Problems solved by technology

However, there is currently no animal experimental fixator that integrates fixation and pain and temperature stimulation on the market, and some existing fixation devices cannot be used in the experimental environment of functional magnetic resonance imaging due to the limitation of manufacturing materials. Therefore, researchers During the experiment, the operation had to be performed at close range, and the body was vulnerable to the strong magnetic field of the functional magnetic resonance apparatus. At the same time, it was difficult to fix awake animals in the experimental environment of functional magnetic resonance imaging, and there were damage stimuli, which caused the experiment The effect is poor, and the goal is not easy to achieve

Abstract

A fixing apparatus for the remotely controlled pain sense / warmth sense experiment of rat or mouse in functional nuclear magnetic resonance imaging environment is composed of animal fixer, coil fixer, beater for pain sense, and stimulating box for wormth sense.

Description

technical field [0001] The invention relates to a fixing device for animal experiments, in particular to a fixing device for pain and temperature stimulation experiments of conscious large and small experimental mice in the functional nuclear magnetic resonance imaging experiment environment of a medical functional magnetic resonance instrument. Background technique [0002] Animal experiment fixtures are commonly used experimental equipment in the biomedical field. They are used to fix experimental animals for blood collection, drug irrigation, injection, temperature stimulation, pain stimulation and other operations. Chinese patent specification CN2696315Y (announcement on May 4, 2005) discloses a fixture for animals, which is a planar operating platform, or a vertical operating platform formed by combining the operating platform with a support. The platform includes a fixed plate, a chute on it and a fixer on the chute. The chute is a trapezoidal or other shaped raised or...
