Description

Technical Field

[0001] This utility model relates to the field of demonstration tools, and in particular to an ophthalmology education tool. Background Technology

[0002] Currently, in clinical practice, educating patients on the correct use of eye drops relies solely on pictures or videos, or by demonstrating the procedure directly. Pictures are too abstract and difficult to understand, especially for elderly ophthalmology patients. Videos are more visual and concrete, but offer no opportunity for hands-on practice. While directly administering eye drops is intuitive, the frequency of daily eye drops use is limited, making it impractical to demonstrate the procedure anytime, anywhere. There is an urgent need for an educational tool that allows for direct demonstrations of eye drop administration to patients, while also providing opportunities for them to practice and for healthcare professionals to correct any errors. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an ophthalmological education tool, which aims to solve the problem in the prior art that patients have difficulty understanding the educational content and have no opportunity to practice when being educated on the correct use of eye drops.

[0004] This utility model provides an ophthalmological education tool, including an eye structure, a support, and a dropper. The eye structure includes an outer frame and an eyeball. The outer frame is rotatably connected to the support. The outer frame has a hollow structure with an opening. The eyeball is rotatably housed within the outer frame. The eyeball has a first pupil area and a second pupil area spaced apart. The second pupil area is located above the first pupil area. The first pupil area is located on a horizontal plane, and the second pupil area forms an angle with the horizontal plane. The outer frame is used to rotate so that the opening corresponds to either the first pupil area or the second pupil area. The dropper is used to hover above the eyeball when the opening corresponds to the second pupil area. A sensor is provided inside the eyeball to receive signals from the dropper.

[0005] According to some embodiments of the present invention, a rotating shaft is provided on the outer periphery of the eyeball, and the rotating shaft is connected to the outer frame through a bearing.

[0006] According to some embodiments of the present invention, the central axis of the rotating shaft is located above the center of gravity of the eyeball so that when the outer frame rotates relative to the eyeball, the first pupil region remains parallel to the horizontal plane.

[0007] According to some embodiments of the present invention, the upper half of the eyeball is a hollow structure, and the lower half of the eyeball is a solid structure.

[0008] According to some embodiments of the present invention, the bracket includes a support rod and a base, one end of the support rod is vertically connected to the base, and the other end is rotatably connected to the outer frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides an ophthalmological education tool, including an eye structure 1, a support 2, and a dropper 3. The eye structure 1 includes an outer frame 11 and an eyeball 12. The outer frame 11 is rotatably connected to the support 2. The outer frame 11 has a hollow structure with an opening 111. The eyeball 12 is rotatably housed within the outer frame 11. The eyeball 12 has a first pupil region 121 and a second pupil region 122 spaced apart. The second pupil region 122 is located above the first pupil region 121. The first pupil region 121 is located on a horizontal plane, and the second pupil region 122 forms an angle with the horizontal plane. The outer frame 11 is used to rotate so that the opening 111 corresponds to the first pupil region 121 or the second pupil region 122. The dropper 3 is used to hover above the eyeball 12 when the opening 111 corresponds to the second pupil region 122. A sensor 125 is provided inside the eyeball 12 to receive signals from the dropper 3.

[0020] Furthermore, the sensor 125 is a photoelectric sensor, and a laser lamp is installed inside the dropper bottle 3. The dropper bottle 3 is equipped with a button 31 for controlling the laser lamp. Specifically, the dropper bottle 3 mimics the shape of an eye drop bottle, and the laser lamp uses low-power visible red light or infrared laser. A photoelectric sensor, which can be a PIN photodiode or a photoresistor, is installed inside the eyeball 12, and must be matched with the laser wavelength inside the dropper bottle 3. Furthermore, a preamplifier, bandpass filter, comparator, calibration mechanism, main control chip, and alarm unit are installed inside the eyeball 12. The preamplifier amplifies the weak photocurrent signal; the bandpass filter filters out stray light of non-modulated frequencies (such as fluorescent lamp interference); and the comparator sets the threshold voltage. When the light intensity is higher than the threshold, a trigger signal is output; the calibration mechanism is used for mechanical fine-tuning knobs or autofocus devices to ensure that the receiver and transmitter are accurately aligned; the main control chip is used to realize logical judgment and delay control, and can programm delay trigger (0.1~10 seconds) to avoid false alarms caused by brief obstruction (such as flying insects); the alarm unit uses a buzzer and LED.

[0021] In practice, when the opening 111 is aligned with the first pupil area 121, the eye is simulated looking straight ahead. When eye drops are needed, the operator rotates the outer frame 11 upwards. Since the eyeball 12 can rotate relative to the outer frame 11, the lower part of the outer frame 11 blocks the first pupil area 121, exposing the second pupil area 122 through the opening 111. This simulates the supine position with the eyeball 12 turned upwards. The operator picks up the dropper bottle 3 and presses button 31 on the dropper bottle 3 to activate the laser light, initiating the eye drops. An alarm will sound if the bottle opening is below 2cm or if the laser beam falls within the second pupil area 122.

[0022] Furthermore, the outer frame 11 is made of skin-like silicone. A suitable pressure sensor is selected based on the functional requirements of the outer frame 11. The pressure sensor is integrated into the silicone to ensure it responds sensitively to external stimuli. The material can be conductive silicone or conductive materials (such as carbon nanotubes, graphite, conductive silver wires, etc.) can be added to the silicone to ensure signal transmission. Specifically, pressure sensors are installed everywhere except below the opening 111 (which simulates the lower eyelid). For example, pulling up the upper eyelid will trigger an alarm, alerting the patient to an operational error. Because the outer frame 11 is made of skin-like silicone, eye drops can be administered by pulling down the lower eyelid.

[0023] According to some embodiments of this utility model, a rotating shaft 123 is provided on the outer periphery of the eyeball 12, and the rotating shaft 123 is connected to the outer frame 11 via a bearing 124. Specifically, the central axis of the rotating shaft 123 is located above the center of gravity of the eyeball 12 so that when the outer frame 11 rotates relative to the eyeball 12, the first pupil region 121 remains parallel to the horizontal plane. This embodiment can ensure that when the outer frame 11 is rotated, the eyeball 12 will not rotate with the outer frame 11, so both the first pupil region 121 and the second pupil region 122 remain in their original positions.

[0024] According to some embodiments of this utility model, the upper half of the eyeball 12 is a hollow structure, and the lower half of the eyeball 12 is a solid structure. This embodiment ensures that the central axis of the rotating shaft 123 is located above the center of gravity of the eyeball 12.

[0025] According to some embodiments of this utility model, the support 2 includes a support rod 21 and a base 22. One end of the support rod 21 is vertically connected to the base 22, and the other end is rotatably connected to the outer frame 11. In this embodiment, the area and weight of the base 22 need to be greater than the eye structure 1 to prevent the entire educational tool from tipping over during the eye drop application process.

[0026] According to some embodiments of this utility model, one end of the support rod 21 is connected to a ball socket 24, and the outer frame 11 is connected to a connecting rod 25 and a ball head 26, with the ball head 26 rotatably connected within the ball socket 24. In this embodiment, due to the cooperation between the ball head 26 and the ball socket 24, when the outer frame 11 is rotated to a suitable position, even if the external force is removed, the outer frame 11 can remain in the suitable position.

[0027] According to some embodiments of this utility model, the ball socket 24 is threadedly connected to an adjusting screw 27, the end of which extends into the interior of the ball socket 24 and abuts against the ball head 26. In this embodiment, the tightness between the ball head 26 and the ball socket 24 can be adjusted by turning the adjusting screw 27, thereby improving the smoothness of rotation.

[0028] According to some embodiments of this utility model, a limiting groove 28 is formed on the ball socket 24, and the limiting groove 28 allows the connecting rod 25 to enter. In this embodiment, the limiting groove 28 is used to limit the rotation direction of the connecting rod 25 to prevent deviation.
