Abstract
Description
Technical Field
[0001] This invention relates to the field of animal restraint technology, specifically to a flexible long-term restraint device for rats and mice. Background Technology
[0002] In biomedical research experiments, restraining laboratory animals (such as mice and rats) is a common procedure. This safely restricts animal movement, reduces stress and injury, and allows the animal to be held in a specific position as needed for procedures such as injection, blood collection, measurement, and surgery. Existing restraint devices are mainly divided into restraint devices / frames and restraint bags.
[0003] Restraints / frames are typically made of rigid materials, restricting animal movement through physical structure and spatial constraints. While they provide a relatively secure hold around the animal's mouth and tail, some movement is still possible around the body, especially in the limbs, which are difficult to immobilize and usually require straps / ropes. Prolonged immobilization can easily lead to limb ischemia. Furthermore, rigid restraints can easily trigger stress responses in animals, and prolonged immobilization can cause pressure and discomfort. Therefore, restraints / frames are mostly used for short-term procedures such as sampling and injection while the animal is awake, or for longer procedures under anesthesia. However, for situations requiring long-term, conscious restraint, especially when maintaining a fixed position or performing manipulations on the limbs, the stability of restraints / frames is poor.
[0004] Restraint bags are made of soft material, allowing animals some degree of movement during use. Manual assistance is needed to restrain body parts, and animals are prone to escape during prolonged use. Therefore, restraint bags are primarily used for short-term procedures or animal transport. Restraint bags cannot meet the need for prolonged restraint and immobilization of animals while they are awake. Utility Model Content
[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a flexible, long-duration restraint device for rats and mice, solving the problem that existing restraint devices cannot perform safe and comfortable restraint operations for extended periods while the animal is awake.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A flexible long-term restraint device for rats and mice is provided, comprising a base, a fixing net, restraint fasteners, and a fixing strap;
[0008] The base includes a base plate, and a support assembly is provided below the base plate;
[0009] The fixing mesh is set above the base, and the fixing mesh has evenly distributed mesh holes. The fixing mesh is connected to the base by a fixing component.
[0010] Baoding fasteners are used to secure the base and the mesh, restricting the movement and position of laboratory mice.
[0011] The fixing straps are fitted on both sides of the base plate. One end of the fixing strap is provided with a fixing buckle, and the inside of the fixing buckle is provided with a through hole. The front side of the other end of the fixing strap is provided with a third hook and loop fastener layer, and the rear side of the other end of the fixing strap is provided with a third hook and loop fastener layer that matches the third hook and loop fastener layer.
[0012] The beneficial effects of adopting the above technical solution are as follows: the support component improves the stability of the base, and its height facilitates operation; the fixing component ensures the fixing net is firmly attached to the base, preventing escape; the base plate is used to place laboratory mice (such as rats and mice), which are restrained under the fixing net. The net secures the mice to the base plate, and the fasteners individually reinforce and maintain the position of each part of the mouse's body. This not only allows the fixing net to fit tightly against the mouse's body, restricting its movement of body and limbs, but also allows for different positions according to experimental needs and can be used for mice of various weights. Furthermore, when restraining the mouse in the fixing net, the fasteners fix the net to the base, restricting the mouse's movement and effectively ensuring long-term stability and reliability during restraint. Simultaneously, the evenly distributed mesh on the fixing net facilitates the insertion of syringes and other instruments, making experimental operations convenient. The fixing straps on both sides of the base plate can be fitted onto the base plate as needed. By passing the fixing straps around the fixing net from under the base plate, passing one end of the fixing strap through the fixing buckle, and adjusting the tightness of the fixing straps as needed, the third hook and loop fastener surface layer and the third hook and loop fastener hook surface layer can be glued and fixed, thus completing the secondary fixation of the fixing net. The fixing straps can effectively prevent the experimental mice from escaping, improving the stability and reliability of the fixation.
[0013] This flexible, long-duration restraint device for rats and mice achieves prolonged immobility while the mice are awake through the coordinated use of a fixing net, base, restraint fasteners, and fixing straps. It can fix various parts of the mouse's body (head, neck, trunk, and limbs), while improving the mouse's comfort and reducing stress response. This facilitates long-duration restraint operations, and the device can be fixed in different positions according to experimental needs. It is suitable for rats and mice of various weights and has better economic benefits and practicality.
[0014] Furthermore, the support assembly includes a left fixed base and a right fixed base, which are located below the base plate.
[0015] The beneficial effects of adopting the above technical solution are as follows: the left and right fixed bases are used to improve the stability of the base, and the left and right fixed bases have a certain height, which is conducive to the operation of the operator.
[0016] Furthermore, the fixing component includes a fixing piece, a first hook and loop fastener surface layer, and a first hook and loop rough surface layer that matches the first hook and loop fastener surface layer; the fixing piece is disposed on one side of the fixing mesh, and the fixing piece is connected to the near lower side of the base plate by rivets; the first hook and loop rough surface layer is disposed on the upper side of the far end of the base plate, the outer side of the left fixing base and the right fixing base; the first hook and loop fastener surface layer is disposed on the other three sides of the fixing mesh.
[0017] The beneficial effects of adopting the above technical solution are as follows: the fixing plate is fixed to the other side of the base plate with rivets before the experimental mouse is placed in, which improves the convenience of operation. The fixing net can be firmly attached to the left fixing base, the right fixing base and the base plate by the bonding and fixing of the first hook and loop fastener surface layer and the first hook and loop fastener hook surface layer, so as to prevent the experimental mouse from escaping.
[0018] Furthermore, the support assembly includes several support legs, which are located below the base plate; the fixing mesh is cross-shaped and includes a first fixing strip and a second fixing strip.
[0019] Furthermore, the fixing component includes a second hook-and-loop fastener surface layer and a second hook-and-loop fastener hook surface layer, which are symmetrically disposed at both ends of the first fixing strip and the second fixing strip, respectively.
[0020] The beneficial effects of adopting the above technical solution are as follows: setting several support legs under the base plate can improve the stability of the entire restraint device, and can form a fixed space for the fixing net under the base plate, which makes it easy for the cross-shaped fixing net to be glued and fixed through the symmetrically arranged second hook and loop fastener surface layer and second hook and loop fastener hook surface layer. This not only reduces the loosening or displacement of the fixing net due to uneven force, but also makes it easy for the experimenter to quickly adjust the tightness of the fixing net as needed to adapt to experimental mice of different sizes or positions.
[0021] Furthermore, the fixing component includes several fixing holes and several fixing ropes, with the fixing ropes fixedly disposed with respect to the fixing holes, and the fixing holes and fixing ropes respectively disposed at both ends of the first fixing strip and the second fixing strip.
[0022] The beneficial effects of adopting the above technical solution are as follows: after the fixing rope passes through the fixing hole and is tightened and tied with a rope buckle, the stability of the fixing net can be ensured and the loosening caused by the struggle or movement of the experimental mouse can be avoided. The tightness can be adjusted according to the animal's weight and fixing position. In addition, the use of multiple fixing holes and multiple fixing ropes can avoid discomfort or injury to the experimental mouse caused by excessive pressure in a single position, thereby ensuring the comfort of the experimental mouse during the fixing process and reducing stress response.
[0023] Furthermore, the base plate is made of rubber or cork; the fixing mesh is made of nylon or metal mesh.
[0024] The beneficial effects of adopting the above technical solution are as follows: the texture of materials such as rubber or cork is moderately soft and hard, which facilitates the penetration of fixation pins, reduces the difficulty and complexity of the operation process, improves the operation efficiency, and can fit tightly around the fixation pin after penetration, thereby improving the stability of fixation; while the fixation net made of flexible materials such as nylon or metal mesh has both flexibility and toughness, which can not only improve the fixation connection and comfort between the fixation net and the experimental mouse, but also adapt to experimental mice of different weights and sizes and different fixation positions, thereby ensuring fixation stability and flexibility.
[0025] Furthermore, several Baoding fasteners include fixing nails, which include nail heads and nail bodies. The diameter of the nail head is larger than the diameter of the mesh opening of the fixing mesh. The nail body passes through the fixing mesh and is inserted into the base plate to the bottom of the base plate. The end of the nail body is fixed by a butterfly buckle.
[0026] The beneficial effects of adopting the above technical solution are as follows: When the diameter of the nail head is larger than the diameter of the mesh of the fixing net, the fixing nail can effectively prevent the fixing net from falling off the base plate. Then, the end of the nail body is fixed by the butterfly buckle, which improves the stability and restraint effect of the entire restraint device and prevents the experimental mouse from escaping. In addition, after the fixing net is tightened and fixed to the base, the fixing nail can further fix the fixing net tightly around the experimental mouse's body. It can not only be flexibly adjusted according to the shape and size of the experimental mouse, improving the restraint flexibility, but also fix the experimental mouse in different positions (such as prone and supine positions with limbs extended, lateral position, abdominal position, etc.) according to experimental needs, thereby meeting the needs of various experimental operations. At the same time, it avoids compressing the experimental mouse, improves the comfort of the experimental mouse, reduces stress response, and ensures that the experimental mouse can remain still for a long time in a conscious state, thus improving the restraint effect, practicality and flexibility of the restraint device.
[0027] Furthermore, the base plate, the left fixing base, and the right fixing base are made of magnetic metal material. The fixing components include magnetic strips, which are arranged around the fixing mesh. The fixing fasteners include magnetic buckles, and the diameter of the magnetic buckles is larger than the mesh diameter of the fixing mesh.
[0028] The beneficial effects of adopting the above technical solution are as follows: the base plate is made of magnetic metal material, and magnetic strips are set around the fixing net. Through magnetic adsorption, the fixing net can be quickly and firmly fixed to the base plate. Then, the experimental mice of different sizes and positions can be fixed by magnetic buckles. This not only can adapt to experimental mice of different sizes and experimental needs, but also simplifies the operation process, ensures the stability and reliability of the fixation, and improves experimental efficiency.
[0029] Furthermore, the upper surface of the base plate is provided with an anti-slip layer, which is made of one or more of the following materials: silicone, rubber, cotton, and linen.
[0030] The beneficial effects of adopting the above technical solution are as follows: the anti-slip layer can increase the friction between the experimental mouse and the base plate, preventing the experimental mouse from shifting or deviating during the experiment; the soft and elastic materials such as silicone can relieve pressure, improve the comfort of the experimental mouse when it is placed and fixed, thereby reducing stress response and reducing body heat loss, ensuring that the experimental mouse can remain still for a long time in a conscious state.
[0031] In summary, the beneficial effects of the flexible long-term restraint device for rats and mice provided by this utility model are as follows:
[0032] This restraint device has a simple structure and uses a net made of flexible material to fix the experimental mice. It can keep the experimental mice in an immobile state for a long time while they are awake, and all parts of the body (head, neck, trunk, and limbs) can be fixed. It can be fixed in different positions according to experimental needs and is also suitable for mice and rats of various weights. At the same time, it improves the comfort of the experimental mice, reduces the stress response of the experimental mice, and has better operability and practicality. Attached Figure Description

[0048] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.
[0049] Example 1
[0050] like Figures 1-4 As shown, the flexible long-term restraint device for mice and rats provided by this utility model includes a base 1, a fixing net 7, and restraint fasteners; the base 1 includes a base plate 2, and a support assembly is provided below the base plate 2. The support assembly includes a left fixing base 3 and a right fixing base 4, which are located below the base plate 2. Fixing straps 6 are fitted on both sides of the base plate 2, as shown. Figure 13As shown, a fixing buckle 24 is provided at one end of the fixing strap 6, and a through hole 25 is provided on the inner side of the fixing buckle 24. A third hook and loop fastener surface layer 22 is provided on the front side of the other end of the fixing strap 6, and a third hook and loop fastener hook surface layer 23 matching the third hook and loop fastener surface layer 22 is provided on the rear side of the other end of the fixing strap 6. The fixing net 7 is provided above the base 1. The fixing net 7 is provided with evenly distributed mesh holes. The fixing net 7 is connected to the base 1 by a fixing component. The fixing component includes a first hook and loop fastener surface layer 8 and a first hook and loop fastener surface layer 5 matching the first hook and loop fastener surface layer 8. The first hook and loop fastener surface layer 5 is provided on one side of the base plate 2, the outer side of the left fixing base 3 and the right fixing base 4. A fixing piece 9 is provided on one side of the fixing net 7. The fixing piece 9 is fixed to the other side of the base plate 2 by several fasteners. The first hook and loop fastener surface layer 8 is provided on the other three sides of the fixing net 7.
[0051] The base plate 2 is used to place the experimental mouse, and the fixing net 7 is used to fix the experimental mouse on the base plate 2. The left fixing base 3 and the right fixing base 4 are used to improve the stability of the base 1. The left fixing base 3 and the right fixing base 4 have a certain height, which is convenient for operators to operate. At the same time, the fixing plate 9 is fixed to the other side of the base plate with fasteners before the experimental mouse is placed in, which ensures the stability of the fixing net 7 and improves the convenience of operation. After the fixing plate 9 is fixed, the experimental mouse is placed on the base plate 2, and its posture and position are adjusted so that its body is in the center of the base plate 2, and the limbs and body of the experimental mouse are within the mesh range of the fixing net 7. Then, the first hook and loop fastener layer 5 is attached and fixed to the first hook and loop fastener layer 8 on the other three sides of the fixing net 7, so that the fixing net 7 can be firmly attached. To prevent the experimental mice from escaping, fasteners are used on the base 1, left-side fixing base 3, and right-side fixing base 4 to individually secure different parts of the mouse's body. This not only allows the fixing net 7 to fit tightly against the mouse's body, restricting its body and limb movement, but also allows for fixing in different postures and positions according to experimental needs. It can also be used for mice and rats of various weights. At the same time, the evenly distributed mesh holes on the fixing net 7 facilitate the insertion of syringes and other instruments, making experimental operations convenient. In addition, the fixing strap 6 is wrapped around the fixing net 7 from under the base plate 2, with one end of the fixing strap 6 passing through the fixing buckle 24. The tightness of the fixing strap 6 is then adjusted as needed, and the third hook and loop fastener layer 22 and the third hook and loop fastener layer 23 are attached and fixed, thus completing the secondary fixation of the fixing net 7, further improving the stability and reliability of the fixation.
[0052] like Figure 1 and Figure 4As shown, several restraining fasteners include fixing nails 10, each comprising a nail head and a nail body. The diameter of the nail head is larger than the diameter of the mesh openings of the fixing mesh 7. The nail body passes through the fixing mesh 7 and is inserted into the base plate 2 to below the base plate 2. The end of the nail body is secured by a butterfly buckle 12. When the diameter of the nail head is larger than the diameter of the mesh openings of the fixing mesh 7, the fixing nail 10 effectively prevents the fixing mesh 7 from falling off the base plate 2. The butterfly buckle 12 further secures the end of the nail body, preventing the experimental mouse from escaping and improving the flexibility, stability, and restraining effect of the entire restraining device. Additionally, when the fixing mesh 7 is stretched and adhered to the base 1... The fixation pins 10 can further secure the fixation net 7 tightly around the body of the experimental mouse, setting it to different positions. This not only allows for flexible adjustment and secure restraint according to the shape and size of the experimental mouse, avoiding pressure on the mouse, improving the mouse's comfort, and reducing stress response, thus ensuring that the experimental mouse can remain still for a long time while conscious, but also allows the experimental mouse to be fixed in different positions (such as prone and supine positions with limbs extended, lateral position, abdominal position, etc.) according to experimental needs, thereby meeting the needs of various experimental operations and improving the practicality and flexibility of the restraint device.
[0053] In this embodiment, the base plate 2 is made of materials such as rubber or cork; the fixing net 7 is made of materials such as nylon or metal mesh. Rubber or cork has a moderate hardness, facilitating the penetration of the fixing nails 10, reducing the difficulty and complexity of the operation, improving operational efficiency, and allowing it to fit tightly around the fixing nails 10 after penetration, thereby improving the stability of the fixation. The fixing net 7, made of flexible materials such as nylon or metal mesh, combines flexibility and toughness, not only improving the fixation connection and comfort between the fixing net 7 and the experimental mouse, but also adapting to experimental mice of different weights and sizes, and different fixation positions, thus ensuring both flexibility and stability of the fixation.
[0054] Example 2
[0055] like Figures 5-7As shown, the mouse flexible long-term restraint device provided in this embodiment includes a base 1, a fixing net 7, restraint fasteners, and a fixing strap 6; the base 1 includes a base plate 2, the base plate 2 being made of rubber or cork, etc., and a support assembly is provided below the base plate 2, the support assembly including several support legs 13, the support legs 13 being located below the base plate 2; the fixing net 7 is located above the base 1, and the fixing net 7 has evenly distributed mesh holes; the fixing net 7 is made of nylon or metal mesh, etc., and the fixing net 7 is cross-shaped, including a first fixing strip 14 and... The second fixing strip 15 includes a second hook-and-loop fastener layer 16 and a second hook-and-loop fastener layer 17, which are symmetrically arranged at both ends of the first fixing strip 14 and the second fixing strip 15, respectively. The fixing mesh 7 is connected to the base 1 by a plurality of fasteners, including a fixing nail 10. The fixing nail 10 includes a nail head and a nail body. The diameter of the nail head is larger than the diameter of the mesh of the fixing mesh 7. The nail body passes through the fixing mesh 7 and is inserted into the base plate 2 to the bottom of the base plate 2. The end of the nail body is fixed by a butterfly buckle 12.
[0056] In this embodiment, the several support legs 13 located below the base plate 2 can improve the stability of the entire restraint device and form a fixing space for the fixing net 7 below the base plate 2. The experimental mouse is placed on the base plate 2, its posture is adjusted so that its body is in the center of the base plate 2, and the limbs and body of the experimental mouse are within the mesh area of the fixing net 7. Then, the two ends of the first fixing strip 14 of the fixing net 7 are pulled downwards from the base plate 2 respectively, so that the second hook-and-loop fastener surface layer 17 is aligned and fixed with the second hook-and-loop fastener rough surface layer 16 below the base plate 2. This ensures that the fixing net 7 is flat and firmly attached to the base 1. Finally, the two ends of the second fixing strip 15 of the fixing net 7 are separated... Do not pull downwards on the base 1. Align and fix the second hook-and-loop fastener 17 of the second fixing strip 15 with the second hook-and-loop fastener 16 below the base plate 2. This allows for the fixation of the experimental mouse via the fixing net 7. The tightness of the fixing net 7 can be adjusted according to the size of the experimental mouse and experimental requirements to ensure a close fit to the mouse's body. Finally, the fixing nail 10 passes through the mesh of the fixing net 7 and is inserted into the base plate 2 to the bottom of the base plate 2. Depending on the experimental requirements, the experimental mouse can be fixed in different positions (such as prone and supine positions with limbs extended, lateral positions, abdominal positions, etc.) to meet the needs of various experimental operations and improve the practicality and flexibility of the restraint device.
[0057] Example 3
[0058] like Figure 7 , Figure 8 and Figure 9As shown, the mouse flexible long-term restraint device provided in this embodiment includes a base 1, a fixing net 7, restraint fasteners, and a fixing strap 6; the base 1 includes a base plate 2, the base plate 2 being made of rubber or cork, etc., and a support assembly is provided below the base plate 2, the support assembly including several support legs 13, the support legs 13 being located below the base plate 2; the fixing net 7 is located above the base 1, and the fixing net 7 has evenly distributed mesh holes; the fixing net 7 is made of nylon or metal mesh, etc., and the fixing net 7 is cross-shaped, including a first fixing strip 14 and a second fixing strip 14. The fixing component 15 includes several fixing holes 18 and several fixing ropes 19. The fixing ropes 19 are fixedly installed with the fixing holes 18. The fixing holes 18 and fixing ropes 19 are respectively installed at the two ends of the first fixing strip 14 and the second fixing strip 15. The fixing net 7 is connected to the base 1 by several fasteners. The fasteners include fixing nails 10. The fixing nails 10 include nail heads and nail bodies. The diameter of the nail head is larger than the diameter of the mesh of the fixing net 7. The nail body passes through the fixing net 7 and is inserted into the base plate 2 to the bottom of the base plate 2. The end of the nail body is fixed by a butterfly buckle 12.
[0059] In this embodiment, the base plate 2 is made of materials such as rubber or cork. Several support legs 13 located below the base plate 2 improve the stability of the entire restraint device and create a fixing space for the fixing net 7 below the base plate 2. The fixing net 7 is positioned above the base plate 2. The experimental mouse is placed on the base plate 2 in the desired position, with its body centered on the base plate 2, ensuring that the mouse's limbs and body are within the mesh area of the fixing net 7. Then, the two ends of the first fixing strip 14 of the fixing net 7 are pulled downwards towards the base plate 2, causing several fixing ropes 19 on the first fixing strip 14 to pass through the fixing holes 18 and be tied tightly below the base plate 2, ensuring a secure fit. The fixing net 7 is firmly attached to the surface of the experimental mouse's body. Then, the two ends of the second fixing strip 15 of the fixing net 7 are pulled downwards towards the base 1, so that several fixing ropes 19 of the second fixing strip 15 are fastened to several fixing holes 18 on the second fixing strip 15 below the base plate 2, thereby fixing the experimental mouse through the fixing net 7. Then, the fixing nail 10 is inserted into the base plate 2 below the base plate 2 through the mesh holes of the fixing net 7. The diameter of the nail head is larger than the diameter of the mesh hole to prevent the fixing net 7 from falling off. Then, the end of the fixing nail 10 is fixed with a butterfly buckle 12 to further enhance the stability of the fixing net 7 and maintain the mouse in a specific position to prevent the experimental mouse from escaping.
[0060] Example 4
[0061] like Figures 10-14As shown, the mouse flexible long-term restraint device provided in this embodiment includes a base 1, a fixing net 7, restraint fasteners, and a fixing strap 6. The base plate 2 is made of magnetic metal material, and a support assembly is provided below the base plate 2. The support assembly includes a left fixing base 3 and a right fixing base 4, which are located below the base plate 2. The base plate 2, the left fixing base 3, and the right fixing base 4 are all made of magnetic metal material. The fixing net 7 is located above the base 1 and has evenly distributed mesh holes. The mesh hole diameter of the fixing net 7 is 20-30 meshes. The fixing net 7 is made of nylon or metal mesh, etc. The fixing assembly includes magnetic strips 21, which are arranged around the fixing net 7. The fixing net 7 is connected to the base 1 by several restraint fasteners, including magnetic buckles 20, the diameter of which is larger than the diameter of the mesh holes of the fixing net 7.
[0062] In this embodiment, the base 1 consists of a base plate 2, a left fixing base 3, and a right fixing base 4. The base plate 2, the left fixing base 3, and the right fixing base 4 are all made of magnetic metal materials to provide stable support and magnetic fixation. Different materials with different magnetic attraction forces can be selected according to the weight or size of the experimental mice to ensure the stability of the magnetic fixation. In use, the experimental mouse is placed on the base plate 2 and then fixed by the fixing net 7. The fixing net 7 is made of nylon or metal mesh and has evenly distributed mesh holes for fixing the experimental mouse. Magnetic strips 21 are set around the fixing net 7. The magnetic attraction between the magnetic strips 21 and the magnetic metal material of the base 1 can firmly attach the fixing net 7 to the base 1. Then, according to the experimental operation requirements, the experimental mouse is fixed in different postures by magnetic buckles 20. The diameter of the magnetic buckles 20 is larger than the diameter of the mesh holes of the fixing net 7, which can effectively prevent the fixing net 7 from falling off.
[0063] In this embodiment, an anti-slip layer 11 is provided on the upper surface of the base plate 2. The anti-slip layer 11 is made of materials such as silicone, which can increase the friction between the experimental mouse and the base plate 2, prevent the experimental mouse from shifting or deviating during the experiment, and ensure that the experimental mouse can remain still for a long time while in a conscious state. At the same time, the anti-slip layer 11 can also improve the comfort of the experimental mouse when it is placed and fixed, thereby reducing stress response.
[0064] In summary, this flexible long-term restraint device for rats and mice has a simple structure. It uses a fixing net 7 made of flexible material to fix the experimental mice, enabling them to remain immobile for a long time while awake. All parts of the body (head, neck, trunk, and limbs) can be fixed. The experimental mice can be fixed in different positions according to experimental needs and is suitable for rats and mice of various weights. At the same time, it improves the comfort of the experimental mice, reduces their stress response, and has better operational flexibility and practicality.
