Device for correcting blood pressure waveform.

摘要

The waveform of a blood pressure of a patient is corrected by a pressure correcting mechanism (3) having an air chamber (9) with a volume ranging from 1 to 150 mu l and a resistance passage (10) having one end communicating with the air chamber (9) and the other end with a blood pressure measuring line (B). The resistance passage has a cross-sectional area ranging from 2000 to 160000 mu m<2> and a length ranging from 0.5 to 40 mm. A fluid such as a physiological saline solution filled in the blood pressure measuring line (B) can flow through the resistance passage (10) into the air chamber (9) to dampen an extraneous pressure wave transmitted through the blood pressure measuring line (3).
