  By the way, in a medical facility, patients who are forced to stay in the same posture for a long time, such as patients who cannot move immediately after surgery or patients who are bedridden, are often monitored. The most troublesome disease for such patients is pulmonary embolism, which can sometimes result in sudden death.

  It is medically known that pulmonary embolism develops when a thrombus occurs in a vein such as the lower limb or the upper arm, and this thrombus is carried to the lungs by the blood flow to clog the pulmonary artery. Dehydration is the most popular cause of blood clots. That is, in pulmonary embolism, it is presumed that the skin condition first changes due to dehydration, and then specific symptoms such as shortness of breath and palpitation appear. In addition to pulmonary embolism, right heart failure in which leg edema is seen can be cited as a disease in which such symptoms are presumed.

  Based on the medical knowledge as described above, according to the description in paragraph [0072] of Patent Document 1, skin IMP should be the first measurement item, and respiratory rate and heart rate should be the second measurement item. Is preferred. However, when skin IMP is used as the first measurement item, the following problems may occur.

  When skin IMP is used as the first measurement item, specific symptoms of pulmonary embolism such as shortness of breath or palpitation often do not appear when skin IMP is determined to satisfy the first determination condition. In addition, for patients at high risk of developing pulmonary embolism, elastic stockings or intermittent pneumatic compression may be used to improve blood flow and prevent pulmonary embolism. Already taken. For this reason, even if it was determined that the skin IMP met the first determination condition and the medical staff rushed to the patient, there was no possibility of taking any further measures, and there was a high possibility that the work would end in labor.

  In addition, the skin IMP easily varies depending on environmental factors such as ambient temperature and humidity. For this reason, when skin IMP is used as the first measurement item, it is determined that skin IMP satisfies the first determination condition, and the medical staff rushed to the patient. There was a high probability that it would end up in hard work.

  However, if the measurement of skin IMP itself is stopped, it is not preferable because the amount of judgment material for discrimination is reduced and the accuracy of discrimination is lowered. Therefore, there has been a demand for a mechanism that can perform appropriate discrimination without bothering medical staff more than necessary.

  An object of the present invention is to provide a biosensor control apparatus, an operation method and an operation program thereof, and a biosensor system that can perform appropriate discrimination without bothering medical staff more than necessary.

It is preferable to always measure the measurement items. In this case, the disease is preferably pulmonary embolism or right heart failure.

  In addition to the skin impedance, the body movement amount is preferably set as the second measurement item. In this case, it is preferable that the drive control unit changes the skin impedance measurement interval according to whether or not the measured value of the body movement amount satisfies a predetermined criterion.

  When the determination unit determines that the first measurement item satisfies the first determination condition, the determination unit preferably outputs a notification indicating that the first measurement item satisfies the first determination condition.

  When the determination unit determines that the first measurement item satisfies the first determination condition, the drive control unit waits for an input of a start instruction to start driving the second sensor unit, and the start instruction is input In addition, it is preferable to start driving the second sensor unit.

  It is preferable to provide a setting unit for setting the first determination condition.

  The determination unit preferably determines whether the second measurement item satisfies a preset second determination condition based on the measurement value of the second measurement item acquired by the second measurement value acquisition unit. In this case, the determination unit also determines whether or not the state in which the second measurement item does not satisfy the second determination condition continues for a preset period after the driving of the second sensor unit is started, and the drive control unit When it is determined that the state in which the second measurement item does not satisfy the second determination condition continues, it is preferable to stop the driving of the second sensor unit.

Further, the biosensor control server 12 determines whether or not a first determination condition 42 (see FIG. 5) set in advance is satisfied based on the measurement value of the first measurement item measured by the first sensor unit 20. When it is determined that the first measurement item satisfies the first determination condition 42, the driving of the second sensor unit 21 is started. Here, the case where the first measurement item satisfies the first determination condition 42 is a case where some abnormality is recognized in the state of the patient P.

  The client terminal 13 is a tablet computer carried by a medical staff such as a nurse N or a doctor D who monitors the state of the patient P. The client terminal 13 is operated by medical staff when the biosensor device 11 starts measurement of the first measurement item by the first sensor unit 20.

  In FIG. 2, the biosensor device 11 transmits various measurement values of the first measurement item and the second measurement item to the biosensor control server 12.

The drive stop command is output from the wireless transmission / reception unit 29 to each of the sensors 25 to 27. The respiratory rate sensor 25 and the heart rate sensor 26 are supplied with driving power from the battery 28 in response to the first driving start command, and start driving. Skin IMP sensor 27 is supplied with driving power from battery 28 in response to the second driving start command and starts to drive. Also, the sensors 25 to 27 are stopped from driving because the drive power supply from the battery 28 is cut off by the drive stop command.

  In FIG. 4, the computers constituting the biosensor control server 12 and the client terminal 13 have the same basic configuration, that is, a storage device 30, a memory 31, a CPU (Central Processing Unit) 32, a communication unit 33, and a display, respectively. 34, an input device 35, and a speaker 36. These are interconnected via a data bus 37.

  The storage device 30 is a hard disk drive built in a computer constituting the biosensor control server 12 or the like, or connected through a cable or a network, or a disk array in which a plurality of hard disk drives are connected. The storage device 30 stores a control program such as an operating system, various APs, screen data of various screens associated with these programs, and the like.

  The memory 31 is a work memory for the CPU 32 to execute processing. The CPU 32 loads the program stored in the storage device 30 into the memory 31 and executes processing according to the program, thereby comprehensively controlling each part of the computer.

  The communication unit 33 is a network interface that performs transmission control of various information via the network 14. The display 34 displays various screens according to the operation of the input device 35 such as a mouse, a keyboard, or a touch panel. The screen has an operation function by GUI (Graphical User Interface). A computer constituting the biosensor control server 12 and the like receives an operation instruction input from the input device 35 through a screen.

  In the following description, each part of the computer constituting the biosensor control server 12 is assigned a subscript “A”, and each part of the computer constituting the client terminal 13 is assigned a subscript “B”. To distinguish.

  In FIG. 5, the storage device 30A of the biosensor control server 12 stores an operation program 40 as an AP. The operation program 40 is an AP for causing a computer constituting the biosensor control server 12 to function as a biosensor control device.

  In addition to the operation program 40, the storage device 30A includes a measurement value table 41 (see also FIG. 7), a first determination condition 42, an item setting table 43 (see also FIG. 8), and a patient table 44 (see also FIG. 9). ) Is stored.

  When the operation program 40 is activated, the CPU 32A of the biosensor control server 12 cooperates with the memory 31 and the like to receive an instruction receiving unit 50, a drive control unit 51, a first measurement value acquisition unit 52, and a second measurement value acquisition. Functions as a unit 53, a measurement value management unit 54, and a determination unit 55.

  The instruction receiving unit 50 receives various instructions from the client terminal 13. Various instructions include a start instruction, an end instruction, a measurement value request instruction, and the like. The start instruction is an instruction to cause the biosensor device 11 to start measuring the respiration rate and the heart rate by the first sensor unit 20. The end instruction is an instruction to cause the biosensor device 11 to end the measurement. The measurement value request instruction is an instruction for requesting display of the latest measurement value at that time. These instructions include patient IDs, which are symbols and numbers for identifying individual patients P. Further, the measurement value request instruction includes a terminal ID which is a symbol or number for identifying each client terminal 13. The instruction receiving unit 50 outputs a start instruction and an end instruction to the drive control unit 51 and a measurement value request instruction to the measurement value management unit 54, respectively.

  The drive control unit 51 controls driving of the sensors 25 to 27. The drive control unit 51 transmits various drive control signals to the biosensor device 11. More specifically, when a start instruction is input from the instruction receiving unit 50, the drive control unit 51 transmits a first drive start command to the biosensor device 11, and when an end instruction is input from the instruction receiving unit 50, A drive stop command is transmitted to the biosensor device 11. In addition, when the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, the drive control unit 51 transmits a second drive start command to the biosensor device 11.

  Here, when the first sensor unit 20 is always driven, the start instruction is input by the medical staff without being influenced by the trend of the measurement values of the other measurement items as in the second sensor unit 21. After the start command is given, until the end command is input and the drive stop command is given, or after the start command is given by the medical staff and the first drive start command is given, the remaining battery power is exhausted. That is, the first sensor unit 20 is continuously driven until power is not supplied.

  The first measurement value acquisition unit 52 acquires the respiratory rate and heart rate measurement values (measurement values of the first measurement item) from the biosensor device 11. The second measurement value acquisition unit 53 acquires the measurement value of the skin IMP (measurement value of the second measurement item) from the biosensor device 11. Each of these acquisition units 52 and 53 outputs the acquired various measurement values to the measurement value management unit 54.

  The measurement value management unit 54 registers various measurement values from the acquisition units 52 and 53 in the measurement value table 41. The measurement value management unit 54 passes the measurement values of the respiratory rate and the heart rate among the various measurement values in the measurement value table 41 to the determination unit 55. In addition, the measurement value management unit 54 reads the latest various measurement values from the measurement value table 41 in response to the measurement value request instruction from the instruction receiving unit 50, and sets the read various measurement values as the transmission source of the measurement value request instruction. It transmits to the client terminal 13. The client terminal 13 that is the transmission source of the measurement value request instruction can be identified by the terminal ID included in the measurement value request instruction.

  The determination unit 55 determines whether the respiration rate and the heart rate satisfy the first determination condition 42 based on the respiration rate and heart rate measurement values from the measurement value management unit 54. If the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, the determination unit 55 outputs the determination result to the drive control unit 51. In addition, the determination unit 55 outputs a notification that it is determined that the respiration rate and the heart rate satisfy the first determination condition 42. The notification is transmitted to the client terminal 13.

  The first determination condition 42 is a condition for determining whether any abnormality has occurred in the state of the patient P based on the measured values of the respiratory rate and the heart rate. In the first determination condition 42, for example, a threshold of respiration rate and heart rate such as a respiration rate of 25 BrPM and a heart rate of 100 BPM, and a period of 1 minute or the like are set. The determination unit 55 determines that the respiratory rate and the heart rate satisfy the first determination condition 42 when the state where the respiratory rate and the heart rate are equal to or greater than the threshold value continues for a set period or longer.

  FIG. 6 shows changes in the driving state of the biosensor device 11 as determined by the determination unit 55. First, in the upper stage, the biosensor device 11 receives the first drive start command from the drive control unit 51 in response to the start instruction, and as shown by the rectangular thick frame and the symbols ST1 and ST2 "ON" The number sensor 25 and the heart rate sensor 26 start driving. Thereby, the measured values of the respiration rate and the heart rate are output from the sensors 25 and 26. At this stage, however, the skin IMP sensor 27 does not start driving, as shown by the square thick frame and the symbol ST3 “OFF”, and therefore the measured value of the skin IMP is not output.

  When the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42 as indicated by the middle oval frame and the symbol JM1, the biosensor device 11 is driven as shown in the lower step. In response to the second drive start command from the control unit 51, the skin IMP sensor 27 starts to be driven as indicated by "ON" in ST3. Thereby, in addition to the respiratory rate and the heart rate, the measured value of the skin IMP is also output.

  As shown in FIG. 7, in the measurement value table 41, the acquisition time and various measurement values acquired by the acquisition units 52 and 53 for the various measurement values of the respiratory rate, heart rate, and skin IMP are registered for each patient ID. Has been. In the measurement value table 41, for each patient P, for example, various measurement values for one hour are registered. The measurement value management unit 54 rewrites various measurement values with the oldest acquisition time to new various measurement values each time new various measurement values are input from the respective acquisition units 52 and 53. In addition, when the drive of the skin IMP sensor 27 is not started, naturally nothing is registered in the section of the measured value of the skin IMP.

  The measurement value management unit 54 attaches a patient ID when passing the measurement values of the respiratory rate and the heart rate from the measurement value table 41 to the determination unit 55. The determination unit 55 also attaches a patient ID to the drive control unit 51 when outputting the determination result determined that the respiratory rate and the heart rate satisfy the first determination condition 42. Furthermore, the determination unit 55 adds the patient ID to the notification.

  As illustrated in FIG. 8, the first measurement item and the second measurement item are registered in the item setting table 43.

It is registered separately. These IDs are inputted by the hand of the doctor D when the patient P to be worn with the biosensor device 11 is selected.

  As indicated by an arrow 2 in FIG. 5, the drive control unit 51 refers to the patient table 44 and identifies the biosensor device 11 that transmits various drive control commands. Specifically, the drive control unit 51 reads the device ID corresponding to the patient ID included in the start instruction or the end instruction from the instruction receiving unit 50 from the patient table 44, and sets the biosensor device 11 of the read device ID to the first one. It is assumed that 1 drive start command or drive stop command is transmitted. Further, the drive control unit 51 reads the device ID corresponding to the patient ID included in the determination result from the determination unit 55 from the patient table 44, and transmits the biosensor device 11 of the read device ID to the transmission destination of the second drive start command. And In the example of FIG. 9, when the start instruction or the end instruction or the patient ID included in the determination result is “P001”, the biosensor device 11 having the device ID “S001” is set as the transmission destination of various drive control commands. .

  The measurement value management unit 54 refers to the patient table 44 as shown by the arrow 3 in FIG. 5 and identifies the patient ID of the registration destination of various measurement values in the measurement value table 41. Specifically, the measurement value management unit 54 recognizes the patient ID corresponding to the device ID transmitted from the biosensor device 11 together with various measurement values in the patient table 44, and registers the recognized patient ID as the registration destination of various measurement values. And In the example of FIG. 9, when the device ID transmitted together with various measurement values is “S002”, the various measurement values are registered in the item of patient ID “P002” of the measurement value table 41.

  As shown by the arrow 4 in FIG. 5, the determination unit 55 refers to the patient table 44 and identifies the client terminal 13 that transmits the notification. Specifically, the determination unit 55 reads the terminal ID corresponding to the patient ID included in the various measurement values from the measurement value management unit 54 from the patient table 44, and sends the client terminal 13 of the read terminal ID to the notification destination. And In the example of FIG. 9, when the patient ID included in the various measurement values is “P005”, the three client terminals 13 with the terminal IDs “C010”, “C011”, and “C016” are set as the notification transmission destination.

The AP control unit 61 transmits various instructions to the instruction receiving unit 50.

  The AP control unit 61 displays the measurement value display screen 70 (see FIGS. 12 and 13) on the display 34B based on the measurement value from the measurement value management unit 54. Further, in response to the notification from the determination unit 55, the AP control unit 61 displays a notification screen 75 (see FIG. 14) on the display 34B, and outputs a warning sound such as a beep sound from the speaker 36B. If the client terminal 13 has a vibration function, the AP control unit 61 may activate the vibration function together with the display of the notification screen 75 and the output of warning sound.

  In FIG. 11, the instruction input screen 65 is provided with an input box 66 for inputting a patient ID, a start button 67, an end button 68, and a measured value button 69. When the patient ID of the desired patient P is input to the input box 66 and each button 67 to 69 is selected, various types including the patient ID input to the input box 66 from the AP control unit 61 to the biosensor control server 12. An instruction is sent. That is, a start instruction is transmitted when the start button 67 is selected, an end instruction is transmitted when the end button 68 is selected, and a measurement value request instruction is transmitted when the measurement value button 69 is selected.

  12 and 13, the measurement value display screen 70 displays the patient ID designated on the instruction input screen 65, the acquisition time of various measurement values, and the various measurement values. FIG. 12 shows a state in which measured values of respiratory rate and heart rate are displayed before the determination unit 55 determines that the respiratory rate and heart rate satisfy the first determination condition 42. On the other hand, in FIG. 13, after the determination unit 55 determines that the respiration rate and heart rate satisfy the first determination condition 42, the measurement value of skin IMP is displayed in addition to the measurement value of respiration rate and heart rate. Indicates the state. Reference numeral 71 denotes a confirmation button for deleting the measurement value display screen 70.

  In FIG. 14, the notification screen 75 displays a message that an abnormality is recognized in the patient P of the patient ID included in the notification, a confirmation button 76, and a measurement value button 77. The confirmation button 76 is a button for erasing the notification screen 75 in the same manner as the confirmation button 71 on the measurement value display screen 70. The measured value button 77 is a button having the same function as the measured value button 69 of the instruction input screen 65, and is a button for displaying the measured value display screen 70 of the patient P of the patient ID included in the notification. .

  Hereinafter, the operation of the above configuration will be described with reference to the flowchart of FIG. First, the biosensor device 11 is attached to the patient P selected by the doctor D. The doctor D inputs the patient ID of the patient P, the device ID of the biometric sensor device 11, and the terminal ID of the client terminal 13 of the medical staff in charge of the patient P. These are registered in the patient table 44.

  The doctor D operates the client terminal 13 to start the monitoring program 60 and displays the instruction input screen 65 on the display 34B. The doctor D inputs a start instruction via the instruction input screen 65. The start instruction is transmitted to the biosensor control server 12 (step S100).

  In the biosensor control server 12, when a start instruction is received (YES in step S200), a first drive start command is transmitted from the drive control unit 51 to the biosensor device 11 (step S210).

  In the biosensor device 11, when the first drive start command is received (YES in step S300), the respiration rate sensor 25 and the heart rate sensor 26 of the first sensor unit 20 are started to be driven (step S310). The measured values of the respiration rate output from the respiration rate sensor 25 and the heart rate output from the heart rate sensor 26 are transmitted to the biosensor control server 12 (step S320).

  In the biological sensor control server 12, the measurement values of the respiratory rate and the heart rate are acquired by the first measurement value acquisition unit 52 (step S220). These measurement values are registered in the measurement value table 41 by the measurement value management unit 54 and are output from the measurement value management unit 54 to the determination unit 55. Then, the determination unit 55 determines whether or not the respiration rate and the heart rate satisfy the first determination condition 42 (step S230). The measurement of the respiration rate and heart rate in step S220 and the determination in step S230 are performed while the determination unit 55 does not determine that the respiration rate and heart rate satisfy the first determination condition 42 (NO in step S240). I can continue.

  When the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42 (YES in step S240), a second drive start command is transmitted from the drive control unit 51 to the biosensor device 11, and the determination is made. A notification is transmitted from the unit 55 to the client terminal 13 (step S250).

  In the biosensor device 11, when the second drive start command is received (YES in step S330), driving of the skin IMP sensor 27 of the second sensor unit 21 is started (step S340). The measured value of skin IMP output from skin IMP sensor 27 is transmitted to biosensor control server 12 (step S350).

  In the biosensor control server 12, the measurement value of the skin IMP is acquired by the second measurement value acquisition unit 53 (step S260). The measured value of skin IMP is registered in the measured value table 41 by the measured value management unit 54. The acquisition of the measured value of skin IMP in step S260 is continued while the end instruction from the client terminal 13 is not received by the instruction receiving unit 50 (NO in step S280).

  On the other hand, in the client terminal 13, when the notification from the determination part 55 is received (it is YES at step S110), the notification screen 75 is displayed on the display 34B, and a warning sound is output from the speaker 36B (step S120).

  By outputting a notification that the respiration rate and the heart rate satisfy the first determination condition 42 from the determination unit 55, the client terminal 13 displays the notification screen 75 and outputs a warning sound. Thereby, the medical staff can be surely recognized that an abnormality has occurred in the state of the patient P.

  After confirming the patient P in which an abnormality has occurred on the notification screen 75, the medical staff inputs an end instruction via the instruction input screen 65. The end instruction is transmitted to the biosensor control server 12 (step S130). Note that the end instruction is also input when a predetermined monitoring period ends.

  In the biosensor control server 12, when a termination instruction is accepted (YES in step S280), a drive stop command is transmitted from the drive control unit 51 to the biosensor device 11 (step S290).

  In the biosensor device 11, when a drive stop command is received (YES in step S360), the drive of each sensor unit 25 to 27 is stopped (step S370). Although not shown in FIG. 15, the medical staff inputs a measurement value request instruction via the designation input screen 65 and causes the display 34B to display the measurement value display screen 70 of the patient P that is personally worried. You can also.

  Since the respiratory rate and heart rate are set as the first measurement items, and the respiratory rate sensor 25 and the heart rate sensor 26 of the first sensor unit 20 are always driven, the measured values of the respiratory rate and the heart rate are constantly measured. Compared to the case where the first measurement item is used, the medical staff is not bothered more than necessary.

  More specifically, when the determination unit 55 determines that the respiratory rate and heart rate satisfy the first determination condition 42, the patient P has specific symptoms such as shortness of breath and palpitation. Even if the patient P has already taken preventive measures such as elastic stockings and intermittent pneumatic compression, additional examinations such as chest X-ray, CT (Computed Tomography), and lung scintigraphy Measures to prevent seriousness such as medication and surgery can be taken. Further, in the resting state, the measured values of the respiratory rate and the heart rate do not vary greatly due to environmental factors as compared with the skin IMP. Except when patient P exercises violently, such as running up stairs, in the first place patient P is selected as a patient who must stay in the same posture for a long time in bed 16 of patient room 15, so that is also considered Hateful. Therefore, compared with the case where skin IMP is set as the first measurement item, even if the medical staff rushes to the patient in response to the notification, the possibility of ending the effort is low.

  Skin IMP is used as the second measurement item, and when determination unit 55 determines that the respiratory rate and heart rate satisfy first determination condition 42, driving of skin IMP sensor 27 is started, and the measured value of skin IMP is obtained. Since it is acquired, the measured value of skin IMP can be used as a judgment material for discrimination together with the measured values of respiratory rate and heart rate. Therefore, it is possible to perform appropriate discrimination as compared with the case where the measurement value of skin IMP is not acquired and the measurement value of skin IMP is not acquired. In other words, because the number of skin IMP measurement items increases in addition to the respiration rate and heart rate, even if individual measurement values fluctuate due to environmental factors, doctor D is in a state where it is easy to make a comprehensive judgment by mitigating the effect. It can be provided, and it can be made to judge accurately whether further measures, such as an additional test, should be implemented.

  Unless the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, the skin IMP sensor 27 does not start driving, and therefore wasteful power consumption can be suppressed.

[Second Embodiment]
Although the skin IMP is a measurement item that is highly likely to end the care of the patient P by the medical staff, the skin IMP is a measurement item that can quickly detect a sign of abnormality of the patient P. For this reason, even if there is a high possibility that the medical staff cares about the patient P, the skin IMP is also used as the first measurement item when the merit of detecting the sign of abnormality is high. It is also preferable to always measure the same as the measured values of respiratory rate and heart rate.

  Even if there is a high possibility that medical staff care will end in a laborious manner, the patient P who has a higher merit for quickly detecting an abnormal sign can be considered a patient P who has a relatively high risk of developing a disease. Therefore, in the second embodiment shown in FIGS. 16 to 18, the skin IMP is exceptionally set as the first measurement item for patients with a relatively high risk of developing a disease, and the measured value of the skin IMP is always measured. To do.

  In FIG. 16, in this embodiment, a risk determination unit 80 is constructed in the CPU 32 </ b> A of the biosensor control server 12. In addition, the patient table 81 according to the present embodiment is provided with a pulmonary embolism risk for each patient ID in which whether or not there is a risk of developing pulmonary embolism as a disease is registered. In FIG. 16, the storage device 30A, the CPU 32A, and the functional units such as the drive control unit 51 and the determination unit 55 are not shown. In FIG. 17 and the like thereafter, only the main part is illustrated, and the illustration of the unrelated part is omitted.

  The risk determination unit 80 is a risk that the patient P develops pulmonary embolism based on the attribute of the patient P and the pulmonary embolism onset risk determination condition (hereinafter abbreviated as risk determination condition) 82 stored in the storage device 30A. Determine. The attributes of the patient P used for risk determination are age, BMI (Body Mass Index), surgical history, past history, and medication history. In the risk determination condition 82, thresholds and keywords for each attribute are registered, such as age: 60 years or older, BMI: 25 or more, history of surgery: surgery performed within the past three months.

  In addition to the blood coagulation disorder and intravenous catheter placement shown in the figure, the keywords of past disease include hypercoagulable diseases such as antiphospholipid antibody syndrome and protein C deficiency, pelvic / hip / leg injury, nephrotic syndrome, Shinta many Examples include myeloproliferative diseases such as blood diseases and thrombocythemia. In addition, the presence or absence of smoking or the presence or absence of pregnancy may be added to the risk determination condition 82.

  The attribute of the patient P is recorded in the electronic medical record 84 in the electronic medical record server 83. The risk determination unit 80 transmits an acquisition request for the electronic medical record 84 using the patient ID registered in the patient table 81 as a search key to the electronic medical record server 83, and the electronic medical record server 83 transmitted in response to the acquisition request. Obtain a medical record 84.

  The risk determination unit 80 compares the attribute of the patient P of the electronic medical record 84 with the risk determination condition 82. When any one of the above attributes satisfies the risk determination condition 82, the patient P is determined to be at risk of developing pulmonary embolism. On the other hand, when none of the attributes satisfies the risk determination condition 82, it is determined that the patient P is not at risk of developing pulmonary embolism. The determination result by the risk determination unit 80 is registered in the pulmonary embolism risk section of the patient table 81. Note that it may be determined that there is a risk of developing pulmonary embolism only when all the attributes satisfy the risk determination condition 82. The attribute of the patient P may not be acquired from the electronic medical record 84 but manually input by a medical staff.

  In the present embodiment, the drive control unit 51 drives the second sensor unit 21 according to the determination result of the determination unit 55 when the risk determination unit 80 determines that there is no risk. That is, as in the first embodiment, when the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, a second drive start command is transmitted to the biosensor device 11, and the skin IMP The drive of the sensor 27 is started.

  On the other hand, when the risk determination unit 80 determines that there is a risk, the drive control unit 51 always drives the second sensor unit 21 as well as the first sensor unit 20, and performs the second measurement similarly to the first measurement item. Items are always measured. That is, for the patient P who has a relatively high risk of developing pulmonary embolism, the skin IMP is constantly measured in addition to the respiratory rate and heart rate.

  Specifically, as illustrated in FIGS. 17 and 18, when the start instruction is input from the client terminal 13, the drive control unit 51 has a risk of developing pulmonary embolism of the patient with the patient ID included in the start instruction. The patient table 81 is checked for the presence or absence. When “None” is registered in the item of the risk of developing pulmonary embolism in the patient table 81 as in the case of receiving a start instruction including the patient ID: P002 in FIG. As in the first embodiment, a first drive start command is transmitted to the biosensor device 11. As a result, as in the first embodiment, the respiration rate sensor 25 and the heart rate sensor 26 start driving.

  On the other hand, when “Yes” is registered in the pulmonary embolism onset risk section of the patient table 81 as in the case where the start instruction including the patient ID: P001 in FIG. 18 is received, the drive control unit 51 In addition to the first drive start command, the second drive start command is also transmitted to the biosensor device 11. Thereby, in addition to the respiration rate sensor 25 and the heart rate sensor 26, the skin IMP sensor 27 also starts driving.

  As described above, since the skin IMP sensor 27 is always driven for the patient P who has a relatively high risk of developing pulmonary embolism, the patient P who has a relatively high risk of developing pulmonary embolism is quickly given a sign of abnormality. Can be sensed. As for the patient P who has a relatively low risk of developing pulmonary embolism, there is an effect that the medical staff is not bothered more than necessary as in the first embodiment.

  Pulmonary embolism, which is cited as a cause of death for patient P who must stay in the same posture for a long time in bed 16 of patient room 15, is a disease for determining risk, and thus effectively prevents the severity of pulmonary embolism. can do.

  In addition to or instead of pulmonary embolism, the risk of developing right heart failure may be determined. Right heart failure is known to have lower leg edema as a precursor, and it is presumed that the skin condition changes first as in pulmonary embolism. Therefore, if the risk of developing right heart failure is determined and the skin IMP sensor 27 is always driven for the patient P who has a relatively high risk of developing right heart failure, the same effect as in the case of pulmonary embolism Is obtained.

[Third Embodiment]
In the first embodiment, only skin IMP is exemplified as the second measurement item, but the present invention is not limited to this. As in the third embodiment shown in FIGS. 19 and 20, in addition to the skin IMP, a body movement amount indicating the amount of movement of the patient P may be set as the second measurement item.

  As shown in FIG. 19, in the item setting table 90 of this embodiment, the first measurement item includes the respiration rate and the heart rate as in the first embodiment, and the second measurement item includes the body movement amount in addition to the skin IMP. Each is registered.

  In FIG. 20, the second sensor unit 96 of the biosensor device 95 of this embodiment includes a body movement amount sensor 97 in addition to the skin IMP sensor 27. The body movement amount sensor 97 measures a body movement amount indicating the amount of movement of the patient P, and outputs this as a measurement value of the second measurement item. In this case, the drive control unit 51 sets the target of the second drive start command as the skin IMP sensor 27 and the body movement amount sensor 97. Skin IMP sensor 27 and body movement amount sensor 97 are supplied with driving power from battery 28 in response to the second driving start command and start driving.

  The body movement amount is a measurement item that is closely related to a disease such as pulmonary embolism, in which the risk of onset increases as the time that the patient P stays in the same posture becomes longer, and is suitable as a judgment material for discrimination. For this reason, in addition to the skin IMP, the amount of body movement is also measured, so that more judgment materials are available for discrimination and more appropriate discrimination can be performed.

[Fourth Embodiment]
Thrombus that triggers the onset of pulmonary embolism can be suppressed by improving blood flow. For patients P who are unable to move immediately after surgery or who are bedridden, measures such as elastic stockings and intermittent pneumatic compression are taken as described above. For the patient P who can move by himself / herself, an appropriate exercise is instructed by the doctor D in order to improve blood flow. In the case of such a patient P who can move to some extent, the risk of developing pulmonary embolism is temporarily reduced during exercise, so it can be considered that monitoring may be relaxed during that time.

  Therefore, in the fourth embodiment shown in FIGS. 21 and 22, when the body motion amount is measured by the body motion amount sensor 97 in addition to the skin IMP as in the biosensor device 95 of the third embodiment, the body of the patient P The measurement interval of skin IMP is changed according to the amount of movement. More specifically, the measurement interval of the skin IMP when the patient P's body movement amount is relatively large is made longer than when the patient P's body movement amount is relatively small.

  As illustrated in FIGS. 21 and 22, the determination unit 55 determines whether or not the measured value of the body movement amount from the biosensor device 95 satisfies the determination criterion 100 recorded in the storage device 30 </ b> A. The determination result by the determination unit 55 is input to the drive control unit 51 as indicated by an elliptical frame and symbols JM2 and JM3. The drive control unit 51 transmits a measurement interval change command for causing the skin IMP sensor 27 to change the measurement interval of the skin IMP to the biosensor device 95 as a drive control command in accordance with the determination result from the determination unit 55.

  In the determination criterion 100, a threshold value and a period of body movement are set. The determination unit 55 determines that the measurement value of the body movement amount satisfies the determination criterion 100 when the state in which the measurement value of the body movement amount is smaller than the threshold value continues for a set period or longer. The case where the measured value of the body movement satisfies the criterion 100 is, for example, the case where the patient P is resting and the body movement is small. In this case, the risk of developing pulmonary embolism is considered to be relatively high. On the other hand, the case where the measured value of the body movement does not satisfy the criterion 100 is, for example, the case where the patient P is exercising and the body movement is large. In this case, the risk of developing pulmonary embolism is relatively low. Conceivable.

  FIG. 21 shows a case where the measured value of the body movement amount satisfies the determination criterion 100. In this case, the drive control unit 51 outputs a measurement interval change command for making the measurement interval of the skin IMP relatively short, for example, 5 seconds. On the other hand, FIG. 22 shows a case where the measured value of the body movement amount does not satisfy the determination criterion 100. In this case, the drive control unit 51 outputs a measurement interval change command for making the measurement interval of the skin IMP relatively long, for example, 60 seconds.

  Thus, since the measurement interval of the skin IMP by the skin IMP sensor 27 is changed depending on whether or not the measurement value of the body movement amount satisfies the determination criterion 100, the state in which the body movement amount is small continues for a predetermined period and pulmonary embolism. When the risk of developing IMP is high, the measurement interval of skin IMP is relatively short. When the risk of pulmonary embolism is low after a large amount of body movement continues for a predetermined period, the measurement interval of skin IMP is relatively long. be able to. When the risk of developing pulmonary embolism is high, the measurement interval of skin IMP becomes relatively short, so that more detailed measurement of skin IMP is possible. On the other hand, when the risk of developing pulmonary embolism is low, the measurement interval of skin IMP is relatively long, so that the power consumption can be reduced accordingly.

  The body movement amount sensor 97 is incorporated into the first sensor unit 20 with the body movement amount as the first measurement item, and the measurement intervals of the respiration rate and the heart rate are set according to whether or not the measurement value of the body movement amount satisfies the determination criterion 100. It may be changed.

[Fifth Embodiment]
Although the measured values of the respiratory rate and the heart rate do not vary greatly due to environmental factors as compared with the skin IMP, the determination unit 55 may erroneously determine that the respiratory rate and the heart rate satisfy the first determination condition 42. Although the nature is also slight, it cannot be thrown away.

  In the first embodiment, a start instruction for starting driving of the first sensor unit 20 is input to the drive control unit 51, and in response thereto, a first drive start command is transmitted from the drive control unit 51 to the biosensor device 11. However, the start instruction for starting the driving of the second sensor unit 21 is not input to the drive control unit 51, and immediately when the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, The second drive start command has been transmitted from the drive control unit 51 to the biosensor device 11. For this reason, even when an erroneous determination occurs in the determination unit 55, the drive of the skin IMP sensor 27 is inevitably started, and power is wasted correspondingly.

  Therefore, in the fifth embodiment shown in FIGS. 23 and 24, when the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, the driving of the second sensor unit 21 is started. Only when a start instruction for starting the driving of the second sensor unit 21 is input to the medical staff, a second driving start command is transmitted from the drive control unit 51 to the biosensor device 11 and the second is started. The driving of the sensor unit 21 is started. Hereinafter, the start instruction for starting the driving of the second sensor unit 21 is referred to as a second start instruction in order to distinguish from the start instruction for starting the driving of the first sensor unit 20 of the first embodiment.

  In the present embodiment, the AP control unit 61 displays the notification screen 105 illustrated in FIG. 23 on the display 34B in response to the notification from the determination unit 55. In the notification screen 105, in addition to a message indicating that an abnormality is recognized in the patient on the notification screen 75 of the first embodiment, whether or not to start the measurement of the skin IMP (drive of the second sensor unit 21 is started). A message for inquiring of the medical staff about whether or not to perform the determination) and a YES button 106 and a NO button 107 are displayed.

  When the YES button 106 is selected, a second start instruction is transmitted from the AP control unit 61 to the biosensor control server 12. On the other hand, when the NO button 107 is selected, the second start instruction is not transmitted and the notification screen 105 is deleted.

  In FIG. 24, in this embodiment, when the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42 (YES in step S240), the determination unit 55 transmits a notification to the client terminal 13 (step S251). .

  However, at this time, unlike the step S250 shown in FIG. 15 of the first embodiment, the second drive start command is not transmitted from the drive control unit 51 to the biosensor device 11. Therefore, in the biosensor device 11, the driving of the skin IMP sensor 27 of the second sensor unit 21 remains stopped.

  After the notification is transmitted from the determination unit 55 to the client terminal 13 in step S251, when the YES button 106 on the notification screen 105 is selected by the medical staff and a second start instruction is accepted (YES in step S252), drive control The unit 51 transmits a second drive start command to the biosensor device 11 for the first time here (step S253).

  As described above, when the determination unit 55 determines that the respiration rate and the heart rate satisfy the first determination condition 42, the input of the second start instruction is waited for input of the second start instruction, and the second start instruction is input. Since the driving of the two-sensor unit 21 is started, power is not wasted when an erroneous determination occurs in the determination unit 55.

  In FIG. 24, the flowcharts of the biosensor device 11 and the client terminal 13 are omitted, and the processes before step S220 and after step S260 are the same as those in the first embodiment, and thus are omitted. Furthermore, the steps added in the present embodiment are indicated by a one-dot chain line. The same applies to FIG.

[Sixth Embodiment]
The first determination condition 42 is set based on public medical standards and medical knowledge accumulated so far. For this reason, when a public medical standard is changed or new medical knowledge is discovered, it is necessary to reset the first determination condition 42 accordingly. Therefore, in the sixth embodiment shown in FIG. 25, the first determination condition 42 can be set.

  In FIG. 25, the setting unit 110 for setting the first determination condition 42 is constructed in the CPU 32A of the biosensor control server 12 of the present embodiment. The setting unit 110 sets the first determination condition 42 according to a condition setting instruction from the client terminal 13 by the hand of the medical staff. The condition setting instruction may be, for example, an instruction to lower the respiratory rate threshold value from 25 BrPM to 22 BrPM, or an instruction to extend the period threshold value from 1 minute to 2 minutes.

  By providing such a configuration for setting the first determination condition 42, when the public medical standards are changed or new medical knowledge is discovered, the first determination condition 42 is reset accordingly. be able to. In addition, the medical staff can freely customize the first determination condition 42.

  A relatively strict first determination condition 42 is set for a patient P with a high risk of developing a disease, and a relatively loose first determination condition 42 is set for a patient P with a low risk of developing a disease. The first determination condition 42 corresponding to the patient P can also be set.

  In addition, although the example which resets the 1st determination condition 42 by the hand of the medical staff was demonstrated in FIG. 25, you may reset the 1st determination condition 42 semiautomatically or automatically. For example, when the NO button 107 is selected on the notification screen 105 of FIG. 23, it is considered that an erroneous determination has occurred in the determination unit 55, and therefore the first determination condition 42 until then is relatively loose by the setting unit 110. By re-setting the conditions, erroneous determination from the next determination is prevented. Alternatively, a few days immediately after the operation day are set as a relatively strict first determination condition 42 by the setting unit 110, and a relatively loose first determination condition 42 is passed after the several days, etc. The first determination condition 42 may be reset according to the condition of the patient P. The operation date can be acquired from, for example, the operation history of the electronic medical record 84, or can be acquired manually by a medical staff.

[Seventh Embodiment]
In the first embodiment, it is determined whether or not the respiration rate and the heart rate that are the first measurement items satisfy the first determination condition 42, and it is determined that the respiration rate and the heart rate satisfy the first determination condition 42. In addition, the notification is transmitted from the determination unit 55 to the client terminal 13, but the same processing is performed for the skin IMP as the second measurement item as in the seventh embodiment shown in FIGS. May be.

  In FIG. 26, the determination unit 55 of the present embodiment determines whether or not the skin IMP satisfies the second determination condition 112 set in advance based on the measured value of the skin IMP from the biosensor device 11. When it is determined that the skin IMP satisfies the second determination condition 112, a notification to that effect is transmitted to the client terminal 13. In the following, in order to distinguish from the determination of whether or not the respiration rate and heart rate of the first embodiment satisfy the first determination condition 42, it is determined whether or not the skin IMP satisfies the second determination condition 112. This is referred to as second determination. Further, in order to distinguish from the notification that the respiratory rate and the heart rate of the first embodiment are determined to satisfy the first determination condition 42, the notification that the skin IMP is determined to satisfy the second determination condition 112 is the first notification. 2 written as notification.

  In FIG. 27, in the present embodiment, after acquiring the measured value of skin IMP in step S260, the determination unit 55 determines whether the skin IMP satisfies the second determination condition 112 (step S261). And when it determines with skin IMP satisfy | filling the 2nd determination conditions 112 (it is YES at step S262), a 2nd notification is transmitted to the client terminal 13 (step S263). The acquisition of the measured value of skin IMP in step S260, the second determination in steps S261 and S262, and the transmission of the second notification in step S263 are performed while the end instruction from the client terminal 13 is not received by the instruction receiving unit 50 ( NO) is continued in step S280.

  In this way, in addition to the respiration rate and the heart rate that are the first measurement items, the determination and notification processing is also performed for the skin IMP that is the second measurement item. If there is a notification for the skin IMP of the present embodiment following the notification for the number, the medical staff can grasp the more detailed state of the patient P, for example, the patient P is in a more pressing state. Note that the second determination condition 112 may be set by the setting unit 110 as in the first determination condition 42 of the sixth embodiment.

[Eighth Embodiment]
In the above seventh embodiment, while the end instruction is not received by the instruction receiving unit 50 (NO in step S280), it has been described in the aspect in which the acquisition of the measured value of the skin IMP in step S260 is continued, but if the end instruction is If the state in which the skin IMP does not satisfy the second determination condition 112 continues until the instruction is received by the instruction receiving unit 50, no action is taken on the medical staff, and accordingly, the skin IMP sensor 27 is driven accordingly. Electricity is wasted.

  Therefore, in the eighth embodiment shown in FIG. 28, when the state where the skin IMP does not satisfy the second determination condition 112 continues for a preset period after the driving of the skin IMP sensor is started, the skin IMP sensor 27 Stop driving.

  In FIG. 28, in the present embodiment, the determination unit 55 determines whether or not the skin IMP satisfies the second determination condition 112 (step S261), and the skin after the driving of the skin IMP sensor 27 is started. The duration of the state in which the IMP does not satisfy the second determination condition (NO in step S262) is counted. Then, as shown in step S264, the determination unit 55 compares the measured duration period with a preset period. When the measured duration is a preset period (YES in step S264), the determination unit 55 outputs a determination result to that effect to the drive control unit 51.

  When the drive control unit 51 receives a determination result from the determination unit 55 that the measured duration is a preset period, the drive control unit 51 issues a skin IMP sensor drive stop command to stop driving the skin IMP sensor 27. It transmits to the apparatus 11 (step S265). Thereby, in the biosensor device 11, the drive of the skin IMP sensor 27 is stopped. In the biosensor control server 12, the determination unit 55 returns to the state of step S220 before determining that the respiration rate and the heart rate satisfy the first determination condition 42.

  As described above, when the state in which the skin IMP does not satisfy the second determination condition 112 continues for a preset period after the driving of the skin IMP sensor is started, the driving of the skin IMP sensor 27 is stopped. Power consumption can be reduced.

[Ninth Embodiment]
When the biosensor device 11 is driven by the battery 28 as in the first embodiment, in order to avoid a situation in which the biosensor device 11 is left unattended because the remaining amount of the battery 28 runs out, A system that can inform the medical staff of the remaining amount is necessary. Therefore, in the ninth embodiment shown in FIG. 29 to FIG. 31, the remaining amount information of the battery 28 is acquired from the biosensor device 11, and the remaining amount information is output to the medical staff. I can tell you.

  In FIG. 29, a remaining amount information acquisition unit 115 and a remaining amount information output unit 116 are constructed in the CPU 32A of the biosensor control server 12 of the present embodiment. Also, the patient table 117 of this embodiment is provided with a remaining amount information item for each patient ID.

  The biosensor device 11 detects the remaining amount of the battery 28 and calculates the time that can be measured with the detected remaining amount, that is, the remaining measurable time. Then, this remaining measurable time is transmitted to the biosensor control server 12 as remaining amount information. The biosensor device 11 transmits the remaining amount information, for example, every 10 minutes. In addition, the biosensor device 11 attaches a device ID to the remaining amount information as with various measurement values. Note that the remaining amount of the battery 28 itself may be transmitted as the remaining amount information.

  The remaining amount information acquisition unit 115 acquires remaining amount information from the biosensor device 11. Then, the acquired remaining amount information is registered in the remaining amount information section of the patient table 117 corresponding to the device ID included in the remaining amount information. The remaining amount information output unit 116 reads the remaining amount information from the patient table 117 and transmits the read remaining amount information to the client terminal 13.

  For example, when the measurement value is transmitted from the measurement value management unit 54 in response to the measurement value request instruction, the remaining amount information output unit 116 also transmits the remaining amount information. Alternatively, when the remaining measurable time is equal to or less than a preset threshold value, the fact and the remaining amount information are transmitted.

  Based on the remaining amount information from the remaining amount information output unit 116, the AP control unit 61 displays the remaining measurable time on the measured value display screen 70, for example, as indicated by the dashed-dotted line frame and the symbol RT in FIG. . Alternatively, the remaining amount warning screen 120 shown in FIG. 31 is displayed on the display 34B. On the remaining amount warning screen 120, a message indicating that the remaining measurable time is equal to or less than the threshold value is displayed. Although illustration is omitted, a message indicating that the remaining measurable time or the remaining measurable time is equal to or less than the threshold may be displayed on the notification screen 75 of FIG. 14 or the notification screen 105 of FIG. Alternatively, after a start instruction is input on the instruction input screen 65, a display screen for the remaining measurable time may be displayed.

  Thus, since the remaining amount information of the battery 28 is acquired from the biosensor device 11 and the acquired remaining amount information is output, the remaining amount of the battery 28 can be reported to the medical staff as shown in FIGS. it can. For this reason, it is possible to avoid a situation in which the biosensor device 11 is left in a state where the remaining amount of the battery 28 runs out and measurement is impossible.

[Tenth embodiment]
In each said embodiment, although the biosensor apparatus which has a 1st sensor part and a 2nd sensor part was illustrated, like 10th Embodiment shown in FIGS. 32-35, a biosensor apparatus is further 3rd measurement item. You may have the 3rd sensor part which measures.

  In FIG. 32, the biosensor device 125 of the present embodiment includes a third sensor unit 126 in addition to the first sensor unit 20 and the second sensor unit 21 of the first embodiment. The third sensor unit 126 includes an electrocardiogram sensor 127 that measures an electrocardiogram waveform and outputs this as a measurement value of the third measurement item. The electrocardiogram sensor 127 starts driving in response to the third driving start command, and stops driving in response to the driving stop command.

  In the present embodiment, the determination unit 55 determines to determine the driving condition of the third sensor unit 126 including at least one of the start and stop of the driving of the third sensor unit 126. Further, the drive control unit 51 controls the driving of the third sensor unit 126 according to the driving condition determined by the determination unit 55.

  For example, as shown in FIG. 33, in the present embodiment, as in the seventh and eighth embodiments, the determination unit 55 performs a second determination that determines whether or not the skin IMP satisfies the second determination condition 112. (Step S261). The second determination in step S261 corresponds to the determination for determining the driving start condition of the third sensor unit 126.

  When the determination unit 55 determines that the skin IMP satisfies the second determination condition 112 (YES in step S262), a third drive start command is transmitted from the drive control unit 51 to the biosensor device 125, and the determination unit 55 A second notification is transmitted to the client terminal 13 (step S266).

  In the biosensor device 125, driving of the electrocardiogram sensor 127 is started by the third driving start command. Thereby, as shown to step S267, in the biosensor control server 12, the measured value of the electrocardiogram waveform is acquired. The acquisition of the measured value of the electrocardiogram waveform in step S267 is continued while the end instruction from the client terminal 13 is not received by the instruction receiving unit 50 (NO in step S280).

  Or as shown in FIG. 34, the determination part 55 performs the 3rd determination which determines whether an electrocardiogram waveform satisfy | fills the 3rd determination conditions preset (step S268). If it is determined that the electrocardiogram waveform satisfies the third determination condition (YES in step S269), a third notification to that effect is transmitted to the client terminal 13 (step S270).

  Further, the determination unit 55 measures the duration of the state in which the electrocardiogram waveform does not satisfy the third determination condition (NO in step S269) after the drive of the electrocardiogram sensor 127 is started. Then, as shown in step S271, the determination unit 55 compares the measured duration period with a preset period. When the measured duration is a preset period (YES in step S271), the determination unit 55 outputs a determination result to that effect to the drive control unit 51. The determination in step S271 corresponds to the determination for determining the driving stop condition of the third sensor unit 126.

  When the drive control unit 51 receives a determination result from the determination unit 55 that the measured duration has been set in advance, the biosensor device 11 issues an electrocardiogram sensor drive stop command for stopping the drive of the electrocardiogram sensor 127. (Step S272). Thereby, in the biosensor device 11, the drive of the electrocardiogram sensor 127 is stopped. In the biosensor control server 12, the determination unit 55 returns to the state of step S260 before determining that the skin IMP satisfies the second determination condition 112.

  As described above, the determination unit 55 uses the biosensor device 125 including the third sensor unit 126 in addition to the first sensor unit 20 and the second sensor unit 21 to determine the driving condition of the third sensor unit 126. Since the driving of the third sensor unit 126 is controlled in accordance with the determined driving condition, it is possible to perform more appropriate discrimination as the number of measurement items increases, and the third sensor unit 126 is driven conditionally. By doing so, wasteful power consumption can be suppressed.

  When the measurement value of the electrocardiogram waveform is acquired by the biosensor control server 12, as shown in FIG. 35, the measurement value display screen 70 displays the electrocardiogram waveform in addition to the respiration rate, heart rate, and skin IMP. Is displayed.

  Similarly to the fifth embodiment, when the determination unit 55 determines that the skin IMP satisfies the second determination condition 112, the medical staff selects whether to start driving the third sensor unit 126, Only when a start instruction to start driving the third sensor unit 126 is input, a third drive start command is transmitted from the drive control unit 51 to the biosensor device 11 to start driving the third sensor unit 126. Also good. Further, similarly to the sixth embodiment, the third determination condition may be set by the setting unit 110.

  In addition to the respiratory rate, heart rate, skin IMP, body movement amount, and electrocardiogram in each of the above embodiments, body surface temperature and blood pressure may be used as measurement items.
