Abstract
A blood purification method that purifies blood taken from a body by blood dialysis or by hemodiafiltration includes the step of changing an osmotic pressure of the blood to an increasing condition until a blood volume (BV level) attains a standard blood volume, in a former part of a blood purification process and the step of maintaining a standard blood volume and periodically changing the osmotic pressure of the blood in a later part of the blood purification process.
Claims7
A blood purification method that purifies blood taken from a body by blood dialysis or by hemodiafiltration, comprising:
- purifying blood maintaining an osmotic pressure of the blood at an increased level until a blood volume (BV level) attains a preset patient's standard blood volume, in a former part of a blood purification process;
- and
- maintaining the preset patient's standard blood volume and periodically changing the osmotic pressure of the blood by injecting alternately a high-concentration electrolyte liquid sufficient to increase the osmotic pressure of the blood and a low-concentration electrolyte liquid sufficient to decrease the osmotic pressure of the blood in a latter part of the blood purification process.
