Description

Modularization animal transfer device suitable for under nuclear magnetic resonance environment

Technical Field

The invention belongs to the technical field of animal transfer devices, and particularly relates to a modular animal transfer device suitable for a nuclear magnetic resonance environment.

Background

Magnetic Resonance Imaging (MRI) is an instrument that uses changes in a magnetic field to perform imaging. It has been widely used in various fields of biological research and has the characteristics of multi-angle imaging, high-resolution imaging, rich image information and the like. However, in the process of using animals for MRI detection, the preservation and transportation of animals has been a difficult problem for researchers, and is specifically shown in the following aspects:

1. the transfer work of the small animals needs to be independently solved by scientific research personnel, sometimes the scientific research personnel have to place the animals in an MRI operating room and operate in the environment where people and livestock coexist, so that the relatively clean environment of the operating room is polluted, the risk of infecting the diseases of people and livestock is increased, and great threat is brought to the health of the scientific research personnel;

2. at present, metal structures exist in most small animal transfer devices, the metal structures are dangerous to use in an MRI machine room, and the metal structures can be sucked into a magnetic field center by the MRI machine in the MRI machine room to cause damage to the MRI machine, so that most of the existing animal transfer devices are not suitable for being used in the MRI machine room;

3. at present, most of known animal transfer devices are too narrow in application range, mainly have a closed structure and a single size, and can only be used for animals of the same strain, so that the use efficiency of the transfer device is greatly reduced, and meanwhile, when a large number of animals are transferred, more manpower and material resources are required to be invested, and the difficulty in transportation is increased;

4. some animal transfer devices for mass transport are known to be in many places with unreasonable structures, for example, a large number of animals are placed in the same space, which not only can cause disease transmission among different animals, but also is not beneficial to the identification and the taking of the animals; the air generated by air exchange by using the single pore channel is not smooth in circulation, so that the growth of microorganisms and the generation of stink can be caused, and carbon dioxide can be gathered to influence the living state of animals;

therefore, a modular animal transfer device suitable for the nuclear magnetic resonance environment is provided.
