Problems solved by technology

[0003] During use, because the tracheal wall inside the human body contains mucus or sputum, the sputum will be adsorbed around the camera during the insertion of the electronic laryngoscope, which will affect the camera's photographing effect. The existing device cannot timely capture the sputum. to clean up

Abstract

The invention discloses an electronic nasopharyngeal laryngoscope with a two-section preamplifier, which belongs to the field of medical instruments and comprises a first hose, a display device is fixedly connected to the top end of the first hose, a handle is fixedly connected to the bottom of the first hose, and a second hose is connected to the left side of the handle. The left end of the second hose is fixedly connected with a first shell, by arranging a camera, an LED lamp, a data line and a video amplifier, the device can shoot clearer pictures and transmit the pictures out, by arranging an adjusting device and a first rotating shaft, the camera can rotate by a small angle, and therefore a larger shooting view angle is obtained; by arranging a sputum inlet, an air suction pipe, a scraping plate and a handle, the device can clean the glass cover, sputum is prevented from being attached to the surface of the glass cover. Meanwhile, sputum in the nose and throat can be absorbed, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, and more specifically, relates to an electronic rhino-laryngoscope with a two-stage preamplifier. Background technique [0002] The electronic laryngoscope is generally composed of a camera, a hollow hard tube (or "connecting rod"), a handle and a control display module; the front end of the hollow hard tube is equipped with a camera, and the rear end is fixedly connected to the handle, and wires can be passed inside it. ; The rear of the handle is connected with a control display module. In the diagnosis and treatment process using the electronic laryngoscope, the electronic laryngoscope is generally used with a tracheal hose (or "tracheal intubation", or "tracheal tube", or "insertion tube"), that is, the hollow hard tube of the electronic laryngoscope Inserted into the endotracheal hose, the endotracheal hose is surrounded by a hollow hard tube with a camera and goes deep into the patient's t...
