Portable visual laryngoscope

Abstract

A portable visual laryngoscope includes a handle, a laryngeal lens and a suction device. A camera is arranged at the end portion of the laryngeal lens. A display for display images taken by that camera is arranged on the handle. The laryngeal lens has a circular arc shape. One end of the laryngeal lens is connected with the handle, and the other end of the laryngeal lens is provided with a spatula, which is bent toward the inner side of the circular arc of the laryngeal lens. The suction device comprises a suction pipe, a hose and a portable negative pressure source. The suction pipe is arranged along the axial direction of the handle, and extends toward the end of the laryngeal lens. One end of the suction pipe is arranged at the lower end of the laryngeal lens, and the other end of the suction pipe is communicated with the portable negative pressure source through the hose. The portable negative pressure source is provided with a switch. The portable visual laryngoscope has the advantages of simple structure, simple and convenient operation and timely cleaning of foreign bodies in the oral cavity of patients in the laryngoscope observation room, matches with the spatula to expandthe observation field of vision and facilitates clearer detection of cameras, is convenient to operate, and has very broad application prospects.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a portable visual 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, and the viewing angle (field of view) of the laryngoscope is the key to the treatment, and the structure of the human larynx is complex, and the patient's larynx usually has thick phlegm, which is not convenient for the camera on the laryngoscope to observe , affecting vision. [0003] Therefore, the above problems should be considered and solved during the use and design of laryngoscopes. Contents of the invention [0004] In order to solve the above problems, the present invention provides a portab...
