Description

  The present invention relates to a medical system.

  Various techniques for monitoring patient status in hospitals are known. As one of the techniques, there is a technique in which a transmitter is attached to a patient, the condition of the patient is measured by the transmitter, and transmitted to a remote display device. The transmitter has an electrocardiogram electrode or the like for measuring the patient's condition, and measures the patient's condition via the electrode or the like. The display device displays the patient status received from the transmitter, and a medical staff such as a nurse can monitor the patient status from a location away from the patient such as a nurse station.

  If the electrodes are removed from the patient's body, the patient's condition cannot be measured. In this case, the transmitter detects the abnormality and notifies the display device, and an alarm is generated in the display device. Thereby, the medical staff can detect abnormality and perform necessary treatment.

  However, electrocardiogram electrodes or the like are generally required to be replaced or maintained by medical staff at regular intervals. If an alarm is generated even when a medical staff removes an electrode, etc. from a patient for replacement or maintenance, other medical staff may be wasted and the reliability of the alarm may be lost. There is a problem. In relation to this problem, Patent Literature 1 discloses a technique for stopping the generation of an alarm during treatment by a medical staff by performing an alarm stop operation in advance in a nurse call system.

JP 2007-282878 A

  However, in the technique disclosed in Patent Document 1, if the medical staff does not manually perform the alarm stop operation, the generation of the alarm cannot be suppressed, and it takes time for the medical staff. In addition, if the medical staff forgets to perform an alarm stop operation, an unnecessary alarm will be generated.

  This invention is made | formed in view of the said situation, and it aims at providing the medical system which can suppress an unnecessary alarm, without performing manual operation.

  The medical system includes a mobile terminal, a transmitter, and a receiver. The portable terminal is carried by medical staff and transmits preset identification information. The transmitter acquires and transmits the patient's biological information. The receiver receives biological information from the transmitter. When the transmitter can communicate with the mobile terminal, the transmitter acquires the identification information from the mobile terminal and transmits the identification information to the receiver. It has a transmission part which transmits alarm information to a receiver. When receiving the technical alarm information from the transmitter, the receiver determines whether or not the identification information is received. If the identification information is received, the receiver suppresses the alarm and does not receive the identification information. In some cases, it has a control unit that does not suppress alarms.

  The medical system includes a mobile terminal, a transmitter, and a receiver. The transmitter is carried by medical staff and transmits preset identification information. The transmitter acquires and transmits the patient's biological information. The receiver receives biological information from the transmitter. When the transmitter is communicable with the portable terminal, the transmitter has a transmitter that acquires identification information from the portable terminal and transmits the identification information to the receiver. When receiving the identification information from the transmitter, the receiver has a notification unit that notifies that the medical staff is responding.

  According to the present invention, when the receiver receives the technical alarm information from the transmitter, if the identification information transmitted from the portable terminal carried by the medical staff is received, the alarm is suppressed and the identification information is received. If not, do not suppress the alarm. Thereby, an unnecessary alarm can be suppressed without the medical staff who performs replacement and maintenance of the measurement unit manually performing an operation to suppress the alarm.

(First embodiment)
FIG. 1 is a diagram illustrating a schematic configuration of a medical system according to the first embodiment.

  The medical system of the first embodiment is provided in a hospital, for example.

  As illustrated in FIG. 1, the medical system 100 includes a mobile terminal 200, a transmitter 300, and a receiver 400.

  The portable terminal 200 is carried by, for example, a nurse N1 who is a medical staff, and transmits preset identification information.

  The transmitter 300 is attached to, for example, a patient in a hospital room, acquires biological information of the patient, and transmits it by a wireless signal. The transmitter 300 can receive the identification information transmitted by the mobile terminal 200 and transmits the received identification information.

  The receiver 400 is installed in a nurse station, for example, and displays biometric information received from the transmitter 300 on a display or the like. The receiver 400 can receive the identification information received and transmitted by the transmitter 300.

  Each configuration will be described in detail.

  FIG. 2 is a block diagram illustrating a functional configuration of the medical system according to the first embodiment.

  As shown in FIG. 2, the portable terminal 200 includes an identification information storage unit 210 and an identification information transmission unit 220.

  The identification information storage unit 210 stores identification information for identifying medical staff using the mobile terminal 200. The identification information is, for example, an identification ID for identifying individual medical staff. Alternatively, the identification information may be a number, symbol, name or the like indicating a ward or floor to which a medical staff belongs, a medical department, or the like.

  The identification information transmission unit 220 acquires the identification information set in the identification information storage unit 210 and repeatedly transmits the acquired identification information. The identification information transmission part 220 transmits identification information within the said range using the radio signal which has a range about 1-2 m, for example.

  The transmitter 300 includes a measurement unit 310, a technical alarm detection unit 320, an identification information reception unit 330, and a transmission unit 340.

The measurement unit 310 is a sensor that is attached to a patient's body and detects biological information, and is, for example, an electrocardiogram measurement electrode (ECG electrode), a blood oxygen saturation measurement probe (SpO ₂ probe), or the like. The biological information detected by the measurement unit 310 is, for example, an electrocardiogram signal, blood oxygen saturation, blood pressure value, heart rate, body temperature, and the like. The measurement unit 310 sends the detected biological information to the transmission unit 340.

If the measurement unit 310 is detached from the patient's body, the biological information cannot be acquired appropriately. For this reason, the technical alarm detection unit 320 constantly checks whether or not the patient is not detached from the patient's body. For example, the technical alarm detection unit 320 detects that the measurement unit 310 is detached from the patient's body by supplying a weak current to the measurement unit 310 attached to the patient and monitoring a change in the current value. When it is detected that the measurement unit 310 is detached from the patient, the technical alarm detection unit 320 generates technical alarm information. Here, the technical alarm information is information indicating that a technical abnormality such as the sensor being detached from the patient has occurred. For example, the technical alarm information related to the ECG electrode includes “electrode confirmation” indicating that the ECG electrode is disconnected. The technical alarm information related to the SpO ₂ probe includes “probe confirmation” indicating that the SpO ₂ probe has been disconnected, “pulse wave detection impossible” indicating that the pulse wave cannot be detected from the acquired data, external light There is “external light noise” or the like that indicates noise contamination.

  The technical alarm detection unit 320 sends technical alarm information to the transmission unit 340.

  The identification information receiving unit 330 receives the identification information transmitted from the mobile terminal 200 when the transmitter 300 can communicate with the mobile terminal 200. For example, when the mobile terminal 200 communicates using a radio signal having a range of 1 m, if the mobile terminal 200 is within a distance of 1 m from the transmitter 300, the transmitter 300 can receive identification information from the mobile terminal 200. . That is, if the distance between the medical staff carrying the portable terminal 200 and the patient wearing the transmitter 300 is within 1 m, the transmitter 300 can receive the identification information from the portable terminal 200. The identification information receiving unit 330 sends the received identification information to the transmission unit 340.

  The transmission unit 340 transmits the biological information acquired from the measurement unit 310 to the receiver 400. Further, when the technical alarm information is acquired from the technical alarm detection unit 320, the transmission unit 340 transmits the acquired technical alarm information to the receiver 400. In addition, when acquiring the identification information from the identification information receiving unit 330, the transmission unit 340 transmits the acquired identification information to the receiver 400.

  The receiver 400 includes a receiving unit 410, a display unit 420, a notification unit 430, and a control unit 440.

  The receiving unit 410 receives biological information transmitted from the transmitter 300. In addition, when technical alarm information or identification information is transmitted from the transmitter 300, the receiving unit 410 receives the information.

  The display unit 420 is a display screen such as a liquid crystal display and displays various types of information such as biological information received by the receiving unit 410, a patient name, and a bed number.

  The notification unit 430 is a buzzer or a speaker, for example, and generates an alarm sound, an operation sound, or the like.

  The control unit 440 is, for example, a CPU, and performs control of each unit and various arithmetic processes. The control unit 440 includes a storage unit (not shown) that stores a program for control and various data.

  Next, processing in the medical system according to the first embodiment will be described.

  FIG. 3 is a flowchart illustrating processing executed by the receiver according to the first embodiment. FIG. 4 is a diagram showing the generation of the alarm shown in step S103 of FIG. FIG. 5 is a diagram showing alarm suppression shown in step S104 of FIG. 3 is stored in the storage unit of the receiver 400 as a program, and is executed by the control unit 440 controlling each unit.

  As shown in FIG. 3, the receiver 400 determines whether or not technical alarm information is received from the transmitter 300 (step S101). Here, the technical alarm information is generated by the technical alarm detection unit 320 of the transmitter 300 and transmitted to the receiver 400 by the transmission unit 340.

  When the technical alarm information is not received (step S101: NO), the receiver 400 repeats the process of step S101 until the technical alarm information is received.

  When the technical alarm information is received (step S101: YES), the receiver 400 determines whether or not the identification information is received from the transmitter 300 (step S102). Here, the identification information is acquired in advance from the portable terminal 200 by the identification information receiving unit 330 of the transmitter 300 and transmitted to the receiver 400 by the transmitting unit 340.

  When the identification information is not received (step S102: NO), the receiver 400 determines that there is no medical staff near the patient, and generates an alarm to notify that the medical staff needs to take action (step S103). ). For example, as shown in FIG. 4, when the patient's ECG electrode is disconnected, the transmitter 300 transmits technical alarm information indicating “electrode confirmation” of the ECG electrode. In this case, the receiver 400 generates an alarm by displaying a message “ECG electrode confirmation” on the display unit 420 or by sounding a warning sound by the notification unit 430. Thereby, the medical staff in the nurse station or the like can detect that an abnormality has occurred in the device for measuring the patient's condition and can take necessary measures.

  On the other hand, when the identification information is received (step S102: YES), the receiver 400 determines that there is a medical staff near the patient, and suppresses the alarm (step S104). For example, as shown in FIG. 5, when the ECG electrode is exchanged by the nurse N1, the transmitter 300 transmits the technical alarm information indicating “electrode confirmation” of the ECG electrode and the portable terminal 200 of the nurse N1. ID information of the nurse N1, which is identification information acquired from the above, is transmitted. In this case, the receiver 400 displays a message such as “Nursing N1 support” while displaying the message “ECG electrode confirmation” on the display unit 420. That is, the receiver 400 suppresses (mitigates) the alarm by adding a message “Nursing N1 is being supported”. Further, the alarm is suppressed so as not to generate an alarm sound by the notification unit 430. Thereby, the nurse N2 in the nurse station or the like can recognize that the nurse N1 is near the patient A in addition to the ECG electrode being detached from the body of the patient A. As a result, the nurse N2 is in a state where the ECG electrode is not removed due to replacement or maintenance, or the nurse N1 is already responding after the ECG electrode is removed due to an abnormality. It can be judged.

  As described above, according to the medical system of the first embodiment, when the receiver 400 receives the technical alarm information from the transmitter 300, if the identification information is received, the alarm is suppressed, and the identification information is received. Do not suppress the alarm if not received. As a result, even when the measurement unit 310 is detached from the patient's body, if the medical staff is near the patient, it is determined that the medical staff is replaced or maintained, and the alarm is suppressed. Therefore, an unnecessary alarm can be suppressed without a medical staff who performs replacement or maintenance of the measurement unit 310 manually performing an operation to suppress the alarm. Since unnecessary alarms are suppressed, the accuracy and reliability of alarms are improved, and medical staff can take appropriate measures according to the alarms.

  In addition, after the alarm suppression illustrated in step S104 of FIG. 3 is performed, when the receiver 400 cannot acquire the identification information while continuing to acquire the technical alarm information, the receiver 400 displays “ The message “Nursing N1 compatible” may be deleted. At that time, the receiver 400 may cause the alarm unit 430 to generate an alarm sound. As a result, the nurse N2 can recognize that the nurse N1 has moved away from the vicinity of the patient A while the ECG electrode remains detached from the patient A's body, and can take necessary measures.

  Moreover, although the said embodiment demonstrated as a thing which judges the presence or absence of reception of identification information, when the receiver 400 has received the technical alarm information, it is not limited to this. The receiver 400 determines whether or not the identification information is received even when the technical alarm is not received. When the identification information is received, the receiver 400 displays a message such as “Nursing N1 compatible”. May be. Thereby, the nurse N2 in a remote place such as a nurse station can recognize that the nurse N1 is near the patient A.

  In the above embodiment, the receiver 400 has been described as generating an alarm by the display unit 420 and the notification unit 430, but is not limited thereto. For example, an alarm may be generated by providing a light emitting unit in the receiver 400 to emit light. Alternatively, the receiver 400 may communicate with the portable terminal 200 carried by the medical staff via the network, and an alarm such as a message display may be generated in the portable terminal 200.

(Second Embodiment)
Next, the medical system of 2nd Embodiment is demonstrated.

  In the first embodiment, when the receiver 400 receives the identification information when receiving the technical alarm information, the alarm is suppressed regardless of the contents of the identification information. However, whether to suppress the alarm may be determined according to the content of the received identification information. In the second embodiment, a case will be described in which alarm suppression is performed only when the receiver 400 receives pre-registered identification information.

  The configuration of the medical system according to the second embodiment is the same as that of the first embodiment except for the configuration included in the receiver 400. In the following, description of portions overlapping with those of the first embodiment will be omitted, and description will be made focusing on portions different from those of the first embodiment.

  FIG. 6 is a block diagram illustrating a functional configuration of the medical system according to the second embodiment.

  As illustrated in FIG. 6, the receiver 400 includes a reception unit 410, a display unit 420, a notification unit 430, a control unit 440, and a registration unit 450. The configurations of the reception unit 410, the display unit 420, the notification unit 430, and the control unit 440 are the same as those in the first embodiment.

  The registration unit 450 receives the setting of arbitrary identification information from the user and registers the received identification information. In the registration unit 450, identification information set in the portable terminal 200 of a medical staff capable of handling a patient to which the transmitter 300 is attached is registered. For example, information indicating the identification ID of an individual medical staff, the ward, floor, medical department, etc. to which the medical staff belongs is registered in a portable terminal carried by the medical staff in charge of the patient. Registration unit 450 can register identification information for each transmitter 300 with respect to a plurality of transmitters 300. The registration unit 450 may be included in the control unit 440.

  Next, processing in the medical system according to the second embodiment will be described.

  FIG. 7 is a flowchart illustrating processing executed by the receiver according to the second embodiment. The process shown in the flowchart of FIG. 7 is stored as a program in the storage unit of the receiver 400, and is executed by the control unit 440 controlling each unit. Moreover, the process shown to step S101-step S104 of this flowchart is the same as the process shown to step S101-step S104 of FIG. Below, it demonstrates centering on the process shown to step S201.

  As shown in FIG. 7, the receiver 400 determines whether or not technical alarm information is received from the transmitter 300 in the process of step S101. When the technical alarm information is received (step S101: YES), the receiver 400 determines whether or not the identification information is received from the transmitter 300 in the process of step S102.

  When the identification information is not received (step S101: NO), the receiver 400 generates an alarm in the process of step S103 as in the first embodiment.

  When the identification information is received (step S102: YES), the receiver 400 determines whether or not the received identification information is registered (step S201). Specifically, receiver 400 refers to the content of identification information registered in advance in registration unit 450 and confirms whether or not the identification information received from transmitter 300 is registered.

  When the received identification information is not registered (step S201: NO), the receiver 400 determines that a medical staff close to the patient cannot handle the patient, and in the process of step S103, the first embodiment Generate an alarm in the same way as

  When the received identification information is registered (step S201: YES), the receiver 400 determines that a medical staff near the patient can handle the patient, and performs the first implementation in the process of step S104. Alarm suppression similar to the form is performed.

  As described above, according to the medical system of the second embodiment, the receiver 400 inquires whether the identification information received from the transmitter 300 is registered in the registration unit 450 in advance. If not registered, the alarm is not suppressed. Thereby, the alarm can be suppressed only when the identification information registered in advance is received, and the accuracy of the alarm can be improved. For example, even if there is a medical staff near the patient, if the medical staff cannot be handled by a medical staff from another department or building, an abnormality can be notified without suppressing the alarm.

  In the present embodiment, the receiver 400 has been described as suppressing the alarm when receiving the identification information registered in the registration unit 450 in advance, but the present invention is not limited to this. The receiver 400 may suppress an alarm when receiving information other than the identification information registered in the registration unit 450 in advance.
