Description

Technical Field

[0001] This application relates to the field of experimental equipment technology, and more specifically, to an experimental animal impact testing device. Background Technology

[0002] Among existing technologies, using impact devices to construct corresponding animal trauma models is a common technique, but it still has certain limitations. For example, the method of constructing animal closed fracture models often involves using a weight of a selected weight to make the impact hammer fall freely from a specific height on a fixed rod, thereby impacting specific bone parts of the small animal.

[0003] However, the aforementioned modeling methods primarily rely on manual operation of the striking device or electromagnetic control by the experimenter, and the entire process depends heavily on experience. This method easily leads to inconsistent standards in the constructed fracture models, such as the inability to precisely control fracture parameters, which greatly affects the uniformity of experimental results and the reproducibility of the experimental process. In addition, this method is not convenient for striking different parts of the animal. If precise striking of different parts of the same animal is required in the experiment, it often requires repeated adjustments to the device or the animal's fixed position, affecting experimental efficiency and striking accuracy.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Embodiments of this application provide a laboratory animal impact testing device, such as... Figures 1 to 3 As shown, the experimental animal impact test apparatus includes a frame 100, a fixed platform, and an impact hammer.

[0031] like Figure 1 As shown, the frame 100 is fixedly installed. For example, the frame 100 is fixedly installed on the ground or other tabletop, such as a laboratory table, by means of welding, snap-fitting, riveting or bolting.

[0032] A fixing platform is mounted on the frame 100. The fixing platform is used to fix the test subject and keep the test subject in a fixed posture. Exemplarily, the test subject includes, but is not limited to, laboratory mice, rats, rabbits, or guinea pigs. The technical solution of this application will be described below using a mouse as an example.

[0033] An impact hammer is mounted on the frame 100. The impact hammer is used to strike mice and includes a movable arm and an impact tip.

[0034] A movable arm is mounted on the frame 100 and is capable of moving along a preset direction. For example, the preset direction includes the X-axis direction, the Y-axis direction, and / or the Z-axis direction, etc., and the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0035] The impact tip is used to strike the mouse. The impact tip is set on the moving arm. The movement of the moving arm causes the impact tip to move so that the impact tip can strike different parts of the mouse.

[0036] During use, the mouse's limbs are spread out and fixed to a platform. A movable arm moves the impact tip to the first test site on the mouse, where it strikes the first test site. The movable arm then moves the impact tip to the second test site, where it strikes the second test site. This process is repeated for other test sites on the mouse.

[0037] Because the moving arm can move along preset directions (such as the X, Y, and Z axes), the impact tip can be accurately positioned at any test site on the subject (such as a mouse). This design allows the testing device to be adapted to a variety of different testing needs, enabling impact tests on various parts of the body without the need to change or adjust the device.

[0038] With precise control of the moving arm, the impact tip can strike the designated area of ​​the test subject with great accuracy. This precision is crucial for scientific research, ensuring the reliability and accuracy of experimental results.

[0039] Because the moving arm of the impact hammer can move in multiple directions, the angle and force of the impact can be flexibly adjusted to meet different experimental requirements. This flexibility allows the experimental device to be applied more widely in various scientific research fields.

[0040] Automated control of the mobile arm simplifies the experimental process, reduces manual intervention, and thus improves the efficiency and accuracy of experiments. Furthermore, this automated control can reduce potential errors and deviations during the experiment.

[0041] In this application, a movable arm is used to move the impact tip, enabling the impact tip to strike different test sites on the mouse, thus improving adaptability and accuracy.

[0042] like Figure 1 As shown, in one embodiment, the experimental animal impact test apparatus further includes an anesthesia mask 200, which is connected to an anesthetic drug source and is used to anesthetize mice.

[0043] For example, the anesthetic agent source can provide anesthetic drugs to the anesthetic mask 200.

[0044] Mice can be rapidly and effectively anesthetized using an anesthesia mask 200, which can quickly bring them into a stable state, thereby shortening the experimental preparation time and improving the overall experimental efficiency.

[0045] Anesthetized mice can remain relatively still during experiments, reducing errors introduced by activity or struggle, thereby improving the accuracy and reliability of experimental data.

[0046] The use of the anesthesia mask 200 can ensure that mice do not feel pain or discomfort during the experiment, prevent mice from struggling and shaking, and improve the accuracy of the strike.

[0047] Anesthetized mice are easier to restrain and manipulate, allowing researchers to focus more on the experimental process itself, thus improving concentration and operational accuracy.

[0048] like Figure 1 As shown, in one embodiment, the experimental animal impact testing device further includes a first telescopic member 310, which is telescopic. One end of the first telescopic member 310 is fixedly mounted on the frame 100. Exemplarily, the first telescopic member 310 is fixedly connected to the frame 100 by welding, threaded engagement, snap-fitting, adhesive bonding, or other methods.

[0049] The other end of the first telescopic member 310 is connected to the anesthesia mask 200. The first telescopic member 310 can extend and retract to move the anesthesia mask 200 so that the anesthesia mask 200 moves away from or closer to the mouse's head.

[0050] For example, the first telescopic member 310 includes, but is not limited to: hydraulic telescopic rod, pneumatic telescopic rod, electric actuator, threaded screw mechanism, etc.

[0051] The first telescopic component 310 can extend and retract, thereby moving the anesthesia mask 200 so that it can precisely approach or move away from the mouse's head. This flexibility allows the experimenter to adjust the position of the anesthesia mask 200 as needed, ensuring the anesthesia effect while also improving the convenience of the experimental operation.

[0052] By precisely controlling the extension and retraction length of the first telescopic component 310, the position of the anesthesia mask 200 can be precisely controlled. This precise control helps ensure that the anesthetic drug acts accurately on the mouse's head, thereby improving the accuracy and reliability of the experiment.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, the fixing platform includes a fixing plate 400 and a torso fixing clamp 410.

[0054] A fixing plate 400 is fixedly mounted on the frame 100. The fixing plate 400 has a main plate body 402 for supporting the mouse's abdomen and four secondary plate bodies 404 for supporting the mouse's limbs. The four secondary plate bodies 404 are respectively fixedly connected to the main plate body 402 and correspond to the mouse's limbs. By using the main plate body 402 and the secondary plate bodies 404, the mouse's limbs can be spread out, making it easier to expose the test site and thus improving the accuracy of the strike.

[0055] The design of the fixing plate 400, particularly the combination of the main plate body 402 and the four auxiliary plate bodies 404, stably supports the mouse's abdomen and limbs, allowing the mouse to maintain a stable posture during the experiment. This stability helps the experimenter to more accurately locate the test site, thereby improving the precision of the impact test. By spreading and fixing the mouse's limbs to the auxiliary plate bodies 404, the test site can be easily exposed. This design helps the experimenter to observe the test process more intuitively and record the test results accurately.

[0056] The motherboard body 402 has a hollowed-out plate structure, which can prevent mouse urine, blood and other substances from accumulating on the motherboard body 402, thereby keeping the motherboard body 402 clean and hygienic. This not only helps to reduce contamination during the experiment, but also improves the accuracy of the experimental results.

[0057] like Figure 2 As shown, trunk fixation clips 410 are disposed on both sides of the fixation plate 400. The trunk fixation clips 410 are used to hold the mouse's trunk. The trunk fixation clips 410 have limb through-holes for the mouse's limbs to pass through, allowing the trunk fixation clips 410 to hold the mouse firmly without hindering the mouse's limbs from extending. The trunk fixation clips 410 further enhance the fixation effect of the fixation platform on the mouse. By holding the mouse's trunk, the trunk fixation clips 410 ensure that the mouse will not move or struggle during the experiment, thereby improving the stability and safety of the experiment. The limb through-holes on the trunk fixation clips 410 allow the mouse's limbs to pass through; this flexibility helps maintain the mouse's natural posture and reduces discomfort and stress during the experiment.

[0058] like Figure 1 As shown, in one embodiment, the fixing platform further includes a striking pad 420, and at least one striking pad 420 is slidably mounted on each sub-plate body 404.

[0059] like Figure 2As shown, by way of example, each subplate body 404 is slidably mounted with a striking pad 420. In use, the striking pad 420 is moved to a position opposite to the impact tip, so that the mouse's limb is located between the striking pad 420 and the impact tip. When the impact tip strikes the mouse's limb, the striking pad 420 can prevent the mouse's limb from rebounding or excessively indenting, which would cause the striking point to deviate. Setting the striking pad 420 can improve the striking accuracy.

[0060] In another embodiment, two impact pads 420 are slidably mounted on each subplate body 404.

[0061] The impact pad 420 uses a sliding installation method, allowing its position to be adjusted according to actual needs. This design not only facilitates operation but also improves the flexibility of the mechanical structure.

[0062] like Figure 1 and Figure 2 As shown, in one embodiment, the fixing platform further includes a neck fixing clip 430, which is disposed on the main body 402 and located at a corresponding position on the mouse's neck.

[0063] For example, the neck clamp 430 includes a mounting base, a first clamping plate, and a second clamping plate. The mounting base is fixedly mounted on the frame 100 or the main body 402. The first clamping plate and the second clamping plate are rotatably mounted on the mounting base. The first clamping plate and the second clamping plate can approach each other to clamp the neck of the mouse. A semi-circular groove is provided on the side of the first clamping plate near the second clamping plate, and a semi-circular groove is provided on the side of the second clamping plate near the first clamping plate. The semi-circular grooves on the first clamping plate and the second clamping plate can be combined to form a circular through hole. The inner wall of the circular through hole can clamp the neck of the mouse.

[0064] The neck clamp 430 securely holds the mouse's neck, ensuring the mouse maintains a stable posture during the experiment, preventing it from shaking or struggling. This helps improve the accuracy and reliability of the experiment and reduces errors caused by mouse movement.

[0065] By immobilizing the mice by the neck, the risk of accidental injury caused by the mice struggling or moving during the experiment can be reduced. This not only protects the safety of the experimenters but also ensures the smooth progress of the experiment.

[0066] like Figure 1 As shown, in one embodiment, the movable arm includes a second telescopic member 320, which is arranged along the X-axis direction and is capable of telescopic extension and retraction along the X-axis direction. An impact tip is disposed on the second telescopic member 320, and the extension and retraction of the second telescopic member 320 causes the impact tip to move along the X-axis direction.

[0067] For example, the second telescopic member 320 includes, but is not limited to: hydraulic telescopic rod, pneumatic telescopic rod, electric actuator, threaded screw mechanism, etc.

[0068] like Figure 1 As shown, in one embodiment, the movable arm further includes a third telescopic member 330, which is arranged along the Z-axis direction and is capable of telescopic extension and retraction along the Z-axis direction. A second telescopic member 320 is disposed on the third telescopic member 330. The extension and retraction of the third telescopic member 330 causes the second telescopic member 320 to move along the Z-axis direction, and the movement of the second telescopic member 320 along the Z-axis direction causes the striking tip to move along the Z-axis direction.

[0069] For example, the third telescopic component 330 includes, but is not limited to: hydraulic telescopic rod, pneumatic telescopic rod, electric actuator, threaded screw mechanism, etc.

[0070] like Figure 1 As shown, in one embodiment, the movable arm further includes a fourth telescopic member 340. The fourth telescopic member 340 is disposed on the frame 100 along the Y-axis direction, and the fourth telescopic member 340 is telescopic. A third telescopic member 330 is disposed on the fourth telescopic member 340, and the telescopic movement of the fourth telescopic member 340 causes the third telescopic member 330 to move along the Y-axis direction.

[0071] For example, the fourth telescopic member 340 includes, but is not limited to, a hydraulic telescopic rod, a pneumatic telescopic rod, an electric actuator, a threaded screw mechanism, etc. However, in another embodiment, the fourth telescopic member 340 is a gear and rack drive mechanism.

[0072] With the second telescopic member 320, the third telescopic member 330, and the fourth telescopic member 340, the impact tip can move in the X, Y, and Z axes, respectively. This three-dimensional movement capability allows the impact tip to reach a wider area and can be precisely adjusted for specific positions, thereby improving operational flexibility and accuracy.

[0073] In one embodiment, the third telescopic member 330 is rotatably mounted on the fourth telescopic member 340 about the Z-axis. In another embodiment, the second telescopic member 320 is rotatably mounted on the third telescopic member 330 about the Z-axis.

[0074] like Figure 1 and Figure 3 As shown, in one embodiment, the impact tip includes an air source 500, a pneumatic rod 510, and an impact block 520.

[0075] The pneumatic rod 510 is connected to the air source 500 to extend and retract; the impact block 520 is set on the pneumatic rod 510. When the pneumatic rod 510 extends, it causes the impact block 520 to approach and strike the mouse. The air source 500 can provide the pneumatic rod 510 with compressed gas of adjustable pressure to adjust the magnitude of the impact force of the impact block 520.

[0076] For example, the gas source 500 includes, but is not limited to, an air compressor, an air tank, etc.

[0077] For example, such as Figure 3 As shown, the pneumatic rod 510 has an air inlet 512 and an air outlet 514. The air inlet 512 is connected to the air source 500, which supplies compressed gas to the pneumatic rod 510 through the air inlet 512. The air outlet 514 is used to discharge the gas inside the pneumatic rod 510, and the air source 500 recovers the compressed gas through the air outlet 514.

[0078] By supplying the pneumatic rod 510 with compressed gas of adjustable pressure through the air source 500, the magnitude of the impact force of the impact block 520 can be precisely controlled to meet the requirements of accuracy and versatility in testing.

[0079] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
