METHOD OF UMBILICAL VEIN BOUGIENAGE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely, abdominal surgery, and can be used in bougienage and subsequent cannulation of the umbilical vein in a widespread peritonitis. Method of umbilical vein bougienage involves transumbilical infusion. In the preoperative period, the patient's somatotype is determined before bougienage: dolichomorphic, mesomorphic or brachiomorphic, for which the angle of the umbilical vein in the portal vein is examined. In this case, the dolichomorph type corresponds to the angle of the umbilical vein in the portal in 98±7.2 degrees, mesomorphic – 125.4±13.6 deg. and brachiomorphic – 144.1±5.3 deg. For bougienage use bougie with a certain, depending on the selected somatotype, the angle of bending of the working rod. Selected moist bougie is introduced into the lumen of the vein by rotational-translational movements towards the portal vein until a sensation of "failure" occurs. Umbilical vein bougienage device comprises a removable handle and a working part in the form of a curved metal rod with a rounded distal end, curved at an angle of 98, 125 and 145 degrees, respectively, the angles of the umbilical vein in the portal vein in patients dolichomorphic, mesomorphic and brachiomorphic somatotypes.

EFFECT: group of inventions provides a decrease in the degree of traumatism in the treatment effect.
