Description

Technical Field

[0001] The invention relates to the technical field of poultry blood sampling, in particular to a poultry inactivated vaccine adjuvant immunity testing system. Background Art

[0002] Inactivated vaccine adjuvants are a type of substance that can non-specifically change or enhance the body's specific immune response to antigens and play an auxiliary role. Adjuvants can induce the body to produce long-term, highly effective specific immune responses, improve the body's protective ability, while reducing the amount of immune substances used and reducing the production cost of vaccines. Inactivation refers to the use of physical or chemical methods to kill infectious viruses while maintaining the integrity of their antigen particles, causing them to lose their pathogenicity but retain their antigenicity.

[0003] With the development of the poultry farming industry, vaccines play an important role in preventing and controlling poultry diseases. However, monitoring and evaluating the immune effects of vaccines is a key step in ensuring the health of poultry. Currently, serological monitoring is one of the most commonly used methods to evaluate the immune effects of poultry vaccines. The immune level of animals is measured by blood sampling, and the antibody level is measured using serological methods to evaluate the immune effect of vaccines.

[0004] Currently, when conducting immunity testing on poultry, such as during the blood collection process of chickens, manual pressure is generally used to assist in fixing the chicken's body and wings. However, during the blood collection process, poultry tend to flap their wings, and the manual pressure method is not stable enough. In addition, multiple serum samples generally need to be collected, which makes the blood collection work more difficult for the staff, making it difficult to achieve stable and fast blood collection operations, and it is very easy to cause the needle to fall off, making it impossible to guarantee the quality of blood collection, which in turn affects the accuracy of the test results.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] For example 1, please refer to Figure 1-8 The present invention provides an inactivated vaccine adjuvant immunity test system for poultry, comprising a support platform 1, the top of which is symmetrically fixedly connected to a side panel 2, a pressure plate 3 being provided on a side wall adjacent to the two side panels 2, the interior of the pressure plate 3 being slidably connected to a slide column 4, and the bottom of the slide column 4 being fixedly connected to a main fixing plate 5, and the front and rear side walls of the main fixing plate 5 being hingedly connected to a secondary fixing plate 7;

[0033] The front and rear side walls of the pressing plate 3 are symmetrically provided with a quick fixing mechanism 6, so that when blood is collected from the poultry, the quick fixing mechanism 6 can be used to quickly squeeze and fix the body and wings of the poultry;

[0034] Furthermore, the quick fixing mechanism 6 includes a first spring 601, and the top of the first spring 601 is fixedly connected to the bottom of the pressure plate 3, and the bottom of the first spring 601 is fixedly connected to the top of the main fixing plate 5. The front and rear side walls of the pressure plate 3 are symmetrically fixedly connected to the connecting gear rod 602, and the two side walls of the auxiliary fixing plate 7 are fixedly connected to the rotating shaft 603. The ends of the two rotating shafts 603 that are away from each other are fixedly connected to the first gear 604, and a side wall of the first gear 604 is meshed with a side wall of the connecting gear rod 602.

[0035] More specifically, in this embodiment, when blood is collected from poultry, the poultry vaccinated with an inactivated vaccine adjuvant is first placed in the center of the support platform 1 in a supine position, with its belly aligned with the main fixing plate 5. Then, the pressing plate 3 is pressed down, and the top of the first spring 601 is fixedly connected to the bottom of the pressing plate 3, and the bottom of the first spring 601 is fixedly connected to the top of the main fixing plate 5, so that the first spring 601 can be used to normally push the main fixing plate 5 down until the lower recessed position of the main fixing plate 5 fits the belly of the poultry.

[0036] Then continue to press the pressing plate 3 downward. At this time, since the main fixing plate 5 fits against the poultry's belly, the first spring 601 will be squeezed, and the elastic force of the first spring 601 will drive the main fixing plate 5 to fix the poultry's body. At this time, the pressing plate 3 will continue to descend relative to the main fixing plate 5, compressing the elastic stroke of the first spring 601. At this time, the connecting gear rod 602 is symmetrically fixedly connected through the front and rear side walls of the pressing plate 3, and the two side walls of the auxiliary fixing plate 7 are fixedly connected to the rotating shaft 603, and the ends of the two rotating shafts 603 that are away from each other are fixedly connected to the first gear 604. At the same time, a side wall of the first gear 604 is meshed with a side wall of the connecting gear rod 602, so that the descending connecting gear rod 602 can drive the first gear 604 to rotate, so that the two auxiliary fixing plates 7 are gradually deflected downward from a direction parallel to the ground until the wings on both sides of the poultry are squeezed.

[0037] Then, during the descending process of the pressure plate 3, a slide bar 605 is fixedly connected to the two side walls of the pressure plate 3, and a first slide groove 12 is penetrated through the side wall of the side plate 2 corresponding to the slide bar 605, and the outer wall of the slide bar 605 slides in contact with the inner wall of the first slide groove 12, thereby utilizing the slide bar 605 and the first slide groove 12 to ensure the stability of the pressure plate 3 and the main fixed plate 5 when moving downward, and then a tooth plate 606 is fixedly connected to one side wall of the slide bar 605, and a second gear 607 is meshed with one side wall of the tooth plate 606, and a ratchet 608 is fixedly connected to the side where the two second gears 607 are close to each other, The toothed plate 606 can be used to drive the ratchet 608 to rotate during the downward movement, and then a push rod 610 is connected to the fixed block 609 through internal sliding, and the push rod 610 forms a telescopic structure by connecting the pressure rod 611 and the second spring 612, and the top of the push rod 610 is pressed against the tooth groove of the ratchet 608, so that the ratchet 608 can be driven to rotate during the downward movement of the pressure plate 3. When the pressure is pressed to the appropriate position, the downward pressure is stopped, and the second spring 612 can be used to drive the push rod 610 to lock the ratchet 608, thereby achieving the effect of quickly fixing the poultry.

[0038] As described above, when blood is collected from poultry, the main fixing plate 5 can be driven to fit and fix the poultry's body by pressing the pressing plate 3, and the two auxiliary fixing plates 7 can be driven to automatically squeeze and fix the poultry's wings during the continuous downward pressure, thereby achieving the effect of quickly fixing the poultry. There is no need for multiple auxiliary fixations by manpower, so that the staff can maintain a stable blood collection efficiency during multiple blood collection measurements.

[0039] In the second embodiment, based on the above embodiment, an observation slot 8 is provided on the top of the auxiliary fixing plate 7, a support cylinder 9 is provided inside the observation slot 8, and a stable extraction mechanism 10 is provided on the inner wall of the observation slot 8 corresponding to the support cylinder 9, so that when blood is collected from poultry, the support cylinder 9 can be used to achieve stable blood sampling of the poultry;

[0040] Furthermore, the stable extraction mechanism 10 includes a support frame 1001, and the inner wall of the observation slot 8 is provided with a second sliding groove 13 corresponding to the support frame 1001, and the outer wall of the support frame 1001 slides in contact with the inner wall of the second sliding groove 13, the outer wall of the support tube 9 is threadedly connected to a connecting ring 1002, and the outer wall of the connecting ring 1002 is symmetrically fixedly connected to a shaft 1003, the outer wall of the shaft 1003 is rotatably connected to the inside of the support frame 1001, and the outer wall of the shaft 1003 rotates with the support frame 1001 in a damped manner;

[0041] More specifically, in this embodiment, an observation slot 8 is provided through the top of the auxiliary fixing plate 7, so that after the wings of the poultry are squeezed and fixed by using the two auxiliary fixing plates 7, the blood collection position at the root of the poultry wings can be observed through the observation slot 8, and then a support tube 9 is provided inside the observation slot 8, and the outer wall of the support tube 9 is threadedly connected to the connecting ring 1002, and the outer wall of the connecting ring 1002 is symmetrically fixedly connected to the shaft rod 1003, and at the same time, the outer wall of the shaft rod 1003 is rotatably connected to the inside of the support frame 1001, and the outer wall of the shaft rod 1003 rotates with the support frame 1001 in a damped manner, and the internal thread of the support frame 1001 is connected to the rotating rod 1004, so that when the auxiliary fixing plate 7 is passed through After the support tube 9 is turned over and directed toward the approximate position of the wing root, the rotary handle 1005 can be rotated to drive the rotary rod 1004 to rotate, and the second slide groove 13 can be used to limit the support frame 1001, so that the support tube 9 can be adjusted to the left and right directions by rotating the rotary handle 1005, and the shaft rod 1003 and the support frame 1001 can be coordinated with the damping rotation to adjust the up and down direction of the support tube 9. When the adjustment is completed, the support tube 9 is rotated, and the thread drives one end of the support tube 9 to follow up and move toward the blood sampling position at the root of the poultry wing until it fits with the blood sampling site. At this time, the blood collection syringe can be inserted into the support tube 9, completing the stable clamping of the insertion direction and subsequent blood collection to avoid shaking.

[0042] As described above, when blood is collected from poultry, the flipping and squeezing of the auxiliary fixing plate 7 can be used to drive the support tube 9 toward the approximate position of the wing root, and the coordination between the shaft 1003, the rotating rod 1004 and the connecting ring 1002 can be used to accurately adjust and fix the direction of the support tube 9, so as to facilitate fixing the syringe during the blood drawing process, maintain stable blood sampling, avoid shaking, reduce the difficulty of blood drawing work for staff, ensure the quality of multiple blood drawing, and thus ensure the accuracy of subsequent test results.

[0043] In the third embodiment, based on the above embodiment, a feather smoothing mechanism 11 is provided on the inner wall of the support tube 9 so that when blood is collected from poultry, the feathers at the blood collection position are pushed away and separated by the feather smoothing mechanism 11.

[0044] Furthermore, the feather smoothing mechanism 11 includes a slider 1101. A third sliding groove 14 is formed on the inner wall of the support tube 9 at equal distances corresponding to the slider 1101, and the four ends of the slider 1101 slide in contact with the inner wall of the third sliding groove 14. One end of the support tube 9 is fixedly connected to a connecting block 1102 at equal distances, and a smoothing plate 1103 is hingedly connected to the other side wall of the connecting block 1102. The four smoothing plates 1103 are fixedly connected to a side wall facing the slider 1101 with a third spring 1104, and the other end of the third spring 1104 is fixedly connected to the side wall of the slider 1101 facing the smoothing plate 1103.

[0045] More specifically, in this embodiment, when blood is collected from poultry, a connecting block 1102 is fixedly connected at an equal distance through one end of the support cylinder 9, and a caressing plate 1103 is hingedly connected to the other side wall of the connecting block 1102, and a third spring 1104 is fixedly connected to one side wall of the four caressing plates 1103 facing the slider 1101, and the other end of the third spring 1104 is fixedly connected to the side wall of the slider 1101 facing the caressing plate 1103, and the slider 1101 faces the caressing plate 1103. A fourth spring 1105 is fixedly connected to one side wall of the support tube 3. When the syringe is not inserted, the fourth spring 1105 will limit the position of the slider 1101, so that the slider 1101 is at the farthest position from the caressing plate 1103. The four third springs 1104 can be used to pull the caressing plate 1103, so that the four caressing plates 1103 fit together to form a cone, which facilitates the follow-up movement of one end of the support tube 9 toward the blood collection position at the root of the poultry wing until it fits the blood collection site.

[0046] Then, when the syringe is inserted, the outer wall of the syringe first slides against the inner wall of the support tube 9, and the needle tip passes through the through hole 1106. When the syringe pushes the slider 1101, the slider 1101 first moves toward the caressing plate 1103, thereby squeezing the third spring 1104, causing the four caressing plates 1103 to expand. The caressing plates 1103 can then be used to push and separate the feathers at the blood collection position, preventing the feathers from blocking the blood collection position during the blood collection process.

[0047] Then, in order to avoid the need to overcome the elastic force of the fourth spring 1105 during the blood collection process, a limiting hole 15 is opened at equal distances through the inner wall of the support tube 9, and the inner wall of the limiting hole 15 is slidably connected with a fixing rod 1107, and the outer wall of the fixing rod 1107 is fixedly connected with a supporting ring 1109, and at the same time, the outer wall of the fixing rod 1107 is fitted with a fifth spring 1108, and one end of the fifth spring 1108 is fixedly connected to the inner wall of the support tube 9, and the other end of the fifth spring 1108 is fixedly connected to one end face of the supporting ring 1109, When the slider 1101 is moved to its maximum position, the outer wall of the slider 1101 is provided with a fixing hole 1110 corresponding to the fixing rod 1107, and the adjacent ends of the four fixing rods 1107 are truncated into a cone shape. When the slider 1101 is moved to its maximum position, the outer wall of the slider 1101 contacts the inclined ends of the fixing rods 1107, and the four fixing rods 1107 are moved away from each other until the ends of the four fixing rods 1107 are aligned with the fixing holes 1110 and are inserted into the fixing holes 1110 under the drive of the fifth spring 1108, thereby completing the locking of the slider 1101 and facilitating blood collection.

[0048] When blood collection is completed, the syringe can be pulled out of the support tube 9 and the collected serum sample can be sent to the sampling tube. At this time, the antibody level of the serum sample can be measured to evaluate the immune effect of the vaccine. Then the support tube 9 is rotated in the opposite direction to move it away from the blood collection position, and then the rotating ring 1112 is rotated. The first guide block 1114 is fixedly connected to the end away from the four fixed rods 1107, and the outer wall of the rotating ring 1112 is fixedly connected to the second guide block 1115 corresponding to the first guide block 1114, and the second guide block 1115 is inclined toward the side wall of the first guide block 1114. At the same time, the outer wall of the end of the limit block 1111 is fitted and slid with the inner wall of the limit groove 1116, and the outer wall of the fixed rod 1107 is fitted and slid with the inner wall of the through groove 1113, so that it can be rotated by the rotating ring 1112. The second guide block 1115 is moved toward the first guide block 1114. Under the action of the inclined surface, the four fixing rods 1107 are simultaneously pulled out of the fixing holes 1110. At this time, the four caressing plates 1103 are automatically merged and reset under the drive of the fourth spring 1105. Then, the two connecting pressure rods 611 are simultaneously pushed downward to release the lock of the ratchet 608. At this time, the top of the sliding rod 605 is fixedly connected with the tension spring 613, and the top of the tension spring 613 is fixedly connected with the support block 614, so that the tension spring 613 can be used to pull the sliding rod 605 back to its original position, and the first spring 601 is used to push the main fixing plate 5, so that the two auxiliary fixing plates 7 are returned to a state parallel to the ground, quickly completing the recovery of the device, further shortening the time consumed in multiple blood sampling measurements, and improving blood sampling efficiency.

[0049] Furthermore, some of the stroking plates 1103 may be opposite to the wings of the poultry, and may not be able to unfold or may unfold at a small angle. This does not affect the effect of restricting the feathers at the blood collection position, and can also achieve the effect of preventing the feathers from fluttering randomly and affecting the judgment of the staff.

[0050] As described above, when blood is collected from poultry, the slider 1101 can be used to drive the four smoothing plates 1103 to unfold during the syringe insertion process, so that the smoothing plates 1103 can be used to push and separate the feathers at the blood collection position, thereby avoiding the feathers blocking the blood collection position during the blood collection process and affecting the judgment of the staff, ensuring a better blood collection environment, and helping to improve the stability during blood collection.

[0051] Working principle: When blood is collected from poultry, the poultry vaccinated with inactivated vaccine adjuvant is first placed in the center of the support platform 1 in a supine position, with the belly aligned with the main fixing plate 5, and then the pressing plate 3 is pressed down until the lower concave position of the main fixing plate 5 fits the belly of the poultry;

[0052] Then, the pressing plate 3 is pressed downward. At this time, the main fixing plate 5 is in contact with the poultry's belly, thereby squeezing the first spring 601. The elastic force of the first spring 601 drives the main fixing plate 5 to fix the poultry's body. At this time, the pressing plate 3 continues to descend relative to the main fixing plate 5, compressing the elastic stroke of the first spring 601, so that the descending connecting gear rod 602 drives the first gear 604 to rotate, causing the two auxiliary fixing plates 7 to gradually deflect downward from the direction parallel to the ground until the wings on both sides of the poultry are squeezed.

[0053] Then, during the descending process of the pressing plate 3, the tooth plate 606 is used to drive the ratchet 608 to rotate during the downward movement. When the pressing plate 3 is pressed down to a suitable position, the downward pressure is stopped, and the second spring 612 can be used to drive the lever 610 to lock the ratchet 608, thereby achieving the effect of quickly fixing the poultry.

[0054] Then, after the supporting tube 9 is turned toward the approximate position of the wing root by flipping the auxiliary fixing plate 7, the blood sampling position of the wing root of the poultry can be observed through the observation slot 8, and then the supporting tube 9 is driven to adjust the left and right directions by rotating the rotary handle 1005, and the damping rotation of the shaft 1003 and the support frame 1001 is coordinated to adjust the up and down direction of the supporting tube 9. When the adjustment is completed, the supporting tube 9 is rotated, and the thread drives one end of the supporting tube 9 to follow up and move toward the blood sampling position of the wing root of the poultry until it fits the blood sampling site. At this time, the blood collection needle can be inserted into the supporting tube 9;

[0055] Then, when the syringe is inserted, the needle tip passes through the through hole 1106. When the syringe pushes the slider 1101, the slider 1101 first moves toward the caressing plate 1103, thereby squeezing the third spring 1104, causing the four caressing plates 1103 to expand. Then, the caressing plates 1103 can be used to push and separate the feathers at the blood collection position.

[0056] Then, to avoid the need to overcome the elastic force of the fourth spring 1105 during the blood collection process, when the slider 1101 moves to the maximum position, the outer wall of the slider 1101 will contact the inclined end of the fixing rod 1107, and the four fixing rods 1107 will move away from each other until the ends of the four fixing rods 1107 are aligned with the fixing holes 1110. Driven by the fifth spring 1108, the four fixing rods 1107 are inserted into the fixing holes 1110, completing the locking of the slider 1101 and facilitating blood collection.

[0057] When the blood collection is completed, the syringe can be pulled out from the support cylinder 9 and the collected serum sample can be sent to the sampling tube. At this time, the antibody level of the serum sample can be measured to evaluate the immune effect of the vaccine.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
