Description

  The present invention relates to a subject management system, and more particularly to a subject management system that transmits data using an antenna.

  Various techniques for monitoring the condition of a subject in a hospital are known. As one of them, there is a technique in which a subject carries a medical transmitter (medical telemeter), measures the vital sign of the subject using the medical transmitter, and transmits the measured subject to a remote receiver (preferably a central monitor). The receiver displays the vital signs (waveforms and measured values) of the subject.

  The subject can move in the hospital while carrying the medical transmitter. The medical transmitter transmits various data to the receiver via a nearby antenna. For example, in a hospital, an antenna system that installs a plurality of whip antennas and transmits data received by the whip antenna is installed. Alternatively, an antenna system using a coaxial leakage cable may be installed in the hospital. In the antenna system, a coaxial leak cable is laid on the back of a ceiling of a hospital room or a corridor, and data transmitted from the medical transmitter is transferred to the receiver via the coaxial leak cable.

  The antenna system described above is a unidirectional system that transmits data from a medical transmitter to a receiver in principle. However, there are cases where it is desired to transmit various data from the receiver to the medical transmitter.

  Patent Document 1 discloses a system that newly secures a transmission channel from a receiver to a medical transmitter and transmits data from the receiver to the medical transmitter via the transmission channel (paragraph 0064 and the like).

“Wireless Sensor Network”, [online], [Search January 28, 2016], Internet <URL: http://www.linear-tech.co.jp/products/wireless_sensor_networks_-_dust_networks> “Dust Networks Wireless Sensor Network”, [online], [searched January 28, 2016], Internet <URL: http://3gsa.org/data/20140116Dust.pdf>

  As described above, it is assumed that the operation control data or the like is to be transmitted from the receiver to the medical transmitter. For example, there is a case where it is desired to instruct the start of measurement of vital signs from the receiver to the medical transmitter (for example, when it is desired to instruct the start of measurement of non-invasive blood pressure from a remote location). In addition to vital signs, various types of data (for example, notification of changes in settings of medical transmitters, identification data of medical transmitters, results of self-checks of medical transmitters, etc.) are transmitted from the medical transmitter to the receiver. There is also an increasing need. In other words, in addition to the need to perform two-way communication, there is also a need to handle a larger amount of data than is currently required (data that is not currently being transmitted is desired to be transmitted from the medical transmitter to the receiver). .

  The current antenna system mainly handles data having real-time characteristics (for example, an electrocardiogram waveform of a subject, a pulse wave waveform such as arterial oxygen saturation, an open blood pressure waveform, etc.). For this reason, a delay in data transmission and a failure in data transmission must be avoided. Because of this situation, it is difficult to handle a larger amount of data than at present because the occupied frequency band is expanded within a limited frequency band and the number of channels is decreased. In addition, since a general antenna system is unidirectional communication, data cannot be transmitted from the receiver to the medical transmitter.

  In the system of Patent Document 1 described above, a transmission channel and a reception channel are provided in the antenna system, and data is transmitted and received using each channel. However, in this system, since the amount of data handled in the antenna system becomes enormous, it is difficult to reliably transmit data having real-time characteristics.

  The present invention has been made in view of the above situation, and an antenna system that realizes bidirectional communication between a medical transmitter and a receiver without affecting an existing unidirectional antenna system. The main purpose is to provide.

One aspect of the antenna system according to the present invention is:
A medical transmitter for measuring a vital sign of a subject and transmitting first data, which may include measurement data of the vital sign, via an antenna system;
A receiver for receiving the first data via the antenna system;
A transmission / reception module for transmitting and receiving data via a network different from the antenna system,
The transceiver module receives the second data output from the receiver and transmits the second data to the medical transmitter, and receives third data from the medical transmitter and transmits the third data to the receiver.
Comprising
Subject management system.

  In the above-described configuration, the medical transmitter can transmit data (first data) that can include measurement data of vital signs to the receiver via the existing antenna system. The transmission / reception module enables bidirectional communication between the medical transmitter and the receiver via a network different from the antenna system. The medical transmitter and the receiver can transmit and receive data (second data and third data) using the transmission / reception module. Thereby, an increase in the amount of information handled by the antenna system can be avoided, and bidirectional communication between the medical transmitter and the receiver can be realized.

The present invention can provide an antenna system that realizes bidirectional communication between a medical transmitter and a receiver without affecting an existing unidirectional antenna system.

<Embodiment 1>
Embodiments of the present invention will be described below with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may differ from actual ratios.

  Prior to the description of the subject management system 1 according to the present embodiment, the configuration of a general subject management system 1 will be described. FIG. 1 is a conceptual diagram showing a configuration of a general subject management system 1. The subject management system 1 is mainly constructed in a hospital (regardless of size) and is an antenna system that transmits data using an antenna (such as a whip antenna or a coaxial leakage cable).

  The subject management system 1 includes a receiver 10, a power supply 20, an aggregator 30-1 to 30-6, amplifiers 40-1 to 40-40-3, and antennas 50-1 to 50-6. In the subject management system 1, a medical telemeter (medical transmitter) 60-1 carried by the patient is used. The number of each device used may be arbitrary and may be appropriately changed according to the in-hospital configuration. Elements having the same name but differing only in the number following the hyphen (“−”) basically have the same function and configuration. For example, the aggregator 30-1 and the aggregator 30-2 basically have the same functions and configurations. In the following description, when the description after the hyphen is omitted, it is assumed that the functions and configurations common to each device are described.

  The medical telemeter 60 is a device that measures a vital sign (specifically, an electrocardiogram waveform, blood pressure, body temperature, arterial oxygen saturation, etc.) of a subject. The medical telemeter 60 may be a bedside monitor, but is preferably a portable device. The medical telemeter 60 may be attached to a means fixed to the body such as a belt so that the subject can easily carry it. The medical telemeter 60 transmits data (hereinafter also referred to as biometric data) in which vital sign measurement data is associated with the subject's identifier and the like to the antenna 50 within the communication range. The biological data is transmitted to the receiver 10 via a cable line.

  The receiver 10 receives biometric data transmitted from the medical telemeter 60. The receiver 10 is preferably a central monitor, although not limited thereto. The receiver 10 receives biometric data from a plurality of medical telemeters 60 and displays the measured values and measurement waveforms of vital signs of a plurality of subjects on an attached display.

  The antennas 50 installed at a plurality of locations are converged by the aggregator 30. The antenna 50 covers a certain range in the hospital and receives biological data transmitted from the medical telemeter 60 within the covered range. The antenna 50 transmits the received biological data to the receiver 10 via the aggregator 30 and the amplifier 40.

  The aggregator 30 distributes cable lines connected to each device. That is, the collector 30 branches the electrical connection of the antenna system. The amplifier 40 (booster) amplifies the signal indicating the biological data transmitted from the antenna 50 and transmits the amplified signal toward the receiver 10. The amplifier 40 operates upon receiving power supply from the power supply machine 20.

  The power supply machine 20 is connected to a commercial power outlet in the hospital and supplies power to the amplifier 40. For example, the power supply machine 20 converts AC power (for example, 100V) supplied from a commercial power outlet into DC power (for example, 15V). Then, the power supply unit 20 supplies the DC power converted through the coaxial cable line to the amplifier 40.

  The connections of each device (antenna 50 to collector 30, cluster 30 to amplifier 40, collector 30 to receiver 10) are connected by, for example, a coaxial cable line. The coaxial cable line is configured to be able to supply power to each device with a DC power source. For example, a coaxial cable line is a cable configured to cover a core line with a ground line. The coaxial cable supplies DC power to each device connected by this duplex structure.

  In the subject management system 1, the transmission path of various data (including biological data) from the medical telemeter 60 to the receiver 10 is as follows. The medical telemeter 60 transmits data (signal) to the antenna 50 having a short physical distance. The antenna 50 supplies data (signal) to the amplifier 40 via the aggregator 30. The amplifier 40 amplifies the input data (signal) and transmits the data (signal) to the receiver 10.

  The biometric data transmission process will be described below using the medical telemeter 60-1 as an example. The medical telemeter 60-1 transmits biological data to the antenna 50-1. The antenna 50-1 transmits biological data to the amplifier 40-1 via the cable line and the collector 30-2. The amplifier 40-1 amplifies the biological data (signal) and transmits it to the receiver 10 via the cable line and the collector (30-3, 30-1). The receiver 10 displays various types of information (such as measured values and waveforms of vital signs) on the display screen based on the received biological data.

  The above is the configuration and operation concept of the general subject management system 1. Next, the configuration of the subject management system 1 according to the present embodiment will be described. FIG. 2 is a conceptual diagram showing a configuration of the subject management system 1 according to the present embodiment. The subject management system 1 according to the present embodiment is provided with transmission / reception modules 70-1 to 70-5 in addition to the configuration of FIG. An arbitrary number of transmitting / receiving modules 70 may be arranged.

  The transmission / reception module 70 transmits / receives data via a network different from the antenna system (a network system including the antenna 50 and a coaxial cable). For example, the transmission / reception module 70 implements data transmission / reception between the medical telemeter 60 and the receiver 10 by applying wireless sensor network technology.

  Although the transmission / reception module 70 does not ask | require a connection form etc., it should just transmit data applying the technique of a wireless sensor network. The concept of the wireless sensor network will be described with reference to FIG.

  FIG. 3 is a diagram illustrating the concept of the wireless sensor network 100 constructed by the transmission / reception module 70. The wireless sensor network 100 is an independent network from the antenna system (network connected by a cable line) shown in FIG. 2 from the viewpoint of data transmission / reception. The wireless sensor network 100 only needs to be configured based on, for example, the 6LoWPAN standard and the 802.15.4e standard (Non-Patent Document 1, Non-Patent Document 2, etc.). The wireless sensor network 100 may be a network that uses, for example, TSMP (Time Synchronized Mesh Protocol) and adopts a mesh type topology.

  The wireless sensor network 100 includes a receiver 10, transmission / reception modules 70-1 to 70-8, a manager terminal 71, and medical telemeters 60-1 to 60-3. The number of transmission / reception modules 70 and medical telemeters 60 may be arbitrary. The wireless sensor network 100 is used for data transmission / reception between the receiver 10 and the medical telemeters 60-1 to 60-3.

  The receiver 10 manages information such as used channels, serial numbers, and MAC addresses of the medical telemeters 60-1 to 60-3. That is, the receiver 10 manages the identification information of the medical telemeter 60 connected to the wireless sensor network 100. The medical telemeter 60 transmits its own identification information to the receiver 10 via the antenna system and the wireless sensor network 100 at the start of use.

  In the wireless sensor network 100, data transmission is performed between each medical telemeter 60 and the receiver 10, and data transmission is not performed between the medical telemeters 60. Therefore, the wireless sensor network 100 can also be interpreted as a tree structure with the receiver 10 as a root node. Therefore, when each medical telemeter 60 or the transmission / reception module 70 recognizes the route node direction (data transmission direction to the receiver 10) when participating in the network, data transmission from the medical telemeter 60 to the receiver 10 is realized. .

  The manager terminal 71 is a device that manages connection information of the wireless sensor network 100. An example of connection information managed by the manager terminal 71 is shown in FIG. The manager terminal 71 manages the connection relationship of each transmission / reception module 70 as shown in FIG. The medical telemeter 60 has a transmission / reception function equivalent to that of the transmission / reception module 70 installed therein. Therefore, the manager terminal 71 manages the connection information on the assumption that the medical telemeter 60 is also a kind of the transmission / reception module 70.

  When a new transmission / reception module 70 participates in the wireless sensor network 100, a participation request is transmitted to the manager terminal 71 via the transmission / reception module 70 arranged in the immediate vicinity of the new transmission / reception module 70. The manager terminal 71 updates the connection information (FIG. 4) in response to the participation request. Further, the manager terminal 71 may notify a newly participating transmission / reception module 70 of a route to the manager terminal 71.

  When the medical telemeter 60 moves, the medical telemeter 60 transmits a connection destination update request to the manager terminal 71. The manager terminal 71 updates the connection information (FIG. 4) in response to the update request.

  The receiver 10 transmits data to be transmitted and identification information of the medical telemeter 60 managed by the receiver 10 to the manager terminal 71. The manager terminal 71 determines a transmission path based on the identification information and the connection information (FIG. 4), and transmits the transmission path information and data to be transmitted to the transmission / reception module 70 on the transmission path. The transmission / reception module 70 that has received the data transfers the data to the medical telemeter 60 as the destination according to the transmission path information.

  Note that the above-described communication method is merely an example, and the transmission / reception module 70 may apply communication using an arbitrary sensor network without an antenna. In the example of FIG. 3, the receiver 10 and the manager terminal 71 are directly connected. However, the configuration is not limited to this, and the receiver 10 and the manager terminal 71 may not be directly connected.

  Next, the flow of data and power supply in the subject management system 1 will be described with reference to FIG. For simplification of description, the description of the manager terminal 71 is omitted in FIG.

  The medical telemeter 60 transmits data (first data) to the receiver 10 using an existing antenna system. Here, the medical telemeter 60 is biometric data that requires real-time properties via an antenna system (for example, measurement data of a vital sign of a subject, and is preferably data that is processed and displayed without delay. It is desirable to transmit the requested data (also referred to as real-time data in FIG. 5). For example, the medical telemeter 60-1 transmits biological data to the receiver 10 via the cable line via the antenna 50-1, the collector 30-2, the amplifier 40-1, the collector 30-3, and the collector 30-1. (Dash-dot line in FIG. 5).

  As described above, when the medical telemeter 60 transmits the biological data via the antenna system, the existing antenna system can be used without changing the application of the existing antenna system or the amount of data to be handled.

  The receiver 10 transmits data (second data) to the medical telemeter 60 via the transmission / reception module 70. For example, the receiver 10 transmits information (also referred to as operation control information) instructing operation control of the medical telemeter 60 (for example, measurement start instruction of various vital signs) (two-dot chain line in FIG. 5). For example, the receiver 10 transmits operation control information for instructing the medical telemeter 60-1 to start non-invasive blood pressure measurement via the transmission / reception modules 70-1, 70-2, and 70-3. When receiving a non-invasive blood pressure measurement instruction, the medical telemeter 60-1 starts pressurization with a cuff (not shown) and performs measurement. Prior to the start of measurement, the medical telemeter 60-1 may make a voice announcement such as “start blood pressure measurement according to an instruction from the receiver 10 (medical worker)”.

  The medical telemeter 60 transmits data (third data) to the receiver 10 via the transmission / reception module 70. Here, the content of the data (third data) transmitted from the medical telemeter 60 via the transmission / reception module 70 is not particularly limited, but is preferably data that does not require real-time property (non-real-time data). That is, it is preferable that data requiring real-time property is transmitted via the antenna system, and data not requiring real-time property is transmitted via the transmission / reception module 70. Thereby, bidirectional data transmission can be performed without changing the application of the existing antenna system.

  For example, the medical telemeter 60-1 transmits device management information to the receiver 10 via the transmission / reception modules 70-3, 70-2, and 70-1 (two-dot chain line in FIG. 5). The device management information is information that can include the remaining battery level of the medical telemeter 60-1 and the result of self-check. The medical telemeter 60-1 transmits device management information to the receiver 10 at a predetermined time (for example, every 12 hours). The receiver 10 determines whether or not the medical telemeter 60-1 is in good condition based on the device management information (for example, whether or not the remaining battery level is 30% or more), and outputs an alarm if there is a problem. Etc.

  Next, the flow of power supply will be described. As described above, data transmission via the antenna system (antenna 50 or cable line) and data transmission / reception via the transmission / reception module 70 operate independently. However, the transmission / reception module 70 is configured to be connected to the cable line of the antenna system. For example, the transmission / reception module 70-2 is connected to a cable line in the antenna system, and is connected to the collector 30-7 via the cable line. After performing the AC / DC power conversion as described above, the power supply unit 20 supplies the DC power to the amplifier 40 via the cable line (power is supplied by superimposing the DC power on the cable line). Using this mechanism, the transmission / reception module 70 supplies DC power via a cable line. For example, the transmission / reception module 70-2 receives the DC power supplied from the power supply machine 20 via a cable line extending from the collector 30-7 (dotted line in FIG. 5). The transceiver module 70-2 is driven by the received DC power source. That is, the transmission / reception module 70-2 can be driven without being connected to a battery or a commercial outlet.

  The transmission / reception module 70 can be connected to a commercial outlet or can be battery driven. However, it is preferable that the transmission / reception module 70 receives power from the power supply unit 20 in order to avoid the problem of installation location and battery exhaustion. The power supply machine 20 is connected to an uninterruptible power supply (not shown) of hospital equipment as a commercial outlet in the hospital. It is important to know the patient's life status in the event of an emergency such as an earthquake disaster, and prevent the entire system from shutting down when the hospital loses power. By connecting in this way, the power source can be centrally managed and operated safely.

  Next, effects of the subject management system 1 according to the present embodiment will be described. The medical telemeter 60 can transmit data (first data) that can include measurement data of vital signs to the receiver 10 via an existing antenna system. The transmission / reception module 70 enables bidirectional communication between the medical telemeter 60 and the receiver 10 via a network different from the antenna system. The medical telemeter 60 and the receiver 10 can transmit and receive data (second data and third data) using the transmission / reception module 70. Thereby, a large increase in the amount of data handled by the antenna system can be avoided, and bidirectional communication between the medical telemeter 60 and the receiver 10 can be realized.

  The transmission / reception module 70 is physically connected to the cable line of the antenna system. The power supply unit 20 in the antenna system may be configured to supply power to the amplifier 40 and the transmission / reception module 70 via a cable line. Thereby, the power supply of the transmission / reception module 70 can be performed only by connecting the transmission / reception module 70 to the cable line of the existing antenna system.

  Further, the receiver 10 can transmit operation control information for instructing the medical telemeter 60 to perform operation control (for example, information for instructing start of noninvasive blood pressure measurement). The medical telemeter 60 performs processing (for example, start of noninvasive blood pressure measurement) according to the operation control information. Thereby, the medical worker can perform an appropriate measurement process on the subject while being at a remote place.

  The medical telemeter 60 transmits device management information via the transmission / reception module 70. That is, the medical telemeter 60 notifies the receiver 10 of its own state (remaining battery level, presence / absence of error due to self-check, etc.). The receiver 10 may display information about the medical telemeter 60 that is in error (or has a high probability of error). Thereby, the medical worker can recognize the abnormality of the medical telemeter 60 while being at a remote place, and can take prompt action.

  In addition, although the antenna 50 which comprises the above-mentioned test subject management system 1 was what is called a whip antenna, it is not necessarily restricted to this, The system using a coaxial leaky cable may be sufficient. FIG. 6 is a block diagram showing a configuration of the subject management system 1 using the coaxial leakage cable 51. The coaxial leakage cable 51 is laid on the ceiling behind the hospital. The coaxial leakage cable 51 is stretched around the hospital while being connected to the receiver 10 and the amplifier 40. The coaxial leakage cable 51 has a property that radio waves leak out with signal transmission. Therefore, the coaxial leaky cable 51 is a coaxial cable having the same effect as the antenna 50 (in other words, the coaxial leaky cable 51 can be considered as a kind of antenna integrated with the cable). In FIG. 6, the data flow using the coaxial leaky cable 51 is indicated by a one-dot chain line. The medical telemeter 60 transmits data to the coaxial leak cable 51. The coaxial leakage cable 51 transmits the received data. Other configurations are the same as those in FIG. Even in the existing antenna system using the coaxial leakage cable 51, two-way communication can be easily realized by simply connecting the transmission / reception module 70 to the branch destination by the collector 30 as in the configuration of FIG. .

<Embodiment 2>
The subject management system 1 according to the present embodiment is further connected to an electronic medical record system 200. In the following description, a processing unit having the same name and reference numeral as in the first embodiment is assumed to have the same configuration as in the first embodiment unless otherwise described (the same applies to the following embodiments). ).

  FIG. 7 is a block diagram showing a configuration of the subject management system 1 according to the present embodiment. The subject management system 1 further includes a vital sign measurement terminal 72 in addition to the configuration of FIG. The receiver 10 is connected (linked) with the electronic medical chart system 200.

  The vital sign measurement terminal 72 is a terminal that measures a subject's vital sign in a spot manner (intermittently). In the ward, not all subjects (patients) carry the medical telemeter 60, and some subjects do not carry the medical telemeter 60 depending on the pathological condition. For these subjects, various vital signs (for example, body temperature, blood pressure, arterial oxygen saturation) may be desired. The vital sign measurement terminal 72 is a terminal that measures the vital sign of such a subject in a spot manner.

  A subject who does not carry the medical telemeter 60 may carry a wristband or the like in which a code associated with a name or the like is embedded in an arm or the like. The vital sign measurement terminal 72 is connected to a reader that reads a code carried by the subject. The vital sign measurement terminal 72 reads the code carried by the subject and transmits it to the receiver 10. The vital sign measurement terminal 72 transmits and receives data via the transmission / reception module 70 in the same manner as the medical telemeter 60.

  The vital sign measurement terminal 72 is configured to be connectable with a probe for measuring various vital signs. The vital sign measurement terminal 72 may be configured to be connectable to various sensors (for example, a thermometer) via short-range wireless communication (Bluetooth: registered trademark). The vital sign measurement terminal 72 calculates vital sign measurement data from the biological signal acquired through the probe.

  The electronic medical record system 200 is a system for integrated management of recording of medical practice, recording of measurement data of various vital signs, and the like. The electronic medical record system 200 manages the identification information of the subject in association with the medical practice and vital sign measurement data.

  Hereinafter, a usage scenario example of the subject management system 1 shown in FIG. 7 will be described.

  The subject causes the reader of the vital sign measurement terminal 72 to read the wristband code (identifier). The vital sign measurement terminal 72 transmits the identifier read via the transmission / reception modules 70-2 and 70-1 to the receiver 10. The receiver 10 transmits the identifier to the electronic medical chart system 200. The receiver 10 and the electronic medical chart system 200 may be connected by an arbitrary connection form (for example, LAN).

  The electronic medical record system 200 reads the subject information based on the identifier, and transmits the read subject information (the subject's name, sex, age, previous vital sign measurement values, etc.) to the receiver 10. The receiver 10 transmits the subject information to the vital sign measurement terminal 72 via the transmission / reception modules 70-1 and 70-2.

  The vital sign measurement terminal 72 displays the received subject information on the display. As a result, the subject can measure his / her own data or grasp the previous measurement value.

  The vital sign measurement terminal 72 measures an arbitrary vital sign (for example, blood pressure or arterial oxygen saturation) of the subject. The vital sign measurement terminal 72 transmits the vital sign measurement result to the receiver 10 via the transmission / reception modules 70-2 and 70-1. The receiver 10 transmits the received measurement result to the electronic medical chart system 200.

  The electronic medical record system 200 registers the received measurement result in association with the subject identifier. The electronic medical record system 200 notifies the receiver 10 that registration (update) has been completed. The receiver 10 notifies the vital sign measurement terminal 72 that the registration is completed via the transmission / reception modules 70-1 and 70-2.

  The vital sign measurement terminal 72 displays on the display that registration has been completed. Thus, the subject can grasp that the measurement has been completed successfully.

  In this way, the vital sign measurement terminal 72 measures the vital sign of the subject in a spot manner, and transmits the vital sign measurement data to the receiver 10 (and thus the electronic medical chart system 200) via the transmission / reception module 70. That is, it is possible to realize spot vital sign measurement results without increasing the amount of data handled by the antenna system.

  Further, when the receiver 10 is connected to the electronic medical record system 200, the electronic medical record system 200 can manage the vital sign measurement of the subject in a unified manner.

  In addition, bidirectional communication is realized between the electronic medical record system 200 and the vital sign measurement terminal 72. Thus, the subject can recognize information transmitted from the electronic medical chart system 200 (for example, registration is completed). The subject can use the system with confidence by referring to the registration completion notification.

<Embodiment 3>
The subject management system 1 according to the present embodiment is characterized in that data can be transmitted from the receiver 10 to a device other than the medical telemeter 60 via the transmission / reception module 70. Hereinafter, the subject management system 1 according to the present embodiment will be described while referring to differences from the first embodiment.

  FIG. 8 is a block diagram showing an operation concept of the subject management system 1 according to the present embodiment. In the subject management system 1 according to the present embodiment, it is assumed that a medical worker carries the mobile terminal 80. Similar to the medical telemeter 60, the portable terminal 80 has a function (module) for transmitting / receiving data via the transmission / reception module 70.

  The medical telemeter 60 transmits biological data via the antenna system as in the first embodiment. The receiver 10 analyzes the received biological data.

  The receiver 10 transmits data on the subject toward the portable terminal 80 when the predetermined condition is satisfied. Here, the predetermined condition defines conditions under which it is better to notify the medical staff of data indicating the state of the subject (hereinafter also referred to as subject state information). For example, the predetermined conditions include “when an abnormality is detected when analyzing the biological information (measured value or measured waveform of vital sign) of the subject (for example, when an alarm state occurs)”, “notifying the subject's state "When a certain time has elapsed since the last notification (when a certain time has elapsed since the previous notification)", "When a predetermined time has come", and the like. These predetermined conditions may be appropriately set by medical personnel.

  The receiver 10 transmits subject state information to the portable terminal 80 via the transmission / reception module 70 when the predetermined condition is satisfied. The subject state information may be a measured value of the subject's vital sign or the measurement waveform itself, or may be information related to the detected alarm state (for example, a message such as “Mr. A is arrhythmia”). Good.

  FIG. 9 is a conceptual diagram showing a usage image of the mobile terminal 80. The portable terminal 80 displays the subject state information transmitted from the receiver 10. The subject state information displayed here may be an alarm message such as “Mr. A's arrhythmia” as shown in the figure, and various vital signs (blood pressure, heart rate, arterial oxygen saturation, respiratory rate, etc.) of the subject. A measurement value or a measurement waveform may be displayed. When displaying an alarm message, the portable terminal 80 may output an alarm sound together.

  The medical staff can grasp the state of the subject by referring to the portable terminal 80 even when the medical worker is in a remote place. Accordingly, the medical staff can recognize that the condition of the subject has suddenly changed even when he is in a remote place.

  The receiver 10 also transmits an identification code (for example, an identification code of a symbol as shown) for accessing various types of information (mainly measured values and measurement waveforms of the vital sign) of the subject to the portable terminal 80. Also good. The portable terminal 80 displays the received identification code on the display screen as illustrated.

  A plurality of display devices 90 (not shown in FIG. 8) are arranged in the hospital. The display device 90 is a device connected to the receiver 10 via a network (for example, a LAN (Local Area Network)). The display device 90 is connected (or integrated) with a reading unit 91 that reads an identification code. The reading unit 91 is a bar code reader, a QR code reader, or the like. The medical staff causes the reading unit 91 of the display device 90 to read the identification code.

  The display device 90 transmits the read identification code to the receiver 10 via the network. The receiver 10 transmits various types of information (subject name, age, sex, measured value of vital signs, measured waveform of vital signs, etc.) corresponding to the identification code to the display device 90. The display device 90 displays the received various information about the subject on the display. The display device 90 may perform display in the same form as, for example, a general central monitor or bedside monitor.

  The medical staff can grasp the detailed information of the subject by referring to the display screen (FIG. 9). A plurality of display devices 90 are preferably installed in the hospital. Accordingly, the medical staff can quickly recognize the state of the subject from the nearby display device 90 even when the subject's room is far away.

  In FIG. 9, the portable terminal 80 is assumed to be a wristband type device, but is not limited to this. The portable terminal 80 may be any device that can be carried by a medical worker.

  Next, effects of the subject management system 1 according to the present embodiment will be described. The receiver 10 notifies the subject state information to the portable terminal 80 carried by the medical staff when a condition (predetermined condition) that is better to notify the subject's state is satisfied. For example, when the subject has an arrhythmia, the receiver 10 transmits subject state information such as “Mr. A's arrhythmia” to the portable terminal 80. As a result, the medical staff can accurately grasp the abnormality or the like of the subject even in a remote place. In addition, since the receiver 10 transmits the subject state information via the transmission / reception module 70, the receiver 10 can perform notification without increasing the information amount of the antenna system.

  The predetermined condition that defines the timing of notification includes a case where the subject is in an alarm state, a predetermined time is reached, and a predetermined time has elapsed since the previous notification. When notifying when an alarm state occurs, the medical staff can grasp the abnormality of the subject even in a remote place. In addition, when a notification is given when a predetermined time or a predetermined time elapses, a medical worker can periodically check the condition of the subject even in a remote place.

  As shown in FIG. 9, the subject state information may include an identification code that can access the vital sign of the subject. The medical staff can display the vital sign of the subject on the display device 90 by using this identification code. Thereby, the medical staff can confirm the measured value and measurement waveform of the subject's vital signs on a large screen.

  In addition, when transmitting the subject state information in response to the abnormality detection, the receiver 10 may transmit the subject state information after specifying the terminal of the medical worker in charge of the subject. In this case, the receiver 10 may manage the correspondence between the medical staff and the subject in advance. For example, the receiver 10 may manage a relationship in which the subject A and the medical worker X are associated with each other.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the embodiments already described, and various modifications can be made without departing from the scope of the invention. It goes without saying that it is possible.
