Description

Smart hospital bed monitoring system capable of patient identification {APPARATUS FOR CONTROLLING SMART HEALTH CARE MATTRESS}

The present invention relates to a smart hospital bed monitoring system capable of patient identification.

Generally, in the case of patients admitted to hospitals, most patients receive treatment in a hospital bed or receive treatment while resting during their hospitalization. Additionally, even when admitted to a nursing facility, a significant amount of time is spent in bed receiving treatment.

However, there are no devices to support or monitor patient convenience in hospital beds, and even if such devices exist, they are only partially supported, the overall structure is complicated, and the overall system is expensive, so it is not used except in special hospital rooms. Most of them are.

In addition, many new highly infectious infectious diseases, such as MERS and coronavirus, have become prevalent recently. In these cases, it is common for suspected patients or medical personnel who have been in contact with patients to be quarantined, even if they are not patients.

Therefore, in the case of highly infectious patients, there is a need to avoid unnecessary contact with the patient and continuously check the patient's condition for treatment.

To solve the above problems and needs, several technologies for patient monitoring have been disclosed. Domestic Patent No. 10-2139047, registered by the same applicant, discloses technology related to a smart healthcare mattress.

It is about a smart healthcare mattress that is being transmitted.

However, since the above prior art detects all biometric signals within the radar range at all times, there is a problem of detecting the biometric information of the patient and others at the same time, or detecting the biometric information of others when the patient is absent, so that the patient lives with others such as guardians. In shared hospital rooms, it is difficult to collect pure biosignal data from patients.

It may be possible.

Hereinafter, we will look in detail at the components of a smart hospital bed monitoring system capable of patient identification according to an embodiment of the present invention.

The hospital bed 100 is provided so that the patient 1 can lie down. As shown in FIG. 2, the bed frame 110 largely supports the bed, and the bed mattress installed on the bed frame 110. It consists of (120) and fall prevention side rails (130) installed on both sides of the bed frame (110) to prevent the patient (1) from falling.

The RFID tag 150 is provided in the form of, for example, a necklace, bracelet, or anklet so that the patient 1 can carry it, and performs the function of storing preset unique tag identification information.

In addition, the RFID tag 150 preferably further stores preset unique patient identification information corresponding to the unique tag identification information.

At this time, the unique tag identification information includes, for example, the name of the electronic tag, the password of the electronic tag, the serial number of the electronic tag, the type of the electronic tag, the manufacturer of the electronic tag, the MAC (Media Access Control) address of the electronic tag, and the electronic tag's MAC (Media Access Control) address. It is desirable to include at least one of the tag's unique IP (Internet Protocol) address, the model and version of the electronic tag, and the electronic tag's authentication information generated by the electronic tag's secret key or PKI-based private key. It is not limited and may include all electronic tag identification information that can identify the RFID tag 150.

The unique patient identification information includes at least the patient's name, resident registration number, phone number, address, biometric characteristic information, PKI (Public Key Infrastructure), OTP (One Time Password), public certificate, or hospital patient registration number information. It is preferable to include one piece of information, but it is not limited to this and may include all patient identification information that can identify the patient 1.

A plurality of RFID readers (200-1 to 200-N) are mounted on one side (preferably front/back/left/right, etc.) of the hospital bed 100, and transmit information of the RFID tag 150 to RFID. (Radio Frequency Identification) and performs the function of transmitting unique tag identification information of the recognized RFID tag 150.

In addition, the plurality of RFID readers (200-1 to 200-N) may perform the function of transmitting unique tag identification information of the recognized RFID tag 150 as well as unique patient identification information corresponding thereto. .

The radar sensor device 250 is mounted on one side of the hospital bed 100 (preferably, the inside of the bed mattress 120, etc.), and uses at least one radar to detect the top of the hospital bed 100. It performs the function of non-contactly detecting signals related to the biometric information of the patient (1) present in.

This radar sensor device 250 uses a radar sensor under the control of the radar control device 300 to non-contactly detect signals related to the biometric information of the patient 1 present on the hospital bed 100. As such, the radar sensor is a sensor that transmits electromagnetic waves in a specific direction and may include, for example, a mmWave radar sensor. Millimeter-wave radar sensors are sensors that use frequencies between 60GHz and 70GHz.

The frequency between 60 GHz and 70 GHz has a directivity that can concentrate electromagnetic waves in a specific direction, and since electromagnetic waves composed of frequencies with such directivity characteristics are not affected by other external operations, biological detection of multiple human bodies is possible. It may be possible.

For example, when comparing the data (RSS value) of the electromagnetic waves output from a mmWave radar sensor and reflected electromagnetic waves reflected by people and objects, the objects and people reflect different amounts depending on the dielectric constants of each object and person. The amount of electromagnetic waves reflected can be observed, and through regression analysis of the reflected electromagnetic waves compared to the output electromagnetic waves, it is possible to distinguish whether the object reflecting the electromagnetic waves is an object or a person.

Meanwhile, the radar sensor may use IR-UWB (Impulse-Radio Ultra WideBand) technology, which irradiates ultra-wideband (UWB) impulse signals at a short distance and measures reflected wireless signals.

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

In addition, the IR-UWB method is a technology that uses a frequency band of several GHz or more in the baseband without using a wireless carrier, and is a new wireless technology applied to communications, radar, etc. IR-UWB technology has the advantage of being able to be implemented with low power by using very narrow pulses of a few nanoseconds or several picoseconds and being able to be used in conjunction with conventional communication systems.

In addition, although not shown in the drawing, the radar sensor device 250 may largely include a radar transmitter, a radar receiver, a signal processor, a PCB substrate, and/or a PCB protection unit.

Here, the radar transmitter performs a function of transmitting a first signal having a radar pulse to the patient 1 present on the hospital bed 100.

That is, the radar transmitter transmits a first signal with a radar pulse to the patient 1 present on the hospital bed 100, and sends an impulse signal for detection of the patient 1 to an external It is a component that radiates, and although not shown in the drawing, it 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, the shorter the pulse period in an ultra-wideband (UWB) radar, the more information it can contain. According to the FCC's definition, a pulse signal with a pulse width of only a few ns is generated, and the bandwidth exceeds 500 MHz or the center frequency is If the contrast bandwidth exceeds about 20%, it is included in ultra-wideband (UWB) radar, and the impulse generator can generate impulses that meet this definition.

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

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

The radar receiver is reflected from the patient 1 and performs a function of receiving a second signal related to the first signal.

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

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

The reception control unit may analyze the signal received by the reception antenna. The signal received through the receiving antenna includes not only a reflected signal from the patient 1, which is the detection target, but also a reflected signal from surrounding objects. In order to accurately measure the patient 1, signals other than the object must be removed.

In addition, the reception control unit may include typical components such as an amplification unit, an A/D conversion unit, a D/A conversion unit, a sampling unit, a demodulation unit, a filter unit, etc., and these components may be used in conjunction with a conventional radar Since it is the same as , detailed description thereof will be omitted.

The signal processing unit extracts a frequency based on the first and second signals transmitted and received from the radar transmitting unit and the radar receiving unit, and has a function of processing signals related to the biometric information of the patient 1 according to the phase difference of the frequencies. Perform.

That is, the signal processing unit can extract a frequency from data of reflected electromagnetic waves and preprocess the phase of the extracted frequency. Here, the data of the reflected electromagnetic waves may include a frequency domain containing movement information about the patient's (1) breathing or heart rate. A dominant frequency peak occurs in the frequency extracted from the reflected electromagnetic wave data, and the frequency of the corresponding frequency peak may be related to the breathing rate or heart rate of the patient 1.

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

Specifically, when the transmitted electromagnetic wave is reflected and returned, the signal processing unit collects data on the plurality of reflected electromagnetic waves (e.g., directly received reflected electromagnetic waves, reflected electromagnetic waves reflected N times, etc.), and collects the collected plurality of electromagnetic waves. Of the reflected electromagnetic waves, only data in the same frequency band can be acquired.

In addition, the signal processing unit converts the acquired data of a plurality of reflection frequencies in the same frequency band into a frequency domain through Fast Fourier Transform (FFT), and extracts frequencies related to breathing rate and heart rate from the converted frequency domain. there is.

In addition, the signal processing unit can convert the converted frequency domain into the time domain, detect a peak value, and measure the distance between the detected peak values to calculate a correlation coefficient related to the heartbeat of the patient 1.

Additionally, the signal processing unit may process phase unwrapping of the extracted frequency. For example, the signal processing unit may process phase unwrapping by adding or subtracting 2π from the phase when the phase difference between consecutive values is greater or less than ±π because the phase value is between [-π, π].

Additionally, the signal processing unit can process phase difference, which subtracts continuous phase values from the phase for which phase unwrapping has been processed. Processing this phase difference can improve the accuracy of human heart rate data and help eliminate phase deviation.

This radon measuring device 500 is a sensor unit for measuring radon concentration data about the surroundings of the hospital bed 100, and is preferably made of, for example, an ionization chamber type radon measuring sensor, but is not limited to this, for example. , Surface barrier type, high-purity semiconductor detector (pure Ge), scintillation detector, solid state junction counter, etc. may be applied as devices for detecting alpha particles.

That is, the pulsed ionization chamber type radon measurement sensor is structured by installing a probe-shaped electrode in the center of a metal cylindrical box and forming an electric field by applying a bias voltage between the metal cylinder and the internal probe.

When alpha decay occurs inside the ionization chamber and alpha particles are released, the alpha particles are destroyed by collision with air, but ion charges are generated, so the alpha particles can be detected by absorbing them through the central probe and amplifying the signal. The sensor itself is composed of a metal cylinder and a probe, so it is very inexpensive, durable, and independent of light, so it has the advantage of improving breathability.

Looking at the surface barrier type detector, the surface of the semiconductor has a depletion layer such as a p-n junction formed due to the surface level or oxide film, so the area near the surface becomes an obstacle to charge movement. In practical terms, gold is deposited at a thickness of about 100㎛/cm2 on the surface of n-type Si, this is used as one electrode, and radiation is incident on the back side. Here, the thickness of the depletion layer varies from about 50 to 500㎛, and because the energy loss at the surface is small, it is mainly used to detect charged particles generated by alpha radiation and has good energy resolution.

The high-purity semiconductor detector is also commonly called a pure Ge detector. It is a high-purity Ge crystal with very small impurity concentration or defects, 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, making it easy to maintain, and its energy resolution is comparable to that of Ge(Li), so it is being put into practical use.

Looking at the scintillation detector, the phenomenon of a charged particle emitting light when it hits a material has been known for a long time, but the luminescence caused by alpha radiation from zinc emulsified (ZnS) or NaI coating films is particularly strong and can be detected and counted with a magnifying glass in a dark room.

This kind of light emission is called scintillation, and the material that exhibits this phenomenon is called a scintillator. And, a scintillator combined with a photomultiplier tube is called a scintillation detector, but the method used for counting, especially as a pulse output, is called a scintillation counter.

On the other hand, the method of reading the output in direct current is mainly used for dosimetry. Since it uses a scintillator, it is called a scintillation dosimeter. Any of solid, liquid, or gas is used for the scintillator. If liquid is used, a liquid scintillation counting device is used. It is said that

The solid junction counter is a solid reverse bias p-n junction semiconductor that collects ion charges from alpha particles passing through a depletion layer and can be manufactured in a small and portable form.

This humidity measuring device 700 is a device for measuring humidity in the air, and usually measures humidity using changes in the electrical properties of a moisture-sensitive material due to moisture.

In other words, the humidity measuring device 700 can be largely divided into a resistance-type humidity sensor and a capacitance-type humidity sensor, and is used to optimize not only home appliances and mobile devices, but also automobiles, medical devices, air purification systems, and automatic cooling and heating systems. It is widely applied for this purpose.

The resistance-type humidity sensor measures humidity using changes in resistance that change due to humidity. This resistance-type humidity sensor was widely used because it was relatively price competitive compared to the capacitive humidity sensor.

However, recently, as capacitive humidity sensors have become possible to be manufactured in the form of one chip on a semiconductor substrate, their use is increasing as they can secure a price competitive advantage over the resistance-type humidity sensors. In particular, capacitive humidity sensors have the advantage of having superior reliability compared to resistance-type humidity sensors, while having linear sensor characteristics and less influence of temperature.

This type of capacitive humidity sensor is a sensor that uses the principle that capacitance changes depending on the molecular weight of water adsorbed on the moisture-sensitive film. It uses moisture-sensitive materials such as polyimide or ceramic, whose dielectric constant changes when moisture is absorbed. It operates in the form of a capacitor made of dielectric. In other words, the principle is that there is a moisture-sensitive layer that senses humidity, and as moisture flows through this moisture-sensitive layer, the dielectric constant changes and the capacitance changes accordingly.
