JP4786308B2 - A monitoring system that monitors the condition of the subject - Google Patents

Description

The present invention relates to the state of a subject based on biological data such as heart rate, respiratory rate, magnitude of body movement, body temperature, etc. in bedtime, lying down, supine etc. of a subject such as an elderly person, a patient being treated, an infant, etc. And a monitoring system for monitoring temperature information of the ice pillow.

In recent years, the population of elderly people tends to increase, and it is changing to a so-called aging society. For this reason, the burden of care for the elderly increases, especially in the case of home care, and it is necessary to always pay attention, and there is an immeasurable amount of effort when the family cares at night. As a result, an excessive burden is imposed on the caregiver, which is a big social problem.

Also, in hospitals and nursing homes, nurses and nurses are not always accompanied by patients or caregivers (subjects) during bedtime, lying down, or lying on their backs. Currently, we are dealing with this by reporting the health status of patients.

In recent years, even if elderly people have a sudden fever such as influenza in nursing homes, the information may be delayed and become serious. Also, as the nuclear family progresses and infants and others develop fever, it is necessary for one mother to take care of the patient overnight, and to change body temperature and replace the ice pillow each time. Even if an infant has a sudden fever such as influenza at home, the information may be delayed and become serious.

Under such circumstances, as a method of non-invasively, ie, unconstrained and continuously grasping the health status of the cared person without giving physical and mental burden to the cared person, the cared person (subject) A technique has been proposed in which an air mat is laid under the body of the subject and the subject's heart rate, respiration rate, number of snoring times, number of times of turning, etc. are measured based on a pressure change applied to the air mat (Patent Document 1). In addition, a home dock system that checks information such as blood pressure, pulse, and body temperature every day while staying at home and displays a trend is also proposed (Patent Document 2).

However, it is necessary to manually input and transmit data such as blood pressure, pulse, body temperature and the like each time measurement is performed. However, a system for monitoring body temperature data of a living body without giving a physical and mental burden to a subject (an elderly person, a patient being treated, an infant) or a caregiver has not yet been proposed.

FIG. 1 shows an embodiment of the present invention, and shows a system including an air mat, an ice pillow, a subject P (infant), and a portable terminal installed at home or the like. The subject P is also the same in hospitals, nursing homes, nursing homes and the like. 2 is a block diagram of a terminal device, FIG. 3 is a block diagram of an IC tag (RFID) having a temperature measurement unit, FIG. 4 is a flowchart showing a biological information / temperature acquisition information processing flow, and FIG. 5 is a display unit. 2 is a trend graph of body temperature / temperature displayed on the screen. FIG. 6 is a plan view showing details of the ice pillow.

In FIG. 1, in a room such as a hospital, a care facility, or a home, a subject P installs a dedicated air mat 2 for measuring biological data on a bed or floor, and the subject (infant) P places an ice pillow 120 on the head. It is in a state of lying on its back. A terminal device (not shown) having a function of a personal computer or the like is connected to the data measurement dedicated air mat 2 via the air tube 4 so that the pressure change of the data measurement dedicated air mat 2 can be transmitted to the terminal device.

<Specific configuration of monitoring system>
The subject P wears a diaper (pants) 200 on the air mat 2 for measuring biological data. The diaper 200 includes a trunk opening 201 provided with an elastic member, a leg opening 202 provided with an elastic member, and an absorbing member (not shown), and the IC tag 100 having a temperature measuring unit is separated from the absorbing member inside. Prepare for the right place. The diaper 200 is not limited to a pants shape, but may have other shapes. Alternatively, the diaper may be made of cloth, made reusable and a diaper cover may be used, and the diaper may be provided at an appropriate place inside that is not wet by urine. The IC tag 100a having the temperature measuring unit may be surrounded by an enclosing member having a hook-and-loop fastener and the like so as to be detachable. An IC tag 100b having a temperature measuring unit is provided on the outer surface of the ice pillow 120.

The terminal device 5 includes a pressure sensor that detects a change in pressure, and processes the detection signal to a management site / medical site (not shown) via a dedicated line such as a LAN or an information communication network such as the Internet (not shown). A control monitoring device for transmission is provided.

Note that the IC tag 100a having the temperature measuring unit may be inserted into the ear, or may be attached to an arbitrary location on the body surface to acquire body temperature information at a plurality of locations. In this case, an anti-coregion type IC tag is used, which enables reading of body temperature information at the same time.

A server (data processing device) may be installed at the management site / medical site, and the measurement data of biological data may be collected, aggregated, analyzed, etc. in association with the ID of the subject P.

In FIG. 2, reference numeral 40 denotes a control unit (CPU) that executes a predetermined processing flow based on a computer-readable program stored in the ROM 42, the RAM 43, etc., predetermined conditions, and the like. Reference numeral 36 denotes a display unit, and 44 denotes a storage unit that stores biological data such as detected body temperature, heartbeat, and respiration. Reference numeral 20 denotes a fine differential pressure sensor, and reference numeral 21 denotes an absolute pressure sensor. The internal pressure of the air mat 2 is input to the fine differential pressure sensor 20 and the absolute pressure sensor 21 via the air tube 4. Since vibration due to the body of the subject P is transmitted to the air mat 2, the internal pressure of the air mat 2 changes. The fine differential pressure sensor 20 detects the pressure fluctuation, and the absolute pressure sensor 21 detects the absolute pressure of the internal pressure of the air mat 2. The absolute pressure sensor 21 is provided to detect whether the subject P is on the air mat 2.

As the fine differential pressure sensor 20, for example, a condenser microphone type differential pressure gauge that detects a differential pressure by detecting a change in capacitance between a pressure-receiving surface that receives a change in pressure and a counter electrode is used. The condenser microphone type differential pressure gauge can detect minute pressure fluctuations in the air mat 2.

The detection signal of the fine differential pressure sensor 20 is given to a gain control unit 31 that constitutes the monitoring control device 30. The gain control unit 31 adjusts the level of the detection signal of the fine differential pressure sensor 20 to a signal level within a predetermined range. Since the strength of vibration such as heartbeat and respiration transmitted to the air mat 2 varies depending on the posture of the subject P, the intensity (level) of the output signal of the fine differential pressure sensor 20 varies. The gain control unit 31 adjusts the gain so that a signal level that varies depending on the posture becomes a signal of a predetermined level, and outputs the signal to the heartbeat filter 32 and the respiratory filter 33. Further, the gain value of the gain control unit 31 is added to the posture determination unit 36. By applying the output signal of the differential pressure sensor 20 converted to a predetermined level by the gain control unit 31 to the heartbeat filter 32 and the respiratory filter 33, the heartbeat signal and the respiratory signal are detected from the heartbeat filter 32 and the respiratory filter 33. The biological data of the person P is obtained. The biological data of the subject P obtained from the heartbeat filter 32 and the breathing filter 33 is converted into a digital signal by the A / D conversion unit 35 and input to the data processing unit 37. Further, temperature information is intermittently received by the IC tag reading unit 34 (for example, every 5 to 30 minutes) from the IC tag 100a with a temperature sensor (see FIG. 1) attached to the inside of the diaper 200 attached to the subject P. Read on. The IC tag reader 34 transmits an electromagnetic wave of 13.56 MHz, and the signal is received by the IC tags 100a and 100b with the temperature sensor via the antenna, and the temperature (body temperature) information by the temperature sensor 106 (in this embodiment, the test subject) Body temperature information near the abdomen of the person P) is read from the IC tags 100a, 100b with temperature sensors. The IC tags 100a and 100b can identify and read temperature information at the same time by using an anti-collusion type. The data processing unit 37 performs various arithmetic processes on the input biological data and monitors the state of the subject P. The various types of calculation processing of the biological data include pattern comparison with the normal biological data of the subject P. The data processing unit 37 performs arithmetic processing when the absolute pressure sensor 21 detects that the subject P is on the air mat 2.

Further, the gain value of the gain control unit 31 is added to the posture determination unit 36. Since the level of the detection signal of the fine differential pressure sensor 20 that detects the internal pressure of the air mat 2 differs depending on the posture of the subject P, the gain control unit 31 adjusts the gain.

<Structure of ice pillow>
The configuration of the ice pillow 120 will be described with reference to FIG. As shown in FIG. 6, the ice pillow 120 is composed of a main body 121, a grip portion 122, a clamp 123, and an outer surface of the main body 121 having a flexibility in a range of 0 to 40 ° C. made of latex, synthetic rubber, elastic synthetic resin or the like. The IC tag (RFID) 100 is provided on the inside, and ice and water are put in the inside thereof (FIG. 2A), or the ice pillow 120 is covered with a cover 125 and locked with a hook-and-loop fastener 124 or the like. (FIG. 2 (b)) type or an ice pillow 120 (FIG. 2 (c)) that is pre-filled with a freezing type refrigerant (freezing type cooling member: not shown) and has an IC tag 100, or this ice pillow 120. Is covered with a cover 125 and locked with a hook-and-loop fastener 124 or the like (FIG. 2D). There are two types of ice pillows, one that uses ice and cold water in a storage container made by Leix, and the other that stores frozen refrigerant in advance. In the case of a type in which the frozen refrigerant is stored in advance, the frozen refrigerant is a liquid or liquid at room temperature and a solution or liquid having a melting point in the range of −15 ° C. to 0 ° C. The latent heat of thawing at the time of thawing of the frozen refrigerant that has been frozen in the freezer is used for the cooling and storage function of the ice pillow. Although sensible heat of water and ice is also used for cold storage and cold storage, the difference between whether or not to use ice latent heat of melting (about 80 cal / g) is extremely large. Specific freeze-type refrigerants include, for example, a sol form in which a thickener such as plant polysaccharides, sodium carboxymethyl cellulose, synthetic sodium silicate / magnesium, sodium polyacrylate, water-absorbing resin, and the like are appropriately added to water. Or it is a gel-like transparent liquid. The frozen refrigerant of this embodiment is a transparent liquid. The supercooling release agent is mixed in a small amount with the freezing refrigerant in order to improve the supercooling phenomenon of the freezing refrigerant. Examples of the supercooling release agent include fine powders of ice nucleation substances such as silver iodide. When the main body 121 is cooled in a freezer, these fine powders become ice nuclei and suppress the supercooling temperature of the frozen refrigerant. Further, preferably, a small amount of gas is replaced, and further, cushioning properties and fit properties are enhanced by filling expanded polystyrene particles of about 0.5 mmΦ to 5 mmΦ. And the gas and the styrene foam particles exhibit a certain heat shielding effect, and the temperature of the part where the head contacts the ice pillow is reduced. In order for the flexible material to have flexibility in the ice pillow 120 that stores the frozen refrigerant, the flexible material needs to be plastically or elastically deformed even at the freezing temperature of the refrigerant. First, in order for a flexible material to plastically deform, the flexible material must be in a condition that allows micro-Brownian motion, and therefore the environmental temperature of the flexible material needs to be set above the glass transition point of the material. . Since the affected part cooling material is frozen in the freezer compartment of the refrigerator and the temperature of the freezer compartment is 0 ° C. to −10 ° C., the freezing temperature of the refrigerant is set higher than the temperature of the freezer compartment. Therefore, if the glass transition point of the flexible material of the present invention is set lower than −10 ° C., the flexible material can be plastically deformed at the freezing temperature of the refrigerant. That is, by forming the flexible container 4 from a flexible material having a glass transition point lower than −10 ° C., the plastic flexibility of the flexible material is guaranteed. Examples of the plastic having a glass transition point lower than −10 ° C. include polyethylene, acetyl resin, vinylidene chloride, and polypropylene. Examples of rubber having a glass transition point lower than −10 ° C. include polyisoprene, cis-polyisobutadiene, polyphenylene ether, polyisoprene, natural rubber, chloroprene, and trans-polybutadiene. In addition to the above, a regular copolymer having a glass transition point set to −10 ° C. or lower by alternating copolymerization, block copolymerization, or graft copolymerization of various monomers is also included.

<Configuration of IC tag>
FIG. 3 shows a configuration of the IC tags (RFID) 100a and 100b. The IC tag 101a mounted on the diaper 200 and the IC tag 100b provided on the ice pillow 120 have the same configuration. An IC tag similar to that shown in FIG. 3 may be provided on the cover (not shown) of the ice pillow 120 shown in FIG. 6 to control the temperature of the ice pillow 120. The RAM is a storage medium that receives a signal from the IC tag reading unit 34 and stores a program that causes the logic unit 110 to operate according to a predetermined flow. An EEPROM 102 stores an offset value, a temperature correction value, and the like corresponding to each temperature sensor 106. Also, body temperature information can be stored. The logic unit 110 may be a CPU that can control a more complicated processing flow. As the temperature sensor 106, a semiconductor type that outputs analog almost linearly with respect to temperature change, can be miniaturized and integrated with an IC tag, and has a temperature resolution of 0.05 ° C. between 35 to 42 ° C. However, a thermistor type or thermopile (thermocouple) type is also possible. Reference numeral 103 denotes a transmission / reception circuit for acquiring body temperature information of an IC tag (RFID) 100 having a temperature measurement unit provided in the subject P, 103a denotes an antenna, and 104 denotes a power supply unit. The power supply unit 104 supplies power to each part of the IC tags 100a and 100b having the temperature measurement unit when the body temperature information is read through the antenna unit 103a having a coil. Reference numeral 107 denotes an A / D converter, which A / D converts a body temperature signal generated by the temperature sensor 106 and an oscillation circuit (not shown). The IC tags 100a and 100b include the antenna 103a and have a size of about 5 mm × 5 mm and a thickness of about 1.5 mm. The IC tags 100a and 100b may have any frequency as long as they can communicate (transmit / receive) with an electromagnetic wave having a frequency that can pass through a living body, but preferably can transmit with an electromagnetic wave of 13.56 MHz. ing. Since the body temperature information can also be stored in the EEPROM 102, the body temperature information can be stored continuously even if the subject P is transferred to another mat. Further, it is possible to prevent the acquisition of incorrect information about the subject P, or to provide a security function by enabling encryption processing of a signal output from the antenna 103a.

In the data processing unit 37, the calculation result of the calculated heart rate, respiration rate, body movement magnitude, body temperature, etc. is stored in the storage unit 44 in the storage unit 44 in association with the ID of the subject P. At the same time, it is displayed on the display device 36. At the same time, transmission to the management site / medical site is possible. In this way, the state of the subject P is monitored.

The biometric data identifies the heart rate, the respiratory rate, and the like based on the characteristics of signals captured by the differential pressure sensor (relative pressure sensor) 20 and the absolute pressure sensor 21. For example, the heart rate and the respiration rate are separated into frequencies in the normal range through the filters 32 and 33. After conversion into a digital signal by the A / D conversion unit 35, the data processing unit 37 performs fast Fourier transform to obtain a fundamental frequency that becomes a peak spectrum, and extracts each of them.

<Biological information / Icy pillow temperature acquisition processing flow>
The measurement is started on the condition that the subject P is on the air mat 2 (recumbent, supine state). Every 10 to 60 minutes, a pressure signal is acquired (detected) by the differential pressure sensor (relative pressure sensor) 20 and the absolute pressure sensor 21 (step S1). Based on the characteristics of the acquired pressure signal, the heart rate, respiration rate, etc. are identified, and the heart rate, respiration rate, etc. are calculated (step S2). One pressure detection time is about 2 to 5 minutes. Body temperature information is transmitted every 10 to 60 minutes from the IC tag reading unit 34 to the IC tag 100a attached to the subject P. 13.56 MHz or 860 to 960 MHz (UHF band) electromagnetic waves (transmission and reception distance is The body temperature information of the temperature sensor 106 obtained in synchronism with the signal is read. In addition, temperature information on the outer surface of the ice pillow 120 is also transmitted to the IC tag 100 from the IC tag reading unit 34 at 13.56 MHz or 860 to 960 MHz (UHF band) every 10 to 20 minutes. The body temperature information of the temperature sensor 106 obtained in synchronization with the signal is read (step S3). The biological information and the ice pillow temperature information are stored in the storage unit 44 (step S4). This biological information and the temperature of the ice pillow are compared with a threshold value. For example, in the case of body temperature, the upper limit value is 37.0 ° C. and the lower limit value is 35.5 ° C. For example, the upper limit value is 120 beats / minute, the lower limit value is 30 beats / minute, and the respiration rate is, for example, the upper limit value is 90 / minute and the lower limit value is 10 / minute. Moreover, the upper limit of the temperature of the outer surface of the ice pillow 120 is set to 36.5 ° C., for example. If at least one of these pieces of biological information is determined to be abnormal, an alarm is generated (step S6) and notified to the doctor in charge at the management site / medical site. In addition, you may make it alert | report to a doctor's mobile phone etc. After confirming the condition of the subject P determined to be abnormal, the condition is reset as necessary (step S7). If it is not necessary, the monitoring (measurement) is terminated. If there is no abnormality, the process returns to step S1 as necessary, and the measurement of the biological information is repeated until a measurement end instruction is input. The biometric information measured and stored in the storage unit 44 calculates an average value, a maximum value, a minimum value, and a maximum value, and the data of the subject P together with the ID of the subject P is also stored in the storage unit 44 and a server (not shown). Remember. The biological information such as heart rate, respiratory rate, and body temperature stored in the storage unit 44 is trend-displayed on the display unit 36 and the display unit 11 as shown in FIG. In the display unit 36 and the display unit 11, the heart rate, the respiratory rate, and the body temperature are simultaneously displayed every hour (60 minutes), but one or any combination of these may be displayed. Further, by inputting medication data such as an antipyretic as memo information at the input unit 45 together with the date and time, it can be displayed together with the trend display of the biological information on the display unit 36 and the display unit 11. The same display can be performed on the display part (not shown) of the management site / medical site. As another condition for determining to generate an alarm, when the body temperature value exceeds one threshold, for example, 37.0 ° C., and the body temperature change rate (° C./minute) exceeds a predetermined value, for example, 1 ° C./60 minutes. An alarm can be generated when the value exceeds. In this case, when the body temperature value exceeds one threshold, for example, 37.0 ° C., the measurement interval is controlled to be shorter than the initial predetermined interval.

The analysis time (predetermined time) based on pressure detection can be set to an arbitrary time, not 2 to 5 minutes. The analysis time may be a time convenient for data analysis of one bedtime, and can be set within a predetermined bedtime instead of one bedtime. The optimum conditions are set according to the system size and analysis speed.

For example, the data processing unit 37 determines the health status of the subject P based on the following criteria.

Next, we will explain the abnormal monitoring during sleep and emergency calls. The data processing unit 37 of the terminal device 5 analyzes the biological data for a predetermined time (2 to 5 minutes) to calculate the heart rate, the respiration rate, and the like, and from the temperature information from the IC tag, these are abnormal. When the specified value range is exceeded, a temperature abnormality, heart rate abnormality, and respiratory rate abnormality are displayed on the display device, and an emergency call is reported to the management PC. The data processing unit 37 displays a heart rate abnormality and respiratory rate abnormality on the display device and sounds a buzzer. When the body movement continues for a certain period of time or more, the data processing unit recognizes a seizure and similarly performs display and a buzzer response, and notifies the management PC of the management site / medical site via the information communication network. In response to this, a medical staff such as a doctor at the management site / medical site feeds back a coping method through an information communication network, telephone, FAX, or the like.

The caregiver's burden can be reduced if the biometric information / ice pillow temperature information is acquired and displayed by the portable terminal 50 in addition to the terminal device 5. In FIG. 1, as with the terminal 5, the portable terminal 50 includes a display unit 11, an input unit 14, an external communication unit 12 that can communicate with the terminal device 5 and an information communication network such as the Internet, a storage unit 15, and a computer-readable device. A ROM 16 and a RAM 17 that store programs, predetermined conditions, and the like, and a control unit (CPU) 10 that processes the entire system are provided. The body temperature information of the subject P is directly read from the IC tag 100a, the IC tag reading unit 13 is provided for directly reading the temperature information of the ice pillow 120 from the IC tag 100b, and the notification is provided with a notification means such as light and a vibrator. If the unit 19 is provided, the burden on the caregiver can be reduced.
