Face mask structure

Abstract

The invention discloses a mask structure, including a mask, wherein, the upper part of the mask is provided with a reversing valve, the lower part is provided with a fixing hole, one side of the reversing valve is provided with an oxygen connecting pipe, and the other side is provided with an anesthesia connecting pipe, A switch is arranged on the oxygen connecting pipe and the anesthesia connecting pipe, and the mask and the fixing hole are integrally formed during manufacture. The switch is used to control the opening or closing of the oxygen connecting tube and the anesthesia connecting tube, and the reversing valve is used to form a passage between the anesthesia connecting tube and the mask or to form a passage between the oxygen connecting tube and the mask. The mask is transparent and visible, and a mouth and nose shield made of soft plastic is wrapped inside it. The invention has the advantages of simple structure, convenient use and the switching function of oxygen and anesthetic gas.

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
