AI Technical Summary
Technical Problem
Mice cannot be fixed during tail vein blood glucose testing, making blood collection difficult and increasing the risk of biting the operator.
Method used
A fixation device including a tail limiting device, a head limiting component, a cylinder and a blood collection plate was designed. The device uses a push rod motor and an infrared ranging sensor to achieve automated fixation and anesthesia of mice, and combines an anesthetic gas system for fixation and blood collection.
Benefits of technology
This method effectively immobilizes mice, reduces the psychological barriers for operators and the impact of mouse hyperactivity on experimental results, and improves detection efficiency and blood collection accuracy.

Abstract
The application relates to the field of medical experiment technology and provides a mouse fixing device for measuring blood sugar of the tail vein of an experimental mouse. The device comprises a cylinder vertically arranged on a bottom plate and used for accommodating the body of the experimental mouse, the two ends of the cylinder are open, a slot extending from the first end face of the cylinder to the second end face of the cylinder is arranged above the cylinder and used for accommodating the tail of the experimental mouse which is dragged, the first end face of the cylinder is provided with a guide slot used for providing a guiding action of drawing into the cylinder for a head limiting component, a blood sampling groove is arranged on the bottom plate at a position corresponding to a tail limiting fixing device, and a blood sampling plate is used for being inserted into a slot between the tail limiting devices or a gap between the tail limiting devices and the second end face of the cylinder. The mouse fixing device for measuring blood sugar of the tail vein of the experimental mouse can conveniently accommodate the mouse into the fixing device and easily perform blood sampling on the tail of the mouse, so that the requirement of laboratories on blood sampling of the tail vein of the mouse can be met.
