[0009] Hereinafter, one embodiment for carrying out the system of the present disclosure will be described with reference to the drawings. Note that the contents of the present disclosure merely show one example of an embodiment, and are not limited to the disclosed numerical values ​​and configurations, and include equivalents that can be conceived by a person skilled in the art.

[0010] [1. First embodiment] A bed system including a bed device on which an air mattress is placed is known. The air mattress is controlled so that the internal pressure of the cells constituting the air mattress increases (higher) according to the weight of the user. The internal pressure of the air mattress may also be controlled by the amount of sinking of the air mattress body.

[0011] However, if the hardness of the air mattress is changed uniformly based on the weight of the user, the user will not feel comfortable. The weight and shape of the user vary from part to part, such as the head, shoulders, waist, buttocks, thighs, and feet. Therefore, it is preferable to change the hardness of the air mattress for each part according to the weight and shape of each part, rather than changing the hardness of the air mattress uniformly.

[0012] In addition, if the hardness of each part is adjusted based on the amount of sinking of the air mattress body, a sensor to detect the amount of sinking of the air mattress must be installed under each cell. Therefore, this method requires multiple sensors, which leads to increased costs.

[0013] Therefore, according to the bed system of this embodiment, it is possible to recommend an air mattress hardness arrangement pattern according to the user's attribute information (weight information, height, sex, sleeping position, hardness preference, illness (lower back pain, etc.)) by using the user's attribute information. Also, the bed system of this embodiment is able to adjust the internal pressure of the air mattress based on the recommended content.

[0014] In addition, the bed system of this embodiment allows the arrangement pattern of the air mattress' firmness to be adjusted for each part of the body, such as the head, shoulders, waist, buttocks, thighs, and toes, and recommends the optimal firmness for each part of the body according to its weight and shape.

[0015] In addition, in the bed system of this embodiment, the hardness adjustment for each part is performed based on the user's attribute information, so there is no need to install sensors under each cell, and the hardness adjustment function for each part can be realized while keeping costs down.

[0016] In this specification, the user refers to a person who uses a bed apparatus (mattress), and even a healthy person can be a user as long as he / she is in bed with the bed apparatus (for example, lying on his / her back). That is, the user can be asleep or awake in the bed apparatus. In addition, the bed apparatus can be used not only in the home but also in a hospital where a person is receiving treatment for an illness (for example, a patient) or in a facility where a person is receiving care.

[0017] In addition, in this specification, staff etc. includes those who support the user, such as family members, those who assist the user, such as medical professionals and staff at facilities, and those who are involved with the user.

[0018] [1.1 Overall system description] 1 is an overall view for explaining an outline of a system 1 according to the present embodiment. The system 1 includes one or more bed systems 3.

[0019] In addition, in the system 1, a control device 10, a server device 40, and a terminal device 50, all of which are included in the bed system 3, are connected via a network NW.

[0020] In the bed system 3, an air mattress 20 consisting of a plurality of cells (air cells) is placed on a bed device 30. A user P can lie or sit on the air mattress 20. The air mattress 20 may be covered with a cover, or may be configured together with a polyurethane mattress.

[0021] Each cell of the air mattress 20 is connected to an air supply and exhaust device 15. The air supply and exhaust device 15 can control the internal pressure of each cell by sucking air into and exhausting air from each cell that constitutes the air mattress 20. The air supply and exhaust device 15 is composed of, for example, a pump.

[0022] Moreover, the air supply and exhaust device 15 is connected to the control device 10. The air supply and exhaust device 15 and the control device 10 may be configured integrally or separately.

[0023] The control device 10 is a device that controls the entire bed system 3. The control device 10 may be connected to the bed device 30 and the detection device 35 in addition to the air supply and exhaust device 15.

[0024] That is, the control device 10 can control, for example, the bottom of the bed device 30 by controlling the bed device 30. The control device 10 can realize a back-raising action and a back-lowering action by operating the back bottom, and can realize a knee-raising action and a knee-lowering action by operating the knee bottom.

[0025] Moreover, the control device 10 can detect the load, vibration, and body movement of the user P by connecting to the detection device 35. The detection device 35 may be, for example, a load sensor such as a load cell provided on the housing of the bed device 30. The detection device 35 may also be a load sensor placed under the user P (for example, directly under the user P or between the bed device 30 and the air mattress 20). The detection device 35 can obtain not only the weight of the user P, but also body movement (for example, turning over, etc.), posture (lying, lying on one's back, sitting on the edge, etc.), and biological information (heart rate, breathing, etc.).

[0026] The control device 10 may also obtain the sleep state as the state of the user P by using the detection device 35. Here, the sleep state indicates whether the user is asleep or awake as the state of the user P. When the user P is asleep, the depth of sleep such as non-REM sleep or REM sleep may be determined as the sleep state.

[0027] An operating device and a display device may be further connected to the control device 10. Although not shown in Fig. 1, the system 1 may appropriately include an operating device, a display device, and a communication device as separate devices.

[0028] The bed apparatus 30 has one or more bottoms. The bottoms are composed of a movable back section, a seat section, an upper leg section, a foot section, etc., and the back and legs can be raised by the operation of each bottom. The air mattress 20 is placed on the bottoms.

[0029] The bed apparatus 30 may also include a lifting mechanism. The lifting mechanism can change the height (floor height) of the bottom part of the bed apparatus 30. In this specification, the floor height of the bed apparatus 30 refers to the distance from the floor on which the bed apparatus 30 is placed to the bottom (the bottom when in a horizontal state). The floor height of the bed apparatus 30 may be the distance from the floor to the bottom, or the distance from the floor to the upper frame, or the distance from the floor to the mattress. The floor height of the bed apparatus may be based on the lower frame, rather than the floor.

[0030] Furthermore, the bed apparatus 30 can perform an operation (tilt operation) of tilting the entire bed apparatus 30. The bed apparatus 30 may be a bed apparatus in which none of its parts are movable.

[0031] The server device 40 is connected to the network NW and provides a predetermined service. The server device 40 may be installed by the same business operator, or may be installed by an external business operator. The server device 40 may be configured with one or more distributed devices for each function.

[0032] The terminal device 50 is a device that can be connected to the system 1 via the network NW. For example, it includes general information processing devices such as a smartphone, a portable device such as a tablet, a wearable device, and a personal computer used by the user P or the staff. The terminal device 50 may also be directly connected to the control device 10, the detection device 35, etc. via wireless communication or wired communication.

[0033] In the above-mentioned system 1, the terminal device 50 functions as an information providing device. For example, the terminal device 50 can provide information about the bed system 3 to the user. The information provided to the user includes information about the pressure settings of the cells (cell group) constituting the air mattress 20, and information about the cell setting pattern. Furthermore, the information provided to the user may include, as information about the bed device 30, the state of each bottom, the state of the back-raising and back-lowering operations, and the state of the knee-raising and knee-lowering operations. Furthermore, the information provided to the user may include, as information about the user, information about the user, such as the user's weight, sleeping position, biological information (heart rate, respiratory rate), and body temperature.

[0034] The information providing device may be realized by the control device 10. The control device 10 can display the above-mentioned various information on the display unit 150. That is, the system 1 can provide information to users, staff, etc. by displaying information on any of the devices or sending emails to any of the devices.

[0035] [1.2 Air mattress composition] 2 is a diagram illustrating the configuration of the air mattress 20. The air mattress 20 is configured, for example, by arranging a plurality of cells C10 continuously in the longitudinal direction of the bed apparatus 30. Then, it is covered with a cover to form a mat body.

[0036] Further, an air supply tube is connected to each cell C10 from the air supply / exhaust device 15. The control device 10 controls the air supply / exhaust device 15, so that air is supplied and exhausted from the air supply / exhaust device 15 (for example, a pump).

[0037] Here, the cell C10 is divided into several cell groups, each of which is connected to the air supply and exhaust device 15 by an air blower tube (not shown). As shown in FIG. 2(a), in this embodiment, the cell C10 is divided into the following cell groups.

[0038] Cell group C1: Located near the head of user P Cell group C2: Located near the shoulder of user P Cell group C3: Located near the waist and back of user P Cell group C4: Located near the buttocks of user P Cell group C5: Located near the thighs of user P Cell group C6: Located at the feet of user P

[0039] This is based on the assumption of an average Japanese person's body type (height 172 cm, weight 65 kg). For example, if the air mattress 20 is made up of 23 cells, then, from the side closest to the head of the user P, it will be made up of three cell groups C1, three cell groups C2, three cell groups C3, five cell groups C4, four cell groups C5, and five cell groups C6.

[0040] In the following embodiment, the cell groups of the air mattress 20 are divided into six, but may be divided into three or more cell groups. For example, as shown in Fig. 2(b), the cell groups of the air mattress 20 may be divided into three (cell group C7 located near the head and back, cell group C8 located near the waist and buttocks, and cell group C9 located near the feet). The cell groups of the air mattress 20 may also be divided according to the position of the bottom.

[0041] Generally, the cells included in the cell group are connected to the air supply / exhaust device 15 through the same air blowing tube, and are branched off into the cells included in the cell group, but they may be connected through different tubes. A switching valve may be provided between the air supply / exhaust device 15 and the cell C10 to switch the cell C10 to be supplied or exhausted.

[0042] [1.3 Functional configuration] Next, the functional configuration of this embodiment will be described. Fig. 3 and Fig. 4 show the functional configuration of the control device 10 and the bed device 30. Fig. 4 is a diagram for explaining the relationship between the bottom 32 constituting the bed device 30 and each drive unit. As shown in Fig. 4, the bottom 32 has a back bottom 32a, a waist bottom 32b, a knee bottom 32c, and a foot bottom 32d under the user P. Fig. 5 shows the functional configuration of the server device 40. Fig. 6 shows the functional configuration of the terminal device.

[0043] [1.3.1 Control device and bed device] The control unit 100 is a functional unit for controlling the entire control device 10. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 110, and is composed of one or more control devices (e.g., CPU (Central Processing Unit)). The control unit 100 may also function as a bottom control unit 102, a height control unit 104, a sleeping posture determination unit 106, and a sleeping state acquisition unit 108.

[0044] The bottom control unit 102 controls the drive unit 120 to operate the bottom 32 and perform a back-raising operation and a knee-raising operation. The height control unit 104 also controls the drive unit 120 to control the height of the bed apparatus 30.

[0045] The sleeping posture determination unit 106 determines the sleeping posture of the user (the posture in which the user sleeps on the air mattress 20). The sleeping posture determination unit 106 may determine the sleeping posture based on information acquired by the detection unit 130 from the detection device 35, or may determine the sleeping posture based on information input by the user. The sleeping posture determination unit 106 determines the sleeping posture as, for example, a supine position or a lateral position, but may also determine postures such as a lateral position, a long sitting position, or a sitting position on the edge of the bed. In addition, as a method for determining the sleeping posture of the user, for example, a posture determination method described in JP 2019-098069 A (Name of invention: Posture determination device, Application date: December 7, 2017) can be used. This patent application is incorporated in its entirety by reference.

[0046] The sleep state acquisition unit 108 acquires the sleep state of the user. Here, the sleep state of the user is a state indicating whether the user is awake or asleep. In addition, the sleep state may include the depth of sleep, such as REM sleep or non-REM sleep. The sleep state acquisition unit 108 can acquire the sleep state based on the information acquired from the detection unit 130.

[0047] As a method for determining the sleep state of these users, for example, the sleep state determination methods described in JP 2010-264193 A (title of invention: sleep state determination device, program, and sleep state determination system, filing date: May 18, 2009) and JP 2016-87355 A (title of invention: sleep state determination device, sleep state determination method, and program, filing date: November 11, 2014) can be used. This patent application is incorporated by reference in its entirety.

[0048] The storage unit 110 is a functional unit that stores various programs and various data necessary for the operation of the system 1. The storage unit 110 is configured, for example, with a semiconductor memory, a solid state drive (SSD), a hard disk drive (HDD) which is a magnetic disk device, etc. The storage unit 110 may be a non-transient storage medium or a temporary storage medium.

[0049] The memory required by the control unit 100 during execution may be secured in the storage unit 110, or a storage area may be provided within the control unit 100.

[0050] The memory unit 110 secures an area for a setting table memory area 112 for storing a setting table. The setting table is a pressure table for setting the pressure level (hardness / softness) of the cells (cell group) of the air mattress 20. The control unit 100 controls the supply or exhaust of air to the air supply / exhaust control unit 180 according to the setting table. Note that the setting table may be stored so long as it allows the air supply / exhaust control unit 180 to control the pressure of the cells (cell group). For example, the pressure value may be stored directly, or may be stored after being converted to a predetermined level. In other words, the pressure value includes not only pressure values ​​detectable by a pressure sensor or the like, but also relative pressure values ​​and values ​​converted to a predetermined level.

[0051] The driving unit 120 is a driving device for driving other devices, such as an actuator. That is, the driving unit 120 can operate a bottom, a frame, etc. connected thereto by advancing or retracting a piston rod of the actuator.

[0052] The operation unit 140 accepts operations from a user. For example, the operation unit 140 accepts input from an operation button or via a touch panel. The display unit 150 displays various information to the user. The display unit 150 is configured by, for example, a liquid crystal display or an organic EL panel.

[0053] The notification unit 160 performs a notification operation for the user. The notification unit 160 may output a voice or an alarm sound from a speaker, or output a light from an LED, etc. The communication unit 170 communicates with other devices.

[0054] The communication unit 170 communicates with a network or other devices. For example, the communication unit 170 is an interface that connects to a LAN (Local Area Network) wirelessly or by wire. The communication unit 170 may be configured as a communication module that can connect to a mobile communication network such as LTE / 4G / 5G. The communication unit 170 may be configured by short-range wireless communication (for example, Bluetooth (registered trademark) or the like) for connecting to the terminal device 50.

[0055] The air supply and exhaust control unit 180 controls the air supply and exhaust to the cell (cell group) by controlling the air supply and exhaust device 15. The air supply and exhaust control unit 180 may supply and exhaust air by discharging (positive pressure) and suctioning (negative pressure) the air supply and exhaust device 15 (pump), or may exhaust air by controlling an exhaust valve. The air supply and exhaust control unit 180 may be realized by the control unit 100.

[0056] Here, the operation unit 140, the display unit 150, the notification unit 160, and the communication unit 170 may be provided in the bed system 3 as necessary. In addition, the operation unit 140, the display unit 150, and the notification unit 160 may be integrally formed as an operation remote control.

[0057] For example, the control device 10 may be connected to another terminal device (smartphone) via the communication unit 170. In this case, the operation unit 140, the display unit 150, and the notification unit 160 may be realized by the terminal device (smartphone).

[0058] Next, the relationship between the control unit 100, the driving unit 120, and the load detection unit 130 will be described with reference to FIG.

[0059] The bottom control unit 102 can control the back drive unit 62, the knee drive unit 64, and the head drive unit 66 of the drive unit 120. For example, when a back-raising operation is performed by the user, the bottom control unit 102 controls the back drive unit 62 to perform the back-raising operation.

[0060] Specifically, for example, one end of the back drive unit 62 is rotatably fixed to the frame of the bed device 30, and the other end (the tip of the piston rod) is rotatably fixed to the back bottom 32a via a link mechanism or the like. When the piston rod of the back drive unit 62 advances, it rotates around the waist bottom 32b side of the back bottom 32a, and the head side rises. This realizes the back-raising operation.

[0061] Similarly, when the user performs an operation to raise the knees, the bottom control unit 102 controls the knee driving unit 64 to perform the knee raising motion. When the knee driving unit 64 operates, the knee bottom 32c operates, but the foot bottom 32d may operate in conjunction with the operation.

[0062] That is, when the knee bottom 32c rotates around the waist side and the foot side rises, the knee bottom 32c side of the foot bottom 32d rises and the foot side falls. This makes the knee bottom 32c and foot bottom 32d mountain-shaped, making it possible to properly support the knees and feet of the user.

[0063] In addition, when the back bottom 32 a is divided at the head portion, the bottom on the head side may be operated by the head drive unit 66 .

[0064] When the user operates to raise or lower the height of the bed apparatus 30, the height control unit 104 controls the height drive unit 68. The height control unit 104 adjusts the height of the bed apparatus 30 by controlling the height drive unit 68. That is, the height control unit 104 can raise or lower the bed height. In addition, raising the bed height may be called bed raising, and lowering the bed height may be called bed lowering.

[0065] Here, the height drive unit 68 may be a different drive device (actuator) for the head side and the foot side. By providing different drive devices for the head side and the foot side, the height drive unit 68 can not only change the height of the bed apparatus 30 but also perform tilt control.

[0066] The load detection unit 130 receives a load signal, for example, from the drive unit 120. The load detection unit 130 receives load signals respectively from the back drive unit 62, the knee drive unit 64, the head drive unit 66, and the height drive unit 68. Then, the load detection unit 130 performs a predetermined process on the received load signal, for example, and outputs it to the control unit 100.

[0067] The function of the load detection unit 130 may be provided in each drive unit. In this case, the back drive unit 62, the knee drive unit 64, the head drive unit 66, and the height drive unit 68 output load signals to the control unit 100.

[0068] 4 is an example and may be selected as necessary. For example, the drive unit 120 may include only the back drive unit 62 and the knee drive unit 64. The drive unit 120 may include a drive unit not shown in FIG. 4 (for example, a drive unit for rotating (rolling) the user P).

[0069] Although the load detection unit 130 detects the load signal from the drive unit 120, the load may be detected from another device. For example, a load sensor may be provided between the bottom 32 and the air mattress 20 to detect the load on the air mattress 20. The load signal may also be detected from a load detector such as a load cell provided on the bed frame of the bed device 30.

[0070] [1.3.2 Server device] The configuration of the server device 40 will be described with reference to Fig. 5(a). The control unit 400 is a functional unit for controlling the entire server device 40. The control unit 400 realizes various functions by reading and executing various programs stored in the storage unit 410, and is composed of one or more control devices (e.g., CPU (Central Processing Unit)). The control unit 400 may also function as a recommendation table generation unit 402.

[0071] The recommendation table generating unit 402 generates a recommendation table. The recommendation table is a table used for recommending (recommending) the hardness or softness of the air cell group to the user from the server device 40. The process of generating the recommendation table by the control unit 400 (recommended table generating unit 402) will be described later.

[0072] The storage unit 410 is a functional unit that stores various programs and various data necessary for the operation of the server device 40. The storage unit 410 is configured, for example, with a semiconductor memory, a solid state drive (SSD), a hard disk drive (HDD) which is a magnetic disk device, etc. The storage unit 410 may be a non-transient storage medium or a temporary storage medium.

[0073] The memory required by the control unit 400 during execution may be secured in the storage unit 410, or a storage area may be provided within the control unit 400.

[0074] The memory unit 410 reserves areas for a pressure ratio table memory area 412 for storing a pressure ratio table, a recommendation table memory area 414 for storing a recommendation table, a setting table memory area 416 for storing a setting table, and an attribute information memory area 418 for storing user attributes.

[0075] In this embodiment, the pressure ratio table divides the body parts of the user into cell groups, and stores the pressure ratio for each cell group in the table.

[0076] For example, Fig. 5(b) is a diagram showing an example of a pressure ratio table, which shows the ratio of parts in the case of a standard Japanese adult male.

[0077] For example, if the total is 100%, and the user is in a supine position, the standard pressure ratios are assigned from the foot side as "11," "6," "35," "16," "27," and "5" (assigned so that the total sum is 100%).

[0078] The pressure ratio table may be stored for each posture. The pressure ratio table may be stored in association with gender, symptoms, and the like in addition to height.

[0079] The recommendation table storage area 414 stores a recommendation table to be transmitted to the terminal device 50.

[0080] The setting table storage area 416 stores a setting table to be transmitted to the control device 10. The control unit 400 stores the setting table based on a table selected by the terminal device 50 from among the recommended tables or on setting values ​​input by a user.

[0081] The attribute information storage area 418 stores user attribute information. The user attribute information is information about the user, and includes, for example, the following information:

[0082] User's gender, height, weight User's medical history and condition · Sleeping position of the user The communication unit 470 communicates with a network or other devices. For example, the communication unit 470 is an interface that connects to a LAN (Local Area Network) wirelessly or via a wire. In addition, the communication unit 470 may be configured as a communication module that can connect to a mobile communication network such as LTE / 4G / 5G.

[0083] 1.3.3 Terminal Equipment The configuration of the terminal device 50 will be described with reference to Fig. 6. The control unit 500 is a functional unit for controlling the entire terminal device 50. The control unit 500 realizes various functions by reading and executing various programs stored in the storage unit 510, and is composed of one or more control devices (e.g., CPUs (Central Processing Units)).

[0084] The storage unit 510 is a functional unit that stores various programs and various data necessary for the operation of the terminal device 50. The storage unit 510 is configured, for example, with a semiconductor memory, a solid state drive (SSD), a hard disk drive (HDD) which is a magnetic disk device, etc. The storage unit 510 may be a non-transient storage medium or a temporary storage medium.

[0085] The memory required by the control unit 500 during execution may be secured in the storage unit 510, or a storage area may be provided within the control unit 500.

[0086] The storage unit 510 stores a setting application 512. In addition, the storage unit 510 secures areas for a recommendation table storage area 514 for storing a recommendation table, and a setting table storage area 516 for storing a setting table.

[0087] The setting application 512 is an application executed by the control unit 500 to realize the processing of this embodiment in the terminal device 50. For example, the setting application 512 may be pre-installed in the terminal device 50, or may be downloaded from an external device and installed.

[0088] The recommendation table storage area 514 stores the recommendation table received from the server device 40. Moreover, the setting table storage area 516 stores the setting table to be transmitted to the control device 10 or the server device 40.

[0089] The operation unit 540 accepts operations from the user. For example, the operation unit 540 accepts input from an operation button or via a touch panel. The display unit 550 displays various information to the user. The display unit 550 is configured with, for example, a liquid crystal display or an organic EL panel.

[0090] The communication unit 570 communicates with a network or other devices. For example, the communication unit 570 is an interface that connects to a LAN (local area network) wirelessly or by wire. The communication unit 570 may also be configured as a communication module that can connect to a mobile communication network such as LTE / 4G / 5G. The communication unit 570 may also be configured by short-range wireless communication (e.g., Bluetooth (registered trademark) or the like) for connecting to the control device 10.

[0091] [1.4 Processing flow] Next, the flow of processing in this embodiment will be described.

[0092] [1.4.1 System-wide processing] 7 is a diagram (sequence diagram) for explaining the overall flow of the system 1. First, login processing is executed in the terminal device 50, the server device 40, and the control device 10 (S1002). The login processing performs authentication of users and staff in each device. Furthermore, when the login processing is executed, each device becomes able to obtain necessary information.

[0093] The control device 10 transmits the device information to the server device 40 (S1004). Here, the device information refers to information that can be acquired by the control device 10. The device information that can be acquired by the control device 10 includes, for example, the following information.

[0094] The operating status of the air mattress 20. For example, the installation value of each cell group or cell, the internal pressure value (current value), and the operating status (inflation / contraction status) The operating status of the air supply / exhaust device 15. For example, whether air is being supplied to the cell or exhausted from the cell.

[0095] Operation status of the bed apparatus 30. For example, the back lifting angle, the knee lifting angle, the height of the bed apparatus 30 Information that can be obtained from the detection device 35. For example, the user's weight (load on the bed device 30), body movement, whether the user has turned over in bed, heart rate (heart rate), and respiration (respiratory rate) Note that various timings are possible for the control device 10 to transmit the device information to the server device 40. For example, the control device 10 may transmit the device information to the server device 40 at predetermined time intervals (e.g., every 10 seconds, every minute, every hour, or every day). The control device 10 may also transmit the device information in response to a request from the server device 40. In other words, the device information may be transmitted appropriately at a timing required for processing.

[0096] The terminal device 50 executes an attribute information input process (step S1006). The terminal device 50 transmits the input attribute information to the server device 40 (S1008). The server device 40 executes a recommendation process (S1010). The recommendation process will be described later, but the server device 40 executes the recommendation process based on the attribute information and device information to generate one or more recommendation tables.

[0097] Then, the server device 40 transmits the generated recommendation table to the terminal device 50 as recommendation information (S1012). The terminal device 50 executes a cell setting process based on the recommendation information (S1014). Although details will be described later, the terminal device 50 determines a desired setting from among the recommendation tables included in the recommendation information. Then, the terminal device 50 transmits a setting table based on the determined setting as setting information to the server device 40 (S1016) and transmits it to the terminal device 50 (S1018).

[0098] 7, the terminal device 50 transmits the setting information to both the server device 40 and the terminal device 50, but the setting information may be transmitted to either one of them. Also, the terminal device 50 may transmit the setting information to the server device 40, and the server device 40 may transmit the setting information to the control device 10.

[0099] The control device 10 executes a cell control process based on the received setting information (S1020). That is, the control device 10 controls the supply or exhaust of air to each cell (cell group) so that the set value is set to the setting value included in the setting table included in the setting information. As a result, each cell (cell group) is controlled so that the internal pressure is set to the set value.

[0100] Also, the cells may be controlled by the user. For example, based on the recommendation information, the display unit 550 of the terminal device 50 displays patterns included in the recommendation table. The terminal device 50 displays the settings of the cell group based on the attribute information and the device information as a plurality of patterns on the display unit 550. The user can set the setting values ​​for the cell group via the operation unit 140 of the control device 10 while checking the setting values ​​displayed on the display unit 550. This allows the user to easily set the setting values ​​for the cells for each part.

[0101] [1.4.2 Recommendation Processing] The recommendation process executed in the system 1 will be described with reference to Fig. 8. First, the control unit 400 of the server device 40 acquires attribute information (step S102). For example, the control unit 400 may acquire attribute information input by the terminal device 50, or may acquire the user's attribute information from an external management server (for example, an electronic medical record server). In addition, the attribute information may be input by the user himself / herself, or by a staff member or the like.

[0102] Next, the control unit 400 of the server device 40 acquires the device information (step S104). The control unit 400 may acquire the device information as necessary. Therefore, the control unit 400 does not need to acquire the device information. Below, a case will be described in which the control unit 400 acquires the weight, sex, and sleeping position of the user as attribute information in the process of FIG. 8. The attribute information may be the weight of the user acquired from the detection device 35, or may be a value input by the user, staff, or the like.

[0103] Next, the control unit 400 generates a recommendation table for each user's posture. Specifically, the user's posture is first determined (step S106). Here, the user's posture may be determined by input from the user. That is, the user inputs the posture when going to sleep through the terminal device 50. The user's sleeping posture may also be determined by the sleeping posture determination unit 106 of the control device 10. The server device 40 acquires the user's sleeping posture included in the device information transmitted by the control device 10 and determines it as the user's posture.

[0104] When the control unit 400 determines that the user is in the supine position, it calculates the pressure ratio for each part of the user (step S106; supine position -> step S108). That is, the control unit 400 calculates the weight of each part by referring to the weight included in the acquired attribute information and the pressure ratio table.

[0105] Fig. 9(a) is a diagram showing an example of a pressure ratio table. The pressure ratio table shows the pressure ratio for each posture. Since the posture of the user is "supine position", the control unit 400 extracts the pressure ratio table for "supine position" from the pressure ratio table shown in Fig. 5(b).

[0106] Furthermore, if the user's weight is acquired as "65 kg" from the attribute information, the control unit 400 calculates the weight of each part based on the pressure ratio table (FIG. 9(b)). For example, the weight of the feet is calculated as 65 kg x 11 / 100 ≒ 7 kg, and the weight of the buttocks is calculated as 65 kg x 35 / 100 ≒ 23 kg.

[0107] Next, the control unit 400 generates a recommendation table for the supine position (step S110). Specifically, the control unit 400 sets a hardness level correlated to the weight calculated for each part. For example, the control unit 400 sets a predetermined level value, such as a set value of "1" when the pressure value in the cell is 0.5 kPa to 1 Kpa, and a set value of "2" when the pressure value is 1 to 1.5 Kpa. The control unit 400 generates a recommendation table that serves as a standard by determining set values ​​for all parts. In addition, the level may be converted into a level based on the weight of the cell (cell group) as described above, or may be converted into a level corresponding to the internal pressure value of the cell.

[0108] The control unit 400 generates a reference pattern, and then generates multiple patterns by increasing (or decreasing) a certain value. For example, a pattern (normal) that is two levels harder than the reference pattern (soft) and a pattern (hard) that is two levels harder are generated. The number of patterns may be generated in further stages. For example, five levels may be generated, such as "soft," "slightly soft," "normal," "slightly hard," and "hard." The number of patterns may also be generated in numerical stages, from "weak" to "strong." For example, the weakest level may be "1" and the strongest level may be "20," and the patterns may be expressed in 20 stages.

[0109] For example, when the setting for a foot part is "2," this is the setting value for "soft." Therefore, the control unit 400 generates a pattern of "4," which is two steps higher, as "normal," and a pattern of "6," which is two steps higher.

[0110] The control unit 400 generates a recommendation table by collating a plurality of patterns in this manner. Note that the control unit 400 may change the generated recommendation table according to the user's preference.

[0111] For example, the user may change the setting value for the head area if the setting feels strange as is. As shown in FIG. 9(c), the setting value for the head area may change from "4" to "7" to "10" differently from the other areas. The change in the setting value for some areas may be arbitrarily changed by the user or may be predetermined.

[0112] Similarly, when the user's posture is the lateral position (step S106; lateral position), the control unit 400 reads out the pressure ratio table corresponding to the lateral position and calculates the pressure ratio for each part (step S112). Also, the control unit 400 generates a recommendation table for the lateral position (step S114).

[0113] Next, the terminal device 50 determines a table to be actually used from among the recommended tables (step S116). That is, the server device 40 (control unit 400) transmits to the terminal device 50 the recommended table including the multiple patterns generated in step S110 or step S114.

[0114] The terminal device 50 (control unit 500) displays the recommended setting values ​​on the display unit 550 based on the received recommendation table. Then, when one pattern is selected by the user, the terminal device 50 determines the setting table.

[0115] FIG. 9D is a diagram showing a policy when the recommendation table generating unit 402 generates patterns to be included in the recommendation table.

[0116] For example, when the user's attribute is "male" and the sleeping position is "supine", the recommendation table generating unit 402 generates a recommendation table such that the cell corresponding to the buttocks is made firm.

[0117] Furthermore, when the user's attribute is "male" and the sleeping position is "lateral position", the recommendation table generating unit 402 generates a recommendation table such that the cells corresponding to "shoulders" and "buttocks" are softened.

[0118] Furthermore, when the user's attribute is "female" and the sleeping position is "lateral position", the recommendation table generating unit 402 generates a recommendation table to make the "shoulders" softer and the "buttocks" softer. Note that when the user's attribute is "female" and the sleeping position is "supine position", no particular change is required.

[0119] For example, if Fig. 9(c) is a recommendation table for a female in the supine position, Fig. 9(e) is a recommendation table for a male in the supine position. Compared to Fig. 9(c), Fig. 9(e) shows that the buttocks are "+1", that is, the buttocks are stiff.

[0120] Further, a different policy may be applied. For example, in the case of a woman, a separate arrangement pattern for a pregnant woman may be generated since the weight ratio and the shape of the body change depending on the age of the woman. Also, a different policy may be applied depending on the illness. For example, for a person with a history of lower back pain, an arrangement pattern may be generated in which the buttocks are made harder (for example, made harder by 1 to 2 stages).

[0121] 10 is an example of a display screen W100 displayed on the display unit 550 of the terminal device 50. The display screen W100 displays fields into which attribute information can be input. For example, there are provided an area R102 into which the user's gender can be input, an area R104 into which the user's weight can be input, and an area R106 into which the user's sleeping position can be input, as the user's attribute information.

[0122] Furthermore, the display screen W100 displays current setting values ​​in an area R110, and a recommendation table in an area R120. As shown in the area R110, the setting values ​​of each cell group are displayed.

[0123] In Fig. 10, three levels of recommended arrangement patterns, "soft", "normal", and "hard", are displayed in conjunction with the above-mentioned processing. However, the control unit 500 may display a plurality of levels of recommended arrangement patterns. For example, arrangement patterns may be generated and displayed by dividing the levels into "soft", "slightly soft", "normal", "slightly hard", and "hard".

[0124] Here, the user can change the setting value of each cell group. For example, when the cell group B100 is selected, the cell value corresponding to the cell group B100 may be changed.

[0125] Furthermore, the user can select one pattern from among the patterns included in the recommendation table displayed in the area R120. The settings of the pattern selected by the user here may be used as a setting table.

[0126] That is, the user can change the setting value of each cell group by referring to the settings displayed on the display screen W100 and operating the operation unit 140. Also, the setting value of each cell group may be automatically changed to the selected pattern by transmitting a setting table from the terminal device 50 to the control device 10.

[0127] In this case, the control device 10 controls the internal pressure to the set value by supplying or exhausting air to the cell (cell group) so that the internal pressure becomes the internal pressure of the setting table. This allows the user to set the firmness of the air mattress 20 as desired.

[0128] The number of setting values ​​recommended by the terminal device 50 may be one. For example, the area R130 on the display screen W110 in Fig. 11 allows the user to input the hardness of the air mattress as attribute information.

[0129] That is, the terminal device 50 displays recommended setting values ​​in area R132 corresponding to the user's attributes input in area R102, the user's weight input in area R104, the user's sleeping posture input in area R106, and the firmness of the air mattress 20 desired by the user input in area R108.

[0130] This allows the user to set the setting values ​​of the cell group of the air mattress 20 based on the setting values ​​displayed in area R132. Also, this may be transmitted as setting information from the terminal device 50 to the control device 10. The control device 10 controls the air supply and exhaust device 15 based on the setting table included in the received setting information, and controls the supply and exhaust of air so that the internal pressure of the connected cells becomes a predetermined pressure.

[0131] The process flow explained in Fig. 8 has been explained for the entire system 1, but may be executed by a single device as necessary. For example, the process flow explained in Fig. 8 may be executed entirely by the control device 10, or entirely by the terminal device 50. In this case, each device may receive necessary information via a communication unit as necessary.

[0132] [2. Second embodiment] Next, a second embodiment will be described. In addition to the first embodiment, the second embodiment is an embodiment in which the setting table changes in response to a change in the user's posture. In addition, in the description of this embodiment, in principle, only the differences from the first embodiment will be described, and the description of the common parts will be omitted.

[0133] The process flow in FIG. 12 is a diagram in which the process flow in FIG. 8 is replaced. In the process flow in FIG. 12, the process from step S102 to step S118 is the same as in FIG. 8. That is, when the process from step S102 to step S118 in FIG. 12 is executed, a recommendation table is generated based on attribute information and / or device information and the user's posture. Then, the control unit 500 determines one pattern from the recommendation table as a setting table. Based on the determined setting table, the control unit 100 controls the internal pressure to achieve the setting (step S118).

[0134] Here, when the sleeping posture determining unit 106 detects that the user's posture has changed (step S202; Yes), the control unit 100 selects a setting table according to the posture (step S204).

[0135] Here, the control unit 100 has received in advance a recommendation table for a corresponding posture (for example, the supine position and the lateral position in this embodiment) from the server device 40. Then, when the control unit 100 detects that there has been a change in posture (step S202; Yes), the control unit 100 selects a recommendation table corresponding to the posture as a setting table (step S204).

[0136] Then, when the control unit 100 detects that the setting table has been updated, it controls the internal pressure of the cell so that it becomes the set value (step S206). This process is repeatedly executed until the operation is completed (step S208; No → step S202).

[0137] In this way, according to this embodiment, even after the user has gone to sleep, it is possible to control the mattress to correspond to an appropriate sleeping posture as the user's posture changes.

[0138] [3. Third embodiment] Next, a third embodiment will be described. The third embodiment is an embodiment that cooperates with the bed apparatus 30. In addition, in the description of this embodiment, in principle, only the differences from the first embodiment will be described, and the description of the common parts will be omitted.

[0139] First, the control unit 400 judges whether the device state is a specific state (step S302). Here, the control unit 400 acquires the state of the bed apparatus 30 as the device information. The state of the bed apparatus 30 is, for example, the back-raising angle (back angle). The specific state means that the device state is in a specific state. Here, the specific state means, for example, that the back-raising angle is equal to or greater than a specified angle (for example, equal to or greater than 15 degrees, preferably equal to or greater than 30 degrees).

[0140] Then, if there is a user attribute corresponding to the specific state, the control unit 400 updates the setting table (step S304; Yes → step S306). For example, if the user attribute includes a disease of lower back pain, the setting of the cell group corresponding to the buttocks (for example, cell group C4 in FIG. 2(a)) is increased by one to two steps from the normal setting. This reduces the burden on the lower back compared to normal.

[0141] Although the setting table is updated in step S306, the recommendation table may be updated instead.

[0142] Also, in steps S302 to S306, the setting table and the recommendation table are updated by the terminal device 50, but the control device 10 may change the cell setting each time.

[0143] For example, when the control unit 100 detects that the back-raising angle of the bed device 30 has reached a specified angle or more, the control unit 100 may refer to the attribute information and, if the user has lower back pain, make the cell group corresponding to the buttocks harder than usual.

[0144] Furthermore, when the control unit 100 acquires from the attribute information and the device information that the user's posture is edge-sitting, it may maximize the hardness of the cell group corresponding to the buttocks to facilitate getting out of bed. Furthermore, when the user's state returns to the "lying in bed" state, the control unit 100 may return the hardness of the cell group corresponding to the buttocks to the original hardness.

[0145] In this way, according to this embodiment, it is possible to change and generate the setting table and recommendation table based on the attribute information and device information.

[0146] [4. Fourth embodiment] Next, a fourth embodiment will be described. The fourth embodiment is an embodiment in which the expansion and contraction of the cells is controlled to facilitate breathing based on changes in the user's breathing rate, etc. In addition, in the description of this embodiment, in principle, only the differences from the first embodiment will be described, and the description of the common parts will be omitted.

[0147] In the fourth embodiment, the control unit 100 of the control device 10 executes the process of Fig. 14. Note that the terminal device 50 or the server device 40 may execute the process and transmit a control signal to the control device 10.

[0148] First, the control unit 100 judges whether the breathing rate of the user is decreased (step S402). The control unit 100 detects the breathing rate of the user from the detection unit 130 or the detection device 35. Then, when it is judged that the breathing rate per predetermined time is decreased below a specified number, the control unit 100 controls the internal pressure of the cell group (step S402; Yes → step S404). For example, in this embodiment, the control unit 100 makes the hardness of the cell group located at a position corresponding to the head softer than the current setting. Also, the control unit 100 makes the hardness of the cell group located at a position corresponding to the shoulder harder than the current setting (step S404). That is, the control unit 100 compares the hardness of the cell group located at the head and the cell group located at the shoulder, and controls the hardness of the cell group located at the shoulder to be harder than the cell group located at the head. By controlling in this way, the user's chin is turned up, the airway of the throat is secured, and breathing can be promoted.

[0149] After that, the control unit 100 makes the hardness of the cell group located at the position corresponding to the buttocks harder than the current setting. The control unit 100 makes the hardness of the cell group located at the position corresponding to the shoulders softer than the current setting. This induces the user to turn over in sleep, and the apnea state is resolved.

[0150] [5. Fifth Embodiment] Next, a fifth embodiment will be described. The fifth embodiment is an embodiment in which the user is induced to wake up when it is time for the user to wake up, and the expansion and contraction of the cell is controlled when the user wakes up. In this embodiment, in principle, only the differences from the first embodiment will be described, and the common parts will be omitted. In this embodiment, the control device 10 will be described as executing the process, but the terminal device 50 may execute the necessary processes.

[0151] FIG. 15 is a diagram for explaining the processing of this embodiment. The control unit 100 judges whether the current time is within the planned wake-up time zone while the user is asleep (step S502). Here, the control unit 100 acquires the planned wake-up time zone from information about daily sleep managed by the server device 40 as a sleep diary, for example, as a method for acquiring the planned wake-up time zone. The control unit 100 may also acquire the planned wake-up time zone input by the user. The user may also input the wake-up time zone when inputting attribute information in the terminal device 50.

[0152] Next, when the current time is within the planned wake-up time zone, the control unit 100 adjusts the internal pressure of the cells upon detecting the user's REM sleep (step S504; Yes -> step S506). For example, the control unit 100 supplies and exhausts air to the cells so that the group of cells corresponding to the head is the hardest and the group of cells corresponding to the feet is the softest. In other words, the control unit 100 controls the internal pressure of the cells so that the cells become softer in stages from the head side to the foot side.

[0153] Also, the control unit 100 may control the internal pressure of the cells more finely. For example, the control unit 100 first sets the cells of the feet and thighs to the hardest hardness. Next, the control unit 100 sets the cells of the feet and thighs to the softest hardness, and the cells of the buttocks, waist and back to the hardest hardness. Then, the control unit 100 sets the cells of the buttocks, waist and back to the softest hardness, and the cells of the shoulders and head to the hardest hardness.

[0154] In this way, the control unit 100 can induce the user to wake up by moving the user's body by changing the hardness of each part.

[0155] Furthermore, when the control unit 100 is linked with the bed device 30, it may raise the back angle to a specified angle (step S508; Yes → step S510). Here, the control unit 100 may operate the process of adjusting the internal pressure of the cell (step S506) and the process of raising the back angle to a specified angle (step S510) in parallel or at any time. The back angle is preferably raised by about 5 degrees to 30 degrees, and more preferably up to 10 degrees. The specified angle may be set by the user himself.

[0156] [6. Sixth Embodiment] Next, a sixth embodiment will be described. The sixth embodiment is an embodiment in which the expansion and contraction of cells is controlled according to changes in the user's sleep state. In this embodiment, only the differences from the first embodiment will be described in principle, and the common parts will be omitted. In this embodiment, the control device 10 will be described as executing the process, but the terminal device 50 may execute the necessary processes.

[0157] 16 is a diagram for explaining the processing of this embodiment. The control unit 100 detects a change in the depth of sleep of the user (step S602; Yes). That is, the sleep state acquisition unit 108 acquires the depth of sleep (level of sleep) based on the body movements of the user acquired from the detection unit 130 or the detection device 35. Then, the control unit 100 detects the timing at which the depth of sleep (level of sleep) acquired by the sleep state acquisition unit 108 switches between REM sleep / non-REM sleep.

[0158] When the sleep depth has changed, the control unit 100 controls the internal pressure of the cells (step S604). For example, the control unit 100 controls the supply of air to the cells in the buttocks to make the cells harder, or controls the exhaust of air from the cells in the shoulders to make the cells softer. In this way, the cell hardness changes, resulting in a setting that induces the user to turn over in sleep or a setting that makes it easier to turn over.

[0159] If the control unit 100 detects a body movement (i.e., detects the user turning over), it may return the internal pressure of the cell to the state before step S504 (step S606; Yes → step S610). Even if the control unit 100 does not detect a body movement, it may return the internal pressure of the cell to the state before step S504 if a specified time has elapsed (step S606; No → step S608; Yes → step S610).

[0160] Although the number of times of turning over varies from person to person, it is said that it is preferable to turn over a predetermined number of times during the night. Here, the sleep depth has been simply used as an example, but for example, the number of times of turning over when the sleep score is high may be compared with the number of times of turning over currently (while asleep), and turning over may be induced if the number of times of turning over is equal to or less than a threshold (if it is low). As a result, if the number of turns over is small, force continues to be applied to a part of the body, which places a burden on the body. Furthermore, if the user turns over little, the muscles around the waist will become stiff and the back pain will worsen as the user continues to maintain the same posture under a load. This embodiment makes it possible to prevent symptoms such as back pain from occurring by inducing turning over.

[0161] [7. Seventh embodiment] Next, the seventh embodiment will be described. The seventh embodiment is an embodiment in which the user can adjust the firmness of the cells according to the discomfort. In this embodiment, in principle, only the differences from the first embodiment will be described, and the common parts will be omitted.

[0162] 17 shows a process executed by the control unit 100 or the control unit 500 when the setting level of a cell in the setting table is manually changed when the user is approaching bedtime. Note that, although the case where the process is executed by the terminal device 50 will be described below, the process may be executed by the control device 10.

[0163] The bedtime determined by the control unit 500 may be a time (time period) calculated as an average bedtime from data of sleep states accumulated for a certain period of time or data managed as a sleep diary. Alternatively, the user may input that it is time to go to bed and the control unit 500 may use this. Alternatively, instead of the bedtime, the time when the user goes to bed based on the terminal device 50 may be used.

[0164] Here, when there is an operation to change the setting of the cell group (step S702; Yes), the control unit 500 changes the setting level of the cell group (cell) (step S704). Here, the setting level of the cell group (cell) may be changed by, for example, increasing / decreasing buttons such as "+1" and "-1", or by displaying buttons such as "soft" and "hard".

[0165] Next, the control unit 500 detects that the user has experienced "discomfort" (step S706). For example, the control unit 500 may detect that there has been a sense of discomfort when an operation that caused discomfort is received from the user (step S706). The control unit 500 may display a "discomfort" button on the display unit 550, or may allow the user to input that there has been a sense of discomfort by a specific operation (e.g., swipe, double tap, etc.).

[0166] Next, when the control unit 500 detects that the user felt discomfort (step S706; Yes), it prompts the user to select the part where the discomfort was felt (step S708). Then, the control unit 500 transmits the input attribute information (including the selected part), the acquired device information, and the changed setting value (or setting table) to the server device 40. Note that the attribute information may be linked to information on the manual operation history and data on the part selected when the discomfort was felt.

[0167] As a result, the server device 40 stores, as dictionary data, the parts, operations thereof, and setting values ​​selected when one or more users feel discomfort.

[0168] In step S706, the sense of incongruity is detected by an operation from the user. However, the control unit 100 (control unit 400, control unit 500) may detect the sense of incongruity.

[0169] For example, the control unit 100 may detect that the user is feeling uncomfortable if the number of body movements detected by the detection unit 130 or the detection device 35 (the number of times turning over is detected) exceeds a specified number or is higher than the average number for an individual.

[0170] When the control unit 100 detects that the user feels something is wrong, the control unit 100 may ask the user whether or not the user feels something is wrong. For example, a pop-up message may be displayed asking, "Did you feel something is wrong?"

[0171] Also, in the above-mentioned process flow, step S706 may be executed first. For example, when the setting table is updated by the user, if the number of body movements detected (the number of times turning over is detected) is equal to or greater than a specified number or is greater than the average number of times for an individual, it may be determined that the setting is an operation that caused discomfort.

[0172] Fig. 18 is a diagram replacing Fig. 8 of the first embodiment. Here, the control unit 100 reads out the setting table and executes processing such as displaying the contents of the setting table and controlling the internal pressure of the cell based on the setting table (step S118).

[0173] Here, if the user performs an operation to indicate "uncomfortable feeling" (step S752; Yes), the control unit 100 (or control unit 500) prompts the user to select a region (step S754).

[0174] When the user selects a part that is considered to be uncomfortable (step S754), the control device 10 updates the setting table in accordance with the selected discomfort (step S756). That is, by inquiring of the server device 40, the control device 10 refers to the dictionary data based on the current attribute information, device information, and the selected part, and acquires an appropriate setting value (setting level).

[0175] The dictionary data accumulated at this time may be stored in the server device 40, the terminal device 50, or the control device 10.

[0176] Further, for convenience of explanation, the operations that cause discomfort are described in the flowchart as sequential processing, but the order of processing may be changed as appropriate, or the operations may be changed.

[0177] 18, if an operation that gives an uncomfortable feeling is performed before the setting table is determined, the setting table may be updated at this point in response to the uncomfortable feeling. For example, steps S752 to S756 may be executed after step S110. Then, the process may be executed from step S116.

[0178] [8. Eighth embodiment] Next, an eighth embodiment will be described. The eighth embodiment is an embodiment in which the expansion and contraction of the cell is controlled to induce the user to turn over when the user is in the same position for a certain period of time. In this embodiment, only the differences from the first embodiment will be described in principle, and the common parts will be omitted. In this embodiment, the case where the control device 10 executes the process will be described, but the terminal device 50 may also execute the process.

[0179] 19 is a flow chart for explaining the processing of this embodiment. This embodiment is processing executed when the control unit 100 controls the operation of the air mattress 20.

[0180] The control unit 100 detects the body movement of the user (step S802). The control unit 100 may detect the body movement from the detection unit 130 or the detection device 35, or may detect the body movement from a change in the internal pressure of the cell.

[0181] If the patient remains in the same posture for a specified time (for example, 5 minutes, 10 minutes, 20 minutes, etc. while sleeping) without changing posture (step S804; Yes), the control unit 100 controls the internal pressure of the cell by supplying and exhausting air to the cell (step S806).

[0182] The control unit 100 controls the internal pressure of the cells to, for example, make the buttocks harder and the shoulders softer, thereby inducing the user to turn over in sleep.

[0183] In this way, according to this embodiment, if a certain period of time has elapsed during which the user's body movements do not exceed the threshold, it is assumed that the user is continuing to maintain the same posture, and the user is induced to turn over.

[0184] [9. Ninth Embodiment] Next, a ninth embodiment will be described. The ninth embodiment is an embodiment that realizes a massage function by controlling the expansion and contraction of cells. In addition, in the description of this embodiment, in principle, only the differences from the first embodiment will be described, and the description of the common parts will be omitted.

[0185] That is, the control unit 100 changes the internal pressure of the cells as needed depending on the part input by the user. For example, when relieving swelling in the user's legs (when the specified part is the thighs), the control unit 100 makes the cells from the feet to the thighs harder and softens the cells from the buttocks to the head, causing the feet to the thighs to be slightly lifted. This relieves the swelling of the user. At this time, the hardness of the mattress may be returned to its original state after a certain period of time has passed.

[0186] Furthermore, when stretching the body, such as to relieve tension in the lower back, the control unit 100 may set the lower back to the hardest hardness and the other parts to the softest hardness. This causes the user's entire body to lean back, allowing the user to stretch. In this case, the mattress may be returned to its original hardness after a certain period of time has passed.

[0187] 20 is an example of the operation screen W800 of this embodiment. The operation screen W800 displays "Please select the part you want to be massaged," and the parts to be massaged are displayed around the human body diagram.

[0188] Here, for example, when the "foot" displayed in area R800 is selected by the user as the target part, control unit 100 executes a massage corresponding to the foot part (expansion / contraction processing corresponding to the foot and thigh).

[0189] In this way, according to this embodiment, it is possible to massage the user using only the mattress, and therefore the mattress of this embodiment can appropriately relieve swelling and the like of the user.

[0190] [10. Tenth Embodiment] Next, a tenth embodiment will be described. The tenth embodiment is an embodiment that realizes a nap mode. In the description of this embodiment, in principle, only the differences from the first and fifth embodiments will be described, and the description of the common parts will be omitted.

[0191] For example, in the fifth embodiment, the internal pressure of the cell is controlled in REM sleep and non-REM sleep. In this embodiment, a nap mode is provided.

[0192] For example, when the user starts the nap mode by pressing a "nap mode" switch provided on the terminal device 50 or the operation unit 140 of the control device 10, a timer starts.

[0193] In the nap mode, the hardness of the entire air mattress 20 (the hardness of the cells) is made harder than the hardness at which the user normally sleeps, so that the user does not fall into too deep a sleep.

[0194] Also, after a specified time has elapsed (e.g., 15 to 30 minutes) since pressing "nap mode," the cells in the head area may be set to the hardest, and the cells in the foot area to the softest (i.e., from head to foot, the cells are set to the hardest to the softest). In other words, by creating an inclination in the hardness of the cells on the air mattress 20, it is possible to induce waking up.

[0195] In addition, when linked with the bed apparatus 30, the control unit 100 may raise the back angle of the bed apparatus 30 to a specified angle (for example, 10 degrees). In addition, the control unit 100 may simultaneously perform control to raise the back angle of the bed and control of the internal pressure of the cell.

[0196] [11. Eleventh embodiment] Next, an eleventh embodiment will be described. The eleventh embodiment is an embodiment in which the internal pressure of the cell is controlled according to the number of turns. In addition, in the description of this embodiment, in principle, only the differences from the first embodiment will be described, and the description of the common parts will be omitted.

[0197] Fig. 21 is a diagram for explaining the eleventh embodiment. First, when the control unit 100 detects a body movement of the user, it increments the number of body movements n by one (step S902; Yes -> step S904). That is, the control unit 100 judges whether the user is moving or not based on the detection results of the detection unit 130 and the detection device 35. Then, when the user is moving, the control unit 100 judges that there has been a body movement, and adds one to the number of body movements.

[0198] Next, when the specified time has elapsed (step S906; Yes), the control unit 100 determines whether the number of body movements n of the user is less than the specified number (step S908). The specified time is, for example, 30 minutes or 1 hour while the user is asleep. This specified time may be set in advance or may be set by the user or a staff member.

[0199] Here, if the number of times n of the user's body movements is less than the specified number of times, the control unit 100 controls the internal pressure of the cell (step S908; Yes→step S910).

[0200] In other words, if the number of body movements within a specified time is less than a specified value, it is determined that the hardness of the mattress is not suitable for the body (is too soft). Therefore, the control unit 100 makes the hardness of the buttocks harder. By making the hardness of the buttocks harder, the user is induced to turn over in sleep, which increases the number of body movements.

[0201] The control unit 100 may adjust the firmness at regular intervals until the number of body movements within a specified time period reaches or exceeds a specified value. This is because a small number of turns over in bed can lead to lower back pain for the user.

[0202] In addition, in combination with the sleep score, the control unit 100 may compare the number of times the user turns over when their sleep score is high with the current number of times they turn over (when asleep), and if the current number of times they turn over is low, may induce turning over by stiffening the buttocks or softening the shoulders.

[0203] Furthermore, the control unit 100 may obtain the average number of turns in sleep of people with high sleep scores among people with similar attribute information, and reflect this in the recommendation table.

[0204] [12. Twelfth Embodiment] Next, a twelfth embodiment will be described. The twelfth embodiment is an embodiment related to the direction in which the user sleeps on the air mattress 20 and the internal pressure control of the cells. In addition, in the description of this embodiment, in principle, only the differences from the first embodiment will be described, and the description of the common parts will be omitted.

[0205] 22 is a diagram for explaining the twelfth embodiment. The control unit 100 supplies air to the cells more than usual (step S952). After that, the control unit 100 sequentially exhausts air from the cells (step S954).

[0206] At this time, the control unit 100 exhausts air from the head, shoulders, waist, buttocks, thighs, and legs in that order, starting from the head, and measures the time it takes for the air to escape. Note that the time it takes for the air to escape does not necessarily mean the time it takes for the air to escape completely, but rather, it may be enough to allow the air to escape to a specified internal pressure, for example.

[0207] Here, if the control unit 100 determines that the user is not in a correct posture (step S956; Yes), it executes a process of notifying the user of that effect (step S958). That is, when the user sleeps with the head and feet facing backwards, there is a difference in the time it takes for the air to escape, so if the time difference is equal to or greater than a specified value, the control unit 100 determines that the user is sleeping with the head and feet facing backwards.

[0208] In this case, the time it takes for the air to escape when the person is sleeping in the correct position may be a fixed value determined in advance, or may be stored through a calibration process or the like.

[0209] Furthermore, when the control unit 100 is controlling the operation of the air mattress 20 or the bed apparatus 30, the control unit 100 may stop the control.

[0210] [13. Effects] According to each of the above-mentioned embodiments, it is possible to recommend a hardness arrangement pattern based on the user's attribute information (one or more of the following information: weight, height, sex, sleeping position, hardness preference, and illness (lower back pain, etc.)). This makes it possible to provide an air mattress with the optimal hardness for the user.

[0211] For example, if a user has lower back pain (if "has lower back pain" is entered as attribute information), the strain on the lower back can be reduced by making the internal pressure in the lower back area harder.

[0212] Also, for example, if the user is sleeping in a lateral position, it is possible to recommend a firmness arrangement pattern that takes into account the weight and shape of each part of the body by softening the firmness of only some parts, such as the shoulders and buttocks.

[0213] The adjustment of hardness, taking into account the weight and shape of each part of the body, is done based on the input attribute information, so there is no need to use sensors for each cell, making it possible to achieve functionality while keeping costs down.

[0214] [14. Modifications] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and designs that do not deviate from the gist of the present invention are also included in the scope of the claims.

[0215] In addition, the programs that run on each device in the embodiments are programs that control the CPU and the like (programs that make a computer function) so as to realize the functions of the above-described embodiments. Information handled by these devices is temporarily stored in a temporary storage device (e.g., RAM) during processing, and is then stored in various types of ROM, HDD, and SSD storage devices, and is read, modified, and written by the CPU as necessary.

[0216] In addition, when distributing the program on the market, the program can be stored in a portable recording medium and distributed, or transferred to a server computer connected via a network such as the Internet. In this case, the storage device of the server computer is of course included in the present invention.

[0217] By installing an application capable of implementing the functions implemented by the control unit 100 on the smartphone, it is possible to implement the system of the above-described embodiment on the smartphone.

[0218] Although each embodiment is described separately, they can be combined and implemented as necessary. The functions executed by the control device 10, the terminal device 50, and the server device 40 can also be realized by other devices to the extent that there is no contradiction. For example, among the functions described in the present embodiment, the functions executed by the server device 40 and the functions executed by the terminal device 50 can be realized by the control device 10 alone.
