Face mask structure

Abstract

The invention discloses a face mask structure. The face mask structure comprises a face mask, a reversing valve is arranged at the upper part of the face mask, a fixing hole is formed in the lower part of the face mask, an oxygen connecting pipe is arranged on one side of the reversing valve, an anesthesia connecting pipe is arranged on the other side of the reversing valve, switches are arranged on the oxygen connecting pipe and the anesthesia connecting pipe, and the face mask and the fixing hole are formed integrally during being manufactured. The switches are used for controlling opening or closing of the oxygen connecting pipe and the anesthesia connecting pipe, and the reversing valve is used for forming a communicating way between the anesthesia connecting pipe and the face mask or used for forming a communicating way between the oxygen connecting pipe and the face mask. The face mask is transparent and visible, an oral-nasal protecting mask made of soft plastic is wrapped in the face mask. The face mask structure is simple in structure and convenient to use and has the switching function of oxygen and anesthetic gases.

Description

Technical field: [0001] The invention relates to medical equipment, in particular to a mask structure. Background technique: [0002] Inhalation of general anesthetic is one of the commonly used anesthesia methods in clinical rescue. This anesthesia method often uses a breathing mask, and its main function is to input anesthetic gas into the patient's body before and during the operation. Improvements to this mask structure in the prior art mostly focus on size and material, but cannot solve the problem of rapidly switching the input of oxygen and anesthetic gas. In some emergency operations, the anesthesia gas is injected before the operation, and after the patient enters the general anesthesia state, the anesthesia gas input tube is pulled out, and the oxygen tube is inserted into the mask; during the operation, when gas anesthesia is required again, the It is necessary to unplug the oxygen tube. After giving anesthesia gas according to the patient's needs, insert the ...

Improvements to this mask structure in the prior art mostly focus on size and material, but cannot solve the problem of quickly switching the input of oxygen and anesthetic gas

Now in some emergency operations, anesthesia gas is injected before the operation, and after the patient enters a state of general anesthesia, the anesthesia gas input tube is pulled out, and then the oxygen tube is inserted into the mask; during the operation, when gas anesthesia is required again, It is necessary to unplug the oxygen tube. After giving anesthesia gas according to the patient's needs, insert the oxygen tube into the mask. Such frequent operations are cumbersome, and each insertion and removal may easily cause the displacement of the mask, resulting in poor airtightness. Even cause anesthesia gas leakage
