Description

Technical Field

[0001] The utility model relates to the technical field of bioengineering accessories, in particular to an auxiliary observation device for a microscope, which is mainly used for observing cell states and confluence rates in laboratories. Background Art

[0002] During the production of the stock solution of freeze-dried human rabies vaccine (human diploid cells), observation of cell status and confluence is crucial. This not only affects cell growth and proliferation, but also has a direct impact on cell culture quality control and subsequent cell passaging. It is also a key factor affecting the antigenicity of intermediate products. Therefore, ensuring good observation of cell status is a key step in the production process.

[0003] In the daily process of observing cells using an inverted microscope, in order to fully observe the growth status of adherent cells, it is necessary to observe various positions of the cell factory and take photos of representative points for preservation. However, existing microscope storage platforms are usually small in size and cannot accommodate larger cell factories. Especially when observing the edges of cell factories, due to the large volume of the cell factory, the size limitation of the microscope storage platform makes it impossible to place most of the volume of the cell factory on the platform. In addition, the cell factory contains liquid, and the center of gravity is easily shifted, resulting in the risk of the cell factory falling, thereby affecting the accuracy and safety of observation.

[0004] Currently, the main method to solve this problem in production is for the operator to hold the cell factory steady by hand and then observe. This method has the following disadvantages:

[0005] Operators need to maintain a stable hand-held position, which limits their ability to move freely and operate other equipment; holding the cell factory for a long time can easily cause fatigue, increasing the possibility of operational errors; even a slight shake of the hand may cause the cell factory to tilt or fall; in the handheld state, the liquid level in the cell factory is prone to fluctuations, affecting observation and photography quality; manual operation increases the risk of contamination and poses a potential threat to the operator's personal safety. Utility Model Content

[0006] In order to make up for the above-mentioned shortcomings, the utility model provides an auxiliary observation device for a microscope. By increasing the placement area of ​​the microscope storage platform and providing a stable fixed structure, the stability of the cell factory during the observation process is ensured, the operational error rate is reduced, the contamination risk is reduced, and the observation quality and operational safety are improved.

[0007] The utility model is realized through the following technical scheme: an auxiliary observation device for a microscope, the technical key points of which are: it includes a factory placement platform that is fitted with the left side of the microscope placement platform, and a limiting groove is provided on the upper part of the factory placement platform; a square through hole is also provided on the factory placement platform; sliding supports that slide inside the square through hole are symmetrically provided on the front and rear sides of the factory placement platform; a transverse limiting support rod that slides with the telescopic sliding support is provided on the outer side of the telescopic sliding support, and the right end of the limiting support rod is provided with a limiting baffle that is fitted with the right side of the microscope placement platform; a telescopic frame for supporting the factory placement platform is fixedly provided at the bottom of the factory placement platform, and a base is fixedly provided at the bottom of the telescopic frame; bolt holes are also provided at the bottom of the limiting support rod and the factory placement platform, and a limiting bolt that is threadedly fitted therein is provided in the bolt hole.

[0008] Furthermore, the bottom of the limiting groove is on the same horizontal plane as the upper surface of the microscope placement platform.

[0009] Furthermore, a drawer guide rail for sliding fit is provided between the sliding support and the limiting support rod.

[0010] Beneficial effects and features of the utility model:

[0011] Increased storage area: By adding a factory placement platform, the effective storage area of ​​the microscope platform is significantly increased. This allows larger cell factories to be completely placed on the platform, avoiding the inconvenience of observation caused by platform size limitations.

[0012] Stable fixed structure reduces contamination risk: A retaining groove is located on the top of the cell factory placement platform. The groove's dimensions match the cell factory's, firmly securing it and preventing it from moving or falling during observation. The bottom of the retaining groove is aligned with the top surface of the microscope platform, ensuring stable placement of the cell factory and a stable liquid level. This improves observation accuracy, significantly reduces the risk of contamination from falling, and protects the operator's personal safety.

[0013] Flexible Adjustment: The design of the sliding support and transverse limit rod allows the device to adapt to microscope platforms of varying sizes. A drawer guide is provided between the sliding support and the limit rod, allowing the transverse limit rod to slide freely within the square hole, allowing for easy adjustment to the desired fixed position. The limit baffle ensures a tight fit between the transverse limit rod and the microscope platform. The limit bolt design ensures that the sliding support and transverse limit rod are firmly fixed after adjustment, preventing the risk of loosening or falling off during observation and enhancing the fixing effect.

[0014] Easy and safe operation: Operators no longer need to manually hold the cell factory steady, reducing operational errors and fault tolerance, thereby improving operational safety. Improved observation quality and efficiency: The cell factory can be manually moved left and right within the positioning groove, facilitating observation and photographing at different locations. The stable fixed structure ensures the stability of the cell factory and a steady liquid level during observation, improving observation quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A square through hole 102 is also provided on the factory placement platform; sliding supports 2 that slide inside the square through hole are symmetrically provided on the front and rear sides of the factory placement platform, and the front and rear sliding adjustment sliding supports are used to match microscope storage platforms of different sizes; a transverse limit support rod 4 is provided on the outside of the telescopic sliding support, which slides with it left and right, and the right end of the limit support rod is provided with a limit baffle 401 that fits with the right side of the microscope storage platform. The transverse limit support rod is adjusted left and right to match microscope storage platforms of different sizes; a telescopic frame 5 for supporting the factory placement platform is fixedly provided at the bottom of the factory placement platform, and a base 6 is fixedly provided at the bottom of the telescopic frame. The telescopic frame is used to adjust the height of the factory placement platform, and the base is used to ensure the stability of the entire device; bolt holes are also provided at the bottom of the limit support rod and the factory placement platform, and a limit bolt 7 that cooperates with its thread is provided in the bolt hole; by tightening the limit bolt, the adjusted sliding support and the transverse limit support rod can be fixed to avoid loosening or falling off during observation.
