Patent number: 6083171Abstract: A pulse wave propagation time is counted constantly. Not only it is judged whether or not a pulse wave propagation time change .DELTA.T exceeds a pulse wave propagation time change threshold .DELTA.Ts, but also it is judged whether or not cardiovascular dynamic changes .DELTA.HR, r.sub.1, r.sub.2 exceed thresholds thereof .DELTA.HRs, r.sub.1 s, r.sub.2 s, whereby a sudden turn for the worse in the blood pressure fluctuation of a subject is monitored. If any one of the changes exceeds the threshold thereof, a blood pressure measurement using a cuff 2 is made on the subject.Type: GrantFiled: November 1, 1996Date of Patent: July 4, 2000Assignee: Nihon Kohden CorporationInventors: Kohei Ono, Hiromitsu Kasuya, Yoshihiro Sugo, Takeshi Sohma, Hidehiro Hosaka

Patent number: 5876348Abstract: During a noninvasive blood pressure measurement using a cuff 2, a pulse wave propagation time T1 from the appearance of the peak value of an R wave in an electrocardiogram (ECG) waveform to the appearance of the bottom value of a pulse wave is counted, and a blood pressure value BP1 is calculated from a count result T1 and parameters .alpha., .beta. specific to a subject obtained during a pulse wave propagation time calibration. Then, the absolute value of a difference between the blood pressure value BP1 and a blood pressure value NIBP1 obtained by the noninvasive blood pressure measurement using the cuff 2 is calculated, and it is indeed whether or not the calculated absolute value is within a predetermined threshold.sub.-- BP. If the absolute value is judged to exceed the threshold.sub.-- BP, then blood pressure is measured again noninvasively using the cuff 2, and a blood pressure value NIBP1'obtained from such repeated measurement is displayed on a display 22.Type: GrantFiled: December 18, 1997Date of Patent: March 2, 1999Assignee: Nihon Kohden CorporationInventors: Yoshihiro Sugo, Takeshi Sohma, Hiromitsu Kasuya, Rie Tanaka

Patent number: 5755669Abstract: After an initial blood pressure measurement using a cuff 2 has been made, not only a pulse wave propagation time Tt is counted consecutively, but also a pulse wave propagation time change .DELTA.T is calculated every time the pulse wave propagation time Tt is counted and compared with a pulse wave propagation change threshold .DELTA.Ts. When the pulse wave propagation time change .DELTA.T exceeds the pulse wave propagation time change threshold .DELTA.Ts, not only a blood pressure value BPt is measured with the cuff 2, but also a pulse wave propagation time Tt.sub.1 is counted. If there are at least two sets of data, each set of data consisting of a blood pressure value BPt and a pulse wave propagation time Tt.sub.1, coefficients .alpha., .beta. specific to a subject are calculated from such two sets of data by a least-squares method. Then, the pulse wave propagation time change threshold .DELTA.Ts is calculated from the coefficient .alpha., and the current pulse wave propagation time change threshold .DELTA.Type: GrantFiled: April 30, 1997Date of Patent: May 26, 1998Assignee: Nihon Kohden CorporationInventors: Kohei Ono, Hiromitsu Kasuya, Yoshihiro Sugo, Takeshi Sohma, Wenxi Chen
