Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an accurate and safe medication dispensing aid for ophthalmic bottled eye drops. Background Art

[0002] Ophthalmic diseases are one of the most common diseases in the world. With the aging of the population and the intensification of environmental pollution, the incidence of ophthalmic diseases has increased year by year. Ophthalmic diseases cover a wide range of types, from mild eye discomfort to severe visual impairment, and may even lead to blindness. With the increasing number of ophthalmic diseases, eye drops, as a very common and effective treatment method, have been widely used in the treatment of various types of ophthalmic diseases.

[0003] However, the traditional eye drop bottle mouth does not have a mechanism to control the drop distance, and patients often find it difficult to grasp the exact drop position when using it. If the bottle mouth is too close, it is easy to poke the eyeball or cause eye discomfort; if the bottle mouth is too far, the eye drops may not enter the eyes, wasting the medicine or causing poor treatment effect. In addition, many patients have unstable hands, difficulty opening their eyes or lack of auxiliary support when dropping the medicine, which leads to the inability to accurately control the timing and amount of the medicine during the drop process, thereby reducing the treatment effect. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide an accurate and safe medication aid for ophthalmic bottled eye drops, aiming to solve the technical problems existing in the prior art mentioned in the background technology.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0033] like Figure 1 - Figure 3 As shown, in one embodiment, a precise and safe medication dispensing aid for ophthalmic bottled eye drops is provided, comprising:

[0034] The eye support mechanism 1 is provided with an eyelid opening component 11 with adjustable opening and closing angles and a protective contact component 12 in contact with the skin around the eye;

[0035] The eyelid opening assembly 11 includes an upper eyelid support arm 111 and a lower eyelid support arm 112. The upper eyelid support arm 111 and the lower eyelid support arm 112 are cross-arranged to form a scissor opening and closing structure, and a damping bearing 113 is arranged at the cross-section;

[0036] The protective contact assembly 12 includes two groups of symmetrically arranged arc-shaped support bars 121, and the ends of the two groups of arc-shaped support bars 121 are respectively connected to the upper eyelid support arm 111 and the lower eyelid support arm 112;

[0037] A medicine bottle clamping mechanism 2, connected to the eye support mechanism 1, for stably clamping and fixing the eye drop bottle 6;

[0038] The drop observation mechanism 3 is arranged on the side of the medicine bottle clamping mechanism 2, and is used to observe and confirm the exact position and dripping condition of the drop, so as to ensure that the medicine can be accurately dropped on the surface of the eyeball;

[0039] The eye support mechanism 1, the medicine bottle clamping mechanism 2 and the dripping observation mechanism 3 form a spatial linkage and coordination to achieve the synergistic effect of maintaining the eyelid opening, accurately positioning the medicine bottle and visualizing the dripping process.

[0040] In actual application of this embodiment, during operation, the user drives the eye support mechanism 1 to fit the patient's eyes with one hand, and adjusts the opening and closing angle of the eyelid opening component 11 until the upper eyelid support arm 111 and the lower eyelid support arm 112 of the eyelid opening component 11 respectively drive the protective contact component 12 to fit the patient's upper eyelid and lower eyelid, and fixes the opening and closing angle of the eyelid opening component 11 through the damping bearing 113. At this time, while keeping the eyelids in an open state, it is prevented that the eyelid opening component 11 causes damage to the patient's skin around the eyes when opening the eyelids. At the same time, the eye drop bottle 6 is clamped by the medicine bottle clamping mechanism 2, and the dripping of the eye drop bottle 6 is observed by the dripping observation mechanism 3 to ensure that the drops can fall accurately on the surface of the eyeball. During use, due to the spatial linkage formed between the eye support mechanism 1, the medicine bottle clamping mechanism 2 and the dripping observation mechanism 3, they can work together to maintain the eyelid opening, accurately position the medicine bottle, and visualize the dripping process, which greatly improves the accuracy and safety of medication.

[0041] In this embodiment, the opening force is evenly distributed around the eyes through the arc-shaped support bar 121 to avoid skin compression. The upper eyelid support arm 111 and the lower eyelid support arm 112 of the scissors opening and closing structure can achieve adjustable resistance opening and closing through the damping bearing 113.

[0042] In one case of this embodiment, the eye support mechanism 1, the medicine bottle clamping mechanism 2 and the liquid drop observation mechanism 3 are realized through spatial linkage: a stable operating space is formed after the eyelids are opened - the medicine bottle is accurately positioned to the conjunctival sac projection area - mirror reflection displays the liquid drop position in real time.

[0043] See also Figure 4 As a preferred embodiment of the present invention, the eyelid stretching assembly 11 also includes a finger ring 114, which is fixedly connected to the other end of the upper eyelid supporting arm 111 and the lower eyelid supporting arm 112, and a protective rib 115 is provided on the opposite side of the two finger rings 114.

[0044] In actual application of this embodiment, the protective ribs 115 of the finger ring 114 form a fulcrum for transmitting operating force. During operation, the index finger and the thumb are respectively inserted into the finger rings 114 on both sides, which is convenient for medical staff to operate with one hand. The protective ribs 115 limit excessive inward retraction of the fingers. The opening and closing angles of the finger ring 114 and the movement trajectories of the upper eyelid support arm 111 and the lower eyelid support arm 112 form a lever transmission. Through the opening and closing action of the finger ring 114, the opening and closing angles of the eyelid opening assembly 11 can be easily adjusted, so that the upper eyelid support arm 111 and the lower eyelid support arm 112 can fit the eyelid shapes of different patients, further improving the comfort and adaptability of use.

[0045] See also Figure 4 As another preferred embodiment of the present invention, an auxiliary spring 4 is arranged between the upper eyelid supporting arm 111 and the lower eyelid supporting arm 112, and both ends of the auxiliary spring 4 are respectively connected to the upper eyelid supporting arm 111 and the lower eyelid supporting arm 112.

[0046] In this embodiment, when the opening angle between the upper eyelid support arm 111 and the lower eyelid support arm 112 is greater than a specified angle, the auxiliary spring 4 generates a reverse force to prevent excessive opening, and a dynamic balance relationship is formed between the auxiliary spring 4 and the damping bearing 113.

[0047] See also Figure 5 As another preferred embodiment of the present invention, the protective contact component 12 also includes a protective silicone pad layer 122, which is fixed to the arc-shaped support bar 121, and a plurality of anti-slip protrusions 123 are arranged on the contact surface between the protective silicone pad layer 122 and the skin.

[0048] In this embodiment, a micro-adsorption effect is generated between the anti-slip bumps 123 and the user's eye skin, thereby enhancing the stability of the device. The hardness value of the protective silicone pad layer 122 is adapted to the eye skin, ensuring that it will not cause pressure or discomfort even after long-term use. In addition, the material of the protective silicone pad layer 122 is breathable and skin-friendly, which can effectively reduce the friction between the eye skin and the auxiliary device, further improving the comfort and safety of use.

[0049] In one aspect of this embodiment, the radius of curvature of the arc-shaped support bar 121 matches the anatomical structure of the eye socket of Asians.

[0050] See also Figure 6 As another preferred embodiment of the present invention, the medicine bottle clamping mechanism 2 includes an elastic clamping claw 21, which is hinged on the eyelid opening component 11 and has a built-in pressure feedback module. A tension spring 22 is connected to the elastic clamping claw 21, and a fastener 23 is nested on the inner wall of the elastic clamping claw 21.

[0051] In this embodiment, the elastic clamping claw 21 generates an adaptive clamping force through the tension spring 22, the inclined extrusion block 232 of the fastener 23 forms a three-point contact fixation with the bottle body, and the pressure feedback module monitors the clamping force in real time.

[0052] See also Figure 7 As another preferred embodiment of the present invention, the fastener 23 includes a flexible pad 231 bonded to the inner wall of the elastic clamp 21, and a plurality of inclined extrusion blocks 232 are connected to the edge of the flexible pad 231, and the extrusion blocks 232 are in contact with the bottle body of the eye drop bottle 6.

[0053] In this embodiment, the squeezing block 232 contacts the body of the eye drop bottle 6 at an inclined angle of 15°, converting the axial clamping force into a radial squeezing force to improve the clamping stability. The flexible pad 231 is made of silicone material to improve the buffering performance during clamping and avoid clamping the bottle body.

[0054] See also Figure 8 As another preferred embodiment of the present invention, the drop observation mechanism 3 includes a limit cylinder 31, a limit rod 32, a rotating arm 33 and a mirror plate 34. The limit cylinder 31 is fixedly connected to the end of any one of the arc-shaped support strips 121, the limit rod 32 is fixedly connected to the end of another arc-shaped support strip 121, and is slidably fitted in the limit cylinder 31. A rotating arm 33 is provided at the outer wall of the limit cylinder 31 through a bearing sleeve, and the mirror plate 34 is fixedly connected to the rotating arm 33.

[0055] In this embodiment, the mirror plate 34 can be adjusted at multiple angles through the rotating arm 33. The sliding cooperation of the limit rod 32 in the limit tube 31 ensures that the observation mirror and the medicine bottle remain coaxially positioned, and when the eye support mechanism 1 is opened and closed, the limit rod 32 slides synchronously in the limit tube 31 to ensure the stability and accuracy of the drop observation mechanism 3.

[0056] See also Figure 8 As another preferred embodiment of the present invention, a fill light 5 is fixedly connected to the mirror plate 34 .

[0057] In this embodiment, the fill light 5 provides dripping track illumination and cooperates with the drip observation mechanism 3, so that medical staff can clearly observe the dripping situation of the eye drop bottle 6, thereby ensuring that the eye drops can be accurately and safely injected into the conjunctival sac each time, reducing the patient's pain and discomfort.
