Description

TECHNICAL FIELD

[0001] The application relates to the technical field of eye disease detection devices, in particular to an eye disease detection device. BACKGROUND

[0002] In the clinical diagnosis and treatment of thyroid-related eye diseases, accurate and repeatable measurement of exophthalmos is a core objective index for evaluating disease activity, guiding treatment decisions and judging curative effects. At present, the exophthalmometer or the method of visual comparison on the side of the patient with a transparent ruler is generally used for measuring exophthalmos. However, the exophthalmometer uses a mirror reflection optical system, so that the examiner reads the scale in the front view by aligning the corneal image, which produces a certain parallax. The whole measurement process is too dependent on the stability of the examiner's hand and the skill of the alignment operation. When reading the data, the medical staff needs to confirm the measurement data in the observation lens group back and forth, and the slight shaking of the hands of the medical staff can cause large data errors, affecting the accurate judgment of the disease. Although the method of visual comparison on the side of the patient with a transparent ruler can avoid the error caused by mirror reflection, it is difficult to keep the transparent ruler horizontal and aligned with the orbital rim of the patient during use, and it is inconvenient to read the degree.

Detailed Implementation

[0017] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0018] like Figures 1 to 13As shown, an ophthalmic disease detection device provided in this embodiment of the invention includes observation lens groups 3 on two convexity meters and two reference feet 21. The observation lens groups 3 can be the mirror portion inside the triangular cover of a conventional convexity meter, while the reference feet 21 are reference plates used in conventional convexity meters for aligning with the patient's orbital bone margin. It also includes a mounting frame 1 and a universal joint 4 mounted thereon. A mounting base 5 is mounted on the universal joint 4, and two movable seats 2 are symmetrically and horizontally slidably mounted on the mounting base 5. The two observation lens groups 3 are respectively mounted on the two movable seats 2. When the mounting base 5 moves, the universal joint 4 moves adaptively. The system includes a foot movement limiting component 6 that acts on the universal joint 4. The foot movement limiting component 6 automatically limits or releases the movement of the universal joint 4. Both movable seats 2 are equipped with transparent scales 7, and two reference footplates 21 are respectively installed at the zero positions of the two scales 7. That is, in use, the patient sits on a height-adjustable telescopic stool to allow their head to be positioned close to the two reference footplates 21 according to their height. Then, the medical staff holds the two movable seats 2 with both hands and aligns the two reference footplates 21 with the patient's orbital bone rim. This part of the usage is similar to existing technologies (e.g., ...). Figure 7 As shown), during this process, the universal joint 4 also moves adaptively. While moving the two movable seats 2, medical staff can lock the movement of the universal joint 4 using the foot-operated limiting component 6, thereby indirectly limiting the movement of the mounting seat 5. At this time, medical staff can release the two movable seats 2 and move backward to visually check whether the mounting seat 5 and movable seats 2 are perpendicular to the patient and parallel to the ground. Compared to manual adjustment, this allows for a better judgment of the correct position of the mounting seat 5 and movable seats 2. If a slight deviation is found, medical staff can again hold the two movable seats 2 and release the limiting on the universal joint 4 using the foot-operated limiting component 6. After the movable seats 2 have moved, the foot-operated limiting component 6 locks the universal joint 4 in its current state, and then the medical staff releases the movable seats. The movable seat 2 obtains the first data through two observation lens groups 3. Then, medical staff can stand on both sides of the patient and look at the scale 7 at eye level. At this time, the medical staff only need to observe the tangent scale line between the patient's protruding eye and the corresponding scale through the scale 7 to directly read the second data. The first data and the second data are added together and divided by two to calculate the average value, thereby reducing the error caused by optical reflection and making the data more accurate. In addition, the universal component 4 and the foot movement limiting component 6 enable medical staff to not only observe the position of the movable seat 2 and the mounting seat 5 from a distance, but also overcome the error caused by the tremor of the medical staff's hands when reading the protruding eye data. Preferably, the foot movement limiting component 6 is triggered by foot, so the medical staff do not need to release the movable seat 2 when limiting the universal component 4, making it more convenient to use.

[0019] like Figure 3 andFigure 6 As shown, in some embodiments, the universal assembly 4 includes a connector 401 mounted on the mounting bracket 1, a mounting rod 402 mounted on the connector 401, a ball joint 403 mounted on the top of the mounting rod 402, the ball joint 403 being slidably connected to the mounting base 5, and the foot movement limiting assembly 6 acting on the ball joint 403. That is, the ball joint 403 is designed to provide good movement space when the mounting base 5 moves within a certain range, and the sliding design between the ball joint 403 and the mounting base 5 can further expand the movement range of the mounting base 5. The foot movement limiting assembly 6 can also limit the sliding between the mounting base 5 and the ball joint 403.

[0020] like Figures 3 to 6 As shown, in some embodiments, the ball assembly 403 includes a first ball 4031 mounted on a mounting rod 402. A first arc-shaped cover 4032 is movably fitted onto the first ball 4031. A second arc-shaped cover 4036 is connected to the outer periphery of the first arc-shaped cover 4032 via a rod. A second ball 4033 is rotatably mounted inside the second arc-shaped cover 4036. A connecting cylinder 4034 is connected to the second ball 4033. A sliding rod 4035 is slidably inserted into the connecting cylinder 4034. The sliding rod 4035 is connected to the mounting base 5. During the movement of the mounting base 5, the sliding rod 4035 moves within the connecting cylinder 4034, and the first ball 4031 rolls within the first arc-shaped cover 4032, while the second ball 4033 rolls within the second arc-shaped cover 4036, achieving adaptive movement. The connecting member 401 includes a long cylinder 4011 vertically mounted on the mounting frame 1, and a mounting rod 402 vertically slidably inserted into the long cylinder 4011. A limiting screw 4012 is screwed into the outer side of the long cylinder 4011. The mounting rod 402 has a plurality of limiting holes 4013 vertically arranged for the limiting screw 4012 to be inserted. The movable design of the mounting rod 402 allows medical staff to control the height of the mounting base 5. This allows for adjustment according to the height of medical staff of different heights, making it more convenient for medical staff to measure patients' eye protrusion. A bracket 20 for placing the patient's chin is installed on the mounting rod 402. When the patient is examined for eye protrusion, the chin is placed on the bracket 20, which supports the patient's head, reduces fatigue in the patient's neck, and makes it less likely for the head to shake during the test.

[0021] like Figures 3 to 6As shown, in some embodiments, mounting cylinders 601 are installed on the outer sides of both the first arc-shaped cover 4032 and the second arc-shaped cover 4036. A pneumatic rod 602 is slidably inserted into the mounting cylinder 601. One end of the pneumatic rod 602 is configured with a pressure plate 603 for contacting the first ball 4031 or the second ball 4033. Multiple mounting cylinders 601 are connected by a pipe assembly 604. The pipe assembly 604 has two connecting ends. One connecting end is connected to a sliding rod 4035 via a first flexible tube 605. A stop plate 608 for contacting the inner wall of the connecting cylinder 4034 is symmetrically slidably installed inside the sliding rod 4035. The other connecting end is connected to a second flexible tube 607. The foot movement limiting component 6 includes a connection with the second flexible tube 607. The foot pedal 606 is connected to a free end and is externally connected to an air source, which can be an air compressor. The air pipe of the air compressor is connected to the foot pedal 606. After the mounting base 5 is moved into position, the medical staff steps on the foot pedal 606. The high-pressure air enters the foot pedal 606 and then enters the first flexible tube 605 and the second flexible tube 607, thereby increasing the internal pressure of the mounting cylinder 601 and the sliding rod 4035. This forces the sliding rod 4035 to move so that the abutment plate 608 abuts against the inner wall of the connecting cylinder 4034. The pneumatic rod 602 will also abut against the first ball 4031 or the second ball 4033 due to the increased air pressure in the mounting cylinder 601. This limits the degree of automatic movement of the universal assembly 4 and makes it easy to use.

[0022] like Figures 8 to 13 As shown, in some embodiments, the foot pedal 606 includes a mounting cover 6061, on which a foot pedal 6062 is mounted. An elastic reset member 8 is installed between the foot pedal 6062 and the mounting cover 6061. The mounting cover 6061 has an air inlet 6063 and an air outlet 6064. Specifically, the air inlet 6063 is connected to an external air source. The mounting cover 6061 has a cavity 6065 communicating with the air inlet 6063 and the air outlet 6064. The second flexible tube 607 connects to the air outlet... The vent 6064 is connected, and a movable plate 6066 that blocks the vent 6064 is slidably installed in the cavity 6065. When the foot pedal 6062 is pressed, the movable plate 6066 is moved by the elastic reset member 8 so that it no longer blocks the connection between the vent 6064 and the cavity 6065. That is to say, after the foot pedal 6062 is pressed, the movable plate 6066 will no longer block the vent 6064 by the elastic reset member 8, so that high-pressure gas can enter the vent 6064 to complete the limiting of the universal assembly 4.

[0023] like Figures 8 to 13As shown, in some embodiments, the elastic reset member 8 includes a hinge rod 801 hinged to the bottom surface of the foot pedal 6062. A hinge cylinder 802 is elastically slidably fitted on the hinge rod 801. Specifically, the portion of the hinge rod 801 located inside the hinge cylinder 802 has an annular plate. A spring is installed between the annular plate and the hinge cylinder 802. The hinge cylinder 802 is hinged to the mounting cover 6061. One end of the movable plate 6066 passes through the cavity 6065 and has a vertically constructed movable groove 803. One end of the hinge rod 801 passes through the hinge cylinder 802 and has a column rod 804. The column rod 804 slides tangentially within the movable groove 803. That is, when the foot pedal 6062 is pressed, it will cause the hinge rod 801 to move. Because the hinge rod 801 slides through the hinge cylinder 802, it will move along the axis of the hinge cylinder 802. At this time, the hinge cylinder 802 rotates adaptively. The sliding of the hinge rod 801 on the hinge cylinder 802 forces the column rod 804 to move within the movable groove 803, thereby causing the moving plate 6066 to move horizontally. In this embodiment, when the medical staff releases the foot pedal 6062, it will rotate and reset, causing the moving plate 6066 to again block the connection between the air vent 6064 and the cavity 6065. Preferably, one end of the foot pedal 6062 is rotatably mounted on the mounting cover 6061 via a shaft 9. A limit plate 10 is constructed on one side of the shaft 9. The mounting cover 6061 is horizontally... A baffle 11 is elastically slidably mounted. One end of the baffle 11 has a forcing inclined surface 12 for contacting the limiting plate 10. A foot pedal 13 located on one side of the foot pedal 6062 is vertically slidably mounted on the mounting cover 6061. A through groove 14 is formed through the baffle 11. The end of the through groove 14 away from the forcing inclined surface 12 has an inclined surface 15. A wedge-shaped rod 16 is vertically constructed on the foot pedal 13 for contacting the inclined surface 15. That is, after the foot pedal 6062 is pressed, the limiting plate 10 will rotate and contact the forcing inclined surface 12, thereby causing the baffle 11 to move so that the limiting plate 10 passes through the baffle 11. When the foot pedal 6062 is released, the limiting plate 10 is now located on the baffle 11. The bottom of the foot pedal 6062 is closed, so the limiting plate 10 will contact the bottom surface of the baffle 11, thereby restricting the reset of the foot pedal 6062. Medical personnel do not need to continuously press the foot pedal 6062 to limit the universal joint 4. When it is necessary to release the limit on the universal joint 4, pressing the foot pedal 13 will move the wedge rod 16, causing the inclined surface of the wedge rod 16 to contact the inclined surface 15, forcing the baffle 11 to move away from the shaft 9. Under the action of the elastic reset member 8, the limiting plate 10 will move and reset, indirectly causing the foot pedal 6062 to move and reset. At this time, the high-pressure gas in the vent 6064 will enter the exhaust chamber 6068 from the exhaust port 6067 of the moving plate 6066. Because the exhaust chamber 6068 is connected to the outside,Therefore, the gas inside the mounting cylinder 601 and sliding rod 4035 will be released to facilitate the movement of the mounting base 5 by medical staff.

[0024] like Figure 5 As shown, in some embodiments, the movable seat 2 is slidably mounted on the mounting base 5. A drive plate 17 is vertically slidably mounted inside the mounting base 5. The drive plate 17 is symmetrically constructed with abutting blocks 18 for contacting the inner wall of the movable seat 2. A drive screw 19 is vertically and rotatably mounted on the mounting base 5. The abutting blocks 18 are slidably mounted on the drive screw 19. Specifically, the mounting base 5 is provided with a scale to facilitate medical personnel in reading the patient's interpupillary distance. Rotating the drive screw 19 will cause the drive plate 17 to move, thereby causing the abutting blocks 18 on the drive plate 17 to abut against the inner wall of the movable seat 2. By increasing friction, the sliding of the movable seat 2 is limited, preventing accidental movement of the patient from causing the movable seat 2 to slide, and facilitating secondary measurement.

[0025] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
