Description

Technical Field

[0001] This utility model relates to the technical field of experimental devices for placing experimental animals with mechanical pain thresholds in animals, and in particular to a basic version of an experimental device for placing experimental animals with mechanical pain thresholds in rats and mice. Background Technology

[0002] Pain threshold refers to the minimum stimulus intensity required to elicit a pain response. In animal medical experiments, the determination of the mechanical pressure pain threshold in mice is a common method. This experiment typically involves placing the mouse in a transparent cage with a mesh bottom, exposing its paws. Then, a series of Von Frey fibers of varying calibrated weights are used to vertically stimulate the plantar region of the mouse's hind paw. A clear paw withdrawal action is observed as an indicator of a pain response, and the corresponding fiber pressure value is recorded. While traditional animal behavioral experiment placement devices have achieved a high degree of standardization and manufacturing precision, their purchase cost is usually quite high. These devices are often mass-produced using specialized molds, resulting in a large initial investment, which may pose a significant financial burden for laboratories or research teams with limited budgets. Furthermore, such devices are often physically fixed and uniform in size, lacking necessary flexibility. Therefore, those skilled in the art provide a basic version of a mechanical pain threshold placement device for mice and rats to address the problems mentioned in the background. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a basic version of a mechanical pain threshold experimental animal placement device for rats and mice.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A basic mechanical pain threshold testing animal placement device for rats and mice includes a platform, a support frame, and a mouse cage. The platform is placed on the support frame, and the mouse cage is placed on the platform. The three parts are combined to form the basic mechanical pain threshold testing animal placement device for rats and mice.

[0005] As a further embodiment of this invention, the platform includes a load-bearing mesh mounted on a support frame, and a contact mesh is provided on the top of the load-bearing mesh. Both the load-bearing mesh and the contact mesh are made of metal mesh.

[0006] As a further improvement of this utility model, the mouse cage is made of transparent acrylic material, and the diameter of the mouse cage is adapted to the size of the platform.

[0007] As a further embodiment of this utility model, the support frame has equidistant limit holes on its front side, and limit bolts are inserted into the inside of the limit holes.

[0008] As a further embodiment of this utility model, the surface of the limiting bolt is slidably connected with a slot block, and the top of the slot block overlaps the bottom of the platform.

[0009] As a further embodiment of this utility model, a fixing rod is fixedly connected to one side of the support frame, and universal wheels are threadedly connected to both sides of the bottom of the fixing rod.

[0010] As a further embodiment of this utility model, a connector is fixedly connected to the other side of the support frame, and a reinforcing rod is inserted into the inside of the connector.

[0011] As a further embodiment of this utility model, the outer surface of the support frame is covered with an anti-oxidation film to increase anti-oxidation, and the interior of the universal wheel is provided with a brake pad.

[0012] The advantage of this invention over traditional animal behavior experiment placement devices is: 1. By setting up the platform and the cage, when personnel need to assemble the platform, they can use wire to connect and assemble the load-bearing net and the contact net. Then, the cage is made of transparent acrylic sheet, which greatly reduces the cost and technical complexity of equipment preparation and significantly lowers the equipment threshold for behavioral experiments on mice and rats. This device is especially suitable for laboratories with limited budgets, research teams, or occasions that require large-scale preliminary behavioral screening, providing a reliable, easy-to-operate, and reusable solution for conducting mechanical pain threshold detection and related experiments.

[0013] 2. By using a support frame, platform, and limiting bolts, when staff need to assemble the support frame, they can place the platform on the surface of the support frame, then use the slotted blocks to place it on the outer surface of the support frame, and use the limiting bolts to insert it into the limiting holes. This allows for quick installation of the platform, facilitating greater flexibility and personalized adaptation of the equipment. It also allows researchers to quickly adjust or replace corresponding modules according to different experimental goals and procedures, greatly improving the reusability and experimental efficiency of the equipment, and enhancing the accuracy and reliability of threshold detection results.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0017] Reference Figures 1-4 A basic mechanical pain threshold testing animal placement device for rats and mice includes a platform 1, a support frame 2, and a mouse cage 3. The platform 1 is placed on the support frame 2, and the mouse cage 3 is placed on the platform 1. The three parts together constitute the basic mechanical pain threshold testing animal placement device for rats and mice. When personnel need to assemble the support frame 2 and the platform 1, they can use wire to tie the load-bearing net 11 and the contact net 12 together. The wire is fixed in a star-shaped pattern at the bottom of the load-bearing net 11. Then, when assembling the platform 1, the personnel can place the slot block 5 on the outer surface of the support frame 2 and use the limit bolt 4 to insert it into the limit hole to fix the platform 1. Then, the personnel can place the rat cage 3 on the top of the contact net 12 and place it at equal intervals. Next, the personnel can use the casters 7 to move the support frame 2, which facilitates the movement of the support frame 2. The internal brake pads can be used to fix the support frame 2.

[0018] In this utility model, the platform 1 includes a load-bearing mesh 11 installed on the support frame 2. The load-bearing mesh 11 is made of metal mesh. A contact mesh 12 is provided on the top of the load-bearing mesh 11. The two are divided into upper and lower layers. The lower layer uses a metal mesh with a larger aperture and higher mechanical strength as the load-bearing layer, while the upper layer is a contact mesh with a smaller aperture and lower mechanical strength. Limiting holes are equidistantly opened on the front of the support frame 2. Limiting bolts 4 are inserted into the inside of the limiting holes. A slot block 5 is slidably connected to the surface of the limiting bolt 4. The top of the slot block 5 overlaps the bottom of the platform 1.

[0019] With the setting of limit bolt 4 and slot block 5, when personnel need to support the support frame 2, they can directly place the slot block 5 on the outer surface of the support frame 2 and use the limit bolt 4 to insert it into the limit hole on the surface of the support frame 2, thereby facilitating the assembly of the platform 1.

[0020] In particular, the rat cage 3 is made of transparent acrylic material, and the diameter of the rat cage 3 is compatible with the size of the contact wire 12.

[0021] By using the mouse cage 3, which is made of transparent acrylic material, the cost of manufacturing the mouse cage 3 is reduced.

[0022] In particular, a fixing rod 6 is fixedly connected to one side of the support frame 2, and universal wheels 7 are threadedly connected to both sides of the bottom of the fixing rod 6. A connector 8 is fixedly connected to the other side of the support frame 2, and a reinforcing rod 9 is inserted into the inside of the connector 8. An anti-oxidation film for increasing anti-oxidation is attached to the outer surface of the support frame 2, and a brake pad is installed inside the universal wheel 7. With the universal wheels 7 and brake pads, when personnel need to move the support frame 2, they can use the universal wheels 7 to move the support frame 2 to a suitable position and use the brake pads to brake the universal wheels 7, thus facilitating the movement of the support frame 2.

[0023] It should be noted that: the platform 1, the support frame 2, and the mouse cage 3 are the core components of this basic version of the mechanical pain threshold experimental animal placement device for rats and mice. The other components can be added or removed as needed according to the experimental conditions.

[0024] Working principle: When personnel need to assemble the support frame 2 and the platform 1, they can use wire to tie the load-bearing net 11 and the contact net 12 together. The wire is fixed in a star-shaped distribution at the bottom of the load-bearing net 11. Then, when assembling the platform 1, the personnel can place the slot block 5 on the outer surface of the support frame 2 and use the limit bolt 4 to insert it into the limit hole to fix the platform 1. Then, the personnel can place the rat cage 3 on the top of the contact net 12 and place it at equal intervals. Next, the personnel can use the casters 7 to move the support frame 2, which facilitates the movement of the support frame 2 and can use the internal brake pads to fix the support frame 2.

[0025] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described again here.
