Fixing device for fixing back skin of experimental animal

Abstract

The invention discloses a fixing device for fixing the back skin of an experimental animal, and belongs to the technical field of preventive medicines.The fixing device comprises a base, a fixing net rack is movably arranged on the upper side of the base through a first lead screw adjusting track, a telescopic frame is movably arranged on the upper side of the base through a second lead screw adjusting track, and the telescopic frame is driven by an electric telescopic rod to ascend and descend; clamping rods are installed on the upper sides of the telescopic frames, clamping plates are movably arranged on the sides, close to each other, of the two clamping rods, adjustable limiting rings are alternately arranged at the two ends of the clamping rods, and limiting holding rods are movably arranged on the lower sides of the adjustable limiting rings. By means of the device, efficient and convenient limb limiting and back skin clamping and fixing can be achieved for small animals of different body types, imaging artifacts caused by movement of the small animals are avoided, the imaging quality is improved, and meanwhile damage to limbs and skin caused by excessive clamping of the small animals can be avoided.

Description

technical field [0001] The invention relates to the technical field of preventive medicine, in particular to a fixing device for fixing the back skin of experimental animals. Background technique [0002] In vivo animal imaging technology refers to the application of imaging methods to qualitatively and quantitatively study biological processes at the tissue, cellular and molecular levels in animals in vivo. Animal models are important experimental methods and means in modern preventive medicine research, which help to more conveniently and effectively understand the occurrence and development of human diseases and study prevention and control measures. Advantages, increasing applications in many fields such as medical research and drug development. [0003] The lung is the main organ of the respiratory system. In addition to being in charge of the respiratory function, it also has non-respiratory defense, immune, and endocrine and metabolic functions. In order to study lu...

AI Technical Summary

Problems solved by technology

[0005] The fixation device in the prior art has the following disadvantages when used: when the fixation device fixes the back skin of the experimental animal, the animal is likely to cause limb movement due to fright after it is clamped. However, the animal needs to keep as still as possible during the scanning period. Therefore, the fixing device is not conducive to the actual scanning operation, so the present invention proposes a fixing device for fixing the back skin of experimental animals
