8. A waste evacuator for vacating waste products from a stoma comprising an inlet adapted to seal over the stoma;
-
an outlet;
a motor; and
a drive means for drawing the waste products held in a shortened bowel through the inlet and out of the outlet of the evacuator;
wherein the drive means comprises at least two arms which are rotated within a substantially circular chamber having an outer wall; a flexible plastic tubing which lies in the chamber, forming the inlet and the outlet of the evacuator, and is compressed against the wall of the chamber by the at least two arms, wherein as the arms rotate within the chamber, the arms move along said flexible plastics tubing, which moves waste material along said flexible plastics tubing by flow induction, wherein the motor operates said drive means when the inlet is sealed over the stoma.
