However, some configurations which are not related to the gist of the present invention may be omitted or compressed, but the configurations omitted are not necessarily those not necessary in the present invention, and they may be combined by a person having ordinary skill in the art to which the present invention belongs. .

1 is a perspective view illustrating a bio-signal measuring apparatus according to an embodiment of the present invention. As shown in FIG. 1, the bio-signal measuring apparatus 1 according to the embodiment of the present invention includes a wear band 10 and a watch-type measurement unit 20.

The wearing band 10 is intended to be worn on the wrist as a wristwatch, and is provided with fixing means 11 at both ends so as to be worn without falling out of the wrist. In FIG. 1, the fixing means 11 is embodied by a velcro, and the fixing means 11 may be provided in the form of a usual band, and the wearing band 10 itself may be formed in the form of a band having elasticity .

The clock-type measuring unit 20 is manufactured in such a form that the first measurement module 21, the connection unit 22, and the second measurement module 23 are hingedly folded or unfolded. Accordingly, when the bottom surface of the first measurement module 21 is folded while facing the upper surface of the second measurement module 23, the wear band 10 is fitted and fixed to the watch-type measurement unit 20 as shown in FIG. 1 . FIG. 3 shows a bio-signal measurement apparatus 1 according to the present embodiment worn in a clockwise fashion.

On the other hand, the time-of-day measuring unit 20 has means for measuring pulse rate and oxygen saturation. The configuration of the clock-type measuring unit 20 will be described in more detail with reference to FIG.

The first measurement module 21 includes a first light receiving section 21a, a display section 21b, a control section 21c, a memory 21d and a communication processing section 21e. The second measurement module 23 includes a first light emitting portion 23a, a second light emitting portion 23b, and a second light receiving portion 23c. The first measurement module 21, the connection portion 22 and the second measurement module 23 are physically connected and electrically connected.

The first light receiving portion 21a of the first measuring module 21 is provided on one side of the first measuring module 23 facing the second measuring module 23 so that the light emitted from the first light emitting portion 23a receives the transmitted light, do. The controller 21c calculates the degree of oxygen saturation according to the amount of transmitted light received by the first light receiving portion 21a and processes the calculated degree of oxygen saturation through the display portion 21b. The control unit 21c converts the state of the time-of-day measuring unit 20 into a clock mode or an oxygen saturation measurement mode according to the amount of transmitted light received by the first light receiving unit 21a.

The control unit 21c calculates the oxygen saturation and the pulse through the amount of light input from the first light receiving unit 21a and the second light receiving unit 23c and stores the information in the memory 21d or through the display unit 21b And determines whether the oxygen saturation and the pulse are in the normal state range. If the oxygen saturation and the pulse are not in the normal state, a signal is sent to the remote rescue system 4 through the communication processing unit 21e to notify the emergency. The specific function operation of the control unit 21c will be described below again.

The first light emitting portion 23a of the second measurement module 23 emits light of a specific wavelength for measuring oxygen saturation and the second light emitting portion 23b emits light of a specific wavelength for pulse measurement. The second light receiving section 23c receives the reflected light reflected from the measurement object by the light emitted from the second light emitting section 23b and transmits the reflected light to the control section 21c.

Each of the functional configurations of the first measurement module 21 and the second measurement module 23 described above will become more apparent from the description of the measurement process for each mode described below.

FIG. 3 shows a state in which the bio-signal measuring device 1 according to the embodiment of the present invention is worn for use as a watch.

The second measurement module 23 of the watch type measuring unit 20 is sandwiched between the wear band 10 of the back of the hand and the wrist while the wear band 10 is worn on the wrist, The wear band 10 is fixed between the first measurement module 21 and the second measurement module 23 in a state where the wear band 10 is sandwiched therebetween. In order to prevent the watch-type measuring unit 20 from being unfolded while being fixed to the wear band 10, an elastic material is provided at a portion where the first measurement module 21, the connection unit 22 and the second measurement module 23 are coupled .

When the clock-type measuring unit 20 is used in a clockwise state as shown in FIG. 3, the control unit 21c operates so that the time is displayed on the display unit 21b. Of course, if another key (not shown) is operated in this state, pulse or oxygen saturation information previously measured and stored in the memory 21d may be displayed on the display unit 21b.

4 is a diagram for explaining a state in which the oxygen saturation is measured using the bio-signal measuring apparatus 1 according to the embodiment of the present invention.

That is, the user pulls out the watch-type measuring unit 20 fixed to the wear band 10, inserts a finger between the first measurement module 21 and the second measurement module 23, and measures the oxygen saturation Set the mode. The first light emitting portion 23a emits light of a specific wavelength and the light emitted from the first light emitting portion 23a is received by the first light receiving portion 21a through the blood vessel of the finger.

The oxygen saturation in the blood is obtained by using the ratio of oxygenated hemoglobin to hemoglobin not bound to oxygen as variables. That is, the first light emitting portion 23a emits light having a wavelength of 660 nm, in which the light absorption of hemoglobin is larger than that of oxidized hemoglobin, and light having a wavelength of 940 nm, in which light absorption of oxidized hemoglobin is greater than that of hemoglobin, , The control section 21c can calculate the oxygen saturation from the ratio of the transmittances to the two wavelengths.

At this time, the control unit 21c also calculates the pulse rate by changing the value of the amount of light received by the first light receiving unit 21a. In other words, the blood flow changes according to the heartbeat. When the light is irradiated on the blood vessel, AC component appears in the light transmitted through the blood vessel. By measuring the number of peaks per minute of this signal, the pulse can be calculated.

The oxygen saturation information and the pulse information thus calculated are outputted through the display unit 21b and can be immediately checked by the user or the guardian and stored in the memory 21d.

4, after the measurement of the oxygen saturation is completed and the watch-type measuring unit 20 is again inserted into the wear band 10 as shown in FIG. 3, the light emitted from the first light emitting unit 23a is shaded by the wear band 10 The light can not be received by the first light receiving portion 21a. Therefore, when the amount of light received by the first light receiving portion 21a is less than a preset reference value in the state of the oxygen saturation measurement mode, the control unit 21c immediately switches to the watch mode, thereby preventing unnecessary power waste due to the light emission.

5 is a diagram for explaining a state of measuring a pulse using the bio-signal measuring apparatus 1 according to the embodiment of the present invention.

That is, as shown in FIG. 4, the pulse is also calculated in the process of measuring the oxygen saturation. However, in the state where the watch-type measuring unit 20 is attached to the wear band 10 as shown in FIG. 5, will be. At this time, it is preferable to adjust the position of the time-of-day measuring unit 20 so that the second measurement module 23 is located at the lower part of the wrist close to the arterial blood.

And the second light emitting portion 23b and the second light receiving portion 23c are located at a portion where the second measurement module 23 of the watch-type measurement portion 20 faces the skin.

The second light emitting portion 23b emits light having a wavelength of about 640 nm and the light emitted from the second light emitting portion 23b is reflected by the blood vessel and received by the second light receiving portion 23c. The light amount information of the light received by the second light receiving section 23c is transmitted to the control section 21c and the control section 21c calculates the pulse through the change of the light amount value inputted to the second light receiving section 23c, ).

Meanwhile, in the bio-signal measuring apparatus 1 described above, a window is provided on the surfaces of the light emitting portions 23a and 23b and the light receiving portions 21a and 23c to prevent the sensors from directly touching the skin.

The method of measuring oxygen saturation and pulse using the bio-signal measuring apparatus 1 according to the embodiment of the present invention has been described above. The measured bio-information is displayed on the display unit 21b provided in the first measurement module 21, But it is also possible to systematically manage health by being transmitted to the relay means 2 such as a smart phone, a tablet PC, a desktop computer or the like as shown in FIG. That is, the communication processing unit 21e provided in the first measurement module 21 can transmit the oxygen saturation information and the pulse information stored in the memory 21d to the relay unit 2 by using the Zigbee communication, the Bluetooth communication, or the RF communication method , And the relay means (2) can clearly arrange and check the individual's health condition through a dedicated program.

In addition, the biometric information of the individual transmitted to the relay means 2 is transmitted to the rescue system 4 such as a hospital or a fire department through the communication network 3, so that quick rescue can be made when the health state deteriorates. In other words, when the controller 21c of the first measurement module 21 determines that the measured oxygen saturation information and the pulse information are out of the predetermined range, the controller 21c processes the signal to immediately notify the emergency through the communication processing unit 21e, The emergency signal is transmitted to the rescued system 4 via the relay means 2 and the communication network 3, so that the emergency signal can be promptly treated by an expert when the health condition of the elderly living alone becomes worse.

As described above in detail, according to the present invention, the user can normally use the watch as a wristwatch, or the user can check the pulse at any time, or can separate the watch-type measuring unit 20 and fit the finger to the finger to measure the oxygen saturation. That is, even if a separate pulse oximeter is not provided, it is possible to check the health state by measuring the pulse and oxygen saturation through the time-of-day measuring unit 20. In addition, the measured pulse and oxygen saturation information can be transmitted to a smartphone or a PC to enable a systematic health check. In addition, when the health condition deteriorates, the system notifies the rescue system 4 of the fire department or hospital through the communication network 3, Actions may be possible.

Although not shown in the figure, the second measurement module 23 of the watch-type measurement unit 20 is further provided with a temperature sensor (not shown) to measure the body temperature of the user in real time and store it in the memory 21d, The communication unit 21c may process the emergency signal in conjunction with the communication processing unit 21e so that the emergency signal is output when the body temperature is out of a certain range.

It is a matter of course that the watch-type measuring unit 20 is provided with a rechargeable or replaceable battery for supplying power to each element.
