Abstract
Description
Technical Field
[0001] The present application relates to the technical field of animal experimental instruments, and in particular to a rat weighing cup capable of separating excrement. Background Art
[0002] In animal experiments, the weight change of experimental animals is one of the most basic data. However, there are currently no special tools for weighing small animals. For example, when weighing rats, the beaker is generally placed on an electronic balance first, the reading of the electronic balance is reset to zero, and then the rat is placed in the beaker for weighing. However, because rats are active, they will constantly run, jump, grab the mouth of the cup, and probe upward during the weighing process. Sometimes they will even knock over the beaker, which affects the accuracy of the experimental results on the one hand, and is time-consuming and has a high risk of being bitten on the other hand. In addition, the weighing stimulation can cause urinary incontinence or fecal incontinence in rats, which can easily contaminate the weighing equipment. The excrement will be concentrated at the bottom of the beaker, which will interfere with intestinal flora-related research experiments and cause mutual contamination of flora between rats in different groups, especially fecal microbiota transplant experiments, which will affect the experimental results. In addition, it is inconvenient to clean after weighing, and the bottom of the beaker is difficult to clean. Utility Model Content

[0031] Reference Figures 1 to 5 An embodiment of the present application provides a rat weighing cup capable of separating excrement, comprising a cup body 1 and a flexible mesh cover 2 arranged in the cup body 1, a rat support frame 3 and an excrement collection drawer 4.
[0032] The rat support frame 3 is connected to the inner wall of the cup body 1, and the excrement collection drawer 4 is connected to the cup body 1 and is located below the rat support frame 3. The flexible mesh cover 2 is detachably connected to the inner wall of the cup body 1 and is located above the rat support frame 3. During weighing, the flexible mesh cover 2 can cover the back of the rat and make the rat lie on the rat support frame 3.
[0033] The cup body 1 is cylindrical with two ends open and is made of transparent PP plastic material. In this way, it not only has the advantages of low cost, strong and shatterproof, and low cost, but also can observe the state and activity of rats at any time. The inner diameter of the cup body 1 is 15 cm and the height is 20 cm. Since the size of the mouth of the cup body 1 is large, it can prevent rats from grabbing the cup mouth and resisting entry.
[0034] The rat support frame 3 is used to support rats. The rat support frame 3 is connected to the inner wall of the cup body 1 and is located 5 cm away from the bottom of the cup. The rat support frame 3 is made of a square grid made of stainless steel. The aperture of the square grid is 2.5 cm×2.5 cm, which can ensure that excrement can pass smoothly. In this way, it is not only corrosion-resistant, but also easy to clean.
[0035] The flexible net cover 2 is connected to the inner wall of the cup body 1 through a buckle assembly. The buckle assembly includes a plurality of buckles 5, for example, two buckles 5, uniformly distributed along the circumference on the inner wall of the cup body 1. The buckle 5 is a protrusion, the outer end of the protrusion is connected to the inner wall of the cup body 1, the inner end is engaged with the upper surface of the flexible net cover 2, and the inner end of the protrusion is inclined and extends downward, so that the flexible net cover 2 can be prevented from being lifted up by the rat, and the installation position of the flexible net cover 2 can be adjusted easily.
[0036] In order to be able to weigh rats of different sizes, the buckle components in the embodiment of the present application are multiple groups, for example, four groups. The multiple groups of buckle components are evenly distributed on the inner wall of the cup body 1 along the axial direction, and the distance between the buckle component located at the bottom and the rat support frame 3 is 4 cm. In this way, it can be ensured that when the rat is weighed, the flexible mesh cover 2 covers the back of the rat and makes the rat lie on the rat support frame 3. In this way, the activities of rats of different sizes can be restricted.
[0037] The flexible net cover 2 is a round soft stainless steel net with a diameter of 15 cm. The stainless steel material makes it have good corrosion resistance. The periphery of the soft net is reinforced with iron wire. The hardness of the soft net should be able to prevent the rat from resisting upwards. It also has a certain flexibility, allowing the operator to place the soft net in the cup body 1 and fix it with the protruding buckle 5 on the cup wall. When the weighing is completed, the operator can lift the middle of the soft net upwards, quickly release it from the buckle 5, and then perform the mouse replacement operation. In order to facilitate the lifting of the flexible net cover 2, a first handle 6 is provided in the middle of the upper surface of the flexible net cover 2.
[0038] The bottom of the side of the cup body 1 is provided with a mounting opening, which is a semi-cylindrical notch with a height of 5 cm, that is, half of the side of the bottom of the cup body is cut off in the circumferential direction. A slide is provided at the bottom of the cup body 1. The excrement collection drawer 4 is cylindrical with an opening facing upward, and its size is adapted to the size of the mounting opening, with a height of 4.5 cm and an outer diameter of 15 cm. Thus, the excrement collection drawer 4 can be pulled apart laterally. In order to facilitate replacement and cleaning, a second handle 7 is provided on the outside of the excrement collection drawer 4. In addition, the excrement collection drawer 4 is also made of PP plastic material, which has the advantages of low cost, strong and drop-resistant, and low cost.
[0039] The usage process of the embodiment of the present application is as follows:
[0040] Before use, first push the excrement collection drawer 4 into the installation opening of the cup body 1, place the flexible mesh cover 2 in the cup body 1, then place the embodiment of the present application on an electronic balance, and return the reading of the electronic balance to zero.
[0041] Then, take out the flexible mesh cover 2, put the rat to be weighed into the cup body 1, put the flexible mesh cover 2 into the cup body 1, and gently push the flexible mesh cover 2 downward to the buckle 5 at a suitable height according to the body size of the rat, to ensure that the rat cannot move freely and lie on the rat support frame 3. Note that the rat should not be harmed during this process. After the weighing is completed, take out the flexible mesh cover 2, take out the rat and put it back into the cage, and weigh the next rat.
[0042] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
