Residual pressure control in a compression device

摘要

RESIDUAL PRESSURE CONTROL IN A COMPRESSION DEVICE Abstract A method of controlling a compression device (1) controls a vent phase of a compression device (1) having an inflatable bladder (3) capable of being pressurized for applying compression to a part of a subject's body. The method includes delivering pressurized fluid from a source of pressurized fluid to a first inflatable bladder (3) disposed about a portion of the subject's body and venting the pressurized fluid from the first inflatable bladder (3) by opening a first valve (23). The method further includes monitoring fluid pressure in the first inflatable bladder (3) during the venting of the first inflatable bladder (3). Based at least in part on the monitored fluid pressure, the first valve (23) is selectively closed and selectively reopened to control fluid pressure in the first inflatable bladder (3) to remain within a desired residual pressure range.
