Blood purification apparatus
First Claim
1. A blood purification apparatus comprising:
- an extracorporeal circulation system, a blood purifier provided in said system for purifying blood by dialysis or filtration through a semipermeable membrane,a circulating blood volume measuring instrument connected to said extracorporeal circulation system for measuring changes in the circulating blood volume within a patient'"'"'s body,a control section connected to said circulating blood volume measuring instrument, comprising a memory for storing a program for a pattern of changes in the circulating blood volume during blood purification, said program being matched to the condition of the patient, anda regulator connected to said extracorporeal circulation system and said control section, for controlling the circulating blood volume, said regulator being controlled by said control section on the basis of the circulating blood volume measured during blood purification and the programmed amount,whereby optimum blood purification is carried out while maintaining the circulating blood volume at a prescribed level.
