Description

Technical Field

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

[0002] Vaccine refers to a preventive biological product used for human vaccination in order to prevent and control the occurrence and spread of infectious diseases. Biological products refer to preparations for prevention, diagnosis and treatment prepared from microorganisms or their toxins, enzymes, human or animal serum, cells, etc. Biological products for vaccination include vaccines, bacterial vaccines and toxoids. Among them, those made from bacteria are bacterial vaccines; those made from viruses, rickettsia, and spirochetes are vaccines, which are sometimes collectively referred to as vaccines.

[0003] Purification is a key step in the vaccine production process to ensure the safety and effectiveness of the final product. Vaccine purification is an extremely important step in the vaccine production process. Its purpose is to remove impurities introduced during the production process to ensure the safety and effectiveness of the final product. The purification step is usually carried out after the vaccine antigen has been produced (such as cell culture, virus culture, etc.) to remove non-target components produced during the production process, such as cell debris, culture medium components, viral vectors, etc., thereby increasing the concentration and purity of the target antigen to ensure the effectiveness of the vaccine.

[0004] After purification is completed, especially after stratification by an ultra-high-speed refrigerated centrifuge, qualified stock solution needs to be collected. In the prior art, pumps and pipelines are used to collect the vaccine stock solution after centrifugal stratification, that is, the supernatant separated after centrifugation is collected, and in order to ensure the quality of the collected stock solution, it is necessary to continuously detect the stock solution during the collection process. Among them, since the online refractometer can quickly and effectively detect the concentration of the fluid, the prior art needs to set an online refractometer on the collection pipeline to detect the concentration of the fluid (that is, the vaccine stock solution) flowing through it, and then collect the vaccine stock solution separately through different filling pipelines according to the detection standard.

[0005] Among them, for some vaccine concentrates, after purification and separation, in order to avoid long-term exposure to air or light that affects its activity and stability, the concentrate needs to be collected in a timely and rapid manner, which increases the flow rate in the delivery pipeline. At this time, if the flow rate is too fast, the fluid may not have enough time to contact the refractive prism of the online refractometer, resulting in unstable measurement results and affecting the accuracy of distinguishing the collected concentrate. In addition, during collection, as the concentrate in the centrifuge storage container gradually decreases, some impurities will inevitably be mixed in when it is collected to the solid-liquid separation surface. When the impurities move with the concentrate, if the movement speed is too fast, they will contact the prism surface of the online refractometer, which may easily cause minor damage to the prism. Long-term use will also affect the detection effect and accuracy. Summary of the invention

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Refer to the instruction manual Figures 1 to 13 A fully automatic online fluid collection device comprises a machine base 1, on which a slow-flow tank 2, a filling tube 3 and a collecting pump 4 are arranged, the collecting pump 4 is connected with the slow-flow tank 2 through a liquid delivery tube 41, the slow-flow tank 2 is connected with the filling tube 3 through a liquid outlet tube 21, wherein a plurality of groups of filling tubes 3 are arranged, the liquid outlet tube 21 is connected with each filling tube 3 through a branch tube, each filling tube 3 is provided with an independently controlled filling control valve 31, the liquid extraction tube of the collecting pump 4 is connected to the vaccine storage container after centrifugation by the centrifuge, and extends to the vaccine stock solution (supernatant).

[0035] A detection component 5 is provided on the slow flow tank 2, and the detection component 5 includes a mounting shell 51, and an online refractometer 52 is installed inside the mounting shell 51. The detection end of the online refractometer 52 extends to the inner wall of the slow flow tank 2, wherein the cross-sectional area of ​​the slow flow tank 2 is larger than the cross-sectional areas of the liquid delivery pipe 41 and the liquid outlet pipe 21. Therefore, when the collection pump 4 extracts a certain flow rate of the collected fluid, the diameter of the slow flow tank 2 is relatively large, and the fluid flow rate in the slow flow tank 2 is relatively small, so that the fluid flow rate flowing through the detection end of the online refractometer 52 is relatively reduced, so that the online refractometer 52 has sufficient time to detect the fluid, thereby improving the detection stability and detection effect. Even if the collected fluid contains solid impurities, the flow velocity of the impurities in the slow flow tank 2 is relatively small, the kinetic energy is small, and the damage to the key components in the detection end of the online refractometer 52 is small, which can ensure that the equipment still has a high detection accuracy when used for a long time.

[0036] Among them, the present device can also add other corresponding detection equipment as needed. For example, a detection sensor assembly 53 is also arranged in the mounting shell 51. The detection sensor assembly 53 includes a detection probe. The above-mentioned detection probe extends into the inner wall of the slow flow tank 2. Specifically, the detection sensor assembly 53 includes a pressure sensor, a temperature sensor, and a pH value sensor, etc. The probe of each sensor extends into the slow flow tank 2 to contact the fluid, so as to provide more detection data for vaccine production.

[0037] In this embodiment, a control host 12 is also provided in the base 1. The control host 12 is a commonly used touch-screen control host, which is compatible with the online refractometer 52 and controls the filling control valve 31. Therefore, in actual use, the collected vaccine concentrate can be classified according to the real-time detection data of the online refractometer 52, and then the corresponding filling control valve 31 is controlled to open, so that the vaccine concentrate can be filled into the filling container by the filling tube 3 at this position. A storage slot 11 is provided at the position corresponding to the filling tube 3 on the base 1. The storage slot 11 is used to place the filling container. An electronic scale 14 is provided in the storage slot 11. The electronic scale 14 is used to weigh the filling container so as to obtain the storage situation in the filling container, which is uniformly controlled by the control host 12.

[0038] It should be noted that the online refractometer 52 used in this embodiment is a commonly used detection instrument on the market. Its principle is that the light emitted from the LED enters the sapphire prism from one side of the sapphire prism through the optical fiber and reaches the contact surface between the prism and the fluid material. According to the different refractive indices of the fluid at the contact surface, a part of the light is totally reflected to the other side of the prism. The position of the totally reflected light will change due to the change of the critical angle (the critical angle will be different due to the different refractive indices of the fluid). The linear array CCD is used to accurately detect the position of the totally reflected light, and each position corresponds to a corresponding refractive index, thereby determining the concentration of the fluid. Since it is already a widely used existing technology, this embodiment will not explain it in detail.

[0039] In the above embodiment, since the cross-section of the slow-flow tank 2 is relatively large, in order to ensure that the fluid flows evenly and stably through the online refractometer 52 on the slow-flow tank 2, it is necessary to set the liquid delivery pipe 41 and the liquid outlet pipe 21 at the two ends of the slow-flow tank 2 respectively. In this embodiment, the slow-flow tank 2 is vertically arranged, the liquid outlet pipe 21 is arranged at the top of the slow-flow tank 2, and the liquid delivery pipe 41 is connected to one side of the bottom of the slow-flow tank 2, so that a slow flow from bottom to top can be formed in the slow-flow tank 2, avoiding the impact of the fluid when flowing from top to bottom, and reducing the damage to the substances in the vaccine stock solution fluid. At the same time, the embodiment used The collection pump 4 can be a peristaltic pump, which does not require blades and will not cause impact damage to the substances in the fluid. Under the above design, after collecting the fluid, there will be a lot of residue in the slow-flow tank 2. Therefore, a lifting seat 6 is provided at the bottom of the inner cavity of the slow-flow tank 2. The lifting seat 6 is slidably arranged in the slow-flow tank 2. A lifting drive 13 is provided on the base 1. The lifting seat 6 is installed on the output end of the lifting drive 13. The lifting drive 13 (such as a hydraulic cylinder) is used to drive the lifting seat 6 to rise and fall, so that after the use of the equipment is over, the lifting seat 6 can be driven to rise. Refer to the attached manual Figure 5 , the remaining fluid in the slow flow tank 2 can be lifted upward and fully discharged.

[0040] Furthermore, since there is a separation surface between the fluid and the solid in the centrifuge storage container, it is inevitable to collect a small amount of solid impurities when the fluid is actually collected. Therefore, in order to prevent the solid impurities from flowing into the sub-packaging container with the fluid, the present embodiment also provides the following technical solutions. For details, refer to the attached manual. Figure 2 The lifting seat 6 is located below the liquid delivery pipe 41, the online refractometer 52 is located in the upper and middle part of the slow flow tank 2, and a sedimentation tank 61 is provided at the top center of the lifting seat 6. The sedimentation tank 61 is used to accommodate the sediment of the fluid in the slow flow tank 2. Since the diameter of the slow flow tank 2 provided in this embodiment is relatively large, the upward flow velocity of the fluid in the slow flow tank 2 is relatively small. Therefore, in the slow flow tank 2, due to the decrease in the fluid movement velocity, the impurities in the fluid will produce corresponding precipitation. Due to the setting of the sedimentation tank 61 in the lifting seat 6, the impurity precipitation will be located below the liquid delivery pipe 41 and will not affect the entry of new fluid.

[0041] In the above embodiment, since the total amount of vaccine is large during the vaccine production process, multiple groups of centrifugal devices are usually used. Therefore, after the extraction and detection of the vaccine stock solution in one group of centrifugal devices are completed, the collection pipeline of the collection pump 4 needs to be transferred to the storage container of another group of centrifuges. Therefore, in the actual use of the equipment, air will inevitably mix into the fluid to form bubbles. If the bubbles adhere to the detection end of the online refractometer 52, it will affect the detection of the online refractometer 52. Therefore, refer to the attached manual for details. Figure 6 , this embodiment can improve the adaptation mode of the liquid delivery pipe 41 and the slow flow tank 2. Specifically, the slow flow tank 2 is a cylindrical structure, and the delivery direction of the liquid delivery pipe 41 is set tangentially along the circumference of the inner wall of the slow flow tank 2, that is, the fluid input into the slow flow tank 2 by the liquid delivery pipe 41 will produce a certain rotation, thereby causing the fluid in the slow flow tank 2 to be in a spiral upward state. Under the centrifugal force of the fluid, since the fluid density is greater than the bubble density, the fluid tends to move outward under the influence of centrifugal force, thereby causing the bubbles to tend to gather toward the center (refer to the tornado-shaped bubbles formed by shaking the water bottle), thereby reducing the adhesion of bubbles to the inner wall of the slow flow tank 2, thereby avoiding the influence of bubbles flowing through the detection end of the online refractometer 52 on real-time detection.

[0042] It should be noted that in addition to the arrangement of the liquid delivery pipe 41 to drive the fluid in the slow flow tank 2 to rotate, other driving structures can also be arranged to drive the fluid to rotate. The rotation of the fluid can not only reduce the adhesion of bubbles to the inner wall of the slow flow tank 2, but also form centrifugal force on the solid impurities in the fluid. Since the density of solid impurities is greater than the density of the fluid, the solid impurities tend to move toward the periphery under the influence of centrifugal force, thereby improving the separation effect of the sedimentation and the quality of the collected fluid. At the same time, the rotation of the fluid in the slow flow tank 2 can enable the fluid area in the slow flow tank 2 to form an effective exchange, avoid the single detection of the online refractometer 52, and enrich the detection effect.

[0043] In the above embodiment, if the device needs to be used continuously for a long time, the sediment in the sedimentation tank 61 will gradually increase. In order to avoid excessive sedimentation, refer to the attached manual. Figures 7 to 11 , this embodiment also provides the following technical solutions. Specifically, a discharge hole 22 is provided on the top side wall of the inner cavity of the slow-flow tank 2, and a blocking ring 23 is provided at a position corresponding to the discharge hole 22 in the inner cavity of the slow-flow tank 2. The blocking ring 23 is slidably installed in the slow-flow tank 2. A discharge cavity 7 is provided on the outside of the top of the slow-flow tank 2. The discharge cavity 7 is connected with the discharge hole 22. When the blocking ring 23 coincides with the discharge hole 22, the discharge hole 22 is blocked. Then, after the equipment has been used for a period of time, the lifting seat 6 can be controlled to rise, and the excess impurity precipitation can be lifted upward. At this time, the blocking ring 23 is controlled to move and staggered with the discharge hole 22, so that the inner cavity of the slow-flow tank 2 can be connected with the discharge cavity 7 through the discharge hole 22, so that the excess impurity precipitation can enter the discharge cavity 7. It should be noted that when the lifting seat 6 rises, the collection pump 4 is suspended, and the fluid is not input into the slow-flow tank 2 at this time.

[0044] Furthermore, the lifting seat 6 includes a piston base 62 and a rotating seat 63. A sealing structure is arranged between the piston base 62 and the slow flow tank 2. The piston base 62 is fixedly mounted on the output end of the lifting drive 13. The rotating seat 63 is mounted on the piston base 62. The sedimentation tank 61 is located at the top of the rotating seat 63. An elastic membrane layer 64 is fixedly mounted on the top of the rotating seat 63. When the elastic membrane layer 64 is concave and fits the rotating seat 63, a sedimentation tank 61 is formed on the top of the elastic membrane layer 64 to accommodate the precipitation of impurities. An air pipe 66 is arranged in the piston base 62. The air pipe 66 is connected to the air pump structure. An air vent is arranged in the rotating seat 63. The air vent is used to connect the space between the elastic membrane layer 64 and the rotating seat 63 with the air pipe 66. Then, after the lifting seat 6 is lifted upward, the air pump structure is used to inflate the inner side of the elastic membrane layer 64 so that the elastic membrane layer 64 bulges upward to form a protruding structure. Please refer to the attached manual for details. Fig. 9 , which helps to fully discharge the impurities originally stored in the sedimentation tank 61 into the discharge chamber 7.

[0045] It should be noted that, in addition to inflating the elastic membrane layer 64 when discharging the sediment, during the actual collection process, that is, when the lifting seat 6 is in the lower position, the elastic membrane layer 64 can also be inflated as needed, thereby relatively increasing the pressure in the slow flow tank 2, which helps the bubbles to move upward quickly and leave the area of ​​the online refractometer 52. In addition, the pressure can be increased by controlling the lifting seat 6 to rise, thereby accelerating the rise of the bubbles.

[0046] Furthermore, a lifting protrusion 642 is fixedly connected to the top center of the elastic membrane layer 64, and a lifting portion 231 is fixedly connected to the center of the sealing ring 23 through a connecting rod. The lifting portion 231 is correspondingly arranged to the lifting protrusion 642. When the lifting seat 6 is lifted and the elastic membrane layer 64 bulges, the lifting portion 231 can be lifted with the help of the lifting protrusion 642, thereby making the sealing ring 23 leave the discharge hole 22 and make the discharge hole 22 conductive.

[0047] Based on the above-mentioned improvements to the lifting seat 6, the present embodiment also provides another scheme for driving the fluid in the slow flow tank 2 to rotate. Specifically, the rotating seat 63 is rotatably installed on the piston base 62, and a sealing structure is arranged between the rotating seat 63 and the piston base 62. A driving motor 67 is fixedly installed in the piston base 62. The driving motor 67 is connected to the rotating seat 63 through a gear set, so as to be able to rotate and drive the rotating seat 63. A plurality of stirring ridges 641 are fixedly connected to the top center of the elastic membrane layer 64. In actual use, the driving motor 67 can be used to drive the rotating seat 63 to rotate, and the stirring ridges 641 are used to make the fluid at the center of the slow flow tank 2 rotate, thereby driving the fluid in the slow flow tank 2 to rotate, thereby achieving control of bubbles and acceleration of impurity precipitation.

[0048] In addition, when the lifting seat 6 is lifted and the elastic film layer 64 bulges, the rotating seat 63 can also be controlled to rotate, so that the sediment remaining on the surface of the elastic film layer 64 moves outward under the influence of centrifugal force, thereby improving the discharge effect of impurities.

[0049] It should be noted that a centralized pipeline can be set on the piston base 62 to accommodate the control line of the drive motor 67 and the air pipe 66, and the centralized pipeline is led out from the bottom of the slow flow tank 2 without affecting the control of the drive motor 67 and the elastic membrane layer 64. Since the swivel seat 63 and the piston base 62 rotate relative to each other, an air equalizing groove 65 can be set in the piston base 62. The air equalizing groove 65 is an annular structure, and the air holes in the swivel seat 63 are set corresponding to the air equalizing groove 65, and the air pipe 66 is connected to the air equalizing groove 65.

[0050] When the device is used for a long time, fluid residue will form inside the device. In order to avoid contamination when it is used next time, this embodiment also provides a cleaning solution. For details, refer to the attached manual. Figure 2 A cleaning pump 8 is also installed on the base 1. A cleaning pipe 81 is provided at the output end of the cleaning pump 8. The cleaning pipe 81 is connected to the liquid outlet pipe 21. A cleaning control valve 82 is provided on the cleaning pipe 81. The input end of the cleaning pipe 81 is connected to the clean water storage device through a pipeline. After the equipment is used, the cleaning control valve 82 can be opened, the dispensing control valve 31 can be closed, and clean water can be injected into the liquid outlet pipe 21 through the cleaning pump 8. After the equipment is used, the sediment needs to be discharged first. Please refer to the attached manual. Fig.12, after the lifting seat 6 is lifted and the elastic membrane layer 64 is bulged, clean water is first injected into the slow flow tank 2 for primary cleaning. At this time, the discharge pipe mouth of the discharge chamber 7 can be opened to allow the cleaning liquid to flow out, thereby achieving sufficient discharge of the sediment and effective cleaning of the discharge chamber 7. Then, the lifting seat 6 is controlled to reset and move to the bottom of the liquid delivery pipe 41, and then the cleaning pump 8 is turned on again to inject clean water into the slow flow tank 2, so that the clean water completely flows through the slow flow tank 2 and the liquid delivery pipe 41 to achieve secondary cleaning. Then, repeated cleaning can ensure that the equipment is clean and tidy without affecting subsequent use.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
