Experimental device applied to small animal MRI experiment and using method

Abstract

The invention discloses an experimental device applied to a small animal MRI experiment and a using method. The experimental device comprises an animal bed; the animal bed body is divided into an upper bed body and a lower bed body; a tooth rod bracket can be mounted on the lower bed body; the tooth rod bracket is used for connecting the lower bed body with a tooth rod; the tooth rod is used for fixing incisor teeth of a small animal and is provided with a gas anesthesia connecting port; the connecting port can be connected with an external gas anesthesia hose; ear rod brackets can be respectively fixed on two sides of the lower bed body; the ear rod brackets are used for connecting the lower bed body with ear rods; the ear rods are used for fixing the head of the small animal; the upper bed body can slide along the lower bed body so as to change the position relation between the upper bed body and the tooth rod and the ear rods to adapt to small animals with different body sizes; theupper bed body can be connected with an arc-shaped bed cover, wherein the bed cover is used for reducing heat loss of small animals; and a water circulation system is arranged in the upper bed body, wherein warm water can be introduced (flows out) from a water valve at one end of the upper bed body, and the warm water flows through a water bath pipeline to preserve heat of the small animal. The heat preservation requirement on the small animal is met, and anesthetic gas can be introduced.

Description

Technical field [0001] The invention relates to the technical field of detection instruments, in particular to an experimental device applied to small animal MRI experiments and a method of use. Background technique [0002] MRI can not only clearly display the subtle anatomical structure, but also provide rich biochemical information and metabolic information of the tissue, so it is widely used in clinical practice. The application of MRI technology in animal experimental research can not only enable researchers to understand the relevant biological processes and interactions in animals, but also can perform long-term repeated tracking and imaging of the same research individual, which not only ensures the comparability of data, It avoids the influence of individual differences on the experimental results, and does not need to kill the model animals, saving a lot of scientific research funds. With the popularity of the 3T human MRI system, more and more researchers use the 3T M...
