[0001] This utility model relates to the field of animal treatment device technology, and in particular to a gavage device. Background Technology

[0002] Animal husbandry refers to the production process of using domesticated animals such as livestock and poultry to convert plant energy from pasture and feed into animal energy, in order to obtain livestock products such as meat, eggs, and milk. It is a crucial link in the exchange of materials between humans and nature and an important component of agriculture.

[0003] Oral gavage, as a non-invasive method of drug administration, mimics clinical oral administration and is the most common way for drugs to enter the body, making it a frequently used veterinary treatment method for livestock. However, with existing gavage devices, to prevent livestock from biting the tube and blocking drug delivery, the animal's mouth needs to be manually pried open throughout the gavage process. This is very laborious, and the animal's tongue may obstruct the insertion due to discomfort from the tube, making insertion time-consuming and laborious, which is detrimental to the animal's treatment. Utility Model Content

[0004] The purpose of this application is to provide a gavage device to solve the problem mentioned in the background art that, in order to prevent livestock from biting the gavage tube and blocking the administration of medicine, the mouth of the livestock needs to be manually pried open during the entire gavage process. This operation is very laborious, and the animal's tongue may block the insertion of the gavage tube due to its own discomfort with the tube. This makes the insertion of the gavage tube time-consuming and laborious, which is not conducive to the treatment of livestock.

[0005] To achieve the above objectives, this application provides the following technical solution: a gavage device, comprising a fixed cylinder and a gavage tube, wherein a connector is fixed to the drug inlet end of the gavage tube, and a pushing component is provided on the connector for pushing the drug solution into the gavage tube; a lower dental sleeve is fixed to the bottom of the fixed cylinder, and a bolt is inserted into the top of the fixed cylinder, the fixed cylinder being threadedly connected to the bolt; a support rod is fixed to the top of the bolt, and an upper dental sleeve is rotatably connected to the top of the support rod via a bearing; a sleeve is fixed to the top of the lower dental sleeve, and a guide rod is fixed to the bottom of the upper dental sleeve; the guide rod slides in cooperation with the inner wall of the sleeve, and a limit rod is fixed to the outer wall of the guide rod; a limiting groove for sliding the limit rod is provided on the sleeve; and a tongue depressor is fixed to the lower dental sleeve.

[0006] Furthermore, rubber pads are fixed to the inner sides of both the lower and upper dental braces, and protective rods are fixed to the bottom of the lower dental brace and the top of the upper dental brace.

[0010] Furthermore, the pushing component includes a medicine storage cylinder, which is threadedly connected to a connector. A dosing pipe is fixedly connected to the side wall of the medicine storage cylinder, and a pipe cap is threadedly connected to the dosing pipe. A piston is slidably disposed inside the medicine storage cylinder, and a push rod is fixedly disposed on the outside of the piston.

[0011] Furthermore, two ear plates are fixed to the outer wall of the medicine storage cylinder.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, after manually opening the animal's mouth, the lower tooth clip can be secured to the animal's lower teeth, and the upper tooth clip to the animal's upper teeth. By using a wrench to turn the bolt, the combined length of the bolt and the fixing cylinder can be adjusted, so that the distance between the lower and upper tooth clips can be adjusted as needed. This opens the animal's mouth, and only the animal's head needs to be fixed. The gavage tube can then be slowly inserted into the animal's stomach through the opened mouth to administer the medication. During this process, the tongue depressor can hold down the animal's tongue to prevent it from obstructing the insertion of the gavage tube, making the gavage administration process more convenient and labor-saving.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Reference Figure 1-5 The illustrated gavage device includes a fixed cylinder 1 and an enema tube 2. The enema tube 2 is equipped with a scale to facilitate veterinarians in determining the insertion depth during insertion. A connector 3 is fixed to the drug inlet end of the enema tube 2, and a pushing component is provided on the connector 3 for pushing the drug solution into the enema tube 2. A lower dental sleeve 4 is fixed to the bottom of the fixed cylinder 1, and a bolt 5 is inserted into the top of the fixed cylinder 1. The fixed cylinder 1 and the bolt 5 are threaded together. A support rod 6 is fixed to the top of the bolt 5, and an upper dental sleeve 7 is rotatably connected to the top of the support rod 6 via a bearing. A sleeve is fixed to the top of the lower dental sleeve 4. The bottom of the tube 8 and the upper dental sleeve 7 is fixed with a guide rod 9. The guide rod 9 slides with the inner wall of the tube 8, and the outer wall of the guide rod 9 is fixed with a limiting rod 10. The tube 8 is provided with a limiting groove for the limiting rod 10 to slide. The limiting rod 10 is used to prevent the tube 8 from completely separating from the guide rod 9, the fixing cylinder 1 from the bolt 5. The lower dental sleeve 4 is fixed with a tongue depressor 11. The top of the tongue depressor 11 is fixed with a fixing block 14. The middle of the fixing block 14 is provided with a tube hole. The tube hole on the fixing block 14 is used to make it easier to insert the gavage tube 2 into the mouth of the livestock.

[0024] After manually opening the animal's mouth, the lower tooth clip 4 can be secured to the animal's lower teeth, and the upper tooth clip 7 can be secured to the animal's upper teeth. By using a wrench to turn the bolt 5, the combined length of the bolt 5 and the fixing cylinder 1 can be adjusted, so that the distance between the lower tooth clip 4 and the upper tooth clip 7 can be adjusted as needed. This opens the animal's mouth, and only the animal's head needs to be fixed. The septic tube 2 can then be slowly inserted into the animal's stomach through the opened mouth to administer the medication. During this process, the tongue depressor 11 can press down on the animal's tongue to prevent it from obstructing the insertion of the septic tube 2.

[0025] Rubber pads 12 are fixed to the inner sides of both the lower toothed bracket 4 and the upper toothed bracket 7. The use of rubber pads 12 can protect the teeth of livestock when their mouths are opened. Protective bars 13 are fixed to the bottom of the lower toothed bracket 4 and the top of the upper toothed bracket 7. The use of protective bars 13 can prevent the edges of the lower toothed bracket 4 or the upper toothed bracket 7 from scratching the mouth of livestock.

[0026] The gavage tube 2 has a guide block 15 fixed at the dispensing end. The guide block 15 has a delivery channel in the middle. The use of the guide block 15 makes the gavage tube 2 easier to insert into the stomach of the livestock. The gavage tube 2 is equipped with a one-way valve. The use of the one-way valve makes the gavage tube 2 only allow one-way flow from the connector 3 to the guide block 15.

[0027] The push assembly includes a medicine storage cylinder 16, which is threadedly connected to the connector 3. A dosing pipe 17 is fixedly connected to the side wall of the medicine storage cylinder 16. A pipe cap 18 is threadedly connected to the dosing pipe 17. A piston 19 is slidably arranged inside the medicine storage cylinder 16. A push rod 20 is fixed to the outside of the piston 19. Two ear plates 21 are fixed to the outer wall of the medicine storage cylinder 16.

[0028] Unscrew the cap 18 and use the push rod 20 to pull the piston 19 outward, making the process of adding medicine into the storage cylinder 16 along the dosing tube 17 smoother. The cap 18 can block the dosing tube 17, making it easier to administer medicine to the animal's stomach when the push rod 20 pushes the piston 19 to squeeze the medicine out of the storage cylinder 16. The two ear plates 21 can provide the veterinarian with the force points needed to push the push rod 20, making it easier for the veterinarian to perform the drug administration operation.

[0029] Working principle of this utility model:

[0030] First, the animal's mouth is opened by the animal's handler. Then, the veterinarian places the lower tooth clip 4 on the animal's lower teeth and the upper tooth clip 7 on the animal's upper teeth. The bolt 5 is turned with a wrench to adjust the combined length of the bolt 5 and the fixing cylinder 1, so that the distance between the lower tooth clip 4 and the upper tooth clip 7 is increased. This can open the animal's mouth to near its maximum value, so that the animal cannot spit out the lower tooth clip 4 and the upper tooth clip 7 by continuing to open its mouth. The tongue depressor 11 will press down on the animal's tongue during the installation of the lower tooth clip 4 and the upper tooth clip 7 to prevent the tongue from blocking the subsequent insertion tube. After that, the animal's head is clamped and fixed with a tool so that its head cannot move freely.

[0031] Take out the gavage tube 2, fix the connector 3 on the gavage tube 2 to the medicine storage cylinder 16, unscrew the tube cap 18, insert the medicine upside down into the medicine addition tube 17, pull the push rod 20 outward, so that the push rod 20 drives the piston 19 to move outward, so that the medicine can be drawn into the medicine storage cylinder 16. After the medicine is added, use the tube cap 18 to close the medicine addition tube 17 again. After passing the gavage tube 2 through the tube hole on the fixing block 14, the gavage tube 2 is inserted into the stomach of the livestock through the mouth. Then, with the force provided by the two ear plates 21, the push rod 20 can be pushed to squeeze the piston 19 inward, so that the piston 19 pushes the medicine in the medicine storage cylinder 16 to be delivered to the stomach of the livestock along the gavage tube 2, thus completing the administration of medicine to the livestock.

[0032] 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.
