Central blood pressure waveform estimation device and peripheral blood pressure waveform detection device

A central blood pressure waveform estimation device comprising:

• a pulse wave detection section which non-invasively detects a peripheral pulse wave;
• a transfer function storage section which stores a transfer function calculated in advance based on a waveform of the peripheral pulse wave detected previously and a central blood pressure waveform corresponding to the peripheral pulse waveform;
• and
• a central blood pressure waveform calculation section which calculates a central blood pressure waveform corresponding to a waveform of a peripheral pulse wave newly detected by the pulse wave detection section, based on the newly-detected peripheral pulse waveform and the transfer function.

A central blood pressure waveform estimation device comprising:

• a pulse wave detection section which non-invasively detects a peripheral pulse wave;
• a blood pressure measurement section which measures a blood pressure in an area near a portion in which a peripheral pulse wave is detected by the pulse wave detection section;
• a conversion section which converts a waveform of the peripheral pulse wave detected by the pulse wave detection section into a peripheral blood pressure waveform using a value of the blood pressure measured by the blood pressure measurement section;
• a transfer function storage section which stores a transfer function calculated in advance based on the peripheral blood pressure waveform obtained by the conversion section and a central blood pressure waveform corresponding to the peripheral blood pressure waveform;
• and
• a central blood pressure waveform calculation section which calculates a central blood pressure waveform corresponding to a peripheral blood pressure waveform obtained by converting a waveform of a pulse wave newly detected by the pulse wave detection section using the conversion section, based on the peripheral blood pressure waveform and the transfer function.
