Description

The invention relates to medical technology, mainly to devices for artificial feeding of patients, for example, with surgical pathology of the stomach.

The purpose of the invention is to improve the absorption of the input nutrients by oxygenating the nutrient mixture.

FIG. 1 is a block diagram. Devices for probe feeding} in Fig. 2 - the design of the oxygenator. The device contains a tank 1 for the feed mixture, a stirrer 2, a tube 3 for collecting the feed mixture, a heater 4 with a temperature setting device 5, a pump 6 with a drive 7, an oxygenator 8 with inlets 9 and 10, and an outlet fitting 11, valves 12 and 13 s corresponding drives 14 and 15, an oxygen source 16 with a reducer 17 and a pressure gauge 18, fitting 19, probe 20, tubes 21-23, control block 24, made in the form of switching unit 25 and program block 26,

The oxygenator 8 contains the chamber 27, the elastic membrane 28, the glass 29. The side walls of the glass 29 contain

holes, for example, may be to increase the surface on which

Not us in the form of a metal grid.

Switching unit 25 is designed to switch the supply voltage to drives 7, 14 and 15, respectively, pump 6 and valves 12 and 13. Program block 26 provides control of the cych signals to the switching elements of switching unit 25 in accordance with the device operation algorithm.

The device works as follows.

Unscrewing the container 1 from the lid with the stirrer 2 and tube 3 for feeding the nutrient mixture fixed in it, fill it with the nutrient mixture and connect it to the pump 6. Check the presence of oxygen in the oxygen source 16 by means of a reducer 17 and a pressure gauge 18, and then connect it

with valve 12. The device is turned on. The tightness of the device is checked as follows. On the tube 23 impose a clip. If there is no leakage of the mixture through the joints of the elements of the device with tubes 21-23, namely tubes 3 for collecting the nutrient mixture from tank 1 and pump 6, pump 6 with oxygenator 8, oxygenator 8 with probe 20. then the mouth

The design is ready to go. The gear 17 sets the pressure of oxygen in the range of 3-4 atm, the value of the latter is controlled by the pressure gauge 18, the Program block 26 through the switching unit 25 and the temperature setpoint 5 set the temperature mode. With the help of heater 4, the nutrient mixture is heated in the tank 1 and then the temperature is kept within 38-. The homogeneity of the mixture is achieved by means of a stirrer 2, the operation of which is controlled by the control unit 24. By means of the program block 26, the necessary feeding and oxygenation mode of the nutrient mixture is selected.

From the tank 1 through the tube 3 for the intake of the nutrient mixture through the tubes 21 and 22 using a pump 6 is fed through the inlet fitting 9 into the oxygenator 8 portion of the nutrient mixture. The operation of the pump 6 is also controlled by the control unit 24 through the actuator 7. Once in the chamber of the oxygenator 8, the nutrient mixture spreads through the chamber 27 and the glass 29 installed in its center. The lateral surfaces of the latter, made in the form of a grid, allow

the mixture is in contact with oxygen, - In turn, oxygen enters the chamber 27 of the oxygenator 8 from the oxygen source 16 through the nozzle 10, and the valve 12 is open. At this time, there is a mixing of the nutrient mixture with oxygen by the type of microexplosion. The overpressure stretches the elastic membrane 28 of the oxygenator 8. After finishing the supply of hydrogen, the membrane 28 returns to its original position and pushes the oxygenated nutrient mixture through the outlet fitting 11 into the tube 23, and then through the fitting 19 into the probe 20, and the valve 13 is open. There is no return current of the feed mixture, since the discharge valve of the pump 6 is closed at this moment. Then a new portion of the nutrient mixture is sucked into the pump 6. At this point, the solenoid valves 12 and 13 are closed. I

The proposed device allows oxygenation of every portion of the nutrient mixture or every second, fourth, sixth, eighth or tenth, depending on the selected program in the program block 26.

The nutritional mixture is supplied in an oxygenator chamber 8 with a volume of 5 ml, and oxygen is supplied in a dose of 30 ml. Such a ratio allows achieving good oxygenation of the injected mixture.

The proposed probe feeding device provides batch oxygenation and supply of an oxygen-rich nutrient mixture, which results in an increase in the effectiveness of therapy for liver failure, and also improves the absorption of the nutrient administered during enteral tube feeding.

Due to the fact that the physiological method is used, it is possible with less risk to provide effective assistance to patients suffering from a serious condition.
