Further, it is possible to prevent acquisition of wrong care recipient P information, or to provide a security function by enabling encryption processing of a signal output from the antenna 103a.

In the data processing unit of the CPU 50, the result of calculating the body temperature and the like is stored in the storage unit 55 in correspondence with the ID of the care recipient P and displayed on the display device 51. At the same time, transmission to the management site / medical site 7 is possible. In this way, the status of the cared person P is monitored.

Reference numeral 200 denotes an IC tag (first temperature measuring unit) with a temperature sensor that is built in a battery and configured to store body temperature (temperature) information at a set time (minute) interval for a maximum of 360 days. The IC tag with the temperature sensor (first temperature measuring unit) is attached to an appropriate place of the cared person P, and the body temperature for a normal predetermined time, for example, 24 hours is measured and stored.

Information such as vaccination (inoculation of influenza, mumps, polio, pertussis, rubella, measles, tuberculosis, etc.) is input by the input unit 54 and stored in the storage unit 55. Since the body temperature information can be stored in the EEPROM 202 together with the ID information of the cared person P, the body temperature information can be continuously stored even if the cared person P is transferred to another bed or another room. In addition, it is possible to prevent the acquisition of information on the wrong care recipient P and to provide a security function by enabling encryption processing of signals output from the antenna 203a. Depending on the measurement interval, the IC tag 200 can measure and store body temperature for about 5 days in 2 minutes, about 14 days in 5 minutes, and about 1 month in 10 minutes.

<Structure of ice pillow>
In FIG. 3, the ice pillow 120 is provided on the outer surface of the main body 121, the grip portion 122, the clamp 123, and the main body 121 having flexibility in the range of 0 to 40 ° C. made of latex, synthetic rubber, elastic synthetic resin, or the like. IC tag (RFID) 100, which is used with ice and water inside, covered with ice cover 120 and covered with hook-and-loop fastener 124 or the like, or a freezing refrigerant ( A freezing type cooling member (not shown) is pre-filled, and an ice pillow 120 provided with the IC tag 100, or a type in which the ice pillow 120 is covered with a cover 125 and locked with a hook-and-loop fastener 124 or the like is used.

The frozen refrigerant is a solution or liquid that is liquid or liquid at room temperature and has 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 be flexible in the main body 121 that stores the freeze-type refrigerant, the flexible material needs to be plastically deformed 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.

<Body temperature information, etc./Process flow for obtaining ice pillow temperature>
With reference to the flow of FIG. 4, the processing flow of temperature information etc./ice pillow temperature acquisition will be described. Either the terminal 5 or the portable terminal 50a may be used, or both may be performed. The IC tag 100 attached to the care receiver P transmits 13.56 MHz electromagnetic waves from the IC tag reading units 13 and 53 every 10 to 60 minutes (transmission / reception distance is about 3 cm to 1 m) (step S1). ), The body temperature information of the temperature sensor 106 obtained in synchronization with the signal is read. The temperature information of the outer surface of the ice pillow 120 is also transmitted from the IC tag reading units 13 and 53 to 13.56 MHz electromagnetic waves to the IC tag 100 at a predetermined interval, for example, every 10 to 20 minutes (transmission / reception distance is about 10 cm to 1 m). The temperature information of the temperature sensor 106 obtained in synchronization with the signal is read (step S2). The body temperature information and the ice pillow temperature information are stored in the storage units 15 and 55 (step S3). This body temperature information and the temperature of the ice pillow are compared with a threshold value (step S4). 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. In addition, as biological information, pulse and blood oxygen saturation (SPO ₂ ) are measured by connecting a connection terminal of a pulse oximeter (not shown) to the connection terminal 12a of the terminal 5 or the portable terminal 50a, for example, or separately. The measured pulse and blood oxygen saturation (SPO ₂ ) are input together with the year, month, day, hour and date at the input units 14 and 54 and stored in the storage units 15 and 55. The pulse has a predetermined value (threshold) as an upper limit of 120 beats / minute, a lower limit of 30 beats / minute, and the blood oxygen saturation (SPO ₂ ) has a predetermined value (threshold) of 90 as a lower limit, for example. It is said. Further, the temperature of the outer surface of the ice pillow 120 is, for example, a predetermined value (threshold value) as an upper limit value of 36.5 ° C. When at least one of these pieces of biological information is determined to be abnormal, an alarm is generated (step S5), and the doctor in charge at the management site / medical site is notified. In addition, you may make it alert | report to a doctor's mobile phone etc. After confirming the condition of the infant P determined to be abnormal, it is reset if necessary (step S6). 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 biological information such as body temperature, blood oxygen saturation (SPO ₂ ), pulse, etc. stored in the storage units 15 and 55 is displayed in a trend on the display units 11 and 51 as shown in FIG. In one example shown in FIG. 6, there are trend values of body temperature, blood oxygen saturation (SPO ₂ ), and ice pillow temperature. After using the ice pillow 120, it can be seen that the body temperature is lowered and the value of blood oxygen saturation (SPO ₂ ) is improved. In addition, the antipyretic effect and replacement time of the ice pillow can be glimpsed. Items for trend display can be arbitrarily combined with the function keys 14a. In this way, if you measure with a pulse oximeter, or superimpose and display the pulse and blood oxygen saturation (SPO ₂ ) being measured, respiratory diseases caused by infections such as influenza and RS (Respiratory Syncytial) virus are easy. Can grasp. Further, by inputting medication data such as an antipyretic as memo information at the input unit 14 together with the date and time, it can be displayed together with the trend display of the biological information on the display units 11 and 51. The same display can be made 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.

<Other functions and operations>
Other functions and operations will be described in detail below.
(1) Time setting When a battery (not shown) is inserted into the portable terminal 50, necessary data including the current year / month / day / hour and its sum value is read from the ROM 16 which is a nonvolatile memory. When the mobile terminal 50 is turned on or while the battery is inserted in the mobile terminal 50, a signal is sent to the CPU (calculation processing unit) once every hour from the clock (timer) in every step (not shown). When the CPU 10 receives the signal, it writes the current year / month / day / hour in the ROM 516.

  Next, the read sum value of the current year, month, date, and hour is calculated, and it is confirmed whether it is equal to the read sum value. If they are equal, the process proceeds to the SLEEP state. If they are not equal, it is determined that the read value is invalid, and the error flag FLAGerr is set (= 1).

Next, it waits in the SLEEP state until the power is turned on.

When the power is turned on, FLAGerr is confirmed, and if it is a predetermined condition, for example, if it is other than 1, the operation proceeds to a temperature detecting operation. If FLAGerr is 1, the process proceeds to date / time input processing. Here, a screen prompting the user to input the date / time is displayed, and the user inputs the current year / month / date / time according to the screen. As another method, regardless of the value of FLAGerr, a method of always shifting to the date / time input process when the power is turned on for the first time after inserting the battery is also conceivable. In this case, the sum value and sum check functions are unnecessary. In addition, the provision of the radio timepiece increases the cost but eliminates the sum value and sum check functions. In this way, the user can quickly and easily set the year, month, day, hour, and minute, and even if the current year, month, day and hour of the EEPROM is damaged, the subject P can quickly set the correct date. Yes. Thus, the set current time is displayed on the display unit 11 by the calendar function based on the clock function and the calendar. That is, while AM and PM indicating AM and PM are displayed, the current time is displayed, and the date is updated every time the time count by the clock function elapses 24 hours, and this date is displayed on the display unit 11 by the calendar function. Is done. In addition, “year” may be displayed on the display unit 11.

<Other usage patterns>
The portable terminal of the present invention can be used as a normal electronic thermometer. In this case, when the temperature is measured for a predetermined time (about 1 to 5 minutes) by attaching the first temperature measuring unit to an appropriate place on the body of the care recipient P, the temperature information is stored in the EEPROM 202 along with the time. Remembered. The stored body temperature information is stored in the storage unit 15 of the portable terminal 50 from the external transmission unit 203 via the signal line via the external communication unit 12 (the reading start switch may be provided to instruct reading start).
