Description

Technical Field

[0001] The present invention relates to the technical field of eye treatment, and more specifically, to an eye drop device suitable for the elderly population. Background Art

[0002] Eye drops are a very important treatment option in the treatment of ophthalmic diseases. The eye's organizational structure is delicate and unique. Eye drops can directly act on the eye surface, including key parts such as the conjunctiva and cornea. The drug quickly penetrates into the eye tissue through the tear circulation to achieve precise treatment. Taking glaucoma treatment as an example, eye drops for reducing intraocular pressure can directly act on parts such as the trabecular meshwork and ciliary body, regulate the production and drainage of aqueous humor, effectively reduce intraocular pressure, and prevent the damage of high intraocular pressure to the optic nerve.

[0003] For the elderly population with ophthalmic diseases, such as patients after cataract surgery, due to factors such as inconvenient vision and shaky hands, it has become a difficult problem to use eye drops after cataract surgery. In clinical practice, we often encounter diseases such as corneal epithelial damage and hyphema in the anterior chamber caused by eye drops. There are even cases where the eye drops are misapplied or too much eye drops overflow from the eyeball, resulting in contamination of the eye drops and causing infections. It is not easy for the elderly population to use eye drops. In view of this, we propose an eye drop device suitable for the elderly population. Summary of the Invention

[0015] The beneficial effects of the present invention are: 1. The present invention ensures the stability of the eye drop mechanism during eye treatment by providing an eye mask, and provides support for the eyes through a support mechanism to prevent the problem of the eye drops being misapplied due to blinking during the eye drop process. By providing a metering mechanism to quantitatively add drops on the eye drop mechanism and dropping the eye drops into the eye through the eye drop mechanism, it prevents the occurrence of cases of eye drop pollution and infection caused by excessive overflow of the eye drops from the eyeball, which is beneficial for the elderly to correctly and appropriately instill eye drops and solves the technical problem of difficulty in instilling eye drops for the elderly population.

[0016] 2. Through the above arrangement, the present invention enables the movable column A to move on the straight groove A and the movable column B to move on the displacement guide groove. When the air valve unit is closed and several adsorption units are in contact with the skin of the patient's eyes, two air chambers, bellows A and bellows B form a pneumatic cavity. If the movable column A and the movable column B move relatively away from each other, the volume of the pneumatic cavity increases to form a negative pressure, causing the adsorption units to generate an adsorption effect on the skin of the eyes, thereby keeping the patient's eyes in an open state and preventing the problem of the eye drops being misapplied due to blinking during the eye drop process.

[0017] 3. Through the further design of the displacement guide groove, when the movable column A and the movable column B move relatively away from each other, the movable column B first makes an arc-shaped movement on the arc groove B to conform to the shape of the eye, preventing the adsorption unit from driving the upper eyelid to move and causing excessive pressure on the convex part of the eyeball when the eyes are opened.

[0018] 4. Through the further design of the adsorption unit, when the adsorption unit drives the upper eyelid to move and the eyes are opened, the volume of the pneumatic cavity increases to form a negative pressure, causing the elastic tube to automatically shorten and drive the eyelid away from the eyeball. During eye drop instillation, the eye drops are not easily spilled, reducing the risk of infection.

[0019] 5. Through the further design of the forward thread groove and the reverse thread groove, the moving distance of the slider A is greater than that of the slider B, so that the moving distance of the adsorption unit adsorbed on the upper eyelid is greater than that of the adsorption unit adsorbed on the lower eyelid. Among them, the adsorption position of the adsorption unit adsorbed on the upper eyelid is near the eyelashes, and the specific adsorption position of the adsorption unit adsorbed on the lower eyelid is the skin near the cheek. The arc groove C provides a limiting function for the ball block B to prevent the blinking action when the patient's eyes are opened.

[0020] 6. Through the structural arrangement of the liquid dropping mechanism of the present invention, when the patient presses two clamping blocks, two movable arc blocks move within the arc groove A, the arc-shaped spring shortens, the two clamping blocks rotate relative to the rotating rod and squeeze the rubber head, causing the eye drops in the rubber head to fall along the dropper. Among them, the dropper is fixedly arranged on the fixing plate at the gap position between two movable columns B when the relative distance to the movable column A is the closest. Since the adsorption position of the adsorption unit adsorbed on the upper eyelid is close to the eyelash part, that is, arranged according to the optimal position when referring to dropping eye drops. After the eye drops are completed, the patient releases the finger. Under the elastic force of the arc-shaped spring, the two movable arc blocks and the two clamping blocks return to their original positions, and this structure is relatively labor-saving compared to the traditional method of directly pressing the eye drop bottle (especially the difficult-to-press eye drop bottle).

The adsorption component 5 is provided at the bottom of the eye mask 1. The adsorption component 5 has two adsorption ends. The opposite movement component 6 is provided on one side of the eye mask 1 relative to the positions of the two adsorption ends. The opposite movement component 6 has two moving ends, and the two moving ends are respectively connected to the two adsorption ends.

[0024] In an embodiment of the present invention, a soft pad is fixedly provided on the peripheral side of the bottom end of the eye mask 1. An empty groove 10 is opened at the bottom end of the eye mask 1. Straight grooves A11 are opened at both ends of the empty groove 10. A displacement guide groove 12 is opened on one side of the straight groove A11. A sliding cavity 13 is opened on one side of the bottom of the empty groove 10. The sliding cavity 13 is communicated with the corresponding straight groove A11 and the displacement guide groove 12. A sliding groove 14 is opened at the top end of the sliding cavity 13. A fixing plate 15 is opened at the top end of the empty groove 10. A rotating cavity 16 communicated with the empty groove 10 is opened in the middle of the eye mask 1. An arc groove A17 is opened on the rotating cavity 16. An installation groove 18 is opened at the top end of the eye mask 1. A hole groove A19 communicated with the rotating cavity 16 is opened at the bottom end of the installation groove 18.

[0025] In an embodiment of the present invention, the adsorption assembly 5 includes two installation arc blocks 51. Both of the two installation arc blocks 51 are arranged in the empty groove 10. One end of one installation arc block 51 is respectively movably connected with the two straight grooves A11 through a movable column A52, and one end of the other installation arc block 51 is respectively movably connected with the two displacement guide grooves 12 through a movable column B53. The inside of the installation arc block 51 is hollow to form an air cavity 54. The two air cavities 54 are communicated through a corrugated pipe A55. A plurality of adsorption units 56 are uniformly arranged at the bottom end of the installation arc block 51. A corrugated pipe B57 is communicated with the installation arc block 51 far from the straight groove A11. A hole groove B110 is opened at the position of the eye mask 1 opposite to the corrugated pipe B57. The corrugated pipe B57 and the hole groove B110 are fixedly connected through a gas valve unit 58. Through the above arrangement of the present invention, the movable column A52 can move on the straight groove A11, and the movable column B53 can move on the displacement guide groove 12. And when the gas valve unit 58 is closed and a plurality of adsorption units 56 are in contact with the skin of the patient's eye, the two air cavities 54, the corrugated pipe A55 and the corrugated pipe B57 form a pneumatic cavity. If the movable column A52 and the movable column B53 move relatively away from each other, the volume of the pneumatic cavity becomes larger to form a negative pressure, so that the adsorption units 56 generate an adsorption effect on the eye skin, so that the patient's eyes are kept in an open state, preventing the problem that the eye drops are misplaced due to blinking during the eye drop process.

[0026] In an embodiment of the present invention, the displacement guide groove 12 includes an arc groove B121. A straight groove B122 is opened at one end of the arc groove B121 far from the straight groove A11. Through the further design of the displacement guide groove 12 of the present invention, when the movable column A52 and the movable column B53 move relatively away from each other, the movable column B53 first makes an arc-shaped movement on the arc groove B121 to fit the shape of the eye, preventing the adsorption unit 56 from driving the upper eyelid to move and causing excessive pressure on the convex part of the eyeball when the eyes are opened.

[0027] In an embodiment of the present invention, the adsorption unit 56 includes a suction head 561, and the suction head 561 is connected to the corresponding air chamber 54 through an elastic tube 562. Among them, the middle part of the elastic tube 562 is corrugated. Through the further design of the adsorption unit 56, when the adsorption unit 56 drives the upper eyelid to move and the eyes open, the volume of the air pressure chamber becomes larger to form a negative pressure, so that the elastic tube 562 automatically shortens and drives the eyelid away from the eyeball. When instilling eye drops, it makes the eye drops not easy to overflow and reduces the risk of infection.

[0028] In an embodiment of the present invention, the air valve unit 58 includes a fixed column 581, and the fixed column 581 is fixed on the hole groove B110. One end of the fixed column 581 is fixedly connected to the bellows B57. A partial circular hole A582 communicating with the bellows B57 is opened at one end of the fixed column 581 close to the bellows B57. A rotating groove 583 is opened at the other end of the fixed column 581 away from the bellows B57. A semi-circular groove 587 is opened on the rotating groove 583. An airtight rod 584 is rotatably connected to the rotating groove 583. The airtight rod 584 is movably connected to the semi-circular groove 587 through a spherical block A585. The airtight rod 584 passes through the rotating groove 583 and extends outside the eye mask 1 and is fixedly provided with a knob A588. The knob A588 and the airtight rod 584 form an adjustment block. A partial circular hole B586 is opened on the adjustment block, and the partial circular hole B586 is in communication and cooperation with the partial circular hole A582. Through the structural design of the air valve unit 58, when the knob A588 is rotated, the airtight rod 584 rotates on the rotating groove 583. When the spherical block A585 moves to one end of the semi-circular groove 587 and the partial circular hole A582 is in communication with the partial circular hole B586, the air valve unit 58 is opened. When the spherical block A585 moves to the other end of the semi-circular groove 587 and the partial circular hole A582 is not in communication with the partial circular hole B586, the air valve unit 58 is closed. The spherical block A585 moves on the semi-circular groove 587 to assist the patient in opening and closing the air valve unit 58.

[0029] In an embodiment of the present invention, the opposing moving component 6 includes a movable block A61, a movable block B62, a slider A63, a slider B64, and an adjustment shaft 65.

Ball blocks B612 are movably provided on both the forward thread groove 69 and the reverse thread groove 610. The two ball blocks B612 are respectively fixedly connected to the slider A63 and the slider B64. With the above settings in the present invention, when the knob B66 is rotated, the adjustment shaft 65 rotates, causing the two ball blocks B612 to move on the forward thread groove 69 and the reverse thread groove 610 respectively. As a result, the slider A63 and the slider B64 slide towards each other in the sliding groove 14. The slider A63 drives the movable block A61 to move in the sliding cavity 13 through the connecting rod 67, and the slider B64 drives the movable block B62 to move in the sliding cavity 13 through the telescopic rod 68. The opposing movement of the movable block A61 and the movable block B62 causes the movable column A52 to move in the straight groove A11 and the movable column B53 to move in the displacement guide groove 12. When the movable column B53 moves in the arc groove B121 of the displacement guide groove 12, the telescopic rod 68 adaptsively expands and contracts.

[0030] In an embodiment of the present invention, the pitch of the forward thread groove 69 is smaller than the pitch of the reverse thread groove 610, and arc grooves C611 are communicated and provided at the far ends of the forward thread groove 69 and the reverse thread groove 610. Through the further design of the forward thread groove 69 and the reverse thread groove 610 in the present invention, the moving distance of the slider A63 is greater than the moving distance of the slider B64, so that the moving distance of the adsorption unit 56 adsorbed on the upper eyelid is greater than the moving distance of the adsorption unit 56 adsorbed on the lower eyelid. Among them, the adsorption position of the adsorption unit 56 adsorbed on the upper eyelid is close to the eyelash part, and the specific adsorption position of the adsorption unit 56 adsorbed on the lower eyelid is the skin close to the cheek. The arc grooves C611 are provided to limit the ball blocks B612 and prevent the blinking action when the patient's eyes are opened.

[0031] In an embodiment of the present invention, the metering mechanism 3 includes a liquid storage bottle 31. The liquid storage bottle 31 has a tapered structure with a larger upper part and a smaller lower part. The liquid storage bottle 31 is fixedly arranged on the installation groove 18.

The other end of the connecting shaft 37 penetrates out of the eye mask 1 and is fixedly provided with an adjusting round block 38. An indicating groove A39 is formed on the adjusting round block 38 at positions corresponding to the two quantitative grooves 36. An indicating groove B111 is formed on the eye mask 1 at a position corresponding to the indicating groove A39. Through the above settings of the present invention, every time the adjusting round block 38 is rotated half a turn, a unit volume of eye drops is transported from the liquid storage bottle 31 through the quantitative groove 36 to the lower pipeline 30 and drops down. Among them, the indicating groove A39 and the indicating groove B111 are provided to assist the metering operation.

[0032] In an embodiment of the present invention, the eye-dropping mechanism 4 includes a dropper 41 and a rotating rod 43. The dropper 41 is fixedly arranged on the fixing plate 15. The top end of the dropper 41 penetrates into the rotating cavity 16 and is communicated with a rubber head 42.

The clamping blocks 44 are movably connected with the rubber head 42. The clamping blocks 44 are adapted to the shape of the eye mask 1. The clamping blocks 44 are slidably connected with the arc groove A17 through movable arc blocks 45. The two movable arc blocks 45 are elastically connected through an arc spring 46. Through the structural settings of the eye-dropping mechanism 4 of the present invention, when a patient presses the two clamping blocks 44, the two movable arc blocks 45 move inside the arc groove A17, and the arc spring 46 shortens. The two clamping blocks 44 rotate relative to the rotating rod 43 and form extrusion on the rubber head 42, so that the eye drops in the rubber head 42 fall along the dropper 41. Among them, the dropper 41 is fixedly arranged on the fixing plate 15 at the gap position between the two movable columns B53 when the relative distance to the movable column A52 is the closest. Since the adsorption position of the adsorption unit 56 adsorbed on the upper eyelid is close to the eyelash part, that is, arranged according to the best position when referring to dropping eye drops. After the eye drops are completed, the patient releases the finger. Under the elastic force of the arc spring 46, the two movable arc blocks 45 and the two clamping blocks 44 are reset, and this structure is more labor-saving compared with the traditional way of directly pressing the eye drop bottle (especially the difficult-to-press eye drop bottle).
