Description

Technical Field

[0001] This invention relates to the field of eye drop application technology, specifically to an automatic eye drop application and positioning aid. Background Technology

[0002] Eye drops can effectively relieve and treat dry eyes after ophthalmic surgery and in daily life. They are widely used among the elderly. When administering eye drops, precision is crucial. To ensure the drops are placed on the eyelid, tilt the head back, look upwards, and gently pull down the lower eyelid with the index finger of one hand to apply the drops. Current automatic eye drop applicators, thanks to features like reflectors, facilitate patient observation and are widely used. However, these devices do not effectively close the lacrimal sac, allowing the drops to flow into the nasal cavity through the nasolacrimal duct and be absorbed into the systemic circulation, potentially causing unnecessary side effects. Furthermore, the degree of head tilt is difficult to control; tilting the head can cause the drops to flow rapidly from the corner of the eye, affecting efficacy. They also hinder positional detection before application and automatic eyelid lifting. Traditional finger-pulling methods result in eyelid eversion, discomfort, and poor drop retention.

[0003] Therefore, we propose an automatic eye drop dispensing and positioning aid. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The present invention uses a lacrimal sac positioning component that can be easily attached and pressed onto the lacrimal sac. In actual eye drop application, it can play a protective role. Pressing the lacrimal sac can prevent eye drops from flowing into the nasal cavity through the nasolacrimal duct and then being absorbed by the nasal mucosa into the systemic circulation, causing unnecessary side effects.

[0017] The liquid level limiting component is used to ensure that the patient's head can be tilted back and kept relatively horizontal when using this structure. This prevents the eye drops from overflowing rapidly because the patient's head is not tilted back. It keeps the eye drops inside the eyelid. Under the counterweight traction of the counterweight ring, the rotating limiting cover can rotate and adjust inside the ball sleeve to limit the electric push rod.

[0018] The drip control device allows for automatic control of lifting the patient's eyelids during dripping. The negative pressure method prevents damage to the patient's eyelids. This structure makes it easier for the eye drops to accumulate in the eyelids by lifting them. This structure can lift the upper and lower eyelids simultaneously. Compared to the traditional method of pulling the patient's eyelids down and everting, this structure results in less eye drop loss, facilitates eyelid absorption, and is more comfortable to use.

[0019] The use of a close-fitting detection element ensures that the eye socket fitting ring is completely in contact with the eye socket when the patient uses the device, thus controlling the dispensing process. Combined with the dispensing level limiting element, this further guarantees the device's anti-accidental activation effect, while improving the standardization and success rate of eye drop dispensing for patients, making it more suitable for elderly patients.

[0034] Example 1: Please refer to Figures 1-12 As shown:

[0035] This invention provides a technical solution: an automatic eye drop dispensing and positioning aid, comprising an orbital fitting 1, a lacrimal sac positioning component 2 mounted on the orbital fitting 1 for fitting and pressing the lacrimal sac; a drop-in reservoir 3 mounted on the orbital fitting 1 for storing eye drops; a drop-in level limiting component 4 mounted on the drop-in reservoir 3; and a drop-in pressing component 5 mounted on the drop-in reservoir 3. The drop-in level limiting component 4 limits the position of the drop-in pressing component 5; the drop-in pressing component 5 is used for pressing down.

[0036] The orbital fitting component 1 further includes: a support frame 103 and a fixing electromagnet 104. The support frame 103 is fixedly installed on the orbital fitting ring 101; two fixing electromagnets 104 are fixedly installed on the support frame 103. The lacrimal sac positioning component 2 includes: a lacrimal sac positioning shaft 201 and a tension spring 202. The lacrimal sac positioning shaft 201 is slidably installed on the orbital fitting ring 101; a tension spring 202 is sleeved on the lacrimal sac positioning shaft 201; one end of the tension spring 202 is connected to the lacrimal sac positioning shaft 201; the other end of the tension spring 202 is fixedly installed on the orbital fitting ring 101. The bottom of the lacrimal sac positioning shaft 201 is an arc-shaped hemispherical structure. The lacrimal sac positioning component 2 can be easily pressed against the lacrimal sac. In actual eye drop application, it can play a protective role. Pressing the lacrimal sac can prevent eye drops from flowing into the nasal cavity through the nasolacrimal duct and then being absorbed by the nasal mucosa into the systemic circulation, causing unnecessary side effects. It can also prevent tear reflux, making it more practical. This structure uses an absorbent pad 102 to absorb spilled eye drops and tears, preventing spilled eye drops from flowing into the mouth or other places and causing accidental ingestion.

[0037] The liquid storage unit 3 includes: a storage tank 301, a sealing plug 3011, a rubber drain outlet 3012, an exhaust pipe 302, an electric fan 3021, and a suction pipe 303. The storage tank 301 is fixedly mounted on the support frame 103. The sealing plug 3011 is threadedly connected to the side of the storage tank 301. The bottom of the storage tank 301 is provided with a rubber drain outlet 3012.

The structure includes a rotating limiting cover 401, a through hole 4011, and a counterweight ring 402. The rotating limiting cover 401 is a spherical structure with a through hole 4011 in the middle. The rotating limiting cover 401 is fitted onto a spherical sleeve 304. A counterweight ring 402 is fixedly installed at the bottom of the rotating limiting cover 401. An electric push rod 305 passes through the through hole 4011. A liquid level limiting component 4 is used to ensure that the patient's head can be tilted back and kept relatively horizontal when using this structure, preventing the eye drops from overflowing rapidly because the patient's head is not tilted back. The eye drops are retained inside the eyelid and can be easily stored through the drip collection part 3. This structure is flexible and can realize automatic quantitative dripping of eye drops. Under the traction of the counterweight ring 402, the rotating limit cover 401 can be rotated and adjusted inside the ball sleeve 304. When the patient's head is tilted back to a reasonable horizontal range, the counterweight ring 402 can pull the rotating limit cover 401. At this time, the through hole 4011 can be aligned with the electric push rod 305. The output shaft of the electric push rod 305 can pass through the through hole 4011 normally, ensuring that the patient's head is tilted back when using this structure for dripping.

[0038] The dripping pressing component 5 includes: a lower pressing cap 501, a bellows tube 502, and a spring 503. The lower pressing cap 501 is slidably sleeved inside the liquid storage tank 301. The bellows tube 502 is fixedly installed at the bottom of the lower pressing cap 501, and the end of the bellows tube 502 is fixedly connected to the inside of the liquid storage tank 301. The spring 503 is sleeved on the outside of the bellows tube 502. The end of the spring 503 is fixedly installed at the bottom of the lower pressing cap 501. The other end of the spring 503 is fixedly installed inside the liquid storage tank 301. The dripping control component 6 includes: a dripping sliding shell 601, an anti-accidental touch spring 602, and a micro switch 603. The dripping sliding shell 601 is slidably installed on the lower pressing cap 501. The anti-accidental touch spring 602 is fixedly installed at the bottom of the dripping sliding shell 601, and the end of the anti-accidental touch spring 602 is fixedly installed inside the liquid storage tank 301. A liquid-drip sliding shell 601 is mounted on the lower pressure cap 501; a micro switch 603 is fixedly installed on the lower pressure cap 501 and is attached to the liquid-drip sliding shell 601; the liquid-drip sliding shell 601 is located below the electric push rod 305; the suction and storage component 7 includes: a suction swing arm 701, a separation electromagnet 702, and an adsorption cover 703; the suction swing arm 701 is rotatably mounted on the eye socket fitting ring 101; the separation electromagnet 702 is fixedly installed on the suction swing arm 701; the separation electromagnet 702 is aligned with the fixing electromagnet 104; the adsorption cover 703 is fixedly installed on the suction swing arm 701, and a suction tube 303 is fixedly installed on the adsorption cover 703; the adsorption cover 703 is used to adhere to the upper and lower eyelids; the micro switch 603 is electrically connected to the separation electromagnet 702.When the separating electromagnet 702 and the fixed electromagnet 104 are energized, they repel each other. The drip control component 6 allows for automatic control of lifting the patient's eyelids during dripping. The negative pressure method prevents damage to the patient's eyelids. Combined with the suction and storage component 7, this structure, by lifting the patient's eyelids, facilitates the accumulation of eye drops. This structure can lift both the upper and lower eyelids simultaneously. Compared to the traditional method of pulling the eyelids down and everting them, this structure results in less eye drop loss and facilitates absorption by the eyelids. It prevents the eye drops from flowing directly from the eyelids and outwards from the corner of the eye immediately after application. This structure requires no manual control of lifting the eyelids, making it safe and reliable. By simultaneously receiving the dripped eye drops through both the upper and lower eyelids, loss is reduced. The drip control component 6 automatically controls the duration of eyelid lifting, avoiding the dryness caused by continuous eversion of the eyelids. This structure features automatic control, enhancing patient comfort. When the output shaft of the electric push rod 305 extends, it first touches the drip sliding shell 601 and then squeezes the micro switch 603. At this point, the micro switch 603 controls the separation electromagnet 702 to repel the fixed electromagnet 104, causing the suction arm 701 to rotate upwards and lift the suction cover 703. The upper and lower eyelids can then be lifted separately. The rubber drainage port 3012, with its elastic rubber structure, ensures a tight seal without affecting the drainage of the eye drops. The electric push rod 305 pushes the lower pressure cap 501 down, squeezing out the eye drops. After the eye drops are dripped between the upper and lower eyelids and the eyeball, under the pressure of the spring 503, when the output shaft of the electric push rod 305 retracts and resets, the lower pressure cap 501 and the bellows 502 can be squeezed and lifted back to their original positions. The process is simple and comfortable to use.

[0039] Example 2, based on Example 1, includes the following closely attached detection element 8: a positioning spring 801 and a power-connecting fixing piece 802. The positioning spring 801 is fixedly installed at the bottom of the orbital fitting ring 101; the bottom of the positioning spring 801 is provided with an insulating coating; the power-connecting fixing piece 802 is fixedly installed at the bottom of the orbital fitting ring 101; the positioning spring 801 is aligned with the power-connecting fixing piece 802; the positioning spring 801 is an elastic structure; the positioning spring 801, the power-connecting fixing piece 802, and the switch 306 are connected in series with a power supply. Using the closely attached detection element 8 facilitates testing of the orbital fitting ring 101 during patient use. 01 This structure can only be controlled to perform the dripping operation when it is completely fitted to the eye socket. In conjunction with the dripping level limiting component 4, the structure is further guaranteed to prevent accidental activation. At the same time, it improves the standardization and success rate of patients' eye drop application. The detection method through the positioning spring 801 is simple, direct and more reliable. It can prevent patients from not applying eye drops according to the standard, which would prevent the medicine from acting normally on the eye. When the eye socket fitting ring 101 is completely fitted to the eye socket, the positioning spring 801, the power connection fixing piece 802 and the switch 306 are in operation. The patient can directly operate the switch 306 to perform the dripping operation.

[0040] The working principle of this embodiment is as follows: First, the patient lies flat or sits with their head tilted back. The eye socket fitting ring 101 is then placed on the eye socket. The lacrimal sac positioning shaft 201 is used to fit the lacrimal sac. The tension spring 202 is used to pull and press the lacrimal sac to create a barrier. The absorbent pad 102 absorbs any overflowing eye drops and tears. Eye drops are then added to the storage container 301 and sealed with the sealing plug 3011. This structure is driven by an electric push rod 305 for dispensing. When this structure is fitted onto the eye socket, the counterweight ring... Under the traction of the counterweight 402, the rotating limit cover 401 can rotate and adjust inside the ball sleeve 304. When the patient's head is tilted back to a reasonable horizontal range, the counterweight ring 402 can pull the rotating limit cover 401. At this time, the through hole 4011 can be aligned with the electric push rod 305, and the output shaft of the electric push rod 305 can pass through the through hole 4011 normally. Conversely, when the patient's head is not tilted back enough, the electric push rod 305 will be misaligned with the through hole 4011 under the traction of the counterweight ring 402, and the electric push rod 305 cannot be pushed out normally.

[0041] When the eye socket fitting ring 101 is applied to the eye socket, the bone at the eye socket will compress the positioning spring 801. The positioning spring 801 will elastically deform under pressure and fit into the power connection fixing piece 802. At this time, the positioning spring 801, the power connection fixing piece 802, and the switch 306 are connected. Pressing the switch 306 will control the electric push rod 305 to slowly press down to control the expulsion of eye drops, and also control the electric fan 3021 to start suction. When the electric fan 3021 starts, the suction cover 703 is also driven and simultaneously suctioned into the upper and lower eyelids under negative pressure. At this time, when the output shaft of the electric push rod 305 extends, it can first touch the drip sliding shell 601 and then squeeze the micro-motion switch. When switch 603 is closed, the microswitch 603 will control the separation electromagnet 702 and the fixed electromagnet 104 to repel each other. At this time, the suction swing arm 701 will rotate upward and lift the suction cover 703, so that the upper and lower eyelids can be lifted separately. At the same time, as the output shaft of the electric push rod 305 continues to extend and press down, the lower cover 501 can be pressed down, and the eye drops inside the storage tank 301 can be discharged through the rubber drain port 3012. The rubber drain port 3012, with its elastic rubber structure, can ensure sealing without affecting the discharge of eye drops, so as to achieve the standardized dripping of eye drops between the upper and lower eyelids and the eyeball.
