The movement of the first dovetail slider 3203 drives the mounting rod 2704 to move, and the mounting rod 2704 drives the rotating rod 2705 to move close to the first storage box 26, and the rotating rod 2705 drives the rubber head 2706 to abut against the outer surface of the cover glass. Because there is an inclined angle between the plane of the cover glass and the rotating rod 2705, when the mounting rod 2704 continues to move close to the first storage box 26, the rotating rod 2705 will rotate downward, so that the rubber head 2706 pushes the cover glass downward to slide into the step groove 2602. At this time, the top of the cover glass leaves the right-angle stopper 2601, and when the first dovetail slider 3203 moves in the opposite direction, the mounting rod 2704 moves away from the first storage box 26, and the rubber head 2706 will slowly reset under the force of the torsion spring 2708, and then leave the cover glass. The surface of the slide is not driven upward because the torsion spring 2708 has a small effect. At the same time, when the rotating rod 2705 is reset and rotated upward, the piston 2702 is driven by the connecting rod 2703 to pressurize the interior of the liquid storage cylinder 27, so that the physiological saline inside the liquid storage cylinder 27 is added to the slide 29 from the nozzle 2707. When the rotating rod 2705 is completely reset, the rubber head 2706 leaves the cover glass. Because the cover glass is tilted at the beginning, the cover glass will slowly leave the rubber head 2706. As the rubber head 2706 tilts and covers the slide 29, the pathogen tissue block mixed liquid is covered. Through this device, the cover glass can be tilted and covered on the slide 29 to avoid bubbles between the cover glass and the slide 29, so that the subsequent electron microscope 23 can observe more clearly.

A spring 3804 is sleeved on the outer surface of the second square sliding rod 3802, and the spring 3804 is arranged between the second retaining ring 3803 and the second sliding sleeve 3801. Two second driving columns 3805 are symmetrically fixedly installed on the upper surface of the second dovetail slider 3204. The tops of the two second driving columns 3805 are provided with second bevels. The other end of the square slide bar 3802 is provided with a second chamfer matching the second chamfer, the distance between the first chamfer and the first chamfer is smaller than the distance between the second chamfer and the second chamfer, and the opening directions of the first chamfer and the second chamfer are opposite, and a rubber pad is provided on the outer surface of the first clamping plate 37 near the clamping mouth, and the other end of the second dovetail slider 3204 is also fixedly installed with a rack 3202, and the rack 3202 is meshed with the driving gear 32, and a transmission shaft 34 is fixedly installed on the lower surface of the rotation center of the driving gear 32, and the transmission shaft 34 is inserted in, and a first driving motor 4 is fixedly installed on the lower surface of the mounting plate 2, and the output end of the first driving motor 4 passes through the upper surface of the mounting plate 2 and is fixedly installed with the rotation center of the transmission shaft 34.

[0029] The first driving motor 4 drives the driving gear 32 to rotate forward and reverse through the transmission shaft 34. When the driving gear 32 rotates forward, the two racks 3202 respectively drive the first dovetail slider 3203 and the second dovetail slider 3204 to move away from each other, and the movement of the second dovetail slider 3204 drives the first driving column 3705 to move toward the second storage box 36. The first driving column 3705 drives the two first square sliding bars 3702 to move toward each other through the first bevel and the first chamfer. Because the first square sliding bars 3702 and the first clamping plate 37 are fixedly connected, the two first square sliding bars 3702 drive the first clamping plate 37 to clamp the slide 29 inside the second storage box 36, leaving only the most The glass slide 29 below is not clamped. While the glass slide 29 is clamped, the second dovetail slider 3204 continues to move, driving the second driving column 3805 to move toward the second storage box 36. The second driving column 3805 drives the two second square slide bars 3802 to move away from each other through the second bevel and the second chamfer. Because the second square slide bars 3802 are fixedly connected to the second clamping plate 38, the two second square slide bars 3802 drive the two second clamping plates 38 to move away from each other, so that the glass slides 29 carried on the upper surfaces of the two second clamping plates 38 fall into the right-angle positioning grooves of the two limiting columns 2804. This device makes it easy to place the glass slide 29 on the upper surface of the turntable 3. The movement sequence of first clamping of the first clamping plate 37 and then releasing of the second clamping plate 38 in the present device is achieved by setting the relative spacing between the first bevel angle and the first chamfer angle to be smaller than the relative spacing between the second bevel angle and the second chamfer angle. Before the first driving column 3705 moves close to the second storage box 36, the force of the tension spring 3704 causes the two first square sliding bars 3702 to be pulled apart from each other by a certain distance, so that the two first square sliding bars 3702 drive the first chamfer angles at their ends to be staggered by a certain distance from the first bevel angles at the top ends of the two first driving columns 3705, and similarly, before the second driving column 3805 moves close to the second storage box 36, the force of the spring 3804 causes the two second square sliding bars 3802 to be close to each other by a certain distance, so that the two second square sliding bars 3802 drive the second chamfer angles at their ends to be staggered by a certain distance from the two first The second bevels at the top ends of the two driving posts 3805 are staggered with each other for a distance, and when the first driving post 3705 and the second driving post 3805 move close to the second storage box 36, the first bevel at the top end of the first driving post 3705 will partially contact the first chamfer at the end of the first square slide bar 3702 for a distance, and as the contact area between the first bevel and the first chamfer becomes larger and larger, the first square slide bar 3702 will drive the two first clamping plates 37 to move closer to each other, so that they first clamp the glass slide 29 above the glass slide 29 to be released; then, the second bevel at the top end of the second driving post 3805 will partially contact the second chamfer at the end of the second square slide bar 3802 for a distance, and as the contact area between the second bevel and the second chamfer becomes larger and larger, the second square slide bar 3802 will drive the two second clamping plates 38 to move away from each other, so that they release the glass slide 29 to be released; In addition, a rubber pad is provided on the outer surface of the first clamping plate 37 near the clamping opening, so that after the first clamping plate 37 clamps the glass slide 29, the elastic compression of the rubber pad ensures that the first clamping plate 37 has space to move. Through this arrangement, after the first clamping plate 37 is clamped, the second clamping plate 38 can have space to loosen.

[0030] In this embodiment, a discharge plate 24 is fixedly installed on the upper surface of the workbench 1 relative to the bracket 13, and a discharge trough matching the glass slide 29 is opened on the upper surface of the discharge plate 24. An electric telescopic rod 30 is fixedly installed on the side of the slide 31 close to the discharge plate 24. A mounting table 22 is fixedly installed on the upper surface of the workbench 1 close to the discharge plate 24. An electron microscope 23 is fixedly installed on the upper surface of the mounting table 22, and the bottom end of the electron microscope 23 passes through the lower surface of the mounting table 22. Two electric telescopic pressure heads 25 are symmetrically fixedly installed on the lower surface of the mounting table 22, and the two electric telescopic pressure heads 25 are arranged above the two ends of the glass slide 29.

[0031] When the turntable 3 rotates, it drives the glass slide 29 to move to the bottom of the electron microscope 23, and the glass slide 29 is pressed down by the electric telescopic pressure head 25 to prevent it from moving around. This device facilitates the detection of the pathogenic tissue block mixed liquid on the upper surface of the glass slide 29. When the L-shaped plate 2802 moves to the position of the discharge plate 24, the sliding column 2803 is located inside the lower groove of the driving groove 2801. At this time, the two limit columns 2804 retract into the inside of the turntable 3. This arrangement makes it easy for the electric telescopic rod 30 to push out the detected glass slide 29.

[0032] In this embodiment, the rubber pad is provided so that the first clamping plate 37 has an elastic compression distance, so that the first clamping plate 37 clamps the glass slide 29 first and then the second clamping plate 38 releases it.

[0033] In this embodiment, Fig.15 2706, and the state Ⅰ represents that the rubber top 2706 has just contacted with the surface of the cover glass. The state Ⅱ represents that when the rubber top 2706 continues to contact with the surface of the cover glass, due to the inclined angle between the plane of the cover glass and the rotating rod 2705, the rubber top 2706 will move downward along the inclined angle. The cover glass is pushed downward into the step groove 2602 by the downward rotation of the rubber top 2706. At the same time, the rotating rod 2705 rotates downward, so that the rotating rod 2705 drives the piston 2702 to move downward through the connecting rod 2703. When the piston 2702 moves downward, the liquid storage cylinder 27 inhales air through the one-way air inlet nozzle at the top. The air enters the interior of the liquid storage cylinder 27; State III represents the process of the rubber head 2706 returning to its original position. When the rubber head 2706 starts to move away from the first storage box 26, the rubber head 2706 will drive the rotating rod 2705 to gradually rotate upward to restore to a horizontal state. At this time, the rotating rod 2705 drives the piston 2702 to move upward through the connecting rod 2703. The piston 2702 will squeeze the saline solution inside the liquid storage cylinder 27. The saline solution is sprayed from the nozzle 2707 onto the slide glass 29. At the same time, when the rubber head 2706 starts to move away from the first storage box 26, the cover glass will pour onto the rubber head 2706, and then as the rubber head 2706 leaves, the cover glass will cover the slide glass 29.

[0034] In this embodiment, it should be noted that the number of radial grooves of the driven sheave 8 is the same as the number of light-transmitting holes 302 , and a light source is disposed on the inner wall of the light-transmitting hole 302 .

[0035] It should be noted that when the present invention is used, the testing personnel add the mixed liquid of the broken pathogenic tissue block into the interior of the sample tube 14, and then sequentially place the slides 29 into the interior of the second storage box 36, at which time the slides 29 will sequentially fall on the upper surface of the second clamping plate 38, and then sequentially place the cover glass into the interior of the first storage box 26, and place a pressing block on the upper surface of the top cover glass to facilitate the pressing of the cover glass to move; The active dial 7 is driven to rotate by the second driving motor 6, and the active dial 7 drives the driven groove wheel 8 to rotate intermittently, and the driven groove wheel 8 drives the second gear 304 to rotate intermittently, and the second gear 304 drives the turntable 3 to rotate intermittently through the first gear 303 and the rotating cylinder 301, and the turntable 3 drives the sliding column 2803 to slide along the driving groove 2801 through the L-shaped plate 2802. When the L-shaped plate 2802 moves to the position of the discharge plate 24, the sliding column 2803 is located inside the lower groove of the driving groove 2801. At this time, the two limiting columns 2804 are retracted into the inside of the turntable 3. Through this arrangement, it is convenient for the electric telescopic rod 30 to push out the tested slide 29; when the sliding column 2803 is located inside the upper groove of the driving groove 2801, the two limiting columns 2804 extend out of the surface of the turntable 3, and the right-angle positioning grooves of the two limiting columns 2804 are used to limit the slide 29 to prevent it from shaking left and right; When the turntable 3 stops rotating, the first pulley 9 is driven to rotate by the second driving motor 6, the first pulley 9 drives the second pulley 10 to rotate through the belt 11, the second pulley 10 drives the turntable 18 to rotate through the rotating shaft 12, the turntable 18 drives the slide plate 16 to slide back and forth intermittently through the cam groove 20 and the guide column 21, and the drop hole 19 is driven by the slide plate 16 to be intermittently connected with the sample cylinder 14 and the discharge pipe 15, and the pathogen tissue block mixed liquid is intermittently and quantitatively dropped onto the upper surface of the slide glass 29 through this device, which is convenient for subsequent detection; When the turntable 3 stops rotating, the first driving motor 4 is controlled to drive the driving gear 32 to rotate forward and reverse through the transmission shaft 34. When the driving gear 32 rotates forward, the two racks 3202 respectively drive the first dovetail slider 3203 and the second dovetail slider 3204 to move away from each other, and the movement of the second dovetail slider 3204 drives the first driving column 3705 to move close to the second storage box 36. The first driving column 3705 drives the two first square sliding bars 3702 to move close to each other through the first bevel and the first chamfer. Because the first square sliding bars 3702 and the first clamping plate 37 are fixedly connected, the two first square sliding bars 3702 drive the first clamping plate 37 to clamp the glass slide 29 inside the second storage box 36, leaving only the bottom glass slide 29 unclamped. While the glass slide 29 is clamped, the second driving column 3805 is driven to move close to the second storage box 36 through the movement of the second dovetail slider 3204. The second driving column 3805 drives the two second square sliding bars 3802 to move away from each other through the second bevel and the second chamfer. Because the second square sliding bar 3802 and the second clamping plate 38 are fixedly connected, the two second square sliding bars 3802 drive the two second clamping plates 38 to move away from each other, so that the glass slides 29 carried on the upper surfaces of the two second clamping plates 38 fall into the right-angle positioning grooves of the two limiting columns 2804. This device is convenient for placing the glass slide 29 on the upper surface of the turntable 3. The movement sequence of the first clamping plate 37 first clamping and the second clamping plate 38 later releasing in this device is achieved by setting the relative spacing between the first bevel and the first chamfer to be smaller than the relative spacing between the second bevel and the second chamfer. During the movement, the first bevel will contact the first chamfer first, and then drive the two first clamping plates 37 to move closer to each other, and then the second bevel will contact the second chamfer, and then drive the two second clamping plates 38 to move away from each other. The movement of the first dovetail slider 3203 drives the mounting rod 2704 to move, and the mounting rod 2704 drives the rotating rod 2705 to move close to the first storage box 26, and the rotating rod 2705 drives the rubber head 2706 to abut against the outer surface of the cover glass. Because there is an inclined angle between the plane of the cover glass and the rotating rod 2705, when the mounting rod 2704 continues to move close to the first storage box 26, the rotating rod 2705 will rotate downward, so that the rubber head 2706 drives the cover glass to slide into the step groove 2602. At this time, the cover glass is The top of the glass slide leaves the right-angle stopper 2601. When the first dovetail slider 3203 moves in the opposite direction, the mounting rod 2704 moves away from the first storage box 26. The rubber head 2706 will first slowly reset under the force of the torsion spring 2708, and then leave the surface of the cover glass. Because the torsion spring 2708 has a small effect, it will not drive the cover glass to move up. At the same time, when the rotating rod 2705 resets and rotates upward, the piston 2702 is driven by the connecting rod 2703 to pressurize the inside of the liquid storage cylinder 27, so that the liquid storage cylinder 27 is The physiological saline solution is added to the glass slide 29 from the nozzle 2707. When the rotating rod 2705 is completely reset, the rubber head 2706 leaves the cover glass. Because the cover glass is tilted at the beginning, the cover glass will cover the pathogenic tissue block mixed liquid as the rubber head 2706 slowly leaves. Through this device, the cover glass can be tilted to cover the glass slide 29, avoiding bubbles between the cover glass and the glass slide 29, so that the subsequent electron microscope 23 can be It is to be observed more clearly; it should be noted that the nozzle 2707 has a small diameter and a large flow resistance, so when the rotating rod 2705 is stationary, the physiological saline inside will not flow out, and when the piston 2702 moves downward, air will be sucked from the nozzle 2707 to balance the pressure inside the liquid storage cylinder 27. When the pathogenic tissue block is detected by the device, there is no need to manually drip the pathogenic tissue block mixed liquid onto the slide 29, and then cover it with a cover glass and observe it under the electron microscope 23. When batch detection is performed, the detection efficiency is greatly improved; When the turntable 3 rotates, it drives the glass slide 29 to move to the bottom of the electron microscope 23, and the glass slide 29 is pressed down by the electric telescopic pressure head 25 to prevent it from moving around. This device facilitates the detection of the pathogenic tissue block mixed liquid on the upper surface of the glass slide 29.
