Device, buffer container 3, soft deformable plastic container 4, wet tank to be aging 5, gas source 7.
Soft deformable plastic container 4 is finished product blood bag, including bag body and and communicating pipe for being arranged in bag body, communicating pipe
One end be connected with bag body inner cavity, the other end extends on the outside of bag body, and communicating pipe is arranged to extending on the outside of bag body on one end
There is the pipe clamp (not shown in figure 1) of opening or closed communication pipe.Bag body includes the forward and backward plastic foil being oppositely arranged, forward and backward plastics
The surrounding sealing of film is into a single integrated structure.
Communicating pipe is connected with the first valve port of triple valve 6, and the second valve port of triple valve 6 is stored up by pipeline and liquid to be aging
Tank 5 is connected, and the third valve port of triple valve 6 is connected by pipeline with vacuum pump 1.
The outlet being connected on wet tank 5 to be aging with the second valve port is the liquid outlet for liquid to be aging discharge, to old
Change and is additionally provided with the extruding gas access being connected with gas source 7 on wet tank 5.Gas source 7 is High Purity Nitrogen airbag.
Vacuum meter 8, drying device and buffer container 3 are provided in the connecting pipeline of vacuum pump 1 and third valve.Dry dress
It is set to the drying tower 2 being sequentially connected.Buffer container 3 is surge flask.
Pipeline between vacuum pump 1 and the communicating pipe of bag body forms vacuum-pumping pipeline, wet tank 5 to be aging and bag body
Pipeline between communicating pipe forms fluid injection pipeline.
The course of work of apparatus above is as follows: the first valve port of adjustment triple valve 6 first is connected to third valve port, is vacuumized
Pipeline connection (the first valve port, the second valve port interface channel accordingly close), open vacuum pump 1 finished product blood bag is vacuumized；It takes out
After vacuum, the front and back plastic foil of finished product blood bag, which is bonded to each other, is completely exhausted out the gas in bag, then adjusts the first of triple valve 6
Valve port is connected to the second valve port, fluid injection pipeline connection (the first valve port, third valve port interface channel accordingly close), by gas source 7
It is passed through extruding gas into wet tank 5 to be aging, squeezes gas for the liquid to be aging in wet tank 5 to be aging by going out liquid
Mouth discharge, then enter in finished product blood bag (height of adjustable liquid outlet is higher than inlet to facilitate liquid to be discharged) through inlet,
After the completion of liquid conveying to be aging, the communicating pipe in finished product blood bag is clamped with pipe clamp, liquid to be aging can be made in anaerobic item
It is saved under part.
Valve can be set at the liquid outlet of wet tank 5 to be aging, before conveying liquid to be aging, valve is closed,
The air in the connecting pipeline of the second valve port and inlet is shifted to vacuum-pumping pipeline under the action of negative pressure at this time, then by adjusting
Triple valve and vacuum extract the air in fluid injection pipeline out.
The occasion using liquid to be aging is being needed, the pipe clamp on the communicating pipe of finished product blood bag is being unclamped, is being measured as needed
The liquid to be aging in it is squeezed out, the actual volume in finished product blood bag accordingly compresses, it then proceedes to be clamped communicating pipe with pipe clamp,
Can continue that the liquid to be aging in finished product blood bag is kept to be in anaerobic state.
The embodiment of senile experiment method of the invention, using the device for being used to prepare aging sample above, including it is following
Step:
1) it vacuumizes deoxygenation: finished product blood bag is vacuumized, forward and backward plastic foil mutually pastes finished product blood bag under the action of negative pressure
Tightly, the air in its inner cavity is discharged.
2) fluid injection: chemical flooding agent to be measured indentation is vacuumized in the finished product blood bag after deoxygenation and (is pressed into 350ml chemistry to be measured altogether
Drive agent), the communicating pipe in finished product blood bag is clamped with pipe clamp.
3) it tests: the finished product blood bag being sealed is subjected to senile experiment at 80 DEG C.After senile experiment 1d, by finished product blood bag
On pipe clamp unclamp, squeeze out 15ml chemical flooding agent to be measured, detect and record its apparent viscosity.Senile experiment 5d, 10d, 20d,
After 30d, 40d, 45d, chemical flooding agent to be measured is squeezed out by same operation, detects and records its apparent viscosity.
During the above senile experiment, part liquid may be remained in the outside pipeline section of pipe clamp clamped position on communicating pipe
Body, the partially liq are contacted with air, can squeeze out in time the partially liq, to avoid may be to follow-up test bring not
It is good influence (can also next time test before, using the partially liq as waste liquid discharge, with the liquid of extrusion intracavitary out of bag body into
Row test).
Comparative example
The chemical flooding agent thermal stability experimental method of comparative example conveys the device and the basic phase of embodiment of liquid to be aging
Together, difference is only that, replaces finished product blood bag using ampoule bottle, is the practical new of CN204841532U with specific reference to Authorization Notice No.
The related content of type patent disclosure；After ampoule bottle heat sealing, senile experiment is carried out at identical conditions.
The experimental result of the thermal stability experimental method of embodiment and comparative example is investigated, it is specific as shown in table 1.
The Comparative result of 1 differing thermal stabilities experimental method of table
As shown in Table 1, the ampoule bottle method of the experimental result of the method for embodiment and comparative example is almost the same,
To drive the thermal stability of agent for evaluating chemical.But the method for embodiment realizes the continuous use of liquid to be aging, which save
The anaerobic transmission process repeatedly of liquid to be aging, has saved the dosage of ampoule bottle, has reduced experimental cost.
The above experimental method is suitable for temperature in 80 DEG C of sample aging experiments below.Temperature is too high, in senile experiment mistake
Cheng Zhongshui (solvent) will become gaseous state, and blood bag is caused to expand as balloon, and volume increases, so that aged samples do not have representative
Property.
