In general, hemodialysis, peritoneal dialysis, and kidney transplantation are methods that can sustain life for patients with chronic renal failure who have lost kidney function due to various diseases.

In the kidney transplant method, the family, relatives, and kidneys can receive kidneys from healthy brain lions, but kidney transplantation can be performed only if various examinations determine that the provider is completely healthy and that one kidney can be healthy after surgery. In addition, since there are extremely limited providers of kidneys, most patients with chronic renal failure rely on hemodialysis and peritoneal dialysis.

On the other hand, hemodialysis and peritoneal dialysis methods are neotherapy for patients with chronic renal failure, and the blood accumulated in waste patients and dialysis fluids similar in composition to the extracellular fluid of normal humans flow in opposite directions, such as elements accumulated in blood. The principle is to remove the wastes by the principle of diffusion by the difference in concentration and to make the difference of hydrostatic pressure and to filter the plasma to remove the excess water in the body.

Among them, the hemodialysis method should be dialyzed using a dialysis machine after the patient has visited the hospital. Usually, the treatment time is four hours once, three times a week for about 12 hours a week to completely cleanse the patient's blood.

However, the dialysis solution used in the hemodialysis and peritoneal dialysis method is prepared by inserting the powder into the dialysis solution manufacturing tank by a pharmaceutical company, rotating the impeller, and then delivering the dialysis solution into the dialysis solution container, thereby increasing the cost according to the dialysis solution container or logistics cost. There is a problem that the value of the dialysate provided to the patient increases.

In addition, the hospital side has a problem to secure a separate space for storing the dialysate delivered from the pharmaceutical company.

Therefore, the object of the present invention was devised to solve the problems as described above, after preparing the dialysis solution by mixing the reverse osmosis pressure purified water to acid salt powder and carbonate powder, and automatically supplying the prepared dialysis solution to supply the dialysis solution automatically To provide a device.

Accordingly, the official receives the amount of dialysis solution (bicarbonate) produced (S341).

Then, after a certain amount of bicarbonate liquid production amount (for example, 200 L) is received and confirmed by the person concerned, and when a mix signal is received through the BMT screen 250b shown in FIG. 6, the control terminal 200 opens the B1 and B2 valves. By opening, RO water corresponding to 200 L of bicarbonate produced in the BMT 130 is introduced from the RO water storage tank 110 through the B1 valve ⇒ BP2 pump and the B1 valve ⇒ BP2 pump ⇒ B2 valve (S343).

Subsequently, the control terminal 200 drives the BP1 pump driven in the reverse direction and opens the B2 valve, so that the RO water and the bicarbonate powder in the BMT 130 are rotated for a predetermined time in the reverse order of the B2 valve ⇒ BP1 pump ⇒ BMT 130. After mixing, the BP2 pump is driven and the B3 valve is opened to mix the bicarbonate powder and the RO water in the BMT 130 for a predetermined time in a forward order of the BP2 pump ⇒ B3 valve ⇒ BMT 130 (S345).

The bicarbonate solution stored in the BMT 130 is stored in the BRT 160 through the BP2 pump ⇒ B5 valve ⇒ BP4 pump (S347).

At this time, when the dialysate of the BRT 160 is below a certain amount (eg, 100 L), the dialysate is automatically from the BMT 130 to the BRT 160 until the dialysate of the BRT 160 is a certain amount (eg, 200 L). When the bicarbonate liquid stored in the BMT 130 is 0 L, the supply of the bicarbonate liquid is automatically stopped.

Subsequently, when the control terminal 200 receives a dialysate supply signal through a hemodialysis device (not shown) installed in the dialysis room (not shown) from the person concerned, the control terminal 200 drives the BP4 pump and opens the B6 valve, thereby providing the amount required by the relevant person. The bicarbonate solution is supplied (S349).
