Vacuum assisted tissue treatment system

摘要

A system for stimulating healing of tissue at a wound site (12) is described comprising:
a porous pad (11);
a pump (14) for delivering a pressure and adapted to apply a variable reduced pressure to the wound site through said porous pad; and
a controller (84) regulating the pump to vary the pressure by comparing the pressure to a variable target pressure and changing the pressure in predefined pressure intervals between a first reduced pressure and a second reduced pressure in response to the comparison.
