Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of mouse feces classification and collection, and particularly relates to an aseptic and sterilizable mouse feces classification and collection device. Background Art
[0002] In recent years, the study of intestinal flora has gradually become a hot topic in the medical field. The intestinal flora refers to the microbial community in the human intestine, including bacteria, fungi, viruses and other microorganisms. These microorganisms co-evolve with the host, are closely related to human health, and affect many aspects of physiological and pathological processes.
[0003] By using advanced sequencing technology and bioinformatics analysis methods, researchers have conducted in-depth studies on the role of intestinal flora in human health and disease. Many studies have found that intestinal flora is closely related to the human immune system, metabolism, nutrient absorption, etc., and even affects mental health and nervous system function. In addition, intestinal flora also plays an important role in the occurrence and development of many diseases. For example, intestinal flora imbalance may lead to the occurrence of intestinal inflammatory diseases, obesity, diabetes and other diseases. Therefore, studying the composition and function of intestinal flora is of great significance for the prevention and treatment of these diseases.
[0004] In the study of intestinal flora, mouse feces is an important source of samples. The method of collecting feces and the quality of the feces obtained play a decisive role in the accuracy and stability of the study. A good feces collection method is the guarantee of accurate experimental results. There are several common methods for collecting mouse feces, including stress defecation (tail-lifting method), natural defecation collection and metabolic cage collection. Among them, stress defecation collection is currently used more in experiments. Wear disposable gloves during the operation, first lift the mouse tail with your right hand, place it on a mouse cage or a rough surface, fix the mouse, and then gently press the lower abdomen of the mouse to stimulate its defecation, and then collect the feces for the next step of processing. The main advantage of this method is that it is simple to operate, but the disadvantages are also very obvious: first, the sterility of the environment cannot be guaranteed during the operation, and the fecal samples are easily contaminated during the collection process, thereby affecting the experimental results; second, frequent stress defecation may bring a certain degree of physical and mental stress to mice, affecting their physiological state and behavioral performance, and causing discomfort; third, the samples collected by the stress defecation method may be affected by stress factors, resulting in temporary changes in the flora structure, which is not representative. The biggest problem with this method in our experiment is that if researchers have to collect mouse feces multiple times, as the mice adapt to stress, it becomes increasingly difficult to collect feces in the later stages, and often it is impossible to collect enough feces even after a long period of stimulation. This leads to a decrease in the comfort of the experimental animals and has a significant impact on the experimental process and results. Therefore, the defects of this method are very obvious, but because it is simple and easy to use, many people still use it in actual experiments.
[0005] The natural defecation collection method is also a commonly used feces collection method in the experiment. This method allows mice to defecate in a natural environment, and then collects feces samples in time for analysis. The specific operation method is to put the mice to be sampled into a clean cage covered with sterilized filter paper; let the mice defecate naturally, and collect feces samples immediately after the mice defecate for the next step of processing. The advantage of this method is that it can better reflect the true physiological state of the mice, the collected feces samples are more representative, and the operation is relatively simple and convenient. However, the disadvantages of this feces collection method are also obvious: First, the collection time is uncertain: because the defecation time of the mice cannot be controlled, the time point for scientific researchers to collect samples is uncertain, which is not conducive to the time management of the experiment. If the feces are not collected and processed immediately after defecation, it is likely to cause the feces sample to be contaminated, affecting the accuracy of the experiment. Second, the number of feces samples collected is unstable. In the process of feces collection, sometimes there is a situation where the number of samples is still insufficient after waiting for a long time, especially in experiments that require a large amount of sample data. Third, it is easily affected by environmental factors. Mice may have defecation preferences under different environmental conditions, affecting the consistency and comparability of samples. This method is time-consuming and laborious when we discover key problems in actual operations, and the collected fecal specimens are easily contaminated by the environment, resulting in a decrease in the efficiency and quality of sample collection, which greatly affects the subsequent experimental rhythm and efficiency.
[0006] The metabolic cage feces collection method is also a mouse feces collection method currently used in laboratories. This method places mice alone in metabolic cages to collect feces samples from mice for analysis. The metabolic cage is a feces and urine separation device, which is mainly used to collect feces and urine naturally discharged by experimental animals. The special result is that the feces and urine of experimental animals can be collected separately for research at the same time. Its advantage is that metabolic cage feces collection can sample each mouse individually to ensure the individualization and purity of the sample. At the same time, it is easy to operate and has less external interference, which is conducive to the accuracy of the data. However, its defects are also obvious: First, the space and equipment requirements are large. Metabolic cage feces collection requires more metabolic cages and space, which will greatly increase the cost of the experiment. If a limited number of metabolic cages are used to sample experimental mice in batches, the fecal samples may be affected by the time difference, thereby affecting the accuracy of the experiment. Second, the metabolic cage is different from the daily mouse breeding cage. Being confined in the metabolic cage for a long time may have a certain impact on the physiological state of the mouse and affect the reliability of the experimental results. Third, the metabolic cage is not easy to clean. Due to its large size and complex structure, it is very difficult to fully clean, disinfect and sterilize the metabolic cage. An unclean environment is likely to affect the quality of the fecal sample, which will affect the accuracy of the experimental results. In actual experiments, we found that the biggest flaw of this method is that the metabolic cage is difficult to clean thoroughly during use. The large size and complex structure make it difficult to fully disinfect and sterilize it, which brings great instability to the sterile collection of feces, which will affect the accuracy of subsequent experiments.
[0007] In summary, the ideal conditions for collecting mouse feces are sterility, high efficiency, and controllable conditions. The experimental animals should be kept in the same state as much as possible during collection, and the comfort of the experimental animals should be ensured. However, all current mouse feces collection methods cannot meet the above requirements at the same time, which is an urgent problem for researchers in the field of intestinal flora.

[0042] Working principle: Example 1: Figure 1 , 2 , 3, 4 and Figure 5As shown, by placing mice into multiple compartments separated by multiple partitions 8, and then closing the transparent door panel 17, the motor 10 can be started at a fixed time to drive the synchronous belt 11 and multiple turntables 7 to rotate, thereby driving the second transmission belt 906 and the first conveying device 901 to continuously change the inclined state and the horizontal state. When the second transmission belt 906 is in a horizontal position and the first conveying device 901 is inclined, the mice will be prompted to run onto the second transmission belt 906, and the second transmission belt 906 is used for the mice to rest and defecate.

The whole process realizes a sterile mouse living experimental cage, realizes the regular work and rest of the mice, and is convenient for understanding and collecting the mouse feces at regular times for collection experiments;
[0043] Embodiment 2: Figure 1 , 2 , 5, 6 and Figure 8 As shown, the turntable 7 is used to drive the second transmission belt 906 and the first conveying device 901 to rotate periodically, and alternately become a horizontal plane. During this period, when the second transmission belt 906 is in the horizontal plane, the mouse is in a free state on the second transmission belt 906, and the mouse in the relaxed state is more likely to defecate. When the first conveying device 901 is in the horizontal plane, the mouse moves on the first conveying device 901, and at the same time, the rotation of the first conveying device 901 causes the rubber ring 1 902 to be squeezed onto the rubber ring 2 903;
[0044] At this time, when the first conveying device 901 is in a horizontal state, the second motor 908 is started to drive the second transmission belt 906 to move. The moving second transmission belt 906 scrapes the feces on the surface through the design of the scraping blade 909 and drops it into the collection tank 202. At the same time, the rubber extrusion friction is used to drive the rubber ring 903 to rotate. During this period, the fixed frame 904 is a two-stage design. One end of the rubber ring 903 and the synchronous belt 905 is sleeved and connected to the end fixed on the partition 8 through a bearing. The rubber ring 902 is used to drive the rubber ring 903 and the synchronous belt 905 to rotate.
