Dean Kamen, Geoffrey P Spencer, Douglas E Vincent: Peritoneal dialysis systems employing a liquid distribution and pumping cassette that emulates gravity flow. Deka Products Partnership, Charles R Mattenson, Thomas S Borecki, Daniel D Ryan, September 27, 1994: US05350357 (347 worldwide citation)

Peritoneal dialysis systems apply fluid pressure to move liquid. The systems can emulate either a fixed head height condition or different head height conditions, independent of the actual head height differential between the patient's peritoneal cavity and the external liquid source or destination. ...
