[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0028] Embodiment 1:

[0029] like Figure 1-5 As shown, the utility model provides a basic medical experiment multiple bacteria or fungi co-culture culture dish, comprising: a dish body 1, four identical culture tanks 2 are opened on the dish body 1, a transfer tank 3 is opened in the middle of the dish body 1, a connecting hole 4 is opened between the transfer tank 3 and the culture tank 2, each culture tank 2 forms a communicating vessel through the transfer tank 3 and the connecting hole 4, a sealing rod 6 is installed in the transfer tank 3, and a sealing ring 7 is installed on the sealing rod 6. When in use, the dish body 1 is placed on a horizontal operating table so that the dish body 1 is naturally horizontal, and then any one of the culture tanks 2 is moved to the horizontal position. The culture liquid is added to each culture tank 2, and the culture liquid enters the transfer tank 3 through the connecting hole 4, and enters the remaining culture tanks 2 through other connecting holes 4. After standing for a short time, the culture liquid in each culture tank 2 is naturally averaged, and then the sealing rod 6 is used to be inserted into the transfer tank 3, and the sealing ring 7 is blocked in the position of the connecting hole 4. The sealing rod 6 and the inner wall of the transfer tank 3 squeeze the sealing ring 7, thereby sealing the connecting hole 4. The culture tanks 2 are no longer connected. After that, bacterial or fungal culture experiments can be carried out in each culture tank 2.

[0030] By setting up the dish body 1, the culture tank 2, the transfer tank 3, the connecting hole 4, and installing the sealing rod 6 in the transfer tank 3, by utilizing the principle of the communicating vessel, it is possible to conveniently add an equal amount of culture fluid to each culture tank 2, and the sealing rod 6 can be used to interrupt the connection between each culture tank 2, making it more convenient and quick to use.

[0031] Embodiment 2:

[0032] like Figure 1 As shown, a cover 5 is installed on the top of the culture tank 2. When in use, the cover 5 can be placed on the culture tank 2 to separate the inside and outside of the culture tank 2, reduce air circulation inside and outside, and facilitate anaerobic bacterial culture.

[0033] By installing a cover 5 on the top of the culture tank 2, the air circulation inside and outside the culture tank 2 can be blocked, which is conducive to the cultivation of anaerobic bacteria.

[0034] Embodiment 3:

[0035] like Figure 5 As shown, a sealing member 8 made of rubber material adapted to the culture tank 2 is installed at the bottom of the cover 5. When in use, the sealing member 8 at the bottom of the cover 5 is embedded in the top of the culture tank 2 to seal the cover 5 and the culture tank 2.

[0036] By installing a seal 8 at the bottom of the cover 5, it is possible to facilitate sealing between the cover 5 and the culture tank 2.

[0037] Embodiment 4:

[0038] like Figure 5 As shown, a vent hole 9 is provided on the cover 5, a breathable membrane is installed near the bottom of the vent hole 9, a sterilizing agent is coated on the top of the breathable membrane, and a rubber plug 10 is installed in the vent hole 9. When in use, the setting of the breathable membrane facilitates the internal and external circulation of air, and the sterilizing agent is used to kill the bacteria in the air near the vent hole 9 to prevent the bacteria in the air from entering the culture tank 2, and when anaerobic bacteria are cultured, the rubber plug 10 can be inserted into the vent hole 9 to seal the vent hole 9, otherwise the rubber plug 10 can be removed.

[0039] By opening a vent hole 9 on the cover 5, installing a breathable membrane coated with a sterilant in the vent hole, and providing a removable rubber plug 10, the air inside and outside the culture tank 2 can be easily opened and closed according to the culture type.

[0040] Embodiment 5:

[0041] like Figure 5 As shown, a lifting button 11 is installed on the top of the cover 5. When in use, the lifting button 11 can be pinched to conveniently lift or put down the cover 5.

[0042] By installing a lifting button 11 on the top of the cover 5, the cover 5 can be operated conveniently.

[0043] Embodiment 6:

[0044] A rubber gasket is installed at the bottom of the dish body 1. The gasket can be arranged to cover the entire bottom of the dish body 1, or it can be arranged to be evenly installed at the bottom of the dish body 1. When in use, when the dish body 1 is placed on the operating table, the gasket contacts the operating table to cushion the impact or vibration generated during placement, thereby effectively preventing the dish body 1 from breaking.

[0045] By installing a gasket at the bottom of the dish body 1, the safety when placing the dish body 1 can be improved and the possibility of the dish body 1 being broken can be reduced.

[0046] Working principle: When in use, place the dish body 1 on a horizontal operating table so that the dish body 1 is naturally horizontal, and then add culture solution to any culture tank 2. The culture solution enters the transfer tank 3 through the connecting hole 4 and enters the remaining culture tanks 2 through other connecting holes 4. After standing for a short time, the culture solution in each culture tank 2 is naturally evenly distributed. Then use the sealing rod 6 to plug it into the transfer tank 3, and the sealing ring 7 blocks the position of the connecting hole 4. The sealing rod 6 and the inner wall of the transfer tank 3 squeeze the sealing ring 7, thereby sealing the connecting hole 4. The culture tanks 2 are no longer connected. After that, bacterial or fungal culture experiments can be carried out in each culture tank 2.
