Description

Technical Field

[0001] The invention relates to the field of veterinary instruments, in particular to a medicine dispensing device for animal husbandry and veterinary medicine. Background Art

[0002] In veterinary clinical treatment, vials are often used to contain various drugs. Many drugs exist in powder form in vials. The reason is that this storage method helps to maintain the stability of the drugs, extend the shelf life, and facilitate storage and transportation. In the actual treatment of animal diseases, veterinarians often need to mix the drugs in the vials with specific liquid medicines. The reason is that the powder can be mixed with an appropriate amount of liquid medicine to dilute the drugs to an appropriate concentration and accurately prepare the precise dose required by factors such as the animal's weight and the severity of the disease. In addition, some drugs may have poor solubility or strong irritation when they exist alone. Mixing with suitable liquid medicines can improve the solubility of the drugs and reduce their irritation to the animal body, thereby improving the effectiveness and safety of the drugs, ensuring that the disease can be effectively fought and the adverse effects on the animal's body can be minimized during the treatment process.

[0003] Currently, there are two main ways for veterinarians to mix drugs in vials with liquid medicines. The first way is to use a syringe to directly add the liquid medicine into the vial and mix it with the powder medicine. However, due to the limited capacity of the syringe, when a larger dose of medicine needs to be prepared, it is necessary to extract and inject the liquid medicine multiple times. This is not only cumbersome, time-consuming and labor-intensive, but also increases the probability of errors during the operation, making it difficult to ensure the uniformity and accuracy of drug mixing.

[0004] The second method is to place the drug liquid and drug powder into a sealed container at the same time and mix them, and then use a reflux device to return the drug liquid to the vial. This method solves some of the problems caused by repeated operation of the syringe in the first method to a certain extent and improves the efficiency of drug dispensing. However, the drug powder that is compacted in the vial is difficult to fully contact and mix evenly with the drug liquid in the sealed container. During the reflux process, the incompletely mixed compacted powder may block the pipe of the reflux device or cannot be completely refluxed into the vial, resulting in inaccurate drug dosage and affecting the treatment effect.

[0005] Based on the above viewpoints, the present invention provides a medicine dispensing device for animal husbandry and veterinary medicine. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a dispensing device for animal husbandry and veterinary medicine, which breaks up the powder compacted inside the vial through a rotating wound elastic cleaning sheet, and the unfolded wound elastic cleaning sheet quickly sweeps away the powder compacted in the vial, thereby quickly cleaning the vial, preventing the powder from being compacted and unable to mix with the medicine solution, thereby improving the dispensing and mixing efficiency.

[0016] The rotating wound elastic cleaning sheet is used to break up the powder compacted inside the vial, causing the powder to fall on the top of the guide sleeve until the top of the cleaning component reaches the top of the vial. At this time, the spring cone is pressed back by the top of the vial, and the unfolded wound elastic cleaning sheet will quickly sweep away the powder compacted on the top of the vial, thereby quickly cleaning the vial to prevent the compaction of the powder from making it unable to mix with the medicine solution, thereby improving the dispensing and mixing efficiency.

[0017] As the vibration slider continues to rise and fall, it will continuously drive the vibration plate to rise and fall, and the vibration bumps will hit the bottom of the internal partition of the agitator shell, thereby causing large pieces of powder that have fallen on the bottom of the agitator shell to move upward, preventing them from accumulating at the bottom of the agitator shell and being unable to be driven for stirring, thereby fully improving the stirring efficiency.

[0018] The piston disc rises and falls rapidly, and the piston tube will continue to rise and fall inside the exhaust pipe, thereby discharging the gas in the chamber above the agitator shell, preventing air from mixing into the syringe and causing part of the gas and the mixed medicine to be injected into the livestock. Medical staff do not need to vent the syringe before injection, and also avoid contaminating the needle in the complex environment of the livestock farm during the venting process. When the gas inside the chamber above the agitator shell is exhausted, the connecting piece will move downward under the action of the atmosphere, and medical staff can judge whether the air in the agitator shell is exhausted by observing the syringe fixed by the dust-proof elastic pad.

The elastic dust cover 23 is deformed and clamped on the outer side of the protective mounting frame 3, thereby fixing the syringe bottle and forming a seal for the syringe bottle.

[0023] like Figure 5 , Figure 6 and Figure 7 As shown, the cleaning assembly 17 includes a cleaning rod 171, and the top and near the bottom of the cleaning rod 171 are provided with a wound elastic cleaning sheet 172 wound on the outer wall of the cleaning rod 171, and the wound elastic cleaning sheet 172 is made of elastic material.

[0025] Embodiment 2: Figure 8 and Fig. 9 As shown, this embodiment provides another technical solution based on the first embodiment. The vibration-driven end 7 includes a liquid storage shell 72. A piston-type reciprocating electric cylinder 71 is installed at the outer end of the liquid storage shell 72. Branch pipes are provided at the top and bottom of the middle position of the liquid storage shell 72. An extrusion hammer 73 is slidingly connected in the two branch pipes. The extrusion hammer 73 is composed of two columns with different diameters. The diameter of the lower half of the extrusion hammer 73 is larger than the diameter of the upper half. The branch pipe in the middle and upper part of the liquid storage shell 72 is connected to a hose connected to the other port of the two-way pump 16. The inner end of the liquid storage shell 72 is also fixedly connected to a vertical pipe. The bottom and top of the vertical pipe are slidingly connected to a shock slider 74.

[0026] like Figure 4As shown, a vibration disk assembly 10 is arranged below the partition of the agitator housing 1, and the vibration disk assembly 10 includes a vibration disk body 101, and the inner side wall of the vibration disk body 101 is fixedly connected with a plurality of vibration disk blocks 102 distributed in a circular array through springs, and the other end of the vibration disk block 102 is clamped on the outer side wall of the drive shaft 111, and the upper side wall of the vibration disk body 101 is densely covered with a plurality of shock protrusions 103, and the vibration disk body 101 is arranged between the middle partition of the agitator housing 1 and the shock slider 74 on the upper side, and a spring is further arranged between the vibration disk body 101 and the partition of the agitator housing 1, when the two shock sliders 74 are respectively abutted against the piston assembly 9 and the vibration disk assembly 10, the piston reciprocating electric cylinder 71 is started, driving the piston rod connected to its movable end to pull quickly, thereby driving the two shock sliders 74 to move up and down, and at this time, the rotating shaft assembly 11 is still in a rotating state, so the vibration disk body 101 is in Under the action of centrifugal force, the vibration plate block 102 is completely retracted into the vibration plate body 101 and is no longer stuck in the drive shaft 111. The vibration plate assembly 10 as a whole is in a disengaged state from the rotating shaft assembly 11, and the bottom rod assembly 12 rotates under the drive of the rotating shaft assembly 11. The tail rod limit block 122 extends into the piston slot 92 and is fixed to the piston plate 91, so that the piston assembly 9 as a whole no longer moves up and down compared with the bottom rod assembly 12. At this time, the extended shock slider 74 cannot drive the piston assembly 9 to descend, and instead pushes more water flow to drive the upper shock slider 74 to move upward. In the process of continuous lifting of the shock slider 74, it will continuously drive the vibration plate body 101 to rise and fall, and hit the bottom of the internal partition of the agitator housing 1 through the shock protrusion 103, so that the large pieces of powder that fall on the bottom of the agitator housing 1 move upward to avoid accumulation at the bottom of the agitator housing 1 and unable to be driven for stirring, thereby fully improving the stirring efficiency.

[0027] Embodiment 3: Figure 4 , Figure 8 and Fig.10As shown, this embodiment provides another technical solution based on the first and second embodiments, the bottom of the driving shaft 111 is fixedly connected with a bottom rod assembly 12, the bottom rod assembly 12 includes a bottom tail rod 121, and the outer wall of the bottom tail rod 121 is fixedly connected with a plurality of tail rod limit blocks 122 distributed in a circumferential array through a spring, and the outer wall of the bottom tail rod 121 is also sleeved with a piston assembly 9, the piston assembly 9 includes a piston disk 91, and the inner wall of the piston disk 91 is provided with a piston groove 92 used in conjunction with the tail rod limit block 122, the piston groove 92 is annular, and the bottom of the outer wall of the bottom tail rod 121 is sleeved with a piston for supporting the piston disk 91, a piston tube 93 is fixedly connected to the outer wall of the piston disk 91, a one-way valve 94 is also installed inside the piston tube 93, an upper side wall of the agitator housing 1 is connected with an exhaust pipe 4, the piston tube 93 is limitedly slidably connected inside the exhaust pipe 4, a liquid filling port 6 is connected to the upper position of the outer side wall of the agitator housing 1, a liquid taking port 5 is also provided on the upper side wall of the agitator housing 1, a telescopic material extraction component 18 is fixedly connected inside the liquid taking port 5, the telescopic material extraction component 18 includes a material extraction pipe 181, a connecting piece 182 is fixedly connected to the upper end face of the lower side wall of the material extraction pipe 181, and a dust-proof spring is fixedly connected to the upper end face of the connecting piece 182 When the liquid medicine is fully stirred, the medical staff inserts the needle tube into the dustproof elastic pad 183, and the needle head squeezes the dustproof elastic pad 183, so that the needle tube is fixed and the surrounding of the needle head is sealed. At this time, the shaft assembly 11 stops rotating, and the tail rod limit block 122 is retracted from the piston slot 92. The piston disc 91 can move up and down compared with the shaft assembly 11, and the vibration disc block 102 is inserted into the shaft assembly 11, so that the vibration disc body 101 cannot move up and down. At this time, when the movable end of the piston reciprocating electric cylinder 71 is extended, it cannot squeeze the upper shock slider 74 to move upward, and instead drives more water flow to push the lower shock slider 74 moves downward, causing the piston disk 91 to rise and fall quickly, and the piston tube 93 will continue to rise and fall inside the exhaust pipe 4, thereby discharging the gas in the chamber above the agitator housing 1, avoiding air from mixing into the syringe and causing part of the gas and the mixed medicine to be injected into the livestock. Medical staff do not need to vent the syringe before injection, and also avoid contaminating the needle in the complex environment of the livestock farm during the venting process. When the gas inside the chamber above the agitator housing 1 is exhausted, the connecting piece 182 will move downward under the action of the atmosphere, and the medical staff can judge whether the air in the agitator housing 1 is exhausted by observing the syringe fixed by the dust-proof elastic pad 183.

[0028] Working principle: When it is necessary to dispense medicine, first pour the medicine liquid into the agitator housing 1 through the liquid filling port 6, and then use the end cover to seal the liquid filling port 6, then turn the vial filled with medicine powder upside down and insert the bottle mouth into the protective mounting frame 3, the elastic dust cover 23 with elasticity is deformed and clamped on the outside of the protective mounting frame 3, thereby fixing the vial and forming a seal for the vial, and then start the main drive motor 81, the output end of the main drive motor 81 drives the main drive gear cone 82 to rotate through the shaft rod, and then drives the main shaft gear cone 112 engaged with it to rotate rapidly, so that The entire rotating shaft assembly 11 rotates rapidly, and the driving tooth cone 22 at the top of the rotating shaft assembly 11 drives the bottom tooth cone 19 to rotate through the connecting tooth cone 21, thereby driving the water storage jacket 15 to rotate rapidly, and the cleaning assembly 17 inside the water storage jacket 15 will rotate at high speed along with the water storage jacket 15. When the cleaning assembly 17 rotates at high speed, the winding elastic cleaning sheet 172 located at the top of the cleaning assembly 17 unfolds, thereby crushing the powder agglomerates falling on the top of the guide sleeve 14, and the powder falls into the centrifugal spreading head 1 through the through hole at the top of the water storage jacket 15. 14, and thrown into the inside of the agitator housing 1 through the spreading groove inside the centrifugal spreading head 114. Since the centrifugal spreading head 114 is in a high-speed rotating state, when the powder is thrown, the unbroken powder agglomerates are thrown farther because of their larger mass and greater inertia, and they will fall on the outside of the agitator housing 1, while the lighter powder is thrown closer to the main stirring rod 113. When the centrifugal spreading head 114 rotates, it will drive the auxiliary stirring assembly 1 through the main gear 115. 3 rotates in the opposite direction to the rotating shaft assembly 11, and the powder agglomerates with larger mass are thrown closer to the rotating shaft assembly 11. Therefore, the auxiliary stirring assembly 13 rotating in the opposite direction can exert a force opposite to the rotating shaft assembly 11 on these larger agglomerates, which helps to break up these agglomerated powders, while the normal powders closer to the rotating shaft assembly 11 will be quickly stirred by the rotating shaft assembly 11, and the stirring efficiency is improved by the partition stirring method, so that they form a cross-flow state in the stirring container, thereby promoting uniform mixing of the entire powder system.

[0029] When part of the powder is compacted inside the vial, the two-way pump 16 is started to slowly pump the water at the top of the fork in the middle of the liquid storage shell 72 into the water storage sleeve 15, thereby driving the entire cleaning assembly 17 to start moving upward, and the top of the cleaning assembly 17 penetrates into the vial. The spring cone 173 provided on the top of the cleaning assembly 17 can break the blocked powder, allowing the cleaning assembly 17 to smoothly enter the vial, and the rotating winding elastic cleaning sheet 172 will break the powder compacted inside the vial, causing the powder to fall on the guide sleeve 14. At this time, the spring cone 173 is pressed back by the top of the vial, and the unfolded winding elastic cleaning sheet 172 will quickly sweep away the powder compacted on the top of the vial, thereby quickly cleaning the vial. At the same time, the winding elastic cleaning sheet 172 located under the cleaning rod 171 leaves the water storage sleeve 15, so it will be unfolded under the drive of high-speed rotation, and the powder that falls on the top of the water storage sleeve 15 will be crushed, so that the powder can smoothly enter the centrifugal spreading head 114.

[0030] When the two-way pump 16 sucks water at the top of the middle branch pipe of the liquid storage shell 72, the extrusion hammer 73 will be driven to move upward, and the lower part of the extrusion hammer 73 will slowly enter the liquid storage shell 72, thereby squeezing the two shock sliders 74 to expand outward until the top of the cleaning assembly 17 is at the top position of the syringe bottle. At this time, the two shock sliders 74 are respectively in contact with the piston assembly 9 and the vibration disk assembly 10.

[0031] When the two shock sliders 74 are respectively in contact with the piston assembly 9 and the vibration disk assembly 10, the piston reciprocating electric cylinder 71 is started, driving the piston rod connected to its movable end to twitch quickly, thereby driving the two shock sliders 74 to move up and down, and at this time the shaft assembly 11 is still in a rotating state, so the vibration disk block 102 in the vibration disk body 101 is retracted into the vibration disk body 101 under the action of centrifugal force and is no longer stuck in the drive shaft 111, the vibration disk assembly 10 is in a disengaged state from the shaft assembly 11 as a whole, and the bottom rod assembly 12 rotates under the drive of the shaft assembly 11, and the tail rod limit block 122 extends into the piston The inside of the slot 92 is then fixed to the piston disc 91, so that the piston assembly 9 as a whole no longer moves up and down compared to the bottom rod assembly 12. At this time, the extended shock slider 74 cannot drive the piston assembly 9 to descend, and instead pushes more water flow to drive the upper shock slider 74 to move upward. In the process of continuous lifting and lowering of the shock slider 74, it will continuously drive the vibration disc body 101 to rise and fall, and hit the bottom of the internal partition of the agitator housing 1 through the shock protrusion 103, thereby causing the large pieces of powder that fall on the bottom of the agitator housing 1 to move upward, avoiding its accumulation at the bottom of the agitator housing 1 and being unable to be driven for stirring, thereby fully improving the stirring efficiency.

[0032] It should be noted that the large pieces of powder that are impacted and lifted are mostly powder that is compacted inside the vial. Since the winding elastic cleaning sheet 172 located below handles a large amount of this type of powder in a short period of time, the partition mixing method may not be able to repeatedly disperse the agglomerated powder. This method can effectively avoid powder accumulation. At the same time, the active end of the piston reciprocating electric cylinder 71 is at the middle value of its piston reciprocating electric cylinder 71 limit stroke. In the process of driving the shock slider 74 to move, the piston reciprocating electric cylinder 71 always moves between the middle value and the maximum value. When the two shock sliders 74 need to be reset, it is only necessary to completely reset the active end of the piston reciprocating electric cylinder 71 so that the two shock sliders 74 both come to the innermost side of the fork tube at the inner end of the liquid storage shell 72. Then the active end of the piston reciprocating electric cylinder 71 comes to the middle position formed by it, and the two shock sliders 74 can be reset.

[0033] When the liquid medicine is fully stirred, the medical staff inserts the needle tube into the dustproof elastic pad 183, and the needle head squeezes the dustproof elastic pad 183, so that the needle tube is fixed and the surrounding of the needle head is sealed. At this time, the rotating shaft assembly 11 stops rotating, and the tail rod limit block 122 is retracted from the piston slot 92. The piston disc 91 can move up and down compared with the rotating shaft assembly 11, and the vibration disc block 102 is inserted into the rotating shaft assembly 11, so that the vibration disc body 101 cannot move up and down. At this time, when the movable end of the piston reciprocating electric cylinder 71 is extended, it cannot squeeze the upper shock slider 74 to move upward, and instead drives more water flow to push the lower shock slider 74 to move upward. The piston plate 91 moves downward, causing the piston plate 91 to rise and fall quickly, and the piston tube 93 will continue to rise and fall inside the exhaust pipe 4, thereby discharging the gas in the chamber above the agitator housing 1, avoiding air from mixing into the syringe and causing part of the gas and the mixed liquid medicine to be injected into the livestock. Medical staff do not need to vent the syringe before injection, and also avoid contaminating the needle in the complex environment of the livestock farm during the venting process. When the gas inside the chamber above the agitator housing 1 is exhausted, the connecting piece 182 will move downward under the action of the atmosphere, and the medical staff can judge whether the air in the agitator housing 1 is exhausted by observing the syringe fixed by the dust-proof elastic pad 183.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
