Closed ventilation type oropharyngeal airway

Abstract

A closed ventilation type oropharyngeal airway comprises an airway breathing circuit mask connecting portion and an oropharyngeal airway, and is characterized in that a connecting plug is reserved at the lower end of the airway breathing circuit mask connecting portion, is hollow and cylindrical and can be closely connected with an oropharyngeal airway connecting hole, a hollow middle rectangle is arranged on the connecting plug, a connecting seat is mounted at the upper end of the airway breathing circuit mask connecting portion, is hollow and cylindrical and can be connected with a circuit mask of a breathing machine to realize closed ventilation, a front section of the oropharyngeal airway is a bent arc and is hollow, the outer surface of the front section of the oropharyngeal airway is elliptical, a rear section of the oropharyngeal airway is straight and hollow, the outer surface of the rear section of the oropharyngeal airway is elliptical, elliptical fixed wings are arranged on the top of the oropharyngeal airway, a circular connecting hole is arranged between the fixed wings, and closed ventilation type oropharyngeal airways can have large, middle and small sizes of 10cm, 8cm and 7cm respectively according to the different linear lengths of corresponding oropharyngeal airways. The closed ventilation type oropharyngeal airway overcomes technical shortcomings of an existing clinical oropharyngeal ventilation device, and is an oropharyngeal ventilation device capable of being connected with anesthetic masks and breathing machines by pipelines to realize closed ventilation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an oropharyngeal ventilator that can be connected to the pipeline of an anesthesia mask ventilator to realize manual or mechanical ventilation in the airtight state of a patient whose tongue falls backward, the airway is blocked, and the breathing stops. Background technique [0002] Patients with respiratory depression, airway obstruction, and tongue drop usually need oropharyngeal ventilation devices to solve breathing problems. At present, the ventilation devices commonly used in the medical field mainly include tracheal intubation and laryngeal mask ventilation catheters. During the use of endotracheal intubation, patients often need moderate muscle relaxation conditions, so the timing of manual or mechanical ventilation is often affected by muscle relaxation, and endotracheal intubation requires specialized doctors to use laryngoscopes. The technical requirements of medical st...

AI Technical Summary

Problems solved by technology

During the use of endotracheal intubation, patients often need moderate muscle relaxation conditions, so the timing of manual or mechanical ventilation is often affected by muscle relaxation, and endotracheal intubation requires specialized doctors to use laryngoscopes. The technical requirements of medical staff are relatively high, and tracheal intubation often occurs because a problem in a certain link affects the treatment result and the timing of rescue; during the use of the laryngeal mask ventilation catheter for patients, due to the great individual differences in the anatomical structure of the patient's throat cavity, It is easy to cause its airtight instability, and the laryngeal mask ventilation catheter is expensive, and its use has been limited because of its price

At present, the oropharyngeal airway is also used for oropharyngeal ventilation, but the existing oropharyngeal airway cannot achieve artificial or mechanical ventilation in a closed state during the use of the patient, and its use effect and scope are limited
