Slit lamp fan structure and slit lamp

Abstract

The invention provides a slit lamp fan structure and a slit lamp, and relates to the technical field of medical instruments, the slit lamp fan structure comprises a fan assembly, a connecting pipe and an air bellow assembly; the air bellow assembly comprises an air outlet box and a connecting assembly, the radian of the arc-shaped side face, facing the forehead support, of the air outlet box corresponds to the radian of the forehead support of the slit lamp, an air outlet hole is formed in the bottom of the air outlet box and is opposite to a lens of the slit lamp, and water mist on the lens is removed through air blown out of the air outlet hole. Due to the fact that the radian of the side face of the air outlet box corresponds to the radian of the forehead support, the air outlet box is firmly fixed to the forehead support through the connecting assembly, air exhausted from the air outlet holes can effectively remove water mist on the lens, normal use of the slit lamp is guaranteed, air blown downwards from the air outlet holes can confront with breath diffused upwards from the mouth and the nose of a patient, and the lens is prevented from fogging. According to the slit lamp fan structure, the structure of an existing slit lamp does not need to be changed, the slit lamp fan structure only needs to be installed on the slit lamp, and the effect of preventing the lens from fogging can be achieved.

Description

technical field

[0001] The invention relates to the technical field of medical equipment, in particular to a slit lamp fan structure and a slit lamp. Background technique

[0002] Slit lamp microscope is a commonly used inspection method in ophthalmology. It is composed of a light source projection system and a magnification system. The focus and light source width can be adjusted to form an optical section to observe the condition of the external eye, ocular surface, anterior segment and anterior vitreous body. At the same time, the slit lamp microscope can also be attached with a gonioscope, a three-sided mirror, and a front mirror, etc., to cooperate with the inspection of the anterior chamber angle, the peripheral part of the retina, and the posterior vitreous body. During the examination, the examinee was asked to sit in front of the slit lamp with his chin resting on the jaw rest and his forehead resting on the forehead rest. When using gonioscopy and three-sided mirr...
