Description

Technical Field

[0001] The utility model relates to the technical field of microscopes, in particular to an isolation device for a slit lamp microscope and a microscope. Background Art

[0002] In ophthalmic examination, the slit lamp microscope is the most frequently used optical device. It consists of a lighting system and a binocular microscope. Through the slit lamp microscope, the eyelid, conjunctiva, sclera, cornea, anterior chamber, iris, pupil, lens and the front 1 / 3 of the vitreous body can be clearly observed, and the location, nature, size and depth of the lesion can be determined. If equipped with accessories, the inspection range will be wider. Therefore, the slit lamp microscope is an important equipment for ophthalmologists to examine. In addition to the left and right swing function, the machine also has a three-dimensional adjustable mobile workbench to facilitate multi-angle observation of the patient's eyes during examination.

[0003] During the examination, the patient sits opposite the binocular microscope and places his lower jaw on the machine's jaw frame. The jaw frame device can fix the patient's head, with the forehead close to the headrest, and the headrest and jaw frame fix the patient's head. The doctor can move the microscope forward, backward, left and right by operating the slide handle to adjust the distance and direction to see the internal structure of the patient's eyes as clearly as possible, so as to find the problematic parts. During the movement forward, backward, left and right, the distance between the examiner and the person being examined will be very close. Even if both parties wear masks, they can still feel each other's breathing gas, especially when one party suffers from respiratory diseases, which can easily be transmitted through the respiratory tract.

[0004] At present, the slit lamp microscopes on the market are constantly moving during the inspection, resulting in the two parties being too close to each other, which leads to the spread of respiratory diseases. Especially during the COVID-19 pandemic, the protection against respiratory infectious diseases does not meet the requirements, which can easily lead to the spread of respiratory diseases. Utility Model Content

[0005] In view of the above problems, the first object of the utility model is to provide an isolation device for a slit lamp microscope, which can isolate doctors and patients to reduce the spread of respiratory diseases.

[0006] The second objective of the utility model is to provide a microscope.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The utility model discloses an isolation device for a slit lamp microscope, comprising an isolation plate with a rectangular structure; a circular hole and an elongated opening are provided on the isolation plate, the circular hole is connected with the elongated opening, and the elongated opening extends from the edge of the circular hole to the long side of the isolation plate and passes through the long side of the isolation plate; the circular hole is used for clamping with the cylinder at the back of the microscope.

[0009] In the isolation device, preferably, protrusions are respectively provided on four peripheral edges of one side of the isolation plate, and the protrusions are integrally formed with the isolation plate.

[0010] In the isolation device, preferably, the edge of the circular hole is provided with a sponge edging.

[0011] In the isolation device, preferably, the edge of the elongated opening is provided with an edge-wrapped magnetic attraction structure.

[0012] In the isolation device, preferably, the isolation plate and the protrusion are respectively made of transparent materials.

[0013] The microscope described in the utility model comprises the above-mentioned isolation device for the slit lamp microscope.

[0014] The utility model adopts the above technical solution, which has the following advantages:

[0015] (1) The utility model can overcome the shortcomings of existing slit lamp microscopes, especially during the peak influenza season and the COVID-19 pandemic, and is conducive to blocking the transmission pathway, protecting both parties, and will not affect the observation of patients during the examination;

[0016] (2) The circular hole structure on the isolation plate in the utility model can be adjusted in size as needed to adapt to the size of the cylinder on the slit lamp microscope of different models. At the same time, the two sides of the upper slender opening are designed with an edge, and a magnetic structure is hidden inside. In this way, after the isolation plate is put on the cylinder, the two sides of the upper slender opening of the isolation plate can be tightly combined together due to the magnetic structure, and fixed on the slit lamp together with the circular structure below. At the same time, the entire panel will not have holes due to the slender opening;

[0017] (3) The utility model provides a bulge that forms a dam-like bulge on the isolation plate, wrapping the entire isolation plate. In this way, during the inspection, the droplets and exhaled air from the respiratory tract of both parties will not come into direct contact, thereby enhancing the protection of both parties.

[0018] (4) The utility model uses a soft sponge structure to wrap the circular hole in the middle of the isolation plate, which can increase the contact area when placed on the slit lamp and reduce the leakage when the circular hole and the cylinder are in contact. The diameter of the circular hole can be adjusted as needed;

[0019] (5) The isolation plate of the utility model is made of transparent material, which can provide isolation and protection without affecting the doctor's observation of the patient;

[0020] (6) The isolation plate of the utility model can be used not only as a protective device during slit lamp microscope inspection, but also can be applied to other instruments or scenes where the distance is relatively close and protection of both parties is required.
