Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ophthalmic clinical examination bracket and a device thereof. Background Art

[0002] During clinical ophthalmic examinations, patient stability directly impacts the accuracy of examination results, and this is particularly important during high-precision examinations such as fundus examinations and retinal scans. Traditional ophthalmic examination stands typically rely on manual adjustment, requiring doctors or nurses to make multiple fine-tuning adjustments based on the patient's facial structure to ensure patient stability. However, this process is often limited by the operator's experience and judgment, and can easily lead to slight deviations of the patient's head, chin, and face, which in turn affects the accuracy of the examination. This manual operation not only increases the workload of medical staff, but can also cause discomfort to patients during the adjustment process, increase examination time, and reduce patient cooperation. When performing an eye examination using a microscope or ophthalmoscope, the distance between the doctor and patient is close, posing a risk of droplet transmission. This is especially true when the patient coughs, sneezes, or talks, as respiratory droplets can become airborne, increasing the risk of infection for both the doctor and the patient.

[0003] Furthermore, many existing examination stand designs utilize a rigid support structure. While this rigid support provides a certain degree of stability, it lacks the flexibility to adapt to the patient's facial shape, often leading to discomfort during prolonged use. This is particularly true during ophthalmic examinations, which require maintaining the same posture for extended periods. The pressure caused by the rigid support can cause discomfort, affecting patients' tolerance and cooperation, leading to unstable examination results.

[0004] Existing technologies have proposed several automated support and fixation solutions, attempting to achieve automated adjustment through mechanical devices or hydraulic systems. However, most existing technologies still have limitations, such as incomplete fixation mechanisms, insufficient flexible support, low automation levels, and complex equipment operation. These limitations make it difficult to fully meet the requirements for patient stability, comfort, and operational efficiency required for high-precision ophthalmic examinations. Summary of the Invention

[0005] To address these issues, the present invention provides an ophthalmic clinical examination stand and device. Through the automated design of the support mechanism, first fixing mechanism, and second fixing mechanism, the stand automatically adjusts to ensure secure support for the patient's chin, cheeks, and forehead. The flexible support of the water and air bladders provides personalized support tailored to the patient's facial features, avoiding the discomfort associated with rigid supports. The protective plate and retractable baffle prevent the spread of droplets between the doctor and the patient during an ophthalmic examination.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: An ophthalmic clinical examination stand comprises a fixing frame, wherein the fixing frame comprises side panels and a bottom panel, and further comprises: a support mechanism mounted on the bottom of the bottom panel for supporting the patient's chin; two first fixing mechanisms mounted on both sides of the bottom panel and arranged in cooperation with the support mechanism for fixing the patient's cheeks; and a second fixing mechanism mounted on the side panels and arranged in cooperation with the support mechanism for fixing the patient's forehead.

[0007] This design can effectively prevent the patient's head and face from moving during the examination, thereby ensuring the accuracy of the examination and improving the doctor's operating efficiency. At the same time, it can reduce the patient's discomfort, improve the patient's cooperation, and increase the accuracy of clinical examinations.

[0008] Furthermore, the support mechanism includes a base, a support seat and a water bag; the base is installed on the bottom plate; the support seat is connected to the bottom plate through a first telescopic member, and two second telescopic members are provided between the support seat and the base; the water bag is installed on the support seat.

[0009] The water bag provides flexible support to ensure that the patient's jaw is firmly and comfortably supported during the examination Furthermore, a third fixing mechanism is installed on both sides of the water bag to assist in fixing the chin.

[0010] Furthermore, the third fixing mechanism includes a fixing plate, a fixing seat and a fixing block; the fixing plate is movably mounted on the support seat, connected to the water bag through a first hydraulic push rod, and a flexible connecting belt is provided between the fixing plate and the first hydraulic push rod; the fixing seat is mounted on the support seat; the fixing block is mounted in the fixing seat, and connected to the water bag through a second hydraulic push rod, for pushing the fixing plate to assist in fixing the chin.

[0011] By adjusting the position and angle of the fixation plate, the patient's jaw can be effectively fixed.

[0012] Furthermore, sliding grooves are provided on both sides of the support seat, and the first fixing mechanism is slidably provided in each of the sliding grooves.

[0013] Furthermore, the first fixing mechanism includes a sliding block and a pushing block; the sliding block is a T-shaped structure, one end of which is clamped in the sliding groove and the other end abuts against the side wall of the base plate; the pushing block is connected to the top of the sliding block and is movably connected to the base plate.

[0014] The design of the slide groove and sliding block ensures that the fixing mechanism can be adjusted automatically and smoothly, reducing human operation errors.

[0015] Furthermore, the second fixing mechanism includes two gear assemblies, two turntables, an airbag and a fixing ring; the two gear assemblies are installed between the support seat and the side panel; the two turntables are installed on the side panel and rotate synchronously with the gear assemblies through a synchronizing member; the airbag is installed on the side panel, and the air inlet is connected to the two second telescopic members through an air inlet pipe; the fixing ring is a U-shaped structure, and the two ends are respectively connected to the side panel through elastic members, and the two ends are respectively connected to the turntable through connecting members.

[0016] The airbag design provides flexible support and can be adjusted according to the shape of the patient's forehead, reducing the sense of pressure and enhancing the patient's comfort. It can also be used with a fixed ring to fix the patient's forehead.

[0017] An ophthalmic clinical examination device includes the examination bracket as described above and a protective cover, wherein the protective cover includes: a protective plate, installed on the side of a microscope lens, with a hole in the middle that can pass through the microscope lens, used to prevent the spread of respiratory diseases between doctors and patients during microscope observation; a telescopic baffle, installed on the side of a fundus lens, with a hole in the middle that can pass through the fundus lens, used to prevent the spread of respiratory diseases between doctors and patients during fundus observation.

[0018] The beneficial effects of the present invention are: 1. The inspection bracket of the present invention realizes automatic adjustment in many aspects, greatly improving the efficiency of use and operation accuracy, and reducing human intervention. When the patient's chin is placed on the water bag of the support seat, the fixing plate fixes the two sides of the chin along with the first hydraulic push rod and the second hydraulic push rod. The cooperation of the slide groove and the sliding block can automatically fix the patient's cheeks. At the same time, the support seat moves down to inflate the air bag to provide support for the patient's forehead. The rotation of the gear assembly drives the turntable to rotate, and then pulls the fixing ring to fix the patient's forehead, and a reset structure is provided. It can quickly and automatically adjust and restore to the initial state. The inspector can quickly complete the patient's preparation work, reducing the time the patient needs to wait before the examination and improving the efficiency of clinical diagnosis.

[0019] 2. The examination stand of this invention utilizes water and air bladders as flexible supports, eliminating the pressure on the patient's chin, face, and forehead caused by traditional rigid supports, significantly improving patient comfort. The design of the water and air bladders provides personalized support based on the patient's facial features, reducing discomfort during the examination and enhancing patient compliance, making it particularly suitable for prolonged examinations.

[0020] 3. The precise design of the support mechanism, first securing mechanism, and second securing mechanism effectively addresses the issue of head and facial instability in the patient's head and face, ensuring that the patient's chin, cheeks, and forehead are securely supported during an ophthalmic examination. This stability reduces examination errors caused by involuntary movements, thereby improving the accuracy of ophthalmic examinations. This is particularly advantageous in high-precision procedures such as fundus and retinal examinations.

[0021] 4. The protective plate and retractable baffle in the protective cover of this invention prevent the spread of droplets between doctors and patients during ophthalmic examinations, especially when using a microscope or ophthalmoscope, ensuring a hygienic and safe examination. The hole design avoids interference with microscopic or ophthalmoscope observation and does not affect the doctor's operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0038] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "front end", "back end", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0039] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] Example 1 Refer to the attached Figure 1-14An ophthalmic clinical examination bracket shown in the figure includes a fixing frame 1, which includes a side panel 12 and a bottom panel 11. The side panel 12 is provided with a hole for passing a slit lamp. The examination bracket also includes a support mechanism 2, two first fixing mechanisms 3 and a second fixing mechanism 4; the support mechanism 2 is installed at the bottom of the bottom panel 11 for supporting the patient's chin; the first fixing mechanism 3 is installed on both sides of the bottom panel 11 and is arranged in cooperation with the support mechanism 2 for fixing the patient's cheek; the second fixing mechanism 4 is installed on the side panel 12 and is arranged in cooperation with the support mechanism 2 for fixing the patient's forehead.

[0041] During the examination, support mechanism 2 provides firm support for the patient's chin. Flexible adjustment of the first fixing mechanism 3 ensures facial stability, preventing facial movement from affecting ophthalmic examination results and improving examination accuracy. The second fixing mechanism 4 secures the patient's forehead, ensuring head stability and enhancing examination accuracy. This design effectively prevents head and facial movement during the examination, ensuring examination accuracy and improving the doctor's operating efficiency. It also reduces patient discomfort, improves patient cooperation, and increases the accuracy of clinical examinations.

[0042] The support mechanism 2 includes a base 21, a support seat 22, and a water bag 23. The base 21 is mounted on the bottom plate 11. The support seat 22 is connected to the bottom plate 11 via a first telescopic member 24, and two second telescopic members 25 are provided between the support seat 22 and the base 21. The water bag 23 is mounted on the support seat 22, and a spring is installed in the water bag 23. It should be noted that the first telescopic member 24 and the second telescopic member 25 can optionally adopt a telescopic sleeve structure. The support mechanism 2 is formed by the base 21 and the support seat 22 to form a support function, and the water bag 23 provides flexible support to ensure that the patient's chin is firmly and comfortably supported during the examination. The extension and retraction of the first telescopic member 24 and the second telescopic member 25 are controlled by downward pressure on the patient's chin.

[0043] A third fixing mechanism 5 is installed on both sides of the water bladder 23 to assist in securing the chin. The third fixing mechanism 5 comprises a fixing plate 51, a fixing seat 52, and a fixing block 53. The fixing plate 51 is movably mounted on the support base 22 and connected to the water bladder 23 via a first hydraulic push rod 54. A flexible connecting belt 55 is provided between the fixing plate 51 and the first hydraulic push rod 54. The fixing seat 52 is mounted on the support base 22 and located behind the fixing plate 51. The fixing block 53 is mounted within the fixing seat 52 and connected to the water bladder 23 via a second hydraulic push rod 56. It is used to push the fixing plate 51 to assist in securing the chin. During use, the patient's chin presses against the water bladder 23 of the support seat 22. The liquid in the water bladder 23 enters the first hydraulic push rod 54 and the second hydraulic push rod 56. At this point, the first hydraulic push rod 54 extends, and the connecting belt 55 moves in the direction of the extension of the first hydraulic push rod 54, thereby driving the fixed plate 51 to move synchronously. Simultaneously, the liquid in the water bladder 23 enters the second hydraulic push rod 56, pushing the fixed block 53 forward and abutting the rear side of the fixed plate 51, thereby securing the fixed plate 51 to both sides of the patient's chin. It should be noted that the connecting belt 55 has a certain degree of hardness, enabling the fixed plate 51 to move upward under the connection belt 55. A spring is provided between the fixed block 53 and the fixed seat 52. When the patient lifts his chin, the spring in the water bladder 23 resets, and the liquid in the first and second hydraulic push rods 54, 56 returns to the water bladder 23, causing the fixed block 53 to reset under the action of the spring. The third fixing mechanism 5 can adjust the position and angle of the fixing plate 51 by adjusting the first hydraulic push rod 54 and the second hydraulic push rod 56, thereby effectively assisting in fixing the patient's chin, providing more comfortable support and fixation, and avoiding the accuracy of the examination affected by the unstable chin position. At the same time, the spring return function can ensure that when the patient raises his chin, the fixing device quickly returns to its original state, thereby improving the convenience and flexibility of the equipment.

[0044] Slide grooves 221 are provided on both sides of the support seat 22, and the first fixing mechanism 3 is slidably provided in each of the slide grooves 221. The first fixing mechanism 3 includes a sliding block 31 and a pushing block 32; the sliding block 31 is a T-shaped structure, one end of which is clamped in the slide groove 221 and the other end abuts against the side wall of the base plate 11; the pushing block 32 is connected to the top of the sliding block 31 and is movably connected to the side wall of the base plate 11. The fixing mechanism makes the adjustment more stable and less prone to displacement or offset due to the T-shaped clamping form of the sliding block 31. When the patient presses down on the chin, the support seat 22 moves down. Since the sliding block 31 is clamped in the slide groove 221 and abuts against the side wall of the base plate 11, the two pushing blocks 32 move toward the middle to fix the patient's cheek. When the patient lifts his chin, the support seat 22 moves up, the sliding block 31 moves to both sides, and the pushing block 32 returns to its original position. The design of the slide groove 221 and the sliding block 31 ensures that the fixing mechanism can be adjusted automatically and smoothly, reducing human operation errors, making the patient's fixation during the examination more precise and easy to adjust, and improving the convenience and accuracy of the examination.

[0045] The second fixing mechanism 4 includes two gear 49 assemblies, two rotating disks 41, an air bag 42, and a fixing ring 43. The two gear 49 assemblies are mounted between the support base 22 and the side plate 12. The gear 49 assembly includes a rack 48 and a gear 49. The rack 48 is mounted on the support base 22, and the gear 49 is mounted on the side plate 12 and meshes with the rack 48. The two rotating disks 41 are mounted on the side plate 12 and rotate synchronously with the gear 49 assemblies via a synchronizer. The air bag 42 is mounted on the side plate 12, and the air inlet is connected to the two second telescopic members 25 via an air inlet pipe 45. The fixing ring 43 is a U-shaped structure, with both ends connected to the side plate 12 via elastic members 46, and both ends connected to the rotating disk 41 via connecting members 47. It should be noted that the synchronizer can be a synchronization chain 44, the elastic member 46 can be a spring, and the connecting member 47 can be a connecting rope. During use, the patient's chin is placed on the support base 22, which moves downward, shortening the second telescopic member 25. The air in the second telescopic member 25 enters the airbag 42 through the air inlet pipe 45, providing flexible support for the forehead. Simultaneously, as the support base 22 moves downward, the rack 48 also moves downward, and the gear 49 meshing with the rack 48 rotates. The turntable 41 rotates in response to the rotation of the gear 49. The rotation of the turntable 41 drives the connecting member 47 to rotate and wrap around the turntable 41. Under the pull of the connecting member 47, the fixing ring 43 moves toward the airbag 42, securing the patient's forehead. When the patient raises their chin, the support base 22 moves upward, and the rack 48 moves upward with it. The gear 49 rotates in the opposite direction, causing the connecting member 47 to gradually fall off the turntable 41. The fixing ring 43 is then restored to its original position by the action of the elastic member 46. Secondary fixation mechanism 4, utilizing an airbag 42 and a synchronously rotating gear system 49, provides precise and comfortable support for the patient's forehead, preventing forehead instability from affecting examination accuracy. The airbag 42 provides flexible support that adjusts to the patient's forehead shape, reducing pressure and enhancing patient comfort. A spring-loaded return mechanism ensures automatic return to normal position when the patient raises their head, enhancing the device's automation and convenience.

[0046] A mounting bracket 13 is mounted on the fixing bracket 1 so that the fixing bracket 1 is mounted on the slit lamp.

[0047] The working principle of the inspection bracket and the protective cover in this embodiment is as follows: First, the patient's chin presses against the water bladder 23 of the support base 22. The water in the water bladder 23 enters the first hydraulic push rod 54 and the second hydraulic push rod 56. At this time, the first hydraulic push rod 54 extends, and the connecting belt 55 moves in the same direction as the first hydraulic push rod 54, thereby driving the fixed plate 51 to move synchronously. At the same time, the liquid in the water bladder 23 enters the second hydraulic push rod 56, pushing the fixed block 53 forward and abutting the back side of the fixed plate 51, so that the fixed plate 51 fixes both sides of the patient's chin. When the patient raises his chin, the liquid in the first and second hydraulic push rods 54, 56 returns to the water bladder 23, and the fixed block 53 returns to its original position under the action of the spring.

[0048] Synchronously, when the patient's chin is placed on the support seat 22, the support seat 22 moves down. Since the sliding block 31 is engaged in the slide groove 221 and abuts against the side wall of the base plate 11, the two pushing blocks 32 move toward the middle to fix the patient's cheeks. When the patient raises his chin, the support seat 22 moves up, the sliding block 31 moves to both sides, and the pushing block 32 is reset.

[0049] Simultaneously, when the patient's chin is placed on the support base 22, the support base 22 moves downward, shortening the second telescopic member 25. The gas in the second telescopic member 25 enters the airbag 42 through the air inlet pipe 45, providing flexible support for the forehead. Simultaneously, as the support base 22 moves downward, the rack 48 also moves downward, and the gear 49 meshing with the rack 48 rotates. The turntable 41 rotates in response to the rotation of the gear 49. The rotation of the turntable 41 drives the connecting member 47 to rotate and wrap around the turntable 41. Under the pull of the connecting member 47, the fixing ring 43 moves toward the airbag 42, securing the patient's forehead. When the patient lifts their chin, the support base 22 moves upward, the rack 48 follows, and the gear 49 rotates in the opposite direction. The connecting member 47 gradually falls off the turntable 41, and the fixing ring 43 is restored under the action of the elastic member 46.

[0050] Example 2 Based on Example 1, Example 2 provides a specific structure of an ophthalmic clinical examination device, comprising the examination stand described above, and a protective cover, the protective cover comprising a protective plate 6 and a retractable baffle 7: the protective plate 6 is mounted on the side of the microscope lens and has a hole in the middle that allows the microscope lens to pass through, thereby preventing the spread of respiratory diseases between the doctor and the patient during microscopic observation; the retractable baffle 7 is mounted on the side of the fundus lens and has a hole in the middle that allows the fundus lens to pass through, thereby preventing the spread of respiratory diseases between the doctor and the patient during ophthalmoscope observation. The retractable baffle 7 can be retracted when not in use, reducing the occupied area. The provision of the protective plate 6 and retractable baffle 7 can effectively block airborne bacteria and viruses, preventing the spread of droplets between the doctor and the patient during the ophthalmic examination, especially when using a microscope or ophthalmoscope, ensuring the hygienic and safe examination. The hole design can avoid interference with microscopic or ophthalmoscope observation without affecting the physician's operation.

[0051] Specific application cases: When necessary, the specific application method of an ophthalmic clinical examination bracket and its device of the present application is: Before use, the fixing frame 1 is installed at the examination position corresponding to the slit lamp. The protective plate 6 and the telescopic baffle 7 can be installed as needed to protect the patient and the doctor.

[0052] The patient's chin then presses against the water bladder 23 in the support base 22. The water in the water bladder 23 enters the first and second hydraulic push rods 54 and 56, causing the fixation plate 51 to secure both sides of the patient's chin. The flexible support provided by the water bladder 23 ensures that the patient's chin is firmly and comfortably supported during the examination. Adjustment of the first and second hydraulic push rods 54 and 56 adjusts the position and angle of the fixation plate 51, effectively assisting in securing the patient's chin.

[0053] Synchronously, when the patient's chin is placed on the support base 22, the support base 22 moves downward, causing the two push blocks 32 to move toward the middle to fix the patient's cheeks. The design of the slide 221 and the sliding block 31 ensures that the fixing mechanism can be adjusted automatically and smoothly, reducing human operation errors.

[0054] Synchronously, when the patient's chin is placed on the support base 22, the support base 22 moves downward, shortening the second telescopic member 25. The gas in the second telescopic member 25 enters the airbag 42 through the air inlet pipe 45, providing flexible support for the forehead. Simultaneously, when the support base 22 moves downward, the gear 49 assembly rotates, and the turntable 41 rotates accordingly. The rotation of the turntable 41 drives the connecting member 47 to rotate and wrap around the turntable 41. Under the pull of the connecting member 47, the fixing ring 43 moves toward the airbag 42, securing the patient's forehead. The airbag 42 and the synchronously rotating gear 49 system provide precise and comfortable fixed support for the patient's forehead, preventing the instability of the forehead from affecting the accuracy of the examination.

[0055] Once the fixation is complete, start the inspection.

[0056] After the examination of the patient is completed, when the patient raises his chin, the liquid entering the first hydraulic push rod 54 and the second hydraulic push rod 56 returns to the water bag 23, and the fixed block 53 is reset under the action of the spring; similarly, the support seat 22 moves up, the sliding block 31 moves to both sides, and the push block 32 is reset; similarly, the support seat 22 moves up, the rack 48 follows and moves up, the gear 49 rotates in the opposite direction to the previous direction, the connecting member 47 gradually falls off from the turntable 41, and under the action of the elastic member 46, the fixed ring 43 is reset.
