Further, further include following steps in step S300：
S310, haemodialysis control unit start the imbibition from liquid storage container 400, and the supplying valve 510 opened on liquid supply pipe 500 starts
Feed flow；Meanwhile feed flow detection device 420 is monitored the liquid level in liquid storage container 400, when in liquid storage container 400
When liquid level reaches alarming levels, step S200 is recycled to continue mixed liquid；
When S320, haemodialysis control unit do not have always imbibition to be more than 15 minutes, automatically or closes entire feed flow by operating personnel and fill
It sets；Moreover, in the system of closing, emptying operation is carried out automatically first with evacuated tube 600：Feed water valve 120 is first closed, and is opened
Lower liquid valve is opened the first suction pumps 310 and is shut down when the second level detection mechanism 230 can't detect liquid after 2 minutes, and
The exhaust-valve 610 in evacuated tube 600 is opened while opening the first suction pumps 310, exhaust-valve 610 is closed in emptying after five minutes.
In technical solution provided by the invention, by mixer to chlorination sodium raw materials and purifying in liquid dispensing container 200
Water is sufficiently stirred, and more pure sodium chloride solution is obtained, and cooperation suction pumps make the sodium chloride solution configured mixed
It carries out with ionic liquid, purified water being hybridly prepared into A concentrates in real time in liquid pipe 300, and enters in liquid storage container 400 for blood
Dialysis machine uses.Whole process is performed fully automatic, and producing device is concentrated according to the sodium chloride solution of storage and the A being formulated
The capacity of liquid, the startup and closing of suction pumps in real-time control so that efficiency is increased to maximization.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
