Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a light incubator. Background Art

[0002] Most of the illumination incubators currently on the market are modified from ordinary cell culture incubators. The modification method is generally to install lamps inside the incubator, or to open holes above the inner cavity of the incubator and fix the lamps on the upper surface of the cavity. The incubators produced by these modification methods have many problems, such as: the waste heat generated by the light source affects the uniformity of the ambient temperature of the inner cavity of the incubator, causing the inner cavity to have a certain temperature difference; the top-down illumination method of the light source easily causes condensation on the culture dish or the upper surface of the inner cavity, which in turn easily causes water droplets to form on the cavity wall; and the uniformity of illumination is reduced due to condensation. These problems will cause the environmental factors (temperature, humidity, and light) of multiple parallel samples in the cavity to decrease in accuracy when using such illumination incubators for cell experiments, that is, the parameter accuracy of the illumination incubator decreases, which in turn leads to an increase in the error of the experimental results of parallel samples, which is not conducive to the cultivation of cells, microorganisms, etc.

[0003] In addition, for microorganism and cell culture using inverted culture dishes, whether the light source is fixed on the top or the side, it cannot meet the culture conditions of this type of culture receiving light from the bottom up, so it is necessary to use a new lighting method for this type of demand.

[0029] like Figures 1 to 4 As shown, the present embodiment provides a light incubator, including a light module 10, an interactive control module 20, an inner cavity environment control module 30, an inner cavity 40 and a housing 50. The interactive control module 20 is used to display the working status of the light incubator and allow the user to set the working parameters of the light incubator, including: light parameters, temperature, carbon dioxide concentration and other parameters. The light module 10 is used to provide light of the set light parameters to the inner cavity 40. The inner cavity environment control module 30 is used to control the temperature and carbon dioxide concentration of the inner cavity 40 so that the inner cavity 40 is at the set values ​​of the temperature and carbon dioxide concentration in the working parameters. The inner cavity 40 is used to place a cell plate or a culture dish, the cell plate is used to place cells for experiments, and the culture dish is used to place microorganisms and culture media for experiments. The housing 50 is an upper opening door, which is used to enclose the light module 10, the inner cavity environment control module 30 and the inner cavity 40. The interactive control module 20 is arranged on the housing 50.

[0030] The illumination module 10 is composed of an LED light board group 11, a driving board 12, a lifting platform 13, a heat dissipation system 14 and a drawer 15. The LED light board group 11 is used to illuminate the inner cavity 40. The normal line of the light-emitting surface of the LED light board group 11 coincides with the normal line of the opening on the lower surface of the cavity of the inner cavity 40. The driving board 12 is used to provide current and voltage to the LED light board group 11. The lifting platform 13 is used to lift or lower the LED light board group 11 and the heat dissipation system 14 so that the light-emitting surface of the LED light board group 11 is close to the glass inlaid with the opening on the lower surface of the cavity of the inner cavity 40. The drawer 15 is used to encapsulate the LED light board group 11, the driving board 12, the lifting platform 13 and the heat dissipation system 14. The drawer 15 is located below the inner cavity 40. The drawer 15 can be moved along the slide rail to be pulled out or inserted into the illumination incubator. There is an adjustment rod 16 for adjusting the lifting platform 13 next to the handle of the drawer 15. When the drawer 15 is inserted into the light incubator, the lifting platform 13 is raised or lowered by moving the rod head of the adjusting rod 16 up and down. The LED light board group 11, the driving board 12 and the heat dissipation system 14 are connected to each other through cables.

[0031] The LED light board group 11 is composed of multiple light boards, for example, up to 8 light boards that can be controlled independently. The light board has one or more LED particles. The LED particles have lighting parameters, including lighting frequency, duty cycle and peak current. The light boards are isolated by gaskets to prevent light leakage. A heat sink is attached to the back of the LED light board group 11, opposite to the heat dissipation system 14. The heat dissipation system 14 can be, for example, a cooling fan, for example, it can be opened at the bottom of the drawer 15 and the box body 50, and hot air can be blown out to dissipate heat. Preferably, the illumination module 10 and the inner cavity environment control module 30 are separated in the box body 50 to prevent the heat dissipated by the illumination module 10 from affecting the cooling or heating of the inner cavity environment control module 30.

[0032] The driver board 12 is modular and the data of the module is adjustable. A single module can output up to 8 drives to control the lighting parameters respectively. The driver board 12 is connected to the LED light board group 11 and the touch screen to transmit and receive signals of the working parameters.

The upper surface of the inner cavity body 41 is opened on the entire surface, and the glass sealing door 43 is fixed. A plurality of vents 45 are opened on the right surface of the inner cavity body 41 to introduce the wind blown in by the circulating fan 36. The partition 42 can move up and down to adjust the height of the cell plate or the culture dish. For example, different blocks can be provided on the inner side of the cavity 41, and the partition 42 can be stuck on different blocks to achieve height adjustment, or other structures can be used to achieve up and down adjustment. The partition 42 is only light-transmissive at the opening, and the rest of the parts are completely shielded. The opening corresponds to the multiple holes of the inner cavity body one by one. A vent 46 is opened on the right surface of the inner cavity body 41 to introduce carbon dioxide from the carbon dioxide pump 35. A light-transmitting hole 47 is opened on the right surface of the inner cavity body 41 to insert the sensor 31. An ultraviolet sterilization lamp can be installed on the inner wall of the inner cavity 41, and the lamp is connected to the controller 32 or the touch screen.

[0036] The sensor 31 includes a temperature sensor and a carbon dioxide concentration sensor. The sensor 31 is used to collect information such as the ambient temperature and carbon dioxide of the inner cavity 40 and transmit it to the controller 32. The sensor 31 is placed in the box 50 and extends into the inner cavity 40.

[0037] The controller 32 can adjust the working states of the compressor 33, the heater 34 and the carbon dioxide pump 35 according to the ambient temperature and carbon dioxide of the inner cavity 40 and the set values ​​of the working parameters, so that the internal environment of the inner cavity U4 meets the set values ​​of the working parameters.

[0038] The carbon dioxide pump 35 is used to change the carbon dioxide concentration in the inner cavity U4. The carbon dioxide pump 35 is controlled by the controller 32. The carbon dioxide pump 35 is connected to an external carbon dioxide gas source. The carbon dioxide source can be changed to other gas species, such as oxygen.
