DETAILED DESCRIPTION
[0024] The technical solutions in the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0025] Reference Figs. 1-3 The present application provides a trough for metabolic cage, which comprises a trough body and a collecting container detachably installed at the bottom of the trough body.
[0026] The trough body is detachably installed at the feeding port position of the metabolic cage.
[0027] The first side wall of the trough body facing and close to the feeding port is provided with a hollow structure for the animal to eat.
[0028] The first side wall and the feeding port have a gap, and the bottom of the gap is a hollow structure so that food residues fall into the collecting container.
[0029] In the embodiment of the present application, generally speaking, the interface for installing the trough at the feeding port of the metabolic cage is a plug-in buckle mode. The connecting buckle for detachable connection of the trough body of the present application is matched with the interface of the metabolic cage, and details are not described herein. It should be noted that the material of the trough body can be stainless steel, which can effectively prevent the animal from gnawing and ensure food safety. The collecting container can be made of plastic material, which can reduce the cost to a certain extent.
[0030] The trough for metabolic cage provided in the embodiment of the present application is especially suitable for application in mouse metabolic cages.
[0031] In the embodiment of the utility model, the food is located in the trough body, the animal is separated from the food by the first side wall, the animal eats at the hollow structure of the first side wall, and the food cannot be carried into the metabolic cage, in addition, since the first side wall and the feeding opening (the side wall of the metabolic cage) have a gap, and the bottom of the gap is a hollow structure, the food residues generated when the animal eats fall through the hollow bottom of the gap to the outside of the metabolic cage (such as falling into the collection container), but not into the metabolic cage, thereby effectively avoiding the food being collected with feces and / or urine, improving the accuracy of sample separation, purification and further detection, and ensuring the accuracy of the experimental results. In addition, after the collection container collects the food residues, the food residues can be weighed, thereby facilitating the calculation of the actual food weight consumed by the animal.
[0032] In a specific embodiment, the size of the hollow structure of the first side wall is smaller than the size of the food. Preferably, the first side wall is formed as a fence structure, and the distance between adjacent longitudinal bars is smaller than the size of the food. Understandably, in this specific embodiment, in order to prevent the food from being carried into the metabolic cage by the animal, the size of the hollow structure is set to be smaller than the size of the food, so that the food cannot be taken out through the hollow part, and the animal can eat the food at the hollow position. After the food is smaller than the hollow position, the remaining food is either eaten directly by the animal or falls through the hollow structure at the bottom of the gap into the collection container, thereby greatly reducing the possibility of being carried into the metabolic cage by the animal. It should be noted that the first side wall is preferably provided as an inclined surface, and the inclined direction is gradually away from the side of the metabolic cage from the bottom to the top, and the angle between the first side wall and the vertical direction is, for example, 0-20°, which is more convenient for the animal to eat.
[0033] In a specific embodiment, the trough body has a second side wall opposite to the first side wall, and the second side wall has an inclined surface forming an angle with the first side wall. Preferably, the angle between the inclined surface and the first side wall is an acute angle. More preferably, the top of the inclined surface has a vertical surface formed by bending, and the vertical surface and the first side wall form a food taking and placing opening. Understandably, the inclined surface of the second side wall forms an angle with the first side wall, which is more convenient for the food to move towards the first side wall under the action of gravity, thereby facilitating the animal to access the food. When the angle is an acute angle, it is more convenient for the food to move under the action of gravity and for the animal to eat.
[0034] In a specific embodiment, the second side wall is formed as a fence structure, and the distance between adjacent longitudinal bars is smaller than the size of the food. Understandably, the distance between adjacent longitudinal bars is smaller than the size of the food, in order to prevent the food from falling between the gaps of the fence into the collection container.
[0035] In a specific embodiment, the trough body has a third side wall and a fourth side wall which are perpendicular to the first side wall; the first side wall, the second side wall, the third side wall and the fourth side wall enclose the trough body. Understandably, the third side wall and the fourth side wall can be hollow structures or non-hollow structures. The trough body enclosed by the first side wall, the second side wall, the third side wall and the fourth side wall is used for containing food; the top of the first side wall, the vertical top of the second side wall, the top of the third side wall and the top of the fourth side wall enclose a food access opening, which facilitates the storage or removal of food into or from the trough body.
[0036] In a specific embodiment, the bottom of the third side wall and the fourth side wall is bent to form a sliding groove, the top of the collection container is formed with a sliding block which matches the sliding groove, and the collection container is detachably installed at the bottom of the trough body through the cooperation of the sliding block and the sliding groove.
[0037] The above merely describes the preferred embodiments of the present application and is not intended to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
