Abstract
Description
Technical Field
[0001] This invention relates to the field of medical auxiliary products technology, specifically to an ophthalmic eye drop auxiliary dripping device and its usage method. Background Technology
[0002] Eye drops are one of the most commonly used drug formulations in ophthalmology, offering direct and rapid treatment for many eye conditions. With changing lifestyles and working conditions, people spend more and more time using their eyes, such as prolonged computer use, mobile phone use, television viewing, and video game playing, easily leading to visual fatigue and dry eye syndrome, thus requiring dry eye eye drops. Examples include sodium hyaluronate or polyethylene glycol eye drops. For infectious conjunctivitis or infectious inflammatory reactions, anti-infective eye drops may be needed; for example, for bacterial infections, levofloxacin eye drops may be required for antibacterial treatment. If itchy eyes are caused by allergies, anti-allergy eye drops, such as olopatadine eye drops, may be needed for relief. For immune-related diseases, such as phlyctenular conjunctivitis, steroid eye drops, such as fluorometholone eye drops, are required. For accurate refraction testing, pupil dilation may be necessary, requiring the use of mydriatic eye drops.
[0003] When going to an ophthalmologist for eye examinations and treatments, it's often necessary to use various eye drops over a long period. Theoretically, using eye drops is quite simple: just tilt your head back, open your eyes, and squeeze the bottle. However, some people still encounter several problems when actually using eye drops:
[0004] 1. When something gets close to your eye, you will involuntarily close your eyes. This is a normal defensive reaction of the body. Therefore, some people may blink frequently when they are not used to using eye drops, which may prevent the eye drops from being put into their eyes and make it more time-consuming and laborious.
[0005] 2. The amount of eye drops dispensed is difficult to control, depending on the material and thickness of the eye drop bottle, as well as the pressure applied by the user. Too much pressure results in a large volume being squeezed out, which is easily wasted. Too little pressure results in no drops being dispensed.
[0006] 3. Low accuracy when aiming the drops at the eye; when applying the drops, the head needs to be tilted back, the hand is not steady, the accuracy is low, and it is easy to drop outside the eye, requiring repeated application, which is very wasteful.
[0007] 4. After opening, the shelf life is generally one month, and at most three months. Once opened, the specific expiration date of the eye drops is unclear, which can easily lead to the eye drops expiring without being used, or even worsening of the patient's eye disease. Summary of the Invention
[0008] One of the objectives of this invention is to provide an auxiliary device for administering ophthalmic eye drops, in order to solve the above-mentioned problems.
[0009] To achieve the above objectives, an ophthalmic eye drop auxiliary dripping device is provided, comprising a housing and a controller. The upper surface of the housing is provided with a mounting groove for placing an inverted eye drop bottle. The inner wall of the mounting groove is provided with a squeezing component for squeezing the eye drop bottle. The outer side of the housing is provided with a squeezing adjustment wheel for driving the squeezing component to squeeze the eye drop bottle. The squeezing adjustment wheel is connected to a potentiometer.
[0010] Below the mounting slot is a dropper disposal tank, and the side wall of the dropper disposal tank is equipped with a laser emitter and a laser receiver; the eye droplets accumulated at the head of the eye drop bottle by squeezing are located on the path of the laser emitter and the laser receiver.
[0011] The side wall of the dropper disposal tank is also equipped with a horizontal telescopic component and a vertical telescopic component, both driven simultaneously by an electric telescopic component. The end of the horizontal telescopic component has an inclined guide bar, and the eye droplets accumulated at the head of the eye drop bottle are positioned along the movement path of the guide bar. The bottom end of the vertical telescopic component has a retaining block that abuts against the upper eyelid. An electronic tag identification module is installed inside the mounting slot. The controller includes the following modules:
[0012] Production Date Recognition and Analysis Module: This module scans the electronic tag on the eye drop bottle using the electronic tag recognition module to obtain the bottle's material model, production date, and capacity specifications. It then compares the production date with the current time and generates an alarm message if the analysis result indicates that the product has expired.
[0013] Liquid level analysis module: used to acquire the potentiometer rotation information when the laser receiver changes from not receiving a laser signal to receiving a laser signal, and analyze the remaining volume information of the eye drops based on the rotation information, material type and capacity specification;
[0014] Dropping Assist Module: When the laser receiver changes from not receiving a laser signal to receiving a laser signal, it controls the electric telescopic component to drive the horizontal telescopic component and the vertical telescopic component, so that the guide rod moves horizontally to contact the eye droplets accumulated at the head of the eye drop bottle, and the clamping block at the bottom of the vertical telescopic component presses against the upper eyelid.
[0015] Furthermore, the extrusion assembly includes a lead screw horizontally arranged on the inner wall of the mounting groove, a first extrusion slider and a second extrusion slider that move in opposite directions on the lead screw, a potentiometer connected to one end of the lead screw and a reset torsion spring provided thereon, a first bevel gear provided at the other end of the lead screw, the first bevel gear meshing with a second bevel gear, the second bevel gear being coaxially connected to a driven wheel, and the driven wheel meshing with an extrusion adjusting wheel rotatably connected to the outer side of the housing.
[0016] Furthermore, the horizontal telescopic component and the vertical telescopic component are driven simultaneously by a wedge block, which is driven by an electric telescopic component installed inside the housing. The moving path of the wedge block is a 45° angle between the moving directions of the horizontal telescopic component and the vertical telescopic component.
[0017] Furthermore, the horizontal telescopic component includes a horizontal slider that slides horizontally within the housing. One end of the horizontal slider is connected to a first return spring, and the other end is a first wedge-shaped portion. A connecting rod is horizontally positioned and perpendicular to the horizontal slider in the middle of the horizontal slider. An inclined guide rod is provided at the end of the connecting rod. The vertical telescopic component includes a vertical slider that slides vertically within the housing. The upper end of the vertical slider is a second wedge-shaped portion, and the lower end of the vertical slider is provided with a second return spring and a connecting rod arranged in parallel. A pressing block that abuts against the upper eyelid is provided at the lower end of the connecting rod. The wedge-shaped block is triangular prism-shaped. The first and second wedge-shaped portions abut against the two sides of the wedge-shaped block, respectively. The electric telescopic component drives the movement of the wedge-shaped block in the diagonal direction of the horizontal slider and the vertical sliding movement direction, so that the horizontal telescopic component and the vertical telescopic component move simultaneously.
[0018] Furthermore, a ratchet is coaxially connected to the second bevel gear, and a magnet is provided on the pawl of the ratchet. An electromagnet is provided inside the housing, and the electromagnet is electrically connected to the controller. The controller includes the following modules:
[0019] Droplet limiting module: When an alarm message is received, it energizes the electromagnet to attract the magnet on the pawl, causing the ratchet to disconnect from the pawl.
[0020] Furthermore, the controller also includes the following modules:
[0021] The electronic tag stores the type of eye drop corresponding to the eye drop bottle, the unit volume of one drop of eye drop corresponding to the bottle opening diameter, and the total volume of eye drop.
[0022] Capacity calculation module: used to count and count the number of times the dripping auxiliary module is started, calculate the consumed capacity based on the unit capacity, and then analyze the total capacity to obtain the remaining capacity information;
[0023] Comparison Analysis Module: This module compares the remaining capacity information analyzed by the liquid level analysis module with the calculated remaining capacity information. If the difference is within the threshold range, it outputs either the calculated remaining capacity information or the remaining capacity information. If the difference is not within the threshold range, it outputs the average of the calculated remaining capacity information and the remaining capacity information.
[0024] Furthermore, the electric telescopic component is a miniature servo electric cylinder.
[0025] Furthermore, the mounting groove is provided with a first limiting component and a second limiting component arranged opposite to each other. The first limiting component includes a first slider and a third return spring disposed between the first slider and the inner wall of the mounting groove. The second limiting component includes a second slider and a fourth return spring disposed between the second slider and the inner wall of the mounting groove. The movement directions of the first and second pressing sliders and the first and second sliders are perpendicular to each other. The first and second sliders are used to center and adjust the placement state of the eye drop bottle.
[0026] Furthermore, the housing is equipped with a speaker and a display screen. The speaker is used to broadcast alarm prompts, and the display screen is used to display the material model, production date, and capacity specifications of the eye drop bottle, as well as the remaining capacity information of the analyzed eye drops.
[0027] The second objective of this invention is to provide a method for using an auxiliary eye drop dispensing device, which utilizes the aforementioned auxiliary eye drop dispensing device and specifically includes the following steps:
[0028] S1. After placing the eye drop bottle upside down in the mounting slot, the electronic tag recognition module scans the electronic tag on the eye drop bottle to obtain the material model, production date and capacity specifications of the eye drop bottle. The production date is compared with the current time. If the analysis result is that it is expired, an alarm message is generated.
[0029] S2. If no alarm prompt is generated, a prompt is generated to allow the user to turn the squeezing adjustment wheel. This prompt is used to transmit the power of turning the squeezing adjustment wheel to the driven wheel, the second bevel gear and the first bevel gear in sequence. The first bevel gear drives the lead screw to rotate, thereby causing the first squeezing slider and the second squeezing slider to move towards each other to squeeze the eye drop bottle.
[0030] S3. When the laser receiver changes from never receiving a laser signal to receiving a laser signal, acquire the rotation information of the potentiometer, and analyze the remaining capacity information of the eye drops based on the rotation information, material type and capacity specification.
[0031] At the same time, the electric telescopic component drives the horizontal telescopic component and the vertical telescopic component, so that the guide bar moves horizontally to contact the eye droplets accumulated at the head of the eye drop bottle, and the clamping block at the bottom of the vertical telescopic component presses against the upper eyelid.
[0032] Principles and advantages:
[0033] 1. After placing the eye drop bottle upside down in the mounting slot, the electronic tag recognition module scans the electronic tag on the eye drop bottle to obtain the material model, production date, and capacity specifications of the eye drop bottle. The production date recognition and analysis module compares the production date with the current time. If the analysis result indicates that the product is expired, an alarm message is generated. This avoids situations where the exact expiration date of the opened eye drops is unknown, which can easily lead to the eye drops expiring without being used, or even worsening of the patient's eye condition.
[0034] 2. If no alarm message is generated, it means the device is usable. A prompt message will be generated instructing the user to turn the squeeze adjustment wheel. The user then simply turns the squeeze adjustment wheel. Simultaneously, the power of the squeeze adjustment wheel is transmitted sequentially to the driven wheel, the second bevel gear, and the first bevel gear, achieving a reversal. This causes the first bevel gear to drive the lead screw, causing the first and second squeeze sliders to move towards each other, squeezing the eye drop bottle. The precise positioning of the lead screw ensures that the first and second squeeze sliders slowly squeeze the eye drop bottle, avoiding excessive force and waste.
[0035] 3. When the laser beam emitted by the laser emitter strikes the liquid, refraction and scattering occur, forming a light spot. Therefore, when the laser receiver transitions from receiving a laser signal to receiving one, it acquires the rotation information of the potentiometer. This rotation information indicates the degree of compression exerted on the eye drop bottle by the first and second pressure sliders. Based on this rotation information, material type, and capacity specifications, the remaining capacity of the eye drops can be further analyzed, allowing users to promptly replace the eye drops. Furthermore, comparative analysis yields a more accurate estimate of the remaining capacity.
[0036] While analyzing the remaining volume of the eye drops, the controller also controls the electric telescopic components to drive the horizontal and vertical telescopic parts. The horizontal telescopic component moves the guide rod horizontally to contact the accumulated eye droplets at the head of the bottle, breaking the surface tension of the droplets and allowing them to drip smoothly along the rod, achieving a drop-by-drop effect. This avoids the problem of excessive squeezing of the bottle by the user, which would lead to waste. Simultaneously, driving the horizontal telescopic component also moves the bottom of the vertical telescopic component downwards, causing the clamping block at the bottom of the vertical telescopic component to press against the upper eyelid. This prevents the user from blinking while administering the drops, thus preventing the drops from entering the eye, and also avoids situations where the drops are misplaced due to unsteady hand movements, requiring repeated application.

[0040] Example
[0041] An ophthalmic eye drop auxiliary instillation device, basically as follows: Figure 1 As shown, the device includes a housing 1 and a controller. The housing 1 is a quadrangular prism. The upper surface of the housing 1 has a mounting groove for placing an inverted eye drop bottle 6. The inner wall of the mounting groove has a squeezing assembly for squeezing the eye drop bottle. The squeezing assembly includes a horizontally mounted lead screw 5 on the inner wall of the mounting groove. The lead screw 5 has a first squeezing slider 4 and a second squeezing slider 23 that move in opposite directions. A guide rod is arranged parallel to the lead screw 5. The first squeezing slider 4 and the second squeezing slider 23 are slidably connected to the guide rod to achieve a rotational limiting effect. A buffer layer 24, which is a sponge layer, is provided on the upper edge of the mounting groove on the housing 1 to facilitate the fixing of eye drop bottles 6 of different sizes.
[0042] One end of the lead screw 5 is connected to the potentiometer 2 and is provided with a reset torsion spring 3. The other end of the lead screw 5 is provided with a first bevel gear 22, which meshes with a second bevel gear 21. The second bevel gear 21 rotates horizontally. The second bevel gear 21 is coaxially connected to a driven wheel 17, which meshes with a compression adjustment wheel 16 rotatably connected to the outer side of the housing 1. The potentiometer 2 is fixed on the inner wall of the mounting groove and is provided with a bracket. The reset torsion spring 3 is sleeved on the lead screw 5, with one end fixed to the bracket and the other end fixed to the lead screw 5.
[0043] The second bevel gear 21 is coaxially connected to a ratchet 19, and a magnet is provided on the pawl 18 of the ratchet 19. An electromagnet is provided inside the housing 1. The rotating shafts of the second bevel gear 21, the driven gear 17, and the ratchet 19 are fixed to the inner wall of the mounting groove via a bearing seat 20. The pawl 18 is rotatably connected to the bearing seat 20 via the rotating shaft, and the electromagnet is fixedly mounted on the inner wall of the mounting groove via a mounting bracket.
[0044] The bottom of the mounting groove is provided with a through hole for the head of the eye drop bottle 6 to pass through. Below the through hole is a drop treatment groove. A laser emitter 7 is provided on one side wall of the drop treatment groove, and a laser receiver is provided on the other side. The eye drop droplets accumulated by the head of the eye drop bottle 6 are squeezed by the first squeeze slider 4 and the second squeeze slider 23 and are located on the path of the laser emitter 7 and the laser receiver.
[0045] The side wall of the dropper is also provided with a horizontal telescopic component and a vertical telescopic component. The end of the horizontal telescopic component is provided with an inclined guide rod 9. The eye droplets accumulated at the head of the eye drop bottle 6 are located on the moving path of the guide rod 9. The bottom end of the vertical telescopic component is provided with a pressing block 11 that abuts against the upper eyelid. The horizontal telescopic component and the vertical telescopic component are driven simultaneously by a wedge block 14. The wedge block 14 is driven by an electric telescopic component 15 provided in the housing 1. The moving path of the wedge block 14 is a 45° angle between the moving directions of the horizontal telescopic component and the vertical telescopic component.
[0046] The horizontal telescopic assembly includes a horizontal slider 10 that slides horizontally within the housing 1. A first return spring 8 is fixedly connected to the left end of the horizontal slider 10, and a first wedge-shaped portion is located at the right end. A connecting rod is horizontally arranged and perpendicular to the horizontal slider 10 in the middle of the horizontal slider 10. A guide rod 9 is inclined at the end of the connecting rod. The vertical telescopic assembly includes a vertical slider 13 that slides vertically within the housing 1. A second wedge-shaped portion is located at the upper end of the vertical slider 13. A second return spring 12 and a connecting rod are arranged in parallel at the lower end of the vertical slider 13. A pressing block 11 that abuts against the upper eyelid is located at the lower end of the connecting rod. The wedge-shaped block 14 is a regular triangular prism. The first wedge-shaped portion and the second wedge-shaped portion abut against the two sides of the wedge-shaped block 14, respectively. The electric telescopic assembly 15 drives the wedge-shaped block 14 to move in the diagonal direction of the horizontal slider 10 and the vertical sliding movement direction, so that the horizontal telescopic assembly and the vertical telescopic assembly move simultaneously.
[0047] The electric telescopic component 15 is a miniature servo electric cylinder. The slider on the miniature servo electric cylinder is fixedly connected to the wedge block 14 via a connecting synchronous rod. This allows the slider to synchronously drive the wedge block 14 even within a limited space. As a result, the lower end of the vertical slider 13 abuts against the user's upper eyelid with the abutment block 11, preventing the user from blinking while administering eye drops, and avoiding excessive pressure on the eyes.
[0048] The mounting groove is equipped with a first limiting component and a second limiting component arranged opposite to each other. The first limiting component includes a first slider and a third return spring disposed between the first slider and the inner wall of the mounting groove. The second limiting component includes a second slider and a fourth return spring disposed between the second slider and the inner wall of the mounting groove. The movement directions of the first pressing slider 4 and the second pressing slider 23 are perpendicular to each other. The first slider and the second slider are used to center and adjust the placement of the eye drop bottle 6. The height of the first slider and the second slider is located below the first pressing slider 4 and the second pressing slider 23 to avoid interference.
[0049] The housing 1 is equipped with a speaker and a display screen. The speaker is used to broadcast alarm prompts, and the display screen is used to display the material model, production date and capacity specifications of the eye drop bottle 6, as well as the remaining capacity information of the analyzed eye drops.
[0050] An electronic tag recognition module is installed in the mounting slot. The electronic tag recognition module is an NFC electronic tag recognition module, which includes a chip module and an antenna module. The antenna module is located in the mounting slot. The electronic tag recognition module, the electric telescopic component 15, and the potentiometer 2 are all electrically connected to the controller. The controller includes the following modules:
[0051] Production date identification and analysis module: used to scan the electronic tag on the eye drop bottle 6 through the electronic tag identification module to obtain the material model, production date and capacity specification of the eye drop bottle 6, and compare the production date with the current time. If the analysis result is that it is expired, an alarm prompt message is generated; the electronic tag is a sticker type electronic tag.
[0052] Droplet limiting module: When an alarm signal is received, energizing the electromagnet attracts the magnet on the pawl 18, disengaging the ratchet 19 from the pawl 18. When no alarm signal is received, energizing the electromagnet repels the magnet on the pawl 18, engaging the ratchet 19 with the pawl 18.
[0053] Liquid level analysis module: This module acquires the rotation information of potentiometer 2 when the laser receiver transitions from receiving a laser signal to receiving one. Based on this rotation information, material type, and capacity specification, it analyzes the remaining capacity of the eye drops. In this embodiment, it specifically utilizes existing mature neural network models for predictive analysis, such as Feedforward Neural Network (FNN), Recurrent Neural Network (RNN), Convolutional Neural Network (CNN), and Generative Adversarial Network (GAN). Material types include LDPE, PET, and PVC. The total capacity of the eye drops typically ranges from 2.5ml to 20ml.
[0054] The electronic tag stores the type of eye drop corresponding to the eye drop bottle 6, the unit volume of one drop of eye drop, the diameter of the bottle opening, and the total volume of eye drop; typically, the unit volume of one drop of eye drop is between 0.04 ml and 0.05 ml.
[0055] Capacity calculation module: used to count and count the number of times the dripping auxiliary module is started, calculate the consumed capacity based on the unit capacity, and then analyze the total capacity to obtain the remaining capacity information;
[0056] Comparison Analysis Module: This module compares the remaining capacity information analyzed by the liquid level analysis module with the calculated remaining capacity information. If the difference is within the threshold range, it outputs either the calculated remaining capacity information or the remaining capacity information. If the difference is not within the threshold range, it outputs the average of the calculated remaining capacity information and the remaining capacity information.
[0057] Dropping Assist Module: When the laser receiver changes from never receiving a laser signal to receiving a laser signal, it controls the electric telescopic component 15 to drive the horizontal telescopic component and the vertical telescopic component, so that the guide rod 9 moves horizontally to contact the eye droplets accumulated at the head of the eye drop bottle 6, and so that the clamping block 11 at the bottom of the vertical telescopic component presses against the upper eyelid.
[0058] When using this solution, the eye drop bottle is placed upside down in the mounting slot. The electronic tag recognition module scans the electronic tag on the eye drop bottle to obtain the bottle's material model, production date, and capacity specifications. The production date recognition and analysis module compares the production date with the current time. If the analysis result indicates that the product is expired, an alarm message is generated. This avoids situations where the expiration date of the opened eye drops is unknown, which can easily lead to the eye drops expiring without being used, or even worsening of the patient's eye condition.
[0059] If no alarm message is generated, it means the device is ready to use. A prompt message will be generated instructing the user to turn the squeeze adjustment wheel. The user then simply turns the squeeze adjustment wheel. Simultaneously, the power is transmitted sequentially to the driven wheel, the second bevel gear, and the first bevel gear, causing a reversal. This allows the first bevel gear to drive the lead screw, causing the first and second squeeze sliders to move towards each other, squeezing the eye drop bottle. The precise positioning of the lead screw ensures that the first and second squeeze sliders slowly squeeze the eye drop bottle, avoiding excessive force and waste.
[0060] When the laser beam emitted by the laser emitter strikes the liquid, refraction and scattering occur, forming a light spot. Therefore, when the laser receiver transitions from receiving a laser signal to receiving one, it acquires the rotation information of the potentiometer. This rotation information indicates the degree of compression exerted on the eye drop bottle by the first and second pressure sliders. Based on this rotation information, material type, and capacity specifications, the remaining capacity of the eye drops can be further analyzed, allowing users to promptly replace the eye drops. Furthermore, comparative analysis yields a more accurate estimate of the remaining capacity.
[0061] While analyzing the remaining volume of the eye drops, the controller also controls the electric telescopic components to drive the horizontal and vertical telescopic parts. The horizontal telescopic component moves the guide rod horizontally to contact the accumulated eye droplets at the head of the bottle, breaking the surface tension of the droplets and allowing them to drip smoothly along the rod, achieving a drop-by-drop effect. This avoids the problem of excessive squeezing of the bottle by the user, which would lead to waste. Simultaneously, driving the horizontal telescopic component also moves the bottom of the vertical telescopic component downwards, causing the clamping block at the bottom of the vertical telescopic component to press against the upper eyelid. This prevents the user from blinking while administering the drops, thus preventing the drops from entering the eye, and also avoids situations where the drops are misplaced due to unsteady hand movements, requiring repeated application.
[0062] A method for using an ophthalmic eye drop auxiliary instillation device, employing the ophthalmic eye drop auxiliary instillation device as described above, specifically includes the following steps:
[0063] S1. After placing the eye drop bottle 6 upside down in the mounting slot, scan the electronic tag on the eye drop bottle 6 using the electronic tag recognition module to obtain the material model, production date and capacity specifications of the eye drop bottle 6, and compare the production date with the current time. If the analysis result is that it has expired, an alarm message will be generated.
[0064] S2. If no alarm prompt is generated, a prompt is generated to allow the user to turn the squeezing adjustment wheel 16. This prompt is used to transmit the power of turning the squeezing adjustment wheel 16 to the passive wheel 17, the second bevel gear 21 and the first bevel gear 22 in sequence. This causes the first bevel gear 22 to drive the lead screw 5 to rotate, thereby causing the first squeezing slider 4 and the second squeezing slider 23 to move towards each other and squeeze the eye drop bottle 6.
[0065] S3. When the laser receiver changes from never receiving a laser signal to receiving a laser signal, obtain the rotation information of potentiometer 2, and analyze the remaining capacity information of the eye drops based on the rotation information, material type and capacity specification.
[0066] At the same time, the electric telescopic component 15 drives the horizontal telescopic component and the vertical telescopic component, so that the guide rod 9 moves horizontally to contact the eye droplets accumulated at the head of the eye drop bottle 6, and so that the clamping block 11 at the bottom of the vertical telescopic component presses against the upper eyelid.
[0067] S4. Count and count the number of times the dripping auxiliary module is started, calculate the consumed capacity based on the unit capacity, and then analyze the total capacity to obtain the remaining capacity information.
[0068] S5. Compare and analyze the remaining capacity information analyzed by the liquid level analysis module with the calculated remaining capacity information. If the difference is within the threshold range, output the calculated remaining capacity information or the remaining capacity information; if the difference is not within the threshold range, output the average of the calculated remaining capacity information and the remaining capacity information.
