The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A specific structure of an animal excrement collecting apparatus according to an embodiment of the present invention will be described with reference to fig. 1 to 3.

As shown in fig. 1, the animal waste collecting device according to the embodiment of the present invention includes a cage 1, a collecting assembly 2, a collecting cage 3 and a temperature control member 4, wherein the lower end of the cage 1 is open, and the cage 1 is configured to accommodate an experimental animal. The collecting assembly 2 is located the below of the cage body 1, the collecting assembly 2 comprises a housing 21, a net body 22 and a filtering piece 23, the two ends of the housing 21 are opened and arranged, the upper end of the housing 21 is arranged corresponding to the lower end of the cage body 1, the net body 22 is arranged inside the housing 21, the upper end face of the net body 22 is configured to support the experimental animal, the filtering piece 23 is clamped between the peripheral face of the net body 22 and the housing 21, the filtering piece 23 is configured to absorb the urine of the experimental animal, the collecting cage 3 is provided with a collecting hole 31 correspondingly arranged at the lower end of the housing 21, the temperature control piece 4 is arranged on the collecting cage 3, and the temperature control piece 4 is configured to control the temperature of the collecting cage.

It will be appreciated that at the start of the experiment, the laboratory animal is placed in the cage 1 and stands on the upper end face of the net body 22, and that during the experiment, faeces discharged from the laboratory animal may pass through the net body 22 and through the collecting opening 31 into the collecting cage 3. Because the temperature control part 4 is arranged on the collecting cage 3, the temperature of the collecting cage 3 can be controlled by the temperature control part 4, the collecting cage 3 is always at a relatively low temperature by adjusting the working state of the temperature control part 4, the animal excrement collected in the collecting cage 3 is ensured to be at a lower temperature, and therefore, the extraction of DNA and RNA from the animal excrement by experimenters is facilitated. In addition, because the filter element 23 for absorbing animal urine is arranged between the shell 21 and the net body 22 of the collecting assembly 2, the urine and the excrement are separated, and the urine is prevented from entering the collecting cage 3.

According to the animal excrement collecting device provided by the embodiment of the invention, the collecting assembly 2 comprises the filter element 23 capable of absorbing animal urine, so that the urine and excrement of an animal can be well separated, and only excrement of an experimental animal enters the collecting cage 3. In addition, because the temperature control part 4 for adjusting the temperature of the collecting cage 3 is arranged on the collecting cage 3, the temperature control part 4 can control the temperature of the collecting cage 3 at a lower temperature, and the animal excrement collected in the collecting cage 3 is ensured to be at a lower temperature, thereby being convenient for experimenters to extract DNA and RNA from the animal excrement.

In alternative embodiments, the temperature-control member 4 can be an ice bag or a dry ice bag, which both ensures that the collecting cage 3 is at a lower temperature and reduces the cost of the temperature-control member 4. Of course, in other embodiments of the present invention, the temperature control member 4 may be a refrigeration semiconductor, and the collection cage 3 can be at a relatively precise and stable temperature by using the refrigeration semiconductor as the temperature control member 4, so as to be more beneficial for the experimenter to extract DNA and RNA. In order to further guarantee that the collecting cage 3 is in a constant temperature state, the temperature control part 4 can further comprise a temperature detection part attached to the collecting cage 3, the temperature detection part is electrically connected with a refrigeration semiconductor, and the refrigeration semiconductor can adjust the working state of the refrigeration semiconductor according to the detection result of the temperature detection part.

In some optional embodiments, the side surface of the collecting cage 3 attached to the temperature control member 4 is made of a heat transfer material, and the other side surface of the collecting cage 3 is made of a heat insulation material, so that the temperature control member 4 can be ensured to better cool the collecting cage 3, and the influence of the ambient temperature on the collecting cage 3 is reduced.

In some alternative embodiments, the filter 23 is a sterile RNA Free filter paper, thereby preventing the filter paper from contaminating the feces after the feces contact the filter paper, and further affecting the normal experimental results. Of course, in other embodiments of the present invention, the filter element 23 may also be other filter structures capable of absorbing liquid, and is not limited to the filter paper of this embodiment.

in some embodiments, as shown in fig. 2, the housing 21 comprises a tapered section 211 and a flat section 212, the tapered section 211 is connected to the cage 1 at an upper end thereof, the tapered section 211 has a cross-sectional area that gradually decreases in a downward direction, the flat section 212 is connected below the tapered section 211, and at least a portion of the flat section 212 is inserted into the collecting hole 31. It can be understood that, although the filter paper is disposed between the casing 21 and the net body 22, and the two ends of the casing 21 are opened, urine of the experimental animal in the cage 1 may directly pass through the casing 21 and drop into the collecting cage 3 when urinating, thereby being not beneficial to collecting feces by the experimenter. In the embodiment, since the housing 21 includes the tapered section 211, the cross-sectional area of the tapered section 211 is gradually reduced in the downward direction, so that the probability that the urine of the experimental animal in the cage body 1 may directly drop to the collecting cage 3 through the housing 21 when urinating is reduced, and the function of separating the urine and the feces of the animal feces collecting device is better realized. Furthermore, the housing 21 comprises a straight section 212 inserted into the collection opening 31, so that it is avoided that the faeces of the laboratory animal escape from the connection gap between the housing 21 and the collection cage 3 and contaminate the laboratory. It should be added that, in the embodiment of the present invention, the tapered section 211 may be a conical shape or a square tapered shape, and the straight section 212 may be a round pipe or a square pipe, which may be selected according to experimental needs, and specific shapes of the tapered section 211 and the straight section 212 are not limited herein.

In some specific embodiments, as shown in fig. 2, the net body 22 comprises a disk-shaped net 221 and a conical net 222, the disk-shaped net 221 is arranged corresponding to the lower end of the cage body 1, the conical net 222 is connected below the disk-shaped net 221, the conical net 222 is matched with the conical section 211 in shape, and the filter element 23 is clamped between the conical net 222 and the conical section 211. It can be understood that, in the experimental process, the experimental animal is placed on the disc-shaped net 221, on one hand, the disc-shaped net 221 can play a role of supporting the experimental animal, so as to ensure that the experimental animal can be stably positioned in the cage body 1, on the other hand, the disc-shaped net 221 can ensure that the excrement discharged by the experimental animal can pass through the net body 22 and fall into the collecting cage 3, and the phenomenon that the excrement is stuck on the disc-shaped net 221 is avoided. In addition, the shape of the conical net 222 is matched with that of the conical section 211, so that the phenomenon that excrement is clamped between the conical net 222 and the conical section 211 due to the fact that the distance between the conical net 222 and the conical section 211 is different is avoided.

Optionally, the disk-shaped net 221 is provided with a latch (not shown) configured to be snapped onto the cage body 1. Thereby, the stability of the disk net 221 is ensured, thereby ensuring the stability of the experimental animal.

Optionally, the disk-shaped mesh 221 is a strip mesh and the conical mesh 222 is a cross mesh. Of course, in other embodiments of the present invention, the specific types of the disk-shaped net 221 and the conical-shaped net 222 may be selected according to actual needs, and are not limited to the strip-shaped net and the cross net of the present embodiment.

Optionally, the end face of the disk-shaped mesh 221 is not higher than the upper end face of the conical section 211. Thus, the phenomenon that the feces discharged from the experimental animal standing on the disk-shaped net 221 leaks from the gap between the end surface of the disk-shaped net 221 and the upper end surface of the tapered section 211 can be avoided to some extent.

In some alternative embodiments, the housing 21 is a plastic member and the mesh body 22 is a metal member.

in some alternative embodiments, the tapered section 211 is formed as a cone, and the ratio of the minimum diameter to the maximum diameter of the tapered section 211 is between 1/10 and 1/7. It will be appreciated that the small difference between the maximum diameter and the minimum diameter of the conical section 211 increases the probability of urine from the laboratory animal dripping directly through the housing 21 into the collecting cage 3, and that a large difference between the maximum diameter and the minimum diameter of the conical section 211 results in a large size of the collecting assembly 2 as a whole, thus resulting in wasted space. In this embodiment, the ratio of the minimum diameter to the maximum diameter of the conical section 211 is controlled between 1/10 and 1/7, which both reduces the chance of urine from the test animal dripping directly through the housing 21 into the collection cage 3 and controls the size of the collection assembly 2. Of course, in other embodiments of the present invention, the maximum size and the minimum size of the tapered section 211 can be selected according to practical needs, and are not limited to the above description.

In some embodiments, as shown in fig. 1, the cage 1 has an opening 11 at the upper end thereof, and the animal waste collecting device further comprises a cover body fastened to the upper end of the cage 1. It can be understood that the upper end of the cage body 1 is provided with the opening 11 which can be externally connected with stimulation equipment, such as light stimulation, electrical stimulation and the like, and can collect excrement samples under stimulation state, thereby expanding the application range of the animal excrement collecting device and improving the use satisfaction of users. In addition, the lid of lock on the cage body 1 that adds can avoid the experimental animal to climb out the phenomenon emergence that the cage body 1 influences the experiment effect.

In some embodiments, the number of the cage bodies 1 and the number of the collecting assemblies 2 are multiple, the cage bodies 1 and the collecting assemblies 2 are arranged in a one-to-one correspondence manner, the collecting cage 3 is provided with a plurality of sample bins distributed in a separated manner, each sample bin is provided with one collecting hole 31, and the collecting assemblies 2 and the collecting holes 31 are arranged in a one-to-one correspondence manner. It can be understood that the collecting cage 3 comprises a plurality of sample bins distributed in a separated mode, and the sample bins, the cage bodies 1 and the collecting assemblies 2 are arranged in a one-to-one mode, so that in the experiment process, a plurality of experimental animals can be placed into the collecting cage simultaneously to carry out experiments, the application range of the animal excrement collecting device is expanded, and the use satisfaction degree of a user is improved. In addition, the plurality of sample bins are not communicated with each other, so that the excrement is better prevented from being mixed in the collecting cage 3, and the experimental result is influenced.

In some alternative embodiments, as shown in fig. 1, a plurality of road wheels 6 are provided below the collecting cage 3. Therefore, the whole animal waste collecting device can be moved to any place according to the experiment requirement, and the operation of a user is facilitated. Of course, the number and distribution of the road wheels 6 are not limited, and the number and distribution can be selected according to actual needs.

In some optional embodiments, as shown in fig. 1, the animal waste collecting device further comprises a support 5, the support 5 is connected to the collecting cage 3, the support 5 is provided with a plurality of matching holes, a plurality of cage bodies 1 are connected to the support 5, and the plurality of cage bodies 1 are arranged corresponding to the plurality of matching holes. From this, the cage body 1 is connected and can be guaranteed the stability of the cage body 1 better on support 5, has guaranteed that the experimental animal can be in a relatively stable spatial position to the stability of experiment has been guaranteed and has been gone on.

In some embodiments, the upper end of the housing 21 is connected to the bracket 5, and a plurality of housings 21 are disposed corresponding to the plurality of fitting holes. From this, casing 21 connects and to guarantee casing 21's stability on support 5 betterly, has avoided because casing 21 rocks the phenomenon that leads to excrement and urine to spill animal waste collection device and takes place to guarantee experimental environment's cleanliness factor, promoted user satisfaction.

in some alternative embodiments, the inner wall of the cage 1 is provided with a food trough and a water trough. Therefore, enough foods and water can be placed in the food groove and the water groove at the beginning of the experiment, so that the experiment can be carried out for a long time.
