Description

Marmoset hanging weighing device Technical Field

[0001] The present application relates to the field of medical testing technology, and in particular to a marmoset hanging weighing device. Background Art

[0002] Marmosets are a species of primate mammal in the family Marmoset. Their reproduction is non-seasonal, with a gestation period of 130 to 160 days. Each litter typically produces two pups, which are nursed by both parents, who alternately carry or hold the pups on their backs. During pregnancy, a marmoset's weight reflects the growth of the embryo within the mother's body. During the second trimester, the fetus experiences a rapid increase in weight, which stabilizes for a period before giving birth. In conventional laboratory settings, marmosets are typically caged. To weigh them, a veterinarian removes the animal from its cage, straps it to an electronic scale, and manually measures the weight, recording the data in a logbook. This manual process is time-consuming and, due to the timid nature of marmosets, can startle the animal or cause it to escape. Due to the risks and time costs of measuring weight, frequent and continuous weight measurements are often not feasible. Manual measurements are typically performed once or twice a week, making them unsuitable for the rapid weight changes experienced during pregnancy.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0019] FIG1 is a schematic structural diagram of a marmoset hanging weighing device according to an embodiment of the present application. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0022] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0024] 1 , an embodiment of the present application provides a marmoset hanging weighing device, comprising a housing 1 and a controller 2 .

[0025] The box body 1 is a rectangular parallelepiped frame structure made of polycarbonate, acrylic, aluminum alloy or stainless steel. An entrance 11 for the marmosets to enter and exit is provided on the left side wall of the box body 1. A weighing cabin 12 is defined in the box body 1, and a weighing sensor 13 is provided at the bottom of the weighing cabin 12. In order to allow the marmosets 4 to enter the weighing cabin 12 independently without human supervision, a food placement area 14 is provided on the right side of the weighing sensor 13, and a feeding port (not shown) is provided on the right side wall of the box body 1. Thus, the marmosets 4 can be encouraged to enter the weighing cabin 12 by feeding them food, thereby achieving the purpose of attracting and training the marmosets 4 to perform autonomous weighing. It should be noted that the method of attracting the marmosets 4 to enter can also be replaced by other objects that the marmosets 4 are interested in, which is not limited here.

[0026] [Corrected 17.05.2024 in accordance with Rule 91] The front and rear side walls of the housing 1 are each provided with connection holes 16. One end of a bolt passes through the connection hole 16 and connects to the monkey cage observation window. This allows the housing 1 to be securely mounted on the monkey cage observation window.

[0027] In order to facilitate the staff to clean the interior of the box body 1, a window (not shown in the figure) for the staff to enter and exit is also opened on the side wall of the box body 1.

[0028] A control box 3 is mounted on the upper surface of the housing 1. This box houses a controller 2, a power adapter, a heat sink, and a display screen. The controller 2 utilizes an x86-based microcomputer integrated with an Arduino. The microcomputer processes data within the device, while the Arduino board collects and converts the signals fed back by the weighing sensor 13 into weight data. The heat sink dissipates heat. The display screen is connected to the controller 21 and displays the weight data, facilitating intuitive viewing. This allows for continuous weight data collection each time a marmoset 4 enters the weighing chamber 12. As the number of entries increases, multiple sets of data can be obtained daily.

[0029] A panoramic camera 15 is provided on the top of the weighing cabin 12. This allows the marmoset 4 to be photographed throughout the entire enclosure 1. If an unreasonable weight test result is detected, the situation inside the cage can be traced back by querying the monitoring screen using the timestamp of the weight value.

[0030] The working principle of the marmoset 4-hanging weighing device in the embodiment of the present application is as follows:

[0031] Food or water is placed in advance through the feeding port into the food storage area 14. Attracted by the food or water, the marmoset 4 to be tested enters the weighing chamber 12. The weighing sensor 13 in the weighing chamber 12 detects a set of weight data. The controller 2 reads and analyzes the received data, then transmits it to the display for display, thus obtaining a continuous set of weight data. As the number of marmosets 4 entering the cage increases, multiple sets of data can be obtained daily. If the weight test yields an unreasonable result, the cage's condition can be traced back by querying the monitoring screen using the timestamp of the weight value.

[0032] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
