The management computers 16 and 17 are a patient data list in which patient data are collected, a daily life data list in which daily life data for each patient is collected in time series, and defecation data for each patient in time series. A collection of defecation data lists is created, displayed on the display, and printed via a printer.

  The observation system 10 measures the distance between the end device 11 and the access point 12 based on the received power received by the PHS mobile terminal 13 from each access point 12, and determines the position on the coordinate of the end device 11 from the measured distance. By calculating, since the position of the dementia patient 18 is specified, the position specifying accuracy can be kept constant, and the position of the patient 18 can be specified accurately. Even if the location of the dementia patient 18 becomes unclear when the helper keeps an eye on the observation system 10, the present location of the patient 18 can be confirmed by the PHS mobile terminal 13, so the location is unknown. The patient 18 can be easily protected by the helper.

The observation system 10 can estimate the time-series movement path of the patient 18 by connecting the positions of the dementia patient 18 specified by the PHS mobile terminal 13 via the position specifying means in time series. The movement path followed by the dementia patient 18 can be identified, and the movement path and location of the patient 18 can be predicted in advance by analyzing the behavior pattern of the patient 18. The observation system 10 goes to the location of the dementia patient 18 predicted by the PHS mobile terminal 13, so that the helper can reliably protect the patient 18. Since the observation system 10 can compare the movement paths of the PHS mobile terminal 13 and calculate the difference L _S between the movement paths, the previous movement path and the subsequent movement path of the dementia patient 18 By comparing these, it is possible to analyze the progress of the patient's symptoms, which can be used as a reference for the patient's treatment. This observation system 10 can determine the difference between the previous movement path and the subsequent movement path. If these movement paths are greatly different, the observation system 10 is placed in an environment in which the dementia patient 18 can be constantly monitored. By restricting the behavior, it is possible to prevent a situation in which the patient 18 is unknown in advance.

  In the position specifying means, the calculated distance between the end device 11 and each access point 12 is defined as a radius, a circle centered on the access point 12 is drawn, and the point where the circumferences of these circles intersect is the position of the end device 11 In the observation system 10, since the intersection of at least three circles is the position of the end device 11, the time-series movement of the dementia patient 18 can be obtained by capturing the time-series movement of the intersection. Can be captured continuously. Even if the position of the access point 12 on the coordinates is unknown, the observation system 10 can measure the time-series position of the end device 11 and can reliably identify the current position of the dementia patient 18.

  When the end device 11 is carried by the dementia patient 18, the patient 18 may abandon it, and when the end device 11 is abandoned by the patient 18, the location of the patient 18 cannot be specified. However, in this observation system 10, the patient 18 is allowed to attach the adhesive surface 22 of the sheet 19 forming the end device 11 to the body of the dementia patient 18 without making the patient 18 aware of the presence of the end device 11. Unidentification of the location of the patient 18 due to the abandonment of the end device 11 can be prevented. Since the observation system 10 can prevent the end device 11 from falling off the dementia patient 18, it is possible to prevent the location of the patient 18 from being unidentified due to the end device 11 dropping off from the patient 18.

  The observation system 10 uses a wireless LAN ZigBee so that one access point 12 can communicate with a plurality of end devices 11, so that the positions of a plurality of patients can be specified, and the movement paths of a plurality of patients Can be estimated. The observation system 10 includes power consumption during communication between the ZigBee chip 20 of the end device 11 and the ZigBee chip 35 of the ZigBee adapter 34 and power consumption during communication between the ZigBee chip of the PHS mobile terminal 13 and the ZigBee chip 20 of the end device 11. Is 60 mW or less, the end device 11 and the adapter 34 can be used for a long period of time, and the charging interval and the battery replacement interval can be greatly extended. Can be prevented.

  In this dementia patient observation system 10, various data related to the dementia patient 18 can be transmitted only to either the portable terminal 14 owned by the doctor or the portable terminal 15 owned by the person in charge of the pharmaceutical company. . In the observation system 10, wireless LAN ZigBee is used as a short-range wireless communication standard, but Bluetooth (Bluetooth) can also be used in addition to ZigBee.
