<p>An automatic exchanger for peritoneal dialysis, wherein an end portion of a peritoneal dialysis circuit having a dialyzing fluid bag and a drainage bag fitted to the circuit and having a branch portion is connected to and separated from an end portion of a tube on the patient side, a stored fluid is discharged outside the body and a fresh dialyzing fluid is injected into the abdominal cavity of the patient in order to exchange the peritoneal dialyzing fluid stored in the abdominal cavity of the patient with a fresh peritoneal dialyzing fluid, comprising a plurality of means for conducting an operation (A) for connecting the end portion of the tube on the patient side to the end portion of the peritoneal dialysis circuit, an operation (B) for injecting and discharging the liquids and an operation (C) for separating the end portions from each other and fitting a closing member to the end portion of the tube on the patient side, respectively, and control means so constituted as to conduct automatically the operations (A) and (C) and to conduct continuously each operation. The apparatus is simple in construction, can easily fit and remove the tubes, can easily replace the injection/discharge fluids, can prevent an erroneous operation by an operator and can reduce the possibility of infection.</p> |
