Multi-source end-tidal CO2 monitoring auxiliary visual laryngeal mask

Abstract

The invention belongs to the technical field of anesthesia medical CO2 monitoring auxiliary devices, and specifically relates to a multi-source end-tidal CO2 monitoring auxiliary visual laryngeal mask. The laryngeal mask includes a main tube, a capsule body, an inner plate and a camera; the capsule body is bonded at the bottom of the main tube; and the inner plate is bonded on the front sidewall of the capsule body. Through the combination utilization of fittings, the laryngeal mask can observe the internal of a patient by coordinating the camera and a display screen; observation can be performed on internal environments during the using of the laryngeal mask; the laryngeal mask is high in intubation accuracy, short in time consumption and unable to cause subsidiary-injury of the patient;after the entering of the capsule body, the air delivery of the main tube can be performed through a main hole and auxiliary holes with inner meshes, so that the uniform dispersing effects of air canbe increased, the laryngeal mask can be good in comfortability, and the disadvantages of choking and difficult breathing caused by concentrated and fast air flow cannot be caused; and after atropine drugs are arranged in a top capsule, the drugs can be released through drug-releasing holes during using, so that the formation of oral secretions can be inhibited.

Description

technical field [0001] The present invention relates to anesthesia medical CO 2 The technical field of monitoring auxiliary devices, specifically a multi-source end-exhalation CO 2 Monitoring aid visual laryngeal mask. Background technique [0002] Tracheal intubation is the most effective and reliable method to establish an artificial airway, and it is an essential technique for general anesthesia and emergency recovery. [0003] The traditional intubation method is to use a direct laryngeal mask, but the airway conditions of the patients vary widely. For patients, it is often very difficult to directly insert the laryngeal mask. The failure rate of the first intubation is high, and repeated attempts are required, which takes a long time and is likely to cause secondary injury to the patient. 2 The method of monitoring to determine the position of the endotracheal tube in the body and facilitate adjustment can improve efficiency and improve the above problems.
