Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an avian influenza antibody multi-titer quantitative detection kit. Background Technique

[0002] Titer is a term expressing concentration and is usually used in chemistry, pathology and immunology. Titer is the reciprocal of dilution. Virus titer refers to the concentration of a virus suspension, also known as the titer of the virus, the number of plaque-forming units or the number of infection centers;

[0003] Chinese Patent with publication number CN214895324U discloses an avian influenza antibody multi-titer quantitative detection kit, which relates to the technical field of medical auxiliary equipment. The avian influenza antibody multi-titer quantitative detection kit includes a base and a connecting plate. The connecting plate is fixedly arranged on the top of the base. Quantitative mechanisms are arranged on the top of the base and one side of the connecting plate. The quantitative mechanism includes a reinforcing plate. The reinforcing plate is fixedly arranged on the top of the base, and a placing plate is arranged at the bottom of the reinforcing plate. The avian influenza antibody multi-titer quantitative detection kit has a simple overall design and a compact structure through the setting of the quantitative mechanism. The quantitative detection is completed by the way that the top force when the top sheet rotates and displaces one circle pushes the vessel to displace, which is convenient for the staff to use, can effectively ensure the dropped amount received by the vessel, and can effectively reduce the detection error;

[0004] The above-mentioned prior art solutions have the following defects: Rotating the rotating shaft drives the vessels on the titer plate to move under the burette for quantitative titration. After a group of vessels complete the quantitative titration, the user needs to manually push the titer plate to move so that another group of vessels on the titer plate can move under the burette for titration, thereby reducing the convenience of using the device. Based on the existing avian influenza antibody multi-titer quantitative detection kit, technological innovation is carried out. Content of the Utility Model

[0005] The purpose of the utility model is to provide an avian influenza antibody multi-titer quantitative detection kit to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An avian influenza antibody multi-titer quantitative detection kit, including:

[0007] A support frame, two groups of "type limit plates are evenly arranged on the top of the support frame. A set of installation holes are opened on the opposite sides of the two groups of "type limit plates. Springs are arranged in the installation holes. A set of round head pins are arranged on the opposite sides of the two groups of springs. A titer plate is placed on the right side of the top of the support frame. Vessels are placed in the placement grooves of the titer plate. Jacks are evenly opened on the front and back sides of the titer plate.

[0008] Preferably, a supporting block is provided at the rear side of the support frame. A groove is formed at the top of the supporting block, and a burette is placed in the groove. The liquid dropping port of the burette is aligned with the round head pin.

[0009] Preferably, a sliding groove is formed at the top of the support frame. A lead screw is arranged in the sliding groove. An internally threaded slider is screwed on the outer side wall of the lead screw. A push plate is arranged at the top of the internally threaded slider, and the push plate is located on the right side of the titer plate.

[0010] Preferably, the right side of the lead screw penetrates through the right side of the support frame and is connected with a worm gear. A worm is meshed with the top of the worm gear. A hand wheel is arranged at the front side of the worm.

[0011] Preferably, two groups of rotating shaft seats are uniformly arranged on the outer side wall of the worm. The two groups of rotating shaft seats are uniformly arranged on the right side of the support frame.

[0012] Preferably, the jack is aligned with the utensil, and the round head part of the round head pin corresponds to the jack.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, when the hand wheel is rotated, the titer plate is pushed to move leftward by the push plate. Since the spring drives the round head pin to insert into the jack, a sense of jerk will be generated during the movement of the titer plate. Therefore, whenever a sense of jerk is generated during the movement of the titer plate, it means that the utensil has moved below the liquid dropping port of the burette, thereby assisting the user to accurately move the utensil below the liquid dropping port of the burette, and further ensuring the accuracy of multi-titer quantification.

[0015] The titer plate can be limited by the "type limiting plate, and the spring drives the round head pin to insert into the jack, which can ensure the stability of the utensil on the titer plate during multi-titer quantification, thereby ensuring the reliability of the device in use.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3, an avian influenza antibody multi-titer quantitative detection kit, comprising a support frame 1. Two groups of "L"-shaped limit plates 11 are evenly and fixedly arranged on the top of the support frame 1. A set of mounting holes are opened on the opposite sides of the two groups of "L"-shaped limit plates 11. Springs 18 are fixedly arranged in the mounting holes. A set of round-headed pins 19 are fixedly arranged on the opposite sides of the two springs 18. A titer plate 2 is placed on the right side of the top of the support frame 1. A container 21 is placed in the placement groove of the titer plate 2. A set of jacks 22 are evenly opened on the front and back sides of the titer plate 2. The jacks 22 are aligned with the container 21. The round-headed part of the round-headed pin 19 corresponds to the jack 22. A support block 3 is fixedly arranged on the rear side of the support frame 1. A groove is opened on the top of the support block 3. A burette 31 is placed in the groove. The liquid dropping port of the burette 31 is aligned with the round-headed pin 19. When the titer plate 2 drives the container 21 to move between the two groups of "L"-shaped limit plates 11 and aligns the jack 22 with the round-headed pin 19, the spring 18 drives the round-headed part of the round-headed pin 19 to insert into the jack 22 by its own elastic force. At this time, the container 21 aligned with the jack 22 is located below the liquid dropping port of the burette 31. The avian influenza antibody multi-titer quantitative work is carried out on the container 21 through the burette 31. Since the spring 18 drives the round-headed pin 19 to insert into the jack 22, a sense of jerk will be generated during the movement of the titer plate 2. And because the round-headed pin 19, the jack 22, the container 21 and the burette 31 correspond to each other, every time a sense of jerk is generated during the movement of the titer plate 2, it means that the container 21 has moved below the liquid dropping port of the burette 31. This helps the user to accurately move the container 21 below the liquid dropping port of the burette 31, thereby ensuring the accuracy of multi-titer quantification. A chute is opened on the top of the support frame 1. A lead screw 12 is rotatably arranged in the chute. An internally threaded slider 16 is screwed on the outer side wall of the lead screw 12. A push plate 17 is fixedly arranged on the top of the internally threaded slider 16. The push plate 17 is located on the right side of the titer plate 2. The right side of the lead screw 12 penetrates through the right side of the support frame 1 and is connected with a worm gear 13. A worm 14 is meshed with the top of the worm gear 13. A handwheel 15 is fixedly arranged on the front side of the worm 14. Rotating the handwheel 15 drives the worm gear 13 to rotate through the worm 14. The worm gear 13 drives the internally threaded slider 16 to move through the lead screw 12. The internally threaded slider 16 pushes the titer plate 2 to move leftward through the push plate 17. Two rotating shaft seats 141 are evenly and rotatably arranged on the outer side wall of the worm 14. The two rotating shaft seats 141 are evenly and fixedly arranged on the right side of the support frame 1.

[0022] Working principle: Rotating the handwheel 15 drives the worm wheel 13 to rotate through the worm 14. The worm wheel 13 drives the internally threaded slider 16 to move through the lead screw 12. The internally threaded slider 16 pushes the titer plate 2 to move leftward through the push plate 17. When the titer plate 2 drives the vessel 21 to move between the two "L"-shaped limit plates 11 and aligns the jack 22 with the round head pin 19, the spring 18 drives the round head part of the round head pin 19 to insert into the jack 22 by its own elastic force. At this time, the vessel 21 aligned with the jack 22 is located below the liquid dropping port of the titrator 31. The avian influenza antibody multi-titer quantification work is carried out on the vessel 21 through the titrator 31. Since the spring 18 drives the round head pin 19 to insert into the jack 22, a sense of jerk will be generated in the movement of the titer plate 2. And because the round head pin 19, the jack 22, the vessel 21 and the titrator 31 correspond to each other, every time a sense of jerk is generated in the movement of the titer plate 2, it means that the vessel 21 has moved below the liquid dropping port of the titrator 31. This helps the user to accurately move the vessel 21 below the liquid dropping port of the titrator 31, thereby ensuring the accuracy of the multi-titer quantification.
