Description

Technical Field

[0001] The invention relates to the technical field of immune cell culture, in particular to an immune cell culture perfusion device. Background Art

[0002] White blood cells are an important type of immune cell in the body, responsible for protecting the human body from infection and other foreign invading substances. The main function of white blood cells is to identify, locate, and destroy invading external pathogens such as microorganisms and viruses, and to clear damaged or abnormal cells in the human body. White blood cells play a very important role in the entire immune system.

[0003] In order to explore the mechanism of the disease, culturing white blood cells in vitro and introducing stimuli such as pathogens and chemicals can simulate the immune response process in the body, which helps medical staff understand the nature of the disease and formulate treatment plans for patients with the disease; Currently, when perfusion culture of leukocytes in vitro is performed, a first pump body is required to be connected to a culture medium storage tank and a culture dish through water pipes, and then a second pump body is connected to the culture dish and a waste liquid recovery tank through water pipes. The first pump body is used to pump fresh culture medium in the culture medium storage tank into the culture dish, and then the second pump body is used to pump waste liquid in the culture dish into the recovery tank. However, when the fresh culture medium enters the culture dish through the water pipe, since there is a certain flow rate of the culture medium during the circulation process, when the fresh culture medium enters the culture dish, the flow of the culture medium will generate fluid shear force, which causes the immune cells in the culture dish to change their cell morphology and rupture their cell membranes due to the shear force, thereby affecting the activity and function of the leukocytes in the culture dish that are subjected to the shear force. Summary of the invention

[0004] The purpose of the present invention is to provide an immune cell culture perfusion device to solve the problems mentioned in the above process.

[0007] As a preferred embodiment of the immune cell culture perfusion device of the present invention, the drainage component further comprises a culture plate, a culture tank disposed on the culture plate, and a discharge port disposed in the culture tank.

[0008] As a preferred solution of the immune cell culture perfusion device of the present invention, the lifting component includes a fixed seat, a swing rod arranged on the fixed seat, and a moving rod arranged on the swing rod.

[0010] As a preferred embodiment of the immune cell culture perfusion device of the present invention, it comprises: a driving plate arranged on the base, a driving block arranged on the driving plate, a piston cylinder arranged on the base, a movable plug arranged in the base, and a plug block arranged in the base.

[0011] As a preferred embodiment of the immune cell culture perfusion device of the present invention, the device comprises: an opening and closing plate disposed in the base, an opening and closing rod disposed on the opening and closing plate, and a contact plate disposed on the opening and closing rod.

[0012] As a preferred embodiment of the immune cell culture perfusion device of the present invention, the protective component includes a shell, a mounting ring arranged in the shell, and a hinge arranged on the mounting ring.

[0013] As a preferred embodiment of the immune cell culture perfusion device of the present invention, it comprises: a storage groove arranged on the hinge, a storage plate arranged on the hinge, a first push rod arranged in the storage plate, and a second push rod arranged in the hinge.

[0014] As a preferred solution of the immune cell culture perfusion device of the present invention, wherein: a rotating ring is arranged in the shell, a pull rod is arranged on the rotating ring, a guide rod is arranged on the rotating ring, and a guide plate is arranged on the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The fresh culture medium is atomized by the atomizer and passed into the culture tank, increasing the surface area of ​​the culture medium added to the culture tank, thereby improving the contact efficiency between the immune cells in the culture tank and the culture medium, and promoting the absorption effect of the nutrients in the culture medium by the immune cells. At the same time, the capture rod and the support rod provide attachment points for the mist particles in the atomization tank, so that the mist particles condense into liquid and continue to drip into the culture tank, thereby avoiding the flow of liquid culture medium during the perfusion of the culture medium to generate shear force and act on the immune cells, causing immune cell damage, loss of activity and function, providing a stable and suitable growth environment for the immune cells, and improving the proliferation and differentiation of the immune cells in the culture tank; 2. By setting a baffle at the notch of the atomizer slot, the high-speed mist particles ejected by the atomizer are intercepted, thereby preventing the high-speed mist particles from penetrating the cell membrane of immune cells, causing the immune cells to lose activity and function; 3. The drain port is initially blocked by a fixed ring. When the culture medium in the culture tank accumulates to a certain mass, the spring is deformed, causing the culture plate to move downward. At this time, the fixed ring no longer blocks the drain port, so that the culture medium mixed with cell metabolic waste in the culture tank is discharged through the drain port and collected in the recovery tank. At this time, the immune cells in the culture tank are suspended on the upper liquid surface of the culture medium, so that the fresh culture medium can first contact with the immune cells in the culture tank and then be discharged through the drain port, thereby optimizing the growth environment of the cells. 4. The guide rod slides along the spiral groove, so that the rotating plate drives multiple hinges to move away from or approach each other, thereby blocking the opening and closing grooves. When the atomizer tank rises, the hinges block the opening and closing grooves, thereby preventing the culture medium discharged from the atomizer tank from falling at a higher position relative to the culture plate, thereby hitting the immune cells in the culture tank and causing cell membrane damage; 5. The lifting component makes it easier to take and put the culture plate. When the culture plate is pushed out of the feed trough, the moving plate will contact the contact plate, causing the opening and closing plate to shift, so that the overlapping hole overlaps with the spray port, and the disinfectant in the second air cavity is sprayed out from the spray port, thereby disinfecting and sterilizing the internal environment of the feed trough, providing a good growth environment for the next culture of immune cells.

The atomizing tank 31 is located above the base 11. The atomizer 32 is fixedly installed at the bottom of the atomizer tank 31, the storage tank 33 is connected to the end of the atomizer 32 away from the atomizer tank 31 and is in communication with the inside thereof, the end of the atomizer tank 31 away from the base 11 is provided with a bracket, the bracket is connected to the storage tank 33, and is used to ensure the stability when the storage tank 33 is connected to the atomizer 32. The atomizer 32 preferably adopts an ultrasonic atomizer 32, the ultrasonic atomizer 32 generates high-frequency oscillation through transducer coupling, and generates ultrasonic waves by the chip, the ultrasonic waves use the culture medium as the medium, and then pass through the resonance under the water tank. The emission window atomizes the fresh culture medium in the storage tank 33 into fine mist particles, so that the liquid culture medium is converted into a vapor state to produce an atomization effect. The mist particle emission window of the atomizer 32 is connected to the inside of the atomization tank 31. The baffle 34 is in a continuous S-shaped structure. The baffle 34 is arranged in the atomization tank 31 and is located at the notch position of the atomization groove 311. The end of the atomization tank 31 close to the base 11 is provided with a drip groove array, and the drip box 35 is arranged in the drip groove. The capture rod 36 is arranged in the middle area of ​​the drip box 35 close to the end of the atomization tank 31. A guide groove 1 is arranged in an array on the outer side wall of 36, and the support rod 37 is arranged at the position of the guide groove 1. A guide groove 2 is arranged in an array on a side of the drip box 35 close to the capture rod 36, and the guide groove 2 is communicated with the guide groove 1. A drainage groove is arranged in an array on the drip box 35, and the drainage groove is communicated with the guide groove 2. The drainage plate 38 has a V-shaped structure, and the drainage plate 38 is arranged on a side of the drip box 35 away from the capture rod 36, and the drainage plate 38 is located at the notch position of the drainage groove. A through groove is arranged at the bend of the drainage plate 38, and the drainage needle 39 is arranged in the through groove.

[0031] The drainage component 2 includes a fixed plate 21, a retaining ring 22 arranged on the fixed plate 21, and a movable plate 23 arranged at the lower end of the fixed plate 21. A fixed groove is opened in the fixed plate 21, and the fixed ring is arranged at the notch position of the fixed groove. A mounting ring 52 is arranged at the bottom of the fixed groove. A spring 1 is connected to the bottom of the fixed groove. The spring 1 is located in the mounting ring 52. A drainage groove is arranged in an array on the fixed plate 21. The drainage groove passes through the fixed plate 21 and is communicated with the fixed groove. A collecting groove is opened on a side of the movable plate 23 close to the fixed plate 21. Initially, the drainage grooves are all located at the upper end of the collecting groove, and the collecting groove coincides with the opening end of the collecting tank at this time.

[0032] The drainage component 2 also includes a culture plate 24, a culture trough 25 arranged on the culture plate 24, and a discharge port 26 arranged in the culture trough 25. The culture plate 24 is a disc-shaped structure. The culture plate 24 is slidably arranged in the fixed trough, and the outer diameter of the culture plate 24 and the inner diameter of the fixed ring are adapted to each other. The discharge port 26 is arranged in an array on the side wall of the culture trough 25 away from the end of the trough 25. The end of the spring away from the fixed plate 21 is connected to a side of the culture plate 24 away from the culture trough 25.

[0033] During use, fresh culture medium is first poured into the storage tank 33, and then the storage tank 33 is connected to the start-up nebulizer 32. At this time, the open end of the storage tank 33 is inverted, and the bracket limits and supports the storage tank 33, so as to avoid shaking after the storage tank 33 is connected to the nebulizer 32, resulting in damage to the storage tank 33 and the nebulizer 32 and waste of fresh culture medium. Due to the gravity effect on the fresh culture medium in the storage tank 33, the fresh culture medium in the storage tank 33 will flow from the storage tank 33 to the atomizer 32, and the atomizer 32 will be started at the same time. At this time, the fresh culture medium flowing into the atomizer 32 is converted from liquid to tiny mist particles under the action of the atomizer 32 and enters the atomizer tank 31; Since there are high-speed mist particles in the mist particles entering the atomizing tank 31 from the atomizer 32, after the high-speed mist particles enter the atomizing tank 31, some of the high-speed mist particles will contact with the support rod 37 and the capture rod 36 and adhere to their surfaces, while the other part of the high-speed mist particles will contact with the baffle 34, and the baffle 34 will block the high-speed mist particles so that the high-speed mist particles adhere to the surface of the baffle 34. As the number of fresh culture medium mist particles attached to the surface of the baffle 34 becomes excessive and gradually condenses into liquid culture medium, the liquid culture medium will drip into the culture tank 25 through the atomizing groove 311, and the fresh culture medium mist particles attached to the inner wall of the atomizing tank 31 will also condense into liquid fresh culture medium and enter the culture tank 25 through the atomizing groove 311; As the fresh culture medium atomized into mist particles continues to enter the atomizing tank 31, the concentration of the fresh culture medium mist particles in the atomizing tank 31 continues to increase, thereby increasing the contact probability between the fresh culture medium mist particles in the atomizing tank 31 and the support rod 37, the capturing rod 36, and the baffle 34. Then, the fresh culture medium mist particles attached to the surface of the support rod 37 will gradually condense into droplets. Under the action of gravity, the droplets of fresh culture medium will flow along the guide groove 1 to the guide groove 2. The fresh culture medium mist particles attached to the surface of the capturing rod 36 will also gradually condense into droplets. Under the action of gravity, part of the droplets of fresh culture medium will flow along the guide groove 1 to the guide groove 2, and the other part of the droplets of fresh culture medium will flow along the capturing rod 36 toward the drip box 35, and finally enter the guide groove 2 through the drip box 35. The fresh culture medium condensed from mist into liquid in the second guide groove flows into the drainage groove. As the liquid fresh culture medium is affected by gravity, the liquid fresh culture medium will contact the drainage sheet 38. At this time, the liquid fresh culture medium will flow along the drainage sheet 38 to the through groove position and contact the drainage needle 39. At this time, the condensed fresh culture medium will gradually drip into the culture groove 25 on the culture plate 24 through the drainage needle 39. Among them, the fresh flat culture medium mist particles in the atomizing tank 31 and not in contact with the support rod 37, the capture rod 36, and the baffle 34 will be discharged from the atomizing tank 31 through the atomizing groove 311 and enter the culture tank 25. As the fresh culture medium continuously enters the culture tank 25 from the storage tank 33, the immune cells in the culture tank 25 will absorb the nutrients in the fresh culture medium. Among them, at the beginning, the culture plate 24 will be pushed up to a certain distance from the bottom of the fixed groove under the elastic force of the spring 1, and the discharge port 26 on the culture plate 24 will contact the fixed ring, and the fixed ring will block the discharge port 26. When fresh culture medium continuously enters the culture groove 25, the fresh culture medium in the culture groove 25 will continue to increase, causing the liquid level of the culture medium in the culture groove 25 to gradually rise. At this time, the immune cells in the culture groove 25 will be suspended on the upper surface of the culture medium. At the same time, as the mass of the culture medium in the culture groove 25 continues to increase, the spring 1 is deformed by the gravity of the culture medium in the culture groove 25. At this time, the culture plate 24 moves downward toward the bottom of the fixed groove, so that the discharge port 26 on the culture plate 24 is separated from the fixed ring. At this time, the culture medium below the liquid level of the culture medium in the culture groove 25 will be discharged through the discharge port 26 and enter the fixed groove. Since the fresh culture medium is continuously discharged from the atomizing tank 31 into the culture groove 25, the volume of the culture medium in the culture groove 25 reaches a balanced state, so that the spring 1 is continuously in a deformed state; The culture medium entering the fixed tank enters the collecting tank through the drainage tank, and finally enters the collecting tank from the collecting tank, so that the waste liquid of the culture medium entering the collecting tank is recovered.

When the movable plate 23 drives the fixed plate 21 to move to contact with the contact plate 494, the contact plate 494, the opening and closing rod 493 and the opening and closing plate 492 will move synchronously with the movable plate 23, and the spring sheet 1 will be deformed. At the same time, the overlap hole on the opening and closing plate 492 will overlap with the spraying port. At this time, the disinfectant in the air cavity 2 will pass through the overlap hole and be sprayed out from the spraying port under the action of pressure. At the same time, the push rod 45 has pushed the movable plate 23 and the fixed plate 21 out of the feed chute, and the fixed plate 21 on the movable plate 23 can be removed at this time. When the immune cells need to be cultured again, after the immune cells are placed in the culture tank 25, the fixed plate 21 is placed on the movable plate 23 that has extended out of the feed tank, and then the hydraulic rod is started to shrink the piston end of the hydraulic rod. At this time, the push rod 45 will pull the movable plate 23 and the fixed plate 21, so that the fixed plate 21 is shifted to the reduction tank. At the same time, the spring piece 1 is reset, the overlapping hole and the spray port are misaligned, the atomizing tank 31 is reset, the piston rod is reset, the movable plug 49 is reset, and the plug block 491 is reset. When the plug block 491 does not block the liquid inlet tank, the disinfectant in the disinfection tank will enter the air cavity 2 through the liquid inlet tank.

[0039] The remaining structures are the same as those of Example 1.

[0041] A storage groove 531 is arranged on the hinge 53, a storage plate 54 is arranged on the hinge 53, a push rod 1 55 is arranged in the storage plate 54, and a push rod 2 56 is arranged in the hinge 53. A notch is provided on the hinge 53, the storage plate 54 is hingedly arranged at the position of the notch, and a torsion spring is arranged at the hinge of the storage plate 54 and the notch, a top groove 1 is provided in the storage plate 54, a spring piece 2 is arranged in the top groove 1, one end of the spring piece 2 is connected to the bottom of the top groove 1, and the other end is connected to the push rod 1 55, the push rod 1 55 is slidably arranged in the top groove 1, a top groove 2 is provided in the hinge 53, an elastic groove is provided in the top groove 2, the push rod 2 56 is slidably arranged in the top groove 2, a spring 2 is sleeved on the outside of the push rod 2 56, the spring 2 is arranged in the elastic groove, one end of the spring 2 is connected to the side wall of the elastic groove, and the other end is connected to the push rod 2 56, and the end of the push rod 2 56 away from the notch extends to the outside of the top groove 2.

[0042] A rotating ring 57 is arranged in the shell 51, a pull rod 58 is arranged on the rotating ring 57, a guide rod 571 is arranged on the rotating ring 57, and a guide plate 59 is arranged on the base 11. The rotating ring 57 is rotatably arranged in the shell 51, the pull rod 58 is hingedly arranged on the rotating ring 57, and a plurality of pull rods 58 are arranged in an array on the rotating ring 57, one end of the pull rod 58 away from the rotating ring 57 is hingedly matched with an end of the hinge 53 close to the notch, guide grooves are symmetrically opened on the shell 51, and the guide rod 571 penetrates and is slidably arranged in the guide grooves, and two guide plates 59 are symmetrically arranged on the bottom plate, and a spiral groove is opened on the guide plate 59, and the guide rod 571 is slidably arranged in the spiral groove.

[0043] During use, at the beginning, the storage plate 54 rotates to a position away from the gap under the elastic force of the torsion spring. When the atomizer tank 31 rises, the guide rod 571 will slide along the spiral groove. Under the guidance of the spiral groove, the rotating ring 57 will rotate, causing the multiple hinges 53 to approach each other under the pull of the pull rod 58. In the process of the multiple hinges 53 approaching each other and gradually fitting together, the adjacent hinges 53 will push each other and force the storage plate 54 to rotate to block the gap. When the top rod 1 55 on the storage plate 54 contacts the hinge 53, the spring piece 2 will be deformed, and the top rod 1 55 will shrink into the top groove 1. When the top rod 1 55 moves to overlap with the top groove 2, the top rod 1 55 will extend out and insert into the top groove 2 under the action of the spring piece 2, and the opening and closing groove is blocked at this time. The fresh culture medium discharged from the atomizer tank 31 will be blocked by the multiple hinges 53 and collected in the storage groove 531; When the atomizer tank 31 is in the process of descending, the guide rod 571 will reset along the spiral groove again. At this time, the rotating ring 57 will reset, and the multiple hinges 53 will gradually move away from each other. When the pull rod 58 pulls the hinge 53 to the initial position, the push rod 2 56 will contact the inner wall of the shell 51, and the spring 2 will deform. The push rod 2 56 moves toward the direction of the push rod 1 55, and then the push rod 2 56 will push the push rod 1 55 out of the top groove 2. At this time, since the storage plate 54 is not subject to the pushing force of the adjacent hinge 53, the storage plate 54 will reset under the elastic force of the torsion spring, causing the gap to open at this time, and then the culture medium collected in the storage groove 531 will enter the shell 51 through the gap for collection.
