Abstract
In a first peritoneal dialysis apparatus, a therapy start time (dialysis start time) is settable even in either a first therapy mode or a second therapy mode. The first therapy mode is adapted to calculate a total amount of dialysis fluid on the basis of an amount of infusion fluid, a staying time, and the number of cycles, and the second therapy mode is adapted to calculate a total amount of dialysis fluid and a staying time on the basis of a dialysis time, an amount of infusion fluid, and the number of cycles. In a second peritoneal dialysis apparatus, a fluid infusion time or a fluid drainage time is calculated on the basis of an amount of infusion fluid or an amount of drainage fluid and a fluid infusion rate or a fluid drainage rate, and if it is decided that fluid infusion or fluid drainage is performed for a time being twice or more the calculated fluid infusion time or fluid drainage time, an alarm indicating defective fluid infusion or defective fluid drainage is generated. In a third peritoneal dialysis apparatus, an instruction for temporary stoppage of therapy can be inputted during therapy, and a residual staying time based on the inputted instruction is displayed.
