Description

Technical Field

[0001] The utility model belongs to the field of experimental equipment, and in particular relates to a mouse excrement collection cup. Background Art

[0002] Mice are the preferred model animals for replicating and studying animal models of human diseases without special reasons due to their short reproductive cycle, easy access to experimental animals, good biological stability, and easy replication of disease models. They are often used in scientific research and teaching experiments. Generally, in drug toxicity tests and studies of various metabolic diseases, it is necessary to closely monitor the food intake, water intake, and excretion of experimental animals, and to collect and separate the excrement of the collected experimental animals to obtain accurate excretion volume or collect fresh and uncontaminated urine and feces from the experiment for intestinal microbial analysis and various biochemical indicators. At this time, test instruments that can accurately collect, separate, and ensure the non-contamination of the sample's excrement of experimental animals are needed.

[0003] For example, Chinese patent (CN202022998235.8) discloses a feces collection bottle for rats and mice metabolism cage. The feces collection bottle for rats and mice metabolism cage of the utility model includes an upper bottle body, a lower bottle body and a filter. The bottom of the upper bottle body is provided with an opening, the top of the lower bottle body is provided with an opening, the top of the lower bottle body is detachably connected to the bottom of the upper bottle body, and the filter is arranged in the upper bottle body or the lower bottle body. The feces collection bottle for rats and mice metabolism cage can separate the collected feces from the feed residue to obtain a single feces of rats and mice; the bottle body and the bottle bottom are combined into a bottle body by a detachable connection, and the bottle body and the bottle bottom can be disassembled to conveniently take out the collected feces of rats and mice, and it is also convenient to clean the feces collection bottle for rats and mice metabolism cage after the experiment.

[0004] However, the above device still has certain problems.

[0005] 1. The structure is relatively complex and difficult to disinfect, which increases the dead corners and hidden areas inside the urine collection bottle, which are prone to breed bacteria and pathogens, increasing the risk of cross infection.

[0006] 2. Mice tend to trample and excrete feces and urine, which can easily lead to inaccurate results of subsequent microbial testing.

[0007] 3. It is not easy to pick up feces at any time. If urine is mixed with feces, the quality of urine may be contaminated, affecting the accuracy of subsequent experimental results.

[0008] 4. Urine evaporates easily upwards. The evaporation of urine will lead to a decrease in the water content in it, which will increase the concentration of other components in urine, thus affecting the accuracy of the experimental results.

[0009] 5. It is inconvenient to take out the mice and they can easily escape. Summary of the invention

[0037] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0038] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0039] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0041] like Figure 1 and Figure 2 The mouse excrement collection cup shown includes an outer cup 1, a urine suction straw 11 and feces tweezers 12. An internal thread 13 is provided on the inner wall of the lower end of the outer cup 1. A threaded ring 14 is threadedly connected to the bottom of the outer cup 1 through the internal thread 13. A collecting base 9 is fixedly connected to the bottom of the threaded ring 14. A detachable inner cup 5 is arranged inside the outer cup 1. The outer edge of the upper end of the detachable inner cup 5 is overlapped with the upper end of the outer cup 1. An hourglass-shaped urine collector 7 is fixedly connected inside the outer cup 1 and below the detachable inner cup 5. A primary mesh sheet 6 is fixedly installed at the bottom of the detachable inner cup 5, and a secondary mesh sheet 8 is fixedly installed above the hourglass-shaped urine collector 7.

[0042] Please refer to Figure 1 As shown, a cup cover 2 is arranged above the outer cup 1, and a limiting block 4 is fixedly connected to the bottom edge of the cup cover 2. The shape of the limiting block 4 fits the upper edge of the outer cup 1, so that the cup cover 2 is not easy to shake when it is covered on the outer cup 1.

[0043] Please refer to Figure 1 As shown, a ventilation hole 3 is formed through the upper surface of the cup cover 2, and the ventilation hole 3 can keep air circulation for the mouse in the cup, and the cover can be opened to take out the mouse at any time.

[0044] Please refer to Figure 1 As shown, a handle 15 is fixedly connected to the center of the top of the cup cover 2. The setting of the handle 15 can provide a force point to facilitate the taking of the cup cover 2.

[0045] Please refer to Figure 2 As shown, a conical portion 10 is provided inside the collecting base 9 . The design of the conical portion 10 can concentrate urine in the center of the collecting base 9 , making it easier for the urine suction straw 11 to suck urine.

[0046] Please refer to Figure 1 As shown, the outer cup 1 and the detachable inner cup 5 are both made of fully transparent acrylic material. The height of the outer cup 1 is greater than 20 cm and the material is heavy, so it is not easy for mice to knock over the device, so that the defecation of mice can be observed at any time.

[0047] Please refer to Figure 2 As shown, the aperture of the primary mesh sheet 6 is one centimeter. The aperture setting of one centimeter allows the feces of mice to fall onto the secondary mesh sheet 8, thereby preventing the mice from trampling on the feces.

[0048] Please refer to Figure 2 As shown, the aperture of the secondary mesh sheet 8 is 0.5 cm, and the aperture of 0.5 cm can prevent mouse feces from falling into the collecting base 9, causing inaccurate urine detection results.

[0049] Please refer to Figure 2 As shown, the hourglass-like urine collector 7 is in a simulated cone shape with wide ends and a narrow middle, and the detachable inner cup 5 is arranged with a wide bottom and a narrow mouth. The hourglass-like urine collector 7 is in a simulated cone shape with wide ends and a narrow middle, which can prevent part of the urine from evaporating and being lost, resulting in insufficient amount of collected urine for subsequent experimental analysis, thereby affecting the reliability of the experimental results, and the detachable inner cup 5 with a wide bottom and a narrow mouth design can prevent mice from escaping.

[0050] Please refer to Figure 4 As shown, the urine suction straw 11 includes a rubber nipple and a pointed glass tube, and the rubber nipple is fixedly installed on the top of the pointed glass tube. The urine suction straw 11 is a prior art and will not be elaborated in detail here.

[0051] Working principle: During installation, first install the secondary mesh sheet 8 on top of the hourglass-shaped urine collector 7, then screw the collecting base 9 to the bottom of the outer cup 1 through the internal thread 13, then install the primary mesh sheet 6 on the bottom of the detachable inner cup 5 and place the detachable inner cup 5 inside the outer cup 1, then place the mouse inside the detachable inner cup 5, and then cover the cup cover 2 on top of the outer cup 1. After waiting for the urine collection to be completed, open the cup cover 2 and take out the detachable inner cup 5. You can use the urine suction straw 11 to absorb urine, and use the feces tweezers 12 to clamp the mouse feces on the secondary mesh sheet 8.

[0052] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
