Description

Technical Field

[0001] The present invention relates to the technical field of medical experimental instruments, and more particularly to a micro-controlled animal experimental striking device. Background Art

[0002] When the human body is hit by external force, such as stones, basketballs, door handles, car accidents, and other objects out of sight, in addition to obvious external injuries, the conduction of mechanical force will also affect the heart, brain, internal organs, bones and other organs, thereby indirectly causing damage. Most of these injuries are "internal injuries" that are difficult to observe with the naked eye.

[0003] In order to study the mechanism of "internal injuries" caused by external force, scientific researchers usually use experimental animals such as mice as experimental subjects to conduct beating experiments to simulate the state of the human body after being hit by external force. By hitting different parts of the experimental animals and the impact force, they study the relationship between it and various abnormal behaviors and abnormal indicators of the animals after being hit, and then they can formulate corresponding treatment plans according to different parts of the body hit and the degree of injury.

[0004] In existing technologies, when striking experimental animals, they typically need to be immobilized. During this process, the animals' heart rate, blood pressure, and other parameters fluctuate significantly, and secretions become unstable. Furthermore, existing striking devices are not intelligent and cannot precisely adjust the striking force and direction, resulting in low efficiency. Consequently, existing striking devices or methods are inefficient, and the resulting experimental data is unreliable. Summary of the Invention

[0005] In order to solve the technical problems raised in the above background technology, the present invention proposes a micro-controlled animal experimental striking device, and the specific technical solution is as follows:

[0006] A micro-controlled animal experimental striking device comprises at least a cylinder, a connecting seat, a core rod, a striking head and an angle adjustment unit. The cylinder is connected to the connecting seat, and the connecting seat is detachably connected to the angle adjustment unit. A core rod is arranged in the cylinder, and the core rod is connected to the striking head. The striking head extends out of the cylinder and is used to perform striking experiments on experimental animals, thereby studying the pathological characteristics after injury.

[0007] The angle adjustment unit includes an annular support and two semicircular sheet-shaped adjustment bodies. The support is provided with multiple hinge holes. Hinge columns are provided on the inner sides of both ends of each adjustment body. The hinge columns are adapted to the hinge holes. The two adjustment bodies are hinged on both sides of the support in an orthogonal posture.

[0008] Each of the adjusting bodies is provided with a strip hole. At the intersection position of the adjusting bodies, two of the strip holes intersect and define a working area channel SH. The connecting seat is fixed to the adjusting body through the mounting hole, so that a part of the cylinder and the striking head can extend into the working area channel SH.

[0009] The experimental animal is placed in the cavity formed in the middle of the support. In order to prevent the experimental animal from escaping, the regulating body is used as a bracket, surrounding the two regulating bodies and a sealing body is laid on the outer wall of the regulating body. The opening at the edge of the sealing body is pressed downward into the bottom of the support.

[0010] By manually adjusting the two adjusting bodies, the working area channel SH is quickly aligned with the location of the striking part, and the striking head is used to strike. Therefore, no matter how the experimental animal moves or changes its posture within the sealed body, the striking head can quickly and accurately align the working area channel SH with the location of the experimental animal's part to be struck.

[0011] The upper part of the core rod is provided with a limiting protrusion, the limiting protrusion is made of magnetic material, a slot is set in the limiting protrusion, and the handle is inserted into the slot to connect the core rod; an iron core is set in the cylinder and on the upper part of the limiting protrusion, a coil is wound around the iron core, and the coils are insulated by insulating glue; a spring is sandwiched between the iron core and the limiting protrusion, and the two ends of the spring are respectively fixed to the outer wall of the iron core and the outer wall of the limiting protrusion.

[0012] The outer wall of the cylinder is provided with a vertical slit, and during the striking / retracting action, the slit enables the handle to move within the space limited by the slit, preventing the handle from rotating.

[0013] The top of the iron core is connected to the nut through a thread, and a wiring terminal is provided on the nut. One side of the wiring terminal is connected to the two lead wires of the coil, and the other side of the wiring terminal is connected to the electronic control unit through a line. The electronic control unit adjusts the input current in the control coil.

[0014] By controlling the magnitude of the current through the electronic control unit, the magnitude of the magnetic repulsive force between the limiting protrusion and the iron core can be controlled, thereby controlling the striking force of the animal experiment striking device.

[0015] In summary, the advantages of the small animal blunt trauma striking system of the present invention compared with the prior art are:

[0016] 1) The present invention provides a micro-controlled animal experimental striking device. When performing striking experiments on animals, there is no need to fix the experimental animals. Moreover, no matter how the experimental animals move or change their postures within the sealed body, the striking head can quickly and accurately align the working area channel SH with the location of the part of the experimental animal to be struck.

[0017] 2) By controlling the current through the electronic control unit, the magnitude of the magnetic repulsive force between the limiting protrusion and the iron core can be controlled, thereby precisely controlling the striking force of the animal experiment striking device;

[0018] 3) The striking force of this experimental striking device can be adjusted, and the core rod can be quickly retracted after striking to avoid secondary impact and ensure the accuracy of experimental data; the striking head end can be replaced to simulate different experimental conditions.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please inspect Figure 1-2A micro-controlled animal experimental striking device includes at least a cylinder 1, a connecting seat 2, a core rod 3, a striking head 4 and an angle adjustment unit. The cylinder 1 is connected to the connecting seat 2, and the connecting seat 2 is detachably connected to the angle adjustment unit. The core rod 3 is arranged in the cylinder 1, and the core rod 3 is connected to the striking head 4. The striking head 4 extends out of the cylinder 1 and is used to perform striking experiments on experimental animals, and then study the pathological characteristics after injury.

[0027] The impact site can be the spinal cord, brain, bones, etc., and the animals can be experimental mice, rabbits, primates (such as monkeys), etc.

[0028] The angle adjustment unit includes an annular support 2-1 and two semicircular sheet-shaped adjustment bodies 2-5. The annular support 2-1 is provided with multiple hinge holes 2-2. A hinge column 2-4 is provided on the inner side of each end of each adjustment body 2-5. The hinge column 2-4 is adapted to the hinge hole 2-2. The two adjustment bodies 2-5 are hinged on both sides of the support 2-1 in an orthogonal posture (that is, the intersection angle of the vertical projections of the two adjustment bodies is 90°).

[0029] Each regulating body 2-5 is provided with a strip hole 2-6. At the intersection of the regulating bodies 2-5, the two strip holes 2-6 also intersect and define a working area channel SH. A mounting hole 13 is provided on the connecting seat 2. The connecting seat 2 is fixed to the regulating body 2-5 by means of a screw or a pin, so that a portion of the barrel 1 and the striking head 4 can extend into the working area channel SH.

[0030] The annular support 2-1 is made of a material with a relatively large mass, such as stainless steel, cast iron, ceramics, etc.

[0031] The experimental animals are placed in the cavity 2-3 in the middle of the annular support 2-1. In order to prevent the experimental animals from escaping, the regulating body 2-5 can be used as a bracket to surround the two regulating bodies and a sealing body is laid on the outer wall of the regulating body. The sealing body is made of coarse-pore fiber mesh or transparent film, and the opening at the edge of the sealing body is pressed downward into the bottom of the support 2-1, thereby preventing the experimental animals from escaping.

[0032] Because the two adjusting bodies 2-5 are orthogonal and have rotational freedom relative to the support 2-1, the two adjusting bodies 2-5 can be manually adjusted according to the location of the striking part of the experimental animal, so that the working area channel SH is quickly aligned with the location of the striking part, and the striking is performed using the striking head 4. Therefore, no matter how the experimental animal moves or changes its posture within the sealed body, the striking head 4 can quickly and accurately align the working area channel SH with the location of the experimental animal's part to be struck.

[0033] The upper part of the core rod 3 is provided with a limiting protrusion 26, which is made of magnetic material. A slot 24 is set in the limiting protrusion 26, and the handle 5 is inserted into the slot 24 to connect the core rod 3. An iron core 18 is set in the cylinder 1 and on the upper part of the limiting protrusion 26. The coil 10 is wound around the iron core 18, and the coils 10 are insulated by insulating glue 17; a spring 8 is sandwiched between the iron core 18 and the limiting protrusion 26, and the two ends of the spring 8 are respectively fixed to the outer wall of the iron core 18 and the outer wall of the limiting protrusion 26 (one end of the spring 8 can also be hung on the limiting protrusion 26).

[0034] A vertical slit 12 is provided on the outer wall of the barrel 1. During striking / retracting, the slit 12 enables the handle 5 to move within the space confined thereto, preventing the handle from rotating.

[0035] The top of the iron core 18 is connected to the nut 7 via threads. Nut 7 is provided with a terminal 19. One side of the terminal 19 is connected to the two lead wires of the coil 10. The other side of the terminal 19 is connected via a circuit to an electronic control unit (not shown in the figure 3). The electronic control unit can at least adjust the input current of the control coil 10. When the electronic control unit is connected to the coil 10, an electromagnetic field is generated at the end of the iron core 18, which in turn forms a magnetic repulsive force between the iron core 18 and the limiting protrusion 26. The core rod 3 moves downward, the spring 8 extends, and the striking head 4 strikes the target area of ​​the experimental animal. When the control coil 10 of the electronic control unit loses power, the core rod 3 moves upward due to the tension of the spring 8. At this time, the distance between the limiting protrusion 26 and the iron core 18 gradually approaches, generating a magnetic attraction. At the same time, in the process of the core rod 3 moving upward, when the spring height is less than the original length of the spring, the tension will be converted into elastic force. At this time, the magnetic attraction can offset this part of the elastic force, so that the handle position is stable during the retraction action. The length of the spring after compression is greater than the sum of the height of the limiting protrusion and the outer wall of the iron core, avoiding the collision between the iron core and the limiting protrusion 26. By quickly retracting the core rod 3, the problem of inaccurate experimental data caused by the experimental animal's emergency reaction instinctively colliding with the core rod 3 can be avoided.

[0036] By controlling the magnitude of the current through the electronic control unit, the magnitude of the magnetic repulsive force between the limiting protrusion 26 and the iron core 18 can be controlled, thereby precisely controlling the striking force of the animal experiment striking device.

[0037] Example 2

[0038] In this embodiment, a threaded hole is provided on the outside of the cylinder 1 , and the pressing handle 6 is hinged to the outside of the cylinder 1 through the threaded hole, the U-shaped piece 15 and the fixing screw 16 .

[0039] A barb 14 is provided on the upper portion of the handle 5, and a horizontal inward protrusion is formed on the side of the pressure handle 6 facing the handle 5, which interlocks with the barb 14. A spring 8 is sandwiched between the iron core 18 and the limiting protrusion 26, with its ends respectively abutting the outer wall of the iron core 18 and the outer side of the limiting protrusion 26. When engaged, the spring 8 is in a compressed state.

[0040] The upper portion of the core rod 3 is provided with a limiting protrusion 26 , which is made of magnetic material.

[0041] When performing a striking action, the handle 5 is pressed, the inner convex part is disengaged from the barb 14, and under the elastic force of the spring 8, the core rod 3 moves downward, the spring 8 extends, and drives the striking head 4 to strike the part to be struck of the experimental animal; when performing a retraction action, the current in the coil 10 is controlled by the electronic control unit to flow in the opposite direction, thereby generating a magnetic attraction force between the iron core 18 and the limiting protrusion 26, and the core rod 3 moves upward. At this time, the distance between the limiting protrusion 26 and the iron core 18 gradually approaches. When the electronic control unit detects that the inner convex part is engaged with the barb 14 again, the electronic control unit controls the coil 10 to lose power.

[0042] In addition, in some cases, the experimental site is relatively dim or a shadow appears in the micro-controlled animal experimental striking device. In order to ensure the normal progress of the striking experiment, the lamp 9 can be installed through the installation hole 13, and the lamp 9 illuminates the striking part; in order to more accurately aim at the striking part, the lamp 9 can use a laser lamp.

[0043] The outer side of the lower portion of the cylinder 1 has an external thread 11 , and the inner side of the connecting seat 2 has an internal thread 22 . The cylinder 1 can be fixedly connected to the connecting seat 2 through the external thread 11 and the internal thread 22 .

[0044] The bottom of the core rod 3 has a clamping end 21, and a clamping blind hole 20 is formed in the clamping end 21. The clamping blind hole 20 is connected to the striking head end 25. The striking head end 25 can be soft or hard, and the striking head end 25 can be replaced through the clamping blind hole 20 to simulate different experimental conditions.

[0045] In summary, the present invention provides a micro-controlled animal experimental striking device that eliminates the need to secure the experimental animal during striking experiments. Furthermore, regardless of how the experimental animal moves or changes its posture within the sealed body, the striking head can quickly and accurately align the working area channel SH with the location of the experimental animal's struck area. Furthermore, the striking force of the experimental striking device can be adjusted, and the core rod 3 can be quickly retracted after striking to avoid secondary impacts and ensure accurate experimental data. Furthermore, the end of the striking head can be replaced to simulate different experimental conditions.

[0046] It should be noted that the specific embodiments of the present invention only describe in detail some representative embodiments in the specification of the present invention. For those skilled in the art, various obvious changes thereto are within the scope of protection of the present invention without violating the original spirit and protection scope of the present invention.
