FIG.

The vital information measurement unit 126 includes at least a skin thermometer 126a that measures the skin temperature of the person 2 to be measured. The skin thermometer 126a is provided on the surface of the housing 120 that contacts the wrist of the measurement subject 2 so that the detection element is exposed. The correct wearing state of the vital measurement terminal 12 is a state in which the skin thermometer 126a is in close contact with the measurement site of the measurement subject 2 (that is, the skin of the wrist portion). It is possible to accurately measure the skin temperature of the person 2 to be measured. On the contrary, if the skin thermometer 126a is not worn correctly, the skin temperature of the measurement subject 2 may not be measured correctly.

The vital information measurement unit 126 may include sensors (for example, a blood pressure monitor, a pulse monitor, etc.) that measure vital information other than the position specifying unit 10a. Also, the vitals measuring terminal 12 may include sensors other than the sensors for measuring vitals information (for example, an acceleration sensor, a barometer, an illuminance meter, etc.).

The vital measurement terminal 12 configured as described above intermittently (for example, at predetermined time intervals) transmits the vital information measured by the vital information measurement unit 126 to the management device 10 via the access point 11. do. A terminal ID, which is an identification ID of itself, is assigned to the vital measurement terminal 12, and when a signal is transmitted, this terminal ID is added to the terminal and transmitted.

Next, how the functions of the vital information collection system 1 of the present invention are realized by the management device 10, the access point 11, and the vital measurement terminal 12 will be described. FIG. 6 shows a functional block diagram of the management device 10. As shown in FIG. The management device 10, as shown in FIG. 6, includes a position specifying section 10a and a mounting error detection section 10b.

The storage unit 106 of the management device 10 stores in advance a position specifying program that implements the function of the position specifying unit 10a. Then, the management device 10 executes this position specifying program and sequentially acquires the current position of the vital measurement terminal 12 in the following procedure, thereby realizing the function of the position specifying section 10a.

The position specifying program is read and executed by the control unit 101 of the management device 10, and the access point ID indicating the installation position of the access point 11 and the vital measurement terminal 12 received by the access point 11 are obtained from the access point 11. A response signal including a terminal ID is sequentially received via communication section 107, and information included in the received response signal is stored in storage section 106 in association with the reception time.

When the access point 11 receives a signal including the terminal ID from the vital measurement terminal 12 , the access point 11 transmits to the management device 10 a response signal in which the access point ID is added to this signal.

By configuring the position specifying unit 10 a in this way, the current position information of the vital measurement terminal 12 worn or possessed by the person to be measured 2 can be sequentially collected and stored in the storage unit 106 . Note that the method of specifying the position of the vital measurement terminal 12 and the method of collecting the specified positions are not limited to the above methods, and any method may be used. For example, the vital measurement terminal 12 may be provided with positioning means such as a GPS receiver, and the vital measurement terminal 12 may transmit its own current position to the management device 10 .

The storage unit 106 of the management device 10 stores in advance a mounting error detection program that implements the function of the mounting error detection unit 10b. Then, the management device 10 executes the abnormal wearing detection program to realize the function of the abnormal wearing detection unit 10b, and the skin temperature of the person to be measured 2 measured by the vital measurement terminal 12 and the environmental thermometer 112 An abnormality in the wearing state of the vital measurement terminal 12 is detected based on the measured environmental temperature.

Specifically, the wearing abnormality detection unit 10b relays the skin temperature of the person to be measured 2 measured and transmitted by the vital measurement terminal 12 and the environmental thermometer of the access point 11 that relays the transmission information from the vital measurement terminal 12. The environmental temperature measured at 112 is constantly monitored, and if the difference between the two is less than a predetermined value, it is detected as an abnormality in the mounting state. In other words, the abnormal wearing detection unit 10b defines a state in which the skin thermometer 126a is in close contact with the wrist, which is the part to be measured of the person 2 to be measured, as a normal wearing state. When the vital measurement terminal 12 is not worn normally (for example, when the vital measurement terminal 12 is not in close contact with the wrist of the person to be measured 2), the temperature measured by the vital measurement terminal 12 as the skin temperature is not measured. It deviates from the actual skin temperature of the subject 2 and approaches the ambient temperature of the vital measurement terminal 12 . Therefore, when the device is not properly worn, the ambient temperature of the vital measurement terminal 12 becomes substantially equal to the environmental temperature measured by the environmental thermometer 112, and the abnormal wearing detector 10b determines that the difference between the two is a predetermined value. If the temperature drops below (for example, 1° C.), it is detected as an abnormal mounting state. When the environmental temperature is in a temperature range close to human body temperature (for example, 35° C. to 38° C.), the abnormal wearing detection unit 10b may not detect abnormal wearing conditions by means of the abnormal wearing detection program.

When detecting an abnormality in the mounting state, the mounting abnormality detection unit 10b notifies the abnormality in the mounting state. For example, on the display unit 105 of the management device 10, the terminal ID of the vitals measuring terminal 12 (or the name of the person to be measured 2 wearing the vitals measuring terminal 12, etc.) and the position specifying unit It is preferable to display the position of the vital measurement terminal 12 specified in 10a and to emit an alarm sound. Alternatively, the same information as displayed on the display unit 105 is configured to be notified to necessary contacts (person in charge of nursing or care of the measurement subject 2, administrator of the vital information collection system 1, etc.). may

With such a configuration, it is possible to quickly detect an abnormality in the wearing state of the vital measurement terminal 12 and take measures such as re-wearing. Therefore, since it becomes easy to maintain the state in which the vitals measuring terminal 12 is correctly attached, the reliability of the vitals information acquired by the vitals information collection system 1 can be improved. In addition, it is possible to easily distinguish whether the measured value indicates an abnormal value due to an abnormality in the wearing state or whether the vital information of the person to be measured 2 is actually an abnormal value.

The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying constituent elements without departing from the scope of the present invention at the implementation stage. For example, in the above embodiment, the access point 11 has the environmental temperature gauge 112, but the access point 11 may not have the environmental temperature gauge 112 and may have an external environment temperature measuring device. In this case, for each access point 11, an environmental temperature measuring device corresponding to the position of the access point 11 is linked in advance, and the environmental temperature measuring device linked to the access point 11 including the vital measurement terminal 12 in the communication area. It is preferable that the management device 10 acquires the temperature measured in . In such a configuration, the environmental temperature measuring device should be configured to be able to communicate with the access point 11 , and the management device 10 should acquire the temperature measured by the environmental temperature measuring device via the access point 11 . Alternatively, the management device 10 may acquire the temperature measured by the environmental temperature measuring device through a communication path that does not pass through the access point 11 .

In the above-described embodiment, the access point 11 transmits the vital information from the vital measurement terminal 12 to the management device 10 with the environmental temperature information measured by the environmental thermometer 112 added. The temperature measured by the environmental thermometer 112 may be transmitted in response to a request from the management device 10 .

In the above embodiment, the abnormal wearing detection unit 10b relays the skin temperature of the person to be measured 2 measured and transmitted by the vital measurement terminal 12 and the environment of the access point 11 that relays the information transmitted from the vital measurement terminal 12. When the difference from the environmental temperature measured by the thermometer 112 is equal to or less than a predetermined value, it is detected that the mounting state is abnormal, but the condition for determining abnormality by the mounting abnormality detection unit 10b is not limited to this. For example, the wearing abnormality detection unit 10b may detect an abnormality in the wearing state when the skin temperature measured by the vital measurement terminal 12 changes following changes in the environmental temperature at the position of the vital measurement terminal 12. . Specifically, when the environmental temperature changes with the position of the vital measurement terminal 12 or with the passage of time, it is preferable to detect an abnormality in the wearing state when the skin temperature changes accordingly.

In order to make more active use of such followability to the environmental temperature, the management device 10 changes the set temperature of the air conditioner located at the vital measurement terminal 12 to change the environmental temperature. If the skin temperature changes in accordance with the change, it should be detected as an abnormality in the wearing state. Note that instead of always changing the set temperature of the air conditioner, the set temperature of the air conditioner is changed when the difference between the ambient temperature and the skin temperature is less than a predetermined value (that is, when an abnormality in the wearing state is suspected). It is preferable to configure as follows.

Further, in the above embodiment, the access point 11 that wirelessly communicates with the vital measurement terminal 12 has the environmental thermometer 112 , and the position of the vital measurement terminal 12 is specified within the wireless communication area covered by the access point 11 . Therefore, the position of the vital measurement terminal 12 and the environmental thermometer 112 corresponding to the position naturally correspond. However, if the method by which the position specifying unit 10a specifies the position of the vital measurement terminal 12 is different from that in the above embodiment, the management device 10 stores in advance the environmental thermometers 112 corresponding to each position in the measurement target area. 106, and the wearing abnormality detecting unit 10b detects the wearing state of the vital measuring terminal 12 based on the environmental temperature measured by the environmental thermometer 112 corresponding to the position of the vital measuring terminal 12 specified by the position specifying unit 10a. should be configured to detect abnormalities in

Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. Further, for example, a configuration in which some components are deleted from all the components shown in the embodiments is also conceivable.
