Hemodialysis apparatus and method for hemodialysis

Abstract

The present invention relates to a blood dialysis apparatus, in which a plural number of adequate dialysis therapy data (time-series data), wherein an estimated dry weight is closely similar to the dry weight, are memorized and thus it can be easily determined whether or not the subsequent dialysis therapy process achieves adequate therapeutic effects closely similar to the dry weight, and a blood dialysis method. A blood dialysis apparatus comprising: a dialytic treatment unit by which water is removed in accordance with the water removal amount determined based on an estimated dry weight and dialysis therapy is conducted; a BV detection unit (9) by which BV of the blood under extracorporeal circulation is measured at multiple points through time in the course of the dialysis therapy by using the dialytic treatment unit to thereby give time-series data; a determination unit (10) by which it is determined whether or not the estimated dry weight is closely similar to the dry weight after the completion of the dialytic therapy by using the dialytic treatment unit to thereby determine the adequacy of the dialysis therapy; and a memory unit (11) by which a plural number of the time-series data of the dialysis therapy having been judged as adequate by the determination unit (10) can be memorized.

Description

technical field [0001] The present invention relates to a hemodialysis apparatus and a hemodialysis method for performing hemodialysis treatment and water removal while circulating blood of a patient extracorporeally. Background technique [0002] Generally, in dialysis treatment, the following hemodialysis apparatus is used, which includes a blood circuit for extracorporeal circulation of blood of a patient; a dialyzer connected to the blood circuit; a peristaltic blood pump; a dialysis apparatus main body, Dialysate is introduced or exported between it and the dialyzer, and water removal treatment can be performed while performing hemodialysis treatment. In addition, the blood circuit is mainly composed of an arterial side blood circuit with an arterial side puncture needle attached to the distal end, and a venous side blood circuit with a venous side puncture needle attached to the distal end. [0003] And, if the blood pump is driven in the state where the puncture need...

Problems solved by technology

[0005] However, when the amount of water to be removed (moisture removal amount) is large, the water removal rate must be accelerated, so there is a possibility that shock symptoms such as hypotension may often occur due to the patient's health condition.
