Description

Technical Field

[0001] This utility model relates to the field of medical experimental equipment technology, and in particular to an integrated device for mouse fixation, photography and weighing. Background Technology

[0002] Mice are commonly used laboratory animals in medical research, and are also frequently used in experiments in medical physiology, pharmacology, pathology, and pathophysiology. In the fields of biomedical and pharmaceutical research, laboratory animal models, especially mouse models, are widely used in disease mechanism research, drug screening, and efficacy evaluation. Due to their high similarity to humans in the genome, short reproductive cycle, and low experimental cost, mice have become the preferred choice for constructing many disease models. Especially in areas such as metabolic diseases, cardiovascular diseases, neurodegenerative diseases, tumors, and immune system diseases, mouse modeling technology has become an indispensable part of basic research.

[0003] Tail vein injection in mice is a commonly used injection method in pharmacology, toxicology, genetics, oncology, immunology, and other experimental fields. However, despite its widespread use, tail vein injection still faces a series of technical challenges in practice. Especially during the establishment of mouse models, live mice often exhibit a degree of activity, which can lead to operational difficulties. For example, the mouse's tail may be difficult to stabilize during drug administration, affecting injection accuracy. Furthermore, it is usually necessary to photograph the modeling site during experiments for subsequent data analysis. However, live mice often exhibit vigorous movement during modeling, making it difficult to stabilize the photographic equipment, thus affecting the photographic quality and the accuracy of the data.
