Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of eye drop devices, specifically a kind of veterinary liquid eye drop device, belong to the technical field of livestock breeding. BACKGROUND

[0002] In veterinary clinic and farm, liquid eye drop is the common operation for treating eye diseases or carrying out vaccination. At present, the common veterinary liquid eye drop device on the market mostly adopts simple drop bottle or dropper structure, and its basic operation mode is to rely on the user to manually squeeze the bottle body, so that the liquid medicine is dropped from the drop nozzle under the action of pressure. However, this traditional method has many inherent defects: first, since the intensity of manual squeezing is difficult to accurately control, it is easy to cause excessive liquid medicine drop, which not only causes waste of medicine and increases breeding cost, but also may pollute the animal's face and surrounding environment due to liquid medicine flowing out; second, animals are easy to swing their heads during eye drop due to nervousness or discomfort, and the existing devices generally lack effective stable positioning function, so that the liquid medicine is difficult to accurately drop into the target eye area, the operation accuracy is insufficient, and even the cornea may be touched by mistake, causing discomfort or eye injury of the animal.

[0003] In order to overcome the above problems, some tentative improvement schemes appear on the market. For example, the simple animal eye medicine applicator disclosed in the announcement No. CN215130810U reduces the stimulation to the animal's eye by using an extension pipe made of latex material, and tries to send the liquid medicine more directly to the bottom of the eyelid. However, this device still does not solve the core problem of inaccurate liquid medicine dosage control, and the amount of drug delivery still depends on the user's hand feeling, which cannot guarantee the accuracy and consistency of the dosage each time; for example, the adjustable eye drop device disclosed in the announcement No. CN221904201U tries to control the moving distance of the pressing plate by setting a limiting rod, so as to control the deformation amount of the bottle body, so as to achieve the purpose of adjusting the dosage. This scheme has made a step forward in dosage control, but its structure is usually complex, and does not involve solving the problem of sedimentation or stratification of liquid medicine that may occur during storage. For suspension liquid or some liquid medicine that is easy to settle, even if the volume of each extrusion is accurate, if the liquid medicine itself is not uniform, it will also lead to inaccurate actual drug concentration, which seriously affects the treatment effect or immune effect. In addition, some complex electric eye drop devices are difficult to popularize and apply in veterinary clinics or farms due to high cost and inconvenient operation. UTILITY MODEL CONTENTS

By arranging the adjusting rotating rod 23 in the pressing outer rod 21, and threadedly connecting the threaded ring on the rod of the adjusting rotating rod 23 with the threaded cavity 211 formed in the rod of the pressing inner rod 24, when the adjusting rotating rod 23 is rotated, the scale line 213 can be used to accurately control the extension length of the pressing inner rod 24 relative to the pressing outer rod 21, so as to determine the total downward stroke of the pressing inner rod 24, the push rod 25 and the liquid pushing piston 26 fixedly connected to the bottom end of the pressing inner rod 24 during pressing operation. That is, the user can preset different pressing strokes by simple rotating operation during use, and then correspondingly push different volumes of the liquid pushing piston 26, so as to accurately and quantitatively control different volumes of liquid medicine.

[0043] Further, the rod of the adjusting rotating rod 23 and the pressing outer rod 21 are further connected with a damping bearing 28, the upper end of the pressing outer rod 21 is fixedly connected with a pressing head 22, the upper end of the adjusting rotating rod 23 is fixedly connected with an internal hexagonal screw head 212, the pressing head 22 is formed with an inner groove 29, the internal hexagonal screw head 212 is movably embedded in the bottom surface of the inner groove 29, a blocking block 210 is movably clamped in the inner groove 29, the damping bearing 28 provides appropriate resistance for the rotating operation of the adjusting rotating rod 23, prevents self-rotation displacement due to vibration or accidental touch when no human operation is performed, and guarantees the stability of the preset pressing stroke and quantitative value.

When the pressing assembly 2 is reset and the liquid pushing piston 26 moves upward, a negative pressure is formed in the liquid storage cylinder 31, and the liquid pressure in the medicine storage tube 1 acts on the liquid inlet block 36 to overcome the elastic force of the liquid inlet spring 38, drive the liquid inlet piston 34 to separate from the liquid inlet hole position 33, open the channel and make the liquid enter the liquid storage cylinder 31.

[0047] As shown in Figure 1 , Figure 2 , Figure 5 and Figure 8 , the mixing assembly 4 is provided with a mixing rotating rod 41, the two ends of the mixing rotating rod 41 are respectively rotatably connected to the inner walls of the upper and lower ends of the liquid storage tube 1, the rod body of the mixing rotating rod 41 is coaxially fixedly connected with a ball screw 42, and the abutting part of the ball screw 42 and the rod body of the mixing rotating rod 41 is in a stepped surface shape.

[0048] As shown in Figure 1 , Figure 2 and Figure 10As shown, the upper end of the droplet pipe 6 is communicated with a docking pipe 61, the docking pipe 61 is docked with the liquid outlet seat 5, and the inner wall of the docking pipe 61 is provided with a friction surface 62, and the bottom end of the droplet pipe 6 is provided with an arc-shaped droplet outlet 63, so that the upper end of the droplet pipe 6 is docked with the liquid outlet seat 5 through the docking pipe 61, which facilitates disassembly, cleaning or replacement of the droplet pipe 6, while the friction surface 62 ensures the tightness of the connection to prevent leakage of the liquid medicine from the interface, and the arc-shaped droplet outlet 63 can better fit the physiological profile of the animal's eyelid, which can reduce the shock and irritation to the animal during eye dropping operation, and can more accurately drop the liquid medicine into the target eye area at a closer distance, effectively avoiding the liquid medicine flowing to the face or accidentally touching the cornea, and improving the accuracy of eye dropping operation.

[0049] Working principle: Before use, fill the medicine into the storage pipe 1 through the liquid injection port 11, and accurately adjust the stroke of the pressing assembly 2 by rotating the adjusting rotating rod 23, the adjusting rotating rod 23 is engaged with the threaded cavity 211 in the pressing inner rod 24 through the threads on the shaft of the adjusting rotating rod 23, the length of the pressing inner rod 24, the push rod 25 fixedly connected with the pressing inner rod 24 and the push liquid piston 26 relative to the pressing outer rod 21 is changed by rotating, which corresponds to the maximum downward stroke of the push liquid piston 26 in the liquid storage cylinder 31, thereby presetting the single push liquid volume to realize quantitative control, after adjustment, the damping bearing 28 can prevent the adjusting rotating rod 23 from being accidentally rotated, and the blocking block 210 can be placed in the inner recess 29 to cover the inner hexagonal head 212 to avoid accidental touch;

[0050] When eye dropping operation is needed for livestock, the arc-shaped droplet outlet 63 at the bottom end of the droplet pipe 6 is close to the animal's eye, the pressing head 22 is pressed downward, the pressing outer rod 21 is inserted into the movable groove 14 at the bottom end to provide guidance, and the pressing inner rod 24, the push rod 25 and the push liquid piston 26 are driven to move downward together, the push liquid piston 26 compresses the return spring 32 and pushes the pre-filled quantitative liquid medicine in the liquid storage cylinder 31 to generate pressure, which first acts on the liquid outlet piston 52 to overcome the resistance of the liquid outlet spring 53 to open it, and the liquid medicine immediately flows into the liquid outlet channel of the liquid outlet seat 5, if the pressing force is too large to cause the instantaneous flow of the liquid medicine to be too large, the excess liquid medicine can be temporarily stored in the buffer cavity 54 and the elastic diaphragm 55 is deformed to play a buffering role, then the liquid medicine is smoothly squeezed out under the elastic recovery of the elastic diaphragm 55, ensuring that it naturally falls from the arc-shaped droplet outlet 63 in the form of droplets rather than high-speed injection, thereby safely and accurately dropping into the animal's eye;

[0051] When the inner pressing rod 24 is pressed down, the connecting rod 44 fixedly connected thereto drives the screw nut 43 to move down, and since the screw nut 43 is threadedly sleeved on the ball screw 42 fixed to the mixing rotating rod 41, the linear motion is converted into the rotating motion of the ball screw 42 and the mixing rotating rod 41, thereby driving the plurality of mixing blades 45 connected to the lower rod body of the mixing rotating rod 41 to rotate, so as to stir the liquid medicine in the medicine storage tube 1, prevent the medicine from precipitating, and ensure the uniform concentration of the liquid medicine to be dripped subsequently.

[0052] When the pressing head 22 is released, the compressed reset spring 32 releases energy, pushes the liquid pushing piston 26, the push rod 25 and the inner pressing rod 24 to reset and move up as a whole, at this time, the negative pressure is formed in the liquid storage cylinder 31, and the liquid medicine in the medicine storage tube 1 is gathered in the liquid collecting groove 13 guided by the bottom inclined surface 12 under the action of gravity, the liquid pressure acts on the liquid inlet block 36, overcomes the elastic force of the liquid inlet spring 38, pushes the liquid inlet piston 34 fixedly connected with the liquid inlet block 36 through the liquid inlet connecting rod 35 to be separated from the liquid inlet hole position 33, the liquid medicine can enter the liquid storage cylinder 31 from the liquid collecting groove 13 to complete the liquid supplementing, then the liquid inlet spring 38 pushes the liquid inlet block 36 and the liquid inlet piston 34 to reset and reseal the liquid inlet hole position 33 to prevent the liquid medicine from flowing back, and the liquid outlet piston 52 also resets and closes the liquid outlet channel under the action of the liquid outlet spring 53, the device returns to the standby state and is ready for the next precise and quantitative eye dropping operation.
