Description

Technical Field

[0001] This utility model relates to the technical field of livestock medication, and in particular to a livestock quantitative medication device. Background Technology

[0002] Animal diseases are inevitable during the raising of livestock and poultry. Drug treatment is an important means of treating livestock and poultry. Due to the characteristics of animals, they are less cooperative when being given drugs. Therefore, forced administration is required. This necessitates the use of a drug administration device to assist veterinarians in administering drugs to animals. The quantitative control of the drug solution can save costs while maximizing the treatment effect on animals.

[0003] Existing livestock medication technologies, such as the prior art with application number CN202323468653.6, include a syringe, threaded rod, push rod, piston, medication outlet, threaded wire, hose, threaded sleeve, limiting groove, placement plate, movable groove, push plate, and protrusion. When the medication outlet is placed in the animal's mouth, the push plate is pushed, causing it to move towards the medication outlet. Through the engagement of the protrusion with the inclined surface of the movable plate, when the protrusion moves towards the medication outlet, the movable plate is pushed by the protrusion, causing the two movable plates to move away and push open the animal's upper and lower jaws, thereby protecting the medication outlet and preventing the animal from biting and damaging the medication device.

[0004] However, existing technology is not convenient for adjusting the amount of medication administered, which reduces its practicality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a livestock quantitative medication device that facilitates automatic quantitative medication administration and allows for easy adjustment of the medication dosage, thereby improving practicality and convenience.

[0006] This utility model discloses a livestock quantitative medication administration device, comprising a medication administration mechanism; it also includes a rebound mechanism, a quantitative adjustment mechanism, a medication dispensing mechanism, a limiting mechanism, and a pressure relief mechanism. The rebound mechanism is installed on the medication administration mechanism, the quantitative adjustment mechanism is installed on the rebound mechanism, the medication dispensing mechanism is installed on the medication administration mechanism, the limiting mechanism is installed on the medication dispensing mechanism, and the pressure relief mechanism is installed on the medication dispensing mechanism. The medication administration mechanism draws out the medication and administers it into the livestock's mouth. The rebound mechanism assists the medication administration mechanism in rebounding, the quantitative adjustment mechanism facilitates quantitative medication administration, the medication dispensing mechanism facilitates medication placement and replacement, and the limiting mechanism facilitates the control of the medication dispensing mechanism. The system features a limiting and fixing mechanism, a pressure relief mechanism to depressurize the dosing mechanism, a dispensing mechanism to extract and inject medication into the animal's mouth, a rebound mechanism to assist the dispensing mechanism in rebounding, reducing operator workload and improving convenience, a quantitative adjustment mechanism to facilitate quantitative medication dispensing and adjust the amount of medication dispensed, improving practicality, a dosing mechanism to facilitate medication placement and replacement, a limiting mechanism to limit and fix the dosing mechanism, improving stability, and a pressure relief mechanism to depressurize the dosing mechanism, allowing the medication to flow smoothly into the dispensing mechanism.

[0007] Preferably, the medication dispensing mechanism includes a syringe, a piston, a pull rod, a push plate, a hook plate, and a medication dispensing tube. The syringe has graduations on its outer wall. The piston is slidably mounted inside the syringe. The pull rod is rotatably mounted on the piston. The push plate is mounted on the outer end of the pull rod. The hook plate is mounted on the outer wall of the syringe. The medication dispensing tube is mounted on the syringe and has a first one-way valve. The medication dispensing mechanism is mounted on the syringe and has a second one-way valve. When medication needs to be drawn, with the assistance of a rebound mechanism, the pull rod pulls the piston to slide away from the medication dispensing tube inside the syringe. At this time, the first one-way valve in the medication dispensing tube closes, and the second one-way valve in the medication dispensing mechanism opens, allowing the medication in the medication dispensing mechanism to enter the syringe. Then, the push plate is pushed, causing the pull rod to push the piston to slide closer to the medication dispensing tube inside the syringe. At this time, the first one-way valve in the medication dispensing tube opens, and the second one-way valve in the medication dispensing mechanism closes, thus dispensing the medication from the syringe into the animal's mouth through the medication dispensing tube.

[0008] Preferably, the rebound mechanism includes a first auxiliary ring, a second auxiliary ring, and a rebound spring. The first auxiliary ring contacts the hook plate, the second auxiliary ring contacts the push plate, and the rebound spring connects the first and second auxiliary rings. The rebound spring is fitted onto the outside of the pull rod. When medication is to be drawn, the elasticity of the rebound spring pushes the push plate, causing the push plate to move relative to the hook plate. This, in turn, drives the pull rod to pull the piston in the syringe, which slides away from the medication tube. At this time, the first one-way valve in the medication tube is closed, and the second one-way valve in the medication mechanism is opened, allowing the medication in the medication mechanism to enter the syringe. Then, the push plate is pushed, causing the pull rod to push the piston in the syringe, which slides closer to the medication tube. At this time, the first one-way valve in the medication tube is opened, and the second one-way valve in the medication mechanism is closed, allowing the medication in the syringe to be injected into the animal's mouth through the medication tube.

[0009] Preferably, the quantitative adjustment mechanism includes an adjusting thread and a threaded T-shaped cylinder. The adjusting thread is located on the pull rod, and the threaded T-shaped cylinder is slidably installed inside the syringe. The threaded T-shaped cylinder is threadedly engaged with the adjusting thread on the pull rod. When medication needs to be drawn, the elasticity of the return spring pushes the push plate, causing the push plate to move relative to the hook plate. This, in turn, drives the pull rod to pull the piston in the syringe, causing it to slide away from the drug delivery tube until the threaded T-shaped cylinder contacts and is limited by the hook plate. At this point, the first one-way valve in the drug delivery tube closes, and the second one-way valve in the drug delivery mechanism opens, allowing the medication in the drug delivery mechanism to enter the syringe. Then, the push plate is pushed, causing... The pull rod pushes the piston to slide towards the injection tube inside the syringe. At this time, the first one-way valve in the injection tube opens and the second one-way valve in the drug delivery mechanism closes, thus injecting the drug in the syringe into the animal's mouth through the injection tube, thereby achieving quantitative drug delivery. When adjusting the amount of drug, first pull the first auxiliary ring, causing the return spring to contract. The first auxiliary ring moves away from the hook plate, exposing one end of the threaded T-shaped cylinder. By rotating one end of the threaded T-shaped cylinder, the pull rod moves relative to the threaded T-shaped cylinder due to the thread relationship, thereby adjusting the position of the piston, thus completing the adjustment of the quantitative drug delivery amount.

[0010] Preferably, the drug delivery mechanism includes a limiting cylinder, a drug-passing needle, a drug storage bottle, and a rubber stopper. The limiting cylinder is installed on the syringe, the drug-passing needle is installed inside the limiting cylinder, and a second one-way valve is provided inside the drug-passing needle. A rubber stopper is installed on the drug storage bottle, and the rubber stopper can be installed on the drug-passing needle. The drug-passing needle communicates with the inside of the syringe. First, the drug is added to the drug storage bottle for storage. When the drug storage bottle needs to be installed, the drug-passing needle is inserted through the rubber stopper into the drug storage bottle to deliver the drug.

[0011] Preferably, the limiting mechanism includes a sliding rod, a first limiting plate, a limiting fixing plate, and a second spring. The sliding rod is slidably mounted on the limiting cylinder, the first limiting plate is mounted on one end of the sliding rod, and the limiting fixing plate is mounted on the other end of the sliding rod. The second spring connects the outer wall of the limiting cylinder to the first limiting plate. The elasticity of the second spring pushes the sliding rod to slide on the limiting cylinder, thereby limiting and fixing the medicine bottle through the limiting fixing plate, improving the stability of the medicine bottle during use and preventing the medicine from shaking and falling off.

[0012] Preferably, the pressure relief mechanism includes a pressure relief cylinder, a guide slide rod, a second limiting plate, a sealing plug, a third spring, and a pressure relief hole. The medicine storage bottle has a pressure relief port. The pressure relief cylinder is installed at the pressure relief port of the medicine storage bottle. The guide slide rod is installed on the inner wall of the medicine storage bottle. The second limiting plate is installed on the guide slide rod. The sealing plug is slidably installed on the guide slide rod. The third spring connects the sealing plug and the second limiting plate. The pressure relief hole is installed on the upper part of the pressure relief cylinder. When the medicine in the medicine storage bottle is drawn into the syringe, a negative pressure is formed inside the medicine storage bottle. This pressure difference pushes the sealing plug to slide on the guide slide rod, thereby connecting the pressure relief port and the pressure relief hole, thus balancing the air pressure. Then, the elasticity of the third spring pushes the sealing plug to seal the pressure relief port and the pressure relief hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the drug injection mechanism extracts and injects the drug into the mouth of the livestock; the rebound mechanism assists the drug injection mechanism in rebounding, reducing the workload of the operator and improving convenience; the quantitative adjustment mechanism facilitates the quantitative injection of the drug, and the quantitative adjustment mechanism can adjust the amount of drug injected, improving practicality; the drug addition mechanism facilitates the placement and replacement of the drug; the limiting mechanism facilitates the limiting and fixing of the drug addition mechanism, improving the stability of the drug addition mechanism; and the pressure relief mechanism relieves the pressure inside the drug addition mechanism, allowing the drug inside the drug addition mechanism to flow smoothly into the drug injection mechanism.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0023] Example 1

[0024] like Figure 2 , Figure 4 and Figure 5 As shown, a livestock quantitative medication device includes a medication dispensing mechanism 01, a rebound mechanism 02, a quantitative adjustment mechanism 03, a medication dispensing mechanism 04, a limiting mechanism 05, and a pressure relief mechanism 06. The rebound mechanism 02 is installed on the medication dispensing mechanism 01, the quantitative adjustment mechanism 03 is installed on the rebound mechanism 02, the medication dispensing mechanism 04 is installed on the medication dispensing mechanism 01, the limiting mechanism 05 is installed on the medication dispensing mechanism 04, and the pressure relief mechanism 06 is installed on the medication dispensing mechanism 04.

[0025] The drug dispensing mechanism 01 extracts and dispenses the drug into the mouth of the livestock. The rebound mechanism 02 assists the drug dispensing mechanism 01 in rebounding. The quantitative adjustment mechanism 03 facilitates the quantitative dispensing of the drug. The drug addition mechanism 04 facilitates the placement and replacement of the drug. The limiting mechanism 05 facilitates the limiting and fixing of the drug addition mechanism 04. The pressure relief mechanism 06 performs pressure relief treatment inside the drug addition mechanism 04.

[0026] The drug delivery mechanism 01 includes a syringe 11, a piston 12, a pull rod 13, a push plate 14, a hook plate 15, and a drug delivery tube 16. The outer wall of the syringe 11 is provided with a scale. The piston 12 is slidably installed inside the syringe 11. The pull rod 13 is rotatably installed on the piston 12. The push plate 14 is installed on the outer end of the pull rod 13. The hook plate 15 is installed on the outer wall of the syringe 11. The drug delivery tube 16 is installed on the syringe 11. A first one-way valve is provided inside the drug delivery tube 16. The drug delivery mechanism 04 is installed on the syringe 11. A second one-way valve is provided inside the drug delivery mechanism 04.

[0027] The rebound mechanism 02 includes a first auxiliary ring 21, a second auxiliary ring 22 and a rebound spring 23. The first auxiliary ring 21 contacts the hook plate 15, the second auxiliary ring 22 contacts the push plate 14, and the rebound spring 23 connects the first auxiliary ring 21 and the second auxiliary ring 22. The rebound spring 23 is fitted on the outside of the pull rod 13.

[0028] The quantitative adjustment mechanism 03 includes an adjustment thread 31 and a threaded T-shaped cylinder 32. The adjustment thread 31 is provided on the pull rod 13, and the threaded T-shaped cylinder 32 is slidably installed in the syringe 11. The threaded T-shaped cylinder 32 is threadedly engaged with the adjustment thread 31 on the pull rod 13.

[0029] When medication is to be drawn, the elasticity of the return spring 23 pushes the push plate 14, causing the push plate 14 to move relative to the hook plate 15. This, in turn, drives the pull rod 13 to pull the piston 12 to slide away from the drug delivery tube 16 inside the syringe 11 until the threaded T-shaped cylinder 32 contacts and is limited by the hook plate 15. At this time, the first one-way valve inside the drug delivery tube 16 closes, and the second one-way valve inside the drug-passing needle 42 opens, allowing the medication in the storage bottle 43 to enter the syringe 11. Then, the push plate 14 is pushed, causing the pull rod 13 to push the piston 12 to slide closer to the drug delivery tube 16 inside the syringe 11. The first one-way valve in syringe 16 opens, and the second one-way valve in syringe 42 closes, thereby injecting the medicine in syringe 11 into the animal's mouth through syringe tube 16, thus achieving quantitative drug administration. When adjusting the amount of medicine administered, the first auxiliary ring 21 is pulled first, causing the return spring 23 to contract. The first auxiliary ring 21 moves away from the hook plate 15, at which point one end of the threaded T-shaped cylinder 32 is exposed. By rotating one end of the threaded T-shaped cylinder 32, the pull rod 13 moves relative to the threaded T-shaped cylinder 32 due to the thread relationship, thereby adjusting the position of piston 12, thus completing the adjustment of the quantitative drug administration amount.

[0030] Example 2

[0031] like Figures 3 to 7As shown, a livestock quantitative medication device includes a medication dispensing mechanism 01, a rebound mechanism 02, a quantitative adjustment mechanism 03, a medication dispensing mechanism 04, a limiting mechanism 05, and a pressure relief mechanism 06. The rebound mechanism 02 is installed on the medication dispensing mechanism 01, the quantitative adjustment mechanism 03 is installed on the rebound mechanism 02, the medication dispensing mechanism 04 is installed on the medication dispensing mechanism 01, the limiting mechanism 05 is installed on the medication dispensing mechanism 04, and the pressure relief mechanism 06 is installed on the medication dispensing mechanism 04.

[0032] The drug dispensing mechanism 01 extracts and dispenses the drug into the mouth of the livestock. The rebound mechanism 02 assists the drug dispensing mechanism 01 in rebounding. The quantitative adjustment mechanism 03 facilitates the quantitative dispensing of the drug. The drug addition mechanism 04 facilitates the placement and replacement of the drug. The limiting mechanism 05 facilitates the limiting and fixing of the drug addition mechanism 04. The pressure relief mechanism 06 performs pressure relief treatment inside the drug addition mechanism 04.

[0033] The drug delivery mechanism 01 includes a syringe 11, a piston 12, a pull rod 13, a push plate 14, a hook plate 15, and a drug delivery tube 16. The outer wall of the syringe 11 is provided with a scale. The piston 12 is slidably installed inside the syringe 11. The pull rod 13 is rotatably installed on the piston 12. The push plate 14 is installed on the outer end of the pull rod 13. The hook plate 15 is installed on the outer wall of the syringe 11. The drug delivery tube 16 is installed on the syringe 11. A first one-way valve is provided inside the drug delivery tube 16. The drug delivery mechanism 04 is installed on the syringe 11. A second one-way valve is provided inside the drug delivery mechanism 04.

[0034] The limiting mechanism 05 includes a sliding rod 51, a first limiting plate 52, a limiting fixing plate 53, and a second spring 54. The sliding rod 51 is slidably mounted on the limiting cylinder 41. The first limiting plate 52 is mounted on one end of the sliding rod 51, and the limiting fixing plate 53 is mounted on the other end of the sliding rod 51. The second spring 54 connects the outer wall of the limiting cylinder 41 with the first limiting plate 52.

[0035] The pressure relief mechanism 06 includes a pressure relief cylinder 61, a guide slide rod 62, a second limiting plate 63, a sealing plug 64, a third spring 65, and a pressure relief hole 66. The medicine storage bottle 43 is provided with a pressure relief port. The pressure relief cylinder 61 is installed at the pressure relief port of the medicine storage bottle 43. The guide slide rod 62 is installed on the inner wall of the medicine storage bottle 43. The second limiting plate 63 is installed on the guide slide rod 62. The sealing plug 64 is slidably installed on the guide slide rod 62. The third spring 65 connects the sealing plug 64 and the second limiting plate 63. The pressure relief hole 66 is installed on the pressure relief cylinder 61.

[0036] First, the medication is added to the storage bottle 43. When installing the storage bottle 43, the needle 42 is inserted through the rubber stopper 44 into the storage bottle 43 to deliver the medication. The second spring 54 pushes the sliding rod 51 to slide on the limiting cylinder 41, and then the limiting fixing plate 53 limits and fixes the storage bottle 43, improving the stability of the storage bottle 43 during use and preventing the medication from shaking and falling off. When the medication in the storage bottle 43 is drawn into the syringe 11, a negative pressure is formed in the storage bottle 43. The pressure difference pushes the sealing plug 64 to slide on the guide rod 62, thereby connecting the pressure relief port and the pressure relief hole 66 to balance the air pressure. Then, the third spring 65 pushes the sealing plug 64 to seal the pressure relief port and the pressure relief hole 66.

[0037] like Figures 1 to 7 As shown, this utility model discloses a livestock quantitative medication device. During operation, when medication needs to be drawn, the elastic spring 23 pushes the push plate 14, causing the push plate 14 to move relative to the hook plate 15. This, in turn, drives the pull rod 13 to pull the piston 12 within the syringe 11, sliding it away from the medication tube 16 until the threaded T-shaped cylinder 32 contacts and is limited by the hook plate 15. At this point, the first one-way valve in the medication tube 16 closes, and the second one-way valve in the medication needle 42 opens, allowing the medication in the storage bottle 43 to be drawn. The medication is inserted into the syringe 11, and then the push plate 14 is pushed, causing the pull rod 13 to push the piston 12 to slide towards the administration tube 16 within the syringe 11. At this time, the first one-way valve in the administration tube 16 opens, and the second one-way valve in the needle tip 42 closes, thereby administering the medication from the syringe 11 into the animal's mouth through the administration tube 16, thus achieving quantitative medication administration. When adjusting the amount of medication administered, the first auxiliary ring 21 is first pulled, causing the return spring 23 to contract, and the first auxiliary ring 21 moves away from the hook plate 15. At this point, one end of the threaded T-shaped cylinder 32 is exposed. By rotating one end of the threaded T-shaped cylinder 32, the threaded connection causes the pull rod 13 to move relative to the threaded T-shaped cylinder 32, thereby adjusting the position of the piston 12 and thus adjusting the amount of medication dispensed. First, the medication is added into the storage bottle 43. When installing the storage bottle 43, the medication needle 42 is inserted into the storage bottle 43 through the rubber stopper 44 to deliver the medication. The elasticity of the second spring 54 pushes the sliding rod 51 to the limit position. The syringe slides on the cylinder 41, thereby limiting and fixing the medicine bottle 43 through the limiting and fixing plate 53, improving the stability of the medicine bottle 43 during use and preventing the medicine from shaking and falling off. When the medicine in the medicine bottle 43 is drawn into the syringe 11, a negative pressure is formed in the medicine bottle 43. The pressure difference then pushes the sealing plug 64 to slide on the guide slide rod 62, thereby connecting the pressure relief port and the pressure relief hole 66, thus balancing the air pressure. Then, the elasticity of the third spring 65 pushes the sealing plug 64 to seal the pressure relief port and the pressure relief hole 66.

[0038] The main function achieved by this utility model is to facilitate automatic quantitative administration of medicine during the process of administering medicine to livestock, and to facilitate the adjustment of the amount of medicine administered, thereby improving practicality and convenience.

[0039] The above description is only a preferred embodiment of the present utility model.
