Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an eyelid-opening eye drop device. Background Technology

[0002] The traditional method for administering eye drops is to lie flat or tilt your head back slightly, use two fingers of one hand to open the eyelid, and hold the eye drop bottle 1.5 to 2 centimeters away from the eyeball with the other hand, gently squeezing the bottle to drop the solution into the conjunctival sac below the eyeball. However, many children, the elderly, or ophthalmology patients find this difficult to perform. They may struggle to simultaneously open the lower eyelid, control the distance between the eye drop bottle and the eyeball, and squeeze out the solution, making it easy for the bottle tip to come into contact with the cornea or other parts of the eye, causing contamination of the eye drop solution or even scratching the cornea or other eye tissues. Furthermore, instilling a single drop can obstruct vision, increasing the difficulty of subsequent drops. Also, the eyelids may blink reflexively just before the drop enters the eye, requiring the fingers to work in tandem, making it difficult to maintain an open eyelid. Existing technologies such as CN211356208U and CN217118732U all use some supporting rods to open the eyelids. Existing devices cannot open the eyelids, but only keep the eyelids open. They are inconvenient to operate, and these structures all have sharp rod-like structures, which pose a significant safety hazard to children or the elderly when using them. Summary of the Invention

[0018] Furthermore, the distance between the first and / or second eyelid spheres can be adjusted along the first and / or second axes.

[0019] Furthermore, the angle between the first axis and the second axis is adjustable.

[0020] As an alternative to the eyelid-opening eye drop device, the applicator is an atomizer.

[0021] Furthermore, the atomizer includes an atomizing chamber, a nozzle, and a pneumatic assembly.

[0022] Furthermore, the main body also includes an air inlet.

[0023] As an optional solution for the eyelid-opening eye drop device, a battery is provided inside the receiving cavity.

[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] This embodiment provides an experimental apparatus for an animal model of an ophthalmic disease, which is described below in conjunction with... Figures 1 to 7 The specific content of this embodiment will be described in detail.

[0047] In this embodiment, the present invention provides an eyelid-opening eye drop device, including an eyelid-separating assembly 10, a main body 20, a drug applicator 30, and a control assembly 40; the main body 20 includes a back shell 205 and a cover 203, which are assembled to form a receiving cavity 206, and the drug applicator 30 is disposed in the receiving cavity 206; the eyelid-separating assembly 10 is disposed at one end of the main body 20, and includes a first eyelid-separating ball 102 and a second eyelid-separating ball 104, which are connected to the main body 20 via a first axis 101 and a second axis 103, respectively. The first eyelid-separating ball 102 can rotate around the first axis 101, and the second eyelid-separating ball 104 can rotate around the second axis 103; the drug applicator 30 includes an eye drop cavity 301 and a drug application nozzle 302, which is disposed at the same end of the main body 20 and the eyelid-separating assembly 10; the control assembly 40 is configured to trigger the drug applicator 30 to release the drug solution from the drug application nozzle 302.

[0048] In another alternative embodiment, the body 20 is rod-shaped and has a first end and / or a second end.

[0049] In another alternative embodiment, the main body 20 includes a main body head 201 and a main body handle 202, and the eyelid separation assembly 10 is disposed on the main body head 201.

[0050] In another alternative embodiment, at least a portion of the first eyelid sphere 102 and / or the second eyelid sphere 104 is provided with friction textures 105.

[0051] Furthermore, friction marks can be raised or recessed in the form of dots, stripes, or wavy lines.

[0052] Furthermore, the friction texture can be formed on soft materials such as wood, silicone, and rubber. The friction texture increases the coefficient of friction between the eyelid and the eyeball, reducing the minimum pressure required from the user.

[0053] In another alternative embodiment, the control component 40 includes a trigger switch 401 disposed at the junction of the main body head 201 and the main body handle 202. This position is conveniently located opposite the thumb position during use.

[0054] In another alternative embodiment, the applicator 30 is a drip tube.

[0055] In this embodiment, the trigger switch of the control component 40 can be configured as a physical push rod that squeezes the dropper tubing when the user presses the trigger switch, thereby dispensing eye drops.

[0056] refer to Figure 3 In another optional embodiment, the angle α between the first axis 101 and / or the second axis 103 and the axis of the main body head 201 away from the main body handle 202 or the extension direction of the applicator nozzle is between 10 degrees and 80 degrees. Further, the angle α between the first axis 101 and / or the second axis 103 and the axis of the main body head 201 away from the main body handle 202 is between 30 degrees and 60 degrees.

[0057] The angle α between the eyelid splitting axis and the main body of the eyelid splitting component results in the tilt relationship between the eyelid splitting ball and the main body, thereby further causing the rotation direction of the two eyelid splitting balls to form angles with the eyelids respectively.

[0058] refer to Figure 4 In another optional embodiment, the included angle θ between the first axis 101 and the second axis 103 is between 80 degrees and 150 degrees, and more preferably between 100 degrees and 130 degrees.

[0059] Furthermore, the first axis 101 and the second axis 103 are telescopic rods or sleeve structures, which allows the distance between the first eyelid ball 102 and / or the second eyelid ball 104 to be adjusted along the direction of the first axis 101 and / or the second axis 103.

[0060] Furthermore, the first axis 101 and the second axis 103 are connected to the main body by hinges, which allows the included angle between the first axis 101 and the second axis 103 to be adjustable.

[0061] refer to Figure 5 This diagram illustrates the user's perspective when using the eyelid-opening eye drop device. In the diagram, 60a and 60b represent contact areas a and b between the eyelid-opening bulb and the eyelid, respectively. During use, the two eyelid-opening bulbs are placed against the upper and lower eyelids, respectively. This ensures that there is no relative displacement between the contact areas of the bulbs and the eyelids, allowing operation whether the eyes are open or closed. The user then moves the handle of the eyelid-opening eye drop device along direction A. At this time, the two eyelid-opening bulbs rotate around their respective axes under the influence of friction. Because there is no relative displacement between the contact areas of the bulbs and the eyelids, contact areas 60a and 60b move along their respective tangential directions, directions B and C. Simultaneously, the eyelids also move along directions B and C under the influence of friction, i.e., the eyelids move in the opening direction, thus separating the eyelids. The application nozzle 302 is then positioned directly in front of the eye, allowing for medication application. The application can be either dripping or spraying, depending on the drug form and application mechanism.

[0062] As an alternative to the eyelid-opening eye drop device, the applicator 30 is an atomizer 31.

[0063] Furthermore, the atomizer 31 includes an atomizing chamber 311, a nozzle 312, and a pneumatic assembly.

[0064] Furthermore, the main body 20 also includes an air inlet 204 to ensure continuous air circulation within the device after the pneumatic component blows the atomized liquid out of the nozzle. The pneumatic component can be selected from a miniature gas compressor or a miniature fan.

[0065] The atomizer 31 uses various atomization methods, including electronic atomization, ultrasonic atomization, compression atomization, and micro-mesh atomization.

[0066] In another alternative to the eyelid-opening eye drop device, the applicator 30 is a drop bottle that can dispense medication by squeezing the medication or triggering the opening of the dispensing port.

[0067] In another alternative embodiment, such as Figure 4 As shown, the control component 40 includes an image acquisition unit 402 and a processing module 403. The image acquisition unit 402 is located on the same side as the application nozzle 302, and the processing module 403 is located within the receiving cavity 206. The image acquisition unit acquires images and, when it detects that the eyelids are separated and the application nozzle is directly facing the pupil, sends a signal to trigger the application of medication into the eye. This trigger signal can be a tactile vibration to alert the user to manually trigger the device by pressing a switch on the handle, or an electrical signal to the processing unit to activate the pneumatic components for automatic triggering.

[0068] In another alternative embodiment, a battery is disposed within the accommodating cavity 206.

[0069] In another optional embodiment, the eyelid separating assembly 10 further includes a micro motor, which can drive the first eyelid separating ball 102 and / or the second eyelid separating ball 101 to rotate or vibrate, thereby achieving a certain massage or relaxation effect.

[0070] The second objective of this invention is to provide a control method for an eyelid-opening eye drop device, comprising the following steps:

[0071] S: When the eyelid opening component opens the eyelid and the applicator nozzle is aimed at the preset area of ​​the eyeball, the applicator releases a preset dose of eye drops.

[0072] In another embodiment, the method for controlling the eyelid-opening eye drop device includes the following steps:

[0073] S1: Acquire and process the image data acquired by the image acquisition device 402;

[0074] S2: When it is detected that the eyelid opening component opens the eyelid and the medication application nozzle is aimed at the preset area of ​​the eyeball, a trigger signal is given;

[0075] S3: Upon receiving a trigger signal, the control component 40 controls the applicator to release a preset dose of eye drops.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
