Description

Technical Field

[0001] This utility model relates to the field of induction box technology, and in particular to a multifunctional rodent anesthesia induction box. Background Technology

[0002] In biomedical experiments and animal research, anesthesia of rodents (such as rats, guinea pigs, and mice) is a common and crucial experimental procedure. Currently, most commercially available rodent anesthesia induction boxes use a fixed spatial structure, which cannot flexibly adjust the internal volume, resulting in significant limitations in practical applications.

[0003] Taking larger animals such as rats and guinea pigs as examples, although existing induction boxes provide sufficient operating space, when handling smaller animals such as mice, the inability to adjust the cavity size forces researchers to fill the entire large cavity with anesthetic, significantly increasing the amount of anesthetic used. This problem not only wastes reagents and increases experimental costs but also poses a potential health risk to operators due to excessive anesthetic volatilization contaminating the laboratory environment. To address these issues, this invention proposes a multifunctional rodent anesthesia induction box. Utility Model Content

[0004] The purpose of this invention is to address the problem that most rodent anesthesia induction boxes commonly used in the market are fixed-space structures, which cannot be adapted to experimental animals of different sizes (such as mice, rats, guinea pigs, etc.). When handling small rodents, this leads to increased experimental costs, pollution of the laboratory environment, and threats to the health of operators. Therefore, this invention proposes a multifunctional rodent anesthesia induction box.

[0005] The technical solution of this utility model is as follows: A multifunctional rodent anesthesia induction box includes a box body with an open top; a sealing assembly installed on the top of the box body, wherein multiple sets of spring latches are provided between the sealing assembly and the box body; a partition disposed in the box body, the partition being used to divide the space in the box body, and two sets of limiting plates being provided on one side of the partition; and two sets of pressing mechanisms, the pressing mechanisms being disposed on the side of the partition away from the limiting plates, the pressing mechanisms being used to push the partition to press tightly against the limiting plates.

[0006] Optionally, the sealing assembly includes a first cover plate disposed above the box body, the first cover plate being located on the side of the partition away from the compression mechanism, a second cover plate being rotatably connected to one side of the first cover plate, multiple sets of spring latches being respectively installed on the sides of the first cover plate and the second cover plate, and rubber strips being installed at the bottom of both the first cover plate and the second cover plate, the rubber strips corresponding to the edge of the box body.

[0007] Optionally, multiple sets of locking blocks are fixedly connected to the bottom of the first cover plate, and a positioning block is provided on the side of the locking block away from the second cover plate. The positioning block is fixedly connected to the outer wall of the box.

[0008] Optionally, a rubber pad is installed on the side of the limiting plate near the partition.

[0009] Optionally, the extrusion mechanism includes a limiting block fixedly connected to the inner wall of the box, a limiting rod slidably connected in the limiting block, and a push plate fixedly connected to one end of the limiting rod near the partition.

[0010] Optionally, a connecting rod is rotatably connected to the side of the push plate away from the partition, and a moving rod is fixedly connected to the end of the connecting rod away from the push plate. A limit ring is slidably connected to one end of the moving rod. The limit ring is arranged parallel to the limit rod and is fixedly connected to the inner wall of the box.

[0011] Optionally, a rotating seat is rotatably connected to the movable rod, a pull rod is fixedly connected to the rotating seat, a sliding sleeve is slidably connected to the pull rod, the sliding sleeve is rotatably connected to the inner wall of the box, and a spring is sleeved on the pull rod, the spring being disposed between the rotating seat and the sliding sleeve.

[0012] Optionally, a first connecting pipe and a second connecting pipe are connected to one side of the box body, and the first connecting pipe and the second connecting pipe are located on the side of the partition away from the limiting plate.

[0013] Optionally, multiple sets of third connecting pipes are provided on both sides of the partition, and the multiple sets of third connecting pipes are installed on the side of the box body, with a sealing plug installed at the end of the third connecting pipe away from the box body.

[0014] Optionally, multiple sets of magnetic clasps are installed inside the box.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention uses an insertable partition in conjunction with a squeezing mechanism to flexibly divide the internal space of the induction box according to the size of the animal (such as rat, guinea pig or mouse). When anesthetizing large animals, the partition can be removed to expand the space, while for small animals, the partition can be used to divide the space into smaller areas, avoiding the filling of a large space with excessive anesthetic, thereby reducing the amount of anesthetic used, reducing experimental costs, and reducing the amount of anesthetic volatilized into the environment, thus reducing the impact on personnel and the environment.

[0017] Furthermore, a mask can be connected via a third connecting tube, which, together with a sealing plug, maintains airtightness. This allows the induction box to be placed directly into the 3D live animal imaging chamber, avoiding the biosafety risks of infecting animal models. It is suitable for biosafety laboratories and infecting animal imaging scenarios. The transparent box is equipped with a magnetic color plate (black / white) to facilitate the observation of fluorescence and autoluminescence phenomena, improving experimental observation efficiency.

[0018] In summary, this invention allows for flexible adjustment of the internal space of the induction box, reducing the amount of anesthetic used, lowering experimental costs, and minimizing the impact of anesthetic volatilization on the environment and personnel. Attached Figure Description

[0034] Example

[0035] like Figure 1 As shown, the present invention proposes a multifunctional rodent-type anesthesia induction box, comprising a box body 1 with an open top, a first connecting pipe 11 and a second connecting pipe 12 connected to one side of the box body 1, the first connecting pipe 11 and the second connecting pipe 12 being disposed on the side of the partition 3 away from the limiting plate 31. The first connecting pipe 11 is used to connect to the anesthesia machine tubing, and the second connecting pipe 12 is used to connect to the filter device.

[0036] For further details, please refer to Figure 2 and Figure 3The aforementioned induction box includes a sealing assembly 2 installed on the top of the box body 1. Multiple sets of spring latches 5 are provided between the sealing assembly 2 and the box body 1, locking the sealing assembly 2 to the top of the box body 1. The sealing assembly 2 includes a first cover plate 21 located above the box body 1, with a second cover plate 22 rotatably connected to one side of the first cover plate 21. Multiple sets of spring latches 5 are respectively installed on the sides of the first cover plate 21 and the second cover plate 22. The first cover plate 21 is located on the side of the partition 3 away from the extrusion mechanism 4, sealing the space of the partition 3 away from the extrusion mechanism 4 after installation. After the second cover plate 22 rotates and fits against the box body 1, it seals the space of the partition 3 near the extrusion mechanism 4. Rubber strips 25 are installed at the bottom of both the first cover plate 21 and the second cover plate 22, corresponding to the edge of the box body 1. The rubber strips 25 improve the sealing performance after the first cover plate 21 and the second cover plate 22 are installed. Multiple sets of locking blocks 23 are fixedly connected to the bottom of the first cover plate 21. A positioning block 24 is provided on the side of the locking block 23 away from the second cover plate 22. The positioning block 24 is fixedly connected to the outer wall of the box body 1. After the first cover plate 21 is installed on the top of the box body 1, the positioning block 24 cooperates with the locking block 23 to limit the first cover plate 21 and prevent the first cover plate 21 from sliding.

[0037] Furthermore, the aforementioned induction box also includes a partition 3 disposed within the box body 1. The partition 3 is used to divide the space within the box body 1. Two sets of limiting plates 31 are disposed on one side of the partition 3. The two sets of limiting plates 31 are symmetrically arranged and fixedly connected to the inner wall of the box body 1 to limit the partition 3. A rubber gasket 32 ​​is installed on the side of the limiting plate 31 near the partition 3 to improve the sealing performance of the partition 3. Multiple sets of third connecting pipes 13 are disposed on both sides of the partition 3. The multiple sets of third connecting pipes 13 are installed on the side of the box body 1. A sealing plug 14 is installed at the end of the third connecting pipe 13 away from the box body 1. A mask can be connected through the third connecting pipe 13. When not in use, the sealing plug 14 is used to ensure airtightness. This function is applied to the 3D live animal imaging chamber, which allows the animal and the anesthesia induction box to be directly placed into the live animal imaging chamber for imaging, avoiding the biosafety risks brought by animal models infected with diseases. It can be applied to biosafety laboratories and imaging of infected animal models.

[0038] Specifically, such as Figures 2 to 4As shown, the aforementioned induction box includes two sets of compression mechanisms 4. The compression mechanism 4 is located on the side of the partition 3 away from the limiting plate 31. The compression mechanism 4 is used to push the partition 3 to press against the limiting plate 31, and at the same time press the rubber gasket 32 ​​to improve the sealing performance. The compression mechanism 4 includes a limiting block 41 fixedly connected to the inner wall of the box body 1. The position of the limiting block 41 is fixed. A limiting rod 42 is slidably connected in the limiting block 41. A push plate 43 is fixedly connected to the end of the limiting rod 42 near the partition 3. The push plate 43 moves smoothly under the limiting action of the limiting block 41 and the limiting rod 42. After moving, the push plate 43 pushes the partition 3 closer to the limiting plate 31. A connecting rod 44 is rotatably connected to the side of the push plate 43 away from the partition 3. A moving rod 45 is fixedly connected to the end of the connecting rod 44 away from the push plate 43. When the moving rod 45 moves, it drives the push plate 43 to move through the connecting rod 44. A limiting ring 46 is slidably connected to one end of the moving rod 45. The limiting ring 46 is parallel to the limiting rod 42 and is fixedly connected to the inner wall of the box 1. The position of the limiting ring 46 is fixed to limit the movement range of the moving rod 45. A rotating seat 47 is rotatably connected to the moving rod 45. When the rotating seat 47 moves, it drives the moving rod 45 to move. A pull rod 48 is fixedly connected to the rotating seat 47. A sliding sleeve 49 is slidably connected to the pull rod 48. The sliding sleeve 49 is rotatably connected to the inner wall of the box 1 and rotates in its original position. Thus, when the pull rod 48 and the rotating seat 47 drive the moving rod 45 to slide in the limiting ring 46, the pull rod 48 slides in the sliding sleeve 49. A spring 410 is fitted onto the pull rod 48. The spring 410 is located between the rotating seat 47 and the sliding sleeve 49. The spring 410 locks the moving rod 45 at both ends of the limiting ring 46, which makes it easy to fix the push plate 43 at a position close to or far from the limiting plate 31.

[0039] Multiple sets of magnetic plates 6 are installed inside the housing 1, which can be used to attach or magnetically attach magnetic color plates to the positions of the magnetic plates 6, and can be removed when not in use. The configured magnetic color plates are black and white, and the housing 1 and sealing component 2 are made of transparent material, which facilitates the observation of fluorescence and self-emission phenomena during live imaging.

[0040] In this embodiment, when anesthetizing large rodents, the spring latch 5 on the side of the second cover 22 is opened, and then the second cover 22 is rotated open. The operator rotates the pull rod 48, causing the pull rod 48 to drive the moving rod 45 away from the partition 3 via the rotating seat 47. The moving rod 45 moves under the limiting action of the limiting ring 46, while the pull rod 48 slides in the sliding sleeve 49, and the spring 410 is compressed. When the moving rod 45 passes the middle position of the limiting ring 46, the pull rod 48 is released, and the spring 410 releases its elastic force, driving the moving rod 45 to the position furthest from the partition 3. At this time, the moving rod 45 drives the push plate 43 to the position furthest from the partition 3 via the connecting rod 44. The push plate 43 moves smoothly under the limiting action of the limiting block 41 and the limiting rod 42. At this time, there is a large distance between the push plate 43 and the limiting plate 31, which facilitates the removal of the partition 3 from the box 1 and the placement of large rodents.

[0041] When anesthetizing small rodents, open the spring lock 5 on the side of the second cover plate 22, then rotate the second cover plate 22 to open it, place the partition 3 between the limiting plate 31 and the push plate 43, rotate the pull rod 48 in the opposite direction to reset it, then place the experimental subject in the box 1, close the second cover plate 22 and lock it with the spring lock 5.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
