Description

Technical Field

[0001] The utility model relates to the technical field of medical injection dosing, in particular to a continuous injection pushing mechanism. Background Art

[0002] When treating animals with drugs, targeted medication is required. However, animals have large bodies and require large amounts of drugs. If a small injection mechanism is used, continuous addition of drugs and injections are required to complete the delivery of the entire drug. The traditional method is to mix and compound the drugs and then fill them into a basic drug delivery mechanism, such as a drip bottle, to continuously deliver the drugs to the animals. However, when the condition changes and flexible drug addition operations are required, the drip bottle needs to be taken out, re-compounded, and then continued to be injected. This is inconvenient to operate and increases pain. In addition, the improved drug pushing mechanism based on it has a spiral feeding mechanism added inside. The gap between the external thread and the internal thread will retain the drugs. Long-term residue will affect the cycle, and the drugs in the residual area will also affect the efficacy of the entire drug.

[0003] The existing injection and drug pushing mechanism cannot meet the needs of flexible drug addition or repeated operations. For example, a livestock and veterinary drug feeder with a protective structure disclosed in publication number CN216168076U uses a series of linkage mechanisms such as a ball valve, a piston and a threaded rod to suck the drug liquid from the drug tube into the syringe, and push the drug liquid inside the syringe to the end. In this process, gaps will be generated between the threads, and there will be residual drugs on the surface of the ball valve and the piston. The residual drugs will affect the efficacy of the new drugs, and the efficiency of quantitative pushing cannot be achieved, and the drug efficacy is prone to instability.

[0004] Therefore, it is necessary to invent a continuous injection propulsion mechanism to solve the above problems. Summary of the Invention

[0005] The utility model aims to provide a continuous injection pushing mechanism to solve the problems that the traditional Chinese medicine injection dosing mechanism cannot do quantitative dosing and needs to be completely disassembled when dosing.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a continuous injection pushing mechanism, comprising a basic medicine delivery mechanism and a medicine adding mechanism, the basic medicine delivery mechanism is filled with a basic medicine, and is transported to the surface of animal skin through a bottom rubber stopper and a connecting tube, the medicine adding mechanism comprises a spike head, the spike head penetrates into the bottom rubber belt of the basic medicine delivery mechanism, an inner medicine barrel is fixedly connected to the spike head, a slider is fixedly connected to the inner medicine barrel, the inner medicine barrel and the side ends of the slider are sleeved in a sleeve, the sleeve is nested in a rotating barrel, a strip groove is opened on the rotating barrel, one end of a spring is fixedly connected in the strip groove, and the other end of the spring contacts the surface of the slider.

[0007] Preferably, a handle is fixedly connected to the rotating barrel.

[0008] Preferably, the spike head is made of metal, and the cross-section of the end portion thereof extending into the inner portion of the basic medicine delivery mechanism is conical, and the diameter of the spike head is one tenth of the diameter of the inner medicine barrel.

[0009] Preferably, the inner medicine barrel is hollow and made of transparent material, is filled with functional medicine, and is connected to the spike head.

[0010] Preferably, an S-shaped groove is provided on the sleeve, and the width of the groove is adapted to the width of the slider. The slider can extend out of the groove and the height thereof is higher than the surface of the strip groove.

[0011] Preferably, the handle is made of resin material and can be integrally formed with the rotating barrel. The strip groove is provided in the middle of the rotating barrel, and the length of the strip groove is adapted to the length of the S-shaped groove provided on the sleeve.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The utility model sets a sleeve between the inner medicine barrel and the rotating barrel, and opens an S-shaped groove on the sleeve. The inner medicine barrel is pushed forward by limiting the movement of the slider in the S-shaped groove and the strip groove. The structure is simple and there is no waste of space due to too many mechanisms.

[0014] 2. The utility model connects the spring and the slider in the strip groove in the rotating barrel, so that the slider can be quickly pulled back to the initial position when it moves to the front end or the handle is not turned, saving the time of pulling the inner medicine barrel back to replenish medicine and improving the efficiency of dosing.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The utility model provides Figure 1-3 The continuous injection pushing mechanism shown includes a basic medicine delivery mechanism 1 and a medicine adding mechanism 2. The basic medicine delivery mechanism 1 is filled with a basic medicine, and the basic medicine is delivered to the surface of the animal skin through a bottom rubber stopper and a connecting tube. The medicine adding mechanism 2 includes a spike head 201, which penetrates into the bottom rubber belt of the basic medicine delivery mechanism 1. The spike head 201 is fixedly connected to an inner medicine barrel 202, and the inner medicine barrel 202 is fixedly connected to a slider 203. The side ends of the inner medicine barrel 202 and the slider 203 are sleeved in a sleeve 204, and the sleeve 204 is nested in a rotating barrel 205. A strip groove 206 is opened on the rotating barrel 205, and one end of a spring 207 is fixedly connected in the strip groove 206. The other end of the spring 207 contacts the surface of the slider 203, and a handle 210 is fixedly connected to the rotating barrel 205.

[0024] By utilizing the cooperation of the dosing mechanism 2 and the basic drug delivery mechanism 1, the functional agent is added to the basic agent without moving the fixed position of the animal skin. The dosing can be achieved and the dosing can be quantitative. The entire dosing process is easy and painless, and the efficacy of the quantitative dosing is more stable.

[0025] The spike head 201 is made of metal, and the cross-section of the inner end thereof extending into the basic medicine delivery mechanism 1 is conical, and the diameter of the spike head 201 is one tenth of the diameter of the inner medicine barrel 202. The inner medicine barrel 202 is hollow and made of transparent material. The inner medicine barrel 202 is filled with functional medicines, and the inner medicine barrel 202 is connected to the spike head 201. An S-shaped groove is provided on the sleeve 204, and the width of the groove is adapted to the width of the slider 203. The slider 203 can extend out of the groove and the height thereof extending out of the groove is higher than the surface of the strip groove 206.

[0026] Rotating the rotating barrel 205 can push the slider 203 toward the front end of the strip groove 206 to push the functional medicine into the basic medicine delivery mechanism 1.

[0027] The handle 210 is made of resin material and can be integrally formed with the rotating barrel 205 . The strip groove 206 is provided in the middle of the rotating barrel 205 . The length of the strip groove 206 matches the length of the S-shaped groove on the sleeve 204 .

[0028] The handle 210 is turned to drive the rotating barrel 205 to rotate, pushing the slider 203 forward. At the same time, the deformation of the spring 207 can instantly pull the slider 203 back to the initial position, and the inner medicine barrel 202 begins to be filled and dosing.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-3 When using the present invention, the drug solution is first delivered to the animal's skin through the basic drug delivery mechanism 1, the rubber stopper and the connecting tube. When it is necessary to push or add drugs to the basic drug delivery mechanism 1, the spike head 201 on the dosing mechanism 2 is used to pierce the rubber stopper of the basic drug delivery mechanism 1 to push or add drugs to the basic drug delivery mechanism 1.

[0031] Refer to the instruction manual Figure 3-5 When using the present invention, by continuously rotating the handle 210 clockwise or counterclockwise (in one direction), the rotating barrel 205 is driven to rotate, so that the slider 203 in the strip groove 206 continuously moves forward, driving the inner medicine barrel 202 forward, and transporting the liquid medicine in the inner medicine barrel 202 toward the spike head 201;

[0032] As the slider 203 continues to move forward, the spring 207 is continuously stretched. When the slider 203 reaches the bottom (the end of the strip groove 206) and the handle 210 is released, it is pulled back to the initial position by the spring 207, achieving rapid reset, saving time for filling and adding medicine in the inner medicine barrel 202 faster and more conveniently.
