Description

Technical Field

[0001] The present invention relates to the technical field of medical experimental instruments, and more specifically, 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 field of vision, 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, and most of these injuries are "internal injuries" that are not easily observed by the naked eye.

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

[0004] In the prior art, when hitting experimental animals, they usually need to be fixed, and during the fixation process, the animal's heart rate, blood pressure, etc. will change greatly, and the secretion will be unstable; in addition, the existing hitting device is not intelligent, and it is impossible to accurately adjust the hitting force and hitting direction, and the efficiency is low. Therefore, the existing hitting device or hitting method is inefficient, and the reliability of the experimental data obtained thereby is not high. 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 at least comprises a barrel, a connecting seat, a core rod, a striking head and an angle adjustment unit, wherein the barrel is connected to the connecting seat, the connecting seat is detachably connected to the angle adjustment unit, a core rod is arranged in the barrel, the core rod is connected to the striking head, the striking head extends out of the barrel, and is used to perform striking experiments on the experimental animals, and further study 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 a plurality of 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 an installation 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 bodies. 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 position of the striking part, and the striking head is used to strike. Therefore, no matter how the experimental animal moves in the sealed body or how its posture changes, the striking head can quickly and accurately align the working area channel SH with the position of the part to be struck of the experimental animal.

[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 arranged in the limiting protrusion, and the handle is inserted into the slot to connect the core rod; an iron core is arranged 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 to prevent 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 can at least adjust the input current in the control coil.

[0014] By controlling the magnitude of the current through the electric control unit, the magnitude of the magnetic repulsion 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 small animal blunt trauma striking system of the present invention has the following advantages compared with the prior art:

[0016] 1) The micro-controlled animal experimental striking device of the present invention does not need to fix the experimental animal when performing striking experiments on the animal, and no matter how the experimental animal moves in the sealed body or how its posture changes, the striking head can quickly and accurately align the working area channel SH with the position of the experimental animal's part to be struck;

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

[0018] 3) The striking force of the experimental striking device can be adjusted, and the core rod 13 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 be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] Please inspect Figure 1-2A micro-controlled animal experimental striking device at least includes 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 striking sites may be the spinal cord, brain, bones, etc., and the animals may 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 a plurality of hinge holes 2-2. Hinge columns 2-4 are provided on the inner sides of both ends of each adjustment body 2-5. The hinge columns 2-4 are adapted to the hinge holes 2-2. The two adjustment bodies 2-5 are hinged on both sides of the support 2-1 in an orthogonal posture (i.e., the intersection angle of the vertical projections of the two adjustment bodies is 90°).

[0029] Each adjusting body 2-5 is provided with a strip hole 2-6. At the intersection of the adjusting 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 adjusting body 2-5 by means of a screw or a pin, so that a part of the cylinder 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 cloth 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] Since 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 position of the hitting part of the experimental animal, so that the working area channel SH is quickly aligned with the position of the hitting part, and the hitting is performed using the hitting head 4. Therefore, no matter how the experimental animal moves in the sealed body or how its posture changes, the hitting head 4 can quickly and accurately align the working area channel SH with the position of the part to be hit of the experimental animal.

[0033] The upper part of the core rod 3 is provided with a limiting protrusion 26, and the limiting protrusion 26 is made of magnetic material. A slot 24 is arranged 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 arranged 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 cylinder 1. During the striking / retracting action, the slit 12 enables the handle 5 to move within the space it limits, thereby preventing the handle from rotating.

[0035] The top of the iron core 18 is connected to the nut 7 through a thread, and a terminal 19 is provided on the nut 7. One side of the terminal 19 is connected to the two lead wires of the coil 10, and the other side of the terminal 19 is connected to the electric control unit (not shown in the figure 3) through a line. The electric control unit can at least adjust the input current in the control coil 10. When the electric control unit is connected to the coil 10, an electromagnetic field is generated at the end of the iron core 18, and then a magnetic repulsion force is formed between the iron core 18 and the limiting protrusion 26, 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 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 limit 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 limit protrusion and the outer wall height of the iron core, avoiding the iron core from colliding with the limit protrusion 26. By quickly retracting the core rod 3, the problem of inaccurate experimental data caused by the experimental animal's emergency response instinctively colliding with the core rod 3 can be avoided.

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

[0037] Embodiment 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 member 15 and the fixing screw 16 .

[0039] A barb 14 is provided on the upper part of the handle 5, and a horizontal inner convex portion is formed on the side of the pressure handle 6 facing the handle 5, and the inner convex portion is engaged with the barb 14. 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 in contact with the outer wall of the iron core 18 and the outer side of the limiting protrusion 26, and the spring 8 is in a compressed state when engaged.

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

[0041] When performing a striking action, the handle 5 is pressed down, 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 retracting action, the electric control unit controls the current in the coil 10 to flow in the opposite direction, thereby generating a magnetic attraction force between the battery 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 electric control unit detects that the inner convex part is engaged with the barb 14 again, the electric 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 is directed toward the striking part for illumination; in order to aim at the striking part more urgently, the lamp 9 can use a laser lamp.

[0043] The outer side of the lower part 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 micro-controlled animal experimental striking device of the present invention does not need to fix the experimental animal when performing striking experiments on the animal, and no matter how the experimental animal moves in the sealed body or how the posture changes, the striking head can quickly and accurately align the working area channel SH with the position of the experimental animal to be struck. In addition, the striking force of the experimental striking device can be adjusted, and the core rod 13 can be quickly retracted after striking to avoid secondary impact and ensure the accuracy of the experimental data. In addition, 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 protection scope of the present invention without violating the original spirit and protection scope of the present invention.
