Description

Technical Field

[0001] The present invention relates to the technical field of eye drop instillation, and specifically to an automatic eye drop instillation positioning assistor. Background Art

[0002] Eye drops can play an effective role in alleviating and treating in actual ophthalmic surgeries and daily eye dryness. Eye drops are widely used among the elderly population. When instilling eye drops, it is necessary to maintain accuracy and ensure that the eye drops are instilled into the eyelid. The head is tilted back, the eyes look up, and the index finger of one hand is gently used to pull down the lower eyelid for eye drop instillation. Currently, the automatic eye drop instillation positioning assistor benefits from the setting of structures such as a reflector, which is convenient for patients to observe and has been widely used. However, the current automatic eye drop instillation positioning assistor is not convenient for closing the lacrimal sac. The eye drops flow into the nasal cavity through the nasolacrimal duct and are then absorbed by the nasal mucosa and enter the systemic circulation, which is likely to cause unnecessary side effects. At the same time, the amplitude of the head tilt when the patient is using it is not easy to control. If there is an inclination, the eye drops will quickly flow out from the corner of the eye, affecting the curative effect. It is not convenient to perform instillation after body position detection, nor is it convenient to automatically control the lifting of the eyelid. Traditional operations such as pulling down with fingers cause the eyelid to turn outwards, resulting in poor comfort and also not being convenient for retaining the eye drops.

[0003] Therefore, we propose an automatic eye drop instillation positioning assistor. Summary of the Invention

The dropping liquid level limiting part 4 can be used to ensure that the patient's head can lean back and remain relatively horizontal when using this structure, so as to prevent the medicine from overflowing quickly because the patient does not lean back the head when dropping eye drops, and can keep the medicine staying in the eyelid. The dropping liquid storage part 3 can facilitate the storage of eye drops. This structure is flexible in use and can realize automatic quantitative dropping of eye drops. Under the traction of the counterweight of the counterweight ring 402, the rotating limit cover 401 can rotate and adjust inside the ball sleeve 304. When the patient's head leans back to a reasonable horizontal range, at this time the counterweight ring 402 can pull the rotating limit cover 401, and 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 normally pass through the through hole 4011 to ensure that when using this structure for dropping, the patient's head leans back.

[0038] Among them, the liquid dripping pressing member 5 includes: a lower pressing cover 501, a corrugated pipe 502, and a spring 503. The lower pressing cover 501 is slidably sleeved in the liquid storage barrel 301; a corrugated pipe 502 is fixedly installed at the bottom of the lower pressing cover 501, and the end of the corrugated pipe 502 is fixedly connected to the inner side of the liquid storage barrel 301; a spring 503 is sleeved outside the corrugated pipe 502; the end of the spring 503 is fixedly installed at the bottom of the lower pressing cover 501; the other end of the spring 503 is fixedly installed on the inner side of the liquid storage barrel 301; the liquid dripping control member 6 includes: a liquid dripping sliding shell 601, an anti-misoperation spring 602, and a microswitch 603. The liquid dripping sliding shell 601 is slidably installed on the lower pressing cover 501; an anti-misoperation spring 602 is fixedly installed at the bottom of the liquid dripping sliding shell 601, and the end of the anti-misoperation spring 602 is fixedly installed on the liquid dripping sliding shell 601 of the lower pressing cover 501; a microswitch 603 is fixedly installed on the lower pressing cover 501, and the microswitch 603 is attached to the liquid dripping sliding shell 601; the liquid dripping sliding shell 601 is located below the electric push rod 305; the liquid suction and storage member 7 includes: a liquid suction swing arm 701, a separation electromagnet 702, and an adsorption cover 703.

By using the liquid dropping control member 6, it is convenient to automatically control the raising of the patient's eyelid when dropping liquid. The negative pressure method will not damage the patient's eyelid. At the same time, in cooperation with the suction liquid storage member 7, this structure uses the method of raising the patient's eyelid, which is more convenient for eye drops to accumulate in the patient's eyelid. This structure can raise the upper and lower eyelids of the patient at the same time. Compared with the traditional method of pulling the patient's eyelid downward and turning it outward, less eye drops are lost in this structure, which is convenient for the eyelid to absorb, and it can avoid the eye drops flowing directly from the eyelid through the corner of the eye just after being dropped. This structure does not require manual control to lift the eyelid, is safe and reliable. By simultaneously receiving the dropped eye drops with the upper and lower eyelids, the loss is reduced. This structure can automatically control the time for the patient to lift the eyelid by using the liquid dropping control member 6, avoiding the problem of dry eyes caused by continuous everted eyelids. This structure is automatically controlled, and the patient feels more comfortable when using it. When the output shaft of the electric push rod 305 extends, it can first touch the liquid dropping sliding shell 601 and then squeeze the micro switch 603. At this time, the micro switch 603 will control the separation electromagnet 702 and the fixed electromagnet 104 to be energized and repel each other. At this time, the suction swing arm 701 will rotate upward, lifting the adsorption cover 703, and the upper and lower eyelids can be lifted respectively. By using the rubber drain port 3012 with a rubber elastic structure, the sealing performance can be guaranteed while not affecting the discharge of eye drops. After the electric push rod 305 pushes the lower pressing cover 501 downward, eye drops can be squeezed out. After the eye drops are dropped between the upper and lower eyelids and the eyeball, under the extrusion of the spring 503, when the output shaft of the electric push rod 305 retracts and resets, the lower pressing cover 501 and the corrugated pipe 502 can be squeezed and rise and reset together, and the use is simple and comfortable.;

[0039] Embodiment 2, on the basis of Embodiment 1, the close contact detection member 8 includes: an in-place elastic piece 801 and a power connection fixing piece 802. The in-place elastic piece 801 is fixedly installed at the bottom of the orbital fitting ring 101; an insulating coating is provided at the bottom of the in-place elastic piece 801; the power connection fixing piece 802 is fixedly installed at the bottom of the orbital fitting ring 101; the in-place elastic piece 801 is aligned with the power connection fixing piece 802; the in-place elastic piece 801 is an elastic structure; the in-place elastic piece 801, the power connection fixing piece 802 and the switch 306 are connected in series to the power supply. By using the close contact detection member 8, it is convenient to detect that the orbital fitting ring 101 is completely fitted to the orbit when the patient uses it, so as to control this structure to perform the dropping operation. In cooperation with the liquid dropping level limiting member 4, the anti-misoperation effect of this structure is further ensured, and at the same time, the standardization and success rate of the patient dropping eye drops are improved. The detection method by the in-place elastic piece 801 is simple and direct, and more reliable, which can prevent the patient from dropping eye drops non-standardly, resulting in the failure of the drug effect to act on the eye normally. When the orbital fitting ring 101 is completely fitted to the orbit, at this time, the in-place elastic piece 801, the power connection fixing piece 802 and the switch 306 are in a conducting state, and the patient can directly operate and press the switch 306 to perform the dropping operation.

[0040] Working principle of this embodiment: First, the patient lies flat or sits with the head tilted back. By attaching the orbital fitting ring 101 to the orbit, the lacrimal sac positioning shaft 201 can be attached to the lacrimal sac. Under the pull of the tension spring 202, the lacrimal sac can be pressed for blocking. The liquid absorption pad 102 can absorb the overflowing eye drops and tears. Eye drops are put into the liquid storage barrel 301, and then the sealing plug 3011 is tightened for sealing. This structure can be driven for dropping work by the electric push rod 305. When using this structure to fit on the orbit, at this time, under the counterweight traction of the counterweight ring 402, the rotation limiting cover 401 can rotate and adjust inside the ball sleeve 304. When the patient's head is tilted back within a reasonable horizontal range, at this time, the counterweight ring 402 can traction the rotation limiting cover 401, and 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 normally pass through the through hole 4011. On the contrary, when the patient's head is tilted back insufficiently, under the counterweight traction of the counterweight ring 402, the electric push rod 305 will be misaligned with the through hole 4011, and at this time, the electric push rod 305 cannot be normally pushed out;

[0041] When the orbital fitting ring 101 is attached to the orbit, at this time, the bone at the orbit will squeeze the in-place elastic piece 801. The in-place elastic piece 801 will elastically deform under pressure and fit the power connection fixing piece 802. At this time, the in-place elastic piece 801, the power connection fixing piece 802 and the switch 306 are in a conducting path. Pressing the switch 306 can control the electric push rod 305 to slowly press down to control the extrusion of eye drops, and also control the start of the electric blower 3021 to suck air. When the electric blower 3021 starts, the adsorption cover 703 is also driven to be negatively adsorbed and fit on the upper and lower eyelids at the same time. 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 switch 603. At this time, the micro switch 603 will control the separation electromagnet 702 and the fixed electromagnet 104 to be energized and repelled. At this time, the suction swing arm 701 will rotate upward, lifting the adsorption cover 703, and 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, at this time, the pressing cover 501 can be pressed down, and the eye drops in the liquid storage barrel 301 are discharged through the rubber drainage port 3012. The rubber drainage port 3012 with a rubber elastic structure can ensure the sealing performance while not affecting the discharge of eye drops, and realize the standard dropping of eye drops between the upper and lower eyelids and the eyeball.
