Patent number: 6453184Abstract: A red light and an infrared light which are emitted from a light emitting portion 2 are transmitted through a fingertip 4 of a subject and are converted into electric signals by a light receiving portion 3. The respective signals are separated and amplified and are then sent to a CPU 8. In the CPU 8, the input signals are divided into D.C. components DC1 and DC2 and A.C. components AC1 and AC2, changes &Dgr;A1=(AC/DC) 1 and &Dgr;A2=(AC/DC)2 in an absorbance are calculated, high frequency components thereof are extracted, a mutual ratio &PSgr; is calculated, and a noise removing waveform is calculated based thereon. Based on the noise removing waveform, a pulse wave is detected, a pulse rate is calculated, a display wave form is calculated and an oxygen saturation is calculated. These are displayed through a display unit 11.Type: GrantFiled: September 13, 2000Date of Patent: September 17, 2002Assignee: Nihon Kohden CorporationInventors: Mitsushi Hyogo, Teiji Ukawa, Hideo Ozawa

Patent number: 6257720Abstract: A pair of eyeglasses as provided with a mechanism on the nose bridge making it possible to turn one of the glasses around. A side piece attached thereto turns over together with one of the glasses, with the result that both of the eyepieces will be displaced over the glasses on both sides so as to protect the glasses from impact and the like when folded. Located within the bridge nose main body is a screw surrounded by a spring. At each end of the screw there are washers which provide for ease of movement between the spring and the screw. The spring is under compression at all times. Still further, the screw is tightly thread fitted into the connecting portion of the bridge so as to prevent loosening.Type: GrantFiled: April 6, 2000Date of Patent: July 10, 2001Assignee: Mitani USA, Inc.Inventor: Hideo Ozawa

Patent number: 6154667Abstract: A movable mechanism (3) moves a first housing (1) having a light emitting element (4) mounted thereon and a second housing (2) having a photo sensing element (5) mounted thereon in a state that those housings are parallel to each other. The movable mechanism (3) includes a pair of knobs (15A and 15B) and a spring (11) urging those knobs to move apart from each other. When the knobs (15A and 15B), while resisting the force of the spring (11), are pressed so as to make a mutual approach of those knobs, the first housing (1) and the second housing (2) are moved apart from each other. At this time, a finger of a patient is placed between the housings, and an operator gradually lessens his force applied to the knobs (15A and 15B) and reduces the force to zero. Then, the finger is held between the first housing (1) and the second housing (2). In this case, the orientations of the axes of the light emitting element (4) and the photo sensing element (5) are variable irrespective of the thickness of the finger.Type: GrantFiled: December 28, 1998Date of Patent: November 28, 2000Assignee: Nihon Kohden CorporationInventors: Hiroko Miura, Noriaki Todokoro, Hideo Ozawa

Patent number: 5255686Abstract: In a continuous noninvasive blood pressure measuring apparatus, a systolic pressure, diastolic pressure, and mean arterial pressure for calibration are measured according to the output of a pressure sensor, a cuff pressure is set lower than the diastolic pressure by a cuff pressure control section, and a reference pulse wave is obtained from the arithmetic means of a plurality of cuff pulse waves. A CPU calculates the peak value and the bottom value of the reference pulse wave, and a cuff pressure mean value corresponding to the D.C. component of the reference pulse wave, and further calculates coefficients which are used to allow the peak value, bottom value and cuff pressure mean value thus obtained to correspond to correspond to the systolic pressure, diastolic pressure, and mean arterial pressure, respectively.Type: GrantFiled: July 2, 1992Date of Patent: October 26, 1993Assignee: Nihon Kohden CorporationInventors: Sunao Takeda, Hideo Ozawa, Mitsushi Hyogo, Yoshinobu Nakae
