The present invention relates to a wearable pulsator and a remote pulsation system using the same, and more particularly, to a structure of a wearable pulsator capable of measuring the spatial characteristics non-invasive pulse wave, and a remote pulsation system and a remote pulsation method using the same will be.

Most of the pulses currently used for medical use are invasive sensors that directly detect blood pressure changes by injecting tubes into blood vessels or non-invasive pulses using pressure sensors.

In particular, a pulsator using a pressure sensor has been studied a lot because of the non-invasive, among them Korean Patent Publication No. 2001-0028668 (Medical Pulse Sensor), Korean Patent Publication No. 2002-0096224 (Arterial Artery Vibrator) and Korean Utility Model Registration No. 20-0358195 (pulse wave measuring device).

The Korean Patent Publication No. 2001-0028668 (Medical Pulse Sensor) is a silicon film (1) that is in close contact with the skin of the radial artery and seals the air layer so as to detect a pressure change of the air layer due to pulse wave vibration as shown in FIG. A pressure sensing sensor (4) comprising a pressure sensing unit (3) comprising a silicon gel (2) for transmitting a pressure change of the air layer and a pressure measuring plate (3) for measuring a pressure change transmitted by the silicon gel; A silicone rubber (5) which is drilled in accordance with the size of the pressure sensing unit to surround the pressure sensing unit and attached to the front of the pressure sensing sensor (4) to fix the pressure sensing sensor (4) to the skin of the subject to be diagnosed; By including a reinforcing plastic plate (6) attached to the rear of the pressure sensor (4) to vary the pressure applied from the rear to the skin of the subject through the pressure sensor (4), Placing the silicon film (1) and the silicone gel (2) in front of the pressure measuring plate (3) is a conventional vein detection site is a metal effect to remove the cold feeling and unnecessary irritation to the human body, but unnecessary air tightly sealed and closed By indirectly transferring the pressure change of the air layer to the pressure measurement plate could not measure the exact vein, there was a problem that can not measure quickly by accurately pinpointing the position of the different veins per person.

In order to improve the above problems and mechanically implement the manner in which the oriental medicine is pulsating, that is, the coronary projection on the radial artery as the "tube", and the "chamber" 1 to 1.3 cm away from the tube toward the palm of the tube, Classify the chuck as 1 ~ 1.3 cm away from the elbow, and place three fingers around the examinee's middle finger and apply a slight force The conventional method of measuring the pulse wave by dividing the applied state (called "negative"), the more applied force (called "heavy"), and the slightly loosened state (called "needle") into one pressure sensor Mechanical implementation (Korean Patent Publication No. 2002-0096224), or three pressure sensors to measure the "chon", "tube", "chuck" site at the same time (Korean Utility Model Registration No. 20-0358195).

However, the above technologies are all using a pressure sensor such as a piezoelectric element, there have been the following problems.

First, although the temporal characteristics of the pulse could be grasped to some extent by measuring the change amount (waveform) of the pulse pressure by the pressure sensor, the pulse, such as the depth at which the more important pulse is detected, the width (width), the detected length, and the like, are detected. The spatial characteristics of the 3D shape of the Mac is difficult to grasp with the above technique.

Therefore, as shown in FIG. 2, among the 28 types of veins covered by the conventional pulses, the veins that can be identified by the above technique are only seven types related to the temporal characteristics (eg, veins, sacks, tachycardia, shovels, tactile veins, veins, and veins). There have been certain limits to replacing traditional pulses.

Secondly, products for grasping the spatial characteristics of the Mac using the pressure sensor technology have recently been made, but there is a limit in the spatial arrangement (integration) of the pressure sensor, so that the minimum spatial information of the Mac through excessive interpolation There is a problem that you have to get.

Third, in order to properly measure the spatial characteristics of the vein, the sensor must accurately locate the radial artery, but there is a problem that it takes a considerable time to search the pulsation site because only a few pressure sensors can not properly locate the center of the artery.

Fourth, there is a problem in that the application to the wearable pulsator is limited because it is impossible to measure the pulse while wearing it because it is vulnerable to movement noise due to the characteristics of the pressure sensor.

Finally, most pressure sensors are provided in the measuring means made of a rigid body, there is a problem that the pain caused by the applied pressure during the measurement.

On the other hand, if the pulse generator is implemented close to the traditional pulse and wearing it, as shown in Figure 3, even if the diagnosis can not diagnose even the area that can not be diagnosed by modern medical sensing, depending on the monitoring period, can be close to the traditional pulse Of course, there are few examples of developing a wearable device.

In Figure 3, "關 ↑" is the increase in the strength of the vessels, "寸 關 尺 强弱" is to compare the strength of the coronary vein is to diagnose the constitution, and other Chinese words represent 28 kinds of veins (see Fig. 2) With modern medical sensing methods, "PWV" is Pulse Wave Velocity, "RI" is Resistance Index, "HR" is Heart Rate, and "EEG" is Electro Encephalo. Gram), "HRV" represents Heart Rate Variability, "pre" represents Pregnancy, and "Flow" represents Blood Flow.

Furthermore, due to the difficulty of developing a wearable pulse generator that can be close to the conventional pulse, even though the Internet and communication technology have developed recently, the remote pulse system and remote pulse method using the pulse wave have not been properly developed. Efficient use of is in a long way.

Accordingly, an object of the present invention is to provide a wearable pulsator capable of pulsing closer to a traditional pulsation in order to solve the problems of the conventional pulsator as described above, and to provide a remote pulsation system and a remote pulsation method using the same. have.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

[Wearing type On the pulse  1st on Example ]

Wearable pulsator according to the present invention, basically, as shown in Figure 4, the belt-shaped or ring-shaped wearing means 140, the sensor unit 110 is located on one side of the wearing means to measure the pulse wave, in the sensor unit In the wearable pulse generator 100 including the data processing unit 120 for processing the measured pulse wave data, the sensor unit 110, as shown in Figure 5a, the magnetic material in contact with the skin of the position to be measured the pulse wave Skin contact portion 10 formed with; A pulse wave sensor unit 20 formed in an array form using a magnetic element such as a GMR element or an MTJ element spaced apart from the upper portion of the skin contact unit as a unit cell 22; It comprises a spaced apart space portion 30 to form a predetermined space between the skin contact portion 10 and the pulse wave detection sensor unit 20.

The key feature of the present embodiment is the skin contact part 10 formed of the magnetic body of the sensor unit 110, the pulse wave sensor unit 20 having a magnetic element such as a GMR element or an MTJ element in an array form, and a predetermined distance therebetween. It consists of a spaced space portion 30 to form a space, the magnetic body of the skin contact portion 10 receives the pulsation caused by the radial artery to change the magnetic field (magnetic field) applied to the magnetic element and the magnetic element is By detecting the change in the magnetic field, the contrary is to accurately identify the pulsation of the radial artery.

Therefore, the following matters should be considered to implement this embodiment.

First, the magnetic body of the skin contact portion 10 is a nano-magnetic particle in the form of a sub-micron-sized magnetic nanobead (sub-micron) that can facilitate the positional change according to the vibration of the pulse or a small permanent magnet or It is preferable to use an ultra-thin magnetic material made of a flexible ribbon magnetic pad.

More specifically, the nano magnetic particles are those having a diameter of 10 to 100 nm, and the small permanent magnets are disc magnets having a diameter of 1 to 3 mm and a thickness of 0.3 to 1 mm, and the ribbon magnetic. In the case of a pad, each having a thickness of 1 mm or less is preferable.

In addition, the nano-magnetic particles, disk-shaped magnets and ribbon-shaped magnetic pad is Nd, Co, Fe ₃ O ₄ and Fe ₂ O ₃ It is preferable to include any one or more selected from. In particular, the neodymium magnet (Nd-Fe-B Magnet) containing Nd, a rare earth metal, is obtained by grinding Nd and B after powder metallurgy molding. Therefore, it is more preferable to use this.

When the magnetic body of the skin contacting portion 10 is a ribbon magnetic pad, it is more preferable that the magnetic body is a plastic magnet having a magnetic field strength of about 200 to 300 Oe even at a distance of 3 mm, and the size thereof is the pulse wave sensor unit ( It is determined according to 20), but may be formed as five stripes of 1.0 mm in width and 12 mm in length. In this case, there is an advantage in that the skin contact part 10 can be fixed by the stripe groove of the magnetic pad.

In particular, the contact surface in contact with the skin of the skin contact portion 10 is preferably made of a soft material so that the shape of the skin surface is not pressed.

Next, the unit cell 22 of the array of pulse wave sensor units 20 may be used in the present embodiment as long as it has any structure as long as it is a magnetic element that responds to a change in an external magnetic field, such as a GMR element or an MTJ element. have.

Many of these devices have already been studied by semiconductor memory manufacturers and the like as next-generation memory devices (US Patent No. 5,520,090, US Patent No. 5650958, etc.). Therefore, only the content related to this embodiment is mentioned here briefly.

The GMR element used as the unit cell 22 of the present embodiment is generally referred to as an SV sensor exhibiting a spin valve (SV) effect. As shown in FIG. 5B, an antiferromagnetic layer is usually provided with a nonmagnetic layer 225 interposed therebetween. It consists of a pinned layer 226 magnetized in a specific direction by an antiferromagnetic layer and a free layer 224 that freely changes its magnetization direction in response to an external magnetic field, with longitudinal bias on each layer. A conductive layer for providing a further is formed at each end (222, 228) of the fixed ferromagnetic layer 226 and the variable ferromagnetic layer 224, and the current source 24 through the two conductive layers (222, 228) The signal detector 26 is electrically connected to sense the resistance of the GMR element.

As shown in FIG. 5C, when the magnetization direction 224 ′ of the variable ferromagnetic layer is changed to become the same as the magnetization direction 226 ′ of the fixed ferromagnetic layer, the magnetoresistance MR is performed. When the magnetization direction becomes small and becomes different from the magnetization direction 226 'of the fixed ferromagnetic layer, the magnetoresistance MR becomes large.

As a result, the present embodiment uses the operating characteristics of the GMR element as described above, and when the magnetic body of the skin contact portion 10 moves in accordance with the pulsation of the radial artery, the magnetic field is changed by the magnetic body. The variable ferromagnetic layer 224 of the GMR element senses and responds, and the response of the variable ferromagnetic layer 224 is represented as an electrical signal (voltage, etc.) due to a change in magnetoresistance in the external signal detector 26. By analyzing the signal of the external signal detector 26 three-dimensionally, it is possible to accurately grasp the pulsation of the artery.

On the other hand, the MTJ element used as the unit cell 22 of this embodiment is composed of two ferromagnetic layers separated from each other with an insulating tunnel barrier layer instead of the nonmagnetic layer in the GMR element. The tunnel barrier layer should be thin enough to cause quantum mechanical tunneling of the charge carriers between the ferromagnetic layers. In this case, since tunneling depends on the magnetization directions of the two ferromagnetic layers, one of the two ferromagnetic layers is a fixed ferromagnetic layer in which the magnetization direction is not affected by the external magnetic field, and the other is the magnetization direction influencing the external magnetic field. If the external magnetic field (signal) changes the magnetization direction of the variable ferromagnetic layer, it affects the tunneling of the charge carriers to the insulated tunnel barrier layer, which in turn changes the resistance of the MTJ element. This is detected by a signal such as a voltage.

Therefore, the MTJ element may also be used as a sensor for detecting a change in the magnetic field caused by the magnetic body of the skin contact portion 10 moving according to the pulsation of the radial artery. Other magnetic elements can also be replaced within the spirit of the present invention.

The pulse wave sensor 20 according to the present embodiment uses magnetic elements such as the GMR element or the MTJ element as the unit cell 22, and arranges them in an array form as shown in FIG. 5D.

The specific array type can be implemented in various ways depending on the purpose of measuring the pulse wave, but in order to obtain all the pulses according to the traditional Chinese doctor's pulse method, it is divided into three parts so as to correspond to the "chon", "pipe", and "chuck" parts. It is preferable to arrange the unit cells in an M x N form (for example, 2 x 5 or 3 x 6, etc.) and package them.

In addition, the size of the unit cell 22 of the pulse wave sensor 20 may vary depending on the process technology and the degree of integration, but preferably about 1.0 mm x 2.0 mm.

As a result, by properly arranging the fine unit cells 22 of the pulse wave sensor 20 in an array form as in the present embodiment, the pulse width, the length of the pulse, It can measure the depth of contact of the Mac, so you can fully understand the spatial characteristics of the Mac.

In addition, it is preferable that the space | interval space part 30 of this embodiment is made into the constant pressure chamber which maintains a constant pressure. In the present embodiment, the function of the spaced space unit 30 maintains a predetermined interval between the skin contact unit 10 and the pulse wave sensor 20, and the change of the magnetic field caused by the magnetic body of the skin contact unit 10. As it is to deliver to the pulse wave sensor 20. Therefore, any means can be used in the present invention as long as the predetermined separation interval can be maintained and the change in the magnetic field caused by the magnetic body of the skin contacting part 10 can be transmitted to the pulse wave sensor 20 as it is.

The separation distance of the positive pressure chamber (distance between the skin contact part and the pulse wave sensor part) is the magnetic field strength of the magnetic body of the skin contact part 10 and the magnetic sensitivity of the unit cell 22 of the pulse wave sensor part 20. Although determined according to the present invention, when the magnetic body of the skin contact portion 10 is a ribbon type magnetic pad having a magnetic field strength of 200 to 300 Oe, the separation distance is preferably maintained at 1 to 3 mm.

In addition, the part which is not described about the sensor part 110 of this embodiment is based on patent application No. 10-2005-0098677 (pulse sensor using a magnetic thin film) filed on October 19, 2005.

Next, any one of the wearing means 140, the sensor unit 110 and the data processing unit 120 in order to easily obtain a vein of the "part", "medium", "spit" state according to the traditional Chinese medicine pulse method It is preferable to further include a pressure control device (pressure control unit) to adjust the pressure applied to the skin contact portion 10 to the skin.

Here, the wearing means 140 is preferably a belt type such as a wrist strap or a ring (ring) type such as a ring for accurate operation control by the pressure regulating device (pressure adjusting unit) and ease of wearing. .

When the wearing means 140 is provided with a pressure regulating device (pressure adjusting part), a means for reducing the length of the belt or a radius of the ring (ring) (for example, a gear type adjusting device operating by receiving a pressure signal) is provided. It can be easily implemented through.

In addition, when the sensor unit 110 is provided with a pressure regulating device (pressure adjusting unit) can be implemented by employing a means for adjusting the air pressure in the space space portion 30 of the sensor portion (for example, the static pressure chamber).

When the data processor 120 is provided with a pressure regulating device (pressure regulating part), the skin contact part is realized by applying a pressure signal transmitted using a haptic device, which will be described later, to the applied pressure. (10) can be applied.

On the other hand, the data processing unit 120, as shown in Figure 7, the signal processing unit 122 for processing the pulse wave signal measured by the sensor unit 110; A storage unit 124 for storing the pulse wave signal data processed by the signal processor; A signal transmitter / receiver 128 for transmitting or outputting the pulse wave signal data processed by the signal processor or pulse wave signal data stored in the storage unit to the outside and receiving an external signal; It may be configured to include a control unit 125 for controlling each functional block embedded in the data processing unit.

Here, the data processor 120 may further include a screen display unit 129 for displaying a diagnosis result by the control state of the controller 125 or the pulse wave signal data stored in the storage unit 124.

Finally, the signal processor 122 of the data processor includes a signal including at least one of a differential circuit, a noise filter, a signal amplifier, and an output attenuator for detecting an amount of change of the pulse wave signal measured by the sensor unit 110. It is preferable to include a variation detection circuit.

Since the technology related to each component of the data processor 120 according to the present embodiment is already known, a detailed description thereof will be omitted.

[Wearing type On the pulse  2nd on Example ]

In the first embodiment of the wearable pulsator, only the hall element is substituted for the magnetic element such as the GMR element or the MTJ element among the components of the sensor unit 110.

Therefore, a key feature of the present embodiment is the skin contact part 10 formed of the magnetic body of the sensor unit 110, the pulse wave sensor unit 20 formed of an array of hall elements, and a predetermined space therebetween. It consists of a spaced apart space portion 30 to form a magnetic field of the skin contact portion 10 receives the pulsation caused by the radial artery to change the magnetic field (magnetic field) applied to the hall (hall) and the hall (hall) By allowing the device to detect this change in the magnetic field, it is inversely accurate in detecting the pulsation of the radial artery.

To this end, the following matters should also be considered in this embodiment.

Since the configuration of the skin contact portion 10 and the spaced apart space portion 30 of the sensor unit 110 according to the present embodiment is the same as the first embodiment of the wearable pulsator, repeated description thereof will be omitted.

Two sensing terminals (current input and output terminals) and two measuring terminals (hall voltage measuring terminals) are required.

The Hall voltage V _H measured by the Hall element is represented by Equation 1 below (see Korean Patent Publication No. 10-2004-64263).

[Equation 1]

V _H = (Grr _H I B _z ) / (n e t)

Where G is a geometric factor related to Hall element size, r _H Is the hole scattering factor, I is the sensing current, B _z The intensity of the applied magnetic field, n is the carrier concentration, e is the unit charge, and t is the thickness of the layer through which the sensing current flows in the Hall element.

According to Equation 1, the strength B _z of the magnetic field under the same conditions Since the Hall voltage V _H varies depending on the degree of variation, the variation of the strength B _z of the magnetic field can be known by measuring the Hall voltage V _H , through which the magnetic body of the skin contact 10 moves and thus the vibration of the Mac. It can be used in this embodiment that can be grasped.

Therefore, in the present embodiment, as in the first embodiment of the wearable pulsator, it is preferable to package the pulse wave detection sensor unit 20 in various array forms using the hall element as the unit cell 22.

The pulse wave detection sensor unit 20 may include a data processing unit 120 at one side or a spaced apart position, and may include a voltage variation detection circuit of the hall voltage measured from each Hall element. It is preferable to include a differential circuit for catching only fluctuations in the Hall voltage measured from each Hall element, that is, a change in the magnetic field, and further, a noise filter, signal amplification means, and output attenuation means for removing noise due to movement during measurement.
