[0002] In biomedical research and animal experiments, precise and efficient drug administration to laboratory mice is a crucial technical requirement. Traditional drug administration methods often rely on manual operation, which is not only inefficient but also makes it difficult to ensure the accuracy and consistency of drug delivery. To address this issue, this drug administration device employs a series of innovative designs aimed at improving the accuracy and efficiency of drug administration to laboratory mice. Made of food-grade transparent plastic, it ensures the hygienic safety of drug storage while facilitating observation of the remaining drug volume. The volume scale is displayed in intuitive milliliters, providing convenience for precise control of the drug dosage. The drug storage bottle expands outward and returns to its original shape after being squeezed, making the drug administration process smoother and ensuring that the storage bottle automatically returns to its original shape after each administration, facilitating reuse. The hemispherical design at the tip of the drug administration tube facilitates insertion into the laboratory mouse's mouth, while the reinforced fixing plate ensures the stability and fixation of the drug administration tube during the administration process, reducing operational errors.
[0003] However, when administering medication to experimental mice using the experimental drug feeding device, the feeding tube of the device needs to be inserted into the mouse's mouth. The medication is then squeezed into the mouse's mouth through the feeding tube. During the medication administration process, the feeding tube needs to remain inserted in the mouse's mouth. When mice are forcibly fed medication, they are easily startled and may quickly close their mouths, which could cause the mice to bite the person administering the medication. Utility Model Content
[0004] The purpose of this invention is to provide a drug feeding device for laboratory mice, in order to solve the problem mentioned in the background art that during the drug feeding process, it is necessary to keep the drug feeding tube inserted in the mouth of the laboratory mouse. When the laboratory mouse is forcibly fed with drugs, it is easy to be startled and quickly close its mouth, which may cause the laboratory mouse to bite the person feeding the drugs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a drug feeding device for laboratory mice, comprising a drug storage bottle and a bottle mouth disposed at the top of the drug storage bottle, wherein a sealing plug is inserted into the bottle mouth, and a drug feeding tube is inserted and fixed into the sealing plug, wherein the top of the drug feeding tube is hemispherical, and a drug feeding protection device is disposed on the outside of the drug feeding tube.

The bottom of the soft protective plug is fixed with a metal fixing plate, which is fitted onto the outside of the medication feeding tube.
[0007] Preferably, the soft protective plug is made of food-grade soft silicone, the top of the soft protective plug is provided with a tapered bevel, and the soft protective plug and the metal fixing piece can move up and down outside the feeding tube.
[0008] Preferably, the medication feeding protection device further includes an L-shaped push-pull rod and a push-pull handle. The top left end of the L-shaped push-pull rod is fixedly connected to the right end of the metal fixing plate by welding. A push-pull handle is provided at the bottom right end of the L-shaped push-pull rod, and the push-pull handle is located on the right side of the outer wall of the right end of the medicine storage bottle.
[0009] Preferably, the medicine storage bottle and the bottle mouth are made of food-grade transparent plastic through a blow molding process, and the medicine storage bottle can expand outward and return to its original position after being squeezed due to the elasticity of the material.
[0010] Preferably, the outer wall of the medicine storage bottle is also provided with a capacity scale, which protrudes outward from the medicine storage bottle, and the capacity scale is measured in milliliters.
[0011] Preferably, a reinforcement fixing piece is also fixed to the lower outer side of the center of the feeding tube, and the bottom end of the reinforcement fixing piece is fixedly connected to the sealing fixing plug by an adhesive.

[0013] Compared with the prior art, this utility model provides a drug feeding device for laboratory mice, which has the following beneficial effects:
[0014] This invention adds a novel feeding protection device to the outside of the feeding tube of the experimental mouse feeding device. After the tip of the feeding tube is inserted into the mouth of the experimental mouse, the main body of the feeding protection device can be pushed into the mouth of the experimental mouse by pushing and pulling the handle. This can prevent the experimental mouse from closing its mouth and forcibly biting the feeder during the feeding process. Because after the main body of the feeding protection device, i.e. the soft protective plug, is pushed into the mouth of the experimental mouse, the soft protective plug will forcibly open the mouth of the experimental mouse to prevent the experimental mouse from being startled and closing its mouth to bite the feeder during the feeding process. This can play a safety protection role for the feeder. Attached Figure Description

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.
[0020] This utility model provides, for example Figure 1-3 The device shown is a drug feeding device for laboratory mice, comprising a drug storage bottle 1 and a nozzle 3 at the top of the drug storage bottle 1. A sealing plug 4 is inserted into the nozzle 3, and a feeding tube 5 is inserted and fixed into the sealing plug 4. The top of the feeding tube 5 is hemispherical. The drug storage bottle 1 and the nozzle 3 are made of food-grade transparent plastic by blow molding. The drug storage bottle 1 can expand outward and return to its original position after being squeezed. The outer wall of the drug storage bottle 1 is also provided with a volume scale 2, which protrudes outward from the drug storage bottle 1 and is measured in milliliters. A reinforcement fixing piece 7 is also fixed to the lower outer side of the center of the feeding tube 5. The bottom end of the reinforcement fixing piece 7 is fixedly connected to the sealing plug 4 by an adhesive. The sealing plug 4 is made of food-grade elastic rubber. The sealing plug 4 and the bottle mouth 3 are press-fitted. When using this feeding device to feed drugs to experimental mice, the dosage of the drug solution needs to be determined first. Then, the drug solution is injected into the drug storage bottle 1 through the bottle mouth 3. Then, the sealing plug 4 needs to be inserted into the bottle mouth 3 until the sealing plug 4 is firmly inserted and fixed in the bottle mouth 3. Then, the experimental mice are prepared to be fed drugs. When feeding drugs, the feeding tube 5 needs to be inserted into the mouth of the experimental mouse. Then, the drug storage bottle 1 needs to be squeezed. This will squeeze the drug solution in the bottle through the feeding tube 5 into the mouth of the experimental mouse. This will make the experimental mouse swallow the drug solution in its mouth, thereby achieving the purpose of feeding drugs to the experimental mouse.
[0021] like Figure 1 and Figure 3 As shown, a feeding protection device 6 is provided on the outside of the feeding tube 5. The feeding protection device 6 includes a soft protective plug 8 and a metal fixing plate 9.

The metal fixing plate 9 is fixed to the bottom of the soft protective plug 8 and is sleeved on the outside of the feeding tube 5. The soft protective plug 8 is made of food-grade soft silicone, and the top of the soft protective plug 8 is set with a tapered bevel. The soft protective plug 8 and the metal fixing plate 9 can move up and down on the outside of the feeding tube 5. The feeding protection device 6 also includes an L-shaped push-pull rod 10 and a push-pull handle 11. The top left end of the L-shaped push-pull rod 10 is fixedly connected to the right end of the metal fixing plate 9 by welding. The bottom right end of the L-shaped push-pull rod 10 is provided with a push-pull handle 11. Located on the right side of the outer wall of the drug storage bottle 1, when using the drug feeding device to administer oral medication to experimental mice, it is necessary to first ensure that the metal fixing piece 9 at the bottom of the soft protective plug 8 is attached to the sealing fixing plug 4. Only in this way can the drug feeding tube 5 be properly inserted into the oral cavity of the experimental mouse for drug administration. After the drug feeding tube 5 is inserted into the oral cavity of the experimental mouse, the finger needs to be pressed against the push-pull handle 11, and the soft protective plug 8 is pushed towards the oral cavity of the experimental mouse through the push-pull handle 11 and the L-shaped push-pull rod 10 until the soft protective plug 8 is inserted into the oral cavity of the experimental mouse. The soft protective plug 8 will open the oral cavity of the experimental mouse by its own volume, preventing the experimental mouse from being startled during the drug administration process and closing its mouth and biting the drug feeder, thus protecting the drug feeder.
