3 both ends of conduit extend respectively to 2 bottom of the first cavity 1 and the second cavity；Inlet 31 is provided on first conduit 3；Institute
It states inlet 31 to be connected to by three-way valve 32 with the first conduit 3, three-way valve 32 is equipped with first switch 321 and second switch
322, first switch 321 controls the on-off of inlet 31, and second switch 322 controls the first conduit 3 close to 1 side of the first cavity
On-off；The second conduit 11 is provided with and communicated on first cavity 1；The one end of second conduit 11 far from the first cavity 1 with
External world's connection；Third conduit 21 is provided with and communicated on second cavity 2；The third conduit 21 far from the second cavity 2 one
End is connected to setting with operating room gas source interface；Gas outlet 22 is provided on the third conduit 21；The gas outlet 22 passes through two
Port valve door 23 is connected to third conduit 21, and two-way valve 23 is equipped with third switch 231, and the control of third switch 231 is close to operation
The on-off of the third conduit 21 of room gas source interface side.
It further include protecting crust 4；First cavity 1 and the second cavity 2 are mounted in protecting crust 4, when needing to make in operation
It when standby mixed gas only needs that operating room gas source interface is connect and can be brought into operation with third conduit 21, while protecting crust 4
On can choose to install the components such as carrying handle and facilitate carrying；The position of corresponding second cavity 2 in 4 side of protecting crust is equipped with observation window 41,；Institute
Stating the second cavity 2 is transparent plastic container, and side is labeled with containing mark, is first filled during the preparation process into the second cavity 2
Thimerosal (such as 75% alcoholic solution), when close to the output of operating room gas source carbon dioxide or oxygen through third conduit 21 enter the
When two cavitys 2, the volume of inputted gas can be learnt by the discharged volume of thimerosal.
It is provided with sealing rod 111 in second conduit 11, if gas preparation facilities has thimerosal in the first cavity 1
Unexpected overturning, sealing rod 111, which encounters to expand rapidly after the thimerosal of outflow, blocks the second conduit 11, avoids further letting out
Leakage.
The third conduit 21 is connected to setting with operating room gas source interface by adapter 42, is arranged on the adapter 42
There is flow switch 421, can prevent the gas moment in gas source from pouring in by 421 fine adjustment of flow switch, it is difficult to reduce operation
Degree.
Below for preparing 70% carbon dioxide of 100ml, the mixed gas of 30% oxygen, the second cavity 2 is selected
The plastic bottle of the transparent material of 100ml, preparation physiological mixed gas specific steps are as follows:
Step 1, first switch 321, second switch 322 and third switch 231 is fully open, with adapter 42 by third
Conduit 21 is connected with operating room carbon dioxide gas source interface, and opening flow switch 421 is filled with carbon dioxide gas into device will
Original air all empties in device, is then turned off first switch 321, second switch 322 and third switch 231, closes flow
Switch 421；
Step 2, first switch 321 and third switch 231 are opened, 100ml is injected into the second cavity 2 by inlet 31
Thimerosal, be then turned off first switch 321 and third switch 231；
Step 3, second switch 322 and flow switch 421 are opened, is filled with by third conduit 21 into the second cavity 2
70ml carbon dioxide, discharged thimerosal is entered in the first cavity 1 by the first conduit 3 at this time, is then turned off second switch 322
With flow switch 421；Here the thimerosal being discharged into the first cavity 1 also plays the effect of isolation outside air；
Step 4, carbon dioxide air source is switched into oxygen source, opens second switch 322 and flow switch 421, passes through
Third conduit 21 is filled with 30ml oxygen into the second cavity 2, and discharged thimerosal enters the first cavity by the first conduit 3 at this time
In 1, be then turned off second switch 322 and flow switch 421, as prepared in the second cavity 2 70% carbon dioxide finished,
30% oxygen mixed gas.
Step 5, second switch 322 and third switch 231 are opened, is used using mixed gas is extracted out from gas outlet 22,
Thimerosal in first cavity 1, which is flowed back into the second cavity 2 under differential pressure action by the first conduit 3, fills up the mixing being pumped
Volume shared by gas.
In addition, as shown in Fig. 2, first cavity 1 and the second cavity 2 are arranged in the form of mounted on top, set
Meter principle is: the placement if the first cavity 1 and the second cavity 2 are parallel to each other, in the step of extracting mixed gas, when first
When thimerosal is back to liquid level and flushes with the second cavity 2 in cavity 1, continues extraction process and just need to overcome in two cavitys between liquid
Pressure difference, mixed gas can not disposably be fully used；If the first cavity 1 and the second cavity 2 use the form of mounted on top,
First cavity 1 is placed in 2 top of the second cavity, then when extracting mixed gas, the reflux of thimerosal is in siphon in the first cavity 1
Can more thoroughly under the action of principle, the form that can be further improved the utilization efficiency of mixed gas, while stacking can be with
It is reduced significantly occupied space of the device on operating table, further increases its portability.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
