Description
Technical field
The present invention relates to a kind of device making the quick mix homogeneously of gas with various, can be used for medical breathing machine, to carry out sky oxygen fast
Speed uniformly mixes, and makes that oxygen concentration sensor is more rapid, truly reflect oxygen concentration, meets machine setting requirements, belongs to gas
Body control field.
Background technology
Existing medical breathing machine is realized empty oxygen and is quickly mixed so that oxygen concentration sensor is more rapid, truly reflect oxygen
Gas concentration, is met respirator setting requirements and is mainly realized by two ways：
1）Using empty oxygen mixer, oxygen and air are respectively connected to sky oxygen mixer, when respirator adjusts oxygen concentration, pass through
Empty oxygen mixer is controlled to oxygen concentration, makes outlet side oxygen concentration reach machine setting requirements, but empty oxygen mixer price
Costliness, the empty oxygen mixer price of least significant end also will tens of thousands of units.By this device, respirator is adjusted during oxygen concentration it is only necessary to lead to
Overregulate proportioning valve and the air mass flow needed for this concentration and oxygen flow are accessed this device, quick, uniform by this device
Mixing, outlet side oxygen concentration sensor records numerical value and is actual concentration numerical value, i.e. machine setting numerical value, low side proportioning valve
Meet use requirement, cheap.
2）Do not use empty oxygen mixer, however it is necessary that setting up high-end Platform of hardware, using the mode fed back not
Adjust air and oxygen flow with stopping so that oxygen concentration reaches setting requirements.When respirator adjusts oxygen concentration, required air
Flow and oxygen flow reach at oxygen concentration sensor, because gas is not also sufficiently mixed, the number that oxygen concentration sensor records
It is worth for instant numerical value, this numerical value and setting numerical value have deviation, and this deviation feeds back to Platform of hardware, by platform ceaselessly
Adjust proportioning valve and change air mass flow and oxygen flow, so that sensor values move closer to setting numerical value, the method responds
Time is slow, controls difficulty high, adjusts Platform Requirements high.

Specific embodiment
Below in conjunction with the accompanying drawings medical gases mixing arrangement of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, medical gases mixing arrangement of the present invention is fixed on inside medical breathing machine, is placed in respirator and enters
Pneumatic module rear end, centre can be provided with pressure maintaining valve, flow-regulating proportional valve and flow transducer.
Two air inlets 3 that respirator air intake assembly oxygen out and air pass through on air inlet module 1 respectively enter successively
Enter and in the one-level hybrid chamber 2 in air inlet module 1, carry out primary mixing, for further gas mixing evenly, air inlet 3 with
Cushion chamber 4 is added, now gas not yet mix homogeneously between one-level hybrid chamber 2.
Primary mixed gas enters buffer module 5 by the air flue 7 in buffer module 5 central authorities, the two of buffer module 5
Carry out secondary mixing in level hybrid chamber 6.
There is inducing QI leaf fan 8, mixed gas are done same in the presence of inducing QI leaf fan 8 after entering buffer module 5 in buffer module 5
To rotational flow, effectively increase the gas mixing time, make mixing evenly, fully, gas elementary mixing now is equal
Even.
Uniformly mixed gas backs down valve body diaphragm 12, enters, by the array waist hole 10 in check valve sheet 9, mould of giving vent to anger
Block 14, because valve body diaphragm 12 adopts thin rubber to make, so only need the impulse force of very little can back down valve body diaphragm 12.
Array waist hole 10 in check valve sheet 9 is the little irregular waist hole of outer imperial palace of circular array, is ensureing use requirement
In the case of maximize and give vent to anger hole area.
Check valve sheet 9 is the indent conical surface with the binding face of valve body diaphragm 12, increases mixed gas and valve body diaphragm 12
Contact area, makes gas be easier to back down valve body diaphragm 12 and enters module 14 of giving vent to anger, also further increase gas outlet 16 face
Long-pending.
There is heavy platform 11 at the cylindrical place of the check valve sheet 9 indent conical surface, and valve body diaphragm 12 sinks in check valve sheet 9 completely, mould of giving vent to anger
Gas in outlet chamber 15 in block 14 is less susceptible to enter the gap between valve body diaphragm 12 and check valve sheet 9, more efficient ground resistance
Stop mixed gas backflow.
Module of giving vent to anger 14 is provided with concentration sensor interface 17 and other various expansion interfaces 18, and module 14 of giving vent to anger
Outlet side can be processed into different forms to meet different use requirements, be such as processed into and can directly connect the tapered of corrugated tube, or
Irregular type with sealing ring 19 groove of elbow bend etc. can be connect.
Below the preferred embodiment to the invention is illustrated, but the invention be not limited to described
Embodiment, those of ordinary skill in the art also can make without prejudice on the premise of the invention spirit a variety of equivalent
Modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
