Title:
TREATMENT APPARATUS FOR EXTRACORPOREAL CIRCULATION BLOOD
Document Type and Number:
Japanese Patent JPS63122462
Kind Code:
A
Abstract:
The invention relates to a method and a device for removing heat from blood in the extracorporeal circulatory system, particularly during haemodialysis or haemofiltration, there being arranged, at least in the arterial part of the extracorporeal circulatory system (2), a temperature sensor (206) which measures the blood temperature, which correlates with the body temperature; and a regulating arrangement (106) is provided which, as a function of the measured blood temperature, controls the dialysis fluid temperature or substituate temperature in such a way that the blood temperature remains constant with respect to the initial value or assumes a predetermined value. A second temperature sensor (207) in the venous part of the extracorporeal circulatory system (2) makes it possible, given a knowledge of the blood flow, which is generally predetermined, to calculate precisely the heat removal, which the patient is experiencing, without it being necessary to know in detail the parameters of the extracorporeal circulatory system (2) and the temperatures of the dialysis fluid or substituate and the environment.
