Further, in step s 200, also comprise the steps:
S210, the second level detection mechanism 230 of startup liquid level detection device, detect the liquid level of current liquid dispensing container 200
Whether less than the minimum scale preset, when the liquid level of described liquid dispensing container 200 is not less than described minimum scale, get feed flow inspection
Survey the feed flow signal that device 420 sends, start described first suction pumps the 310, second suction pumps 320 and the 3rd suction pumps 330；
I.e. receive feed flow signal, and the second level detection mechanism 230 detects in the second liquid distribution cavity 202 have liquid
After, start the first suction pumps 310 and the sodium chloride solution in second liquid distribution cavity 202 is pumped in mixed liquid pipe 300, start simultaneously
Other ionic liquid is pumped in mixed liquid pipe 300 by two suction pumps 320, makes sodium chloride solution first mix with ionic liquid, restarts the
Purified water is transported in mixed liquid pipe 300 by three suction pumps 330 by feed tube 100, with sodium chloride solution, ionic liquid by a definite proportion
Enter in liquid storage container 400 after example mix homogeneously；
S220, detect that the liquid level of described liquid dispensing container 200 is less than described minimum quarter when the second level detection mechanism 230
Degree, controls described first suction pumps the 310, second suction pumps 320 and the 3rd suction pumps 330 is shut down.I.e. second level detection mechanism
230 detect in the second liquid distribution cavity 202 after no liquid, and first suction pumps the 310, second suction pumps the 320, the 3rd suction pumps 330 stops
Machine；And return to step S100, proceed dosing.
S300, described liquid storage container 400 are connected with haemodialysis control unit by feed pipe 500, and carry described A concentrated solution extremely
In described haemodialysis control unit.
Further, in step S300, also comprise the steps:
S310, haemodialysis control unit start imbibition from liquid storage container 400, and the supplying valve 510 opened on feed pipe 500 starts
Feed flow；Meanwhile, the liquid level in liquid storage container 400 is monitored, when in liquid storage container 400 by feed flow detection device 420
When liquid level reaches alarming levels, it is recycled to step S200 to proceed mixed liquid；
When S320, haemodialysis control unit did not had imbibition more than 15 minutes always, automatically or by operator close whole feed flow dress
Put；And, when closing closed system, automatically carry out emptying operation first with evacuated tube 600: the most first close feed water valve 120, and open
Lower liquid valve, after 2 minutes, opens the first suction pumps 310 until shutting down when the second level detection mechanism 230 can't detect liquid, and
Open the exhaust-valve 610 in evacuated tube 600 while opening the first suction pumps 310, after emptying 5 minutes, close exhaust-valve 610.
The present invention provide technical scheme in, by mixer in liquid dispensing container 200 to sodium chloride raw material and purification
Water is sufficiently stirred for, it is thus achieved that the purest sodium chloride solution, coordinates the sodium chloride solution that suction pumps makes to have configured mixed
Liquid pipe 300 carries out being hybridly prepared into ionic liquid, purified water A concentrated solution in real time, and enters in liquid storage container 400 for blood
Dialysis machine uses.Whole process is performed fully automatic, and producing device concentrates according to sodium chloride solution and the formulated A of storage
The capacity of liquid, the startup of suction pumps and closedown in controlling in real time so that efficiency brings up to maximize.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Can not therefore be construed as limiting the scope of the patent.It should be pointed out that, come for those of ordinary skill in the art
Saying, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
