[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] It should be noted that in the description of this utility model, terms such as "left" and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Specifically, this utility model provides a cell culture workstation, such as Figures 1 to 4 As shown, the cell culture workstation of this utility model includes a box 1, a first liquid storage component 20, a culture vessel 3, and a liquid supply component.

[0032] The housing 1 has a cold storage chamber 11 and a culture chamber 12. The first liquid storage component 20 is located in the cold storage chamber 11 and is used to store culture medium. The culture vessel 3 is located in the culture chamber 12 and can store and culture cells. The first liquid storage component 20 and the culture vessel 3 are connected by a liquid supply component, which is used to transport the culture medium in the first liquid storage component 20 to the culture vessel 3.

[0033] The refrigerator compartment 11 has a refrigerator door 16, which can close the refrigerator compartment 11. For example, the top of the refrigerator door 16 is pivotally connected to the box body 1, and the refrigerator door 16 can be rotated upward to open. The culture chamber 12 has a culture chamber door 15, which can close the culture chamber 12. For example, the left end of the culture chamber door 15 is pivotally connected to the box body 1, and the culture chamber door 15 can be rotated to the left to open.

[0034] For example, the cold storage chamber 11 is located near the top of the cabinet 1. The temperature of the cold storage chamber 11 is generally maintained at 2°C to 8°C for the cold storage of the culture medium. The culture medium is stored in the first liquid storage component 20, which is preferably a liquid storage bag. In order to maintain the temperature of the cold storage chamber 11 at the set temperature, a refrigeration device (not shown in the figure) is also provided in the cabinet 1 to regulate the temperature of the cold storage chamber 11. The culture chamber 12 is located below the cold storage chamber 11 and is used to provide the environment required for cell growth. The cells to be cultured are specifically located in the culture vessel 3, which is placed in the culture chamber 12. During the cell culture process, the culture medium is delivered to the culture vessel 3 through the liquid supply component for cell growth.

[0035] It should be noted that this utility model does not limit the specific type of refrigeration device. For example, a refrigeration device similar to that in an air conditioner can be used, or a semiconductor refrigeration device can be used.

[0036] Furthermore, it should be noted that the first liquid storage component 20 is not limited to the aforementioned liquid storage bag. For example, it can also be configured as a liquid storage bottle or liquid storage container. Such adjustments and changes to the specific type of the first liquid storage component 20 do not deviate from the principle and scope of this utility model and should all be limited to the protection scope of this utility model. Of course, this utility model preferably configures the first liquid storage component 20 as a liquid storage bag.

[0037] Furthermore, it should be noted that this utility model does not limit the specific structural form of the culture vessel 3. Those skilled in the art can use any form of culture vessel in the prior art in practical applications, as long as it can achieve cell culture.

[0038] Preferably, such as Figure 1 and Figure 6 As shown, the culture device 3 of this invention includes a shell and a plurality of hollow fiber tubes (not shown in the figure) installed inside the shell. The interior of the hollow fiber tubes forms channels for the flow of culture medium, and the cells are attached to the outer wall of the hollow fiber tubes.

[0039] The culture device 3 used in this invention is a hollow fiber culture device, which is a commonly used culture device in the prior art. For example, the outer shell of the culture device 3 is cylindrical, and the left end face and the right end face of the outer shell are respectively provided with an inlet 31 and an outlet 32. After the culture medium enters through the inlet 31, it flows into the hollow fiber tube and then slowly flows along the hollow fiber tube toward the outlet 32. The nutrients in the culture medium can pass through the tube wall of the hollow fiber tube and permeate to the outside of the hollow fiber tube for cell absorption.

[0040] Preferably, such as Figure 3 and Figure 4As shown, the cell culture workstation of this utility model also includes an electrical control component installed inside the housing 1. The housing 1 is provided with an inspection port 10 at a position corresponding to the electrical control component. The electrical control component includes a mounting base 91 and a plurality of electrical control elements 92 installed on the mounting base 91. The top end of the mounting base 91 is pivotally connected to the housing 1 so that the mounting base 91 can rotate upward. A limiting member 93 is provided on the housing 1, which can stop the mounting base 91 at the current position after rotation.

[0041] By pivotally connecting the top of the mounting base 91 to the housing 1, when maintenance is required on the electrical control component 92 on the mounting base 91, the maintenance personnel can rotate the mounting base 91 upwards by a certain angle, and then fix the mounting base 91 by the limiting member 93, so that the mounting base 91 stays in the current position. Compared with the vertical mounting base 91, the mounting base 91 is in an inclined state, which makes it easier for maintenance personnel to maintain the electrical control component 92 on the mounting base 91. In addition, by rotating the mounting base 91, a part of the electrical control component 92 can also pass through the access port 10 and be located outside the housing 1, which is even more convenient for maintenance.

[0042] The electronic control assembly includes multiple electronic control elements 92, among which a control board is used to control the refrigeration device and the liquid supply assembly. Exemplarily, the multiple electronic control elements 92 include a main control board 921, a refrigeration control board 922, a valve control board 923, a switching power supply 924, and a filter 925, etc., wherein the refrigeration control board 922 is a control board used to control the refrigeration device described above, and the main control board 921 and the valve control board 923 are control boards capable of controlling the liquid supply assembly described above.

[0043] It should be noted that the present invention does not limit the specific location of the access port 10. For example, it can be set on the back or side of the housing 1. Of course, it is preferred to set the access port 10 on the back of the housing 1.

[0044] Furthermore, it should be noted that this utility model does not limit the specific structural form of the mounting base 91. For example, the mounting base 91 can be set as a mounting plate or a mounting bracket, etc. Of course, this utility model preferably sets the mounting base 91 as a mounting plate.

[0045] Furthermore, it should be noted that this utility model does not limit the specific structural form of the limiting member 93. For example, the limiting member 93 can be set as a hook or a support rod, etc.

[0046] Preferably, such as Figure 4As shown, the limiting component 93 is a hook, and the mounting base 91 is provided with a structure that cooperates with the hook. After rotating the mounting base 91 by a certain angle, the hook can hook the mounting base 91 and fix the mounting base 91 in the current position.

[0047] It should be noted that, in practical applications, those skilled in the art can set hanging holes and hooks to cooperate on the mounting base 91, or set hanging rings and hooks to cooperate, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

[0048] Preferably, such as Figure 3 and Figure 4 As shown, the electrical control component of this utility model also includes a handle 911 disposed on the mounting base 91. By providing a handle 911 on the mounting base 91, maintenance personnel can hold the handle 911 and lift it upwards to easily rotate the mounting base 91, making operation more convenient.

[0049] For example, a handle 911 is provided on the left and right sides near the bottom of the mounting base 91. The handle 911 is approximately U-shaped. Two hooks are provided on the housing 1, spaced apart from each other. After the maintenance personnel rotate the mounting base 91 upwards by a certain angle, the two hooks can hook the corresponding handle 911 respectively, so that the mounting base 91 stays in the current position.

[0050] Preferably, such as Figure 1 , Figure 2 and Figure 5 As shown, the liquid supply assembly of this utility model includes a first liquid supply assembly and a second liquid supply assembly. The second liquid supply assembly includes a second liquid storage component 24, a circulation pipe 25, and a circulation pump 26. The first liquid supply assembly is connected to the first liquid storage component 20 and the second liquid storage component 24. The circulation pump 26 is connected to the second liquid storage component 24 and the culture vessel 3 through the circulation pipe 25. The circulation pump 26 is used to circulate the culture medium between the second liquid storage component 24 and the culture vessel 3.

[0051] During cell culture, the culture medium in the first liquid storage component 20 is first transported to the second liquid storage component 24 through the first liquid supply component, and then the culture medium is circulated between the second liquid storage component 24 and the culture vessel 3 by the circulation pump 26.

[0052] For example, the inlet of the circulation pump 26 is connected to the second liquid storage component 24 through a circulation pipe 25, and the outlet of the circulation pump 26 is connected to the inlet 31 of the culture vessel 3 through another circulation pipe 25. The outlet 32 ​​of the culture vessel 3 is then connected to the second liquid storage component 24 through another circulation pipe 25, forming a culture medium circulation loop. Preferably, the circulation pump 26 is a peristaltic pump, and the circulation pump 26 can be controlled by the main control board 921 of the electronic control component.

[0053] Preferably, such as Figure 1 , Figure 2 and Figure 5 As shown, the first liquid supply assembly of this utility model includes a liquid supply pipe 21, a liquid supply pump 22, and a liquid supply control valve 23. The liquid supply pump 22 is connected to the first liquid storage component 20 and the second liquid storage component 24 through the liquid supply pipe 21. The liquid supply pump 22 can pump the culture medium in the first liquid storage component 20 to the second liquid storage component 24. The liquid supply control valve 23 is used to control the opening and closing of the liquid supply pipe 21.

[0054] For example, the inlet end of the liquid supply pump 22 is connected to the first liquid storage component 20 through a liquid supply pipe 21, and the outlet end of the liquid supply pump 22 is connected to the second liquid storage component 24 through another liquid supply pipe 21. The liquid supply control valve 23 is disposed on the liquid supply pipe 21 between the inlet end of the liquid supply pump 22 and the first liquid storage component 20. Preferably, the liquid supply pump 22 is a peristaltic pump, the liquid supply pipe 21 is preferably a flexible hose, and the liquid supply control valve 23 is preferably a pinch valve. The liquid supply pump 22 can be controlled by the main control board 921 of the electronic control component, and the liquid supply control valve 23 can be controlled by the valve control board 923 of the electronic control component.

[0055] Preferably, such as Figure 1 , Figure 2 and Figure 5 As shown, the second liquid supply assembly of this utility model also includes a circulation control valve 27, which is used to control the opening and closing of the circulation pipe 25.

[0056] For example, the circulation pipe 25 has three sections, located between the inlet end of the circulation pump 26 and the second liquid storage component 24, between the outlet end of the circulation pump 26 and the inlet 31 of the culture vessel 3, and between the outlet 32 ​​of the culture vessel 3 and the second liquid storage component 24, respectively. The circulation control valve 27 can be installed on any one of the three sections of the circulation pipe 25. Preferably, the circulation pipe 25 is a flexible hose, and the circulation control valve 27 is preferably a pinch valve. The circulation control valve 27 can be controlled by the valve control board 923 of the electronic control assembly.

[0057] Preferably, such as Figure 1 , Figure 2 and Figure 5As shown, the liquid supply pump 22 and liquid supply control valve 23 of the first liquid supply component and the circulation pump 26 and circulation control valve 27 of the second liquid supply component are all installed on the back plate 122 of the culture chamber 12. The back plate 122 is detachably and fixedly connected to the main shell 121 of the culture chamber 12.

[0058] By mounting the liquid supply pump 22, liquid supply control valve 23, circulation pump 26, and circulation control valve 27 all on the back plate 122 of the culture chamber 12, it is easy to replace them as a whole according to different culture programs. Specifically, there are many different culture programs for cell culture, and different culture programs directly affect the number and layout of control valves and pumps. By integrating all the control valves and pumps required for cell culture onto the back plate 122 of the culture chamber 12, when a different culture program needs to be changed, the back plate 122 can be directly removed for complete replacement.

[0059] Preferably, such as Figure 1 As shown, a plurality of first liquid storage components 20 are provided in the cold storage compartment 11. Each first liquid storage component 20 is connected to a liquid supply pipe 21 (referred to as a branch liquid supply pipe), and each branch liquid supply pipe is provided with a corresponding liquid supply control valve 23. The plurality of branch liquid supply pipes are all connected to the same liquid supply pipe 21 (referred to as the main liquid supply pipe), and the main liquid supply pipe is connected to the liquid inlet end of the liquid supply pump 22.

[0060] In other words, the first liquid supply assembly includes multiple liquid supply control valves 23 and multiple liquid supply pipes 21. The multiple liquid supply pipes 21 are respectively connected to the corresponding first liquid storage component 20. The multiple liquid supply control valves 23 are respectively used to control the opening and closing of the corresponding liquid supply pipes 21. The multiple liquid supply control valves 23 are all installed on the back plate 122 of the culture chamber 12.

[0061] For example, five first liquid storage components 20 are provided in the cold storage compartment 11, and there are also five liquid supply control valves 23, each corresponding to one first liquid storage component 20. The five liquid supply control valves 23 are normally in the off state. When the culture medium in a certain first liquid storage component 20 needs to be used, the corresponding liquid supply control valve 23 is turned on to start the liquid supply.

[0062] Preferably, such as Figure 5 As shown, the second liquid supply assembly of this utility model also includes a heater 28, which is used to heat the culture medium in the second liquid storage component 24.

[0063] Since the first liquid storage component 20 is located in the cold storage chamber 11, the temperature of the culture medium is relatively low. The culture medium in the first liquid storage component 20 is first transported to the second liquid storage component 24 through the first liquid supply component. After the culture medium in the second liquid storage component 24 is heated by the heater 28, the culture medium is then allowed to enter the incubator 3.

[0064] It should be noted that this utility model does not limit the specific structural form of the heater 28. For example, it can be set as a heating wire, heating plate or heating tube, etc. Such adjustments and changes to the specific structural form of the heater 28 do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0065] Preferably, such as Figure 5 As shown, the heater 28 of this utility model includes an annular heating element 281, which is arranged around the second liquid storage component 24.

[0066] By using an annular heating element 281 to heat the culture medium in the second liquid storage component 24, the temperature of the culture medium can be made more uniform. For example, the second liquid storage component 24 is a liquid storage bottle, and the annular heating element 281 forms a cylindrical structure in which the liquid storage bottle is inserted.

[0067] Preferably, such as Figure 5 As shown, the heater 28 of this utility model also includes a horizontal heating element 282. The bottom end of the annular heating element 281 is fixedly connected to or integrally formed with the horizontal heating element 282. The annular heating element 281 and the horizontal heating element 282 together form a heating cavity, and the second liquid storage component 24 is located in the heating cavity.

[0068] The annular heating element 281 is vertically arranged to form the side wall of the heating chamber, and the horizontal heating element 282 is horizontally arranged to form the bottom wall of the heating chamber. The horizontal heating element 282 supports the bottom of the second liquid storage component 24.

[0069] Preferably, such as Figure 5 As shown, the heater 28 of this invention also includes an annular fixing plate 283. The top end of the annular heating element 281 is fixedly connected to or integrally formed with the annular fixing plate 283. The bottom plate 123 of the culture chamber 12 is provided with an installation opening. The size of the installation opening is larger than the outer diameter of the annular heating element 281 and smaller than the outer diameter of the annular fixing plate 283. The annular heating element 281 and the horizontal heating element 282 pass through the installation opening, and the annular fixing plate 283 abuts against the upper surface of the bottom plate 123. That is to say, the annular heating element 281 and the horizontal heating element 282 are located below the bottom plate 123, and the annular fixing plate 283 is located above the bottom plate 123, which is equivalent to hanging the heater 28 on the bottom plate 123.

[0085] Preferably, such as Figures 7 to 9 As shown, a first limiting groove 623 is provided on the first hook post 622, and the first hanging hole on the liquid storage bag is located in the first limiting groove 623. By providing the first limiting groove 623 on the first hook post 622, after the liquid storage bag is installed on the first hook post 622, the first hanging hole is located at the first limiting groove 623, which can prevent the liquid storage bag from separating from the first hook post 622, thereby preventing the liquid storage bag from falling off.

[0086] Preferably, such as Figures 7 to 9 As shown, the insertion end of the first hook post 622 is provided with a first tapered portion 624. By providing the first tapered portion 624 at the insertion end of the first hook post 622, the first hook post 622 can more easily pass through the first hook hole on the liquid storage bag when installing the liquid storage bag.

By providing the second conical portion 634 at the insertion end of the second hook post 632, the second hook post 632 can more easily pass through the second hook hole on the liquid storage bag when installing the liquid storage bag.

[0091] It should be noted that regarding the formation of the first limiting groove 623 and the second limiting groove 633 mentioned above, a portion of the middle part of the hanging post can be removed to form a groove, thus reducing the diameter of the middle part of the hanging post to form a limiting groove. Alternatively, the hanging post can be configured to consist of three parts, with the diameter of the middle part being smaller than the diameters of the two side parts, so as to form a limiting groove in the middle part of the hanging post, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should all be limited to the protection scope of this utility model.

The detection mechanism 41 is used to detect the indicators of the culture medium. The multiple electronic control elements 92 of the electronic control assembly also include a control board for controlling the liquid extraction assembly.

[0093] For example, the indicator of the culture medium is glucose concentration. As the cells grow, the glucose concentration in the culture medium will gradually decrease. The glucose concentration in the culture medium is detected by the detection device 41. When the glucose concentration is lower than the lower limit, the culture medium is replaced in time.

[0094] It should be noted that the indicators of the culture medium are not limited to the glucose concentration mentioned above. In practical applications, those skilled in the art can determine the specific content of the culture medium indicators according to the specific cell type.

The multiple electrical control elements 92 of the electrical control assembly also include a control board for controlling the drive device.

[0115] It should be noted that in practical applications, it is not necessary to drive the incubator 3 to rotate a full circle. Instead, the drive device should drive the incubator 3 to rotate back and forth, for example, first rotating it forward at a certain angle and then rotating it in the opposite direction.
