Abstract
Description
Technical Field
[0001] This utility model relates to biochemical detection, specifically to a constant temperature device for observing the state of adherent cells under a microscope. Background Technology
[0002] Cell adhesion refers to the process by which adherent cells attach to and spread on a culture surface. The tightness of cell adhesion depends on the characteristics of the cells themselves, the probability of cell-culture surface contact, and the compatibility between the cells and the culture surface.
[0003] In traditional adherent cell culture, once cells reach a suitable degree of confluence, a digestion solution is added to detach them from the culture vessel. The termination of digestion is primarily assessed through manual observation using an inverted microscope. If digestion is incomplete, cells must be transferred to an incubator for further digestion. This process is cumbersome, hinders the accurate determination of digestion time, and easily leads to over-digestion. The success of the adherent cell digestion process directly impacts the viability of the cultured cells.
[0004] In practical use, the main technical problem is that many adherent cells grow in cell culture plates. The adhesion strength of adherent cells is affected by the cell's own characteristics, the probability of cell-culture surface contact, and the compatibility between the cell and the culture surface. The digestion time varies depending on the cell's growth stage. The traditional digestion method involves adding cell digestion solution to the wells, placing them in a constant temperature incubator for a certain time, and then observing them under a microscope. However, the digestion status cannot be observed during the constant temperature digestion period. If digestion is incomplete, the cells must be placed back in the incubator, posing a risk of over-digestion. Temperature has a significant impact on cell growth, and different observation times when adhering cells are removed from the culture environment can lead to inaccurate results. Utility Model Content

A left transparent side panel is provided on the left side of the transparent box and sealed and connected to the constant temperature heaters and the two transparent panels. A transparent sealed flip cover is provided on the right side of the transparent box.

The front of the control panel is equipped with a power switch, warning light, buzzer, control buttons, and digital display screen connected to the control circuit board.

The thermostat includes a transparent box, which contains two transparent plates 6 that are arranged parallel to each other and spaced apart. A temperature sensor is installed between the two transparent plates 6.
[0019] The transparent box is equipped with constant temperature heaters 7 on both the front and rear sides, which are sealed and connected to the two transparent plates 6. On the left side of the transparent box, there is a left transparent side plate that is sealed and connected to the constant temperature heaters 7 and the two transparent plates 6. On the right side of the transparent box, there is a transparent sealing flip cover 8. The upper edge of the transparent sealing flip cover 8 is rotatably connected to the upper transparent plate, and the lower edge of the transparent sealing flip cover 8 is magnetically connected to the lower transparent plate.
[0020] The front of the thermostatic heater 7 is equipped with a control panel, which contains a control circuit board. The temperature sensor and the thermostatic heater 7 are both connected to the control circuit board. The front of the control panel is equipped with a power switch 1, a warning light 2, a buzzer 3, control buttons 4, and a digital display screen 5, all connected to the control circuit board. The control buttons 4 include a timing button and a heating button for adjusting the power of the thermostatic heater 7.
[0021] The time and overall device temperature are set via control button 4, while the digital display screen 5 shows the time and current device temperature in real time. A red warning light 2 and a buzzer 3 alert the operator to stop operation promptly. This device eliminates the need for multiple transfers of cell culture plates between the incubator and microscope, reducing the risk of contamination. The constant-temperature, sealed environment fully utilizes the digestion solution's properties. The alarm system alerts the operator, and continuous microscopic observation allows for convenient control of cell digestion, preventing incomplete or excessive digestion. It can also maintain the culture temperature during microscopic observation of cells.
[0022] In an optional embodiment, the two transparent plates 6 and the transparent sealing flip cover 8 are made of optically high-transmittance glass with a light transmittance greater than 95% to ensure clarity of observation under the microscope. The internal space of the transparent box can be customized according to the size of the microscope stage and the number of cell culture wells to be observed to meet different experimental needs.
[0023] In an optional embodiment, the upper surface of the microscope stage is provided with a positioning groove, the thermostat is placed in the positioning groove, and the bottom of the positioning groove is provided with an anti-slip pad made of rubber to increase the friction between the thermostat and the microscope stage, prevent the thermostat from sliding or shifting during observation, and ensure the accuracy and stability of observation.
[0024] In an optional embodiment, the thermostatic heaters 7 on the front and rear sides are connected in series to ensure that the two thermostatic heaters 7 have the same power, achieve uniform heating, and avoid excessive temperature difference between the front and rear sides of the box.
[0025] In an optional embodiment, the upper edge of the transparent sealing flip cover 8 is rotatably connected to the upper transparent plate via a hinge 9. Felt sealing strips are provided on the contact surfaces of the transparent sealing flip cover 8, the sides of the two transparent plates 6, and the contact surfaces of the constant temperature heater 7 to improve sealing performance. A handle 10 is provided on the right side of the transparent sealing flip cover 8 for easy opening.
[0026] The method of using this utility model is as follows:
[0027] When using this device, first sterilize it and place it on the microscope stage in the cell culture workshop to put the microscope into working condition. Then turn on the power switch 1 and adjust the device temperature and time through the control panel 4. Preheat for more than 15 minutes.
[0028] Then open the sealing flap 8, push the cell culture container into the device, and close the sealing flap 8. The operator can observe the cell status in real time through the transparent plate 6 under a microscope. If the observation is in the digestion stage, the red warning light 2 will flash and the buzzer 3 will sound an alarm after the digestion timer is completed to avoid incomplete or excessive digestion. After digestion is complete, subsequent operations can be performed.
[0029] The entire process is simple and convenient, with digestion under constant temperature conditions, allowing for continuous microscopic observation, reducing the risk of sample contamination and avoiding incomplete or excessive cell digestion. For observation of cells in culture, the temperature can be kept constant during the removal from the culture environment, and the removal time can be standardized to improve the consistency of results.
[0030] In summary, the constant temperature device provided by this invention not only solves the problem of not being able to observe cell state in real time during traditional cell digestion, but also improves the accuracy and efficiency of cell digestion. Through the cooperation of the constant temperature heater and the control circuit board, the temperature inside the device can be precisely controlled, ensuring that cells are digested and observed under optimal temperature conditions. At the same time, the transparent chamber design allows operators to directly observe the cell state under a microscope without removing the cells from the culture environment, thus avoiding the impact of temperature changes on cell growth.
