Anti-suffocation pharyngeal airway tube

Abstract

The invention discloses an anti-suffocation pharyngeal airway tube which is made of a flexible medical silica gel material. The outer diameter of the airway tube is smaller than the size of the nasalcavity of a person, the airway tube (1) is of a straight tube structure, and when the airway tube (1) extends into the pharynx from the lower nasal meatus of the person, the airway tube (1) is arranged on the pharynx and supports the collapsed part of pharyngeal polyp. The airway tube can be inserted into the pharynx from the nostrils before a general anesthesia operation of a patient, even if thepolyp of the pharynx collapses during the operation of the patient, the patient can breathe smoothly due to the support of the airway tube, and the operation risk and trauma of tube cutting are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-suffocation pharyngeal airway. Background technique [0002] The upper airway of adults is the pharyngeal cavity, and its front and side walls are not supported by bony tissue. It is kept open by muscle tension on the pharyngeal cavity wall. When the patient is under anesthesia, the pharyngeal cavity can be narrowed to varying degrees due to muscle relaxation and the tongue falling backward. If the pharyngeal cavity is significantly narrowed, a hypopneic state is produced during inspiration due to rapid airflow through the uvula, tongue base, and epiglottis. When the muscles of the pharyngeal wall lose their tension completely, the pharyngeal polyps collapse, and the tongue completely falls back, forming a complete obstruction of the upper airway, that is, the collapse causes apnea syndrome, leading to apnea and suffocation. Intubation; but when the patient is u...

AI Technical Summary

Problems solved by technology

When the muscles of the pharyngeal wall completely lose their tension, the pharyngeal polyps collapse, and the tongue completely falls back, forming a complete obstruction of the upper airway, that is, the collapse causes apnea syndrome, leading to apnea and suffocation. Intubation; but when the patient is under general anesthesia, the accumulation of pharyngeal polyps will make it impossible to complete the intubation work. In this case, the trachea can only be cut to ensure smooth breathing. trauma and financial burden
