Description

Technical Field

[0001] The present application relates to the technical field of screening devices, and more specifically, to a handheld fundus disease screening device. Background Art

[0002] The prosthesis is an instrument for examining the vitreous body and fundus lesions at the back of the eye. Prosthesis fundus examination is a relatively common examination method. It mainly uses the principle of light to perform a detailed examination of the fundus and understand the condition of the fundus. It is of great significance for diagnosing diseases such as macular degeneration, retinal detachment, and retinal hemangioma.

[0003] The document with prior art announcement number CN221356843U provides an auxiliary device for examining the fundus with a front mirror. When in use, the doctor's left index finger passes through the first ring, the doctor's thumb passes through the second ring, and then the front mirror is taken out and placed vertically between the first fixed block and the second fixed block. The patient's fundus is then detected using the existing front mirror detection method. Due to the fixed rod, there is a certain distance between the doctor's index finger and the front mirror, so the doctor's index finger can be prevented from blocking the front mirror. Due to the presence of the first fixed block, the second fixed block and the fixed rod, the doctor's index finger and thumb are also prevented from contacting the front mirror. Therefore, when the doctor's middle finger contacts the index finger and thumb, it will not cause contamination to the front mirror.

[0004] Although this device has many beneficial effects, the following problems still exist: when medical staff put the front mirror on the table after using it, it is very easy for the lens of the front mirror to be scratched by foreign objects or other tools on the table, which can easily reduce the protective performance of the front mirror. In view of this, we propose a handheld fundus disease screening device. Utility Model Content
