Description

Technical Field

[0001] The utility model relates to the technical field of eye position inspection, in particular to a portable device for photographing children's eye positions. Background Art

[0002] Due to limitations in cognitive, language, and psychological development during their growth and development, children's ability to cooperate with disease diagnosis, treatment, and communication and comprehension is often lower than that of adults. This problem is particularly prominent during eye alignment examinations in children, manifesting as a lack of or minimal cooperation. This lack of cooperation increases the difficulty for doctors in diagnosing illnesses and can easily cause anxiety in parents. For example, parents may doubt the accuracy of a doctor's diagnosis due to their child's lack of cooperation, or, anxious to understand the underlying condition, they may demand "diagnostic evidence" of eye alignment abnormalities.

[0003] Therefore, when pediatric ophthalmologists diagnose eye position, they need to add the function of attracting the patient's attention and photographing the eye position on the basis of routine eye position examination, so as to facilitate subsequent disease diagnosis and eye position interpretation.

[0004] However, the simultaneous operations of attracting the child, photographing the eye position, and moving the penlight require the collaboration of at least two doctors. One doctor is responsible for attracting the child's attention and getting them to look in the direction of the penlight, while the other doctor holds the penlight in one hand and the camera in the other to photograph the eye position. While this operation has high accuracy and a high success rate, it is inefficient and requires at least two doctors. Currently, the eye position examination equipment on the market is mainly ophthalmic penlights, which cannot enable doctors to independently and efficiently complete the eye position examination and photography operations.

[0005] Therefore, there is an urgent need for a device that can add attention-attracting and shooting functions on the basis of routine eye position examination to help doctors complete the examination independently and improve efficiency and accuracy. Utility Model Content

The lower end of the connecting rod 4 is provided with a second rotating mechanism for adjusting the included angle between the connecting rod 4 and the photographing device, facilitating the doctor to observe and photograph the eye position through the screen of the photographing device.

[0033] By setting the photographing device fixing member 7 to fix the photographing device and connecting the commonly used ophthalmic pen lamp fixed on the lamp fixing member 1 through the connecting rod 4, the doctor can realize the movement, fixation and irradiation angle adjustment in nine directions. A doctor can hold the photographing device of the portable device with one hand to photograph the eye position, and gently dial the extension rod with the other hand to adjust the position of the pen lamp and attract the attention of the child, so as to independently and efficiently complete the eye position examination and photographing, improving the detection efficiency.

[0034] In this application, the relative angle of an object is adjusted through a rotating structure to achieve convenient operation or alignment with patients in different positions. The structure of this application is not specifically limited.

[0035] In one embodiment, the second rotating mechanism includes an external thread adapter and a locking bolt disposed at the bottom of the external thread adapter. The connecting rod 4 is connected to the shooting device fixing member 7 through the external thread adapter, and after the connecting rod 4 and the shooting device fixing member 7 rotate at an angle through the external thread adapter, the rotation position of the external thread adapter is fixed by the bottom locking bolt.

[0036] By providing an external thread adapter, the connecting rod 4 is connected to the shooting device fixing member 7 through the external thread adapter. After rotation is completed, the rotation position of the external thread adapter is fixed by the bottom locking bolt. The structure is simple, and arbitrary adjustment of the angle between the shooting device fixing member 7 and the connecting rod 4 can be achieved.

[0037] In this application, the external thread adapter can achieve quick connection, and there are no restrictions on its structure and dimensions. In one embodiment, it is a 1 / 4 external thread small pan-tilt head, that is, a 1 / 4-inch external thread with an external thread structure of about 6 mm. The lower shooting device fixing member 7 is connected and fixed by adjusting the tightness with a locking screw, and at the same time, the angle of the connecting rod 4 is adjusted.

[0038] This application includes but is not limited to the above-mentioned external thread adapter.

During the rotation of the external thread adapter, the scale line pointed to by the pointer on the scale disk changes, and the connecting rod 4 determines the rotation angle with the shooting device fixing member through the scale line pointed to by the pointer on the scale disk.

[0040] By providing a scale disk and a pointer, during the rotation of the external thread adapter, the scale line pointed to by the pointer on the scale disk changes, and the connecting rod 4 determines the rotation angle with the shooting device fixing member 7 through the scale line pointed to by the pointer on the scale disk, which can achieve precise control of the rotation of the external thread adapter and improve the detection efficiency.

[0041] A scale disk can be provided at the connection between the bottom end of the connecting rod 4, i.e., the small pan-tilt head, and the shooting device fixing member 7 to quickly determine the rotation angle.

[0042] This application includes but is not limited to using a scale disk and a pointer for precise angle detection, and there are no restrictions on its structure and setting method.

[0043] In the present application, the angle adjustment of the lamp tube of the commonly used ophthalmic pen light is achieved through a first rotating mechanism, and its specific structure is not limited. In one embodiment, the first rotating mechanism includes a ball head structure 3 arranged at the upper end of the connecting rod 4 and a ball socket lamp clamp arranged on the lamp fixture 1. The connecting rod 4 is connected to the ball socket lamp clamp through the ball head structure 3. The angle between the connecting rod 4 and the ball socket lamp clamp is controlled by the ball head structure 3 to control the light of the commonly used ophthalmic pen light to be aimed at the patient's eyes. After the angle between the connecting rod 4 and the ball socket lamp clamp reaches a predetermined angle, the ball socket lamp clamp is fastened by a ball head fastening bolt. The ball socket lamp clamp is a 3D printed ball socket lamp clamp or an injection molded ball socket lamp clamp, and the diameter of the ball head structure 3 is 10-15mm.

[0044] A ball head structure 3 is provided at the upper end of the connecting rod 4, which is combined with the ball socket lamp clamp to achieve angle adjustment of a commonly used pen light in ophthalmology, thereby improving detection efficiency.

[0045] It should be pointed out that in order to ensure the accuracy of detection in this application, the planes in which the rotation directions of the connecting parts at the upper and lower ends of the connecting rod 4 are generally different, and are generally vertical. In this way, the direction, spacing, etc. of the commonly used pen lights in ophthalmology can be adjusted in three-dimensional space, thereby improving detection efficiency.

[0046] This application does not limit the size of the ball head structure 3, the size of the ball socket lamp clip, and the materials and connection methods of the two.

[0047] In order to further improve the test efficiency, in one embodiment, the connecting rod 4 is a telescopic connecting rod 4 , and the telescopic connecting rod 4 is a rotating telescopic connecting rod 4 or a straight-pull telescopic connecting rod 4 .

[0048] By designing the connecting rod 4 as a retractable connecting rod 4, the telescopic function and eccentric tube design of the selfie stick are generally utilized to achieve adjustment of the length and angle, and finally the connection is ensured to be stable by tightening the screws, thereby achieving precise adjustment of the detection distance.

[0049] This application does not limit the material and size of the connecting rod 4.

The diameter of the connecting rod 4 is 8-18 mm, the length is 80-200 mm, or other sizes.

[0050] In this application, the corresponding lamp is fixed by a lamp fixture 1, and its material is not limited. The lamp fixture 1 is a soft rubber lamp fixture 1 or a silicone lamp fixture 1, or a lamp fixture 1 made of other materials.

[0051] Adjust the distance and angle between the lamp and the eyes by manually telescoping the connecting rod 4; ensure the stability of the required position by rotating and tightening the screws.

[0052] The lamp fixture 1 is detachably connected to the ball socket lamp clip, or the lamp fixture 1 and the ball socket lamp clip are of an integral structure, and the staff can select a suitable structural connection method according to needs.

[0053] In this application, the type of the photographing device is not limited. It can be a mobile phone, a camera, a tablet computer, or other types of photographing devices. This application does not make any limitations in this regard, and generally, a mobile phone can be used to achieve it.

[0054] To further improve the precise fixation of the photographing device and reduce the possibility of its position changing, in one embodiment, the portable children's eye position photographing device further includes an anti-slip soft pad provided in the photographing device fixing groove of the photographing device fixing member 7, which is used to prevent the photographing device in the photographing device fixing groove from slipping out of the photographing device fixing groove. The photographing device fixing member 7 is a photographing device fixing member 7 with an adjustable width of the photographing device fixing groove, which is used to clamp photographing devices of different width sizes. The photographing device fixing member 7 includes a first clamping arm and a second clamping arm. The first clamping arm and the second clamping arm form the photographing device fixing groove, and the first clamping arm and the second clamping arm are connected by a spring. The width of the photographing device fixing groove is adjusted by controlling the stretching state of the spring.

[0055] The anti-slip soft pad is used to prevent the photographing device in the photographing device fixing groove from slipping out of the photographing device fixing groove. This application does not limit the size, material, etc. of the anti-slip soft pad. By designing the photographing device fixing member 7 as a photographing device fixing member 7 with an adjustable width of the photographing device fixing groove, the clamping of photographing devices of different width sizes is realized, the adaptability of the product is improved, so there is no need to design separately for different models of photographing devices, and the use cost is reduced.

[0056] To further improve the test efficiency, in one embodiment, the portable children's eye position photographing device further includes a cartoon decorative object provided on the commonly used ophthalmic pen light, which is used to attract the attention of patients.

[0057] By setting a cartoon decorative object on the commonly used ophthalmic pen light to attract the attention of patients, the patient's eyes can be quickly oriented towards the pen light, thus improving the test efficiency.

[0058] This application does not limit the type and installation method of the cartoon decorative object.

[0059] In one embodiment, for the portable child eye position photographing device, the lamp fixture 1 uses a ball socket lamp clip. This lamp clip is made of soft rubber material, with a diameter of 10 - 15 mm, and can firmly hold a commonly used pen light in ophthalmology. The lower part of the lamp clip is integrally designed with a 13 mm ball socket, which is used to connect the 13 mm ball head at the upper end of the connecting rod 4. This design not only makes the overall specification of the lamp clip smaller and lighter, but also enhances the firmness, ensuring that the light of the pen light can always point to the child, thereby improving the accuracy and efficiency of diagnosis and treatment.

[0060] The upper end of the connecting rod 4 of the telescopic connecting rod 4 is provided with a 13 mm ball head, which is connected to the ball socket lamp clip. The middle part adopts the telescopic function of a mobile phone selfie stick and an eccentric tube design. The pipe diameter is customized to be 8 - 18 mm, and the extension rod has a length of 80 mm - 200 mm. The lower end of the connecting rod 4 is designed as a 1 / 4 external thread small pan-tilt head, and the tightness is adjusted through a locking screw, providing a 360-degree rotation function. After tightening the matching round hole lock, the rotation and fixation of the lamp clip can be realized, ensuring the stability and accuracy of the light direction.

[0061] The photographing device uses a mobile phone, and the photographing device fixture 7 uses a ball head mobile phone clip. Drawing on the principle of the 1 / 4 external thread small pan-tilt head, the lower part of the connecting rod 4 is transformed into a 1 / 4 external thread adapter with a locking screw and a 13 mm spherical shape, and then the 1 / 4 external thread adapter is connected to the ball head mobile phone clip as a whole.

[0062] Through this structure, the functions of fixing the photographing device, distance telescoping, and direction adjustment are realized. This improvement not only improves the flexibility and stability of the device, but also ensures the firm fixation of the photographing device at different photographing angles and distances, thereby further enhancing the efficiency and accuracy of eye position examination.

[0063] The portable device in this technical solution is designed specifically for fixing an ophthalmology pen light on a photographing device, and can realize movement, fixation, and irradiation angle adjustment in nine directions. In addition, light and cartoon objects can be decorated on the pen light to attract the attention of children. Through this design, a doctor can hold the photographing device with the portable device fixed in one hand for eye position photographing, and gently move the extension rod with the other hand to adjust the pen light direction and attract the attention of children, so as to independently and efficiently complete eye position examination and photographing.

[0064] The shooting device fixture 7 is used to fix the shooting device and allows the doctor to observe and shoot the eye position through the screen of the shooting device. The elastic property of the spring is utilized to achieve automatic clamping of the shooting device. The design needs to consider factors such as the stability of the clamping structure to ensure adaptation to shooting devices of different sizes and provide a stable clamping effect. The shooting device fixture 7 is made of aluminum alloy and soft rubber materials, and the clamping arms are equipped with anti-slip soft pads to ensure the shooting device is stable. Through the spring-loading mechanism, the shooting device fixture 7 can adapt to shooting devices of different sizes and ensure firm fixation. The shooting device is manually placed between the clamping arms, and the spring-loading mechanism will automatically adjust the clamping arms to adapt to the size of the shooting device and tighten it.

[0065] The lamp fixture 1 is used to fix the ophthalmic pen light and allows adjustment of the light irradiation angle. It is completed by using computer-aided design (CAD) software for modeling and simulation. The manufacturing may involve 3D printing technology or injection molding technology. The material selection and structure design should consider durability and connection stability. The lamp clip is made of soft rubber, with a diameter of 10 - 15 mm, and can clamp common ophthalmic pen lights. It is integrally designed with a 13 mm ball socket at the bottom. The soft rubber material ensures that the lamp fixture 1 can firmly clamp the pen light and provides a certain elasticity to adapt to pen lights of different diameters. The pen light is manually inserted into the lamp fixture 1, and the soft rubber material of the lamp fixture 1 ensures the stable fixation of the lamp, and the irradiation angle is adjusted through the ball socket and the matching nut 2.

[0066] The connecting rod 4 connects the shooting device fixture 7 and the lamp fixture 1, allowing telescopic adjustment of the angle and distance between the pen light and the eye. The overall design needs to consider material selection, structure design, the stability of the telescopic mechanism, and the reliability of the locking device to ensure that the connecting rod 4 can provide stable support and reliable angle adjustment function during use. The connecting rod 4 is made of aluminum alloy, with a pipe diameter of 8 - 18 mm and a length of 80 mm - 200 mm. The upper end is equipped with a ball head with a diameter of 13 mm, which is connected to the ball socket of the lamp clip. The lower end is designed as a 1 / 4 external thread small pan-tilt head, and the tightness is adjusted through a locking screw. By utilizing the telescopic function of the selfie stick and the eccentric tube design, the length and angle are adjusted. The locking screw ensures firm connection. By manually telescoping the connecting rod 4, the distance and angle between the lamp and the eye are adjusted; by rotating and locking the screw, the stability of the required position is ensured.

[0067] Through the second rotating component, the connection and 360-degree rotation between the fixing part of the shooting device and the connecting rod 4 are realized. The entire design needs to consider the material selection, structural design of the adapter fittings, and the reliability of the locking screws to ensure stable connection and flexible angle adjustment function during use. The adapter fittings include a 1 / 4 external thread adapter and a 13mm ball socket. The connecting rod 4 and the fixing part of the shooting device are fixed by locking screws. Through the cooperation of the 1 / 4 external thread and the ball socket, the adapter fittings can achieve 360-degree rotation and fixation at any angle. By tightening the screws to fix the required angle, the stability during the shooting process is ensured.

[0068] In the above solution, through the telescopic function of the connecting rod 4 and the fixing function of the locking screws, the portability and stability of the device are realized. The design of the ball socket base and the 1 / 4 external thread adapter ensures flexible adjustment in multiple directions, enabling the doctor to operate the device with one hand and easily adjust the lighting direction with the other hand. The doctor can hold the shooting device with the portable device fixed in one hand and adjust the connecting rod 4 and the lamp clip with the other hand to achieve nine-direction movement and fixation, ensuring that the pen light is always aligned with the child. The whole process is simple to operate, efficient and stable.

[0069] Through these technical implementation solutions and structural designs, the deficiencies of existing devices in pediatric eye position shooting are solved, enabling doctors to independently and efficiently complete eye position examination and shooting.

[0070] The usage process of the above solution is as follows:

[0071] Assemble the fixing part 7 of the shooting device and the fixing part 1 of the lamp (the shooting device clip and the lamp clip), and connect the fixing part 7 of the shooting device and the fixing part 1 of the lamp together through the connecting rod 4 and the adapter fittings.

[0072] Insert the pen light: Insert the pen light into the fixing part 1 of the lamp to ensure its stable fixation.

[0073] Adjust the connecting rod 4: Adjust the length and angle of the connecting rod 4 according to needs and adjust to the appropriate shooting position.

[0074] Fix the shooting device: Fix the shooting device on the fixing part 7 of the shooting device to ensure the stability of the shooting device.

[0075] Lock the screws: Fix all connection points through the locking screws to ensure the stability of all components.

[0076] Adjust the irradiation angle: Ensure that the light is aligned with the child's eyes by adjusting the rotation angle of the lamp clip ball socket base.

[0077] In terms of productivity, cost, energy conservation, etc., the above technical solution has the following advantages:

[0078] 1. Improve productivity: By simplifying the operating process and reducing the examination time, the time for a single eye position examination can be reduced from 30 minutes with existing technology to 10 minutes, thereby improving the efficiency of diagnosis and treatment.

[0079] 2. Reduce costs: Because the device is small and reusable, it reduces dependence on multiple doctors, saves labor costs, and reduces equipment procurement and maintenance costs.

[0080] 3. Energy saving: The use of efficient design and materials reduces energy consumption, making the equipment more energy-saving and environmentally friendly during use.

[0081] This technical solution is not only suitable for eye position diagnosis, qualitative and quantitative analysis, and photography needs in ophthalmology clinics and before and after surgery, but is also particularly suitable for children's eye position examination, improving the efficiency and accuracy of the diagnosis and treatment process.

[0082] To sum up, the portable children's eye position shooting device provided by the embodiment of the present invention fixes the shooting device by setting a shooting device fixing part, and connects the commonly used ophthalmic pen light fixed on the lamp fixing part through a connecting rod. The doctor can realize nine-direction movement, fixation and illumination angle adjustment.
