Direct ophthalmoscope dustproof clamp sleeve for ophthalmology department

Abstract

The invention relates to a direct ophthalmoscope dustproof clamp sleeve for an ophthalmology department. The direct ophthalmoscope dustproof clamp sleeve comprises a sleeve body for being arranged on a direct ophthalmoscope in a sleeving mode. The sleeve body is hollow, one end of the sleeve body is closed, and the other end of the sleeve body is open. An entrance and exit which can be opened or closed and allow the direct ophthalmoscope to enter or exit is formed in the sleeve body. A handle used for opening the entrance and exit is arranged on the sleeve body, and the entrance and exit in the sleeve body is in the closed state under no external force action. When the direct ophthalmoscope dustproof clamp sleeve is in use, the entrance and exit in the sleeve body is opened by pressing the handle through external force, then, a lens of the direct ophthalmoscope is directly sleeved with the sleeve body, and the lens is wrapped with the sleeve body, so that the dustproof effect is achieved. When the direct ophthalmoscope needs to be in use, the sleeve body is opened by pressing the handle and the sleeve body is taken down from the lens of the direct ophthalmoscope so that the direct ophthalmoscope can be used. The direct ophthalmoscope dustproof clamp sleeve is simple in structure, convenient to use and capable of effectively achieving the dustproof effect on the direct ophthalmoscope, dust is prevented from entering the direct ophthalmoscope, the lens is protected, the service life is prolonged, and the cost is greatly saved.

Description

technical field [0001] The invention relates to a dustproof jacket, in particular to a dustproof jacket for ophthalmic direct ophthalmoscope. Background technique [0002] The lens shell of the direct ophthalmoscope currently used is connected together by two housings, and then the lens is wrapped in the shell, and due to the connection, there is a gap at the joint around the shell, and the direct ophthalmoscope The lens of the ophthalmoscope has nothing to cover the lens. After a long time, the dust will easily enter the inside through the gap on the lens and adhere to the lens. After the dust enters the inside of the ophthalmoscope, it cannot be wiped with lens cleaning paper, so the dust will More and more, it not only affects clinical ophthalmologists to perform fundus examination; it also reduces the service life of ophthalmoscopes. Moreover, the ophthalmoscope is all black, which is not attractive enough for children's ophthalmology examinations for young children, an...

Problems solved by technology

[0002] The lens shell of the direct ophthalmoscope currently used is connected together by two housings, and then the lens is wrapped in the shell, and due to the connection, there is a gap at the joint around the shell, and the direct ophthalmoscope The lens of the ophthalmoscope has nothing to cover the lens. After a long time, the dust will easily enter the inside through the gap on the lens and adhere to the lens. After the dust enters the inside of the ophthalmoscope, it cannot be wiped with lens cleaning paper, so the dust will More and more, it not only affects clinical ophthalmologists to perform fundus examination; it also reduces the service life of ophthalmoscopes

In addition, the ophthalmoscope is completely black, which is not attractive enough for children's ophthalmology examinations for young children, and even causes panic in children who are unable to cooperate with the examination.

[0003] The direct ophthalmoscope is the most commonly used tool for doctors to check the eyes, so its usage rate is very high. If the lens is wrapped directly with a general cloth bag, the cloth bag needs to be disassembled every time it is used, which is very troublesome. Not only increases the workload, but also brings inconvenience to the work, the applicability is not great

The price of direct ophthalmoscope is also relatively expensive. If the lens cannot be effectively dust-proofed, the lens will be covered with dust easily. If the cause is well detected, the patient cannot be treated well. At this time, the direct ophthalmoscope must be replaced, which greatly increases the cost
