Description

Technical Field

[0001] This invention relates to the field of chicken embryo inoculation, and more particularly to a visual automated chicken embryo inoculation device. Background Technology

[0002] Culture of the allantoic cavity in chicken embryos is a traditional method for isolating influenza viruses. The inoculation site is usually located 2-3 mm above the boundary between the air cell and the tissue fluid in the egg. Before inoculation, the eggs need to be placed on an egg tray. Due to the difference in egg size, when the eggs are placed on the egg tray with the air cell facing upwards, the distance between the boundary between the air cell and the tissue fluid in different sized eggs and the bottom of the egg tray is not the same. Therefore, during inoculation, errors in the inoculation position of some eggs are likely to occur, causing tissue fluid to flow out from the inoculation site, resulting in the loss of nutrients in the chicken embryo and affecting its development.

By setting multiple air holes in the egg tray, the ventilation between the egg and the egg tray is improved, thereby reducing the concentration of microorganisms around the egg tray, reducing the chance of harmful microorganisms growing and multiplying on the egg surface, and reducing the risk of contamination. By using curved blocks to press and straighten the eggs that are tilted on the egg tray, each egg is placed upright during inoculation, thus ensuring the accuracy of the inoculation position and improving the accuracy of the experimental results.

[0024] Each egg tray 7 has several air holes 7001.

[0025] The working steps of this embodiment are as follows: Isolating influenza virus through allantoic cavity culture in chicken embryos is a traditional and classic method. The inoculation site is usually located 2-3 mm above the air cell tissue fluid boundary line of the egg. Before inoculation, it is usually necessary to screen the eggs for size, appearance, and chicken embryo quality to determine and mark the usability of the chicken embryos. Although the eggs are screened for size beforehand, it is difficult to ensure that each egg is the same size. Therefore, there are still errors in the size of some eggs. When larger and smaller eggs are placed side by side, the height of the air cell tissue fluid boundary line is different. Therefore, it is easy for some chicken embryos to be inoculated below the air cell tissue fluid boundary line, causing tissue fluid to flow out from the inoculation site, resulting in the loss of nutrients from the chicken embryo and affecting its development.

[0026] To avoid the above situation, firstly, the sieved eggs are placed sequentially on the egg tray 7 of the fixing ring 6 using an external feeding device until the placement box 5 is full of eggs. Then, the placement box 5 is transported to below the liquid storage box 3 by the conveyor belt 1. The conveyor belt 1 is turned off, and the control drive 102 moves the liquid storage box 3 and the inoculation needle 4 downward together. At the same time, the squeezing plate 8 moves downward along with the liquid storage box 3. As the squeezing plate 8 moves downward, the top of each egg will pass through the limiting hole 8001 on the upper squeezing plate 8. During the downward movement of the squeezing plate 8, the larger eggs will first contact the edge of the limiting hole 8001 and be squeezed by the squeezing plate 8. At the same time, since the fixing ring 6 and the placement box 5 are connected by a spring, the spring is compressed. The squeezed larger eggs will drive the fixing ring 6 and the egg tray 7 downward together until the sides of all eggs contact the edges of the adjacent limiting holes 8001, and then the downward movement stops. Figure 7 As shown, at this time, the height of each inoculation needle 4 is higher than or the same as the inoculation position height of the adjacent egg. Then, the electric slider 202 is controlled to drive the inoculation needle 4 to move to one side of the egg, piercing the inside of the egg to inoculate the chicken embryo. Thus, the larger eggs are squeezed by the squeezing plate 8, and the fixing ring 6 and egg tray 7 move the eggs downward during the compression of the spring. This ensures that the height of the air cell tissue fluid boundary line of each egg is lower than the height of the needle tip of the inoculation needle 4, thereby avoiding the problem that tissue fluid will flow out from the inoculation site after some larger eggs are inoculated, resulting in the loss of chicken embryo nutrients and affecting chicken embryo development. After inoculation is completed, the electric slider 202 is controlled to drive the inoculation needle 4 back to the initial position, so that the inoculation needle 4 is pulled out of the egg. Then, the drive unit 102 is controlled to drive the liquid storage box 3 and the inoculation needle 4 to move upward and return to the initial position. The conveyor belt 1 is started to transport the inoculated eggs to the next process. At the same time, the conveyor belt 1 transports the next batch of uninoculated eggs to the bottom of the liquid storage box 3 and repeats the above operation to complete the inoculation.

[0027] By setting multiple air holes 7001 on the egg tray 7, the ventilation effect between the egg and the egg tray 7 is improved, thereby reducing the concentration of microorganisms around the egg tray 7, reducing the chance of harmful microorganisms growing and multiplying on the egg surface, and reducing the risk of contamination.

[0028] Furthermore, considering that after inoculating an egg, the tip of the inoculation needle 4 may be contaminated with microorganisms or other substances from the egg's surface, in order to prevent cross-contamination between eggs and affect the accuracy of the experimental results, the inoculation needle 4 needs to be disinfected. After inoculation is complete and the inoculation needle 4 is withdrawn from the egg, using a left-to-right viewing reference, the motor 304 drives the infusion tube 302 and the inoculation needle 4 to rotate clockwise until the needle inside the disinfection box 303 presses against the sealing block 30301 below. The sealing block 30301 then opens outwards through the torsion spring force until the other needle of the inoculation needle 4 rotates out of the disinfection box 303. The sealing block 30301 then returns to its initial position through the torsion spring force. At this time, the used needle on the inoculation needle 4 squeezes the upper sealing block 30301, and the sealing block 30301 opens inward by the force of the torsion spring until the used needle is completely inside the sterilization box 303. The lower sealing block 30301 returns to its initial position by the force of the torsion spring until the inoculation needle 4 rotates 180 degrees. At this time, the two needles exchange positions. Then, the ultraviolet lamp 305 is turned on to sterilize the needle located in the placement box 5, while the other needle is used for inoculation. After the other needle is used, the above operation steps are repeated. This achieves the alternation of the two needles, prevents cross-contamination between eggs, improves the inoculation quality, and avoids affecting the accuracy of experimental results.

[0029] Example 2 Based on Example 1, such as Figure 1 , Figure 2 , Figure 6 and Figures 10-12 As shown, it also includes a fixing block 401, an elastic element 402, a connecting rod 403, and a curved block 404; two front-to-back symmetrical fixing blocks 401 are fixedly connected to each connecting plate 3001; an elastic element 402 is fixedly connected to each fixing block 401, and the elastic element 402 is a spring telescopic rod; a connecting rod 403 is fixedly connected to the telescopic ends of two adjacent elastic elements 402; four sets of front-to-back symmetrical adjustment structures are slidably connected to each connecting rod 403 through a connecting strip; each set of adjustment structures consists of ten front-to-back symmetrically distributed curved blocks 404; all curved blocks 404 are located below the extrusion plate 8; several sliding grooves 3002 are provided on each connecting plate 3001, and every two adjacent sliding grooves 3002 are in a figure-eight shape; each connecting strip slides within an adjacent sliding groove 3002.

[0030] Each curved block 404 is tilted on the side closest to the egg.

[0031] Each egg tray 7 is provided with a limit ring 7002, and each limit ring 7002 is rotatably connected to the adjacent fixed ring 6 by a torsion spring.

[0032] Each fixed ring 6 is provided with an inclined surface 6001.

[0033] Each limiting hole 8001 on the extrusion plate 8 is provided with an avoidance groove on the side near the inoculation needle 4.

[0034] It also includes a limiting block 501 and a squeezing rod 502; four limiting blocks 501 are slidably connected to the placement box 5; a mounting plate 5003 is slidably connected to the placement box 5, and the limiting blocks 501 are attached to the lower side of the mounting plate 5003; several squeezing rods 502 are fixed inside the placement box 5, and each squeezing rod 502 passes through the mounting plate 5003; each squeezing rod 502 is located directly below the adjacent egg tray 7.

[0035] The bottom of the placement box 5 is provided with two symmetrical front and rear limiting grooves 5004.

[0036] The working process of this embodiment is as follows: The egg tray 7 used to hold the eggs is usually larger than the eggs themselves. Therefore, when the feeding device places the eggs on the egg tray 7, the eggs usually tilt to one side, causing changes in the internal structure of the eggs. This makes it difficult for the inoculation needle 4 to accurately reach the predetermined inoculation site, affecting the accuracy of the inoculation position and making it impossible to observe the expected experimental phenomena, thus impacting the accuracy of the experimental results. To solve the above problem, during the inoculation process, when the liquid storage box 3 and the inoculation needle 4 move downwards, the fixing block 401, the elastic element 402, the connecting rod 403, and the curved block 404 will move downwards together until all the curved blocks... 404 is in contact with the placement plate 5002 below and continues to move downwards. At this time, all the curved blocks 404 are squeezed by the placement plate 5002, and the telescopic end of the elastic element 402 is gradually stretched upwards by the pulling of the curved blocks 404. At the same time, the connecting plate 3001 of the liquid storage box 3 continues to move downwards, and the connecting strip on the curved block 404 will slide upwards along the adjacent slide groove 3002. At the same time, the connecting strip on the curved block 404 will slide back and forth on the adjacent connecting rod 403. Since the two adjacent slide grooves 3002 are V-shaped, the connecting strip on the curved block 404 will drive the two adjacent curved blocks 404 to move closer to each other. Figure 10As shown, the eggs tilted on the egg tray 7 are simultaneously squeezed and straightened, ensuring that each egg is placed upright during inoculation, thus ensuring the accuracy of the inoculation position and improving the accuracy of the experimental results. By setting each curved block 404 to be tilted on the side closest to the egg, the curved block 404 first contacts the middle of the egg and fits more closely to the side wall of the egg, making it easier for the curved block 404 to straighten the tilted egg and preventing the curved block 404 from exerting hard pressure on the tilted egg, thus reducing the damage to the egg.

[0037] Furthermore, considering that some eggs have defects in their shells, such as uneven thickness or loose texture, the inoculation site may crack after inoculation. This would cause the internal tissue fluid to seep out through the cracks, contaminating the fixing ring 6 and the egg tray 7, increasing the need for subsequent manual cleaning. To mitigate this, the limiting ring 7002 of the egg tray 7 is initially placed at an angle, with the front of the limiting ring 7002 tilted upwards. Therefore, when the feeding device places the egg on the egg tray 7, the torsion spring force of the limiting ring 7002 will cause the limiting ring 7002 to tilt the egg backwards. During inoculation, the curved block 404 holds the egg in place. When the limiting ring 7002 is in a horizontal position due to the squeezing force of the egg, after inoculation, the egg loses the squeezing force of the curved block 404 and will be tilted backward again by the torsion spring force of the limiting ring 7002. At this time, the inoculation site of the egg will be placed upward. By placing the inoculation site upward, not only can the seepage rate of tissue fluid from the cracked position be slowed down, but for uncracked eggs, it can also prevent the inoculation site from contacting other parts of the device, avoid the inoculation site from being squeezed, and reduce the risk of external microorganisms being more easily invaded due to the breakage of the inoculation site. At the same time, the inclined surface 6001 avoids the middle position of the egg, thereby facilitating the adjustment of the egg and preventing pressure on the egg.

[0038] Meanwhile, when the inoculation needle 4 is pulled out of the egg, if tissue fluid seeps out through the inoculation site, the seeping tissue fluid is avoided by the clearance groove of the limiting hole 8001, thereby preventing the tissue fluid from sticking to the edge of the limiting hole 8001 of the extrusion plate 8, and further reducing the contamination on the device.

[0039] After the chicken embryo culture is completed, the device for holding the eggs usually needs to be cleaned and disinfected. Since the egg tray 7 is made of a flexible and elastic deformable material, it is easy to fold during the cleaning process, which will cause some dirt to be trapped and moisture to remain in the folded parts, affecting its drying efficiency. To solve the above problems, before cleaning, the limiting block 501 can be pulled outward until the limiting block 501 no longer squeezes and limits the mounting plate 5003. The mounting plate 5003 will drive the placement plate 5002, the fixing ring 6 and the egg tray 7 to slide down to the bottom of the placement box 5. At the same time, the squeezing rod 502 will pass through the mounting plate 5003 and squeeze the egg tray 7 above, making the inner side of the egg tray 7 bulge upward, which makes it easier for the inside of the egg tray 7 to be cleaned manually. At the same time, it avoids the egg tray 7 from folding during the cleaning process, effectively improving its cleaning effect and drying efficiency.

[0040] Considering that after inoculation in some laboratories, eggs need to be placed in incubators for heat preservation and cultivation, and some incubators are small in size and do not have internal partitions, the number of eggs that can be hatched at one time is small. To solve the above problem, this device only requires aligning the limiting groove 5004 of the placement box 5 with the upper side of the side plate 5001 of another placement box 5, so that the two placement boxes 5 are stacked together, thereby improving the space utilization of the incubator and improving the ease of use of the device.
