METHOD FOR ARREST OF METRORRHAGIA AND DEVICE FOR ARREST OF METRORRHAGIA Russian patent published in 2009 - IPC A61M25/10 A61K33/14 A61K38/11 A61P15/00 A61P15/04 A61K31/197 

FIELD: medicine; gynaecology.

SUBSTANCE: hemostatics and uterotonic agents are parenterally introduced. Previously folded intrauterine rubber balloon catheter with delivery and support in the form of tubular element rounded at distal end with length that is comparable to but not less than total length of uterine cavity and vagina is introduced into cavity of birth canal. Irrigation and drain tubes from elastic shape-holding material are located on external surface of balloon. Length of tubes exceeds length of tubular element for delivery and support of balloon catheter with possibility of exit beyond the limits of birth canal - from vagina. Distal ends of tubes are rounded with openings on the surface for contents outlet and collection. One of tubes is arranged with the possibility of connection with syringe for introduction of hemostatic into uterine cavity, other tubes are connected with reservoir for collection of drained liquid. Tubular element for delivery and support of balloon catheter is connected with reservoir for filling of balloon catheter with sterile liquid, the second tube installed in reservoir above liquid level is connected to manometer, and pump for pressure charging is located at its end. This device is located from entry to vagina to uterus bottom, fixing proximal end of balloon catheter with tubes in entry to vagina. Then sterile physiological solution is pumped into catheter by means of pump until visually controlled bleeding is arrested. After bleeding has been stopped, pressure value is fixed, then pressure changes are registered in filled balloon catheter, at that pressure rise is treated as restoration of uterus contractive activity, afterwards pulled pressure is reduced in successive steps down to fixed value. If pressure value in catheter drops, it is increased up to fixed value. In both cases fixed pressure of bleeding arrest is maintained for at least 30 minutes, reduction is carried out in successive steps by 10 mm of mercury column every 5-10 minutes. Hemostatics are introduced into uterine cavity by irrigation tube in appropriate doses, then all tubes are isolated for the time sufficient for creation of blood clot. If no bleeding takes place through drain tubes in process of stepwise pressure reduction, pressure is dropped, liquid is removed from balloon catheter, and it is withdrawn outside.

EFFECT: fast and efficient arrest of metrorrhagia by coverage of the whole area of possible bleeding and simultaneous additional effect at local hemostasis by introduction of medicines into uterine cavity.
