Description
Technical Field
The invention relates to the technical field of biomedicine, in particular to a mouse raising cage capable of monitoring environmental indexes of living big and small mice.
Background
In the biomedical field, experimental animals have irreplaceable roles as fundamental tools for biological and medical research. Therefore, the quality of the experimental animals is also more and more paid attention to scientific researchers, and the quality of the experimental animals is closely related to the living environment of the experimental animals. The rats and mice are the most commonly used experimental animals, and have the habit of day and night movements, fear of convulsion, biting, stronger disease resistance, extremely sensitivity to changes of environmental indexes such as illumination, ammonia, temperature, humidity and the like, and once the indexes exceed a safe range, the discomfort and the disease initiation of the rats and the mice are easy to cause, so that the accuracy of experimental results is reduced.
First, rats and mice are very sensitive to light, and studies have reported that lactating mice are prone to neurological disorders under relatively intense light, and that eating mice may occur. The illumination time also has negative effects on learning and memory capacity, neuroendocrine, estrus cycle disorder and the like of rats and mice. The influence of illumination on experimental animals is more and more emphasized, and under the condition that closed type feeding has become mainstream, artificial illumination gradually replaces natural illumination, but the control of illumination time, illumination intensity, illumination wavelength and illumination uniformity in the current scheme is unsatisfactory.
Secondly, the study found that ammonia concentration in the feeding environment had a large effect on rats and mice. Ammonia gas is used as an important environmental index and is closely related to the quality control of experimental animals. The higher the ammonia concentration, the greater the influence on animal health, and the high ammonia concentration can attack animal welfare on one hand, and on the other hand, ammonia can cause the damage of respiratory tract mucous membrane, thereby leading to the occurrence of respiratory system diseases.
In addition, the temperature of the raising environment is one of determining factors for the heat balance and regulation of experimental animals, the temperature directly influences the comfort level of the experimental animals, the temperature can influence the concentration of ammonia in the environment, and the solubility of the ammonia is lower along with the rise of the temperature, so that the concentration of the ammonia in a squirrel cage is higher. In addition, too high and too low a temperature can affect the animal's heat balance and regulation, causing discomfort to the animal. Excessive rapid or excessive changes can cause adverse reactions in behaviors and physiology, and cause damage to rat and mouse organisms. When the temperature is too high, the appetite of the animals is vigorous, the food intake is increased, and when the temperature is too low, the appetite of the animals is reduced, the food intake is reduced, and the physiological function is changed, so that the growth of the animals is influenced.
Humidity is also an important environmental index, the change of the humidity inevitably affects the heat production and the heat dissipation of animals, if the humidity is too high, the evaporation of animal organisms is inhibited, metabolic disturbance is easily caused, the resistance of the animal organisms is reduced, and the incidence rate is increased; too low a humidity may cause agitation, neurological disorder, respiratory disease, and ring tail disease in animals, and the female mice may reject lactation and feed.
It can be seen that rats and mice are highly sensitive to the above indicators, and if the control is not good, the experimental results obtained will be affected finally, resulting in serious waste of resources.
Rat and mouse rearing cages are used as daily tools for rearing management, and the rats are directly contacted with the rearing cages every day, so that the environmental indexes directly affect the rats or the mice in the cages. Therefore, along with the increasing requirements of the biomedical field on the fine breeding of experimental animals, the environmental indexes of the cage where the rats or the mice are located should be directly and strictly detected, so that the harmful environmental factors in the breeding process are timely eliminated, and the credibility and the repeatability of experimental results are improved.
However, the existing rat or mouse rearing cage needs to judge the environmental quality either by subjective judgment of a breeder or can only detect certain functions or indexes, and the environmental indexes are rarely considered at the same time, especially under the condition that the requirement on experimental animal management is higher and higher, the influence of the environmental factors of the experimental animal on the experimental animal and the interference of the experimental result are difficult to remove by considering the single indexes. Therefore, in order to maintain the consistency of the factors except the intervention conditions of the rats and the mice in the experimental group, it is necessary to invent a novel rat rearing cage so as to realize the detection of the environmental index and further reduce the influence of the environmental factors on the experimental rats or mice.

the temperature and humidity monitoring assembly comprises a capacitive humidity sensor, and the capacitive humidity sensor is electrically connected with an external computer controller through an analog signal digital signal converter; the capacitive humidity sensor is embedded at the bottom of the inner layer of the cage body, padding is laid at the bottom of the inner layer, and the capacitive humidity sensor is embedded at the bottom layer of the padding; the pad humidity can be directly monitored, damage of animals to the capacitive humidity sensor is prevented, and the capacitive humidity sensor is protected;
the rat rearing cage adopts black organic plastic, eliminates the interference of light rays outside the cage on animals in the cage, and realizes absolute control of illumination of big and small rats in the cage; the LED lamp panel arranged in the cage cover is adopted, the convex lens is utilized to convert light into parallel light, the uniformity of the light in the cage is increased, and the PC light diffusion plate is additionally arranged below the convex lens, so that the eyes of the mice are prevented from being directly exposed to LED lamp light to cause damage; the quantity of the turned-on LED lamps is controlled by a computer, so that the bright-dark gradual change effect of natural light is simulated, and the sudden appearance or disappearance of the light is prevented from causing mental stimulation to the mice;
the raising cage is provided with an inner layer and an outer layer, on one hand, a plurality of gaps for communicating gas in the cage with the inner layer and the outer layer are arranged at the upper parts of the front and rear cage walls on the left and right sides of the inner layer, so that the temperature and the ammonia concentration of the gas in the cage are consistent with those of the gas in the gaps; on the other hand, the design of the inner layer and the outer layer is beneficial to the arrangement of the sensor, and the temperature sensor and the ammonia sensor are arranged in the gaps between the inner layer and the outer layer, so that the detection of corresponding indexes is realized, and the damage of rats or mice to the sensor is avoided; the humidity sensor is used for detecting the humidity of padding, and the independent padding humidity sensor is inlaid at the bottom of the inner layer of the rearing cage, so that the detection of the padding humidity is facilitated, and the damage of animals to the sensor can be prevented while the detection of indexes is facilitated.
