Description

Technical Field

[0001] This invention relates to the field of vaccine testing, and in particular to a vaccine testing device and a vaccine testing method. Background Technology

[0002] The basic steps of the existing vaccination process are as follows.

[0003] Step 1: First, the recipient (including guardian) should make an online appointment in advance or register the information of the vaccine to be administered at the registration desk.

[0004] Step 2: The vaccination management system transmits the registered vaccine information and recipient information to the vaccination nurse's workstation in some form (including but not limited to paper vaccination forms).

[0005] Step 3: The vaccination nurse retrieves the vaccine from the vaccine management equipment (cold chain) according to the received information and prepares the vaccination agent according to the standard procedure.

[0006] Step 4: The vaccination nurse administers the medication to the recipient at the injection site according to the correct route of administration (e.g., injection, oral administration, nasal spray).

[0007] During this process, vaccine recipients are very concerned about whether the vaccine that enters their bodies is consistent with the vaccine information specified in the vaccination registration. For example, whether the vaccine name is correct, whether the vaccine is expired, whether a low-priced vaccine has been used to replace a high-priced vaccine (such as a domestically produced vaccine replacing an imported vaccine), whether the vaccine vial is damaged or leaking, and whether the vaccine vial has been contaminated or deteriorated after being opened. Therefore, identifying whether the real vaccine entering the body is consistent with the vaccine registered for vaccination and whether the vaccine quality is reliable are matters of great concern to vaccine recipients, vaccination nurses, and the entire vaccine management system.

[0008] If the vaccine administered is inconsistent with the registered vaccine, suspected to be inconsistent, or has potential quality issues, it will have a serious impact. For example: 1) Vaccine recipients are not protected by effective vaccine antibodies, and their bodies are threatened by viral infection; 2) Deteriorated or incorrect vaccines can cause new diseases in recipients; 3) It increases conflicts between doctors and patients and disrupts the security management of vaccination sites; 4) Reduce public trust in the vaccination management system.

[0009] Identifying whether the vaccine directly administered to the recipient matches the vaccine information specified in the vaccination registration is a crucial measure in the closed-loop management system for immunization, carrying significant importance and far-reaching responsibility. How to identify the authenticity of vaccines has become a pressing technical problem that the industry needs to solve.

[0010] If manual identification is attempted, it is difficult for the human eye to observe the small size of vaccine vials, and subtle defects are not easily visible. Currently, there are three main solutions to these technical problems: Option 1 involves taking photos of the vaccine box and vial during the vaccination phase. This option only addresses the issue of image retention, not the identification problem. Furthermore, vaccine vials are typically cylindrical, making them difficult to photograph clearly.

[0011] Option 2 involves taking photos of the vaccine box during the vaccination phase using OCR (Optical Character Recognition) to obtain vaccine information. However, since the vaccine information is distributed across multiple sides of the vaccine box, it is difficult to collect complete information. Furthermore, the vaccine box does not fully represent the vaccine itself, making it difficult to ensure that this information is consistent with the vaccine administered to the recipient.

[0012] Option 3 involves scanning the National Medical Products Administration's vaccine traceability code on the vaccine box to obtain vaccine information that the vaccine manufacturer has registered in advance on the management platform. This method provides comprehensive, accurate, and highly reliable vaccine information. However, the vaccine box and the vaccine itself are not the same item, so it is still difficult to ensure that the traceability code information is consistent with the vaccine administered to the recipient. Moreover, obtaining this information requires payment, which increases the implementation cost.

[0013] None of the above methods can effectively and quickly obtain vaccine information, making it difficult to determine the authenticity of vaccines. Therefore, a device is needed to quickly obtain information from the smallest packaging unit of a vaccine. Summary of the Invention

[0014] This invention provides a vaccine testing device and a vaccine testing method that can quickly obtain information about the smallest packaging of a vaccine.

[0015] On one hand, the present invention provides a vaccine testing device, including a base, an optical acquisition module, and a rotating device; The optical acquisition module is used to acquire optical information of the vaccine; both the optical acquisition module and the rotating device are disposed on the base, and at least one of them is slidably disposed on the base so that they can move closer or further away from each other, thereby clamping or releasing the vaccine vial. The rotating device includes a rotary motor and two rollers; the two rollers are arranged side by side with a gap between them, and are both positioned opposite the optical acquisition module. The two rollers and the optical acquisition module are used to clamp the vaccine vials; the rotary motor is driven to the rollers to drive the two rollers to rotate simultaneously, thereby causing the vaccine vials to rotate around their own axis.

[0016] The roller includes a central shaft, a hard sleeve, and a soft sleeve. The hard sleeve is fixedly sleeved between the central shaft and the soft sleeve. The central shaft is connected to the rotary motor. The soft sleeve is used to abut against the vaccine vial.

[0017] Both rollers are rotatably connected to the top of the base; Each of the central shafts is fixed with a driven gear, and the output shaft of the rotary motor is connected to a driving gear. The driving gear meshes with two driven gears simultaneously. A first mounting plate is provided below the base, and both ends of the first mounting plate are bent toward the base and fixedly connected to the base. The driving gear and the two driven gears are both disposed between the base and the first mounting plate, and the rotary motor is fixed below the first mounting plate.

[0018] The optical acquisition module is slidably mounted on the base; The vaccine testing equipment also includes a translation device, which is disposed on the base and includes a translation drive and a buffer assembly. The translation drive is connected to the optical acquisition module through the buffer assembly to drive the optical acquisition module to move closer to or away from the rotating device, thereby clamping or releasing the vaccine vial.

[0019] The translation device further includes a slider. Two parallel guide rails are provided on the base, and the two ends of the slider are slidably connected to the two guide rails respectively. The slider is connected between the buffer assembly and the translation drive. The slider slides relative to the base under the drive of the translation drive, thereby driving the buffer assembly and the optical acquisition module to translate.

[0020] The slider has a strip groove on the side facing the base, and the strip groove extends along the arrangement direction of the two guide rails. The translation drive includes a translation motor and a swing arm. The end of the swing arm is provided with a linkage block, which is slidably disposed in a strip groove. The output shaft of the translation motor is connected to the swing arm to drive the swing arm and the linkage block to rotate vertically. At the same time, the linkage block slides in the strip groove, thereby driving the slider to slide along the guide rail.

[0021] The buffer assembly includes two movable rods, a buffer component, and a connecting block. The movable rods are arranged side by side between the two guide rails and are parallel to the guide rails. One end of the movable rod is slidably engaged with the slider, and the other end is connected to the connecting block. The buffer component is sleeved on the outside of each movable rod and is located between the slider and the connecting block. The connecting block is connected to the optical acquisition module.

[0022] The vaccine testing equipment further includes a processor; the processor is electrically connected to the optical acquisition module, the translation device, and the rotation device to process the data from the optical acquisition module and control the operation of the rotation device and the translation device.

[0023] On the other hand, the present invention provides a vaccine testing method, comprising the following steps: Take the smallest packaged vaccine vial; The vaccine vial is placed between the optical acquisition module and the rotating device, and the vaccine vial is kept in contact with the acquisition surface of the optical acquisition module. The rotating device drives the vaccine vial to rotate around its own axis, thereby activating the optical acquisition module to collect optical information from the lateral surface of the vaccine vial. The optical information of the lateral surface of the vaccine vial is identified and determined.

[0024] The step of identifying and determining the lateral surface optical information of the vaccine includes: The optical information of the lateral surface of the vaccine vial is identified to obtain basic information about the vaccine, including vaccine label information, vaccine information, and vaccine vial information. The determination of the basic information includes: determining whether the vaccine vial is normal based on the vaccine vial information; comparing the vaccine label information with the recipient's scheduled vaccination information; and comparing the vaccine dosage information with preset information indicating a normal vaccine dosage status. The vaccine testing equipment and method provided by this invention can clamp the vaccine between a movable optical acquisition module or a rotating device; a rotary motor drives two rollers to rotate simultaneously, thereby causing the vaccine vial to rotate around its own axis; through the two rollers and the optical acquisition module, three contact points with the vaccine vial can be formed, ensuring the stability of the vaccine vial's rotation; when the vaccine vial is reliably clamped and rotates stably, the optical acquisition module can collect optical information from the side of the vaccine vial, thereby quickly obtaining information about the vaccine vial, which is beneficial for the identification and judgment of vaccine information after information collection.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Please see Figure 1 and Figure 2 A preferred embodiment of the present invention provides a vaccine testing device, including a base 100, an optical acquisition module 200, a rotating device 300, a translational device 400, an interface device 500, and a processor 600. The base 100 provides support and mounting structure for the entire device. The optical acquisition module 200, the rotating device 300, and the translational device 400 are all disposed on the base 100. The translational device 400 drives the optical acquisition module 200 to move towards the rotating device 300, and the optical acquisition module 200 pushes the vaccine vial 900 to be clamped between the optical acquisition module 200 and the rotating device 300. The rotating device 300 can drive the vaccine vial 900 to rotate around its own axis. While the vaccine vial 900 rotates, the optical acquisition module 200 acquires optical information from the vaccine vial 900, and the vaccine can be tested using this optical information. The interface device 500 supplies power to the entire device, transmits the overall information of the device, and displays it. The processor 600 is electrically connected to the optical acquisition module 200, the rotating device 300, the translation device 400, and the interface device 500 to process the data from the optical acquisition module 200 and control the operation of the rotating device 300 and the translation device 400.

[0031] The base 100 is plate-shaped, which is easy to process and manufacture, reducing product costs. Of course, in other embodiments, the base can also be configured with other shapes or structures to facilitate support for other components.

[0032] like Figure 2 As shown, the optical acquisition module 200 is used to acquire optical information from the vaccine vial 900 and is disposed on the base 100. In this embodiment, the optical acquisition module 200 is slidably disposed on the base 100 and can move closer to or further away from the rotating device 300 under the drive of the translation device, thereby enabling the optical module and the rotating device 300 to clamp or release the vaccine vial 900.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, the rotating device 300 is mounted on the base 100 and includes a rotary motor 310 and two rollers 320. The two rollers 320 are arranged side by side with a gap between them, and each is positioned opposite the optical acquisition module 200. A collection space for accommodating the vaccine vial 900 is formed between the two rollers 320 and the optical acquisition module 200. The rotary motor 310 is driven by the rollers 320 to drive the two rollers 320 to rotate simultaneously, thereby causing the vaccine vial 900 to rotate around its own axis. Through the two rollers 320 and the optical acquisition module 200, three contact points with the vaccine vial 900 can be formed, ensuring the stability of the vaccine vial 900's rotation.

[0034] In the rotating device 300, two rollers 320 are arranged at intervals so that the two rollers 320 act on the vaccine vial 900 respectively, and the center distance between the two rollers 320 is large, which can accommodate vaccine vials 900 with larger diameters.

[0035] like Figure 5 As shown, the roller 320 includes a central shaft 322, a hard sleeve 323, and a soft sleeve 324. The hard sleeve 323 is fixedly sleeved between the central shaft 322 and the soft sleeve 324. The central shaft 322 is fixedly connected to the driven gear 321, and the soft sleeve 324 is used to abut against the vaccine vial 900. Through the cooperation of the central shaft 322 and the driven gear 321, the roller 320 can rotate under the drive of the driven gear 321. The connection between the hard sleeve 323 and the central shaft 322 can improve the overall structural strength of the roller 320; the outer layer of the soft sleeve 324 is in contact with the vaccine vial 900, which can avoid wear on the vaccine vial 900 and affect the test, while increasing the friction between the soft sleeve 324 and the vaccine vial 900, which is beneficial for the roller 320 to drive the vaccine vial 900 to rotate.

[0036] Each central shaft 322 is fixed with a driven gear 321, and the output shaft of the rotary motor 310 is connected to a driving gear 311, which meshes with both driven gears 321 simultaneously. By utilizing the engagement of the driving gear 311 with the two driven gears 321, the two rollers 320 can rotate synchronously, ensuring the uniformity of their rotation. This design is simple, easy to assemble, and provides stable and reliable operation. In other embodiments, the rotary motor 310 can also be connected to the two rollers 320 via chain drive, belt drive, or other methods.

[0037] The rotary motor 310 is a stepper motor to facilitate stable control of the rotational speed of the two rollers 320. The rotary motor 310 is connected to a stepper motor drive module 312, which can amplify and adjust the weak signal drive from the processor 600 to the stepper motor into a strong signal suitable for the normal rotation of the stepper motor.

[0038] like Figure 4 As shown, to facilitate the fixing of the rotary motor 310, a first mounting plate 130 is also provided below the base 100. The two ends of the first mounting plate 130 are bent toward the base 100 and fixedly connected to the base 100. The driving gear 311 and two driven gears 321 are all disposed between the base 100 and the first mounting plate 130, and the rotary motor 310 is fixed below the first mounting plate 130.

[0039] Both rollers 320 are rotatably connected above the base 100, allowing the vaccine vial 900 to be placed on the base 100 during testing. The rotary motor 310, driven gear 321, and driving gear 311 are all located below the base 100, concealing the drive and transmission structures below the base 100. This ensures a relatively simple structure above the base 100 and reduces the impact of environmental factors surrounding the test.

[0040] like Figure 2 As shown, the translation device 400 is disposed on the base 100 and includes a translation drive 410 and a buffer assembly 420. The translation drive 410 is connected to the optical acquisition module 200 through the buffer assembly 420 to drive the optical acquisition module 200 to move closer to or away from the rotating device 300 to clamp or release the vaccine vial 900. The buffer assembly 420 can buffer the driving force of the translation drive 410, so that the squeezing force of the optical acquisition module 200 on the vaccine vial 900 has a certain degree of flexibility, avoiding damage to the vaccine vial 900, ensuring the accuracy of the test, and is applicable to vaccine vials of various diameters.

[0041] In other embodiments, the translation device can be connected to the rotating device, the optical acquisition module is fixed to the base, and the translation drive is connected to the rotating device through a buffer assembly to drive the rotating device to move closer to or away from the optical acquisition module to clamp or release the vaccine vial. This is applicable to vaccine vials of various diameters and avoids damage to the vials. Alternatively, both the rotating device and the optical acquisition module can be slidably mounted on the base, with two translation devices connected to the rotating device and the optical acquisition module respectively, allowing the rotating device and the optical acquisition module to move closer to or away from each other. Alternatively, the translation device can be omitted, and the vaccine vial can be placed directly between the rotating device and the optical acquisition module. This is only applicable to vaccine vials of specific diameters. In this case, an elastic mechanism can be provided between the rotating device and the optical acquisition module to keep them close to each other, clamping the vaccine vial while allowing them to move closer to or away from each other. As can be seen from the above, at least one of the optical acquisition module and the rotating device is slidably mounted on the base, allowing them to move closer to or away from each other to clamp or release the vaccine vial. By moving the optical acquisition module or rotating the device, the vaccine can be held between the two.

[0042] like Figure 2 As shown, the translation device 400 and the optical acquisition module 200 are connected to form a detection assembly. There are two sets of detection assemblies, which are symmetrically arranged on both sides of the rotating device. By using one rotating device, two vaccine vials can be rotated and optical information can be acquired at the same time to improve detection efficiency.

[0043] like Figure 2 , Figure 6 As shown, the translation device 400 also includes a slider 430. Two parallel guide rails 110 are provided on the base 100, and the two ends of the slider 430 are slidably connected to the two guide rails 110 respectively. The slider 430 is connected between the buffer assembly 420 and the translation drive 410. Driven by the translation drive 410, the slider 430 slides relative to the base 100, thereby driving the buffer assembly 420 and the optical acquisition module 200 to translate. The cooperation between the slider 430 and the two guide rails 110 ensures the smooth movement of the buffer assembly 420 and the optical acquisition module 200. This reduces the shaking of the optical acquisition module 200 during movement, ensuring that the vaccine vial 900 can be smoothly pushed to the two rollers 320, preventing the vaccine vial 900 from tipping over.

[0044] like Figure 2 As shown, each guide rail 110 has a support seat 111 at both ends, so that the guide rail 110 and the base 100 are spaced apart. The guide rail 110 is rod-shaped and has a slider 430 passing through it. A linear bearing is provided between the two to reduce the friction between the slider 430 and the guide rail 110 and ensure the smooth sliding of the slider 430 relative to the guide rail 110.

[0045] like Figure 7 As shown, a strip groove 432 is provided on the side of the slider 430 facing the base 100, and the strip groove 432 extends along the arrangement direction of the two guide rails 110. The translation drive 410 includes a translation motor 411 and a swing arm 412. A linkage block 413 is provided at one end of the swing arm 412. The linkage block 413 is slidably disposed in the strip groove 432. The output shaft of the translation motor 411 is connected to the swing arm 412 to drive the swing arm 412 and the linkage block 413 to rotate vertically. At the same time, the linkage block 413 slides in the strip groove 432, thereby driving the slider 430 to slide along the guide rail 110.

[0046] After the translation motor 411 is started, it can drive the swing arm 412 and the linkage block 413 to rotate vertically. While the linkage block 413 rotates with the swing arm 412, it slides along the length of the strip groove 432. By utilizing the cooperation between the linkage block 413 and the strip groove 432, the slider 430 reciprocates along the guide rail 110. This structure can easily control the stroke of the slider 430 and avoid excessive pressure on the vaccine vial 900 due to excessive sliding distance of the slider 430.

[0047] The translation motor 411 is a DC motor and is connected to a DC motor drive module 414. The DC motor drive module 414 can amplify and adjust the weak signal from the processor 600 to drive the DC motor into a strong signal suitable for the normal rotation of the DC motor.

[0048] like Figure 2 , Figure 3, Figure 4 As shown, the slider 430 and the translation motor 411 are respectively placed on the upper and lower sides of the base 100. The slider 430 is located above the base 100, which can facilitate the movement of the optical acquisition module 200. The translation motor 411 is located below the base 100, which can avoid interfering with the movement of the slider 430. The layout is reasonable and facilitates the assembly and connection of the translation motor 411, the slider 430 and the base 100.

[0049] A clearance groove 141 is provided on the base 100 at a position corresponding to the movement range of the swing arm 412. A boss 431 is provided on the bottom of the slider 430, and a strip groove 432 is located on the boss 431. The boss 431 is located in the clearance groove 141. By utilizing the cooperation between the boss 431 and the clearance groove 141, the distance between the slider 430 and the swing arm 412 can be shortened, facilitating the cooperation between the linkage block 413 and the strip groove 432. The boss 431 moves in the clearance groove 141, which can limit the movement range of the slider 430, avoid excessive compression of the vaccine vial 900, and ensure the safety of equipment operation.

[0050] like Figure 7 , Figure 8 As shown, the linkage block 413 is a vertically arranged cylindrical shape that is rotatably connected to the swing arm 412 around its own axis. The outer diameter of the linkage block 413 is smaller than the width of the strip groove 432, so that the outer wall of the linkage block 413 and the groove wall of the strip groove 432 roll into each other, reducing the friction between them and improving the stability of the movement between the swing arm 412 and the slider 430.

[0051] like Figure 8 As shown, two clamping portions 4121 are provided on the end of the swing arm 412 away from the linkage block 413. Both clamping portions 4121 are strip-shaped extending along the length direction of the swing arm 412. The two clamping portions 4121 are spaced apart, and bolts (not shown in the figure) are provided on the ends of both away from the linkage block 413. The output shaft of the translation motor 411 is clamped and fixed between the two clamping portions 4121. The two clamping portions 4121 facilitate the assembly and connection between the swing arm 412 and the translation motor 411.

[0052] Furthermore, a clamping groove 4120 is provided at one end of the two clamping parts 4121 near the linkage block 413. The output shaft of the translation motor 411 is fixed in the clamping groove 4120. The clamping groove 4120 can further facilitate the connection between the translation motor 411 and the swing arm 412. Moreover, the clamping parts 4121, their bolts, and the linkage block 413 are located on both sides of the output shaft of the translation motor 411, which helps to make the swing arm 412 more balanced and improve the stability of the rotation of the swing arm 412.

[0053] like Figure 4As shown, a second mounting plate 142 is provided below the base 100. Both ends of the second mounting plate 142 are bent toward the base 100 and fixedly connected to the base 100 to form a receiving space between them. The output shafts of the swing arm 412 and the translation motor 411 are located in this receiving space to avoid the rotation of the swing arm 412 being disturbed by external objects.

[0054] The translation motor 411 is fixedly connected to the second mounting plate 142, and the main body of the translation motor 411 is located below the second mounting plate 142 to facilitate the assembly and connection between the translation motor 411 and the second mounting plate 142. The bottom surface of the second mounting plate 142 is fixedly connected to the upper surface of the first mounting plate 130 through support columns to ensure that the second mounting plate 142 is firmly and reliably fixed.

[0055] The second mounting plate 142 extends toward the base plate to form a limiting portion 1421. The limiting portion 1421 is vertically arranged, passes through the clearance groove 141, protrudes from the base 100 at the top, and bends toward the slider 430. The limiting portion 1421 can further limit the slider 430 and prevent external objects from entering the range of motion of the slider 430, thus ensuring the stability of the slider 430's operation.

[0056] like Figure 6 , Figure 7 ,and Figure 8 As shown, the buffer assembly 420 is used to buffer the vaccine vial 900 when it is pushed to the rotating device 300. It is connected between the optical acquisition module 200 and the slider 430, that is, the buffer assembly 420 is connected to the translation drive 410 through the slider 430.

[0057] The buffer assembly 420 includes two movable rods 421, a buffer element 422, and a connecting block 423. Two movable rods 421 are arranged side-by-side between two guide rails 110, and the movable rods 421 are parallel to the guide rails 110. One end of each movable rod 421 is slidably engaged with the slider 430, and the other end is connected to the connecting block 423. A buffer element 422 is fitted over each movable rod 421, located between the slider 430 and the connecting block 423; the connecting block 423 is connected to the optical acquisition module 200.

[0058] The movable rod 421 allows the connecting block 423 and the slider 430 to move closer or further apart. The two movable rods 421 ensure the stability of the connecting block 423 during movement, thereby ensuring the stability of the optical acquisition module 200 during movement.

[0059] When the slider 430 moves toward the rotating device 300 under the drive of the translation drive 410, the slider 430 pushes the optical acquisition module 200 and the rotating device 300 to move through the buffer assembly 420. The optical acquisition module 200 pushes the vaccine bottle 900 so that the vaccine bottle 900 is clamped between the optical acquisition module 200 and the rotating device 300, and the vaccine bottle 900 abuts against the optical acquisition module 200 and the two rollers 320. At this time, the slider 430 continues to move toward the rotating device 300, and the vaccine bottle 900 is clamped between the optical acquisition module 200 and the two rollers 320, and the vaccine bottle 900 moves toward the light. The optical acquisition module 200 provides a reaction force towards the slider 430. The buffer 422 is deformed by the slider 430 and the connecting block 423, so that the movement distance of the slider 430 and the optical acquisition module 200 towards the rotating device 300 is less than the movement distance of the slider 430. This avoids the vaccine bottle 900 from being over-compressed and damaged. At the same time, it can also ensure that the vaccine bottle 900 is clamped between the optical acquisition module 200 and the two rollers 320, so that the vaccine bottle 900 can rotate around its own axis under the drive of the two rollers 320. The optical acquisition module 200 can then scan and acquire data on the circumference of the vaccine bottle 900.

[0060] In this embodiment, the buffer 422 is a rubber tube sleeved over the movable rod 421, with its two ends abutting against the slider 430 and the connecting block 423 respectively. Buffering is achieved through the flexible deformation of the rubber material itself. In other embodiments, the buffer 422 can also be a compression spring or other deformable components.

[0061] The optical acquisition module 200 can be a linear scan CIS (Contact Image Sensor) or a macro camera.

[0062] like Figure 1 As shown, the vaccine testing equipment also includes a sensing device 700, which includes a first sensor 701 and a second sensor 702, both of which are located at the optical acquisition module. The first sensor can be a photoelectric sensor, an acoustic sensor, etc., used to detect the presence or absence of a vaccine vial, i.e., whether a vaccine vial is placed between the optical acquisition module and the rotating device. The second sensor can be a pressure sensor used to detect the pressure applied to the vaccine vial. Both the first sensor 701 and the second sensor 702 are electrically connected to the processor 600 to send the sensing signals to the processor 600 for further control of the operation of other components.

[0063] Once the vaccine vial is placed between the optical acquisition module and the rotating device, the voltage level of the first sensor changes. The processor reads this voltage level and controls the translation device to move, which in turn drives the optical acquisition module towards the rotating device. During the movement of the optical acquisition module, the second sensor monitors the pressure applied to the vaccine vial in real time. When the pressure reaches a set value, the processor stops the translation device and simultaneously controls the rotating device to drive the vaccine vial to rotate around its own axis.

[0064] like Figure 2 As shown, the vaccine testing equipment also includes two second sensors 702. These two second sensors 702 are disposed on the base 100 along the moving direction of the slider 430 and located on one side of the slider 430, for detecting the position of the slider 430. Through the two second sensors 702, the two positions of the slider 430 relative to the rotating device 300 can be detected to ensure that the slider 430 can move into position.

[0065] In this embodiment, the second sensor 702 is a photoelectric sensor, and a sensing plate 437 is provided on the side of the slider 430 facing the second sensor 702. The position of the slider 430 is detected by the cooperation of the sensing plate 437 and the photoelectric sensor. Here, the second sensor 702 can also be a position sensor, proximity switch, or other sensing components.

[0066] like Figure 1 As shown, the interface device 500 includes a power interface 501, a communication interface 502, and a display component 503. The power interface 501 supplies power to the entire device and can be connected to an external power source or use a battery. The communication interface 502 is used for information transmission, allowing the input of appointment vaccination information and the transmission of the device's overall recognition results. The display component 503 displays information, showing the overall information of the device. The power interface 501, communication interface 502, and display component 503 are all electrically connected to the processor 600.

[0067] In this embodiment, by setting up the interface device 500 and the processor 600, the vaccine testing equipment can analyze and determine whether the vaccine is abnormal after collecting the optical information of the vaccine vial 900. As another implementation method, the interface device 500 and the processor 600 can be omitted. The device can be electrically connected to the user's computer via a data cable, wireless communication module, etc. The driver and control software of the vaccine testing equipment can be installed on the computer, and the operation of the vaccine testing equipment and data display can be controlled by the computer, thereby reducing the overall cost of the vaccine testing equipment.

[0068] The present invention also provides a vaccine testing method, comprising the following steps.

[0069] Step S100, optical acquisition, in which optical information of the smallest packaging of the vaccine vial 900 before vaccination is acquired, specifically includes the following steps.

[0070] Step S110: Take the smallest package of vaccine vial.

[0071] In this step, the pre-vaccination vaccine information, including name and dosage, can be obtained based on the appointment registration information. Then, the corresponding vaccine box is taken out from the vaccine cold chain system, and the smallest package of the vaccine, namely the vaccine bottle, is taken out from it.

[0072] Step S120: Place the vaccine vial between the optical acquisition module and the rotating device, and keep the vaccine vial in contact with the acquisition surface of the optical acquisition module.

[0073] In this step, the optical acquisition module and the rotating device can move closer to or further apart to clamp and release the vaccine vial. When the vaccine vial is clamped by the optical acquisition module and the rotating device, the side surface of the vaccine vial and the acquisition surface of the optical acquisition module can remain in contact.

[0074] Furthermore, a translation device is used to drive the optical acquisition module to translate, allowing the optical acquisition module to move closer to or away from the rotating device. The acquisition surface of the optical acquisition module then pushes the vaccine vial towards the rotating device. This ensures that the acquisition surface of the optical acquisition module is in effective contact with the vaccine vial while it is being pushed, facilitating subsequent scanning of the vaccine vial by the optical acquisition module. In other embodiments, a translation device can also be used to drive the rotating device to move closer to or away from the optical acquisition module.

[0075] Step S130: Drive the vaccine vial to rotate around its own axis using the rotating device, and start the optical acquisition module to acquire optical information of the side surface of the vaccine vial.

[0076] Because the vaccine vial is in contact with the acquisition surface of the optical acquisition module, when the vaccine vial rotates around its own axis, the optical acquisition module can acquire optical information from the surface of the vaccine vial that is in contact with the acquisition surface.

[0077] In steps S120 and 130, preferably, the vaccine testing equipment provided in the foregoing embodiments can be used. Specifically, step S120 may include the following steps.

[0078] Step S121: Place the vaccine vial between the optical acquisition module and the rotating device of the vaccine testing equipment.

[0079] Step S122: Activate the translation device to drive the optical acquisition module toward the rotating device. As the optical acquisition module moves toward the rotating device, its acquisition surface first contacts the vaccine vial, then pushes the vaccine vial toward the rotating device until the vaccine vial is clamped between the optical acquisition module and the rotating device.

[0080] In this step, a sensing device can be installed at the acquisition surface of the optical acquisition module. This sensing device is used to detect the presence or absence of the vaccine vial and the pressure applied to it. The sensing device includes a first sensor and a second sensor. The first sensor can be a photoelectric sensor, an acoustic sensor, etc., used to detect the presence or absence of the vaccine vial, i.e., whether a vaccine vial is placed between the optical acquisition module and the rotating device. The second sensor can be a pressure sensor used to detect the pressure applied to the vaccine vial.

[0081] Once the vaccine vial is placed between the optical acquisition module and the rotating device, the voltage level of the first sensor changes. The processor reads this voltage level and controls the translation device to move, which in turn drives the optical acquisition module towards the rotating device. During the movement of the optical acquisition module, the second sensor monitors the pressure applied to the vaccine vial in real time. When the pressure reaches a set value, the processor stops the translation device and simultaneously controls the rotating device to drive the vaccine vial to rotate around its own axis.

[0082] More specifically, the translation device 400 includes a translation drive 410 and a buffer assembly 420, and the rotation device 300 includes a rotary motor 310 and two rollers 320. The translation drive 410 drives the optical acquisition module 200 to move toward the rotation device 300 via the buffer assembly 420, so that the vaccine vial 900 is clamped between the optical acquisition module 200 and the two rollers 320 of the rotation device 300.

[0083] After receiving the control signal from the processor 600, the DC motor drive module 414 amplifies and adjusts it to a cavity signal suitable for the normal rotation of the translation motor 411. After receiving the strong signal, the translation motor 411 starts to rotate and pushes the buffer assembly 420 to move in a straight line through the slider 430. The buffer assembly 420 is fixed together with the optical acquisition module 200 and can move forward and backward at the same time.

[0084] The optical acquisition module 200 propels the vaccine vial 900 forward, that is, towards the rotating device 300. During the forward movement, the buffer assembly, the optical acquisition module 200, and the vaccine vial 900 move forward together as a whole.

[0085] A contact line is formed between the optical acquisition module 200 and the vaccine vial 900, where the plane and the arc surface are tangent. Although the buffer component is elastic, it does not affect the three components from moving forward at the same speed when the forward resistance is small.

[0086] The vaccine vial 900 continues to move forward parallel to the roller 320 of the rotating device 300 and then continues to move forward after touching the soft sleeve 324.

[0087] Because the soft sleeve 324 of the roller 320 is elastic, the vaccine bottle 900 is in close contact with the cylindrical side soft sleeve 324 of the roller 320, forming two parallel contact lines with the two rollers 320 whose arc surfaces are tangent to each other.

[0088] The three contact lines formed are all parallel to the axis of the vaccine vial 900.

[0089] As the resistance to the forward movement of the optical acquisition module 200 increases, the buffer component 420 gradually compresses and deforms to provide a buffering effect. The continuous deformation of the buffer component 420 triggers the second sensor to detect the change in state, and the control signal of the processor 600 stops.

[0090] The position of the buffer assembly 420 remains unchanged, and the vaccine vial 900 is subjected to stable pressure from three contact surfaces facing the center and remains in a stable position.

[0091] Through the above steps, under the control of the processor 600, the translation device 400 translates the vaccine vial 900 to the designated accurate position, and makes the vaccine vial 900 receive a preset pressure value.

[0092] In step S130, after using the vaccine testing equipment of the aforementioned embodiment, more specifically, the two rollers 320 of the rotating device 300 drive the vaccine vial 900 to rotate around its own axis, and the optical acquisition module 200 acquires the optical information of the lateral surface of the vaccine vial 900.

[0093] In this step, the processor 600 controls the rotating device 300 to rotate the vaccine vial 900 to a stable speed. The specific processing flow is as follows.

[0094] 1) After receiving the control signal from the processor 600, the stepper motor drive module 312 amplifies and adjusts it into a strong signal suitable for the normal rotation of the rotary motor 310.

[0095] 2) After receiving a strong signal, the rotary motor 310 starts to rotate, which in turn drives the drive wheel to rotate.

[0096] 3) The driven wheels of the two rollers 320 mesh independently with the driving wheel, so the rotation of the driving wheel drives the two driven wheels to rotate together, and the rotation direction of the two driven wheels is opposite to the rotation direction of the driving wheel.

[0097] 4) The two rollers 320 rotate in the same direction and at the same speed, and the linear speed of the soft sleeve 324 covering the rollers 320 is also the same.

[0098] 5) The vaccine vial 900 is subjected to stable pressure from three contact surfaces facing the center. The soft sleeves 324 of the two rollers 320 rotate in the same direction and at the same speed, causing the vaccine vial 900 to rotate in the opposite direction under friction. The vaccine vial 900 and the two rollers 320 generate rotational power through contact friction. Therefore, the linear velocity of the tangential contact lines that are opposite to the rotation direction of the rollers 320 is the same.

[0099] Therefore, the processor 600 controls the rotating device 300 to rotate the vaccine vial 900 to a stable speed.

[0100] The optical acquisition module 200 can perform 360-degree rotational optical acquisition of the exterior and internal medication of the vaccine vial, and combine the data into a complete image. The image content includes at least the image of the vaccine vial 900 label, the color and shape of the vaccine medication, and the texture of the vaccine vial 900 body. The specific process is as follows.

[0101] 1) The optical acquisition module 200 keeps its position fixed, and the stationary acquisition surface is tangentially translated to the side of the rotating vaccine vial 900.

[0102] 2) The optical acquisition module 200 continuously acquires graphic information from the side of the vaccine vial 900 in small areas or vertical lines.

[0103] 3) After the vaccine vial 900 rotates continuously for a period of time, the optical acquisition module 200 acquires each area or each optical vertical line.

[0104] 4) Use AI algorithms to piece together each area or each vertical line to form a complete graphic.

[0105] The vaccine testing equipment provided by this invention has a power interface 501 of the interface device 500 for internal power supply, ensuring normal power-on operation of the entire device. The first sensor 701 continuously detects whether the vaccine vial 900 has been placed and waits for the processor 600 to collect its status. When the processor 600 detects through the first sensor 701 that the vaccine vial 900 has been placed in the designated area, the translation device 400 drives the optical acquisition module 200 to move forward. The optical acquisition module 200 moves the cylindrical vaccine vial 900 parallel forward, gradually approaching the two rollers 320 of the rotating device 300. The second sensor 702 continuously detects whether the vaccine vial 900 has reached the accurate position and waits for the processor 600 to collect its status. When the processor 600 detects through the second sensor 702 that the vaccine vial 900 has been translated to the accurate position, the vaccine vial 900 simultaneously contacts the optical acquisition module 200 and the two rollers 320, forming three parallel contact lines. Under the action of the buffer component 420, tight contact is achieved, and all three parallel lines exert force towards the center of the vaccine vial 900, thus stabilizing the vaccine vial 900. After the vaccine vial 900 reaches a stable state, the processor 600 controls the rotating device 300 to drive the vaccine vial 900 to rotate stably along its own axis. At the same time, the acquisition surface of the optical acquisition module 200 remains in a stable position. Under the combined action of the rotating vaccine vial 900 and the stable optical acquisition module 200, the tangent line between the side surface of the vaccine vial 900 and the acquisition surface of the optical acquisition module 200 continuously translates. The optical acquisition module 200 continuously acquires the tangentially translated image through the acquisition surface and continuously combines and stitches the image. After the optical acquisition is completed, a complete side scan image of the vaccine vial 900 is obtained. The optical acquisition module 200 then transmits the image to the processor 600. The processor 600 performs preliminary optimization processing on the image data to obtain the original complete image, which contains at least three types of basic graphics: Basic graphic 1: A graphic of the label containing vaccine vials 900; Basic graphic 2: Graphic of the vaccine preparation inside the transparent glass bottle; Basic graphic 3: The texture graphic of the non-optically obstructed part of the transparent glass bottle itself.

[0106] Step S200 involves identifying the optical information of the lateral surface of the vaccine vial. This step can be performed intelligently using a processor.

[0107] After obtaining the original complete lateral image of the vaccine vial 900 through optical acquisition in step S100, the processor 600 preprocesses the image again, including but not limited to image rotation, image stretching, image compression, image cutting, and color contrast enhancement. The processor 600 obtains the aforementioned three basic types of images and then intelligently identifies them using AI algorithms to acquire valid information about the vaccine vial 900. This includes, but is not limited to, single-item and simultaneous multi-item recognition of three basic types of information: vaccine label information, vaccine drug information, and vaccine vial body information, as detailed below.

[0108] Basic Information 1: Vaccine label information, information within the side label, including but not limited to identifying the vaccine name, production batch number, vaccine specifications, expiration date, manufacturer, brand, etc.

[0109] Basic Information 2: Vaccine drug information, which is the information of the drug inside the vaccine vial, including but not limited to the color and form of the vaccine drug, thereby identifying vaccine quality information such as whether the vaccine has changed color, whether it has coagulated, or whether it has nodules.

[0110] Basic Information 3: Vaccine vial information, including but not limited to identifying whether the vial cap has fallen off, information on cracks or breaks in the vial material, and the texture of the side surface of the vaccine vial itself.

[0111] By using the above three types of basic information, it is possible to independently determine whether the vaccine has expired, whether the vaccine has changed color, or whether the vaccine vial 900 has been broken, thereby determining whether the vaccine is safe and can be injected into the recipient's body, and thus identifying whether the vaccine vial 900 has been broken or leaked.

[0112] Step S300, Information Determination.

[0113] After obtaining the three basic types of vaccine information through intelligent identification in step S200, the information is compared with preset information to comprehensively determine the three levels of information and give a final conclusion.

[0114] Independent judgment: Based on the information of the vaccine bottle identified by the intelligent system, it determines whether the vaccine bottle is normal, such as whether the cap is detached, whether the bottle body has cracks, or whether it is broken.

[0115] Comparison and judgment: The system compares the vaccine information identified by the intelligent system with the preset information on the normal state of the vaccine stored in the processor. This can determine whether the vaccine is in a normal state, such as whether it has changed color, become cloudy, coagulated, or clumped.

[0116] First, the vaccine appointment information of the recipient is obtained using communication interface 502. This appointment information includes, but is not limited to, the vaccine name, manufacturer's name, batch number, expiration date, dosage, and specifications. Then, the vaccine label information is compared with the recipient's appointment information using intelligent recognition to determine basic conclusions, including but not limited to whether the vaccine name matches, whether the batch number matches, whether the vaccine is within its expiration date, whether the specifications are accurate, and whether the manufacturers are consistent.

[0117] Comprehensive assessment: Based on independent assessment and comparative assessment, an overall assessment is made to determine whether vaccination is appropriate.

[0118] After comprehensive judgment, the processor 600 displays the recognition process data and recognition results through the display component 503 of the interface device 500, or transmits the recognition process data and recognition results to other systems through the communication interface 502.

[0119] The vaccine detection design and method provided in this invention, taking actual Japanese encephalitis live attenuated vaccine vaccination as an example, are as follows: Figure 9 As shown, the application scenarios of this invention are as follows.

[0120] 1) Zhang San takes his child to make an online appointment or go directly to the community health center registration desk to confirm that the vaccine to be administered is the Japanese encephalitis live attenuated vaccine.

[0121] 2) The registration desk transmits the registered vaccine information to the vaccination station queuing system through the system's backend server.

[0122] 3) The vaccinating nurse calls Zhang San to the vaccination station in the queuing system to receive the live attenuated Japanese encephalitis vaccine.

[0123] 4) The vaccinating nurse confirms the personnel information and the pre-vaccination vaccine information, including the vaccine name, vaccine manufacturer name, vaccine production batch number, vaccine expiration date, vaccine dosage, and vaccine specifications.

[0124] 5) The nurse administering the vaccine takes out the live attenuated Japanese encephalitis vaccine box from the vaccine cold chain system and takes out 900 vials of vaccine from it.

[0125] 6) The nurse administering the vaccine inserts the live attenuated Japanese encephalitis vaccine vial 900 into the vaccine testing device provided by this invention.

[0126] 7) The first sensor 701 detects the insertion of the live attenuated Japanese encephalitis vaccine vial 900, thus changing the voltage level.

[0127] 8) When the processor 600 reads the change in the level state of the first sensor 701, it drives the translation motor 411 to rotate via the DC motor drive module 414.

[0128] 9) The translation motor 411 rotates and drives the slider 430 to move through the swing arm. The slider 430 moves forward together with the buffer assembly 420 and the optical acquisition module 200 fixedly connected to it.

[0129] 10) The glass mirror (collection surface) of the optical acquisition module 200 pushes the vaccine vial 900 to move together.

[0130] 11) When the vaccine vial 900 touches the two rollers 320 with soft sleeves 324, the buffer assembly 420 continues to move forward. The vaccine vial 900 is subjected to forward pressure from the glass mirror of the optical acquisition module 200 and reverse pressure from the two rollers 320. The three forces exert inward pressure at three points, and the position of the vaccine vial 900 reaches equilibrium and stops moving.

[0131] 12) As the translation motor 411 drives the slider 430 to move forward continuously, the pressure on the buffer component 420 gradually increases, changing the pressure sensed by the first sensor 701. When the pressure reaches the set value, it causes the state to change.

[0132] 13) When the processor 600 reads the change in the level state of the first sensor 701, it drives the rotary motor 310 to rotate via the stepper motor drive module 312.

[0133] 14) The rotary motor 310 drives the drive wheel to rotate.

[0134] 15) The driving wheel drives two identical driven wheels that mesh with it to rotate together. The two driven wheels have the same speed and direction, and the two driven wheels drive two rollers 320 to rotate.

[0135] 16) The soft sleeves 324 on the two rollers 320 rotate together in the same direction and at the same speed.

[0136] 17) Because the vaccine vial 900 has reached force balance, it is passively rotated together with the roller 320 in the opposite direction, but with the same linear speed.

[0137] 18) The vaccine vial 900 rotates continuously on the glass mirror of the stationary optical acquisition module 200.

[0138] 19) The optical acquisition module 200 continuously scans vertical lines in color, and the entire side of the vaccine vial 900 is acquired when it rotates more than one revolution.

[0139] 20) By sequentially piecing together each collected vertical line, a complete original scan image is formed, such as... Figure 10 As shown.

[0140] 21) Processor 600 optimizes the processing of the raw scan image.

[0141] 22) The processor 600 uses AI algorithms and other methods to segment three basic types of graphics: a) vaccine label graphics, such as... Figure 11 As shown; b) Vaccine formulation diagram, as shown Figure 12 As shown; c) Vaccine vial 900 texture graphic, as... Figure 13 As shown.

[0142] 23) The processor 600 intelligently identifies three types of basic information through AI algorithms and other methods.

[0143] a) Basic Information 1: Vaccine label information, including but not limited to, i. Vaccine name: Japanese encephalitis live attenuated vaccine; ii. Production batch number: 20200XXXXX-X; iii. Production date: February 26, 2020; iv. Valid until: August 25, 2021; v. Vaccine specifications: 1 dose / vial; vi. Manufacturer: [Company Name] Biological Products Research Institute Co., Ltd. vii. Brand: [Brand Name]; viii.LOGO; ix. National Drug Approval Number: SXXXXXXXX; b) Basic Information 2: Vaccine drug information, vaccine color is brown, nodule status.

[0144] c) Basic Information 3: Information on 900 vaccine vials: The vials have cracks and are suspected of leaking air.

[0145] 24) The processor 600 uses AI algorithms to comprehensively determine information. a) Independent assessment: Abnormal vaccine color, abnormal vaccine vial volume (900 units). b) Comparison and determination: The vaccine names are the same, the vaccine batch numbers are the same, and the vaccine has expired. c) Overall assessment: Vaccination is not recommended. 25) The display component 503 displays three types of basic graphics, three types of basic information, and three levels of information determination.

[0147] The vaccine detection method provided by this invention can be implemented using the vaccine detection equipment provided by this invention. Through the cooperation of the rotating device and the optical acquisition module, it can adapt to the identification of vaccine vials of various diameters and ensure the stability of the vaccine vial rotation.
