Supraglottic upper airway device with non-invasive endotracheal intubation and positive pressure ventilation

Abstract

The invention discloses a supraglottic upper airway device allowing non-invasive endotracheal intubation, and a respiratory tract management device capable of positive pressure breathing and spontaneous breathing. The supraglottic upper airway device includes a piping system, an airbag, and a base. The piping system comprises a ventilation duct arranged in parallel and an optional optical fiber mirror duct, the ventilation duct is a hollow duct with both ends open, and the bottom wall of the distal end of the ventilation duct is provided with an extension sheet of the ventilation duct. The base part comprises a base plate and a drainage tube ring, wherein the drainage tube ring is composed of an esophageal drainage tube and a second drainage tube. The esophageal drainage tube and the second drainage tube are arranged in parallel with the duct system. The invention provides a simple and easy-to-use upper glottic respiratory tract device and a non-invasive tracheal intubation.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and relates to a supraglottic airway device with non-invasive tracheal intubation and positive pressure ventilation. In addition, the present invention provides a way to diagnose and treat diseases of the vocal cords and trachea near the glottis. Background technique [0002] In the past few decades, traditional metal laryngoscopes and various video laryngoscopes used in the past ten years are often used for tracheal intubation of patients. When patients need tracheal intubation, medical staff often need deep sedation and general anesthesia. The intubation task can be completed under the condition of The use of the metal piece of the laryngoscope will cause many obvious hazards to the patient, such as tooth damage, respiratory soft tissue damage, etc. In addition, for patients with neck injuries, the metal piece of the laryngoscope is difficult to avoid moving during the insertion process Th...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a supraglottic airway device capable of non-invasive tracheal intubation and positive pressure ventilation. Or perform positive pressure artificial mechanical respiration, which can be referred to as positive pressure breathing or positive pressure ventilation, and provide a non-invasive endotracheal intubation through the upper glottic airway device, which is easy to use and can be used as a guide tube for difficult airway intubation , can be "blind insertion" or intubation under video with the use of various fiberscopes that have been used clinically today, which can improve the success rate of difficult intubation
