The sterilization unit 12 (Fig. 5) represents two UV lamps 44 interconnected by the highway 43, each of which is placed in the case 45, and the walls of the lamp and the case form the chamber 46 for the flow of dialysis fluid. The chamber 5 is sealed by gaskets 47 located in both ends of the casing 45. The input 48 of the dialysing solution of the sterilization unit 12 is connected to the heating unit 11, and the output 49 of the dialysing solution is connected to the dialysis temperature control unit 13.

Each of the dispensers 16 and 16 filing and

 removing dialysis solution (Fig.6)

consists of two elastic tanks 50 and 51

5 with a limited maximum filling volume, the capacity 50, which dispenses the dialysis fluid, is above the patient's body, and the capacity 51, the removal dosage, is below the patient's body. The input line 52 through the valve mode switch 53 is connected to the inlet of the container 50. The output of which is connected through the valve mode switch 54 through the valve and the tee 55 is connected to the abdominal catheter 56. The retractable branch of the triplex 55 is connected through the valve 57 modes connected to the entrance of an elastic container 51, dispensing removal, the output of which by line 58 through a valve switch 53 mode 10mov connected with the sewer drain.

The device works as follows.

At the command of the low water sensor 17, water purification unit 2 is turned on, starts water withdrawal from the water purification unit 1, and supplies twice purified water to purified water reservoir 3. With the achievement of the upper water level by the signal of the sensor 18 of the upper level, the water re-purification unit 2 is switched off. With a drop in the water level, as it is consumed, and at a signal from the low level sensor 17, the unit 2 re-purifies the water 25 again and the cycle repeats. The salt concentrate from the tank 4 and the water from the tank 3 for purified water under the action of hydrostatic pressure flow through lines 21 and 22 of the water metering unit 5 and 30 salt concentrate into the corresponding elastic containers 19 and 20 of limited volume (filling mode). The signal from the sensor 31 for adjusting the volume of the dialyzing solution attached to 35 stationary bar 28 of the stimulation unit 8 for production of dialysis solution arising from pressing its button by the bracket 30 moving upwards by the action of the springs 29 as the elastic tank 40 empties 40, time delay relay valve 23 modes, which puts the unit 5 dosing of water and salt concentrate in the drain mode. Meanwhile, the flow of 45 fluids through line 21 and 22 is stopped. Water and salt concentrate in certain doses under the action of hydrostatic pressure first flow through lines 24 and 25, and then through 50 common lines through the first inlet 26 of stimulation unit 8 for the production of dialysis fluid to elastic capacity 27. A metering unit is switched on simultaneously with valve switching 23 7 glucose-55 goats, which is a roller asos, which with a given speed delivers glucose from tank 6 for glucose to the elactic capacity 27 of block 8 of regulation, production of dialyzing solution

through the second input 32, the Duration of the discharge mode of the unit 5 for the dosing of water and salt concentrate is set by the time delay relay. After the time allotted for a full drain, the valve switch 23 modes translates the unit 5 for dispensing water and salt concentrate to the filling mode, and the cycle repeats, and the glucose metering unit 7 is turned off.

As the elastic container 27 is filled, the bracket 30 moves away from the button of the sensor 31 for adjusting the volume of dialysis fluid. After the supply of concentrates and water is stopped, the roller pump 9 is blocked for the period of the discharge mode and, after output 33 of the dialysis stimulation production unit 8, the latter is fed to the input 41 of the elastic container 34 of the dialysis continuity unit 10. The signal for switching on the roller pump 9 supplies by means of the bracket 40 a sensor 39 of the lower level due to the action of the springs 35 driving the elastic capacitance 34 relative to the bracket 37 fixed to the fixed bar 36. With the upper filling level reaching the sensor 38, the roller pump 9 is turned off. The dialysis solution through the outlet 42 of the elastic vessel 34 under the action of the hydrostatic pressure enters the preheating unit 11, where the dialysing solution temperature is maintained. After the preheating unit 11, the preadiased solution enters the sterilization unit 12 through the inlet 48. Continue Bottom up in chamber 46, formed by housing 45, UFO lamp 44 and sealing gaskets 47, the dialysis solution is sterilized. Through a connecting line 43, the dialysing solution enters the second sterilizing section, where it is irradiated once more. The latter performs an emergency function in case of a failure of one of the lamps during the dialysis process. Through the exit 49, the dialysis solution from sterilization unit 12 enters the temperature control unit 13 of the dialysis fluid. Further, through the safety valve 15, which interrupts the flow of dialysate in case of violation of temperature and conductivity parameters, as well as in the event of an unexpected power cut, the dialysis solution is fed to one or more dispensers 16 and 16 for supplying and removing dialysis solution.

Dispenser 16 supply and removal of dialysis solution (Fig.6) works as follows. Ready-to-use dialysis fluid through line 52 through the valve mode switch 53 flows under the action of hydrostatic pressure into an elastic container 50, metering an infusion into the abdominal cavity. After filling the reservoir 50 to a predetermined maximum volume, the dialysing solution on line 54 through the valve mode switch 53, the tee 55 and the abdominal catheter 56 infuse into the abdominal cavity. The spent solution leaves the abdominal cavity through the same catheter 56 and tee 55 and through line 57 through the valve mode switch 53 flows into the elastic tank 51. After filling the tank 51 to the specified maximum volume, the spent solution flows through line 58 through the valve mode switch 53 into the sewer. The dispenser 16 for supplying and removing the dialyzing solution operates in two modes: the filling mode of both elastic vessels (tank 50 with fresh dialysis solution, and tank 51 with spent) and in drain mode (from tank 50 into the abdominal cavity, and from tank 50). 51 - to the sewer). Modes are switched by a single electromagnet, controlled by a timer, and a counteracting spring. They open the main lines 52 and 57, block highways 54 and 58 (filling mode), or vice versa, highways 52 and 57 are closed, and highways 54 and 58 are open (drain mode). Thus, a constant volume (2 l) is maintained in the abdominal cavity. The rate of change of the solution can reach 7-8 l / h or more.

The proposed device for peritoneal dialysis avoids any technical complications during the treatment procedure, worsens the patient's condition by separating glucose from the salt concentrate and enhances the sterility of the administered dialyzing solution. The device makes it possible to vary the osmolarity of the solution during peritoneal dialysis by changing the concentration of glucose, which are flexible in influencing the removal of water from the body. The device provides up to 4 simultaneous high-speed peritoneal dialysis at a solution change rate of 100 ml / min or more.
