Diffuse illumination method: can roughly check the anterior tissues such as conjunctiva, cornea and sclera; direct black spot illumination method: can carefully observe the lesions in the illuminated area; posterior illumination method: assist the light reflected by the posterior tissue to inspect the anterior tissue of the eye For examination of transparent tissues; specular reflection illumination method; limbal spectroscopic illumination method; indirect illumination method.
The digital slit lamp can be dynamically observed using a computer, with high resolution, and can quickly capture the conditions in the patient's eyes. The market launch of the digital slit lamp not only requires medical equipment, but also brings more convenience to patients. This makes the clinical significance of digital slit lamps even more important.
The slit lamp is mainly used for inspection of the eyes. It can be said that the slit lamp is also a slit lamp microscope. The slit lamp is actually the same as its name. This lamp illuminates the eyes through a slit, and this narrow light source is a light knife. When this lamp is irradiated on the eyes, it will form an optical section and you can see the eyes The situation of each part.
In fact, the cost of the inspection of the slit lamp is the same as that of all medical inspections. It is determined by the local price bureau, and it is also determined based on the comprehensive analysis of the medical equipment conditions of the hospital. The cost of medical equipment is 100-500 yuan. In some hospitals with good medical conditions, the cost is higher.
Slit lamp is a very important instrument for examining ophthalmology. The slit lamp microscope is composed of an illumination system and a binocular microscope. It can not only observe the surface lesions very clearly, but also adjust the focus and the size of the light source to make it an optical section, so that the lesions of the internal tissues can See clearly.
There are six ways to use the slit lamp, but the most common are the diffused light irradiation method, direct focus irradiation method, and rear reflective irradiation method.
Slit lamp irradiation methods can generally be divided into six types: direct irradiation method, indirect irradiation method, rear back light method, moving light irradiation method, specular back light irradiation method, and limbal spectroscopic irradiation method.
The main methods for the use of slit lamp lighting debugging are: oblique illumination method, reflective method, back illumination method, diffused light illumination method, and adjustment of the diaphragm.
Should be placed in a well-ventilated, dry environment. The optical lenses must be kept clean. Optical lenses avoid contact with other parts of the human body. The condenser wipes the dust off with a duster. The outer part of the proud shaft Killing on the sports base is often wiped and lubricated. Tighten the fastening bolts when moving. Put on dust-proof leather immediately after using the instrument.
Slit lamp image system is a slit lamp image processing system used in conjunction with a slit lamp microscope. The workstation can receive images under the microscope to achieve image display, acquisition, and medical record management. The software design is flexible. The desired image can be acquired at any time. Can capture and save key areas of the image. You can add important image data from the outside. You can also record the acquired images.
The hand-held slit lamp is actually the same in function as the traditional table-type slit lamp. Both are a kind of inspection equipment commonly used in ophthalmology. The hand-held slit lamp is mainly due to its small size and relatively easy operation when picked up. Convenient, it can be used for lighting just by holding it in your hand, so it is called a handheld slit lamp.
The basic sequence of the slit lamp examination from the outside to the inside is: eyelid-edge of eyelid-eyelashes-lacrimal device-eyelid conjunctiva-bulbar conjunctiva-conjunctival sac-limbus cornea-sclera-cornea-anterior chamber-anterior chamber angle-iris -Pupil-posterior chamber-lens, right eye first and left eye. On average, each eye was examined for 120 seconds during screening, and further examinations were performed if there were specific problems.
It should be placed in a ventilated, dry room with a humidity not exceeding 50%. The lenses are often cleaned. Avoid contact with the lens or hands. You can remove the lamp cover and lamp holder, and use a dust pen to dust the condenser lens. The outer part of the sports base is often wiped and lubricated. Take care to prevent the guide rail from falling when the portable slit lamp is moved. After use, put on dustproof leather in time.
The slit lamp is mainly composed of a slit lamp and a microscope. In order to allow the slit light source to illuminate various parts from different angles, the slit lamp and microscope need to have sufficient swing angles before they can be used. The crack must be imaged on the vertical plane of the center of the circle, and the microscope is focused on the vertical plane of the center of the circle.
When using a slit lamp, there are mainly the following methods: oblique illumination method, reflective method, back-illuminated method, and aperture adjustment method.
Digital Wide Field ™, an upgraded version of the classic 90D, has a wider field of view, can minimize distortion and reflection, and has high-resolution image quality. The same effect can be achieved when passing through small pupils. || Super Pupil? XL, can get the best small pupil observation effect during the examination, can perform small pupil full retinal examination, which is very suitable for diabetic patients with dilated pupils.
The full name of the slit lamp microscope is a slit lamp microscope, which is the most frequently used optical device in ophthalmology.
