As shown in FIG. 11, in the waste box 77, the pipette 23 and the centrifuge tube 22 that are no longer necessary in the culture operation are discarded. The movable range of the first robot 6 and the loading / unloading gloves 40a are disposed. It is provided within the work range.
The disposal box 77 is formed with two disposal spaces 77a and 77b at the front and rear, and disposal bags are set in advance in the disposal spaces 77a and 77b.
Among these, the pipette disposal space 77a on the first robot 6 side is a vertically long space, in which the pipette 23 is discarded, and the centrifuge tube 22 and the dish 21 are disposed in the other container disposal space 77b on the wall surface side of the isolator 2. Those other than the pipette 23 such as are discarded.
As a result, the elongated pipettes 23 can be aligned in the pipette disposal space 77a in the vertical direction, and the volume of waste can be reduced as compared with the case where the pipettes 23 are disposed in the same space as the centrifuge tube 22 and the dish 21. It can be made smaller.

The operation of the liquid supply means 10 having the above configuration will be described.
First, the first robot 6 is equipped with the pipette 23 before the culture operation is performed in the automatic culture operation device 1 in the first to third liquid supply / discharge means 71A to 71C.
First, the pipette 23 carried into the isolator 2 from the pass box 3 is accommodated in the pipette holder 75 with the tip portion facing upward by an operator wearing the carrying-in / out glove 40a.
Then, when the first robot 6 takes out the pipette 23 from the pipette holder 75, the first robot 6 rotates it 180 ° and turns the tip portion downward, and in that state, moves to the first to third liquid supply / discharge means 71A to 71C. Let
At that time, the pipette 23 may be rotated by 90 ° while the pipette 23 is directly transferred between the first robot 6 and the second robot 7.
Referring to FIG. 9, when the pipette 23 is not attached, the elevating means 80 positions the gripper 80a in the lowered position, and in this state, the first robot 6 moves the pipette 23 to the gripper 80a. Hand over.
Then, the elevating means 80 raises the gripper 80a together with the pipette 23, and the upper end portion of the pipette 23 is brought into close contact with the connecting portion 79 from below, whereby the pipette 23 communicates with the supply / discharge means 81, and the pipette 23 It will be held by the two liquid supply / discharge means 71B.
By performing the same operation as this, the pipette 23 is also attached to the first and third dispensing means 71A and 71C.

Next, the operation | movement at the time of dispensing a culture medium to the centrifuge tube 22 using the 1st liquid supply / discharge means 71A is demonstrated. In addition, since the operation | movement at the time of dispensing PBS to the dish 21 using the 2nd liquid supply / discharge means 71B is the same, description is abbreviate | omitted.
First, when the culture medium container 29 is carried into the working chamber 2a from the pass box 3, the level of the culture medium in the culture medium container 29 is registered in the control means 5 in advance.
Specific methods for recognizing the liquid level include a method for recognizing from the weight of the medium container 29 measured by a weight meter as a liquid level detection means, an optical method, an ultrasonic method, a capacitance method, etc. A method of directly measuring the liquid level from the mouth of the culture medium container 29 using a commercially available sensor is conceivable.
Next, a predetermined amount of medium is sucked into the pipette 23 of the first liquid supply / discharge means 71A.
Specifically, the first container holding means 72A moves the culture medium container 29 to the first lid holding means 74A adjacent to the first liquid supply / discharge means 71A, and holds the cover cap 26 by suction.
Further, the first container holding means 72A moves the medium container 29 to the first liquid supply / discharge means 71A, and inserts the pipette 23 into the medium container 29. Then, the supply / discharge means 81 is activated and a predetermined amount of medium is sucked into the pipette 23.
At that time, since the liquid level of the culture medium in the culture medium container 29 is registered in the control means 5, the control means 5 controls the moving means 83 of the first container holding means 72A to The relative height of the medium container 29 with the liquid level of the medium is adjusted.
Specifically, the insertion amount of the pipette 23 inserted into the medium of the medium container 29 is set to a minimum depth, and the first liquid supply / discharge unit 71A sucks the medium of the medium container 29 to obtain the liquid level. When the height decreases, the control means 5 controls the moving means 83 to raise the medium container 29 according to the decrease in the liquid level.
This minimizes the contact area of the medium attached to the outer surface of the pipette 23 and prevents the medium attached to the outer surface of the pipette 23 from falling into the working chamber 2a.
When the culture medium is sucked from the culture medium container 29, the first container holding means 72A moves the culture medium container 29 to the first lid holding means 74A to attach the cover cap 26, and then lowers the culture medium container 29 to the lowered position. Let

When a predetermined amount of medium is sucked into the pipette 23 of the first liquid supply / discharge means 71A in this way, an operation of discharging the medium to, for example, the centrifuge tube 22 held by the second robot 7 is performed.
Specifically, the second robot 7 is activated to take out the centrifuge tube 22 from the centrifuge tube holder 43 and move it to the fourth lid holding means 74D adjacent to the second robot 7 to hold the cover cap 26. .
Then, when the second robot 7 positions the centrifuge tube 22 below the pipette 23 of the first liquid supply / discharge means 71A, the control means 5 controls the supply / discharge means 81 so that the medium contained in the pipette 23 is stored. A predetermined amount is discharged to the centrifuge tube 22.
Even in this case, the control means 5 stores the amount of liquid stored in the centrifuge tube 22, and the second robot 7 determines the relative height between the pipette 23 and the held centrifuge tube 22. It comes to adjust.
When a liquid containing a predetermined amount of cells is stored in the centrifuge tube 22 in advance, the second robot 7 positions the centrifuge tube 22 so that the tip of the pipette 23 is positioned slightly above the liquid level of the liquid. Let
Then, when the medium is discharged from the pipette 23 and the liquid level rises, the second robot 7 lowers the centrifuge tube 22 as the liquid level rises, and the pipette 23 moves the liquid in the centrifuge tube 22 to the liquid. Avoid contact.
When a predetermined amount of medium is dispensed into the centrifuge tube 22 in this way, the second robot 7 moves the centrifuge tube 22 to the fourth lid holding means 74D and attaches the cover cap 26 to the centrifuge tube 22. .

The first liquid supply / discharge means 71A contains the medium stored in the medium container 29 of the first container holding means 72A, and the second liquid supply / discharge means 71B receives the PBS stored in the PBS container 30 of the second container holding means 72B. The third liquid supply / discharge means 71C of the present embodiment handles the trypsin accommodated in the trypsin container 31, and creates a suspension composed of a liquid containing a cell and a medium in the centrifuge tube 22, for example. Also used when doing.
First, when dispensing trypsin, the second robot 7 holds the trypsin container 31 together with the container holder 76, temporarily holds the cover cap 26 in the fourth lid holding means 74D, Trypsin is sucked in the liquid supply / discharge means 71C.
Also at this time, the trypsin liquid level in the trypsin container 31 is registered in the control means 5, so that the trypsin is sucked into the pipette 23 and the liquid surface height is lowered, thereby reducing the trypsin container 31. Is supposed to rise.

In the third liquid supply / discharge means 71C, when the trypsin is dispensed, the used pipette 23 used for the trypsin is replaced with a new pipette 23 when the suspension is prepared. It is supposed to be.
The first robot 6 takes out the empty centrifuge tube 22 supported by the holding member 77 provided in the vicinity of the disposal box 77 in advance, and positions it below the pipette 23 of the third liquid supply / discharge means 71C.
Then, the lifting / lowering means 80 of the third liquid supply / discharge means 71C lowers the pipette 23 to disengage it from the connecting portion 79, and further releases the held pipette 23, whereby the pipette 23 is held by the first robot 6. Drop into the inside of the sunk tube 22.
The first robot 6 accommodates the centrifuge tube 22 containing the pipette 23 in the holding member 77A, whereby the centrifuge tube 22 and the pipette 23 are inclined.
As a result, the pipette 23 is always positioned below the inclined opening of the centrifuge tube 22, and the first robot 6 can reliably hold the pipette 23.
When the first robot 6 removes the pipette 23 from the inclined centrifuge tube 22, the pipette 23 is rotated so that the pipette 23 faces in the vertical direction, and is further positioned above the pipette disposal space 77 a in the disposal box 77. Drop it.
Since the pipette 23 falls while facing the vertical direction, even if the other pipettes 23 are discarded after that, all the pipettes 23 in the pipette disposal space 77a face the vertical direction, and the volume when discarded is reduced. can do.
In this way, after dropping the pipette 23 onto the centrifuge tube 22 held by the first robot 6, the pipette 23 is moved together with the centrifuge tube 22 to the vicinity of the disposal box 77, and then the pipette 23 is discarded into the disposal box 77. By doing so, it is possible to prevent the liquid adhering to the pipette 23 from falling onto the floor 2b of the isolator 2 while moving the pipette 23 to the disposal box 77.
When the used pipette 23 is discarded in this way, the first robot 6 holds a new pipette 23 from the pipette holder 75 and attaches it to the third liquid supply / discharge means 71C.

The inspection means 11 is arranged within the movable range of the second robot 7, and as shown in FIG. 12, the imaging means 11a provided above and below the narrow observation space 11S vertically projecting outward from the back side of the isolator 2, and It is comprised from the illumination means 11b.
The observation space 11S communicates with the work chamber 2a of the isolator 2, and light transmission members such as glass are provided on the upper surface and the lower surface of the observation space 11S. The observation plate 25 held by the second robot 7 is used for the observation. It is inserted into the space 11S.
The imaging means 11a is provided above the observation space 11S, and the illumination means 11b is provided below the observation space 11S. The light of the illumination means 11b is transmitted through the light transmitting member and the plate 25a of the observation plate 25. The imaging means 11a captures an enlarged image of the cells on the plate 25a.
The image taken by the imaging means 11a is image-processed by the control means 5, and for example, the number of surviving cells in the observation range and the number of dead cells are counted, from which the cell survival rate is calculated. It is calculated.
Note that the dish 21 placed on the attachment 33 can be inserted into the observation space 11S, and the occupancy of the cells in the mixture of cells and culture accommodated in the dish 21 can be obtained by image processing.

In the substituting operation described later in the present embodiment, in the liquid supply means 10, the robot holds the culture medium sucked from the culture medium container 29 by the first liquid supply / discharge means 71 A constituting the culture medium supply means. It supplies to the new empty dish 21 as a culture container.
On the other hand, the third liquid supply / discharge means 71C constituting the distribution means sucks the suspension of the cells and the medium from the centrifuge tube 22 as the first culture container, and the plurality of second liquids transferred by the robot are transferred to the suspension. The cells are distributed to a new dish 21 by dispensing into the dish 21 as a culture container.
At this time, in this embodiment, based on the inspection result of the inspection means 11, the amount of culture medium newly required for the current passage work is obtained, and the number of new dishes 21 to be distributed is determined based on this amount. The determination means for performing the determination is provided in the control means 5.
The determination means determines whether or not the survival rate exceeds a predetermined threshold value when the number of viable cells is counted in the inspection means 11, and is used when the threshold value is not exceeded. A standard amount is selected as the amount of the medium, and the above passage operation is performed in a standard passage mode in which cells are passaged to a predetermined number of dishes 21 associated therewith.
On the other hand, when the number of surviving cells exceeds the threshold value in the test result, many cells are alive, so this is more than when subcultured in the standard passage mode. A lot of medium is required.
Therefore, the determination means selects the medium amount larger than the standard, and the passage work in the excellent passage mode in which cells are passaged to a larger number of dishes 21 than the standard passage mode associated therewith. Is supposed to be executed.
For example, when the cells stored in one centrifuge tube 22 in the standard passage mode are passaged to 10 new dishes 21, the cells are passaged to 15 dishes 21 in the excellent passage mode. It is like that.
Since the cell inspection is performed by extracting a part of the cultured cells, the required amount of medium is calculated by multiplying the obtained survival number by a predetermined coefficient. Alternatively, the number of dishes 21 may be obtained by dividing the calculated amount of medium to be distributed by the amount of medium accommodated per dish 21.

Further, the inspection means 11 and the determination means can be used not only to determine the number of dishes 21 to be cultured in the passage work but also to determine whether or not to perform the passage operation.
For example, the second robot 7 takes out the dish 21 from the incubator 4 at a predetermined interval, for example, a predetermined time every morning, and moves the cells along with the dish 21 to the inspection means 11.
Then, the imaging means 11a of the inspection means 11 photographs the cells in the dish 21 and measures the occupation ratio of the cells in the image, and the control means 5 determines that the cells are sufficiently cultured based on the occupation ratio of the cells. If it is determined that the above-mentioned passaging operation is performed, it is determined.

When observing the cells by the observation means 11, trypan blue contained in the reagent container 32 is added to the cells placed on the observation plate 25, so that the number of viable cells can be easily determined by the imaging means 11a. It can be measured.
Therefore, in the working chamber 2a, a reagent supply means 101 for supplying the trypan blue to the observation plate 25, and a micropipette nozzle for the micropipette 34 used for supplying the cells and trypan blue to the observation plate 25 are provided.

FIG. 19 shows a flow of subculture work. At this time, a dish 21 containing cells is accommodated in the incubator 4 connected to the isolator 2, and the isolator 2 contains the dish 21, centrifuge tube 22, instrument and the like. A pipette 23 and an aspirator nozzle 24 are carried in as a kind, and a medium container 29, a trypsin container 31 and a reagent container 32 are carried in as liquids.
First, the work of carrying out the dish 21 in the incubator 4 (C-1) and the work of removing the medium older than the dish 21 (C-2) are performed. Since the operation is the same as that of -2, detailed description is omitted.
The dish 21 from which the medium has been removed is placed on the delivery table 42 together with the attachment 33.

Next, an operation of dispensing trypsin to the dish 21 is performed (C-3).
First, the second robot 7 takes out the trypsin container 31 together with the container holder 76, moves it to the second liquid supply / discharge means 71 </ b> B, and sucks trypsin into the pipette 23. Since PBS is not used in this passage work, trypsin can be sucked into the second liquid supply / discharge means 71B in this work.
Thereafter, the first robot 6 holds the dish 21 on the delivery table 42 and moves it to the second liquid supply / discharge means 71B, and the second liquid supply / discharge means 71B discharges the trypsin of the pipette 23 to the dish 21. To do.
Then, the first robot 6 stores the dish 21 into which trypsin has been dispensed together with the attachment 33 in the heating chamber 44, and the heating chamber 44 heats the dish 21 to a predetermined temperature.

Next, an operation of consolidating the suspension of cells and trypsin into one centrifuge tube 22 is performed (C-4).
First, the second robot 7 takes out the dish 21 heated to a predetermined temperature from the heating chamber 44. At that time, the second robot 7 moves the dish 21 to the tapping means 46 of the heating chamber 44, and the tapping means 46 vibrates the dish 21 to peel off the cells attached to the bottom of the dish 21.
Subsequently, the second robot 7 moves the dish 21 to the third liquid supply / discharge means 71C, and repeatedly sucks and discharges the cells and trypsin in the dish 21 with the pipette 23 to create a suspension. Is sucked into the pipette 23.
Then, the second robot 7 delivers the empty dish 21 to the first robot 6 and discards it in the disposal box 77.
On the other hand, the first robot 6 holds the empty centrifuge tube 22 from the rotary stocker 8, moves it to the third liquid supply / discharge means 71 </ b> C, and discharges the suspension from the pipette 23 to the centrifuge tube 22.
The second robot 7 repeats the above operation on the dish 21 stored in the heating chamber 44, and the centrifuge tube 22 that holds the suspensions stored in the plurality of dishes 21 by the first robot 6. To aggregate.
When a predetermined amount of suspension is stored in the centrifuge tube 22, the first robot 6 supports the centrifuge tube 22 on the centrifuge tube holder 43.

Subsequently, the operation of centrifuging the suspension in the centrifuge tube 22 (C-5), the operation of inspecting the cells (C-6), and the suspension with the medium are prepared and divided into the dish 21. Work to be poured (C-7) and work (C-8) for bringing the dish 21 into the incubator 4 are performed.
These operations are the same as A-3 to A-6 in the seeding operation, but in the operation of examining the cells according to C-6, the determination unit provided in the control unit 5 is suspended. The number of dishes 21 to which the liquid is distributed is determined.
Specifically, in the inspection work relating to the above C-6, the number of viable cells on the observation plate 25 is measured in the inspection means 11, and the amount of newly required medium is obtained based on the number of viable cells. Based on this, it is determined whether the operation of C-7 is performed in the normal passage mode or the excellent passage mode.

When the determination means determines that the C-7 dispensing operation is to be performed in the normal passage mode, the control means 5 removes the suspension containing the cells concentrated in one centrifuge tube 22 as the first culture vessel. For example, the first and second robots 6 and 7 and the liquid supply means 10 are controlled so as to dispense into the dish 21 as ten second culture vessels.
At this time, the control means 5 controls the first liquid supply / discharge means 71A and the first container holding means 72A, and the pipette 23 of the first liquid supply / discharge means 71A has the medium dispensed into the ten dishes 21. The total amount of is aspirated.
On the other hand, when the determination means determines that the C-7 dispensing operation is performed in the excellent passage mode, the control means 5 distributes the suspension containing the cells contained in the centrifuge tube 22 into, for example, 15 dishes 21. Let me note.
Also in this case, the control means 5 controls the first liquid supply / discharge means 71A and the first container holding means 72A, so that the medium to be dispensed into the fifteen dishes 21 is dispensed to the pipette 23 of the first liquid supply / discharge means 71A. The total amount is aspirated. If the entire amount of medium cannot be aspirated at a time, aspiration and discharge can be performed in multiple batches, and the same operation as the number of dishes 21 can be performed for each dish 21. You may make it control the said 1st, 2nd robots 6 and 7 and the liquid supply means 10 so that it may repeat.
The newly required amount of the medium can be obtained by multiplying the measured number of survival by a predetermined coefficient, and the dish to be distributed from the amount of the medium to be accommodated in one dish 21 with respect to the obtained amount of medium. The number 21 may be obtained.

In this way, in the subculture work, in order to distribute cells to more dishes 21 than the number of dishes 21 taken out from the incubator 4, in the work of carrying the dishes 21 into the incubator 4 according to C-8, When all the dishes 21 cannot be accommodated in the incubator 4, the dishes 21 are accommodated in the other incubators 4.
At that time, when all the dishes 21 cannot be accommodated in the two incubators 4 connected to the isolator 2 at the start of the culture operation, the second incubator 4 is completely accommodated in the first incubator 4. While the incubator 4 and the work chamber 2a are in communication, the decontamination space S of the connecting means 111 of the incubator 4 is immediately decontaminated and detached, and the third incubator 4 is connected.
Then, while carrying in the dish 21 while the second incubator 4 can communicate with the work chamber 2a, the decontamination space S is decontaminated by the connecting means 111 of the third incubator 4. The dish 21 can be carried in by allowing the third incubator 4 to communicate with the work chamber 2a.
At this time, as described above, since the connecting means 111 of the present embodiment only needs to decontaminate a narrow decontamination space, the first incubator 4 can be quickly detached and the third unit connected. It is possible to perform the subculture work efficiently.
Further, by performing decontamination when the incubator 4 is detached, it is possible to prevent the virus specific to the specimen from leaking from the work chamber 2a to the outside. It prevents bacteria and microorganisms from being brought into the work chamber 2a.

FIG. 20 shows a flow of recovery work.
