Description

The utility model relates to medicine, namely to obstetrics and gynecology, and can be used to stop hypotonic or atonic uterine bleeding that has arisen.

Known two-balloon controlled balloon tamponade (catheter obstetric uterine balloon catheter Zhukovsky) (https://tamponada.ru), installed in the birth canal, creates the necessary pressure on the bleeding lower part of the uterus and on the vessels supplying blood to this area, eliminating the need for the implementation of a dangerous and complex surgical intervention. Zhukovsky's double-balloon tamponade catheter provides the ability to gently apply pressure to the lower uterus and the corresponding blood vessels.

The known product has only a mechanical effect, stopping bleeding by creating pressure on the lower part of the uterus and the corresponding blood vessels.

The closest in technical essence to the claimed technical solution is a device for stopping uterine bleeding (see patent No. 68883, class IPC А61В 17/42, z. 01.10.2007, op. 10.12.2007 Bull. 34), containing an intrauterine balloon catheter made of thin elastic rubber, with a length not less than the total length of the uterine cavity and the length of the vagina, a tubular elastic element rounded at the distal end with a length comparable, but not less than the total length of the uterine cavity and the length of the vagina, placed on the outer surface of the balloon irrigation and drainage tubes made of soft elastic form-containing material, the length of which is slightly longer than the length of the tubular element for delivery and support of the balloon catheter with the possibility of going beyond the birth canal outside - from the vagina. The distal ends of the tubes are rounded and have holes on their surface for the outlet and collection of the contents. On the side of the proximal end of the tubes, locking (switching) elements are installed on each of them, one of the tubes is configured to be connected to a syringe for introducing a hemostatic agent into the uterine cavity, the other tubes are connected to a container for collecting the outflowing fluid. The tubular element for delivery and support of the balloon catheter is connected to the reservoir for filling the balloon catheter with sterile liquid, the second tube, placed in the reservoir above the liquid level, is connected to the pressure gauge and at its end there is a pump for pressurization, while increasing the accuracy and efficiency of personnel exposure due to the presence of a pumping device in the form of a pump and a pressure control device - a pressure gauge with the compactness of the equipment, as well as other structural elements.

The disadvantage of the device is the unreliable and uneven distribution of the drug over the entire inner surface of the uterus.

The objective of the claimed utility model is the development of a device that ensures reliable stopping of uterine bleeding by uniform drug delivery with the possibility of distributing it over the entire inner surface of the uterus.

The problem is solved due to the fact that a device for stopping uterine bleeding, including a balloon and a delivery device and support in the form of a tubular elastic element, through which fluid is supplied from a reservoir to create pressure in the balloon,

contains a second outer balloon located outside the first balloon with a gap between them over the entire surface, made with perforations, an annular dispenser with axial holes through which the drug from the dispenser enters the gap between the first and second balloons, a sleeve on which the delivery device is worn and a support, and which is fixed to the annular distribution device.

The presence of a second outer balloon located outside the first balloon with a gap between them over the entire surface, made with perforations, and an annular dispenser with axial holes through which the medicine from the dispenser enters the gap between the first and second balloons, allows for uniform distribution of the medicine over the entire surface of the uterus, due to which a more reliable cessation of bleeding occurs.

The drawing shows a device for stopping uterine bleeding.

The device consists of:

1. The first (inner) balloon;

2. Second (outer) balloon;

3. Dispenser;

4 and 5. Elastic tubes;

6. Sleeve;

7. Annular distribution device with axial holes;

8. Threaded ring;

9. Delivery means - elastic tube;

10. Delivery means and supports in the form of a tubular elastic element.

11. Tank with sterile water;

12. Elastic tube for delivery of medication or saline solution;

13. Cover;

14. Electrovalve to which the drug dispenser 15 is connected;

15. Drug dispenser;

16. Electrovalve to which the dispenser 17 is connected;

17. Dispenser of physiological solution;

18. Control device;

19. Perforations in the second cylinder 2.

20. Protrusions on the first cylinder 1.

The device for stopping uterine bleeding contains two balloons, balloon 1 - internal and balloon 2 - external, which are connected to the dispenser 3 through an annular distribution device 7, in which axial holes are provided through which the drug or saline solution enters the gap between the first 1 and the second 2 balloons formed by protrusions 20 on the first balloon. Then, through the perforations 19 in the second balloon 2, they fall on the surface of the uterus in various places.

The sleeve 6 is attached to the annular distribution device 7 by means of a threaded ring 8. A delivery device is put on the sleeve 6 - an elastic tube 9, which creates the necessary rigidity necessary for the introduction of the instrument into the uterus. Through the elastic tube 10, put on the sleeve 6, liquid is supplied from the reservoir 11 to create pressure in the first balloon 1. Through the elastic tube 12, either saline or a drug is supplied alternately. The tube is on the cover 13.

Elastic tubes 4 and 5 lead to a liquid dispenser 3, to which a dispenser 15 with a drug is connected through an electrovalve 14, and a dispenser 17 with a saline solution is connected to an electrovalve 16. Medication and body fluid may mix at some point. In this case, there is a control device 18, which is connected to both dispensers 15 and 17 to coordinate their work.

The device works as follows.

Sterile fluid from reservoir 11 is supplied to the balloon 1 through the delivery means and supports in the form of a tubular elastic element 10 to create pressure in it. The created pressure in the balloon 1 is transmitted to the vessels of the uterus and promotes blood clotting and cessation of blood loss. In the second balloon 2, which is located outside the first balloon 1, through the axial openings of the annular dispenser 7, either saline is supplied from the dispenser 17 for washing the uterus, or a drug from the dispenser 15.

The second external balloon 2 is a perforated hole 19 through which saline or drug enters the uterus.

To prevent the balloons from sticking together, on the inside of the second balloon 2, projections can be provided over the entire surface, which provide a gap between the balloons and at the same time allow the drug to flow between the first 1 (inner) and the second 2 (outer) balloons.

Or it is possible to make the first balloon 1 with external projections.

Or it is possible to make the first balloon 1 with glued strips to provide gaps. It is also possible to provide a gap by placing the mesh between the two cylinders.

The supply of the drug or saline solution to the uterus is provided by an external control device 18, which, according to the established program, supplies the content of the reservoirs 15 or 17 in the required volumes and at the right time through the electrovalves 14 or 16. The operation of the dispensers 15 and 17 is coordinated by the control device 18.

First, the uterus is washed with saline. Decomposition products flow out. After that, the second dispenser 15 turns on and delivers the medicine. The operation of both dispensers is carried out according to the program of the control device 18.
