Description

Smart healthcare mattress control device {APPARATUS FOR CONTROLLING SMART HEALTH CARE MATTRESS}

The present invention relates to a smart healthcare mattress control device, and more particularly, to a smart healthcare mattress control device for a healthy and comfortable sleep.

In general, a biosignal such as a respiration rate is one of the most convenient factors for diagnosing the health condition of the human body and the presence/absence of abnormality. Bio-signals are continuously checked by attaching a bio-signal measuring device (eg, respirator) to critically ill patients, emergency patients, patients during surgery, or the elderly who are vulnerable to health maintenance.

For example, an oxygen mask is attached to a patient during surgery to continuously check the patient's breathing status during surgery. Due to this, it restricts the movement of people such as doctors, and it is difficult to combine with other procedures or surgeries.

In addition, in many cases, it is necessary to check the respiratory status of people who live outside the hospital as well as patients who are hospitalized or operated in a hospital. For example, it is necessary to measure the breathing pattern of the elderly who have unstable breathing patterns or the breathing patterns of infants and young children living in a different space from their parents or breathing patterns during sleep.

In particular, in recent years, it is necessary to go beyond diagnosing sleep apnea, which is a disease that temporarily stops breathing during sleep, and to measure the actual respiration rate or respiration rate and use it to diagnose a person's health condition.

However, in the prior art, it was difficult to obtain data by accurately measuring the user's respiration rate and respiration volume without respiration measuring equipment such as those provided in the hospital, and to accurately deliver the acquired data to a doctor in the hospital.

In particular, the conventional method of measuring the respiration rate using a primary signal obtained from the sensor by attaching a simple sensor to the body is in a state that is much insufficient compared to the method of measuring the respiration rate through hospital equipment in its accuracy. .

In order to solve this problem, in Korean Patent Registration No. 10-1654914 (respiration measuring device and respiration measuring method using the same), a pad attachable to the user's body, and installed on the pad, Three or more sensors for measuring a signal generated according to the movement of the user's body, and a determination unit for measuring the user's respiration rate using the signals measured by at least two or more of the three or more sensors, The sensor includes a first sensor and a second sensor, and the determination unit compares the first signal measured by the first sensor with the second signal measured by the second sensor, and within a time difference within a preset range. By counting the number of times the peak value of the first signal and the second signal appears and counting the number of respirations, it discloses a respiration measurement device that can accurately and simply and accurately measure the user's respiration rate.

In this prior art, the user's respiration data in daily life outside the hospital can be transmitted to a system such as a hospital to remotely check the user's health status in real time, and the user's respiration rate without attaching equipment such as an oxygen mask to the user It has the advantage of being able to monitor the patient's respiration status in real time while concurrently with surgery and various treatments.

However, in the prior art respiration measurement device and respiration measurement method, as a contact-type device attached to the user's body, it has a limitation that the respiration cannot be measured unless the user wears it.

1 to 7, the smart healthcare mattress control device according to an embodiment of the present invention is largely a mattress 100, at least one healthcare sensor module (200-1 to 200-N), healthcare It consists of a control module 500, and a power supply module 600, and the like. In addition, the smart healthcare mattress control apparatus according to an embodiment of the present invention may further include a storage module 300 , a display module 400 , an external terminal 20 , and the like. On the other hand, since the components shown in FIGS. 1 to 7 are not essential, the smart healthcare mattress control device according to an embodiment of the present invention may have more components or fewer components than that.

Hereinafter, the components of the smart healthcare mattress control device according to an embodiment of the present invention will be described in detail as follows.

The mattress 100 is usually a rectangular flat mat made by laminating at least one cushion member (eg, a spring, a sponge, a thermal insulation material, etc.) on the inside of the outer shell, and is mainly used by laying on the frame of the bed. Preferably, but not limited thereto, for example, it may be made in the form of a mattress topper (Matress Topper) used by laying on the floor or the main mattress.

Each healthcare sensor module (200-1 to 200-N) is mounted in a predetermined space (A) formed in the cushion member of the mattress 100, and is electrically connected to the healthcare control module 500, A function of non-contact detection of a signal related to biometric information of a measurement target (eg, a patient, a general public, etc.) existing on the mattress 100 using a radar sensor according to the control of the healthcare control module 500 carry out

In this case, the radar sensor is a sensor that transmits electromagnetic waves in a specific direction, and may include, for example, a milli-millimeter wave radar sensor (mmWave Radar Sensor). The millimeter wave radar sensor is a sensor using a frequency between 60 GHz and 70 GHz.

The frequency between 60 GHz and 70 GHz has a directivity capable of concentrating the electromagnetic wave in a specific direction, and since the electromagnetic wave composed of a frequency having such a directivity characteristic is not affected by other external operations, biometric detection of multiple human bodies is not possible. It may be possible.

For example, if the electromagnetic wave output from the millimeter wave radar sensor is compared with the reflected electromagnetic wave data (RSS value) reflected by the person and the object, the object and the person have different amounts of reflection depending on the dielectric constant of the object and the person. It is possible to observe the reflection of the amount of electromagnetic waves, and through regression analysis of the reflected electromagnetic waves versus the output electromagnetic waves, it is possible to distinguish whether the object that reflects the electromagnetic waves is an object or a person.

On the other hand, the radar sensor may use IR-UWB (Impulse-Radio Ultra WideBand) technology for irradiating an ultra-wideband (UWB) impulse signal in a short distance and measuring a reflected radio signal.

This IR-UWB technology has recently been introduced as a high-accuracy position estimation technology because IR-UWB uses a very narrow impulse ranging from several ns to several hundreds of ps, making it more efficient than narrowband signals. This is because it has strong characteristics against multipath.

In addition, the IR-UWB method is a technology that uses a frequency band of several GHz or more in a baseband without using a radio carrier, and is a new radio technology applied to communication or radar. The IR-UWB technology uses very narrow pulses of several nanoseconds or several picoseconds, so it can be implemented with low power and has the advantage that it can be used in conjunction with a conventional communication system.

In addition, each healthcare sensor module 200-1 to 200-N, as shown in FIGS. 2 and 3, is largely a radar transmitter 210, a radar receiver 220, a signal processor 230, and a PCB board. It consists of a unit 240, and a PCB protection unit 250, and the like.

Here, the radar transmitter 210 performs a function of transmitting a first signal having a radar pulse with respect to a corresponding measurement target existing on the mattress 100 .

That is, the radar transmitter 210 transmits a first signal having a radar pulse with respect to the corresponding measurement target existing on the mattress 100, and radiates an impulse signal for sensing the corresponding measurement target to the outside. (Radiation), although not shown in the drawing, may typically include an impulse generator, a transmit antenna, and a transmit controller.

Here, the impulse generator may generate an impulse based on data for impulse generation provided from the transmission control unit. For reference, in ultra-wideband (UWB) radar, the shorter the pulse period, the more information it can contain. If the contrast bandwidth exceeds about 20%, it is included in the ultra-wideband (UWB) radar, and the impulse generator can generate an impulse that meets this definition.

The transmitting antenna may radiate the pulse signal generated by the impulse generator to the outside, and in this case, the pulse signal may be generated in a preset area. For reference, the transmitting antenna is preferably an ultra-wideband antenna having high directivity.

The transmission control unit may provide data for generating an impulse to the impulse generator, and the impulse generator may generate an impulse under the control of the transmission control unit.

The radar receiver 220 performs a function of receiving a second signal reflected from a corresponding measurement target and related to the first signal.

Although not shown in the drawing, the radar receiver 220 may include a receive antenna, a receive controller, and the like.

Here, the receiving antenna may receive the reflected signal of the pulse radiated by the radar transmitter 210, and an ultra-wideband antenna having high directivity may be used.

The reception control unit may analyze a signal received by the reception antenna. The signal received through the receiving antenna includes not only the reflected signal of the measurement target, which is the detection target, but also the reflected signal from a nearby object, and signals other than the object must be removed for accurate measurement of the measurement target.

In addition, the reception control unit may include conventional components, for example, an amplifier, an A/D conversion unit, a D/A conversion unit, a sampling unit, a demodulator, a filter unit, and the like, and these components are a typical radar unit. and, a detailed description thereof will be omitted.

The signal processing unit 230 extracts a frequency based on the first and second signals transmitted and received from the radar transmitter 210 and the radar receiver 220, and a signal related to the biometric information of the corresponding measurement target according to the phase difference of the frequency functions to process

That is, the signal processing unit 230 may extract a frequency from the reflected electromagnetic wave data and pre-process the phase of the extracted frequency. Here, the data of the reflected electromagnetic wave may include a frequency domain including movement information on a person's respiration or heartbeat. A dominant frequency peak is generated at a frequency extracted from the reflected electromagnetic wave data, and the frequency of the frequency peak may be related to a person's respiration rate or heart rate.

The signal processing unit 230 converts the reflected electromagnetic wave data into the frequency domain through Fast Fourier Transform (FFT), and converts the peak value of the frequency in the frequency domain corresponding to a preset frequency range among the converted frequency domains. detected, and the phase value of the frequency according to time may be measured using the peak value of the detected frequency.

Specifically, when the transmitted electromagnetic wave is reflected back, the signal processing unit 230 collects and collects data about a plurality of reflected electromagnetic waves (eg, a reflected electromagnetic wave that has been directly reflected, a reflected electromagnetic wave reflected N times, etc.) Only data of the same frequency band among the plurality of reflected electromagnetic waves can be acquired.

Then, the signal processing unit 230 converts the acquired data of a plurality of reflected frequencies in the same frequency band into a frequency domain through fast Fourier transform (FFT), and extracts frequencies related to respiration rate and heart rate from among the converted frequency domains. can do.

Also, the signal processing unit 230 may convert the converted frequency domain into a time domain to detect a peak value, measure a distance between the detected peak values, and calculate a correlation coefficient with respect to a human heartbeat.

Also, the signal processing unit 230 may process phase unwrapping with respect to the extracted frequency. For example, since the phase values are between [-π, π], the signal processing unit 230 may process phase unwrapping by adding or subtracting 2π from the phase when the phase difference between successive values is greater or smaller than ㅁπ. have.

Also, the signal processing unit 230 may process a phase difference in which a continuous phase value is subtracted from a phase subjected to phase unwrapping. Through the processing of the phase difference, it is possible to improve the accuracy of the human heartbeat data, and it can help to remove the phase deviation.

In addition, the signal processing unit 230 may determine a person's respiration rate and heart rate by performing spectrum estimation on the frequency at which the phase unwrapping and phase difference have been processed.

That is, the signal processing unit 230 generates a correlation expression of the respiration rate with respect to the frequency peak using the frequency related to the extracted respiration rate, and a preset respiration rate frequency region (eg, 0.5 at 0.1 Hz) in the frequency related to the extracted respiration rate. The respiration rate of a person may be determined based on the data of the frequency included in Hz.

In addition, the signal processing unit 230 generates a correlation expression of the heart rate with respect to the frequency peak by using the extracted heart rate-related frequency, and in a preset heart rate frequency range (eg, between 0.8 Hz and 4.0 Hz) from the extracted heart rate-related frequency. Based on the included frequency data, it is possible to determine a person's heart rate.

The PCB board unit 240 is equipped with electronic circuit elements required for the radar sensor, including the radar transmitter 210, the radar receiver 220, and the signal processor 230, on a predetermined printed circuit board (PCB), as well as the health A data cable (C) for sensor communication and power supply with the care control module 500 is electrically connected.

The PCB protection unit 250 is molded so that the entire outside of the PCB substrate unit 240 is covered by injection molding of liquid silicone in order to waterproof and prevent shock of the PCB substrate unit 240 .

And, the health care control module 500 performs overall control of the smart health care mattress control device according to an embodiment of the present invention, in particular, detected from each health care sensor module (200-1 to 200-N) It receives a signal related to the biometric information of the measurement target and performs a function of analyzing at least one health care status information among the respiration, heartbeat, movement, distance, sleep, and/or condition status of the measurement target based on the received signal.

In addition, the healthcare control module 500 converts the healthcare status information analyzed for each healthcare status into a database (DB) to store and manage it in the storage module 300, and displays it so that the user can visually check it. A function of controlling the operation of the display module 400 to be displayed on the screen may be performed.

At this time, respiration (normal/high/low), heart rate (normal/high/low), movement (normal/active/small), distance (normal/active/small), sleep (normal/excessive/sleep) of the measurement target Insufficient), and/or analysis of health care status information such as condition (stable/unstable) state may be performed through a typical pattern analysis.

In addition, the healthcare control module 500 applied to an embodiment of the present invention includes a communication unit 505 , a radon measurement unit 506 , a fine dust detection unit 507 , an ultrafine dust detection unit 508 , and a temperature measurement unit. 509 , a humidity measuring unit 510 , a carbon monoxide sensing unit 511 , and/or a carbon dioxide sensing unit 512 may be further included.

When it is determined to be greater than or equal to the reference approximation value, the smallest converted sensor measurement value is output, that is, the healthcare sensor module having the smallest difference among the final measurement values of the corresponding healthcare sensor modules 200-1 to 200-N. A function of outputting the final measured value of (200-1 to 200-N) and analyzing the health care status information of at least one of respiration, heartbeat, movement, distance, sleep, and/or condition of the measurement target based on this can be performed.

The radon measuring unit 506 is a sensor unit for measuring radon concentration data around the mattress 100, for example, preferably made of an ionization chamber type radon measuring sensor, but is not limited thereto. For example, alpha As a device for detecting particles, a surface barrier type, a high-purity semiconductor detector (pure Ge), a scintillation (scintillation) detector, a solid state junction counter, etc. may be applied.

That is, the pulsed ionization chamber type radon measuring sensor has a structure in which an electric field is formed by installing a probe-shaped electrode in the center of a metal cylindrical box and applying a bias voltage between the metal cylinder and the inner probe.

When alpha decay occurs inside the ionization chamber and alpha particles are released, the alpha particles disappear due to collision with air, but ionic charges are generated. The sensor itself is composed of a metal cylinder and a probe, so it is very inexpensive, durable, and has the advantage of good ventilation because it is independent of light.

Looking at the surface barrier detector, a depletion layer such as a p-n junction is formed on the surface of the semiconductor due to a surface level or an oxide film, and thus, the vicinity of the surface becomes an obstacle for charge transfer. As a practical matter, gold is deposited on the surface of the n-type si by about 100 µm/cm 2 , and this is used as one electrode and radiation is incident on the back surface. Here, the thickness of the depletion layer is about 50 to 500 μm, and since it has a small energy loss at the surface, it is mainly used for detection of charged particles generated by alpha radiation and has good energy resolution.

The high-purity semiconductor detector is generally referred to as a pure Ge detector. It is a high-purity Ge crystal with very little impurity concentration or defects. It has very high electrical resistance at low temperatures and can apply a high bias voltage. The difference from Ge(Li) is that it can be stored at room temperature and only needs to be cooled with liquid nitrogen for measurement, so it is convenient to maintain and the energy resolution is not inferior to that of Ge(Li), so it is being put to practical use.

Looking at the scintillation detector, the phenomenon of emitting light when charged particles collide with a substance has been known for a long time, but the luminescence by alpha radiation of zinc emulsion (ZnS) or NaI coating film is particularly strong, and detection and counting are possible with a magnifying glass in a dark room.

Such light emission is called scintillation (scintillation), and a material exhibiting this phenomenon is called a scintillator. In addition, a scintillator coupled with a photomultiplier tube is called a scintillation detector, but in particular, a method used for counting as a pulse output is called a scintillation counter.

On the other hand, the method that reads the output in direct current is mainly used for dosimetry and is called a scintillation dosimeter because it uses a scintillator. say

The solid junction counter is a solid reverse bias p-n junction semiconductor, and is a counter designed to collect ionic charges from alpha particles passing through a depletion layer, and can be manufactured in a compact, mobile type.

The temperature measuring unit 509 is a sensor unit for measuring a temperature in the air, and a thermistor element whose internal resistance value changes according to a change in ambient temperature may be used. The thermistor element may be a negative characteristic thermistor (NTC thermister), a positive characteristic thermistor (PTC thermistor), or a critical characteristic thermistor (CRT).

The humidity measuring unit 510 can be largely divided into a resistive humidity sensor and a capacitive humidity sensor, and is used to optimize not only home appliances and mobile devices, but also automobiles and medical devices, air purification systems, and automatic heating and cooling systems. It is widely applied.

The resistance-type humidity sensor measures humidity by using a change in resistance that is changed by humidity. This resistance-type humidity sensor has been widely used because it has a relatively competitive price compared to the capacitive-type humidity sensor.

However, in recent years, as the capacitive humidity sensor can be manufactured in the form of a one-chip on a semiconductor substrate, it is possible to secure a price competitive advantage compared to the resistance-type humidity sensor, so the use is increasing. In particular, the capacitive humidity sensor has advantages in that the sensor characteristics are linear and the effect of temperature is small, while having superior reliability compared to the resistance type humidity sensor.

Such a capacitive humidity sensor is a sensor using the principle that the capacitance changes according to the molecular weight of water adsorbed to the moisture-sensitive film, and uses a moisture-sensitive material, such as polyimide or ceramic, whose dielectric constant changes when moisture is absorbed. It operates in the form of a capacitor made of a dielectric. That is, it is a principle of detecting that a moisture-sensitive layer for sensing humidity exists, and when moisture flows through the moisture-sensitive layer, the dielectric constant changes and the capacitance changes accordingly.
