Description

Technical Field

[0001] This invention relates to the field of tumor research technology, specifically to an experimental device for inhibiting tumor cell growth. Background Technology

[0002] In the field of tumor research, it is crucial to explore the mechanisms that inhibit tumor cell growth, screen effective anti-tumor drugs, and evaluate the effects of various treatment strategies. However, existing tumor cell experimental devices have many limitations, which seriously restrict the efficient conduct of related research.

[0003] Traditional cell culture containers, such as ordinary culture flasks and culture dishes, cannot accurately simulate the complex microenvironment of tumor cells in vivo when culturing tumor cells. Tumor cells exist in a dynamic environment with multiple interacting factors in vivo, including cell-to-cell communication, cell-extracellular matrix interactions, and specific physicochemical gradients. These key factors cannot be effectively reproduced in conventional culture containers, resulting in significant deviations between in vitro experimental results and actual in vivo conditions. This affects the accurate assessment of tumor cell growth characteristics and drug efficacy.

[0004] In the drug processing stage, there is a lack of optimized designs specifically for drug sensitivity testing of tumor cells. Existing drug addition methods are often not precise or flexible enough, making it difficult to achieve efficient screening of multiple drugs, different concentrations, and complex drug combinations. This not only prolongs the experimental cycle and increases experimental costs, but may also lead to inaccurate and unreliable experimental results due to errors in the drug addition process.

[0005] Among the existing experimental instruments, there is no dedicated device for the overall experiment of inhibiting tumor cell growth. During the experiment, it is impossible to effectively control the concentration of carbon dioxide and temperature, which prevents the tumor cells from achieving the expected effect during drug culture, thus affecting the evaluation of the entire experimental results and resulting in low experimental accuracy.
