Description

Technical Field

[0001] The utility model relates to the technical field of cage fixtures, in particular to an IVC self-controlled temperature cage fixture suitable for nude mice. Background Art

[0002] In the modern world, humans spend most of their time at temperatures close to thermoneutrality, while mice, the most commonly used experimental animals for exploring human diseases, live in environmental facilities far below their thermoneutral temperature. Always being in an environment below the thermoneutral temperature will have an impact on the behavior, physiology, etc. of mice. Such an environmental temperature setting obviously not only reduces the welfare of mice but also affects the effectiveness of scientific research carried out using them as human surrogates.

[0003] Fully, consistently, and thoroughly solving the problem of too low temperature in mouse facilities faces the following two obstacles. First, raising the facility temperature from 22 °C to 30 °C will face huge investment and increased operating costs (requiring more heating equipment and energy expenses); second, a room temperature of 30 °C is quite challenging for the staff in animal facilities and may even be dangerous in some cases. The IVC breeding mode basically isolates humans and animals, providing a premise for independent and differentiated control of room temperature and animal cage temperature. Therefore, we choose to find a breakthrough in the design of the cage fixture, and for this purpose, an IVC self-controlled temperature cage fixture suitable for nude mice is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems put forward in the background art, and an IVC self-controlled temperature cage fixture suitable for nude mice is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An IVC self-controlled temperature cage fixture suitable for nude mice, comprising an IVC cage rack and cage boxes. A plurality of evenly distributed cage box positions are arranged inside the IVC cage rack, and a first induction coil and an induction coil top plate are arranged at the air outlet on one side of each of the plurality of cage box positions; the cage boxes can be inserted into the inside of the cage box positions, an induction coil access end is arranged on one side of the cage box, and second induction coils are arranged on the inner walls of the four sides and the bottom inner wall of the cage box.

[0007] Preferably, a blocking partition is arranged at the center inside the cage box.

[0008] Preferably, universal wheels are arranged at the four corners of the bottom of the IVC cage rack.

[0009] Preferably, the cage box adopts a PSU integrally formed box body.

[0010] Preferably, both the first induction coil and the second induction coil are wireless power transfer coils.

[0011] Preferably, a temperature sensor is built into the exhaust end of the IVC cage frame.

[0012] Compared with the prior art, the present utility model provides an IVC self-controlled temperature cage for nude mice, having the following beneficial effects:

[0013] 1. The IVC self-controlled temperature cage for nude mice can meet the production and growth temperature requirements of different strains and categories of animals without changing the existing facility production conditions, avoiding large-scale renovation and replacement of equipment, and reducing the difficulty and cost brought by the changing requirements of production temperature.

[0014] 2. The IVC self-controlled temperature cage for nude mice uses the electromagnetic induction wireless power transfer mode to avoid the exposure of wires and electrodes. The all-buried, embedded or coated process greatly improves the anti-wear and corrosion resistance of the cage. The cage boxes are plug-and-play, and almost no changes to the existing production process are required, making the use process more convenient and safe.

[0015] 3. The IVC self-controlled temperature cage for nude mice uses a temperature control sensor at the exhaust end to more directly and accurately achieve temperature control and compensation. The temperature difference obtained by the temperature sensor is used to reversely control the power supply of the cage, thereby realizing the control of cage box heating, and making timely auxiliary heat compensation for the temperature difference of the supply air, so as to make the temperature environment in the cage basically constant.

[0016] 4. The successful development of the new cage for the IVC self-controlled temperature cage for nude mice greatly promotes the refined, scientific and intelligent management of experimental animal breeding, provides a successful example for the IVC feeding mode of experimental animals, and plays a positive role in promoting the progress and development of the experimental animal industry.

[0017] Parts not involved in this device are the same as those in the prior art or can be implemented using the prior art. The present utility model performs secondary auxiliary heating of the cage under the condition of an unchanged existing fresh air system, so as to effectively improve and control the internal environment temperature of the cage under a set of fresh air systems, so as to achieve the applicability under the existing facility hardware conditions.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
