METHOD FOR MODELING TRUE STRAIN PRESSURE ONTO LARGE INTESTINAL WALL IN CASE OF PNEUMOCOMPRESSION Russian patent published in 2005 - IPC

FIELD: experimental medicine, juvenile surgery.

SUBSTANCE: the present innovation deals with intestinal invagination in children. One should force the air by dosages into large intestine of experimental animal. Moreover, it is necessary to perform cross-sectional access into abdominal cavity. Then one should tighten small intestine in area of ileocecal valve, introduce a balloon-catheter into right-hand subhepatic space to place it in abdominal cavity being perpendicular to large intestine, then one should squeeze anal opening manually and increase intraintestinal pressure up to 200 mm mercury column. One should conclude upon strain pressure onto large intestinal wall by the difference of intestinal pressure and that of in balloon-catheter. The method enables to model strain pressure onto intestinal wall being close to natural one in case of pneumocompression at conservative disinvagination.

EFFECT: higher efficiency of modeling.
