An embodiment of the present disclosure will be described below by way of example with reference to the drawings. Identical or equivalent elements will be designated by the same reference signs or names correspondingly and respectively even in different drawings, and duplicate description thereof will be therefore omitted appropriately.
First, a configuration of a system 400 according to the embodiment of the present disclosure will be described using
In the system 400, the portable information terminal 100 detects, of the AEDs 1, an AED 1 in an activated state, and transmits notification information for notification about the activation of the AED 1 to the management computer 200. In addition, the management computer 200 transmits predetermined information to the computer apparatus 300 as occasion demands. The respective apparatuses that may be included in the system 400 and respective processors constituting the apparatuses will be described below in detail.
AED
Each of the AEDs 1 is provided with a controller 10, a memory 20, an operation accepter 30, a display unit 40, a sounder 50, a high voltage generator 60, a pad connector 70, a power supply 80, and a wireless communicator 90. The AED 1 may be a portable type AED or may be a stationary type AED. Incidentally, it is preferable that the AED 1 is not provided with a GPS sensor.
The controller 10 reads and executes a program etc. stored in the memory 20 to control various actions of the AED 1. The controller 10 has a processor such as a CPU (Central Processing Unit), a memory such as an ROM (Read Only Memory) or an RAM (Random Access Memory), an A/D converter, etc.
The controller 10 controls various actions for life rescue such as energy charging/discharging control, sequence control, A/D conversion, and electrocardiogram analysis. In addition, the controller 10 controls execution of a self-test of the AED 1. In the self-test, for example, the controller 10 checks states of a circuit for controlling the life rescue actions, the power supply 80, a defibrillation pad (not illustrated) connected to the pad connector 70, etc. to confirm whether they are normal or abnormal.
Further, the controller 10 may function as a wireless communication module. The controller 10, for example, performs transmission/reception of information to/from another apparatus such as the portable information terminal 100 through the wireless communicator 90.
At a predetermined timing such as after a series of the life rescue actions has been completed or after the self-test has been terminated, the controller 10 may transmit, to the portable information terminal 100 or another computer or the like, physiological information such as electrocardiogram data of a person in need for rescue, to whom the life rescue actions have been applied, or a result of the self-test.
The memory 20 stores a program necessary for the AED 1 to act, audio data, an adjustment value, the electrocardiogram data during the life rescue, the result of the self-test, etc. The memory 20 may include, for example, a secondary memory device such as a hard disk. A part of the memory 20 may be an external memory device that can be detachably attached to the AED 1.
The operation accepter 30 accepts an operation input from a user of the AED 1. The operation accepter 30 may include a power button for activating the AED 1, a check button for starting the self-test, a shock button for executing an electric shock, etc. Incidentally, for example, through the power button or the check button pressed down in a state in which the AED 1 is powered off or through a cover of the AED 1 turned into an open state, the AED 1 is brought into an activated state. The activated state means a state in which the AED 1 is capable of executing processings for life rescue (such as outputting of voice guidance, detection of attachment of the defibrillation pad, detection of an electrocardiogram, outputting of defibrillation shock energy, etc.).
The display unit 40 may include an indicator for displaying the result of the self-test, a liquid crystal display for displaying an instruction to the user of the AED 1 as a figure or characters, a display for displaying an electrocardiogram signal, etc. In addition, the display unit 40 may be provided with a touch panel or may function also as the operation accepter 30.
The sounder 50 issues various instructions to the user of the AED 1 by voice with reference to the audio data stored in the memory 20. In addition, when an abnormality has been found by the self-test, the sounder 50 emits a warning sound to notify the user of the abnormality.
The high voltage generator 60 carries out charging and discharging of energy used for defibrillation in accordance with a control signal from the controller 10. The pad connector 70 is connected to the defibrillation pad. The energy discharged by the high voltage generator 60 is transmitted to the person in need for rescue through the pad connector 70 and the defibrillation pad. In addition, the defibrillation pad fetches an electrocardiogram signal of the person in need for rescue. The electrocardiogram signal is, for example, filtered and amplified before being transmitted to the controller 10.
The power supply 80 includes a battery. The power supply 80 converts electric power supplied from the battery into a required voltage, and supplies the electric power to the aforementioned processors.
The wireless communicator 90 is an interface that enables wireless communication with another apparatus such as the portable information terminal 100. When the AED 1 is brought into the activated state, a wireless signal is sent from the wireless communicator 90 toward the outside. Here, the “wireless signal” means, for example, an audio signal such as a DTMF (Dual Tone Multi Frequency) signal, an optical signal such as an infrared beacon, or a radio signal such as a radio beacon. Incidentally, when the wireless signal is the audio signal, the sounder 50 may function as the wireless communicator 90.
It is preferable that, for example, first identification information by which the AED 1 can be identified individually is included in the wireless signal. In addition, it is preferable that the wireless signal is the radio signal. It is preferable that the wireless communicator 90 is compatible with a radio communication standard such as a wireless LAN (Local Area Network) standard or a Bluetooth (registered trademark) standard. In this case, the wireless communicator 90 forms a part of a wireless LAN module, a Bluetooth module, or the like. Thus, a network identifier such as an SSID (Service Set Identifier) by which the AED 1 can be identified individually, or the radio beacon including the first identification information such as an identifier of the AED 1 is sent as the wireless signal from the wireless communicator 90.

The communicator 190 is an interface that enables communication with another apparatus. The communicator 190 is an interface that can be compatible with a standard of the wireless signal sent from the AED 1. In addition, the communicator 190 enables communication with the management computer 200 through a communication network.
Various actions of the controller 110 will be described below in detail. The controller 110 reads and executes the program 121 to function as a registerer 111, a detector 112, an acquirer 113, and a transmitter/receiver 114.
The registerer 111 stores, as the registration information 122 in the memory 120, second identification information for individually identifying the AED 1 set as a detection target. The second identification information is information identical to or corresponding to the aforementioned first identification information. In addition, the registerer 111 may store, as the registration information 122 in the memory 120, individual information of the AED 1 set as the detection target, individual information of the portable information terminal 100, and individual information of the user of the portable information terminal 100. Here, the “individual information” means, for example, a model number, a terminal identification number or personal information of the user of the portable information terminal 100.
The detector 112 detects presence/absence of the AED 1 in the activated state, based on presence/absence of the aforementioned wireless signal that can be detected according to the fact that the AED 1 has been activated. Upon detection of the aforementioned wireless signal, the detector 112 determines that the AED 1 in the activated state is present.
When the wireless communicator 90 corresponds to the wireless LAN module, the detector 112 detects the SSID etc. included in the radio beacon sent from the wireless communicator 90. When the wireless communicator 90 corresponds to the Bluetooth module, the detector 112 detects the identifier etc. of the AED 1 included in the radio beacon sent from the wireless communicator 90. Moreover, when the wireless signal is an audio signal or an optical signal, the detector 112 detects presence/absence of a specific signal that has been set in advance.
The detector 112 can detect only the specific AED 1 by collating the detected first identification information with the second identification information registered in the registration information 122. It is preferable that a time interval at which the detector 112 executes a detection action can be set desirably by the user of the portable information terminal 100. The detector 112 detects presence/absence of the wireless signal at a predetermined time interval of, for example, thirty seconds, one minute, five minutes, ten minutes, or the like.
The acquirer 113 acquires the position information of the portable information terminal 100 when the AED 1 in the activated state has been detected by the detector 112. The position information is acquired by use of the GPS sensor or the like included in the sensor unit 150. In addition, the acquirer 113 may acquire the individual information stored in the registration information 122 when the AED 1 in the activated state has been detected by the detector 112.
The transmitter/receiver 114 performs transmission/reception of information to/from another apparatus. The transmitter/receiver 114 receives the aforementioned wireless signal from the AED 1 through the communicator 190. In addition, the transmitter/receiver 114 may receive physiological information such as electrocardiogram data of a person in need for rescue, or a result of a self-test.
In addition, the transmitter/receiver 114 transmits, to the management computer 200, notification information for notification about the activation of the AED 1 when the AED 1 in the activated state has been detected by the detector 112. The position information and/or the individual information which has been acquired by the acquirer 113 may be included in the notification information.

An action example of the system 400 will be described below.
A user of the system 400 is not limited particularly. However, description will be made below in a case where an administrator of a sporting event is the user of the system 400 by way of example. In the present example, the management computer 200 may be installed in an emergency head office or the like of the sporting event. In addition, the user of the portable information terminal 100 is an emergency staff placed at any place in the sporting event. The portable information terminal 100 may be a smartphone carried by the emergency staff. In addition, some emergency staffs carrying the portable type AEDs 1 may be users U of the AEDs 1. One of the users U of the AEDs 1 and the user of the portable information terminal 100 may be the same person.
In the example of
In the example of
A range in which the AEDs 1 can be detected by the portable information terminal 100 is a range where a wireless signal sent from each of the AEDs 1 can reach. When the wireless signal is a radio beacon based on a wireless LAN, the range in which the wireless signal can reach is, for example, a circle with a radius of about 100 m from the AED 1. In addition, when the wireless signal is a radio beacon based on Bluetooth, the range in which the wireless signal can reach is, for example, a circle with a radius of about 10 m from the AED 1.
In the example of
The AEDs 1B to 1D are also present in the range where the portable information terminal 100 can detect the wireless signal. However, since the AEDs 1B to 1D are not activated and do not send wireless signals, the AEDs 1B to 1D are not detected. In addition, assume that the portable information terminal 100 is set so as to detect only a specific AED 1 corresponding to second identification information that has been registered in the registration information 122, and the AEDs 1B to 1D are not set as detection targets. In this case, the portable information terminal 100 does not detect activation of the AEDs 1B to 1D even if the AEDs 1B to 1D have been activated.
Upon detection of the activation of the AED 1A, the portable information terminal 100 acquires position information of the portable information terminal 100 by use of the GPS sensor provided in the portable information terminal 100. In addition, the portable information terminal 100 transmits notification information including the position information to the management computer 200.
The management computer 200 receives the notification information. Upon reception of the notification information, the management computer 200 may notify a staff or the like in the emergency head office or the like of the fact that the notification information has been received. In addition, in accordance with an operation input or the like of the staff, a position 242 indicated by the position information included in the notification information, and a map 241 around the position 242 are displayed on the display unit 240. The management computer 200 transmits the notification information for notification about the activation of the AED 1A or the aforementioned position information to the computer apparatus 300 as occasion demands.
In addition, at a predetermined timing after the AED 1A has completed the series of life rescue actions, the AED 1A transmits physiological information such as electrocardiogram data of the person Pin need for rescue to the portable information terminal 100. The portable information terminal transmits the received physiological information to the management computer 200. In addition, the management computer 200 transmits the received physiological information to the computer apparatus 300 as occasion demands.
Next, action examples of the portable information terminal 100 and the management computer 200 in the system 400 will be described in detail by use of flowcharts.
First, the flowchart of
The portable information terminal 100 sets an interval for detecting a wireless signal of the AED 1 (step S102). In addition, in the step S102, a detection target or targets of the portable information terminal 100 may be set. Specifically, one or more AEDs 1 of the AEDs 1 corresponding to pieces of the second identification information or pieces of the individual information that have been registered in the registration information 122 may be set as the detection targets. Incidentally, when the detection targets are not set individually, all of the AEDs 1 which can be detected by the program 121 may be the detection targets.
The steps S101 and S102 may be executed based on an operation input of the user of the portable information terminal 100, for example, only when the user judges that the steps S101 and S102 are necessary.
The portable information terminal 100 detects presence/absence of the activated AED 1 based on presence/absence of the wireless signal sent by the activated AED 1 (step S103). When the activation of the AED 1 which is the detection target has not been detected (NO in a step S104), the step S103 is repeated at the time interval set in the step S102.
When the activation of the AED 1 which is the detection target has been detected (YES in the step S104), the portable information terminal 100 acquires predetermined information (step S105). The predetermined information acquired in the step S105 may be the position information of the portable information terminal 100, and/or the individual information etc. stored as the registration information 122. Incidentally, the step S105 is preferably executed. However, the step S105 is not essential action processing in the system 400.
The portable information terminal 100 transmits the notification information for notification about the activation of the AED 1 to the management computer (step S106). It is preferable that the position information, the individual information etc. acquired in the step S105 is included in the notification information.
Here, the communication connection between the portable information terminal 100 and the AED 1 is not established during execution of the steps S104 to S106. While the steps S104 to S106 are executed, for example, polling or the like between the portable information terminal 100 and the AED 1 is not executed but the portable information terminal 100 side only detects the wireless signal unilaterally.
The management computer 200 receives the notification information transmitted in the step S106 (step S107). Next, the management computer 200 transmits the information for notification about the activation of the AED 1 or the position information of the portable information terminal 100 to the computer apparatus 300 (step S108). Then, the management computer 200 ends the process. The step S108 may be executed based on an operation input of the user of the management computer 200, for example, only when the user judges that the step S108 is necessary.
Next, the flowchart of
The portable information terminal 100 establishes communication connection with the AED 1 (step S111). In the step S111, for example, authentication based on polling etc. is executed so that transmission/reception of data between the AED 1 and the portable information terminal 100 can be made.
Next, the portable information terminal 100 receives rescue data that the AED 1 has acquired by the life rescue actions from the AED 1 (step S112). The rescue data received in the step S112 are, for example, physiological information such as electrocardiogram data of a person in need for rescue. In addition, after the AED 1 has completed the self-test, the portable information terminal 100 receives a result of the self-test in the step S112.
Next, the portable information terminal 100 transmits the rescue data or the result of the self-test acquired in the step S112 to the management computer 200 (step S113). Next, the management computer 200 receives the information transmitted in the step S113 (step S114).
Next, the management computer 200 transmits the information acquired in the step S114 to the computer apparatus 300 (step S115). Incidentally, when the information acquired in the step S114 is the result of the self-test, the step S115 does not have to be executed. In addition, the step S115 may be executed based on an operation input of the user, for example, only when the user of the management computer 200 judges that the step 115 is necessary.
Successively, effects obtained by the system 400 according to the present embodiment or by the respective constituents included in the system 400 will be described.
The portable information terminal 100 detects the wireless signal from the AED 1. Upon the detection, the portable information terminal 100 notifies the management computer 200 of the activation of the AED 1 without establishing communication connection with the activated AED 1. That is, the portable information terminal 100 can more surely contact the manager or the like about the fact that the AED 1 has been activated while reducing a load on the AED 1 due to avoidance of the communication connection between the activated AED 1 and the portable information terminal 100.
In addition, an approximate position at which the AED 1 is activated can be confirmed based on the position information of the portable information terminal 100. Accordingly, life rescue activity can be supported easily on the side of the user of the management computer 200 or the user of the computer apparatus 300.
In addition, the configuration is made not to acquire the position information of the AEDs 1 but to acquire the position information of the portable information terminal 100. Accordingly, it is not necessary to mount the GPS sensor on each of the AEDs 1 so that battery consumption or manufacturing cost of the AED 1 side can be suppressed. In addition, when the portable information terminal 100 supports acquisition of the position information corresponding to its usage area, nothing is required to be additionally mounted on the AED 1 side about the position information. That is, even if the AEDs 1 are of a single model type, the position information corresponding to various areas can be acquired.
In addition, the portable information terminal 100 transmits the individual information to the management computer 200. Accordingly, the individual information about the AED 1, the portable information terminal 100 or the user of the portable information terminal 100 can be known on the user side of the management computer 200. As a result, the user of the management computer 200 can easily support the life rescue activity. For example, when a contact address such as a telephone number of the portable information terminal 100 is included in the individual information, the user of the management computer 200 can also contact the user of the portable information terminal 100 to give a proper instruction thereto.
In addition, at the predetermined timing, such as after the series of life rescue actions has been terminated, the AED 1 transmits, to the portable information terminal, the physiological information such as the electrocardiogram data of the person in need for rescue and the portable information terminal 100 transmits the physiological information received from the AED 1 to the management computer 200. As a result, it is possible to determine whether a further emergency measure on the person in need for rescue is required or not so that the user side of the management computer 200 can easily support the rescue activity. In addition, the user of the management computer 200 can transmit the physiological information to the computer apparatus 300 installed in the hospital or the like as occasion demands. Accordingly, a suitable and rapid measure can be easily made in the hospital or the like.
In addition, the portable information terminal 100 can set only a specific AED 1 as the detection target. Accordingly, it is possible to prevent such a situation that the user of the management computer 200 is confused because the user side is also notified of activation from any other AED 1 not managed by the user. In addition, the detection target is set suitably. Thus, when the user or the like of the management computer 200 organizes emergency staffs to build a rescue system, the rescue system can be built easily and suitably.
In addition, the time interval at which the AED 1 is detected can be set by the user side of the portable information terminal 100. Thus, for example, it is possible to select the detection interval suitably in accordance with the scale of the rescue system, the role of the user, a remaining level of the battery of the portable information terminal 100, etc.
In addition, when the wireless communicator 90 of the AED 1 is compatible with the wireless LAN standard or the Bluetooth standard, a beacon conforming to these standards is sent as the wireless signal. Accordingly, the AED 1 is easily detected. In addition, when the wireless communicator 90 is compatible with the wireless LAN standard, the AED 1 can be detected within a comparatively wide range of a circle with a radius of about 100 m from the portable information terminal 100. On the other hand, when the wireless communicator 90 is compatible with the Bluetooth standard, a circle with a radius of about 10 m from the portable information terminal 100 is within the detection range. Accordingly, a difference between the position of the AED 1 and the position indicated by the position information of the portable information terminal 100 is reduced so that the position where the AED 1 is activated can be known more accurately.
The aforementioned embodiment is merely exemplar in order to make the presently disclosed subject matter easy to understand. The configuration according to the aforementioned embodiment can be changed/improved properly without departing from the gist of the presently disclosed subject matter. The present application is based on Japanese Patent Application No. 2020-098726 filed on Jun. 5, 2020, the entire contents of which are hereby incorporated by reference.
