Description

Technical Field

[0001] The present invention relates to the technical field of vaccine detection, and more specifically, to a fully automatic online fluid sample loading and collecting integrated device. Background Art

[0002] In the medical industry, scientific experiments and industrial production processes, such as vaccine production, it is necessary to conduct quality inspections on the vaccines produced to confirm that their safety, effectiveness and purity comply with relevant national regulations and standards.

[0003] During the continuous production process of vaccines, the concentration of the vaccine needs to be tested to ensure the effectiveness of active ingredients (such as antigens). If the concentration is too low, the vaccine may not stimulate sufficient immune response, resulting in the vaccine recipient not getting the protection he or she deserves. If the concentration is too high, there will be a risk of side effects, such as allergic reactions.

[0004] Vaccine concentration is usually tested using a refractometer. The principle is that when light passes through liquids of different concentrations, different refraction angles will be generated. The concentration of the liquid is determined by measuring these refraction angles. In the past, manual refractometers were used for testing. Later, in order to adapt to the rhythm of production testing, automatic refractometers appeared. Automatic refractometers are mainly composed of prisms, covers, calibration bolts, optical system pipelines and other components. Compared with manual refractometers, automatic refractometers only need to drop the sample on the prism and then cover it with a cover to automatically detect. It has the characteristics of fast speed and high accuracy.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0030] Refer to the instruction manual Figure 1-Figure 10A fully automatic online fluid sample loading and collecting integrated device comprises a machine platform 1, a refractometer 2 is installed on the machine platform 1, and a prism 21 is provided on the upper surface of the refractometer 2; a guide frame 3 is fixedly installed on the upper surface of the machine platform 1, a dropper 4 is installed on the front side of the guide frame 3, a liquid inlet 401 and a liquid outlet 402 are respectively arranged on both sides of the dropper 4, a dropper nozzle 40 is arranged at the bottom of the dropper 4, the fluid flows into the dropper 4 from the liquid inlet 401 and is discharged from the liquid outlet 402, and the dropper 4 also drops the fluid from the dropper nozzle 40 onto the prism 21, a vertical groove 31 is opened at the upper end of the guide frame 3, and the vertical groove 31 is provided with a vertical groove 31. The bottom is provided with an inclined groove 32, and a driving assembly 6 is fixedly installed on the upper surface of the machine 1, and the driving assembly 6 is used to drive the dropper 4 to move along the vertical groove 31 and the inclined groove 32; a cleaning assembly 5 is fixedly installed on one side of the bottom of the dropper 4; the driving assembly 6 includes a slide plate 64, and when the slide plate 64 is rotated from a horizontal state to a vertical state, it is used to drive the dropper 4 to move downward along the vertical groove 31, so that the dropper nozzle 40 is close to the prism 21, and when the slide plate 64 moves downward in the vertical state, it is used to drive the dropper 4 to move obliquely downward along the inclined groove 32, so that the cleaning assembly 5 cleans the surface of the refractometer 2.

[0031] Furthermore, a reversing valve is installed inside the dripping tube 4 , and the reversing valve is used to connect the liquid inlet 401 with the liquid outlet 402 or connect the liquid inlet 401 with the dripping nozzle 40 .

[0032] It should be noted that the reversing valve adopts a two-position three-way voltage magnetic reversing valve. When detection is not required, the liquid inlet 401 is connected to the liquid outlet 402 to realize the delivery of the vaccine concentrate. When detection is required, the liquid inlet 401 is connected to the drip nozzle 40 to drop the vaccine concentrate sample onto the prism 21. The delivery pump for delivering the vaccine concentrate is a peristaltic pump.

[0033] In the above technical solution, before the test, the slide 64 is rotated from the horizontal to the vertical state, so that the dropper 4 is close to the prism 21, and then the fluid is dripped from the dropper nozzle 40 to the prism 21 through the dropper 4 to achieve the purpose of fluid sampling, and then the refractometer 2 is used for detection. After the detection is completed, the slide 64 is moved downward in the vertical state, and the dropper 4 and the cleaning component 5 can be driven to move obliquely downward at the same time. The cleaning component 5 contacts the surface of the prism 21 to remove the fluid and achieve the purpose of fluid sampling. In this embodiment, the fluid is a vaccine stock solution.

[0034] In this embodiment, if Figure 1-Figure 7As shown, the driving assembly 6 includes a mounting frame 61, on which a turntable 62 and a power component 66 for driving the turntable 62 to rotate are mounted, a slide plate 64 is slidably mounted on the front side of the turntable 62, a movable frame 65 is mounted on the front side of the slide plate 64, a support rod 11 is fixedly mounted on the upper surface of the machine 1, the movable frame 65 is vertically slidably mounted on the support rod 11, a connecting rod 2 42 is laterally fixedly mounted on the upper end of the movable frame 65, and the connecting rod 2 42 is laterally movably inserted into the drip tube 4.

[0035] Furthermore, a slide groove 651 is transversely arranged on one side of the movable frame 65 close to the slide plate 64 , and a slide shaft 1 641 is fixedly connected to one side of the slide plate 64 close to the movable frame 65 , and the slide shaft 1 641 slides inside the slide groove 651 .

[0036] Furthermore, a driving wheel 63 is installed between the turntable 62 and the skateboard 64, and a rotating driving member 60 is installed on the rear side of the mounting frame 61. The rotating driving member 60 is used to drive the driving wheel 63 to rotate. An eccentric groove 631 is provided on the surface of the driving wheel 63 close to the skateboard 64. A sliding shaft 642 is fixedly connected to the side of the skateboard 64 close to the driving wheel 63, and the sliding shaft 642 slides inside the eccentric groove 631.

[0037] It should be noted that if Figure 5-Figure 7 As shown, the slide plate 64 is in a horizontal state. At this time, the power component 66 drives the turntable 62 to rotate 90° counterclockwise, so that the turntable 62 drives the slide plate 64 to rotate from the horizontal state to the vertical state. Since the slide shaft 1 641 is located inside the slide groove 651, the slide plate 64 can drive the moving frame 65 to move downward through the slide shaft 1 641, and the moving frame 65 drives the drip tube 4 to move downward through the connecting rod 2 42. A connecting rod 1 41 is installed on one side of the cleaning component 5, and one end of the connecting rod 1 41 is inserted into the vertical groove 31 and can slide along the vertical groove 31 and the inclined groove 1 32. Similarly, when the power component 66 drives the turntable 62 to rotate from the vertical state to the horizontal state, the moving frame 65 will drive the drip tube 4 to move upward.

[0038] It should also be noted that when the rotating driving member 60 drives the driving wheel 63 to rotate, since the sliding shaft 642 is inserted into the eccentric groove 631, the driving wheel 63 can drive the slide plate 64 to move back and forth. When the slide plate 64 is in a vertical state, if the driving wheel 63 rotates, it can also drive the slide plate 64 to move vertically for a distance, so that the dropper 4 can move obliquely downward in the inclined groove 32, wherein the rotating driving member 60 is a stepping motor.

[0039] In the above technical solution, if Figure 6 and Figure 7As shown, guide grooves 622 are provided on both sides of the turntable 62 , and both ends of the slide plate 64 slide inside the two guide grooves 622 respectively. The height of the guide grooves 622 is lower than the rear surface of the moving frame 65 .

[0040] It should be noted that, since the movable frame 65 can only move vertically and the turntable 62 can rotate, the height of the guide groove 622 is lower than the rear surface of the movable frame 65. The purpose is to prevent the guide groove 622 from colliding with the movable frame 65 during the rotation of the turntable 62.

[0041] In the above technical solution, the power component 66 includes a second rotating driving component 661 and a gear 662. The second rotating driving component 661 is fixedly mounted on the mounting frame 61. The output end of the second rotating driving component 661 is connected to the gear 662. The turntable 62 has gear teeth 621 in the circumferential direction, and the gear 662 is meshed with the gear teeth 621.

[0042] It should be noted that if Figure 5 As shown, the second rotary drive member 661 drives the gear 662 to rotate, and the gear 662 drives the turntable 62 to rotate by meshing with the gear teeth 621. The second rotary drive member 661 is a stepping motor.

[0043] In this embodiment, if Figure 4 As shown, the cleaning component 5 includes a fixed frame 50, which is fixedly installed on one side of the drip tube 4, and a cleaning cotton 51 is fixedly installed inside the fixed frame 50 close to the drip tube 4. The end of the cleaning cotton 51 is located on the side of the drip nozzle 40 close to the fixed frame 50, and the cleaning cotton 51 is located on the lower side of the drip nozzle 40. The side of the fixed frame 50 away from the cleaning cotton 51 has a discharge port 52, and the discharge port 52 is connected to the collecting cylinder.

[0044] In this embodiment, the implementation is as follows: before the test, the reversing valve connects the liquid inlet 401 with the liquid outlet 402 to deliver the vaccine to the liquid collection tank. Figure 2 , Figure 5 and Figure 6 In the state, the slide plate 64 is located at the far right. When detection is required:

[0045] (1) First, the power component 66 drives the turntable 62 to rotate 90° counterclockwise, and the turntable 62 drives the slide plate 64 to rotate. The slide plate 64 drives the movable frame 65 to move downward through the sliding shaft 1 641, and the movable frame 65 drives the dropper 4 to move downward through the connecting rod 2 42. At this time, the connecting rod 1 41 slides from top to bottom inside the vertical groove 31. This process makes the dropper nozzle 40 close to the prism 21.

[0046] (2) Then, the liquid inlet 401 is connected to the drip nozzle 40 through the reversing valve, and the vaccine stock solution sample is dripped onto the prism 21 from the drip nozzle 40.

[0047] (3) Next, the power component 66 drives the turntable 62 to rotate 90° clockwise, so that the drip tube 4, the movable frame 65 and the slide plate 64 are reset.

[0048] (4) Next, the prism 21 is covered with a cover 9 and the concentration of the active ingredient in the vaccine stock solution sample is tested using the refractometer 2 .

[0049] (5) Then, after the test is completed, remove the pressure cover 9 and repeat the above process (1) to move the dropper 4 downward. At this time, the slide 64 is in the uppermost position. The driving wheel 63 is driven to rotate by the rotating driving member 60, and the sliding shaft 2 642 is driven through the eccentric groove 631, so that the slide 64 moves downward. At this time, the connecting rod 1 41 enters the inclined groove 1 32 from the bottom of the vertical groove 31 and moves obliquely downward. During this process, the cleaning cotton 51 contacts and rubs against the upper surface of the prism 21 for a distance, absorbing the vaccine concentrate sample on the surface of the prism 21. The rotating driving member 60 can drive the driving wheel 63 to rotate three or four circles, so that the cleaning cotton 51 wipes the surface of the prism 21 multiple times.

[0050] (6) Finally, repeat the above step (3). Note that before repeating the above step (3), make sure that the slide plate 64 is located at the uppermost position.

[0051] During the detection, the above technical scheme causes the slide plate 64 to rotate from a horizontal state to a vertical state, so that the drip nozzle 40 can be close to the prism 21, which is convenient for loading the vaccine concentrate sample. After the detection is completed, the slide plate 64 is moved downward in a vertical state, so that the cleaning cotton 51 can contact and rub against the upper surface of the prism 21, thereby achieving the purpose of absorbing the vaccine concentrate sample on the surface of the prism 21. It has a high degree of automation and does not require manual loading and collecting of samples.

[0052] Refer to the instruction manual Figure 1-Figure 4 An extrusion assembly 7 is installed on the vertical groove 31, and the extrusion assembly 7 includes a fixed shaft 71, which is laterally fixedly installed on the guide frame 3, and a movable plate 72 is laterally slidably installed on the fixed shaft 71. An elastic component 73 is sleeved on the fixed shaft 71, and the elastic component 73 is used to reset the movable plate 72 in the direction of the guide frame 3. A pressure plate 74 is fixedly connected to one side of the movable plate 72 close to the front end of the cleaning cotton 51, and the other end of the movable plate 72 extends to one end of the slide plate 64.

[0053] It should be noted that after the above (6), the driving wheel 63 can be driven to rotate by rotating the driving member 60, and the sliding plate 64 can be driven to move back and forth horizontally by the driving wheel 63. One end of the sliding plate 64 pushes the end of the movable plate 72, so that the elastic component 73 is compressed, and the movable plate 72 drives the pressing plate 74 to squeeze the cleaning cotton 51 into the interior of the fixed frame 50, and squeeze out part of the vaccine stock solution in the cleaning cotton 51 from the discharge port 52 to the collection cylinder. That is, through the setting of the driving component 6, the purpose of loading and collecting the vaccine stock solution and squeezing out part of the vaccine stock solution in the cleaning cotton 51 into the collection cylinder can be achieved at the same time. Among them, the elastic component 73 is a compression spring.

[0054] Refer to the instruction manual Figure 1-Figure 3 and Figure 8-Figure 9 A cylinder rack 8 is installed on the machine 1, a flat groove 801 is provided on the side wall of the cylinder rack 8, an inclined groove 802 is provided at one end of the flat groove 801, a connecting rod 81 is provided on the cylinder rack 8, the connecting rod 81 slides in the flat groove 801 and the inclined groove 802, one end of the connecting rod 81 located inside the cylinder rack 8 is movably plugged into the upper end of the inner side of the cylinder rack 8, a pressure cover 9 is installed at the end of the connecting rod 81 away from the cylinder rack 8, the pressure cover 9 is used to cover the prism 21, an elastic component 82 is sleeved on the upper end of the connecting rod 81, and the elastic component 82 is used to reset the connecting rod 81 downward, and a rotating drive component 83 is installed on the upper end of the cylinder rack 8, and the output end of the rotating drive component 83 is slidably plugged into the upper end of the connecting rod 81.

[0055] It should be noted that when the pressure cover 9 is covered on the prism 21, the connecting rod 81 is driven to rotate by the rotating driving component three 83. The connecting rod 81 first moves on the flat groove 801, and then moves from the flat groove 801 to the inclined groove two 802 under the action of the elastic component two 82. In the process of moving from the flat groove 801 to the inclined groove two 802, the connecting rod 81 drives the pressure cover 9 to cover the upper surface of the prism 21. When the pressure cover 9 is taken out from the prism 21, the connecting rod 81 can be driven to rotate in the opposite direction by the rotating driving component three 83, wherein the elastic component two 82 is a compression spring and the rotating driving component three 83 is a motor.

[0056] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
