Description

Technical Field

[0002] Cell genetics refers to the genetic transmission phenomenon of the genetic material inside cells during cell division. Cells are the basic units of organisms and the most basic carriers of genetic information. They contain genetic material DNA inside. Through cell division, genetic information is transmitted to daughter cells, thus ensuring the transmission and stability of genetic information. Cell genetics is an important aspect of biological genetics research and is of great significance for us to understand biological problems such as genetic laws, genetic variation, and evolution. In cell genetic experiments, experimental results need to be obtained through cell culture. During the experiment, an incubator is required to store the culture dishes containing cells, and the incubator provides a suitable growth environment for the cells. It is difficult to control the culture environment of a single culture dish, and there is a lack of comparative observation. For this reason, we propose a cell genetic experiment incubator.

[0038] The specific implementation manner of the present invention is as follows:

[0039] Six culture chambers 5 are arranged inside the frame box body 1 of this device. Each culture chamber 5 is relatively independent, and different culture environments can be set for each culture chamber 5. After turning on the power switch 15, they start running respectively. The touch screen 14 is lit up, and the status light 16 indicates blue (the system is normal and ready to run). The touch screen 14 displays two parts of content. One part is the real-time monitoring video of each culture chamber 5, and the other part is the operating status of each subsystem inside the device. Before the culture experiment, the culture environment is sterilized by the ultraviolet lamp 510. On the touch screen 14, select the initial settings for the control experiment, that is, set the temperature, humidity, carbon dioxide gas concentration, and culture time of each sample culture chamber 5 respectively. It also supports setting culture conditions by stage. The touch screen 14 sends the set parameters to the ECU core controller 10 through the communication line, and uses the ECU core controller 10 to control the operation of each electrical component. By setting a temperature sensor 551, a humidity sensor 552, a carbon dioxide concentration sensor 553, and a pressure sensor 554 in the multi-signal acquisition board 505, the internal environmental parameters of the culture chamber 5 can be monitored in real time. By using multiple pipelines to connect different supply units of variables, the culture environment can be adjusted to ensure the cell culture effect;

[0040] By connecting an external storage device through the USB interface 17, the culture data can be recorded and stored, and a data report of the whole culture process will be automatically generated after the culture is completed. By connecting to an external network through the network cable interface 18, it is convenient to compare the culture data with the cloud database, automatically record the change values and time of each stage. When the set time is reached or the sample is infected, the status light 16 turns red for warning, reminding the operator to analyze and process in time. After the culture is completed, just open the sealed door 6 and take out the culture container. During the culture process, regularly start the corresponding micro pump 514 of the culture chamber, which can introduce the waste liquid in the culture dish 502 along the ceramic ball 512 into the rubber tube 513, and then discharge it out of the frame box body 1 along the path of the waste liquid recovery pipe 511 - waste discharge pipe 515.

The output end of the air pump 105 is connected with an air supply pipe 106. The end of the gas delivery pipe 507 is connected with the air supply pipe 106. The input end of the air pump 105 is connected with two groups of air intake pipes 107. One group of air intake pipes 107 is connected with the carbon dioxide compression gas cylinder 104, and the other group of air intake pipes 107 extends out of the frame box body 1. Solenoid valves are installed in both groups of air intake pipes 107 to facilitate the adjustment of the gas environment.

[0043] Inside the distilled water filling port 3, there is a distilled water tank 301 installed. At the bottom of the distilled water tank 301, there is a piezoelectric ceramic wafer 302 installed. On the rear side wall of the distilled water tank 301, there is a fan 303 embedded. On the front side wall of the distilled water tank 301, there is a humidifying air duct 304 connected. The end of the water mist spraying pipe 504 is connected to the humidifying air duct 304, which is convenient for adjusting the humidity environment.

[0044] Inside the sample collection port 4, there is a sample collection tube 401 inserted. At the upper end of the sample collection tube 401, there is a sampling port cover 402 installed. The end of the sample delivery tube 503 is connected to the sample collection tube 401, which is convenient for sample splitting.

[0045] On the left side of the inner wall of the frame box body 1, there is a main water inlet pipe 111 connected. On the right side of the inner wall of the frame box body 1, there is a main water outlet pipe 112 connected. Inside the main water inlet pipe 111, there is a water pump 113 installed. Between the main water inlet pipe 111 and the main water outlet pipe 112, there is a variable temperature water supply device 114 connected. Both ends of the temperature control pipe 501 are respectively connected to the main water inlet pipe 111 and the main water outlet pipe 112. On the side of the temperature control pipe 501 close to the main water outlet pipe 112, there is a connected check valve 115 installed, which is convenient for ensuring the temperature environment of the culture chamber 5.

[0046] The specific implementation manner of the present invention is as follows:

[0047] In this embodiment, before the culture test, the culture environment is sterilized by the ultraviolet lamp 510. On the touch screen 14, the initial settings of the control test are selected, that is, the temperature, humidity, CO 2 gas concentration, and culture time of each sample culture in the culture chamber 5 are respectively set; it also supports setting multiple stages, and the temperature, humidity, CO 2 gas concentration, and culture time of each stage can be set differently;

[0048] The touch screen 14 sends the set parameters to the ECU core controller 10 through the communication line. Using the ECU core controller 10, first disconnect all the solenoid valves leading to the culture chamber 5, so that the culture chamber 5 forms a closed space. After the air extraction pipe 102 is unblocked, control the vacuum pump 101 to work, and the air in the culture chamber 5 can be evacuated. According to the data fed back by the air pressure sensor 554, the culture chamber 5 is adjusted to the preset negative pressure value; once the preset negative pressure value is reached, disconnect the solenoid valve at the exhaust port of the culture chamber 5 that meets the negative pressure requirement until all the culture chambers 5 reach the preset negative pressure value, and then disconnect all the solenoid valves at the exhaust ports of the culture chambers 5;

[0049] The ECU core controller 10 is used to start an oscillation circuit with an oscillation frequency of about 20KHz, and the output is connected to the piezoelectric ceramic chip 302 placed at the bottom of the distilled water tank 301, thereby converting electrical energy into mechanical vibration with ultrasonic frequency, namely, the diaphragm. The diaphragm acts on the water surface to increase the energy of water molecules and escapes from the water surface to form water mist, which is blown out by the fan 303 and enters the water mist injection pipe 504 from the humidification air duct 304, and then flows into each small culture chamber 5 of the incubator. According to the feedback data of the humidity sensor 552, the corresponding small culture chambers 5 in the incubator are adjusted to the set air humidity value. After the air humidity feedback from the humidity sensor 552 reaches the set value, the solenoid valve of the corresponding small culture chamber 5 channel is closed.

[0050] The temperature control tubes 501 distributed throughout the inner wall of the culture chamber 5 can evenly and stably control the temperature in the culture chamber 5, and because the graphene coating is attached to the inner wall surface, the temperature in the room can be quickly kept stable and uniform. When the room temperature of a small culture chamber 5 of the incubator deviates from the set value, the variable temperature water supply device 114 is used in conjunction with the water pump 113 to provide hot water for exchange, so that the temperature in the corresponding small culture chamber 5 reaches the set temperature, and the corresponding water pump 113 is turned off to keep the temperature consistent, so as to maintain the temperature in each small culture chamber 5 of the incubator consistent with the set temperature;

[0051] The culture sample is placed in the sample collection port 4. After the ECU core controller 10 confirms that the temperature of the culture chamber 5 has reached the set value, it controls the solenoid valve on the sample delivery tube 503 to open. Since each culture chamber 5 is currently in a negative pressure state, the culture sample will be sucked from the sample delivery tube 503 into the culture dish 502, thereby performing cell culture;

[0052] After the culture sample is in place, the ECU core controller 10 can control and adjust the carbon dioxide concentration, that is, start the air pump 105, open the corresponding solenoid valve to allow carbon dioxide or air to enter the gas delivery pipe 507, and then flow into each small culture chamber 5 of the incubator. When the carbon dioxide concentration of a small culture chamber 5 of the incubator reaches the set value, the carbon dioxide concentration feedback from the carbon dioxide concentration detection sensor 553 reaches the set value, and then the air pump 105 and the solenoid valve corresponding to the small culture chamber 5 in the incubator are closed;

[0053] During the sample culture process, each sensor feeds back the real-time environmental parameters in the culture chamber 5 in real time. When the real-time environmental parameters deviate from the set values, the corresponding system is started synchronously to maintain the stability of the culture environment. The conventional parameters that can be set during the culture process are temperature 37°C, CO 2 The concentration was 5%, the pH value was 7.2-7.4, and the relative saturation humidity was 95%. The single parameter was adjusted by comparing the environment, so as to conduct sample monitoring control;

[0054] Turn on the illumination lamp 509 and the electron microscope lens 508. The lens images are transmitted to the touch screen 14 synchronously. Use the stepper motor 581 to adjust the lens for autofocus, which can make the lens images clearer and facilitate subsequent processing and analysis. You can also use the manual adjustment knob 582 to adjust it until the shooting position is accurate.
