SYSTEM AND METHOD FOR LOW PRESSURE APPLICATION TO TISSUE AREA Russian patent published in 2012 - IPC A61M1/00 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A pump comprises a case with its upper portion being compressible relatively to a lower portion of the case while in operation, a variable-volume chamber integrated in the case and manually compressible in a number of positions, a constant-volume chamber integrated in the case and connected to the variable-volume chamber, and a filter case assembly integrated in the case between the constant-volume chamber and the variable-volume chamber, and comprising a hydrophobic filter which prevents fluid from flowing into the variable-volume chamber. The constant-volume chamber has low pressure which is applied to a tissue area in response to motion of the variable-volume chamber from the compressed position specified from the number of positions, into the non-compressed position specified from the number of positions. There are disclosed a method for applying low pressure to the tissue area and versions of the pump differing by the design of the case and filters.

EFFECT: provided autonomous operation and eliminated infection.
