Laryngoscope

Abstract

The invention discloses a laryngoscope. The laryngoscope comprises a handle and a laryngoscope blade, wherein the handle and the laryngoscope blade form an L shape, a camera is arranged at the end part of the laryngoscope blade, a display which is used for displaying images photographed by the camera is arranged on the handle, a regulating mechanism which is used for regulating the depth of the laryngoscope blade in a throat is arranged between the handle and the laryngoscope blade and comprises a regulating gear and a gear rack, a regulating window and a gear rack accommodating groove are formed in the handle, the regulating gear is rotatably arranged in the regulating window, the gear rack accommodating groove communicates with the regulating window, one end of the gear rack is fixedly connected with the laryngoscope blade, the other end of the gear rack is arranged in the accommodating groove in a sliding manner, and the gear rack is engaged with the regulating gear. The laryngoscope is simple in structure, the position of the laryngoscope blade in the throat can be fine-adjusted up and down, and thus, the laryngoscope can more efficiently work at throats of patients.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laryngoscope. Background technique [0002] Due to the deep position of the larynx and the complex physiological structure, it is impossible to directly see it. When checking the larynx, it is necessary to use a laryngoscope for inspection. The laryngoscope generally consists of two parts: a handle and a laryngoscope. The larynx is directly observed, but the structure of the human larynx is complicated, and thick phlegm usually accumulates in the larynx of the patient, which is not convenient for the camera on the laryngoscope to observe the camera, and the sputum is also difficult to clean up. Due to the presence of foreign objects in the larynx, people will have a swallowing reaction or retch, which will make the laryngoscope go deeper into the larynx or withdraw from the original position, thus affecting normal observation, prolonging the examination time and inc...

Problems solved by technology

[0002] Due to the deep position of the larynx and the complex physiological structure, it is impossible to directly see it. When checking the larynx, a laryngoscope is needed. The laryngoscope generally consists of a handle and a laryngoscope. The handle is equipped with a monitor, which is convenient for patients. The larynx is directly observed, but the structure of the human larynx is complex, and thick phlegm usually accumulates in the patient's larynx, which is not convenient for the camera on the laryngoscope to observe, and the sputum is also difficult to clean up. Due to the presence of foreign objects in the larynx, people will have a swallowing reaction or retch, which will make the laryngoscope go deeper into the larynx or withdraw from the original position, thus affecting normal observation, prolonging the examination time and increasing the pain of the patient
