You get a waveform that is almost similar to the QRS value of the electrocardiogram (ECG: Electrodiagram) measured by the device. In particular, the largest and sharpest R value is measured identically.

Accordingly, the ECG detected using the ECG and the induced potential difference may have the same QRS point (see FIG. 5) that causes heart contraction, thereby obtaining the same result when measuring the R-R interval.

That is, the present invention has the same performance as directly measuring the QRS point by directly attaching the surface electrode, so that it can be easily worn on the top of the garment, which is convenient and can reduce the risk of infection and measure the electrocardiogram value.

In addition, the gravity sensor 130, as shown in Figure 7, serves to detect the state of the patient with respect to gravity.

In more detail, when the belt is worn, the reference point is set to detect the patient lying down. As shown in FIG. 7A, when the patient is standing (upright) as the reference point, The gravity sensor 130 is set to coincide with the spine direction of the patient, that is, the up and down direction, and when a value orthogonal to the set reference point is detected by the gravity sensor 130, as shown in FIG. Will be detected as lying down.

In general, when the lying state is the least change in blood pressure, when the patient is lying so that the state of the patient is transmitted to the control unit 300 to be described later, the gravity sensor 130 as described above is the subject matter of the present invention The detailed description thereof will be omitted so as not to be ambiguous.

Next, the wrist band 200 will be described.

The cuff band 200 is a member worn on the wrist of the patient, serves to detect the pulse data of the patient by irradiating infrared rays, and can adjust the elastic band type or length of the rubber material to facilitate wearing on the wrist It is desirable to manufacture metal or leather watchband types.

As shown in FIG. 3, the wrist band 200 as described above is provided with a plurality of first light emitting devices 201, 202, 203, and 204 and a first light receiving part 210 on an inner circumferential surface of the wrist which is in contact with the wrist of the patient. The first light emitting devices 201, 202, 203, and 204 are infrared devices that are irradiated with infrared rays. The infrared light emitted from the first light emitting devices 201, 202, 203, and 204 may serve to arteries A of the wrist. Investigate towards.

As described above, the infrared light emitted from the first light emitting devices 201, 202, 203, and 204 toward the artery A is reflected and received by the first light receiving unit 210. It is possible to detect blood flow, that is, pulse rate.

In addition, the wristband 200 has a second amplifier 220 for amplifying the value of the pulse received by the first light receiving unit 210 as described above, and the second filtering for removing the noise mixed in the amplified value The unit 230 and a second eddy converter 240 for converting the noise is removed as a digital signal as described above is further included, the pulse value converted into a digital signal is transmitted to the controller 300 to be described later.

On the other hand, the wrist band 200 may be connected to the finger band 400, the finger band 400 is worn on the end of the finger is concentrated peripheral blood vessel to detect the blood volume of the peripheral blood vessel, The rate of change of blood volume is transmitted to the controller 300, which will be described later.

That is, the wrist band 200 detects the pulse rate of the wrist artery, and the finger band 400 detects the change in the volume of peripheral blood vessels at the fingertips.

In addition, the first light emitting devices 201, 202, 203, and 204 are activated so that all the first light emitting devices 201, 202, 203, and 204 are activated when irradiated with infrared rays, and irradiate infrared rays to the first light receiving unit 210. Although it is preferable to sum all the values received by the control unit 300 to be described later, the largest value among the plurality of first light emitting devices 201, 202, 203, and 204, that is, as shown in FIG. 6, Only one first light emitting device 201 disposed closest to the artery A may be activated.

As described above, when only one first light emitting device 201 is activated, the first light emitting devices 201, 202, 203, and 204 may be operated simultaneously to detect and calculate a plurality of signals.

For example, when all four first light emitting devices 201, 202, 203, and 204 are activated, four different pulse values are received by the first light receiving unit 220. Except for the pulse rate received from the first light emitting device 201, the pulse rate values detected by the remaining three first light emitting devices 202, 203, and 204 are almost insignificant, and thus a value close to noise is detected.

Accordingly, when only one first light emitting device 201 is activated, it may be accurately detected by the first light receiving unit 210 by setting the largest one pulse value as a reference point.

As described above in more detail for setting one first light emitting device 201 as a reference point, the controller 300 to be described later includes four first light emitting devices 201, 202, 203, and 204 one by one. It activates and measures the four pulse values input to the first light receiving unit 210, and sets the reference point so that only one of the first light emitting device 201, the largest value of which is input is activated and the remaining first light emitting device ( 202, 203, and 204 transition to the standby state.

Subsequently, after detecting the pulse rate using one first light emitting device 201 for a predetermined time, for example, 10 minutes using one first light emitting device 201, the four first light emitting devices ( By activating 201, 202, 203, and 204 one by one, the reference point is set again to track the first light emitting device 201 closest to the artery, and the time setting may be controlled by a timer 310 to be described later.

As described above, when the reference points of the first light emitting devices 201, 202, 203, and 204 are continuously tracked, even if the position of the first light emitting device 201 set as the reference point is changed by the patient moving the arm (b) of FIG. As shown in), there is a characteristic that can measure the accurate pulse rate value.

Next, with reference to Figure 8 will be described with respect to the flow of measuring the change in blood pressure according to the movement of the patient by using the blood pressure change measuring device for detecting the movement of the patient according to a preferred embodiment of the present invention.

First, the patient wears a top, and then wears a chest belt on the top of the top, so that the surface electrode 111 and the active electrode 112 are positioned near the heart so as to measure an accurate ECG value. In addition, the 3D acceleration sensor 120 and the gravity sensor 130 also wears a chest belt to detect the exact movement and condition of the patient.

Thereafter, the controller 300 compares the induced electrocardiogram and the pulse volume change rate of the peripheral blood vessel detected by the pulse band and the finger band detected by the wrist band 200 with each other to determine whether the signal detected by the wrist band 200 is normal. By setting the induced ECG value as a reference, only the pulse rate detected after the heart contraction point R is determined as a normal value.

At the same time, the control unit 300 compares the pulse rate detected by the wristband 200 with the value of blood volume detected by the finger band 400 and detects a change in blood pressure. Detected by the method.

After the contraction of the heart, the blood moves through the blood vessels, if the blood pressure is high blood speed is increased, if the blood pressure is low, the movement speed of the blood can be inferred by the change in blood pressure.

In addition, the control unit 300 is determined to be hypertension or hypotension because the change in blood pressure detected by the above method is out of a predetermined value, and the warning message of "is hypertension" or "hypertension" is the condition of such a patient.
