  • Patent number: 8303532
    Abstract: A peritoneal function testing apparatus tests the peritoneal function of a dialysis patient easily and with high accuracy. Standards of four kinetic parameters (CCr, Kt/V, MTACu, and MTACc) available in a definite dialysis guideline are computed in accordance with a relational expression, and a curve showing the relation between MTACu/c and the drained fluid volume is indicated in a graph together with the PET data of the patient which has been prepared separately. Thus, the peritoneal function can be evaluated based on the relative position of the patient's data and the curve showing the standard values in the graph.

  • Publication number: 20090271119
    Abstract: It is intended to provide a method whereby the peritoneal function of a dialysis patient can be tested by a relatively easy procedure and yet a high accuracy can be achieved compared with the existing methods, and an apparatus for the peritoneal function test by using the same. Standards of four kinetic parameters (CCr, Kt/V, MTACu, and MTACc) available in a definite dialysis guideline are computed in accordance with the relational expression (formula (7)). The curve showing the relation between MTACu/c thus obtained and the drained fluid volume is indicated in a graph together with the PET data of the patient which has been prepared separately. Thus, the peritoneal function can be evaluated based on the relative position of the patient's data and the curve showing the standard values in the graph.

  • Patent number: 7303541
    Abstract: The peritoneal function of a peritoneal dialysis patient is examined to evaluate the condition of the patient. An examining method comprises a step of alternately repeating introduction/drainage of a predetermined quantity of a peritoneal dialyzing fluid of an osmotic pressure and introduction/drainage of a predetermined quantity of another peritoneal dialyzing fluid of an osmotic pressure different from the former one, a step of examining the drain to determine the quantity of peritoneal dialyzing fluid staying in the abdominal cavity of the patient and the concentration of a solute of interest, a step of conducting a peritoneal equilibrium test, and a step of conducting a blood test to grasp the change of the state of the blood caused by the introduction and drainage. The blood test step is executed only once.
