Description

Technical Field

[0001] This utility model relates to the field of gavage equipment technology, and in particular to an automated gavage device suitable for small animals. Background Technology

[0002] In scientific research and medical experiments, gavage is often required for small animals. This is an important method for precise drug administration or nutrient delivery. When testing drug efficacy or studying nutrient metabolism, gavage ensures accurate dosage, avoids deviations caused by animals' self-feeding, helps researchers obtain reliable data, and promotes the output of research results in medicine and other fields.

[0003] The basic structure of this automated gavage device includes: a reservoir for storing the gavage fluid; a peristaltic pump that uses rollers to squeeze the tubing, generating suction and thrust to precisely deliver the fluid; a gavage needle to introduce the fluid into the animal's body; and a support frame to stabilize the animal. The control system coordinates all components to complete the gavage process quickly and accurately according to the set dosage.

[0004] In existing technologies, some automated gavage devices increase risks during use because they cannot adapt to the physiological characteristics of different small animals. For sensitive small animals, the excessively fast flow rate may cause choking or esophageal damage. The inability to quickly change the delivery head reduces the efficiency of the equipment. When switching between different animal experiments or when the delivery head is damaged, the experimental process is delayed. Therefore, an automated gavage device suitable for small animals is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automated gavage device suitable for small animals, comprising a base 1. The base 1 is sturdy and firmly supports the components above. A filling device 2 is fixedly connected to the top right side of the base 1, which can position the filling device 2. Both the left and right ends of the filling device 2 are fixedly connected to partitions 3, which divide the space into distinct functional areas to prevent the liquid from flowing randomly inside. A motor 4 is fixedly connected to the right side of the filling device 2, which is the key to power output. A rotating rod 5 is fixedly connected to the drive end of the motor 4, which can drive the rotating rod 5 to rotate. The outside of the rotating rod 5 is rotatably connected to the inside of the two partitions 3, which can provide a fulcrum for the rotating rod 5. Multiple blades 6 are fixedly connected to the outside of the rotating rod 5. When the rotating rod 5 rotates, it can drive the blades 6 to rotate. The left and right ends of the multiple blades 6 are respectively in contact with the adjacent ends of the two partitions 3, which can accelerate or slow down the liquid inside the filling device 2.

[0031] A suction pump 7 is fixedly connected to the rear end of the filling device 2. The suction pump 7 can extract the liquid inside the filling device 2. A connecting pipe 8 is fixedly connected to the output end of the suction pump 7. The liquid can be transferred to the inside of the connecting pipe 8 through the suction pump 7. A transfer head 9 is detachably connected to the rear end of the connecting pipe 8. The transfer head 9 is a tool for filling small animals. Both the outer top ends of the connecting pipe 8 and the transfer head 9 are provided with L-shaped grooves 10. The subsequent workpiece can be locked in place through the L-shaped grooves 10. A sealing gasket 11 is fixedly connected inside the connecting pipe 8. The front end of the transfer head 9 is connected to the sealing gasket. The rear end of 11 is in contact with each other. The connecting pipe 8 and the external of the transmission head 9 are slidably connected by a sliding sleeve 12. The sliding sleeve 12 can slide on the outside of the connecting pipe 8 and the transmission head 9. Two locking balls 13 are fixedly connected inside the sliding sleeve 12. When the sliding sleeve 12 moves, it can drive the locking balls 13 to move. The external of the locking balls 13 is slidably connected inside the L-shaped groove 10. When the locking balls 13 move to a specific position inside the L-shaped groove 10, the connecting pipe 8 and the transmission head 9 can be positioned relative to each other. The sealing gasket 11 can seal the connection between the connecting pipe 8 and the transmission head 9 to prevent liquid leakage.

[0032] Reference Figure 1 and Figure 2A binding assembly for improving the comfort of small animals is fixedly connected to the top right side of the base 1. The binding assembly includes a housing 14, which provides a base for subsequent installation. The bottom of the housing 14 is fixedly connected to the top right side of the base 1. Restriction grooves 15 are provided at both ends of the housing 14. The restriction grooves 15 can lock the subsequent workpiece. A cylinder 16 is fixedly connected to the front end of the housing 14. A crossbar 17 is fixedly connected to the drive end of the cylinder 16. The cylinder 16 can push the crossbar 17 to move. Limiting rings 18 are fixedly connected to both ends of the crossbar 17. When the crossbar 17 moves, it can drive the limiting rings 18 to move, and the limiting rings 18 can limit the movement position of the crossbar 17.

[0033] The left and right ends of the crossbar 17 are slidably connected to the inside of two limiting grooves 15. The limiting grooves 15 provide the crossbar 17 with a moving position, so that the crossbar 17 can only move in a straight line following the limiting grooves 15. The left and right ends of the crossbar 17 are rotatably connected to adjusting rods 19. When the crossbar 17 moves, it can pull the bottom of the adjusting rods 19 to move. The top of the two adjusting rods 19 is rotatably connected to a placement plate 20. When the bottom of the adjusting rods 19 moves, the placement plate 20 can be angled. The top of the placement plate 20 is fixedly connected to a tension band 21. The tension band 21 is made of rubber. The rubber material can improve the comfort when binding small animals. By adjusting the angle, it is easier to put the tube into the mouth of the small animal. The bottom rear end of the placement plate 20 is rotatably connected to two positioning rods 22. The positioning rods 22 can provide stable performance for the placement plate 20. The inside of the two positioning rods 22 is rotatably connected to the outside of the crossbar 17. The crossbar 17 can provide a stable effect for the positioning rods 22.

[0034] Working principle: The core of the equipment, the filling device 2, has an ingenious internal structure. The motor 4 drives the rotating rod 5 to rotate at high speed. The rotating rod 5 passes through two partitions 3 and is flexibly connected to them. Multiple blades 6 installed on the rotating rod 5 rotate synchronously. They fit tightly against the partitions 3, thus creating a strong suction force inside the filling device 2, which promotes the smooth flow of the liquid to be administered to the extraction pump 7. The speed of the motor 4's rotation allows the liquid inside the filling device 2 to be transferred out according to the speed of the motor 4, thereby improving the comfort of the small animal during gavage and avoiding harm to the small animal during gavage.

[0035] The pump 7 plays a crucial role in conveying the liquid. The liquid pumped by the pump 7 is transferred to the transfer head 9 via the connecting pipe 8. The connecting pipe 8 and the L-shaped groove 10 at the outer top of the transfer head 9 cooperate with the retaining ball 13 inside the sliding sleeve 12 to achieve a convenient and detachable connection. When the transfer head 9 needs to be replaced, the sliding sleeve 12 is rotated so that the retaining ball 13 inside the sliding sleeve 12 can match the straight part of the L-shaped groove 10, thus removing the transfer head 9. The same principle applies during installation. First, the L-shaped groove 10 on the transfer head 9 is paired with the retaining ball 13 inside the sliding sleeve 12 so that the retaining ball 13 is aligned with the L-shaped groove 10. Then, the transfer head 9 is inserted, and the sliding sleeve 12 is rotated so that the retaining ball 13 inside the sliding sleeve 12 can engage with the L-shaped groove 10, thus achieving a positioning effect. The sealing gasket 11 ensures the sealing of the connection and prevents liquid leakage.

[0036] Regarding the restraint components that enhance the comfort of small animals, a shell 14 serves as the basic support. A cylinder 16 is activated upon command, pushing a crossbar 17 to slide horizontally within a limiting groove 15. Limiting rings 18 at both ends of the crossbar 17 ensure stable movement. Adjusting rods 19 at both ends of the crossbar 17 move in tandem, causing the placement tray 20 connected to it at the top to change its angle and precisely adjust the animal's position. The rubber tension band 21 on the placement tray 20, with its softness and elasticity, gently restrains the animal, preventing it from escaping and minimizing discomfort. Two positioning rods 22 at the bottom rear end are rotatably connected to the crossbar 17, enhancing the stability of the placement tray 20 during adjustment. This comprehensive approach ensures the animal's safety and comfort during gavage, facilitating the smooth and precise completion of the entire gavage process and laying the foundation for the efficient conduct of small animal experiments.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
