Abstract
The invention relates to an air source air channel system of a breathing machine, which is communicated with a first air source and a second air source via air channels. The air source air channel system comprises a first one-way valve (CV4) and a second one-way valve (CV5), a bypass air channel of the first one-way valve (CV4) is communicated with a first air source passage, an input end of the first one-way valve (CV4) is communicated with the first air source via a first pressure reduction valve (REG1), a bypass air channel of the second one-way valve (CV5) is communicated with a second air source passage, an input end of the second one-way valve (CV5) is communicated with the second air source via a second pressure reduction valve (REG2), an output end of the first one-way valve (CV5) is communicated with an output end of the second one-way valve (CV5), and the first one-way valve (CV4) and the second one-way valve (CV5) realize output via the same pipe air channel. The air source air channel system of the breathing machine does not need an external air source, leads the breathing machine to have a continuous and stable third air source during working, is low in cost, is reliable, and does not need any extra service operation.
Description
Technical field
The present invention relates to gas circuit control, be specifically related to a kind of respirator source of the gas air-channel system, especially be applied in the medical electronics.
Background technology
As shown in Figure 1, traditional respirator source of the gas air-channel system comprises two sources of the gas of oxygen cylinder and compressed air, through air relief valve REG1 and REG2 separately and flow control valve PSOL1 and PSOL2 offer main gas circuit through hybrid chamber separately.When respirator is worked, use sometimes pure oxygen, sometimes use air, use simultaneously and regulate oxygen concentration as required sometimes.On the other hand, end expiratory positive pressure (PEEP) and other gas control air path part also need be stablized source of the gas, directly use oxygen cylinder and compressed air, certainly will can not guarantee the source of the gas supply under various working conditions.And if increase another road source of the gas and gas circuit, again can gas circuit cost and complexity, give simultaneously to use and also make troubles.
Summary of the invention
The technical issues that need to address of the present invention are, how a kind of respirator source of the gas air-channel system is provided, and need not increase provides the 3rd continual and steady source of the gas when external air source can be worked to respirator.
The above-mentioned technical problem of the present invention solves like this: make up a kind of respirator source of the gas air-channel system, gas circuit is communicated with first source of the gas and second source of the gas, it is characterized in that, this source of the gas air-channel system comprises:
First check valve, other gas circuit are communicated with the first source of the gas path, and input is communicated with first source of the gas through first air relief valve;
Second check valve, other gas circuit are communicated with the second source of the gas path, and input is communicated with second source of the gas through second air relief valve;
The outfan of the outfan of first check valve and second check valve is communicated with and exports through same pipeline gas circuit.
According to respirator source of the gas air-channel system provided by the invention, the first source of the gas path also comprise string on its outfan, control first proportioning valve of its output flow; The other gas circuit of first check valve is communicated with on the pipeline between first air relief valve and first proportioning valve.
According to respirator source of the gas air-channel system provided by the invention, the second source of the gas path also comprise string on its outfan, control second proportioning valve of its output flow; The second check valve bypass is communicated with on the pipeline between second air relief valve and second proportioning valve.
Respirator source of the gas air-channel system provided by the invention utilizes the respirator first and second external air source work characteristics, and prior art has following advantage relatively:
1, need not increase external air source and inner pressure relief valve;
The 3rd continual and steady source of the gas is arranged when 2, working;
3, cost is low, reliable and need not any extra use operation.
Description of drawings
Further the present invention is elaborated below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is traditional respirator source of the gas gas circuit structure sketch map;
Fig. 2 is the respirator source of the gas gas circuit structure sketch map of the specific embodiment of the invention.
The specific embodiment
The respirator source of the gas air-channel system of the specific embodiment of the invention, gas circuit structure is as shown in Figure 2, comprises the first check valve CV4, and the other gas circuit of input is communicated with first gas source pipe between the first air relief valve REG1 and the first proportioning valve PSOL1; The second check valve CV5, the other gas circuit of input is communicated with through second gas source pipe between the second air relief valve REG2 and the second proportioning valve PSOL2; The outfan of the outfan of the first check valve CV4 and the second check valve CV5 is interconnected and exports to other parts of respirator through same pipeline gas circuit and use.
The by-pass valve control of the respirator source of the gas air-channel system of the specific embodiment of the invention selects the gas operation principle to be automatically: in the gas source gas circuit of dual gas supply or many sources of the gas air feed; Can select a kind of source of the gas or multiple source of the gas to use simultaneously during work; But the part of back control gas needs continuous flow control; And the control gas of branch road can't Selective Control under the gas source, therefore on the source of the gas of each branch road, increases a check valve, and is mixed in a gas circuit the source of the gas of many sources of the gas; Use the made gas of check valve can not reverse flow in addition, guarantee that gas circuit control is normal.
The above is merely preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
