Abstract

The invention relates to medical technology. The purpose of the invention is to reduce blood loss. The device consists of a utero-vaginal probe with a detachable joint 2 at the handle and a curved working end. The probe surface is provided with perforated 19/3 holes and ribbing 5. The intermediate part 6 of the probe is equipped with a movable elastic sealing plate 7 and a discharge pipe 8 connected by tubes 9 with a graduated reservoir receiver 10, a three-way valve 11, an automatic evacuation regulator 12 and a vacuum apparatus 13. The one-piece inner sheath 14 has a removable connection 15 with a handle. Inside the tube 16 passes the sensor 17 of the temperature of the electrothermometer 18. The inlet pipe 19 is connected to the coolant supply tube 20, which through the outlet tube 22 enters the receiver 23, and then to the pump 24, which supplies refrigerant to the probe until the temperature sensor registers given amount of hypothermia. 2 Il. & (About IE 4 CO sg

The invention relates to medical technology and can be used in obstetric gynecological and surgical practice.

The purpose of the invention is to reduce blood flow by reducing the morbidity of the effect of low pressure and creating additional cooling.

In FIG. Figures 1 and 2 show the device for postpartum hemorrhage stopping.

N crpoiicTBo consists of a uterine-vaginal probe 1 with a detachable connection 2 at the handle 3 and a working end 4 bent to uterine curvature 4. The surface of the uterine-vaginal probe is supplied

on perforated holes and ribbing 5. Integral vaginal-interfacial probe 6 is equipped with an elastic shim sealing plate 7 and a branch pipe 8 connected by tubes 9 with a volume-graduated reservoir 10, a three-way valve 1, and an automatic volume graduated by volume. vacuum vacuum device 12 and vacuum apparatus 13. Inside, under the perforated ribbed shell, the probe is equipped with a rigid solid shell 14, the distance between them is 0.5-0.7 cm. The integral inner shell has a removable connection 15 with a handle .

But the center line of the probe passes through the tube 16, hermetically connected to the handle and the top of the inner shell and freely passing through the outer perforated ribbed shell. Inside this tube, hermetically connected, passes the sensor 17 of the temperature of the electrothermometer 18, which directly reaches the tissues of the uterus and registers its temperature.

In the cavity of the inner shell, the inlet pipe 19, connected to the coolant supply pipe 20, is somewhat longer than the outlet pipe 21. The inlet pipe is open at the top of the integral shell and the coolant flowing out of it, evenly flowing around the inner walls of the integral shell, enters through the tube 22 of the handle to the receiver 23. From the receiver, the refrigerant enters the pump 24, which delivers the refrigerant again to the uterine-moisture probe until the temperature sensor registers the specified amount of hypothermia. As the temperature of the refrigerant in the receiver rises to the level of the environment, the controller 25 automatically turns on the source 26 of the refrigerant and maintains the level of hypothermia.

The device works as follows.

After dilution of the sexual intercourse with the second hand, take the uterine-vaginal tubular probe 1 by the handle and insert it into the vagina. Then, using the free hand, fix the bottom of the uterus through the brush wall and advance the probe from the vagina into the uterus. After this

The movable sealing plate 7 is moved along the whole vaginal-interstitial part of the probe 6 to the external genitals and tightly pressed, providing these most reliable sealing of the vaginal space. After switching on the vacuum cooler 13, the automatic vacuum regulator 12 g 0 allows one to maintain a predetermined mode of negative pressure in the uterine vaginal space. After a negative pressure occurs in the uterine-vaginal space, blood accumulated in the uterine cavity and vagina is sucked out through the perforation holes in the probe and through the discharge tubes 9 through the connecting tubes 9 into the uterine cavity 10. After reaching the specified negative pressure to the uterine-vaginal tubular probe, or rather to its perforated ribbed surface 5, the walls of the uterus and vagina are sucked. Blood vessels are pinched against the ribbed edges of the outer surface of the probe and the bleeding stops. By volumetric calibration of the reservoir receiver, you can accurately determine the volume of blood loss and immediately restore it. A three-way valve 11 is discharged if necessary.

After stopping the bleeding, the source 26 of the refrigerant is supplied, which through thermally insulated flexible connecting tubes and inlet pipe 19 enters into the whole internal shell, evenly flows around it and takes heat on itself, through outlet pipe 22 through outlet pipe 21. reservoir receiver refrigerant enters the pump 24, which re-supplies it to the uterine-vaginal probe. The sensor 17 on the electrothermometer 18 shows the temperature of the cooled tissue. If the temperature reaches a predetermined value, the pump 24 is automatically shut off and the refrigerant does not move around the probe, the temperature exchange drops sharply. If the tissue temperature rises again, the pump automatically turns on and the preset hypothermia mode is easily reached again. If the temperature of the refrigerant in the receiver rises, the automatic controller 25 will turn on the refrigerant source 26 and the required hypothermia mode will be maintained.
