Two of ultrafiltration control system groups of work package work process that structure is identical in the dialysis solution supply circuit:
First via work package: when feed liquor valve I 43 opens, during feed liquor valve II 44 closed conditions, prepared the fresh dialysis fluid of finishing, flow into fresh dialysis fluid container I 41 from mixer 28 bottom delivery outlets 39, liquid air detector 40 detects the intact back of dialysis fluid flow feed liquor valve I 43 and closes automatically, after flowing into dialysis solution in the fresh dialysis fluid container I 41 this moment and being weighed, dialysis solution switching valve 48 automatically switches to fresh dialysis fluid container I 41, under the effect of dialysis solution liquid feeding pump 47 and gravity sensor 45 dual controls, fresh dialysis solution is supplied with dialyser 6 by certain flow, dialysis solution and blood carry out the ion disperse in dialyser 6, ultrafiltration, toxin is displaced in the dialysis solution, under Pump for giving-out 49 and gravity sensor 53 dual controls, the ultrafiltrate that will contain the dialysis solution of toxin and deviate from the human body is extracted into waste fluid container I 50 through fluid switching valve 52 and carries out Weighing, the waste liquid weight that measures and the weight difference of fresh dialysis fluid and the ultrafiltration rate of setting compare, according to the flow of the Pump for giving-out of feedback control as a result 49 relatively, thereby finish the ultrafiltration of this group period.Next group of changing to be cut dumps the waste liquid among the waste fluid container I 50 during working procedure.
The second road work package: in the first via is finished dialysis solution inflow fresh dialysis fluid container I 41, feed liquor valve I 43 closes, feed liquor valve II 44 was open after dialysis solution was prepared once more and finished, dialysis solution is flow into fresh dialysis fluid container II 42 from delivery outlet 39, being detected the intact back of dialysis fluid flow feed liquor valve II 44 by liquid air detector 40 equally closes automatically, this moment, container II 42 interior dialysis solution were also weighed, treat that dialysis solution uses up in the fresh dialysis fluid container I 41, automatically switch to fresh dialysis fluid container II 42 by dialysis solution switching valve 48 again, finish the same program of first via work package, under Pump for giving-out 49 and gravity sensor 54 dual controls, the ultrafiltrate that will contain the dialysis solution of toxin and deviate from the human body is extracted into waste fluid container II 51 by fluid switching valve 52 and carries out Weighing, the waste liquid weight that measures and the weight difference of fresh dialysis fluid and the ultrafiltration rate of setting compare, according to the flow of the Pump for giving-out of feedback control as a result relatively, thereby finish Filtration Control.Meanwhile tapping valve I 55 opens, and the waste liquid among the waste fluid container I 50 is dumped by waste liquid pipeline 62 automatically.
Two groups of work packages that structure is identical, work alternately goes round and begins again, and realizes that dialysate flow and ultrafiltration are continuous.By weighing of gravity sensor, every group the fresh dialysis fluid and the weight difference of waste liquid are the ultrafiltration volume of this period.In time, the weight difference of fresh dialysis fluid accumulative total total amount and waste liquid accumulative total total amount is total ultrafiltration volume of overall process dialysis treatment at whole dialysis treatment.
Further specify the realization of ultrafiltration control system of the present utility model by following computing formula:
Shown in accompanying drawing, under the dialysis state, the original state of two groups of work packages is: fresh dialysis fluid container I 41 dress dialysis solution liquid are finished (W1=W), and waste fluid container I 50 waste liquids emptyings (W3=0); Fresh dialysis fluid container II 42 dialysis solution use up (W2=0), and waste fluid container II 51 has filled waste liquid (W4=W).Dialysis solution in the fresh dialysis fluid container I 41 after weighing by gravity sensor, carried out Weighing into and out of liquid pump among the waste fluid container I 50 through being extracted into behind the dialyser, the waste liquid amount in the waste fluid container I 50 is made of the weight (being ultrafiltration volume) of the excessive moisture of extracting out in container I 41 dialysis solution weight and the human body at this moment.The weight difference of container I 41 fresh dialysis fluids and container I 50 waste liquids is the ultrafiltration volume of this period.
Dialysis solution in container I 41 uses up, and automatically switches to the second road assembly that preparation is in advance finished: fresh dialysis fluid container II 42 dress dialysis solution liquid are finished (W2=W), and waste fluid container waste liquid II 51 emptyings (W4=0); Fresh dialysis fluid container I 41 dialysis solution use up (W1=0), and waste fluid container I 50 has filled waste liquid (W3=W).Finish same workflow.Therefore:

In time, the weight difference of fresh dialysis fluid accumulative total total amount and waste liquid accumulative total total amount is total ultrafiltration volume of overall process dialysis treatment at whole dialysis treatment.
Supply with the pressure of water route part in order to alleviate dialysis solution, four liquid container I 41, II 42, I 50, II 51 respectively have an emptying QI KOU 63,64,65,66, are convenient to alleviate fluid pressure, reach normal steadily ultrafiltration.
Temperature sensor (57) and conductivity monitor (58) are housed on the liquid feeding pump front end pipeline. when departing from when being provided with setting value appears in dialysis solution electric conductance or temperature, dialysis solution does not enter dialyser (6), automatically it is discarded to change by-passing by bypass valve (59), under bypass condition, dialysis solution is isolated by isolating valve (60) simultaneously, forbid that underproof dialysis solution enters dialyser once more, has effectively improved the treatment safety.
When the dialyser rupture of membranes occurring, lose blood outward in order to prevent the patient body, at the preceding blood leakage monitor (61) that designed of Pump for giving-out (49), detect Lou blood after machine in alarm, stop dialysis.
In dialysis procedure, blood circuit occurs that air (3) or tremulous pulse (4) or vein pressure (5) are unusual or depart from, and then machine flow plug (13) in alarm is closed, and stops dialysis, and dialysis solution does not enter dialyser (6), changes by-passing and dumps.Whole dialysis procedure dialysis solution supply and tapping valve switch operating replace and are continuous, go round and begin again, and by controlling into and out of the liquid pump and the dual mode realization ultrafiltration volume of weighing, finish dialysis, and the employing flow jointly controls with weighing, and reaches accurate ultrafiltration.
According to the treatment needs, can set parameters such as dialysis time, dialysate flow, ultrafiltration volume, temperature, conductivity, anticoagulant consumption, blood flow and individuation dialysis ultrafiltration, when dialysis made it, machine finished dialysis automatically.
