Value is equal.The partial air solved during bag body expansion between bag and framework cannot be from the upper end of framework to outflow
Go out and be mothballed between bag and framework, so as to cause bag can not be expanded into volume and framework internal volume it is equal in magnitude and
The problem for producing the solution concentration prepared in bag higher.
4th, the present invention is before three feed flows bag is connected with the entrance in the displacement liquid loop, and elder generation is toward filling reverse osmosis in bag
Water and make three kinds of solution of respective concentration, three kinds of solution in loop is replaced mixing and be configured to dialyzate and be supplied to
Analysis liquid supply switching circuit.Because the solution ratio of feed flow bag is simple, convenient and accurate, can rapidly match out and largely conform to
Ask the feed flow bag of concentration to replace the feed flow bag having been used up at any time, considerably reduce the time for changing bag, improve the efficiency of work.
5th, after the solution of three feed flow bags is configured to dialyzate in displacement liquid loop, dialyzate is carried out wherein the present invention
Supply loop and it is stored in displacement liquid reservoir bag all the way.After the solution of feed flow bag is finished, the new confession that will quickly can have been matched
Answer bag to install to carry out continuation supply, situation about interrupting, the effect that raising has been treated occurs in the supply that can prevent solution.
After the dialyzate in the displacement liquid reservoir bag of the road supply loop is finished, control device controls the work shape of corresponding magnetic valve
State makes displacement liquid loop be connected with another road supply loop and dialyzate is flowed into the displacement liquid reservoir bag of another road supply loop,
Whole process changes liquid without shutting down, it is ensured that energy dialyzate without interruption so that fluid flow and pressure stability, working stability can
Lean on, the blood pressure stabilization of patient during treatment dramatically reduces headache, Nausea and vomiting, extremely effective improves the effect for the treatment of.

The situation of size, and then ensure that the concentration of the proportioning solution of bag 1 meets required requirement.The big rootlet of volume inside framework 5
Determination is designed according to the volume design of bag 1 and the concentration of solution.If the volume of bag 1 exceedes the big of setting
It is small, then the concentration of the solution for making can be caused to cross less than desired value, and work as the size of the volume less than setting of bag 1, then
Can cause that the concentration of the solution for making exceedes desired value.
As shown in Fig. 2 in order to prevent during bag 1 expands the partial air between bag 1 and framework 5 cannot be from
The upper end of framework 5 flows outwardly and is mothballed between bag 1 and framework 5, so as to cause bag 1 to be expanded into volume and frame
The internal volume of body 5 is equal in magnitude and produce the higher situation of solution concentration prepared in bag 1.Opened on the inwall of the framework 5
Fluted 51, when reverse osmosis water is entered in bag 1 by liquid pipe 2, the outer surface of the bag 1 connects with the inner surface of framework 5
Touch and by the air extrusion between bag 1 and framework 5 to the groove 51.Bag 1 and framework during bag 1 expands
Partial air between 5 is extruded in groove 51 and is stored so that the outer surface of bag 1 can connect with the inwall of framework 5
Touch, so as to ensure that the volume size of bag 1 is equal with the desired value of setting.
The present embodiment also provides a kind of displacement liquid compounding system of application feed flow bag, as shown in Figure 1 and Figure 4, including it is described
Feed flow bag 6, and blood circuit 7, blood filter 8, displacement liquid loop 9, dialyzate supply switching circuit and waste liquid discharge loop
11, the feed flow bag 6 is connected with the entrance in the displacement liquid loop 9;The first entrance of the blood filter 8 passes through blood circuit 7
