<Embodiment 1>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a medical system 1 according to the present embodiment. The medical system 1 includes a medical device 10 (first medical device) and a medical device 20 (second medical device). In FIG. 1, the internal configurations of the medical device 10 and the medical device 20 are simplified (the detailed configuration will be described later with reference to FIG. 2 and the like). In FIG. 1, two medical devices (10, 20) are assumed to be present. However, the present invention is not necessarily limited to this, and the medical system 1 may be composed of three or more medical devices.

  The medical device 10 and the medical device 20 mutually transmit and receive data by wireless communication. That is, the device (opposite medical device) to be connected to the medical device 10 is the medical device 20. The medical device 10 includes a communication unit 110 that performs wireless communication as illustrated, and the medical device 20 includes a communication unit 210 that performs wireless communication as illustrated.

  A use use case example of the medical device 10 and the medical device 20 will be briefly described. The medical device 10 and the medical device 20 transmit / receive data to / from each other at a disaster site or the like. For example, it is assumed that the medical device 10 is a medical telemeter and the medical device 20 is a defibrillator. A lifesaving person or the like uses a medical telemeter (medical device 10) to measure each biological parameter (arterial oxygen saturation, pulse, respiration, etc.) of the patient. Assume that the defibrillator (medical device 20) arrives thereafter. In this case, the defibrillator (medical device 20) performs treatment after taking in each biological parameter of the patient measured by the medical telemeter (medical device 10).

  The medical device 10 and the medical device 20 are arbitrary medical devices such as a bedside monitor, a Holter electrocardiograph, a BIS monitor, a CO2 monitor, and an AED (Automated External Defibrillator) as long as they have a wireless communication function. Also good.

  Next, a detailed configuration of the medical device 10 will be described with reference to FIG. The medical device 10 includes a communication unit 110, a biological signal input unit 120, a control unit 130, a storage unit 140, an operation unit 150, and a notification unit 160.

  The communication unit 110 performs wireless communication with the medical device 20 that is the opposite medical device (medical device to be connected) of the medical device 10. The communication unit 110 establishes a wireless connection with the medical device 20 and transmits and receives data. Various realization methods can be considered for connection with the medical device 20 by the communication unit 110. For example, the communication unit 110 may establish a connection with the medical device 20 by implementing an arbitrary short-range wireless standard or an infrared communication function. Each function of the communication unit 110 is realized by executing a program stored in the storage unit 140 and executing various circuits. The communication unit 110 may be realized as a small device (so-called dongle) that can be attached to and detached from the medical device 10.

The wireless connection status by the communication unit 110 is, for example, “not connected”, “connecting process in progress (authentication or connection establishment process in progress)”, “connecting”, “connecting (data transmission / reception)”, “connection error "," Connection completed ".

  The biological signal input unit 120 is electrically connected to a biological sensor such as an electrode attached to the patient's living body, and acquires the patient's biological signal. The biological signal input unit 120 supplies the acquired biological signal of the patient to the control unit 130.

  The storage unit 140 is a storage device that stores various data. The various types of data include data such as measured values and waveforms of each biological parameter calculated based on a patient's biological signal, a program used for controlling the medical device 10, and the like. The storage unit 140 may be a memory or a hard disk, or may be a USB (Universal Serial Bus) memory configured to be detachable from the medical device 10. The storage unit 140 is a concept including a temporary storage device (for example, a cache memory) used by the CPU. The control unit 130 appropriately reads / writes data from / to the storage unit 140.

  The operation unit 150 is an input interface that receives input from a user (doctor, firefighter, etc.). For example, the operation unit 150 is a button, a knob, a trim knob, or the like provided on the housing of the medical device 10. The operation unit 150 notifies the control unit 130 of input from the user (such as pressing a button).

  The notification unit 160 performs at least one of light emission notification, auditory notification, and vibration notification (tactile notification) to the user in accordance with control from the control unit 130. The notification unit 160 includes a display unit 161, a vibration notification unit 162, a light emission notification unit 163, and an auditory notification unit 164.

  The display unit 161 is a display device such as an LCD (Liquid Crystal Display) or a CRT (Cathode Ray Tube) provided on the housing of the medical device 10. The display unit 161 displays, for example, various biological parameter measurement values (respiration rate, etc.), biological waveforms, and the like.

  The vibration notification unit 162 vibrates the housing of the medical device 10 under the control of the control unit 130. The vibration notification unit 162 includes, for example, a vibration motor including a weight, a circuit that controls the vibration motor, and the like.

  The light emission notification unit 163 emits light under the control of the control unit 130. The light emission notification unit 163 includes, for example, an indicator lamp provided on the housing of the medical device 10, a circuit that controls the indicator lamp, and the like. It is desirable that the indicator lamp constituting the light emission notification unit 163 is configured to emit light in a plurality of colors so that the wireless communication state of the communication unit 110 can be clearly notified. Alternatively, it is desirable to provide a plurality of indicator lamps for each color.

  The hearing notification unit 164 outputs an electronic sound, a message sound, and the like. The hearing notification unit 164 includes a speaker, a control circuit for the speaker, and the like. The auditory informing unit 164 notifies the wireless communication state of the communication unit 110 by sound in addition to the alarm sound when each biological parameter is abnormal.

  The vibration notification unit 162, the light emission notification unit 163, and the auditory notification unit 164 notify the wireless communication state of the communication unit 110 under the control of the control unit 130. The notification control of the wireless communication state will be described later with reference to FIG. 3 and FIG.

  Note that the operation unit 150 and the display unit 161 may be integrated (preferably a touch panel). In addition, the notification unit 160 does not necessarily have the configuration including all the processing units (161 to 164) described above, and at least one of the vibration notification unit 162, the light emission notification unit 163, and the auditory notification unit 164 is mounted. Any configuration may be used.

  The control unit 130 controls the medical device 10 and reads various programs from the storage unit 140 and executes them. The function of the control unit 130 is realized by a CPU (Central Processing Unit) provided in the medical device 10 executing a program and its peripheral circuits performing processing.

  An example of control by the control unit 130 will be described below. The control unit 130 performs control such as measurement start and measurement end of each biological parameter in accordance with an input from the operation unit 150. In addition, the control unit 130 performs various signal processing on the biological signal supplied from the biological signal input unit 120 to thereby obtain measurement values and waveforms of each biological parameter (pulse rate, respiratory rate, SpO2, blood pressure, etc.). calculate. The control unit 130 stores the calculated measurement value and waveform in the storage unit 140 and displays them on the display unit 161.

  In addition, the control unit 130 performs notification control of the wireless communication state of the communication unit 110. Specifically, the control unit 130 monitors the operation of the communication unit 110, and the wireless connection state of the communication unit 110 (“connection processing in progress”, “connecting”, “connecting (data transmission / reception)”), “connection error” "," End of connection ", etc.) are detected. The control unit 130 performs at least one of vibration notification (notification by the vibration notification unit 162), light emission notification (notification by the light emission notification unit 163), and auditory notification (notification by the auditory notification unit 164) according to the detected wireless connection state. Do. An example of the notification pattern is shown in FIG.

  FIG. 3A shows an example of a notification pattern when the wireless communication state is notified by light emission of the light emission notification unit 163. When the communication unit 110 is performing the connection process (in the state before the connection is established), the control unit 130 controls the light emission notification unit 163 to blink the green indicator lamp. Similarly, when the communication unit 110 is connected, the control unit 130 controls the light emission notification unit 163 to turn on the green indicator lamp. When the communication unit 110 performs data transmission / reception, the control unit 130 controls the light emission notification unit 163 to turn on the green and blue indicator lamps. When the communication unit 110 has caused a connection error, the control unit 130 controls the light emission notification unit 163 to turn on the red indicator lamp. When the communication unit 110 ends the connection with the opposing device (medical device 20), the control unit 130 controls the light emission notification unit 163 to turn off all indicator lamps.

  Note that the light emission notification unit 163 may increase the light emission amount compared to the normal state when the wireless communication state is abnormal (for example, when a connection error occurs or when the connection process takes a certain time or more). In an abnormal state, the amount of light emission increases, so that the user can more easily recognize the wireless communication state. Since the user can immediately recognize the error, the connection setting or the like can be quickly changed.

  Note that the light emission notification unit 163 may emit light only when the wireless communication state is abnormal (for example, when a connection error occurs or when the connection process takes a certain time or longer).

  In the example of FIG. 3A, the light emission notification unit 163 emits light of a plurality of colors, but it is of course possible to notify the wireless communication state by controlling the light emission timing of the single color indicator lamp. .

  FIG. 3B shows an example of a notification pattern when the hearing notification unit 164 notifies the wireless communication state. When the communication unit 110 is performing the connection process (in a state before the connection is established), the control unit 130 controls the hearing notification unit 164 to output a “beep beep” sound. Similarly, when the communication unit 110 is connected, the control unit 130 controls the hearing notification unit 164 to output a “ping-pong” sound. When the communication unit 110 performs data transmission / reception, the control unit 130 controls the auditory notification unit 164 to output a “beep” sound. When the communication unit 110 has caused a connection error, the control unit 130 controls the auditory notification unit 164 to output a “boo boo” sound. When the communication unit 110 ends the connection with the opposing device (medical device 20), the control unit 130 controls the auditory notification unit 164 to stop all sound output.

  Note that the hearing notification unit 164 may increase the output volume as compared with the normal state when the wireless communication state is abnormal (for example, when a connection error occurs or when the connection process takes a certain time or more). In the case of an abnormal state, the output volume is increased, so that the user can more easily recognize the wireless communication state. Since the user can immediately recognize the error, the connection setting or the like can be quickly changed.

  Note that the audio notification unit 164 may output sound only when the wireless communication state is abnormal (for example, when a connection error occurs or when the connection process takes a certain time or longer).

  In addition, although not shown, it is also possible to notify the wireless communication state by changing the vibration pattern of the vibration notification unit 162.

  It is also possible to change the notification method according to the type of wireless communication state. For example, if the wireless communication status is abnormal (for example, if a connection error occurs or if the connection process takes more than a certain time), a sound notification is given, and if it is normal, a light emission notification is given. Also good.

  It is also possible to notify the wireless communication state by combining light emission notification, vibration notification, and pronunciation notification. For example, the control unit 130 notifies each state using the light emission notification unit 163. Here, when a connection error occurs, the control unit 130 performs notification (auditory notification) by the auditory notification unit 164 in addition to notification by the light emission notification unit 163 (light emission notification). As a specific example, when a connection error occurs, the control unit 130 may perform control to turn on the red indicator lamp and output an error sound.

  In addition, the user may perform a setting operation from the operation unit 150 to set a method for notifying the wireless communication state. For example, the user presses a button while referring to the setting screen displayed on the display unit 161 to perform notification by any method (light emission notification, vibration notification, and pronunciation notification by any method). Notification may be set.

  With reference to the flowchart of FIG. 4, the notification control of the wireless communication state by the medical device 10 will be described again. The communication unit 110 starts a wireless connection with the medical device 20 that is the opposite device. The control unit 130 monitors the operation of the communication unit 110, and the wireless connection state of the communication unit 110 (“connection processing in progress”, “connected”, “connected (data transmission / reception)”, “connection error”, “ The connection end "and the like are monitored, and the start of the connection process is detected (S11: Yes). The control unit 130 continues monitoring until the connection process is started (S11: No).

  When the connection process is started (S11: Yes), the control unit 130 notifies the wireless communication state via the notification unit 160 (at least one of light emission notification, vibration notification, and auditory notification) (S12). The control unit 130 continues to monitor the operation of the communication unit 110 and monitors whether there is a change in the wireless connection state of the communication unit 110 (S13).

  When the connection state changes (S13: connection state change), the control unit 130 performs notification control according to a predetermined notification pattern (for example, FIG. 3A or FIG. 3B) (S14). For example, the control unit 130 changes the notification sound and the light emission pattern by the notification unit 160 (S14).

  In addition, when the communication unit 110 ends the connection with the medical device 20 (S13: connection end), the control unit 130 ends the connection according to a predetermined notification pattern (for example, FIG. 3A or FIG. 3B). (S15), and it is monitored again whether connection start processing occurs (S11).

  The above is the configuration and operation of the medical device 10. Next, the configuration of the medical device 20 will be described with reference to FIG. The medical device 20 includes a communication unit 210, a biological signal input unit 220, a control unit 230, a storage unit 240, an operation unit 250, and a notification unit 260. The notification unit 260 includes a display unit 261, a vibration notification unit 262, a light emission notification unit 263, and an auditory notification unit 264. The configuration of the medical device 20 is basically the same as the configuration of the medical device 10 shown in FIG. A processing unit having the same processing unit name as that of the medical device 10 basically performs the same operation as in FIG.

  Note that the medical device 10 and the medical device 20 have processing units (not shown) depending on applications and functions. For example, when the medical device 10 is a medical telemeter capable of noninvasive blood pressure measurement, the medical device 10 includes a pump for controlling the cuff pressure in addition to the configuration of FIG. Similarly, when the medical device 20 is a defibrillator, the medical device 20 includes a processing unit for amplifying an electrocardiogram signal and a high-voltage capacitor in addition to the configuration of FIG.

  Similarly to the medical device 10, the medical device 20 notifies the wireless communication state of the communication unit 210 by at least one method of light emission notification, vibration notification, and auditory notification. Here, when performing auditory notification (sound output), only one of the medical device 10 and the medical device 20 may output sound. For example, the medical device 20 notifies the wireless communication state of the communication unit 210 by light emission. The medical device 10 notifies the wireless communication state of the communication unit 110 by emitting light and outputting sound. Thereby, the trouble (noisiness) by mixing the output sound from the medical device 10 and the output sound from the medical device 20 can be reduced, and the possibility of causing confusion can be avoided.

  Then, the effect of the medical system 1 concerning this Embodiment is demonstrated. As described above, the medical device 10 detects a wireless communication state, and notifies the detected wireless communication state by at least one method of light emission notification, vibration notification, and auditory notification. That is, the medical device 10 notifies the wireless communication state by a method other than displaying on the display. Thereby, the user can easily recognize the wireless communication state between the medical devices.

  The medical device 10 switches the notification method according to the type of the wireless communication state of the communication unit 110. For example, when the wireless communication state is an error, the light emission notification and the auditory notification are performed at the same time, and when it is not an error, only the light emission notification is performed. As a result, the user can more accurately recognize the problematic state.

<Embodiment 2>
The medical device 10 according to the second embodiment is characterized in that the size of the notification sound and the light emission amount are changed according to the surrounding volume and light amount. The difference between the medical device 10 according to the present embodiment and the first embodiment will be described below. In the following drawings, processing units having the same names and symbols as those of the first embodiment are assumed to have the same processing and configuration as those of the first embodiment unless otherwise specified (the same applies to the third embodiment). Is).

  The overall configuration of the medical system 1 is the same as that in FIG. 1, but of course there may be three or more medical devices. FIG. 6 is a block diagram illustrating a configuration of the medical device 10 according to the present embodiment. The medical device 10 according to the present embodiment includes an optical sensor 170 and a sound sensor 180 in addition to the configuration of the first embodiment (FIG. 2).

  The optical sensor 170 is a sensor that measures the brightness (illuminance) around the medical device 10. The optical sensor 170 includes a light receiving element as in a general illuminance sensor, and may detect brightness (illuminance) by converting light incident on the light receiving element into an electric current. The optical sensor 170 notifies the control unit 130 of information on the detected peripheral brightness (illuminance).

  The sound sensor 180 is a sensor that measures the volume of sound around the medical device 10. The sound sensor 180 may include, for example, a general microphone element and detect the volume of ambient sounds. The sound sensor 180 notifies the controller 130 of information on the detected surrounding volume.

  The control unit 130 controls the notification light emission amount in the wireless communication state according to the surrounding brightness (illuminance) detected by the optical sensor 170. For example, when the surrounding brightness (illuminance) is a certain value or more (that is, when it is bright), the control unit 130 increases the light emission amount of the light emission notification unit 163. On the other hand, when the surrounding brightness (illuminance) is less than a certain value (that is, when it is dark), the control unit 130 decreases the light emission amount of the light emission notification unit 163.

  This makes it possible to easily recognize the wireless communication state even when the surroundings are bright. Further, since the amount of light emission when the periphery is dark is suppressed, the user does not feel dazzling.

  Further, the control unit 130 controls the notification volume of the wireless communication state according to the volume of the surrounding sound detected by the sound sensor 180. For example, when the surrounding sound volume is equal to or higher than a certain value (that is, when the sound volume is noisy or noisy), the control unit 130 increases the output sound volume of the audio notification unit 164. On the other hand, for example, when the surrounding sound volume is less than a certain value (that is, when the sound volume is quiet), the control unit 130 decreases the output sound volume of the audio notification unit 164.

  Thereby, even when the surrounding volume is high (when it is noisy or lively), the user can appropriately grasp the wireless communication state. Further, even when the surrounding volume is low (when quiet), the user does not feel bothered by the notification sound of the wireless communication state.

  Of course, only one of the optical sensor 170 and the sound sensor 180 may be built in. For example, when the wireless communication state is notified only by the light emitted from the indicator lamp, only the optical sensor 170 needs to be incorporated. Similarly, when the wireless communication state is notified only by the output sound, only the sound sensor 180 needs to be incorporated.

<Embodiment 3>
The medical device 10 according to the third embodiment is characterized in that the auditory notification in the wireless communication state is suppressed when the patient's biological abnormality is detected. The difference between the medical device 10 according to the present embodiment and the first embodiment will be described below.

  The configuration of the medical system 1 in the present embodiment is the same as the configuration of FIG. 1, and the configurations of the medical device 10 and the medical device 20 are the same as those of FIGS.

  The control unit 130 according to the present embodiment detects a patient's biological abnormality based on the biological signal acquired by the biological signal input unit 120. For example, the control unit 130 calculates a measurement value or waveform of each biological parameter (respiration waveform, respiratory rate, arterial oxygen saturation, pulse rate, electrocardiogram, etc.) based on the biological signal. Then, the control unit 130 determines whether each calculated biological parameter is in a normal range, a normal waveform, or the like. The determination process may be substantially the same as the determination process of a vital alarm or a technical alarm performed in a general biological information monitor or a defibrillator. That is, the biological abnormality is a concept including an abnormality relating to a technical alarm in addition to an abnormality relating to a vital alarm.

  When the control unit 130 detects a biological abnormality by the above-described determination (for example, when a situation corresponding to a vital alarm or a technical alarm is detected), the control unit 130 suppresses the auditory notification by the auditory notification unit 164 in the wireless communication state and performs other notifications. Control is performed to perform the method (vibration notification, light emission notification). That is, the notification unit 160 notifies the wireless communication state by vibration or light emission when a biological abnormality occurs.

  The process flow of the medical device 10 according to the present embodiment will be described again with reference to FIG. The control unit 130 calculates the measurement value and waveform of each biological parameter based on the biological signal, and determines whether each measurement value and waveform is abnormal (that is, whether a biological abnormality has occurred) (S21). . When a biological abnormality has occurred (S21: Yes), the control unit 130 is set to suppress notification of the wireless communication state from the auditory notification unit 164 and perform notification (vibration notification, light emission notification) by other methods. (S22). In addition, the control unit 130 outputs an alarm sound that informs of a biological abnormality via the auditory notification unit 164 (S22). Subsequent processing (processing after S11) is the same as FIG.

  On the other hand, when the biological abnormality does not occur (S21: No), the control unit 130 does not change the notification method. Subsequent processing (processing after S11) is the same as FIG.

  Then, the effect of the medical system 1 concerning this Embodiment is demonstrated. The medical device 10 according to the present embodiment suppresses notification of the wireless communication state by sound when a biological abnormality occurs. As a result, the alarm sound regarded as more important is surely heard by the user. In addition, since the wireless communication state is notified by vibration or light emission, various states surrounding the patient can be reliably grasped.

<Embodiment 4>
The medical system 1 according to the present embodiment is characterized by performing notification using a notification pattern corresponding to the medical device 10 and the medical device 20. Hereinafter, the difference of the configuration of the medical system 1 according to the present embodiment from the above-described embodiment will be described.

  The configuration of the medical system 1 according to the present embodiment is substantially the same as that shown in FIG. 1, but it is assumed that a plurality of medical devices are often used in a narrow space. FIG. 8 is a conceptual diagram showing a configuration of the medical system 1 according to the present embodiment. As shown in the figure, there are a plurality of medical devices (10-1, 10-2, 20-1, 20-2). The medical devices 10-1 and 10-2 correspond to the medical device 10 in FIG. 2, and the medical devices 20-1 and 20-2 correspond to the medical device 20 in FIG.

Here, medical devices that are paired in connection use the same notification pattern. For example, it is assumed that the medical device 10-1 and the medical device 20-1 are trying to connect as shown in FIG. The communication unit 110 in the medical device 10-1 transmits to the medical device 20-1 which notification pattern is used when starting the connection process (for example, when transmitting an authentication code to the medical device 20-1). Here, the notification pattern defines how light emission, vibration, and pronunciation are performed. For example, when notifying the wireless communication state, it is assumed that the following notification patterns are determined in advance.
Notification pattern 1 = Notification using a blue lamp Notification pattern 2 = Notification using a green lamp Notification pattern 3 = Notification using a blue lamp, a green lamp, and a red lamp Notification pattern 4 = Blue lamp and sound Notification / notification pattern 5 used = Notification using sound (notification based on the sound of “beep”)
-Notification pattern 6 = Notification using sound (notification based on the sound of "buzz")

  That is, the communication unit 110 in the medical device 10-1 selects one of the above six notification patterns and transmits it to the medical device 20-1. The medical device 10-1 and the medical device 20-1 notify the wireless communication state according to the selected notification pattern. In the example of FIG. 8, the medical device 10-1 and the medical device 20-1 notify the wireless communication state using the notification pattern 1.

  Similarly, the communication unit 110 in the medical device 10-2 selects one of the above six notification patterns and transmits it to the medical device 20-2. The medical device 10-2 and the medical device 20-2 notify the wireless communication state according to the selected notification pattern. In the example of FIG. 8, the medical device 10-2 and the medical device 20-2 notify the wireless communication state using the notification pattern 2.

  In this way, each pair of medical devices performs notification using the same notification pattern, and in principle, when the pairs are different, different notifications are performed. For example, even when two pairs are transmitting and receiving data, the two medical devices constituting each pair notify the wireless communication state with the same notification pattern. Thereby, the user can easily understand the mutual connection relationship of a plurality of medical devices. Since the connection relationship between medical devices (pairing relationship) can be easily recognized without checking the screen, it is possible to quickly transfer data and use medical devices even during terrorism and large-scale disasters. .

  Note that the above-described notification pattern may be selected according to, for example, a user input instruction, or may be selected at random after defining many notification patterns. The above description is an example of using the same notification pattern for each pair of medical devices. If the same notification pattern can be used for each pair of medical devices, other implementations may be used. You can go.

  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.
