Lateral oxygen supply and sputum suction nasopharyngeal airway

Abstract

The invention provides a lateral oxygen supply and sputum suction nasopharyngeal airway. The lateral oxygen supply and sputum suction nasopharyngeal airway comprises a nasopharyngeal airway tube, an oxygen supply and sputum suction extending tube and a built-in oxygen supply and sputum suction tube which is arranged inside the nasopharyngeal airway tube, wherein one end of the built-in oxygen supply and sputum suction tube is provided with an outlet of the built-in oxygen supply and sputum suction tube; the other end of the built-in oxygen supply and sputum suction tube is connected with one end of the oxygen supply and sputum suction extending tube through an externally arranged interface of the built-in oxygen supply and sputum suction tube; the other end of the oxygen supply and sputum suction extending tube is connected with one end of an oxygen supply and sputum suction joint; and the tube wall of the nasopharyngeal airway tube is internally wrapped by breaking prevention steel wires. The lateral oxygen supply and sputum suction nasopharyngeal airway has the advantages of having two functions of oxygen supply and sputum suction; ensuring sufficient oxygen supply and good oxygen inhalation effect during the oxygen supply; ensuring sufficient sputum suction, enabling a respiratory tract of a patient not to be stimulated and ensuring that the patient can breathe normally during the sputum suction; and guaranteeing that the nasopharyngeal airway tube is not deformed during insertion and after insertion of the lateral oxygen supply and sputum suction nasopharyngeal airway due to the wrapped breaking prevention steel wires and preventing complications caused by affected ventilation due to the previous pure soft plastic which is easy to break.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a side-type oxygen supply and sputum suction nasopharyngeal airway. Background technique [0002] All kinds of critically ill patients will have dyspnea, breathlessness and shortness of breath in the early or late course of the disease; after the end of general anesthesia in the operation, the patient may also have different degrees of breathing disorders due to the tongue falling behind; excessive obesity and medical Changes in some special examination positions will cause respiratory abnormalities. If not dealt with in time, it will lead to hypoxia and suffocation of the patient. For this reason, clinical respiratory management is very important. [0003] At present, such patients are treated with pressurized oxygen by breathing masks, and oxygen inhalation is assisted by breathing masks, all of which require expensive medical equipment, such as ventilators and anesthe...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a side-type oxygen supply and sputum suction nasopharyngeal airway, which solves the problem of insufficient oxygen supply in the existing nasopharyngeal airway, poor oxygen inhalation effect, insufficient sputum suction or stimulation of the patient's respiratory tract, causing the patient to Difficulty breathing, airway complications, etc.
