Description

Video laryngoscope with decontamination device

Technical field:

The invention relates to a medical device, in particular to a video laryngoscope with a decontamination device.

Background technique:

In 2000, Canadians invented the video laryngoscope. The principle is that a camera is set on the front end of the laryngeal lens. The camera collects airway images, and transmits the collected airway images to the video display on the laryngoscope handle through the data line. Observe the airway image. Compared with the traditional laryngoscope, the video laryngoscope has a wider field of view, which makes it easier for the operator to perform tracheal intubation. But its fatal flaw is that when emergency tracheal intubation is performed in the rescue of critically ill patients, even a drop of blood, secretions in the mouth, smeared on the camera, or fog condensed on the camera, can completely block the airway of the video laryngoscope. The image makes the video laryngoscope immediately lose the function of observing the airway image, and it will delay the rescue in an emergency.

Summary of the invention:

In order to make up for the technical defects of the above-mentioned video laryngoscope, the purpose of the present invention is to provide a video laryngoscope with a decontamination device.

The present invention is implemented by the following technical solutions: a video laryngoscope with a decontamination device, which includes a laryngoscope handle and a laryngoscope lens, a light source and a camera are arranged on the top of the laryngoscope lens, and the laryngoscope handle is provided with A display screen connected to the camera; a decontamination link is hinged on the outer wall of the laryngeal lens; one end of the decontamination link near the front end of the laryngeal lens is provided with friction with the lens surface of the camera Decontamination scraper in contact; a decontamination lever is provided at one end of the decontamination link near the end of the laryngeal lens.

Preferably, a shaft sleeve is fixedly provided on the outer wall of the laryngeal lens, and a rotating shaft correspondingly inserted into the shaft sleeve is provided on the decontamination connecting rod.

Preferably, a reset torsion spring is sleeved on the rotating shaft in the shaft sleeve.
