The specific embodiment
Below in conjunction with accompanying drawing, this utility model medical breathing machine gas mixer is described in further detail.
As shown in Figure 1 and Figure 2, this utility model medical breathing machine gas mixer is fixed on medical breathing machine inside, is placed in respirator air intake assembly rear end, and centre can be provided with pressure maintaining valve, flow-regulating proportional valve and flow transducer.
Respirator air intake assembly oxygen and air out entered successively in the one-level hybrid chamber 2 in air inlet module 1 and carried out elementary mixing by two air inlets 3 on air inlet module 1 respectively, for further gas mixing is more even, between air inlet 3 and one-level hybrid chamber 2, add cushion chamber 4, now not yet mix homogeneously of gas.
Elementary mixed gas enters buffer module 5 by the air flue 7 of buffer module 5 central authorities, in the secondary hybrid chamber 6 of buffer module 5, carries out secondary mixing.
In buffer module 5, have inducing QI leaf fan 8, mist enters and under the effect of inducing QI leaf fan 8, does rotating Vortex after buffer module 5 and flow, and has effectively increased gas incorporation time, makes to mix more evenly, fully, and gas now elementary mixing is even.
Even mixed gas backs down valve body diaphragm 12, enters by the array waist hole 10 in check valve sheet 9 module 14 of giving vent to anger, and makes, so only need very little impulse force can back down valve body diaphragm 12 because valve body diaphragm 12 adopts thin rubber.
The little irregular waist of the outer imperial palace hole that array waist hole 10 in check valve sheet 9 is circular array maximizes venthole area in the situation that guaranteeing instructions for use.
Check valve sheet 9 is the indent conical surface with the binding face of valve body diaphragm 12, has increased the contact area of mist and valve body diaphragm 12, makes gas more easily back down valve body diaphragm 12 and enters the module 14 of giving vent to anger, and has also increased further gas outlet 16 areas.
There is heavy stand 11 at check valve sheet 9 indent conical surface cylindrical places, valve body diaphragm 12 sinks in check valve sheet 9 completely, gas in the module of giving vent to anger 14 in outlet chamber 15 is more difficult for entering the gap between valve body diaphragm 12 and check valve sheet 9, has more effectively stoped mist backflow.
The module of giving vent to anger 14 is provided with concentration sensor interface 17 and other various expansion interfaces 18, and the outlet side of the module of giving vent to anger 14 can be processed into different forms and be met different instructions for uses, can directly connect the tapered of corrugated tube as being processed into, maybe can connect the irregular type with sealing ring 19 grooves of elbow bend etc.
Below the preferred embodiment of this utility model having been created illustrates, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to this utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
