Laryngeal mask cannula for gastroscopy

Abstract

The invention discloses a laryngeal mask cannula for gastroscopy. The laryngeal mask cannula comprises a gastroscope catheter, a drainage cavity tube is fixedly installed on the outer surface of the upper end of the gastroscope catheter, a PC joint is fixedly installed at one end of the drainage cavity tube, a ventilation hole is formed in the outer surface of the upper end of the drainage cavitytube, and a suction hole is formed in the outer surface of the lower end of the gastroscope catheter; a catheter inner cavity and an inflation tube insertion hole are formed in the gastroscope catheter, the inflation tube insertion hole is formed in the lower portion of the catheter inner cavity, an inflation tube penetrates through the interior of the inflation tube insertion hole, and a single-cavity joint is fixedly installed at one end of the inflation tube. The laryngeal mask cannula has the advantages that through the arrangement of the drainage cavity tube and the suction hole, secretions generated in the gastroscopy process can be sucked and removed, and the occurrence of the phenomenon that a patient is choked and coughs due to the secretions generated in the gastroscopy process is avoided, so that the experience of using the esophageal trachea cannula is better.

Description

technical field [0001] The invention relates to a laryngeal mask intubation tube, in particular to a laryngeal mask intubation tube for gastroscopy, and belongs to the technical field of laryngeal mask intubation applications. Background technique [0002] During gastroscopy, it is necessary to insert the gastroscope catheter from the patient's pharynx and trachea into the patient's stomach. In the process of inserting the catheter, it is often necessary to use some medical equipment to relieve the pain of the examiner, such as using a laryngeal mask to insert the catheter into the patient's stomach. In the patient's throat and trachea, it can avoid damage to the throat and tracheal mucosa. [0003] However, the intubation tube on the existing laryngeal mask cannot absorb and clean up the secretions at the upper part of the esophagus, and there is a situation where the patient coughs due to the reflux of the secretions at the upper part of the esophagus, which brings certain...
