Description

Technical Field

[0001] This invention specifically relates to an eye medication application device. Background Technology

[0002] Ocular medications aim to improve the treatment outcomes of eye diseases and enhance patients' quality of life. Traditional methods of ocular drug delivery mainly include eye drops and ointments. However, these methods have significant limitations. With the rising incidence of eye diseases such as diabetic retinopathy, glaucoma, and dry eye syndrome, the need for efficient, safe, and convenient ocular drug delivery methods is becoming increasingly urgent.

[0003] For example, Chinese patent CN211610322U discloses an ophthalmic medication application aid device. When using this device, the medicine bottle is placed inside the working block, and the medicine bottle outlet is held in place by the action of the first threaded rod and the clamping block to prevent the medicine bottle from deviating during the medication application process. At the same time, in conjunction with the dropper, the medicine dripping from the medicine bottle can be dripped into the patient's eye through the dropper to avoid the situation of deviated dripping and to prevent the medicine from being wasted. At the same time, it can open the eyelid to prevent the medicine from not entering the eyelid due to involuntary blinking during the medication application.

[0004] However, most current eye medication devices are drop-type, which are inconvenient for targeted and controlled application of medication to the affected area of ​​the eye, thus reducing the applicability of traditional eye medication devices. In view of this, an eye medication device is proposed to solve the above-mentioned technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention proposes an ophthalmic medication device to solve the technical problem mentioned in the background art, that most existing ophthalmic medication devices are drop-type, which are inconvenient for localized and controllable medication application to the diseased area of ​​the eyeball, thus reducing the applicability of traditional ophthalmic medication devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an eye medication application device, comprising:

[0007] The mounting frame has a support frame on one side, and the support frame has a mounting groove. The mounting frame has a spray head, the mounting groove has a piston cylinder, and the piston cylinder has a sliding piston plate.

[0008] An indicator component, disposed within the mounting frame, is provided to provide directional guidance for the eyeball;

[0009] A medicine storage bottle is mounted on the mounting frame and connected to the spray head and the piston cylinder via a medicine supply assembly. The medicine supply assembly converts the reciprocating sliding of the piston plate into supplying the medicine liquid in the medicine storage bottle to the spray head.

[0010] A button, height-adjustable, is mounted on the support frame and connected to the piston plate via a drive mechanism. The drive mechanism converts the movement of the button into the sliding motion of the piston plate.

[0011] An adjustment mechanism is provided on the support frame and connected to the drive mechanism to adjust the distance the piston plate slides when the button is pressed once.

[0012] Furthermore, the indicating component includes:

[0013] A separator frame, disposed within the mounting frame, divides the mounting frame into multiple indicating areas along the circumferential direction; the spray head is disposed in the middle of the separator frame; and

[0014] The baffle is made of transparent material, and each indicator area is provided with an indicator point on the baffle.

[0015] Furthermore, the drug delivery assembly includes:

[0016] An installation sleeve is provided on the support frame, and the medicine storage bottle is detachably installed in and communicates with the installation sleeve;

[0017] An air supply pipe, one end of which is connected to the piston cylinder, and the other end of which is connected to the mounting sleeve via an outlet check valve, extends into the medicine storage bottle; the piston cylinder is equipped with an inlet check valve; and

[0018] The drug supply tube is connected at one end to the mounting sleeve and at the other end to the spray head.

[0019] Furthermore, the drive mechanism includes:

[0020] A drive rod is disposed on the button, and a first elastic element is disposed between the drive rod and the mounting groove; a drive post is disposed at the end of the drive rod.

[0021] A sliding frame, one end of which is hinged to the mounting slot, a drive column slidably disposed within the sliding frame, and a push rod mounted on the sliding frame via a rocker arm; and

[0022] The drive arm is hinged at one end to the push rod, and a piston rod is provided on the piston plate. The other end of the drive arm is hinged to the piston rod.

[0023] Furthermore, the adjustment mechanism includes:

[0024] The mounting shaft is rotatably and slidably mounted on the mounting groove along its axis, and its axis coincides with the hinge point of the slide frame. The rocker arm is fixedly mounted on the mounting shaft.

[0025] A locking assembly, disposed on the mounting shaft and connected to the slide frame, allows for selective locking or unlocking of the position of the rocker arm and the slide frame as the mounting shaft slides; and

[0026] A knob is located at the end of the mounting shaft.

[0027] Furthermore, the locking component includes:

[0028] The first toothed disc is disposed at the end of the slide frame;

[0029] The second gear is disposed on the mounting shaft and meshes with the first gear;

[0030] A baffle is disposed on one side of the mounting slot; and

[0031] The second elastic element is disposed between the second toothed disc and the baffle.

[0032] Furthermore, the push rod is slidably disposed at the end of the drive arm along its axis.

[0033] Furthermore, the knob is provided with two sets of relatively slidable buttons, which are connected to the baffle through a push assembly. The push assembly converts the sliding of the buttons into driving the sliding of the mounting shaft.

[0038] Furthermore, a scale line is arranged circumferentially on one side of the baffle, and an indicator arrow is provided on the knob.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The device is worn on the head, with a support frame positioned over the ear to move the mounting frame to the side of the eye. Adjusting the support frame positions the spray nozzle along the midline of the eyeball. Pressing the button activates a piston plate via a drive mechanism. This piston plate, through a dispensing assembly, supplies the medication from the reservoir to the spray nozzle, which then delivers the medication to the eyeball. During application, an indicator component directs the eye to a specific location for targeted medication application, avoiding the obstruction of the eyelid by traditional drop methods. This also helps divert attention and prevents eye closure due to stress, thus avoiding medication waste. Furthermore, an adjustment mechanism allows for adjustment of the piston plate's sliding distance with each button press, thus regulating the medication dosage to suit different patients.

[0059] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0060] Example:

[0061] like Figures 1 to 5 As shown, the present invention provides an eye medication application device, including a mounting frame 1, a support frame 11 on one side of the mounting frame 1, an installation groove 15 inside the support frame 11, and a spray head 14 inside the mounting frame 1. An indicator component is provided inside the mounting frame 1 to provide directional guidance for the eyeball. The indicator component includes a partition frame 16 and a baffle 12 disposed within the mounting frame 1. The partition frame 16 divides the mounting frame 1 into multiple indicator areas along the circumference. The spray head 14 is disposed in the middle of the partition frame 16. The baffle 12 is made of transparent material, and an indicator point 13 is provided on the baffle 12 corresponding to each indicator area.

[0062] When in use, the device can be worn by wearing glasses, with the support frame 11 placed on the patient's ear. By adjusting the position of the support frame 11, the spray head 14 is aligned with the center of the eye. The spray head 14 can spray out the medication. During the application of the medication, the patient can control the eyeball to look in the opposite direction to the indicator point 13, so as to expose the affected area and divert the eye's attention. This avoids the eyelids closing due to stress during the application of the medication, thus achieving the purpose of precise application of medication to the local area of ​​the eyeball.

[0063] like Figures 3 to 5 As shown, in this embodiment, a piston cylinder 25 is provided in the mounting groove 15, and a slidable piston plate 41 is provided inside the piston cylinder 25. A medicine storage bottle 21 is provided on the mounting frame 1. The medicine storage bottle 21 is connected to the spray head 14 and the piston cylinder 25 through a medicine supply assembly. The medicine supply assembly converts the reciprocating sliding of the piston plate 41 into supplying the medicine liquid in the medicine storage bottle 21 to the spray head 14. The medicine supply assembly includes a mounting sleeve 2 provided on the support frame 11. One end of the air supply pipe 24 is connected to the piston cylinder 25, and the other end is connected to the mounting sleeve 2 through an air outlet check valve 23 and extends into the medicine storage bottle 21. An air inlet check valve 26 is provided on the piston cylinder 25. One end of the medicine supply pipe 22 is connected to the mounting sleeve 2, and the other end is connected to the spray head 14.

[0064] During the reciprocating sliding process of the piston plate 41, outside air can be introduced into the air supply pipe 24 through the inlet one-way valve 26, and air can be supplied into the medicine storage bottle 21 through the outlet one-way valve 23. The air pressure then forces the medicine in the medicine storage bottle 21 into the medicine supply pipe 22, and sprays it out through the spray head 14, achieving the purpose of applying the medicine. Additionally, it is understood that in some embodiments, a filter screen can be installed on the inlet one-way valve 26 to prevent outside air from entering the medicine storage bottle 21 and contaminating the medicine.

[0065] like Figure 3 , 5 As shown in Figures 6 and 7, in this embodiment, a button 3 is vertically detachable on the support frame 11. The button 3 is connected to the piston plate 41 via a drive mechanism, which converts the movement of the button 3 into the sliding of the piston plate 41. The drive mechanism includes a drive rod 32 mounted on the button 3, a first elastic element 31 between the drive rod 32 and the mounting groove 15, a drive column 33 at the end of the drive rod 32, a hinged sliding frame 51 on the mounting groove 15, the drive column 33 slidably mounted within the sliding frame 51, a push rod 63 mounted on the sliding frame 51 via a rocker arm 62, a drive arm 42 hinged to the end of the push rod 63, a piston rod 4 on the piston plate 41, and the other end of the drive arm 42 hinged to the piston rod 4.

[0066] After being pressed, button 3 can be reset by the first elastic element 31. During the movement of button 3, the drive rod 32 and the drive column 33 at its end move. During the movement of the drive column 33, the slide frame 51 can be rotated along the hinge point between the slide frame 51 and the mounting groove 15 through the cooperation of the drive rod 63 and the drive arm 42, so that the rocker arm 62 swings. During the swing of the rocker arm 62, the piston rod 4 moves through the cooperation of the push rod 63 and the drive arm 42, so that the piston plate 41 reciprocates in the piston cylinder 25. Each press of one side of button 3 can realize a single supply of medicine without manually squeezing the medicine bottle, so that the amount of medicine supplied each time is constant.

[0067] like Figure 3 , 5 As shown in Figures 6 and 7, in this embodiment, the support frame 11 is provided with an adjustment mechanism connected to the drive mechanism. The adjustment mechanism adjusts the sliding distance of the piston plate 41 when the button 3 is pressed once. The adjustment mechanism includes a mounting shaft 6 that is rotatable and slidable along its axis and is provided on the mounting groove 15. The axis of the mounting shaft 6 coincides with the hinge point of the slide frame 51. The rocker arm 62 is fixedly provided on the mounting shaft 6. The mounting shaft 6 is provided with a locking component connected to the slide frame 51. The locking component can selectively lock or unlock the position of the rocker arm 62 and the slide frame 51 when the mounting shaft 6 slides. The locking component includes a first gear 5 provided at the end of the slide frame 51 and a second gear 61 provided on the mounting shaft 6. The second gear 61 meshes with the first gear 5. A baffle 8 is provided on one side of the mounting groove 15. A second elastic element 64 is provided between the second gear 61 and the baffle 8. A knob 7 is provided at the end of the mounting shaft 6.

[0068] Pulling the knob 7 causes the mounting shaft 6 to slide along its axis. During this sliding process, the second gear 61 disengages from the first gear 5, thus releasing the position lock of the rocker arm 62. Rotating the knob 7 then rotates the rocker arm 62. Once the rocker arm 62 reaches the desired position, releasing the knob 7 allows the mounting shaft 6 to reset under the action of the second elastic element 64, and the second gear 61 to re-engage on the first gear 5, completing the position lock of the rocker arm 62. The angle between the rocker arm 62 and the sliding frame 51 changes, and the horizontal movement distance of the rocker arm 62 changes when the sliding frame 51 rotates by the same angle. Therefore, the movement distance of the piston plate 41 each time the button 3 is pressed can be determined using trigonometric functions. A scale line 81 is arranged circumferentially on one side of the baffle 8, and an indicator arrow 74 is provided on the knob 7. The scale line 81 is marked according to the calculation results to precisely adjust the amount of liquid supplied each time the button 3 is pressed. The push rod 63 is slidably disposed at the end of the drive arm 42 along its axis, so that the push rod 63 remains hinged to the drive arm 42 during the sliding process of the mounting shaft 6.

[0069] like Figures 6 to 8As shown, in this embodiment, the knob 7 is provided with two sets of relatively slidable buttons 71. The buttons 71 are connected to the baffle 8 through a push assembly, which converts the sliding of the buttons 71 into the sliding of the mounting shaft 6. The push assembly includes a third elastic element 73 disposed between the two sets of buttons 71. Each set of buttons 71 is fixedly provided with a push block 72, which extends out of one side of the knob 7. The end of the push block 72 is provided with a slope, and one side of the baffle 8 is provided with an annular boss 82. After the push block 72 slides, its slope can abut against the annular boss 82.

[0070] When operating knob 7, the third elastic element 73 can be compressed by pressing the two sets of push blocks 71. During the sliding process of push block 71, push block 72 moves along with it. During the movement of push block 72, the knob 7 slides along its axis through the contact between its inclined surface and the annular boss 82, so that the mounting shaft 6 can slide. Then turn knob 7. The locking component can be controlled without pulling knob 7 separately, which improves the convenience of using the device.

[0071] Specific usage and beneficial effects of the present invention:

[0072] The device is worn on the head during use. A support frame 11 is placed over the ear, allowing the mounting frame 1 to move to the side of the eye. The position of the support frame 11 is adjusted so that the spray head 14 is positioned on the midline of the eyeball. Pressing button 3 then moves the piston plate 41 via a drive mechanism. During this movement, the piston plate 41 supplies the medication from the storage bottle 21 to the spray head 14, which sprays the medication onto the eyeball. During medication application, an indicator component directs the eyeball to a designated location for easy localized application, avoiding the problem of the eyelid obstructing the application of medication as with traditional drop methods. This also helps to divert attention and prevents the eye from closing due to stress, thus avoiding medication waste. Furthermore, the distance the piston plate 41 slides with each press of button 3 can be adjusted via an adjustment mechanism to regulate the amount of medication applied, adapting to different patients.

[0073] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art.
