Each embodiment of the present invention will be described below with reference to the drawings.
In the specification and the drawings of the application, components similar to those described in regard to a drawing thereinabove are marked with like reference numerals, and a detailed description is omitted as appropriate.

(First embodiment)
FIG. 1A and FIG. 1B are schematic views illustrating the care/medical communication device and the care/medical communication system according to the first embodiment.
As shown in these drawings, the care/medical communication system 310 includes, for example, a care/medical communication device 110 and a receiving device 210.

The care/medical communication device 110 according to the present embodiment includes an input unit 10, a wireless module 20, and a switching unit 30. As described below, the wireless module 20 implements at least two modes of operation. FIG. 1A shows an example of the first mode operation in the wireless module 20. FIG. 1B shows an example of the second mode operation in the wireless module 20.

As shown in FIG. 1A, the input unit 10 receives a data signal DS relating to the state of the subject. The target person is a person who receives nursing care and medical care. The input unit 10 may include, for example, the first input terminal 10a and the second input terminal 10b. The first signal Sig1 is input to the first input terminal 10a. The second signal Sig2 is input to the second input terminal 10b. These signals are included in the data signal DS.

The first signal Sig1 is, for example, a detection signal detected by a load detection unit described later. The load detection unit is installed in, for example, a bed used by the subject. For example, when the subject shifts from a state of sleeping on the bed to a state of leaving the bed, the load detected by the load detection unit becomes small. At this time, the detection signal (first signal Sig1) is transmitted from the load detector to the first input terminal 10a. The state of getting out of bed of the subject is detected by such a detection signal. For example, when the target person shows a wandering behavior, such a detection signal allows the wandering behavior to be detected and appropriate measures to be taken. An example of the load detector will be described later.

The second signal Sig2 is, for example, a bed information signal regarding the state of the bed used by the subject. The bed state signal (second signal Sig2) includes, for example, information about the angle of the bed, the height from the floor, and the like. The bed state signal may include, for example, information from a bed peripheral device provided associated with the bed.

The detection signal (first signal Sig1) is, for example, a signal corresponding to two states of ON/OFF. On the other hand, the bed state signal (second signal Sig2) includes a lot of information. By making it possible to transmit not only the detection signal but also the bed signal, more advanced care and medical care will be possible. Examples of the detection signal and the bed state signal will be described later.

The wireless module 20 transmits a wireless signal based on such a data signal DS in one mode of operation. The transmitted wireless signal is received by the receiving device 210. The receiving device 210 includes, for example, an antenna 213, a wireless circuit unit 220, a notification unit 211, a control unit 218, and the like. The transmitted wireless signal is received by the antenna 213 and the wireless circuit unit 220. The notification unit 211 performs, for example, at least one of display, light emission, sound, and vibration. These are done by the received signal. For example, when the target person leaves the bed, the user is informed of the fact by display, light emission, sound or vibration.

The user is, for example, a person who performs care (a caregiver) and a medical worker (a nurse or a doctor). In this way, the content received by the receiving device 210 can be grasped by the user. As a result, the user recognizes the information included in the data signal DS and takes appropriate action. Such an operation corresponds to, for example, the detection/transmission mode.

In addition to this, the wireless module 20 can implement another mode of operation. In this other mode, the operation of the wireless relay device is performed. This operation corresponds to the relay mode.

Such at least two operations are switched by the switching unit 30.

That is, as shown in FIG. 1A, when the switching unit 30 is in the first state S1, the wireless module 20 performs the first mode operation MO1 of transmitting the first wireless signal W1 based on the data signal DS. ..

On the other hand, in FIG. 1B, one care/medical communication device 110 and another care/medical communication device 110a are illustrated. In another care/medical communication device 110a, the wireless module 20 performs the first mode operation MO1. In the care/medical communication device 110, the wireless module 20 implements the second mode operation MO2. A first radio signal W1 based on the data signal DS is transmitted from the nursing/medical communication device 110a in the first mode operation MO1. The first wireless signal W1 is received by the care/medical communication device 110 as the second wireless signal W2, and the relay signal W3 is transmitted from the care/medical communication device 110. That is, the nursing/medical communication device 110 relays the first wireless signal W1 (second wireless signal W2) and transmits the relay signal W3.

As will be described later, in the second mode operation MO2 (relay mode), for example, wireless signals from the plurality of nursing/medical communication devices 110a in the first mode operation MO1 may be relayed.

Thus, as shown in FIG. 1B, in the care/medical communication device 110, when the switching unit 30 is in the second state S2, the wireless module 20 responds to the received second wireless signal W2. The second mode operation MO2 of transmitting the relay signal W3 is performed.

In this way, the two modes are switched by the switching unit 30. As a result, it is possible to provide a care/medical communication device and a care/medical communication system capable of stable communication.

If the amount of data contained in the data signal DS is small, it is possible to transmit by a radio signal having a relatively low frequency. The distance over which this wireless signal reaches is relatively long. For example, when only a simple signal such as a detection signal detected by the load detection unit is targeted, it is considered that long-distance wireless communication can be performed by a wireless signal having a relatively low frequency. For example, in such a case, a frequency of 400 MHz band is used.

On the other hand, when the amount of data included in the data signal DS is large, a radio signal having a relatively high frequency is used. In such a case, a frequency of 920 MHz band is used, for example. However, the distance over which the high frequency radio signal reaches is relatively short. Therefore, when the distance between the wireless transmission device and the reception device 210 becomes a certain distance or more, stable communication becomes difficult. Or communication is not possible. In such a case, it may be possible to provide a relay device. The relay device relays the wireless signal transmitted from the transmitting device, and the relayed wireless signal is received by the receiver. This enables long-distance communication even with a large amount of data.

When a high frequency (for example, 920 MHz band) frequency that can support communication of such a large amount of data is used, generally, the transmission device and the relay device are manufactured as separate devices. For example, the transmission device does not operate as a relay device. On the other hand, for example, the relay device only acquires the radio signal and relays it, and does not acquire the data signal DS. Therefore, the relay device does not perform the operation of transmitting the radio signal based on the data signal DS.

However, when the transmission device and the relay device are manufactured as separate devices in this way, it may be practically inconvenient. First, when the transmitter and the relay device are purchased as separate devices, the price is high. On the other hand, it is increasing that these devices are rented and used. For example, when caring for an elderly person, such a device is often borrowed from a dealer who handles care and medical supplies. In this case, in the dealer, it is necessary to separately prepare the transmission device and the relay device in order to meet the request of the user. Inventories increase, handling becomes complicated, and as a result, rental fees rise. These factors cause a slowdown in the spread of nursing care/medical communication devices and their systems.

Furthermore, even in a nursing/medical facility that accommodates a large number of target persons, if the transmitting device and the relay device are different, it is necessary to separately prepare spares for these devices. When it is desired to change the position of the bed or the area where the target person is active in the facility, it is necessary to prepare many transmitting devices and many relay devices in advance so as to be able to cope with the situation immediately. Furthermore, for example, when one of the transmitting devices fails, even if there is a relay device, the transmission cannot be performed. Therefore, it is necessary to prepare many transmission devices and many relay devices in advance.

In the embodiment, the care/medical communication device 110 is switched between the detection/transmission mode and the relay mode by switching the switching unit 30. As a result, when rented, the stock at the dealer can be reduced. As a result, the management cost of the dealer and the rental fee are reduced. Even in a nursing care/medical facility, it is not necessary to prepare many transmitting devices and many relay devices in advance. As a result, when it is desired to change the position of the bed or the area in which the subject is active, it is possible to immediately respond.

In this way, by switching the switching unit 30, the detection/transmission mode and the relay mode are switched, so that stable communication becomes possible. As a result, more advanced nursing and medical services can be provided. For example, long-distance stable communication is possible even with a large amount of data.

On the other hand, a reference example in which a wireless module in the detection/transmission mode and a wireless module in the relay mode are separately provided in one device can be considered. In this case, the two wireless modules increase the size of the device and increase the cost.

On the other hand, in the embodiment, one wireless module is used and the operation mode is switched by the switching unit 30. As a result, the size of the device is small and the cost can be suppressed.

Hereinafter, an example of the care/medical communication device 110 will be further described with reference to FIG.

The care/medical communication device 110 may further include an antenna 60, a storage unit 50, and a battery 40 in addition to the input unit 10, the wireless module 20, and the switching unit 30.

The antenna 60 emits the signal output from the wireless module 20 as the first wireless signal W1.

The storage unit 50 stores, for example, a program (for example, firmware) related to the wireless module 20. The storage unit 50 stores at least two programs (a first program, a second program, etc.). For example, the first mode operation MO1 is performed when the wireless module 20 operates based on the first program (see FIG. 1A). For example, when the wireless module 20 operates based on the second program, the second mode operation MO2 is performed (see FIG. 1B). Thus, for example, when the switching unit 30 is in the first state S1, the wireless module 20 implements the first mode operation MO1 based on the first program stored in the storage unit 50. For example, when the switching unit 30 is in the second state S2, the wireless module 20 implements the second mode operation MO2 based on the second program stored in the storage unit 50.

In this way, two modes are switched by selecting a plurality of firmware stored in the storage unit 50. For the storage unit 50, for example, a ROM or the like is used.

The battery 40 supplies power to, for example, the wireless module 20 and the storage unit 50. The battery 40 may be, for example, a rechargeable battery or a non-rechargeable battery (such as a dry battery). For example, the care/medical communication device 110 may be provided with the power input terminal 45. A power line 45L can be connected to the power input terminal 45. For example, when the battery 40 is rechargeable, the battery 40 may be charged by the electric power obtained from the power input terminal 45. When power is supplied to the power supply input terminal 45 from the power supply line 45L, the operation in the nursing/medical communication device 110 may be performed based on the power supplied from the power supply line 45L.

For example, when the care/medical communication device 110 is used in the first mode operation MO1 (detection/transmission mode), the care/medical communication device 110 is provided near the bed. In such a case, if the power supply line 45L is connected to the power supply input terminal 45, the subject or the user can easily contact the power supply line 45L or the like. It may also cause an accident. Therefore, in the first mode operation MO1, it is preferable that the power supply line 45L is not connected to the power supply input terminal 45. The first mode operation MO1 is preferably performed by the electric power supplied from the battery 40.

On the other hand, in the second mode operation MO2 (relay mode), for example, the wireless signals of the care/medical communication device 110a in the plurality of first mode operations MO1 are relayed. Therefore, there is a strong need for the second mode operation MO2 (relay mode) to be always performed without depending on the battery 40. Therefore, in the second mode operation MO2, it is preferable that power is supplied to the power input terminal 45 from the power line 45L. The second mode operation MO2 is preferably performed by the electric power input from the power supply line 45L.

On the other hand, it is preferable that the care/medical communication devices 110 and 110a continue to operate even when there is a power failure or the like. Therefore, the second mode operation MO2 may be implemented by the electric power supplied from the battery 40.

For example, when power is supplied to the power input terminal 45 from the power line 45L, the first mode operation MO1 and the second mode operation MO2 are performed by this power. When power is not supplied from the power line 45L to the power input terminal 45, the first mode operation MO1 and the second mode operation MO2 are performed by the power from the battery 40. For example, an operation in which power from the power line 45L is prioritized is performed.

Hereinafter, an example of use of the care/medical communication device 110 will be described.
FIG. 2 is a schematic view illustrating a usage state of the nursing/medical communication device according to the first embodiment.
In the example shown in FIG. 2, in the care/medical communication device 110, the first mode operation MO1 (detection/transmission mode) is performed. As shown in FIG. 2, a mattress 86a (for example, a futon) is placed on the bed 86. The bed sheet detector 81A is placed on this. A mattress pad 86b is placed on this, and a cloth 86c (sheets) is placed thereon. The bed sheet detector 81A is one of the load detectors 81. One of the nursing/medical communication devices 110 according to the embodiment is connected to the bed sheet detector 81A.

When the target person 85 is sleeping on the bed 86, the weight (load) of the target person 85 is applied to the bed sheet detector 81A. When the subject 85 leaves the bed 86, the load applied to the bed sheet detector 81A becomes smaller. Or the load disappears. At this time, the first signal Sig1 is supplied from the bed sheet detector 81A to the care/medical communication device 110. The nursing/medical communication device 110 detects the first signal Sig1 and transmits the first wireless signal W1 (see FIG. 1A) based on the first signal Sig1.

As shown in FIG. 2, a floor sheet detector 81B may be provided. The floor sheet detector 81B is placed on the floor near the bed 86, for example. The floor sheet detector 81B may be placed, for example, on the floor of the doorway of the subject's room. The floor seat detector 81B is one of the load detectors 81. One of the nursing/medical communication devices 110 according to the embodiment is connected to the floor sheet detector 81B. For example, when the target person 85 steps on the floor sheet detector 81B, a load is applied to the floor sheet detector 81B. At this time, the first signal Sig1 is supplied from the floor sheet detector 81B to the care/medical communication device 110. The nursing/medical communication device 110 detects the first signal Sig1 and transmits the first wireless signal W1 (see FIG. 1A) based on the first signal Sig1.

As shown in FIG. 2, a bed terminal 82 may be provided. The bed terminal 82 collects data on the bed 86 and its peripheral devices. This data includes, for example, information regarding the angles of the plurality of bottoms included in the bed 86. This data may include, for example, information on the operating state (operating direction, time, etc.) of the drive unit (motor or the like) that drives the plurality of bottoms included in the bed 86. This data may include, for example, information regarding a failure history of the bed 86 and the like. One of the nursing/medical communication devices 110 according to the embodiment is connected to the bed terminal 82. Such data is supplied to the care/medical communication device 110 as the second signal Sig2. The nursing/medical communication device 110 transmits the first wireless signal W1 (see FIG. 1A) based on the second signal Sig2.

The various first wireless signals W1 described above are received by the receiving device 210, and appropriate measures are taken.

Hereinafter, an example of the care/medical communication device 110 will be described.
FIG. 3A to FIG. 3F are schematic views illustrating the care/medical communication device according to the first embodiment.
FIG. 3A is a plan view (top view) viewed from an arrow AR1 in FIG. FIG. 3B is a side view seen from an arrow AR2 in FIG. FIG. 3C is a front view. FIG. 3D is a side view seen from the arrow AR3 in FIG. FIG. 3E is a plan view (rear view) seen from an arrow AR4 in FIG. FIG. 3F is a plan view of the signal line used in the nursing/medical communication device.

As shown in these drawings, the care/medical communication device 110 includes an upper case 38U and a lower case 38L. The wireless module 20, the antenna 60, and the like (see FIG. 1A and the like) are provided between these two cases.

The switching unit 30 is provided on the side surface of the upper case 38U. In this example, the switching unit 30 is a slide switch. A plurality of states of the slide switch correspond to the above-mentioned first state S1 and second state S2. The switching unit 30 may have a “test” state. In the “test” state, for example, a signal is transmitted at a constant cycle. By transmitting this signal, for example, the normal operation of the nursing/medical communication device 110 can be grasped.

In this example, a sensor selection switch 35 and a time selection switch 36 are provided. The sensor selection switch 35 can be set based on, for example, a detector to which the care/medical communication device 110 is connected. For example, when the care/medical communication device 110 is set to the bed sheet detector 81A, the sensor selection switch 35 is set to "bed". On the other hand, when the care/medical communication device 110 is set to the floor sheet detector 81B, the sensor selection switch 35 is set to "floor". In these settings, it is different whether to detect when the load decreases or when the load increases. By switching the sensor selection switch 35, the direction of increase/decrease of the load to be detected can be set.

The time selection switch 36 is used, for example, when the sensor selection switch 35 selects “bed”. For example, the time selection switch 36 can be used to set the time from the acquisition of the data signal DS by the care/medical communication device 110 to the transmission of the first signal W1. In this example, one of the three set times is selected. For example, the first set time is 0 seconds. At this time, a signal (for example, the first wireless signal W1) is transmitted immediately when the load decreases in the bed sheet detector 81A. For example, the second set time is 1 second. At this time, a signal (for example, the first wireless signal W1) is transmitted when the load on the bed sheet detector 81A is continuously reduced for 1 second. For example, the third set time is 3 seconds. At this time, a signal (for example, the first wireless signal W1) is transmitted when the load on the bed sheet detector 81A is continuously reduced for 3 seconds. The three times in the time selection switch 36 can be set depending on, for example, the state of the subject 85. For example, when the target person 85 falls from the bed 86 and cannot get up by himself, the first set time (0 seconds) is adopted, for example. When the target person 85 gets up from the bed 86 and can move in the room, for example, the third set time (3 seconds) is adopted.

As shown in FIGS. 3B and 3E, the first input terminal 10a is provided at a position retracted from the surface of the case. One end of the signal line 10L illustrated in FIG. 3F is connected to such a first input terminal 10a. The other end of the signal line 10L is connected to, for example, the load detection unit 81 (for example, the bed sheet detector 81A or the floor sheet detector 81B). The terminal of the signal line 10L is, for example, a 4-pole mini plug. For example, the first input terminal 10a is a 4-pole minijack.

As shown in FIG. 3E, the terminal of the signal line 10L can be housed in the recess provided in the lower case 38L. This provides a safe and secure connection. The battery 40 is housed inside the battery cover 38B.

As shown in FIG. 3C, in this example, the second input terminal 10b is provided in the lower portion of the upper case 38U. For example, a USB (Universal Serial Bus) cable can be connected to the second input terminal 10b.

In this example, a lamp 37 (for example, an LED element or the like) is provided. The lamp 37 blinks, for example, when transmitting data. The lamp 37 may blink, for example, for a certain period after the signal line 10L is connected. The lamp 37 may blink, for example, when the voltage of the battery 40 drops. The blinking state may be different in these plural states.

Hereinafter, an example of the receiving device 210 will be described.
FIG. 4A to FIG. 4E are schematic views illustrating the receiving device used in the care/medical communication system according to the first embodiment.
FIG. 4A is a plan view (top view) viewed from an arrow AR1 in FIG. FIG. 4B is a side view seen from the arrow AR2 in FIG. FIG. 4C is a front view. FIG. 4D is a side view seen from an arrow AR3 in FIG. FIG. 4E is a plan view (bottom view) seen from the arrow AR4 in FIG.

As shown in these figures, the receiving device 210 includes an upper case 214U and a lower case 214L. The antenna 213, the control unit 218, and the like are provided between these two cases.

In this example, as the notification unit 211, a sound generation unit 211a (for example, a speaker), a display unit 211b, and a vibrator 211c are provided. The sound generation unit 211a generates a sound according to the received content. The display unit 211b (for example, a liquid crystal display device) displays according to the received content. The display unit 211b may emit light. The vibrator 211c vibrates according to the received content.

The control unit 218 controls the operation of the notification unit 211, for example.

In this example, switches 217a to 217d are provided. With the switch 217a, for example, the volume can be adjusted or the presence or absence of sound can be switched. Various settings of the receiving device 210 can be performed by the switch 217b. With the switch 217c, for example, the presence or absence of vibration can be switched. The switch 217d stops sound or vibration at the time of reception.

The operation can be turned on/off by the switch 216 shown in FIG. As shown in FIGS. 4C and 4E, the input terminal 215 is provided in this example. A USB cable, for example, can be connected to the input terminal 215. For example, various settings of the receiving device 210 can be made via a USB cable. The receiving device 210 can drive at least one of a battery and a power supply line. As shown in FIG. 4C, the charging state may be displayed by the lamp 219. The lamp 219 may emit light according to the content of the reception. The lamp 219 may be included in the notification unit 211.

FIG. 5 is a schematic view illustrating a usage state of the nursing/medical communication device according to the first embodiment.
As shown in FIG. 5, in the care/medical communication system 310, a plurality of care/medical communication devices 110 may be used. For example, the number of the nursing/medical communication devices 110 in the first mode operation MO1 is, for example, 1 or more and 80 or less. The number of the nursing/medical communication devices 110 in the second mode operation MO2 is, for example, 1 or more and 5. The number of receiving devices 210 is, for example, 1 or more and 10 or less. For example, when the distance between the care/medical communication device 110 in the first mode operation MO1 and the receiving device 210 is short, the number of the care/medical communication devices 110 in the second mode operation MO2 may be zero. .. The above number is an example, and in the embodiment, the above number can be variously changed.

In the embodiment, the care/medical communication device 110 and the receiving device 210 in the first mode operation MO1 may be paired. As a result, communication congestion can be suppressed.

As described above, in the present embodiment, the data signal DS (see FIG. 1A, etc.) is the detection signal detected by the load detection unit 81 arranged on at least one of the bed 86 and the floor. (First signal Sig1) is included. Thereby, for example, the state of the target person 85 such as wandering can be grasped.

In the embodiment, the data signal DS includes a bed information (second signal Sig2) signal regarding the bed 86. By transmitting the bed information, the states of the target person 85 and the bed 86 can be grasped. For example, the maintenance of the bed 86 becomes easy.

As described above, the care/medical communication system 310 according to the first embodiment includes the care/medical communication device 110 (or the care/medical communication device 110a) and the receiving device 210. The receiving device 210 receives, for example, the first wireless signal W1 transmitted from the care/medical communication device 110 (see FIG. 1A). The notification unit 211 provided in the reception device 210 performs at least one of display, light emission, sound, and vibration notification based on the first wireless signal W1.

The receiving device 210 may receive the relay signal W3 from the care/medical communication device 110, for example. The notification unit 211 notifies at least one of display, light emission, sound, and vibration based on the relay signal W3 (see FIG. 1B). In this case, the care/medical communication system 310 includes a plurality of care/medical communication devices 110 (see FIG. 1B).

The wireless module 20 included in one of the plurality of care/medical communication devices (for example, the care/medical communication device 110a in FIG. 1B) performs the first mode operation MO1. On the other hand, the wireless module 20 included in another one of the plurality of care/medical communication devices (for example, the care/medical communication device 110 of FIG. 1B) performs the second mode operation MO2.

Is.

In the present embodiment, the care/medical communication system 310 may further include a load detection unit 81. The load detection unit 81 is arranged on at least one of the bed 86 and the floor. The data signal DS includes a detection signal detected by the load detection unit 81.

(Second embodiment)
FIG. 6A and FIG. 6B are schematic views illustrating the care/medical communication device and the care/medical communication system according to the second embodiment.
As shown in these drawings, in the care/medical communication system 320, the care/medical communication device 120 according to the embodiment is provided. The care/medical communication device 120 further includes an informing unit 11 in addition to the input unit 10, the wireless module 20, and the switching unit 30. In this example, the control unit 18 is also provided. The input unit 10, the wireless module 20, and the switching unit 30 are the same as those in the care/medical communication device 110, and a description thereof will be omitted.

The notification unit 11 performs at least one of display, light emission, sound, and vibration according to the data signal DS. The notification unit 11 has the same function as the notification unit 211 provided in the reception device 210. The control unit 18 controls the operation of the notification unit 11. The control unit 18 has the same function as the control unit 218 provided in the receiving device 210.

As shown in FIG. 6A, in this example, the switching unit 30 has the already-described third state S3. When the switching unit 30 is in the third state S3, the notification unit 11 performs notification according to the data signal DS. On the other hand, when the switching unit 30 is not in the third state S3 (first state S1 or second state S2), the notification unit 11 does not perform the notification. When the switching unit 30 is in the third state S3, it corresponds to the reception mode.

In the present embodiment, the care/medical communication device 120 can be implemented by switching the reception mode in addition to the detection/transmission mode and the relay mode, for example. When the switching unit 30 is in the third state S3, the notification unit 11 makes a notification.

Such three operation modes can be switched depending on the state of the switching unit 30. It is even more convenient because it can implement three modes of operation. A convenient care/medical communication device and a care/medical communication system can be provided.

When the switching unit 30 is in the third state S3, the wireless module 20 may perform the third mode operation MO3. In the third mode operation MO3, for example, no wireless signal is transmitted. Alternatively, in the third mode operation MO3, for example, a wireless signal (relay signal W3) transmitted from another care/medical communication device in the relay mode may be received. Notification is performed based on the received relay signal.

Alternatively, when the switching unit 30 is in the third state S3, the wireless module 20 may perform the first mode operation MO1 described above. In this case, the nursing/medical communication device 120 functions as a transmitting device while operating as a receiving device.

Alternatively, when the switching unit 30 is in the third state S3, the wireless module 20 may perform the second mode operation MO2 described above. In this case, the nursing/medical communication device 120 functions as a relay device while operating as a receiving device.

As shown in FIG. 6B, in the care and medical communication device 120a according to the present embodiment, the switching unit 30 is in the first state S1 and the first mode operation MO1 is performed. As a result, the first wireless signal W1 is transmitted from the nursing/medical communication device 120a. This first wireless signal W1 is received by another care/medical communication device 120. In the care and medical communication device 120, the switching unit 30 is in the third state S3. In the care/medical communication device 120, notification is performed based on the data signal DS corresponding to the received first wireless signal W1.

FIG. 7 is a schematic diagram illustrating a care/medical communication device and a care/medical communication system according to the second embodiment.
As shown in FIG. 7, in the care/medical communication system 321, a plurality of care/medical communication devices are provided. In the care/medical communication device 120a, the switching unit 30 is in the first state S1, and the first mode operation MO1 (detection/transmission mode) is performed. In the nursing/medical communication device 120b, the switching unit 30 is in the second state S2, and the second mode operation MO2 (relay mode) is performed. In the nursing/medical communication device 120, the third mode operation MO3 (reception mode) is performed. The first wireless signal W1 transmitted from the care/medical communication device 120a becomes a reception signal (second wireless signal W2) in the care/medical communication device 120b. A relay signal W3 is transmitted from the nursing/medical communication device 120b. The nursing/medical communication device 120 receives the relay signal W3. In the care/medical communication device 120, the notification unit 11 gives notification based on the relay signal W3.

In the embodiment, the care/medical communication device operates by switching between three modes, so that more stable communication can be performed.

In the present embodiment, the first mode operation MO1 and the third mode operation MO3 may be switched and implemented, and the second mode operation MO2 may not be implemented.

According to the embodiment, it is possible to provide a care/medical communication device and a care/medical communication system capable of stable communication.
