Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fundus examination, and more particularly to a fundus examination device. Background Art
[0002] Retinopathy of prematurity (ROP) refers to premature infants born under 36 weeks of gestation, with low birth weight, and who have been receiving oxygen for extended periods. This condition can lead to fibroangiomatous proliferation and contraction of the non-vascularized retina, which can eventually cause tractional retinal detachment and blindness. With the rapid development of perinatal medicine and neonatology in my country, and the widespread establishment of neonatal intensive care units (NICUs), the survival rates of premature and low-birth-weight infants have significantly improved. Problems previously seen in developed countries, such as ROP, are on the rise in my country. The condition is also extremely detrimental to vision, with blindness nearly 100% of cases diagnosed in the late stages.
[0003] Fundus examinations on infants require a variety of medical instruments, each used separately, such as lighting equipment, medical magnifiers, or forehead reflectors. Doctors need to hold the magnifier during the examination, making it difficult to adjust the infant's head or eyes, hold the infant's eyelids open, or record the infant's condition. The magnifier also moves widely when lowering or moving, posing a risk of contact with the infant. Existing fundus examinations use separate instruments, making them inconvenient and potentially hazardous. There is a lack of integrated equipment suitable for fundus examinations. Utility Model Content
[0004] The present invention aims to overcome the defects of the above-mentioned prior art in that various medical devices are inconvenient to use during fundus examination and have certain safety hazards during use, and provides a fundus examination device that is convenient for doctors to use and improves the safety of the examination process.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a fundus examination device, including: a bracket, a first adjustment bracket, a second adjustment bracket and a third adjustment bracket respectively connected to the bracket, a medical magnifying glass connected to the first adjustment bracket, a medical reflector connected to the second adjustment bracket, and a lighting device connected to the third adjustment bracket, the medical magnifying glass is used to observe the patient's eye condition, the medical reflector is used to reflect light to the patient's eyes for easy observation, and the lighting device irradiates toward the medical reflector.
[0006] The medical devices needed for fundus examination, such as a medical magnifying glass and a medical reflector, are integrated into a bracket. The lighting device is also installed on the bracket, and each medical device is connected to the bracket via a first adjustment bracket, a second adjustment bracket, and a third adjustment bracket, respectively. This allows the medical magnifying glass, the medical reflector, and the lighting device to be moved and fixed separately, and can be moved to any position as needed to ensure usage. When the doctor needs to adjust the position of the baby's head or eyes, or need to hold the baby's eyelids open, or need to record the condition, the medical magnifying glass and the medical reflector can remain stable without affecting the doctor's operation, making the doctor's examination more convenient and preventing the medical magnifying glass from touching the baby when moving, thereby improving the safety of the examination. The lighting device is used for illumination. When in operation, the lighting device emits a light source, which illuminates the medical reflector. After reflection, the light passes through the medical magnifying glass and enters the patient's fundus. The doctor observes the patient's eye through the medical reflector and examines the patient's fundus. Specifically, the bracket can be placed on the ground or mounted on a medical bed or medical cart.

The screw 16 passes through the movable plate 15. When tightened, the nut 17 drives the movable plate 15 toward the fixed plate 14 to achieve clamping. Anti-slip pads 18 are provided on the clamping surfaces of the movable plate 15 and the fixed plate 14. The structures of the first adjustment frame 2, the second adjustment frame 3, and the third adjustment frame 4 are identical.
[0045] The slider 8 of the first adjustment frame 2 is slidably connected to the bracket 1, and a rotatable connecting rod 9 is provided. This can increase the adjustable range of the first adjustment frame 2 and make it applicable to more scenarios. The first adjustment frame 2 can be moved to the appropriate position, and then the connecting rod 9 is adjusted to the appropriate angle. Furthermore, the slider 8 is connected to a locking structure, which is used to fix the slider 8 after it stops. The locking structure can be a pin or a bolt. When a pin is used, multiple pin holes need to be provided on the bracket 1. When a bolt is used, the bolt is threadedly connected to the slider 8 and passes through the slider 8. After the bolt is tightened, its end abuts against the bracket 1 to lock it. The clamping member 13 is used to clamp the medical magnifying glass 5 and the medical reflector 6, which is convenient for use and removal. The nut 17 is used in conjunction with the screw 16 to achieve tightening and clamping. The clamping effect is better than that of ordinary clamps, fully ensuring stable clamping, preventing medical equipment or objects from falling, and ensuring safe operation. The anti-slip pad 18 is provided to further ensure the clamping temperature. Specifically, the anti-slip pad 18 is made of a flexible material, such as rubber, silicone, or flexible plastic. The first adjustment frame 2, the second adjustment frame 3, and the third adjustment frame 4 are configured with the same structure, which is convenient for use and saves manufacturing costs. Furthermore, the first adjustment frame 2, the second adjustment frame 3, and the third adjustment frame 4 are connected to the medical magnifying glass 5, the medical reflector 6, the lighting equipment 7, and the clamping member 13 via a ball joint, a universal joint coupling, or a ball joint, further enhancing the adjustment flexibility of each component.
[0046] In this embodiment, the lighting device 7 is connected to the connecting rod 9; the clamping member 13 is connected to the connecting rod 9, that is, the fixing plate 14 in the clamping member 13 is connected to the connecting rod 9. This embodiment is more suitable for working conditions where a large adjustment range is required for the lighting device 7, the medical magnifying glass 5, and the medical reflector 6.
[0047] The remaining features and working principles of this embodiment are consistent with those of embodiment 1.
[0048] Example 3
[0049] like Figure 1-5 As shown, based on Example 1 or Example 2, Example 1 or Example 2 is further limited, and the difference is that:
[0050] At least one rotating connector 10 is installed between the connecting rod 9 and the medical magnifying glass 5. One end of the rotating connector 10 is rotatably connected to the connecting rod 9, and the medical magnifying glass 5 is installed on the other end of the rotating connector 10. At least one of the rotating connectors 10 is a telescopic rod. A mobile bed 11 is also included.

The mobile bed 11 is provided with a storage basket 12 for placing medical equipment.
[0051] At least one rotatable connector is provided between the medical magnifying glass 5 and the connecting rod 9. The connector rotates relative to the connecting rod 9, thereby increasing the adjustable range of the medical magnifying glass 5. Specifically, significant damping is provided at the connection points between the slider 8 and the connecting rod 9, and at the connection points between the connecting rod 9 and the rotating connector 10, to ensure that the medical magnifying glass 5 remains stationary after rotational adjustment. This damping can be achieved by increasing friction at the rotational points, or by adding springs, as in the existing suspension bracket 1. Furthermore, if the medical magnifying glass 5 is heavy, fastening structures can be provided at these connection points to fully ensure the stability of the medical magnifying glass 5. At least one of the rotating connectors 10 is configured as a telescopic rod to further increase the adjustable range of the medical magnifying glass 5 and enhance its ease of use.
