Description

A self-cleaning environment-friendly multifunctional laboratory mouse breeding cage system

technical field

The invention relates to the field of animal experiment equipment, in particular to an automatic-cleaning and environment-friendly multifunctional laboratory mouse breeding cage system.

Background technique

In modern medical experiments, animal experiments are indispensable experiments, and experimental animal feeding is an important basis for carrying out animal experimental research. Among them, the largest scale is the breeding of rats. Traditional rat breeding is generally breeding cages, which are composed of breeding cages, cage racks, water bottles, bedding, etc. During feeding, water, feed, and bedding need to be regularly supplied every day. And so on, it is necessary to turn on and off the lights at regular intervals every day. Some experiments also require noise stimulation, light stimulation, diet control, drinking water, cage tilting, rotation, and other stimuli.

The traditional breeding cage is an open plastic box enough to accommodate a rat. The top of the plastic box is provided with a buckled wire mesh cover, and a drinking bottle with a suction nozzle is placed on the wire mesh cover, and the suction nozzle is inserted into the plastic box through the wire mesh cover. In the box, to facilitate the rats to drink water. The food is then directly dropped into the box body for the mice to eat. It is usually necessary to place litter in a plastic box to facilitate the cleaning of the cage. Due to the limited space in the laboratory, the rearing cages are generally placed on rearing racks with wheels at the bottom.

This feeding device has the following disadvantages:

1. When it is necessary to regularly stimulate the squirrel cage rotation, the experiment is usually carried out by manually dragging the feeding shelf to rotate, which is time-consuming and laborious. And need larger space, has limited the feeding quantity of experimental mouse.

2. Because rats excrete feces, the litter in the cage needs to be replaced manually every 3 days, and the working conditions are harsh.

3. When it is necessary to regularly stimulate the squirrel cage, the experiment is usually carried out by manually placing a backing plate on one side of the bottom of the squirrel cage. When the test is completed, the backing plate is removed, which consumes manpower.

For the above-mentioned traditional breeding device, 5-6 people are needed to complete the experiment, which greatly reduces the scientific research time of the scientific research personnel and increases the cost of the experiment.

According to the setting, the flushing controller realizes that the bottom cleaning nozzle regularly sprays water to clean the bottom slope of the breeding cage, the waste water enters the waste water pipe, and enters the sewer after converging at the bottom, so as to ensure timely cleaning of feces and urine without manual cleaning, avoiding untimely cleaning, and cages If there are problems such as internal organs and odors, ensure that the breeding cages are clean and hygienic without odors.

The lamp can be turned on and off at a fixed time, and can also be changed to other colors according to needs, and the intensity of the light can be adjusted to realize light stimulation without manual operation, and forgetting to switch the light, switching the light on time, inaccurate stimulation time, and lamp stimulation Inconsistencies in intensity etc.

The central axis rotation system is responsible for the rotation, the bottom chassis is larger and heavier, and there is a gap at the bottom, which can be connected to the ground through expansion screws to ensure the stability during rotation. There are struts on the central axis and individual cages to ensure tight connection.

The purpose of the present invention is to provide the technical problem to be solved by the present invention is: provide a kind of feeding system used for experimental mice, this feeding system is easy to use, saves a lot of time, manpower and funds, fully realizes automation, and is easy to be widely used.
