Disposable oropharynx pathway oxygen feeding mask

Abstract

The invention provides a disposable oropharynx pathway oxygen feeding mask which comprises a mask main body and a skin pad jointed to a port of the mask main body in an encircling manner, wherein the outer side of the mask main body is convex; the inner side of the mask main body is concave; a connecting tube head with an oxygen feed port is connected to the outer side of the mask main body; an oropharynx parichnos is connected to the edge of the oxygen feed port on the inner side of the mask main body; and the through hole of the oropharynx parichnos is communicated with the oxygen feed port. The oxygen feeding mask has the benefits that the advantages of a mask are maintained while obstruction caused by a tongue can be avoided during oropharynx ventilation, so that limited airflow can enter the airway of a patient directly, the supply quantity of gas is enlarged, the lungs of the patient can be expanded better, the consumption of oxygen can be reduced, the availability of breathing emergency aid can be improved, the possibility of warping is low, required airflow can be fed to the airway of the patient accurately, and the tongue and the teeth of a twitching patient can be prevented from being damaged. The oxygen feeding mask further has the advantages that the operation is simple and fast; the use is convenient; and the cost is low.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a disposable oropharyngeal route oxygen supply mask. Background technique [0002] No matter in the hospital, at the rescue scene or in other places with medical rescue equipment, when the patient has difficulty breathing, breathing stop or temporary hypoxia, the medical staff often prefers the oxygen mask connected to the powered respirator for emergency treatment. Therefore, Oxygen mask is one of the most important medical equipment in respiratory first aid. But the oxygen supply mask used at present is all concave hollow, outward convex arch, and the difference of various oxygen supply masks is only in size and material. When the patient is in a state of semi-consciousness, confusion, or convulsions caused by certain diseases, the patient's mouth is often closed and nasal secretions increase, which hinders the input of gas. At this time, the doctor will use a gag or a lower mou...

AI Technical Summary

Problems solved by technology

When the patient is in a state of semi-consciousness, confusion, or convulsions caused by certain diseases, the patient's mouth is often closed and nasal secretions increase, which hinders the input of gas. At this time, the doctor will use a gag or a lower mouth Pharyngeal airway and nasopharyngeal airway, and then use the mask to further supply oxygen to the patient, which will cause cumbersome operations and even cause the patient to be instantly hypoxic

And the simple oxygen mask also has the problem that it is not easy to fix
