For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.
[0043] The embodiments of the present utility model will be described in detail below with reference to the drawings.
[0044] See Figures 1 to 9 , this application provides an animal metabolism cage, which is mainly applicable to test animals such as rabbits. The animal metabolism cage includes: a cage and a chassis 2.
[0045] The cage is openable and closable, and the cage includes a frame 11 and a leaky plate 12, a splash-proof baffle (not shown in the figure), and a drinking area 13 provided on the frame 11.
[0046] A bottom layer 14 for placing the chassis 2 is provided at the lower part of the frame 11.
[0047] The leaky plate 12 is arranged in the frame 11 and above the chassis 2, and a plurality of holes for feces and urine to pass through are distributed on the leaky plate 12.
[0048] The splash-proof baffle is arranged on the lower side surfaces of the frame 11 (such as the left, right, and rear three side surfaces) to prevent urine from splashing out.
[0049] The drinking area 13 is an area for animals to drink water. The drinking area 13 is arranged on one side (such as the front side) of the frame 11. A water supply component (not shown in the figure) is arranged near the drinking area 13, and the water supply component is used to provide drinking water to the drinking area 13. In a specific implementation scenario, the water supply component includes a water bottle, and the water bottle can be fixed on the frame 11 through a steel wire 15, a rubber band 16, etc.
[0050] The chassis 2 is slidably and / or removably disposed on the bottom layer 14 below the sieve plate 12. The chassis 2 has a non-overlapping solid-liquid separation area 21, a urine collection area 22, and a water collection area 24. The solid-liquid separation area 21 and the urine collection area 22 communicate with each other, and the water collection area 24 is independent of the solid-liquid separation area 21 and the urine collection area 22. The chassis 2 is inclined, and the solid-liquid separation area 21 can be located above the urine collection area 22.
[0051] A solid-liquid separation structure for separating feces and urine is provided in the solid-liquid separation area 21. The downward projection of the sieve plate 12 is located within the solid-liquid separation area 21 and does not coincide with the urine collection area 22 and the water collection area 24.
[0052] The urine collection area 22 is used to collect the separated urine. The downward projection of the drinking area 13 is located within the water collection area 24. The middle part on one side of the urine collection area 22 is concave, and the urine can flow centrally to this concave area, making it more convenient to collect.
[0053] The working principle of the animal metabolism cage is as follows:
[0054] The feces and urine produced by the metabolism of the test animals raised in the cage will fall downward onto the solid-liquid separation area 21 of the chassis 2. Under the action of the solid-liquid separation structure, the feces and urine are separated to prevent them from mixing together; the chassis 2 is slidable and / or removable. When collecting feces, the operator does not need to lie on the ground for operation. In addition, since the downward projection of the drinking area 13 is located within the water collection area 24, the water falling from the drinking area 13 will only enter the water collection area 24 of the chassis 2, thereby separating feces, urine, and water.
[0055] The specific implementation manners of the present application will be illustrated by examples below.
[0056] Example 1
[0057] Refer to Figure 1 , in this embodiment, the chassis 2 is inclined, and the inclination direction of the chassis 2 can be changed to adjust the relative height of the solid-liquid separation area 21 and the urine collection area 22 in the vertical direction; for example, when urine collection is not required, the solid-liquid separation area 21 is located below the urine collection area 22. After changing the inclination direction of the chassis 2, the solid-liquid separation area 21 is located above the urine collection area 22, enabling the urine to gather in the urine collection area 22, facilitating collection with a sampling tool and preventing feces and urine from mixing together.
[0058] In this embodiment, movable rods 23 are movably disposed between the chassis 2 and the bottom layer 14. The chassis 2 is placed on the movable rods 23, and the positions of the movable rods 23 are adjustable to facilitate changing the inclination direction of the chassis 2 (the dimensions of each direction of the bottom layer 14 can be larger than the dimensions of the chassis 2, and the chassis 2 does not need to be inclined at too large an angle).
[0059] Example 2
[0060] In the prior art, the freestanding metabolic box needs to be manually disassembled, cleaned, and disinfected, resulting in high labor costs. After the freestanding metabolic box has been used for a long time, the connection between it and the cage is prone to damage, and there have been cases where the metabolic box has fallen off, affecting urine collection.
[0061] See Figure 1 、 Figure 5 and Figure 6 To solve the above problems, in this embodiment, one side of the urine collection area 22 bulges outwards to form an integrated metabolic box 27, and the integrated metabolic box 27 can be in the shape of a cuboid, arc, etc. The integrated metabolic box 27 is used for centralized urine collection for easy collection. Compared with the freestanding metabolic box, there is no need to additionally consider disassembly and assembly problems, and it is not easy to fall off (the integrated metabolic box 27 is integrally connected to the chassis 2). In addition, the integrated metabolic box 27 can be cleaned and disinfected together with the chassis 2 to reduce labor costs.
[0062] Example 3
[0063] See Figures 1 to 4 In this embodiment, the solid-liquid separation structure includes a plurality of protrusions 28 arranged at intervals, and a groove 29 is formed between any two adjacent protrusions 28, and one end of the groove 29 is connected to the urine collection area 22.
[0064] See Figure 1 、 Figure 7 and Figure 8 In this embodiment, the shape of the protrusion 28 is arc-shaped or hemispherical. The plurality of protrusions 28 are arranged in a rectangular array on the chassis 2, and the height of the row of protrusions 28 closest to the urine collection area 22 is greater than that of the other protrusions 28 to prevent feces from overflowing into the urine collection area 22.
[0065] Example 4
[0066] See Figures 7 to 8 In this embodiment, a cushion block 32 is provided at the bottom of the chassis 2, and the cushion block 32 is located at the lower rear of the solid-liquid separation area 21, so that the upper side of the chassis 2 is in an inclined state where the solid-liquid separation area 21 is higher than the urine collection area 22, thereby facilitating the aggregation of urine in the urine collection area 22.
[0067] In this embodiment, a notch 33 is provided on the upper side of the chassis 2, and the notch 33 communicates with the solid-liquid separation area 21. The solid-liquid separation area 21 is located between the notch 33 and the urine collection area 22. In this way, both the overall weight of the chassis 2 is reduced, and the drainage operation after cleaning the chassis 2 is facilitated.
[0068] Example 5
[0069] In this embodiment, the protrusion 28 is strip-shaped. AsFigure 3 As shown, the length direction of the protrusion 28 is perpendicular to the length direction of the chassis 2, or the length direction of the protrusion 28 intersects the length direction of the chassis 2 obliquely.
[0070] The cross-section of the protrusion 28 is rectangular.
[0071] After feces and urine fall on the protrusion 28, the feces are supported by the protrusion 28 and suspended, thus realizing the separation of feces and urine.
[0072] Embodiment 6
[0073] See Figure 2 , different from Embodiment 5, the cross-section of the protrusion 28 is triangular. At this time, the width of the groove 29 gradually decreases from top to bottom. After feces fall into the groove 29, they are in a suspended state, naturally separating feces and urine.
[0074] Further, along the length direction of the protrusion 28, the closer to the urine collection area 22, the smaller the width of the groove 29, so as to prevent the feces in the groove 29 from rolling or sliding into the urine collection area 22.
[0075] Embodiment 7
[0076] See Figure 4 , in this embodiment, the solid-liquid separation structure includes a number of wire meshes 31 or filter plates and other partition members for separating solids and liquids.
[0077] Embodiment 8
[0078] See Figure 9 , in this embodiment, a roller 34 is provided in the middle of the side surface of the chassis 2. The roller 34 can roll on the bottom layer 14, and the chassis 2 can rotate around the axis of the roller 34, thus facilitating the change of the inclination direction of the chassis 2.
[0079] Further, an adjustable member that can move longitudinally is provided between the bottom layer 14 and the chassis 2. The adjustable member is located directly below the urine collection area 22. Moving the adjustable member upward can make the chassis 2 in an inclined state where the solid-liquid separation area 21 is below the urine collection area 22 (equivalent to raising one end); moving the adjustable member downward can make the chassis 2 in an inclined state where the urine collection area 22 is below the solid-liquid separation area 21. The adjustable member is, for example, a plug that can be inserted into multiple positions of the frame 11.
[0080] Further, anti-disengagement stop posts 35 are longitudinally provided on the bottom layer 14, and a stop bar 36 that cooperates with the anti-disengagement stop posts 35 is transversely provided on the chassis 2. When the chassis 2 is pulled outwards, due to the blocking of the anti-disengagement stop posts 35 on the stop bar 36, the rolling stroke of the chassis 2 is limited and the anti-disengagement function is achieved.
[0081] In particular, Embodiments 1 to 8 can be applied not only to rabbits but also to dogs, pigs, and monkeys.
[0082] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Without conflict, the embodiments of this application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
