Automatic detection of the abdominal cavity emptying dialysis

The present invention discloses a method for automatically detecting celiac emptying peritoneal dialysis, of the drainage flow is first sampled value per share, and then the flow of neighboring strands comparing the difference value, the absolute value of the difference is referred δi, (1 ) when 0 δi =, i.e. the drainage flow without change in value, drainage is normal; (2) when δi> 0, and Li + 1 ≠ 0, δi + 1 = 0, for n> i + 1, if δn> 0, δn + 1 = 0, Ln + 1 = 0, an injection of peritoneal dialysate, if the injection flow, the liquid is emptied, otherwise pipe blockage; if δn> 0, δn + 1 = 0, Ln + 1 ≠ 0, continue comparing the difference; (3) when δi> 0 and Li + 1 = 0, the position is not correct or pipe plug. The present invention shares the drainage flow rate through each of the samples of the automated peritoneal dialysis apparatus of the comparative analysis can accurately determine whether the patient abdominal evacuation, pipe blockage, patient position three bad state.
