Rodent depression model construction device and experiment system

Abstract

The invention relates to a rodent depression model construction device and an experiment system, and relates to the technical field of animal experiment methods and equipment. The rodent depression model construction device comprises a cage frame and a control mechanism, wherein a plurality of cage positions are arranged in the cage frame; a cage body used for containing an experiment animal is fixedly connected in each cage position; a vibration motor is arranged under the cage frame; the top of the vibration motor is connected with the bottom of the cage frame through vibration springs; an electric telescopic rod is also arranged at the upper part of the back surface of the cage frame; the fixed end of the electric telescopic rod is hinged to a wall; the telescopic end of a lead screw ishinged to the back surface of the cage frame; an electric control cabinet is arranged in the control mechanism; and the electric telescopic rod and the vibration motor are electrically connected withthe electric control cabinet. The consistency, the synchronism and the timing performance of experiment operation can be ensured; the operation steps of experimenters can be reduced to the maximum extent; the work efficiency is greatly improved; and the experiment quality is improved, so that the depression molding is efficiently and smoothly completed.

Description

Technical field [0001] The invention relates to the technical field of animal experiment methods and equipment, in particular to a rodent depression model building device and an experiment system. Background technique [0002] The chronic unpredictable stress (CUMS) depression model is an effective animal depression model. The CUMS stress process includes alternating short-term stress and long-term stress. The main stresses include: deprivation of drinking water, deprivation of food, 45° tilt, overnight humid, turn off the lights, strobe light, continuous light, white noise, heat stress in the oven at 42°C, shaking stress, and empty bottle stimulation (empty drinking water) ), peculiar smell stimulation, foreign body stimulation (also tail clipped, swimming in ice water, crowding, etc.), stress stimulation was performed continuously for 35 days. All stresses were randomly given to rats, and all stresses were given the same number of times. Model preparation process In, the rats...

Problems solved by technology

[0003] At present, there is no depression modeling device, and all experimental operations need to be carried out manually. At the same time, it is necessary to purchase a variety of equipment, but it is still impossible to form an experimental system for simultaneous use. There are complex operations, low efficiency, and poor experimental stability. Long, unsatisfactory results, high cost and other defects
