Description

Technical Field

[0001] The invention relates to the technical field of experimental auxiliary devices, and in particular to an automatic quantitative gastric administration device for animals used in traditional Chinese medicine pharmacology experiments. Background Art

[0002] In traditional Chinese medicine pharmacology experiments, automated quantitative gavage of animals is of great scientific significance and practical value. The automated quantitative gavage device can precisely control the drug dosage and administration time, ensuring the accuracy and repeatability of the experiment and avoiding deviations in experimental results caused by human error during manual operation.

[0003] Generally speaking, when using an automatic quantitative gavage device, animals will move around due to their own resistance. The animal's resistance behavior will affect the precise control of the dosage and time of administration, thereby affecting the accuracy of the experimental data.

[0004] In summary, how to solve the problem of inaccurate experimental data due to animal movement during drug administration has become a technical challenge that technicians in this field urgently need to solve. Therefore, it is necessary to propose an automatic quantitative gavage drug administration device for animals used in traditional Chinese medicine pharmacology experiments. Summary of the Invention

[0005] To address the aforementioned issues, the present invention provides an automatic quantitative oral dosing device for animals used in traditional Chinese medicine pharmacology experiments. The device utilizes a rack that moves downward, driving a fixed plate to move downward, thereby securing the animal's body and a clamping claw to secure the animal's head. The fixed plate and clamping claws secure the animal's body and head, respectively, preventing the animal from moving during oral dosing. This allows staff to precisely control the dosing dosage and timing, improving the accuracy of experimental data.

[0006] In order to achieve the above purpose, the technical solution of the present invention is as follows: an automatic quantitative gavage drug delivery device for animals used in traditional Chinese medicine pharmacology experiments, comprising a base plate, a box body fixedly connected to the base plate, and a fixing component for fixing the animal provided in the box body.

[0007] A channel is opened at the bottom of the box, and auxiliary components for assisting in fixing the animals are arranged in the channel.

[0008] A driving component for driving the fixed component to move is provided outside the box.

[0009] A drug administration component for gavage for animals is provided on the bottom plate.

[0010] The drug delivery component is provided with a limiting component for limiting the operation of the driving component.

[0011] The fixing assembly includes a rack, the rack is slidably matched with the inner wall of the box body, the rack is meshed with a first gear, and the first gear is rotatably connected to the inner wall of the box body.

[0012] The bottom of the rack passes through the box body and extends into the channel to be fixedly connected with a fixing plate, and the bottom of the fixing plate is symmetrically fixedly connected with retractable claws.

[0013] The top of the rack passes through the box body and extends to the outside of the box body, where an inflation component for inflating the auxiliary component is provided.

[0014] The technical principle of the above solution is as follows: the drive assembly drives the first gear to rotate, which in turn drives the rack to slide vertically within the housing. The sliding of the rack drives the fixing plate to move up and down, thereby securing the animal's body. The up and down movement of the fixing plate drives the claw to move up and down, thereby securing the animal's head.

[0015] The auxiliary component is inflated through the inflation component to further secure the animal. The animal is gavaged through the drug administration component. The driving component is restrained through the restraint component.

[0016] The above scheme has the following beneficial effects:

[0017] 1. The present invention can stably drive the fixing plate to move up and down through the meshing of the rack and the first gear, thereby fixing the animal's body through the fixing plate to ensure that the animal maintains a fixed posture during the drug administration process. The claws are used to fix the animal's head, reducing the impact of the animal's head swinging on the drug administration effect.

[0018] 2. The present invention further enhances the fixation effect by linking the inflatable component with the auxiliary component, and reduces the disorderly movement of animals due to resistance.

[0019] Furthermore, the first gear is meshed with a second gear, and the second gear is rotatably connected to the inner side wall of the box body away from the first gear.

[0020] The drive assembly includes a drive member and a controller, both of which are fixedly connected to the outside of the box. The controller is used to control the operation of the drive member. The output shaft of the drive member extends through the box to the box and is fixedly connected to the third gear. The third gear is fixedly connected to the first connecting rod on the side away from the drive member, and the end of the first connecting rod away from the third gear is fixedly connected to the middle of the second gear.

[0021] Beneficial effect: The output shaft of the driving member transmits power to the second gear through the third gear and the first connecting rod, and then drives the first gear to rotate through the second gear, thereby driving the rack to move up and down, which is beneficial to enhance the stability and accuracy of the transmission process.

[0022] Furthermore, the auxiliary component includes several airbags, which are fixedly connected to the side walls of the channel. The airbags are each provided with a first air inlet and a first air outlet. The first air inlet and the first air outlet are each fixedly connected to an electromagnetic valve, and the controller is used to control the opening and closing of the electromagnetic valve.

[0023] Beneficial Effects: Solenoid valves are installed at both the first air inlet and the first air outlet of the airbag. The controller precisely regulates the airbag pressure by controlling the opening and closing of the solenoid valves, thereby assisting in securing the animal. This design not only enhances the securing effect but also reduces mechanical pressure on the animal.

[0024] Furthermore, the inflation component includes a piston cylinder, which is fixedly connected to the outer wall of the box body, and has a second air inlet and a second air outlet. The second air inlet and the second air outlet are fixedly connected with a one-way valve, and the first air inlet is connected to the second air outlet.

[0025] A piston head is slidably fitted in the piston cylinder, a push rod is fixedly connected to a side of the piston head away from the second air inlet, and an end of the push rod away from the piston head is fixedly connected to the rack.

[0026] Beneficial effect: When the rack moves up and down, the push rod drives the piston head to slide in the piston cylinder, and the flow direction of the gas is controlled by the one-way valve to ensure that the airbag can be stably inflated.

[0027] Furthermore, the medication component includes a telescopic member and a bracket, both of which are fixedly connected to the base plate, a medication syringe is detachably connected to the bracket, and an output shaft of the telescopic member is in contact with the medication syringe.

[0028] Beneficial effects: By fixing the dosing syringe on the bracket, the output shaft of the telescopic member is used to push the dosing syringe to administer the drug to the animal by gavage, and the staff can control the dosing speed of the dosing syringe by the telescopic speed of the telescopic member.

[0029] Furthermore, an electromagnet is fixedly connected to the output shaft of the telescopic member, and the controller is used to control the opening and closing of the electromagnet.

[0030] The limiting component includes a limiting tooth, which is rotatably matched with the inner wall of the box body. A torsion spring is sleeved on the limiting tooth, one end of the torsion spring is fixedly connected to the inner wall of the box body, and the other end of the torsion spring is fixedly connected to the limiting tooth.

[0031] The limiting tooth is engaged with the third gear, the limiting rod is hinged on the top of the limiting tooth, the end of the limiting rod away from the limiting tooth is hinged on the second connecting rod, and the end of the second connecting rod away from the limiting rod passes through the box and is magnetically connected to the electromagnet.

[0032] Beneficial effect: The electromagnet is activated to drive the second connecting rod to move with the telescopic part, so that the limit tooth and the third gear are always engaged, which is beneficial to reduce the resistance of the animal and the loosening of the fixing plate. When the electromagnet is turned off, the torsion spring disengages the limit tooth and the third gear, and the animal can be unfixed.

[0033] Furthermore, a flexible layer is fixedly connected to the bottom of the fixing plate.

[0034] Beneficial Effects: The flexible layer at the bottom of the fixation plate reduces mechanical pressure on the animal and improves comfort during fixation. The flexible material conforms to the animal's surface, preventing skin damage or discomfort caused by overtightening. Furthermore, the flexible layer increases friction between the fixation plate and the animal, reducing slippage caused by resistance and further enhancing fixation effectiveness.

[0035] Furthermore, a lighting lamp is fixedly connected to one side of the box.

[0036] Beneficial Effects: The lighting provides uniform light, preventing operational errors or animal injuries caused by insufficient light. It also improves the visibility of the experimental environment, allowing researchers to monitor the device's operation and the animals' reactions in real time, identifying problems and making adjustments promptly.

[0037] Furthermore, the surface of the medication syringe is engraved with scales.

[0038] Beneficial Effects: The scale design on the surface of the drug cartridge allows the experimenter to precisely control the dosage, avoiding experimental deviations caused by operational errors. The scale is clear and intuitive, and can display the remaining amount of medicine in real time, making it easy to adjust the dosage and speed.

[0039] Furthermore, the surface of the airbag is engraved with anti-slip texture.

[0040] Beneficial Effects: The anti-slip texture on the airbag surface increases friction with the animal's body surface, preventing the animal from sliding due to resistance. The anti-slip texture effectively improves fixation, reduces animal movement during fixation, and ensures smooth drug delivery.

[0041] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following is further described in detail through specific implementation methods:

[0047] Example 1:

[0048] As attached Figure 1-Figure 3 As shown: an automatic quantitative gavage drug delivery device for animals used in traditional Chinese medicine pharmacology experiments, comprising a base plate 1, a box body 2 fixedly connected to the base plate 1 by bolts, and a fixing component for fixing the animal provided in the box body 2.

[0049] A channel is provided at the bottom of the box body 2, and auxiliary components for assisting in fixing the animal are provided in the channel.

[0050] A driving component for driving the fixed component to move is provided outside the box body 2.

[0051] The bottom plate 1 is provided with a drug administration component for gavage for animals.

[0052] The drug delivery component is provided with a limiting component for limiting the operation of the driving component.

[0053] like Figure 2 As shown, the fixing assembly includes a rack 6, which is slidably matched with the inner wall of the box body 2, and the rack 6 is engaged with a first gear 17, which is rotatably connected to the inner wall of the box body 2.

[0054] The bottom of the rack 6 passes through the box body 2 and extends into the channel where it is fixedly connected with a fixing plate 16 by bolts. The bottom of the fixing plate 16 is symmetrically fixedly connected with a retractable claw 14 by screws.

[0055] The top of the rack 6 passes through the box body 2 and extends to the outside of the box body 2 where an inflation component for inflating the auxiliary component is provided.

[0056] The first gear 17 is meshed with a second gear 18 , and the second gear 18 is rotatably connected to the inner wall of the box body 2 on a side away from the first gear 17 .

[0057] The driving assembly includes a driving member and a controller. In this embodiment, the driving member is selected as a driving motor 7. The driving motor 7 and the controller are both bolted to the outside of the box body 2. The controller is used to control the operation of the driving motor 7. The output shaft of the driving motor 7 passes through the box body 2 and extends to the box body 2 and is bolted to the third gear 21. The third gear 21 is bolted to the side away from the driving motor 7 with a first connecting rod 23. The end of the first connecting rod 23 away from the third gear 21 is bolted to the middle of the second gear 18.

[0058] like Figure 3 As shown, the auxiliary component includes several air bags 15, which are fixedly connected to the side wall of the channel with screws. A first air inlet and a first air outlet are opened in the air bags 15. The first air inlet and the first air outlet are fixedly connected with solenoid valves by screws, and the controller is used to control the opening and closing of the solenoid valves.

[0059] The inflation assembly includes a piston cylinder 3, which is fixedly connected to the outer wall of the box body 2 with bolts. A second air inlet and a second air outlet are opened in the piston cylinder 3. The second air inlet and the second air outlet are both fixedly connected with a one-way valve with screws, and the first air inlet is connected to the second air outlet.

[0060] A piston head 4 is slidably fitted in the piston cylinder 3 , and a push rod 5 is fixedly connected to the side of the piston head 4 away from the second air inlet by bolts, and an end of the push rod 5 away from the piston head 4 is fixedly connected to the rack 6 by bolts.

[0061] like Figure 1 As shown, the medication assembly includes a telescopic part and a bracket 13. In this embodiment, the telescopic part is selected as an electric telescopic rod 11. The electric telescopic rod 11 and the bracket 13 are both bolted to the base plate 1. The medication syringe 12 is detachably connected to the bracket 13, and the output shaft of the electric telescopic rod 11 is in contact with the medication syringe 12.

[0062] The output shaft of the electric telescopic rod 11 is fixedly connected with an electromagnet 10 by screws, and the controller is used to control the opening and closing of the electromagnet 10.

[0063] The limiting component includes a limiting tooth 20, which rotates with the inner wall of the box body 2. A torsion spring 22 is sleeved on the limiting tooth 20. One end of the torsion spring 22 is fixedly connected to the inner wall of the box body 2 with a screw, and the other end of the torsion spring 22 is fixedly connected to the limiting tooth 20 with a screw.

[0064] The limiting tooth 20 is engaged with the third gear 21. The limiting rod 19 is hinged to the top of the limiting tooth 20. The end of the limiting rod 19 away from the limiting tooth 20 is hinged to the second connecting rod 9. The end of the second connecting rod 9 away from the limiting rod 19 passes through the box 2 and is magnetically connected to the electromagnet 10.

[0065] The specific implementation process is as follows: first, the base plate 1 is placed on the experimental table, and then the staff places the animals in the channel. Figure 2 and Figure 3 For example, under the elastic force of the torsion spring 22, the limit tooth 20 and the third gear 21 will be out of engagement. The staff controls the drive motor 7 to start through the controller. After the drive motor 7 is started, it will drive the third gear 21 to rotate. The third gear 21 will drive the second gear 18 to rotate through the connecting rod 23. The rotation of the second gear 18 will drive the first gear 17 to rotate. Since the first gear 17 is engaged with the rack 6, when the first gear 17 rotates, it will drive the rack 6 to slide up and down along the inner wall of the box body 2.

[0066] Combine Figure 1 As shown, when the rack 6 slides downward, the fixing plate 16 will drop as the rack 6 slides downward. At this time, the fixing plate 16 will squeeze the back of the animal, thereby fixing the back of the animal. As the fixing plate 16 drops, the claws 14 will restrict the head of the animal, thereby fixing the head of the animal.

[0067] As the rack 6 slides downward, it also drives the push rod 5 downward, and the downward movement of the push rod 5 drives the piston head 4 downward in the piston cylinder 3. At this time, the gas in the piston cylinder 3 enters the airbag 15 through the second air outlet, causing the airbag 15 to expand. After the airbag 15 expands, it assists in fixing the animal's body on both sides, thereby enhancing the animal's fixation effect, reducing the animal's movement during the experiment, and improving the accuracy of the experiment.

[0068] After the animal is fixed, the staff can turn off the drive motor 7, which has a self-locking function, and the fixing plate 16 stops descending.

[0069] The staff can remove the dosing syringe 12 and fill it with medicine, and then fix the dosing syringe 12 on the bracket 13. The staff can then start the electric telescopic rod 11 through the controller, and use the extension of the electric telescopic rod 11 to push the dosing syringe 12 so that the medicine in the dosing syringe 12 can be fully poured into the animal's stomach.

[0070] The staff can adjust the extension and retraction rate of the electric telescopic rod 11 through the controller, thereby adjusting the intragastric administration rate.

[0071] Although the driving motor 7 has been turned off, during the oral administration experiment, the animal's constant struggle will still cause the fixing plate 16 to slide, resulting in a weakened fixing effect of the fixing plate 16 on the animal, thereby affecting the experimental effect.

[0072] Therefore, when the electric telescopic rod 11 is started, the staff can control the electromagnet 10 to start through the controller, and the electromagnet 10 will generate a magnetic attraction to the second connecting rod 9 after being started.

[0073] As the telescopic rod 11 extends, the second connecting rod 9 moves with the extension of the telescopic rod 11 under the influence of the magnetic attraction of the electromagnet 10. At this time, the second connecting rod 9 pushes the limiting rod 19 to squeeze the limiting tooth 20, causing the limiting tooth 20 to mesh with the third gear 21. The limiting tooth 20 and the drive motor 7 then restrict the third gear 21, preventing it from rotating.

[0074] When the third gear 21 cannot rotate, the second gear 18, the first gear 17 and the rack 6 cannot move, thereby ensuring that the fixing plate 16 cannot move, thereby improving the fixing effect on the animal.

[0075] Through the self-locking function of the driving motor 7 after being turned off and the engagement of the limiting tooth 20 with the third gear 21, it can be fully ensured that the rack 6 and the fixing plate 16 will not loosen due to the struggle of the animal, thereby further ensuring the safety, stability and experimental accuracy during the animal gavage drug administration experiment.

[0076] After the gavage administration is complete, the staff can use the controller to turn off the electromagnet 10. Once the electromagnet 10 is turned off, the elastic action of the torsion spring 22 causes the limit tooth 20 to spring upward, disengaging the third gear 21 from the limit tooth 20. The second gear 18, the first gear 17, and the rack 6 resume their motion. The staff can then use the controller to reverse the drive motor 7, driving the rack 6 upward. The claws 14 on the fixing plate 16 gradually release, and the animal is finally removed, completing the experiment.

[0077] Example 2:

[0078] The difference from the above embodiment is that a flexible layer is bonded to the bottom of the fixing plate 16 , and in this embodiment, the flexible layer is a sponge layer.

[0079] The specific implementation process is as follows: When the rack 6 drives the fixing plate 16 downward, the sponge layer directly contacts the animal's back. The sponge layer can adapt to the natural curve of the animal's back, evenly distributing pressure to avoid causing localized pressure or discomfort to the animal. The sponge layer can closely fit the animal's body, reducing the animal's movement space during the fixation process and improving the stability of the fixation.

[0080] Example 3:

[0081] like Figure 1 As shown, the difference from the above embodiment is that a lighting lamp 8 is fixedly connected to one side of the box body 2 by screws.

[0082] The specific implementation process is as follows: the lighting lamp 8 can provide a sufficient lighting environment, which enables the staff to clearly observe the position of the animal, the insertion depth of the medication syringe 12 and the status of the airbag 15 to ensure the accuracy of the operation.

[0083] Example 4:

[0084] The difference from the above embodiment is that the surface of the medication syringe 12 is engraved with scales.

[0085] The specific implementation process is as follows: The scale design allows staff to accurately control the dosage, avoiding experimental errors caused by inaccurate dosage. The scale can also be used to monitor the progress of drug injection to ensure a smooth drug delivery process.

[0086] Example 5:

[0087] The difference from the above embodiment is that the surface of the airbag 15 is engraved with anti-slip texture.

[0088] The specific implementation process is as follows: The anti-slip texture effectively prevents the animal from sliding during the fixation process, improving the stability and safety of the fixation. The stable fixation effect helps the experiment proceed smoothly, reducing the interruption or repeated operation caused by animal displacement.

[0089] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
