Medical oral-nasal double-channel oxygen inhalation breathing mask

Abstract

The invention discloses a mask which comprises a mask body. An oxygen supply pipe connector and air bags are arranged on the mask body, an auxiliary connector is arranged on the mask body and is positioned below the oxygen supply pipe connector, closed switching connectors are arranged on the auxiliary connector and include a first closed switching connector or a second closed switching connector, a first through hole is formed in the top of the first closed switching connector, a silicone cap is arranged o the top of the first closed switching connector, and a second through hole is formed in the top of the second closed switching connector. The mask has the advantages that the closed switching connectors can be inserted in the periphery of the auxiliary connector when the mask is used, an oxygen supply pipe can be connected with the oxygen supply pipe connector, the silicone cap can be opened, and accordingly tracheal cannulas or bronchofiberscope can be conveniently inserted into the nasal cavities of patients via the through holes without stopping oxygen supply when oxygen is about to be supplied to the patients; the closed switching connectors can be inserted into the oxygen supply pipe connector, the oxygen supply pipe can be inserted in the periphery of the auxiliary connector, the silicone cap can be opened, and accordingly the tracheal cannulas or the bronchofiberscopes can be conveniently inserted into the oral cavities of the patients via the through holes without stopping oxygen supply when the oxygen is about to be supplied to the patients.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a medical breathing mask for supplying oxygen through oral and nasal dual channels. Background technique [0002] Nowadays, breathing masks are often used when performing operations on critically ill patients. When using a breathing mask, first fit the breathing mask to the patient's nose or mouth, and then connect the oxygen supply tube to the oxygen supply tube connector on the main body of the mask. Connect, so that oxygen can be supplied to the patient for assisted breathing. [0003] The Chinese patent application number 201320057589.X discloses a breathing mask (see attached figure 1 ), which includes a mask main body, a ventilation interface provided on the mask main body, and an openable closed operation port on the mask main body for insertion of intubation tubes or instruments. The respiratory mask can perform tracheal intubation while maintaining assisted...

AI Technical Summary

Problems solved by technology

[0004] When inserting a bronchoscope or gastrofiberscope into a patient, the operation through the mouth or through the nose is generally selected according to the actual situation. It is impossible for the medical personnel to conveniently choose whether to insert the endotracheal tube through the patient's mouth or through the nose according to the actual situation; at the same time, when the patient is using a breathing mask, the patient's respiratory rate and tidal volume are two very important indicators. When the respiratory rate and tidal volume are too low, the medical staff should take timely measures, but the breathing mask itself does not have the function of prompting the patient's breathing condition, which makes the medical staff not timely grasp the patient's breathing condition, and cannot provide oxygen for the patient. The situation of respiratory depression is found before the saturation drops; and the above-mentioned breathing mask realizes the insertion of intubation or instrument through the openable closed operation port, but when using the breathing mask to supply oxygen to the patient, the openable The closed operation port cannot be completely closed, and there is a problem of unsatisfactory sealing, so it is not possible to simply supply oxygen with positive pressure
