Prior to the description, as shown in FIGS. 4 and 7, the first light emitting devices 101, 102, 103, and 104 installed in the wristband 100 are arranged in a square or rhombus shape in the embodiment. However, the present invention is not limited to four, but two or more may be arranged in various forms.

The cuff band 100 is a member to be worn on the patient's cuff, preferably made of a metal or synthetic resin-based watch band type, it may be made of an elastic band type of rubber material to facilitate wearing on the cuff.

As shown in FIG. 4, the cuff band 100 is provided with a plurality of first light emitting devices 101, 102, 103, 104 and a first light receiving unit 110 on an inner circumferential surface of the cuff that contacts the wrist of the patient. The first light emitting devices 101, 102, 103 and 104 are infrared devices irradiated with infrared rays, and the infrared light emitted from the light emitting devices 101, 102, 103 and 104 is directed toward the arteries A of the wrist. do.

By activating (101, 102, 103, 104) one by one, the reference point is set again to track the first light emitting device 101 closest to the artery A, and the time setting can be controlled by a timer 240 to be described later. There will be.

As described above, when the reference points of the first light emitting devices 101, 102, 103, and 104 are continuously tracked, even if the position of the first light emitting device 101 set as the reference point is changed by the patient moving the arm (b) of FIG. As shown in Fig. 1), the accurate pulse rate value can be measured.

Next, the first surface electrode 120 and the second surface electrode 130 will be described.

The portion represented by the dotted dotted block is a value determined by the controller 200 as a normal signal.

Normal pulse rate is measured after the contractile action of the heart. However, when the patient speaks or coughs during the measurement, an abnormal pulse is detected which is not related to the export of the heart. When the controller 200 detects an abnormal pulse in the first light receiver 110, it is regarded as noise. Ignore it.

That is, the control unit 200 actually only contracts the pulse within the time considering the contraction point and pulse wave transmission time of the heart based on the electrocardiogram values measured from the first surface electrode 120 and the second surface electrode 130. The control unit 200 is characterized by the recognition of the pulse by the pulse, and other than the detected signal as a motion or other noise, and this feature is excluded from the influence of the movement or noise due to this feature to accurately change the blood pressure change It can be measured.
