Description
Technical field
The present invention relates to a kind of gas with various rapid mixing that makes and install uniformly, can be used for medical breathing machine and carry out the mixing of sky oxygen Quick uniform, make oxygen concentration sensor reflect more fast, truly oxygen concentration, meet machine requirement is set, belong to gas control field.
Background technology
Thereby existing medical breathing machine is realized empty oxygen rapid mixing, make oxygen concentration sensor reflect more fast, truly oxygen concentration, meet respirator and requirement is set mainly by two kinds of modes, realizes:
1) use empty oxygen mixer, oxygen and air access respectively empty oxygen mixer, when respirator regulates oxygen concentration, by empty oxygen mixer, oxygen concentration is controlled, make outlet side oxygen concentration reach machine requirement is set, but empty oxygen mixer is expensive, the empty oxygen mixer price of least significant end is also wanted several ten thousand yuan.By this device, when respirator regulates oxygen concentration, only need to be by regulating proportioning valve that the required air mass flow of this concentration and oxygen flow are accessed to this device, by fast, evenly mixing of this device, outlet side oxygen concentration sensor records numerical value and is actual concentration numerical value, be that machine arranges numerical value, low side proportioning valve can meet instructions for use, cheap.
2) do not use empty oxygen mixer, but need to set up high-end Platform of hardware, thereby use the mode of feeding back ceaselessly to regulate air and oxygen flow that oxygen concentration is reached, requirement is set.When respirator regulates oxygen concentration, required air mass flow and oxygen flow arrive oxygen concentration sensor place, because gas does not also fully mix, the numerical value that oxygen concentration sensor records is instant numerical value, this numerical value and numerical value is set has deviation, this deviation feeds back to Platform of hardware, by platform, ceaselessly regulate proportioning valve to change air mass flow and oxygen flow, thereby sensor values is moved closer to, numerical value is set, the method response time is slow, control difficulty is high, regulates platform to require high.

The specific embodiment
Below in conjunction with accompanying drawing, medical gas mixing arrangement of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, medical gas mixing arrangement of the present invention 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 gas mix homogeneously not yet.
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 to be done rotating Vortex after buffer module 5 and flows under the effect of inducing QI leaf fan 8, 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, by the array waist hole 10 in check valve sheet 9, enters the 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.
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, as being processed into, can directly connect the tapered of corrugated tube, maybe can connect the irregular type with sealing ring 19 grooves of elbow bend etc.
Below the preferred embodiment of the invention is illustrated, but the invention 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 the invention spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
