Abstract
This utility model provides a kind of one-way air inlet anti-leak anaesthetic mask, comprise interface, it is characterized in that: described interface connects spirally inlet air passage, described spirally inlet air expanding channels admission line, air inlet is provided with in described admission line, the side of described air inlet is provided with filter element, venting channels is provided with in described filter element, linking springs on described filter element, the other end of described spring be connected with described air inlet with the use of baffle plate, described admission line is fixed on face shield, and described face shield surrounding is provided with silica gel mouth.Spirally inlet air passage of the present utility model can cushion and enter air-flow, and ensure stable gas pressure, normal condition, air inlet both sides air pressure balance, baffle plate blocks air inlet under the action of the spring, realizes sealing.
Description
Technical field
This utility model relates to medical instruments field, specifically, relates to a kind of one-way air inlet anti-leak anaesthetic mask.
Background technology
Existing anaesthetic mask cannot prevent anesthetic gases from leaking, the easy anaesthetic effect that affects easily brings impact to people around, existing anaesthetic mask cannot filter in exit, likely inner impurity is taken out of, existing anaesthetic mask cannot prevent stream in outside air, can not ensure internal gas quality.This is the deficiencies in the prior art part.
Summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of one-way air inlet anti-leak anaesthetic mask, and buffering enters air-flow, ensures stable gas pressure, prevents foreign material in gas from entering human body.
This utility model adopts following technical scheme to realize goal of the invention:
A kind of one-way air inlet anti-leak anaesthetic mask, comprise interface, it is characterized in that: described interface connects spirally inlet air passage, and described spirally inlet air expanding channels admission line, is provided with air inlet in described admission line, the side of described air inlet is provided with filter element, be provided with venting channels in described filter element, linking springs on described filter element, the other end of described spring be connected with described air inlet with the use of baffle plate, described admission line is fixed on face shield, and described face shield surrounding is provided with silica gel mouth.
As the further restriction to the technical program, the side of described air inlet is provided through the expansion plate of described admission line, and the outside of described expansion plate is enclosed with rubber layer.
Compared with prior art, advantage of the present utility model and good effect are: spirally inlet air passage of the present utility model can cushion and enter air-flow, ensure stable gas pressure, normal condition, air inlet both sides air pressure balance, baffle plate blocks air inlet under the action of the spring, realizes sealing.When starting ventilation, air-flow backs down baffle plate, and spring is compressive state, realizes air inlet.Filter element filtering gas, prevents foreign material in gas from entering human body.Expansion plate for regulating the air inlet size of air inlet, thus regulates the air inflow entering face shield, and silica gel mouth and face fit tightly, and prevents from flowing in outside air and gas outflow guarantee internal gas quality in face shield.

Fig. 3 is the schematic diagram of filter element of the present utility model, air inlet, spring and baffle plate air-suction state.
In figure, 1, spirally inlet air passage, 2, interface, 4, face shield, 5, silica gel mouth, 6, air inlet, 7, filter element, 8, venting channels, 9, spring, 10, baffle plate, 11, admission line 12, expansion plate.
Detailed description of the invention:
Below in conjunction with embodiment, further illustrate this utility model.
See Fig. 1-Fig. 3, this utility model comprises interface 2, interface 2 connects anesthetic gases providing device, described interface 2 connects spirally inlet air passage 1, described spirally inlet air passage 1 connects admission line 11, air inlet 6 is provided with in described admission line 11, the side of described air inlet 6 is provided with filter element 7, venting channels 8 is provided with in described filter element 7, linking springs 9 on described filter element 7, the other end of described spring 9 be connected with described air inlet 6 with the use of baffle plate 10, described admission line 11 is fixed on face shield 4, and described face shield 4 surrounding is provided with silica gel mouth 5.
The side of described air inlet 6 is provided through the expansion plate 12 of described admission line 11, and the outside of described expansion plate 12 is enclosed with rubber layer (not shown).Extension rubber 12 is fastened on the sidewall of admission line 11, and one is play the effect self fixed and seal, and two is move up and down the openings of sizes that can regulate air inlet 6 by expansion plate, thus regulates the air inflow entering face shield.
Spirally inlet air passage 2 of the present utility model can cushion and enter air-flow, and ensure stable gas pressure, normal condition, air inlet 6 both sides air pressure balance, baffle plate 10 blocks air inlet 6 under the effect of spring 9, realizes sealing.When starting ventilation, air-flow backs down baffle plate 10, and spring 9, in compressive state, realizes air inlet.Filter element 7 filtering gas, prevents foreign material in gas from entering human body.Expansion plate 12 for regulating the air inlet size of air inlet 6, thus regulates the air inflow entering face shield 4, and silica gel mouth 5 and face fit tightly, and prevents from flowing in outside air and gas outflow guarantee internal gas quality in face shield.
