METHOD FOR MEASURING ABDOMINAL PRESSURE Russian patent published in 2014 - IPC A61B5/03 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. Measuring an abdominal pressure is ensured by using an elastic membrane, covering a plate. A cavity between the membrane and the plate is connected by a three-way port to an air injection device and a blood measuring apparatus. The membrane hermetically closing the plate is pressed with using a handle connected to the plate with a certain force to an abdominal surface so that the plate contacts the abdominal wall completely. That is combined with closing an electric circuit, and a lamp flashes on so that the membrane curvature is equal to zero, and the contacts are closed, and a pressure in the cavity between the membrane and the plate is less than that in the abdominal cavity. Further, air is slowly injected into the cavity between the membrane and the plate until the pressure in the cavity between the membrane and the plate is equal to and slightly higher than that in the abdominal cavity - at the moment, the contacts open, the lamp flashes down, and the measured pressure in the cavity between the membrane and the plate is equal to that in the abdominal cavity.

EFFECT: invention enables implementing simple, non-invasive method for measuring the abdominal pressure ensured by applying a sensitive element to the abdominal cavity.
