PRESSURE ADJUSTMENT METHOD Russian patent published in 2017 - IPC A61F2/80 

FIELD: medicine.

SUBSTANCE: invention relates to a method for pressure adjustment in the volume (52) between the prosthetic body (50) and the liner (48) or the structural element of the prosthetic system and the amputation stump in a vacuum system to secure the prosthetic system. The method comprises the steps of: a) determination of the pressure values (4) that are a pressure measure in the volume (52) at different times, and recording of certain pressure values, b) determination of the maximum (12) and minimum value (14) among the recorded pressure values, c) determination of the difference in the maximum value (12) and the minimum value (14), d) comparison of the difference value (16) and a predetermined first limit value, and e) pump activation to pump the fluid out of the volume (52) if the difference value (16) is higher than the predetermined first limit value. The first limit value does not depend on the state of motion and does not depend on the absolute value of pressure acting in the volume.

EFFECT: simplified pressure adjustment in the vacuum system volume in order to create the optimum pressure for the corresponding state.
