[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the embodiment described below is one embodiment of the present disclosure, and the contents of the present disclosure should not be interpreted as being limited based on the following description.

[0011] Generally, a sheet-type device that is placed under a user to acquire the user's status is known. For example, a sheet-type sensor device that is placed on a bed apparatus to acquire the user's status is known. Here, various methods are known for fixing the sheet-type sensor device in a bed apparatus that can perform a back-raising operation or the like by moving the bottom.

[0012] For example, a method is known in which a sensor device is fixed by using a hook to hang it from one end of the back bottom or the back frame of the bed apparatus. However, this method requires that the sensor device be installed on the back bottom, and it is not possible to install the sensor device in a location other than the back bottom. Furthermore, when using multiple seat-type sensor devices, it is necessary to properly install the sensor devices in locations other than the back bottom of the bed apparatus, but it has not been possible to install them properly.

[0013] Furthermore, since the shapes and dimensions of bed devices vary, it has been difficult to properly attach the sensor device to each bed device.

[0014] In addition, the bed device can perform back-raising and back-lowering operations by rotating the back bottom, and can perform knee-raising (leg-raising) and knee-lowering (leg-lowering) operations by rotating the waist bottom and foot bottom.

[0015] In this case, if a sheet-type sensor device is placed on the bottom, the sensor device needs to follow the movement of the bottom, but if the sheet-type sensor device is not installed properly, accurate measurements may not be possible. Also, if the sensor device is not installed properly, such as if it is installed in a misaligned position, the movement of the mattress or futon (mattress, etc.) on top of the sensor device can cause discomfort to the user.

[0016] Furthermore, in the case of a multi-bed room in a hospital or facility, it is necessary to attach or detach a sensor device depending on the user's symptoms or when users are replaced. In this case, if it were possible to attach or detach the sensor device to or from a bed device in a simple manner, it would be advantageous in that it would improve usability, but in general, it is necessary to provide a sensor device for each bed device, which makes it difficult to use the sensor device appropriately or efficiently.

[0017] The technology of the present disclosure has been proposed to solve one or more of these problems, and below, an embodiment in which the mounting member etc. of the present disclosure is applied will be described.

[0018] The user is a person who lies on a bed device including a sensor device or who uses the bed device. The user is not limited to sick people or people requiring care, but also includes healthy people. The user also includes not only adults and elderly people, but also children.

[0019] The term "staff" also includes medical staff at the hospital where the user is hospitalized and staff at the facility where the user resides. In addition, in the case of a user's home, the term "staff" also includes family members who provide nursing care or care for the user.

[0020] [1. Overall structure] 1 is a diagram showing the entire bed system 1. An acquisition device 5 is provided on a bed device 3.

[0021] The bed apparatus 3 has, for example, a bottom 20 provided on a frame 31. The bottom 20 has, for example, a back bottom 21, a waist bottom (kuma-line bottom) 23, a knee bottom 25, and a foot bottom 27, from the head side (H side) to the foot side (F side) as seen from the user lying supine on the bed apparatus 3 in Fig. 1. Note that, as seen from the user (in a supine position) on the bed apparatus, the right side is the R side and the left side is the L side.

[0022] The bed apparatus 3 can perform, for example, a back-raising operation (back-lowering operation) or a leg-raising operation (leg-lowering operation) by operating the back bottom 21, the waist bottom 23, etc. The bed apparatus 3 has a general configuration. For example, as shown in FIG. 1, it may be provided with a headboard and a footboard, or holes for providing side rails. It may also have a driving device (actuator) that changes the shape of the bed apparatus 3 by operating each bottom as described above, or that changes the height of the bed apparatus 3 by moving the frame 31 up and down.

[0023] The acquisition device 5 is a sheet-like sensor capable of acquiring the state, movement, etc. of the user, and is positioned below the user. For example, the acquisition device 5 can be placed on the bed apparatus 3. The acquisition device 5 being placed (or placed) on the bed apparatus 3 means that the acquisition device 5 is positioned closer to the user than the bottom 20 of the bed apparatus 3. A specific method for placing the acquisition device 5 is, for example, to place the acquisition device 5 so that it is sandwiched between the bottom 20 of the bed apparatus 3 and a mattress or futon (hereinafter referred to as a mattress, etc.). The acquisition device 5 may also be placed on the mattress, etc. In other words, the acquisition device 5 is positioned so that it is below the user. Therefore, when the user is in a lying position on a futon laid on tatami or flooring (floor), the acquisition device 5 may be placed under the user. In this case, the acquisition device 5 may be placed on or under the futon (on the tatami or floor).

[0024] The acquisition device 5 can be connected to, for example, a status acquisition device 10 and an optional motion acquisition device 15 that can be connected to the status acquisition device 10. Here, the status acquisition device 10 is an example of a status acquisition device that can acquire the user's status based on load values ​​and vibrations acquired from multiple types of sensors, and serves as a main sensor device. The motion acquisition device 15 is, for example, a sensor device that acquires load values ​​from a pressure sensor, and serves as an optional sensor device. The motion acquisition device 15 may be provided as needed. That is, the status acquisition device 10 may be a sensor device that acquires the user's status, or the motion acquisition device 15 may simply be a sensor device that acquires load. The motion acquisition device 15 is a device that can detect the user's motion, and may be referred to as a motion detection device or simply as a detection device.

[0025] Here, the user status in this embodiment indicates a status related to the user, and includes, for example, the following statuses. - Status of the user in and out of bed Your sleep state (e.g., sleep, wakefulness, depth of sleep (REM sleep, non-REM sleep, etc.)) - The user's posture (e.g., standing, sitting, lying down, etc.) · The user's sleeping position (supine, lateral, prone, etc.) and sleeping position - Status based on the user's biological information (heart rate, breathing, SpO2, blood pressure, body temperature, etc.)

[0026] Here, a state other than that based on the user's biometric information may be referred to as a first state, and the state based on the biometric information may be distinguished from a second state. Status acquisition device 10 may be capable of acquiring the user's first state and the user's second state using different types of sensors.

[0027] In FIG. 1, the status acquisition device 10 is provided on the back bottom 21 as a first position. The status acquisition device 10 can detect the movement of the user on the status acquisition device 10 (for example, movement based on the user's movements, minute movements such as the user's heart rate and breathing, body movements, etc.). Based on the detected movement of the user, the status acquisition device 10 can acquire, for example, the user's state such as whether they are in bed or out of bed, their posture, their state such as their sleeping posture, and their biometric information such as their heart rate and breathing rate. Here, the first position is preferably near the head side of the bed apparatus 3, and more preferably, it is preferably a position near the back when the user is in a supine position.

[0028] The status acquisition device 10 can be connected to an optional motion acquisition device 15 via a cable 13. The configuration of the motion acquisition device 15 for acquiring the user's motion (movement) is basically the same as that of the status acquisition device 10, and some of the configuration may be omitted. For example, some of the functions provided by the status acquisition device 10 (e.g., a sensor capable of acquiring biometric information such as the user's heart rate and breathing, a wireless communication function, etc.) may be omitted. Furthermore, when the same device as the status acquisition device 10 is used, it may be used in place of the motion acquisition device 15 by switching between master and slave through settings, for example.

[0029] The motion acquisition device 15 is provided at the second position, for example, on the knee bottom 25. The second position is preferably provided closer to the foot side of the bed apparatus 3 than the first position. In this embodiment, the motion acquisition device 15 is provided on the knee bottom 25 so that the position of the motion acquisition device 15 can be easily fixed.

[0030] Here, it is preferable that the status acquisition device 10 provided on the back bottom 21 has some play when installed. By having some play in the position where the status acquisition device 10 is installed, the status acquisition device 10 will be in an appropriate position regardless of the positional deviation of the mattress placed on the back bottom 21, for example, even when the back bottom 21 is raised or lowered.

[0031] Moreover, it is preferable that the motion acquisition device 15 is fixed at a position above the knee bottom 25. For example, even if the knee bottom 25 rises or falls, it is preferable that the motion acquisition device 15 does not move from the position where it was initially installed.

[0032] In this way, the state acquisition device 10 is installed at a position corresponding to the back of the user when lying supine on the bed device 3 (mattress, etc.). The motion acquisition device 15 is installed at a position ranging from the vicinity of the waist to the vicinity of the thighs of the user when lying supine on the bed device 3 (mattress, etc.).

[0033] [2. Configuration of acquisition device] The following describes the configurations of the status acquisition device 10 and the action acquisition device 15. For example, the configuration will be described in which the status acquisition device 10 functions as a main body sensor and the action acquisition device 15 functions as an optional sensor.

[0034] (Entire acquisition device) 2A and 2B are diagrams showing the appearance of the acquisition device 5. Fig. 2A shows the appearance of the status acquisition device 10, and Fig. 2B shows the appearance of the action acquisition device 15. In this case, the status acquisition device 10 in Fig. 2A functions as a main body sensor device, and the action acquisition device 15 in Fig. 2B functions as an optional sensor device.

[0035] The status acquisition device 10 has a thin and simple structure. One end of the status acquisition device 10 may have a control device and a notification unit that indicates the status of the status acquisition device 10. For example, in FIG. 2, the status acquisition device 10 may have a display unit that indicates the power supply status and a display unit that indicates the communication status of the status acquisition device 10.

[0036] The status acquisition device 10 may also display necessary information on its side surface. For example, while a side view is shown in FIG. 2(a), a serial number may be written on the side view. The status acquisition device 10 may also have an LED on its side surface to indicate necessary information by the LED's lighting state. For example, the status acquisition device 10 may display the communication status with other devices using an LED. The status acquisition device 10 may also flash an LED in conjunction with the user's biometric information (e.g., breathing, heart rate). The status acquisition device 10 may also have a display unit on its side surface that is composed of a liquid crystal display or an organic EL display. The status acquisition device 10 may display information based on the user's biometric information on the display unit.

[0037] For example, in a hospital or facility, the status acquisition device 10 is used for a plurality of bed devices 3. In this case, as described above, if various information is displayed on the side of the status acquisition device 10, when a staff member or the like checks the correspondence between the bed device 3 (i.e., the user using the bed device 3) and the status acquisition device 10, the staff member or the like can identify the status acquisition device 10 simply by looking at the side of the status acquisition device 10.

[0038] 2(b), the design of the behavior acquisition device 15 may be different from that of the status acquisition device 10. For example, the status acquisition device 10 has a white front and a dark gray back. The behavior acquisition device 15 may be differentiated from the status acquisition device 10 by unifying the entire surface in dark gray, for example.

[0039] Furthermore, unlike the state acquisition device 10, the action acquisition device 15 has a simple design without patterns or tape around the edges. This means that even if the state acquisition device 10 is replaced with a new device, the action acquisition device 15 may still be used as is. In this case, the simple design of the action acquisition device 15 makes it possible to use it without any sense of incongruity.

[0040] [3. Installation method] Next, a method and members for attaching the acquisition device 5 to the bed device 3 will be described.

[0041] [3.1 Installation of status acquisition device] A method for attaching the status acquisition device 10 will be described with reference to Figure 3. The status acquisition device 10 has a handle 82. The attachment member 50 also has a hook 51 on one end side of the belt 53. The hook 51 is provided so that it can be hooked onto the end of the back bottom 21, for example, as shown in Figure 3(b).

[0042] Furthermore, the belt 53 has hook and loop fasteners 55 (hook and loop fasteners 55a and 55b) on one surface (for example, the upper surface as viewed in FIG. 3(a)). Here, the hook and loop fasteners 55a are provided on the opposite side of the belt 53 from the hooks 51.

[0043] For example, the user passes belt 53 through handle 82 on the side of status acquisition device 10. Then, the user folds back the side of belt 53 opposite hook 51 so that hook and loop fasteners 55a and 55b overlap. By attaching hook and loop fasteners 55a and 55b together, status acquisition device 10 is placed at a predetermined position on back bottom 21. It is also preferable to place status acquisition device 10 so that its center coincides with the center of back bottom 21. More preferably, status acquisition device 10 is placed so that the center of sensor unit 108 (shown in FIG. 8, which will be described later) coincides with the center of back bottom 21.

[0044] [3.2 Installation of motion acquisition device] The following description will be made with reference to a method for attaching motion acquisition device 15. Fig. 4 is a diagram showing attachment member 60. Fig. 5 is a schematic diagram for explaining a method for attaching motion acquisition device 15 using attachment member 60.

[0045] The attachment member 60 has two hooks 61 connected by an expandable stretchable portion 63. Here, the hooks 61 are, for example, resin hooks, and the stretchable portion 63 is, for example, plain woven rubber. The stretchable portion 63 also has a hook-and-loop fastener 65 on one side as an example of an attachment portion.

[0046] Here, the hook-and-loop fastener 65 may be any member for attaching the motion acquisition device 15 to the attachment member 60. In the present embodiment, a hook-and-loop fastener is described as an example of an attachment portion, but any member that can attach the motion acquisition device 15 to the attachment member 60 may be used, for example, a member that uses magnetic force (a magnet), a button, or the like. The attachment portion may also be a mounting member to which the motion acquisition device 15 can be attached. That is, the motion acquisition device 15 is mounted to a mounting portion (mounting member).

[0047] As shown in FIG. 5(a), the attachment member 60 is attached to the bottom of the bed apparatus 3 (e.g., the knee bottom 25). For example, the attachment member 60 is attached so that it is clamped to the knee bottom 25 by hooks 61 provided on both ends of the attachment member 60. For example, as shown in FIG. 4(a), the hooks 61 protrude downward as viewed in the drawing (toward the bottom of the bed apparatus 3). The lower side of the hook 61 is inclined toward the upper center and is narrower than the end of the attachment member 60. The hooks 61 are made of an elastic material such as synthetic resin (e.g., plastic) or rubber. Therefore, the attachment member 60 is attached to the knee bottom 25 so that the side walls of the knee bottom 25 fit into the openings of the hooks 61. In other words, the attachment member 60 is attached to the knee bottom 25 by clamping the hooks 61 on both ends so that they are caught on the side walls of the knee bottom 25.

[0048] That is, the user stretches the stretchable portion 63 of the attachment member 60 and hooks the hook 61 onto the end of the knee bottom (or the side wall at the end). Here, the hooks 61 on both ends are respectively hooked onto the knee bottom 25, and the attachment member 60 as a whole is fixed so as to be sandwiched between the knee bottom 25. In addition, the stress caused by the contraction of the stretchable portion 63 causes the attachment member 60 to be sandwiched between the knee bottom 25.

[0049] Furthermore, hook and loop fasteners 65, which are an example of an attachment portion, are arranged to be positioned on the opposite side from where the hooks 61 protrude. Therefore, the hook and loop fasteners 65 are positioned facing the upper side of the bed apparatus 3.

[0050] 5(b) is a diagram illustrating the state in which the motion acquisition device 15 is attached to the attachment member 60. A hook-and-loop fastener 84 is provided on the back surface of the motion acquisition device 15 as an auxiliary member for attaching it to the attachment part. By adhering the hook-and-loop fastener 65 of the attachment member 60 of the motion acquisition device 15 to the hook-and-loop fastener 84, the motion acquisition device 15 is detachably attached to the knee bottom 25 via the attachment member 60.

[0051] Here, the hook-and-loop fastener 84 of the motion acquisition device 15 may be provided, for example, on one surface (for example, the lower surface side, the bed apparatus side, as viewed in the drawing) of the motion acquisition device 15. Alternatively, the hook-and-loop fastener 84 may be provided on a cover of the motion acquisition device 15.

[0052] Note that a method other than hook-and-loop fasteners may be used as the attachment portion for attaching the motion acquisition device 15. For example, the attachment portion may be a method that utilizes magnetic force (e.g., a magnet, etc.). For example, a magnet may be provided on the attachment member 60, and a metal part or magnet may be provided as an auxiliary member on the motion acquisition device 15. Then, the motion acquisition device 15 and the attachment member 60 may be attached by magnetic force.

[0053] The motion acquisition device 15 may be attached in other ways. For example, a handle 86 may be provided on the motion acquisition device 15. In this case, when attaching the attachment member 60 to the knee bottom 25, the attachment member 60 may be attached so as to pass through the handle 86. In this case, the attachment member 60 can be installed so as to sandwich the motion acquisition device 15.

[0054] Furthermore, although an example has been described in which the attachment member 60 is attached to the knee bottom 25, the attachment member 60 may also be attached to other bottoms. For example, the attachment member 60 may be attached so as to sandwich the components that make up the bottom of the back bottom 21, utilizing the gap in the back bottom 21. The attachment member 60 may also be attached to the waist bottom 23 or the leg bottom 27 in a similar manner.

[0055] [3.3 Connection between status acquisition device and operation acquisition device] As shown in FIG. 1, the state acquisition device 10 and the action acquisition device 15 are connected by a connection member 70 so as to be able to communicate with each other.

[0056] FIG. 6(a) is a diagram schematically illustrating the connecting member 70. The connecting member is preferably made of a stretchable material (e.g., highly stretchable fabric) so that it will not shift even if the positions of the state acquisition device 10 and the motion acquisition device 15 change. Furthermore, if another stretchable material (e.g., rubber) is placed inside the cover 71, the cover 71 does not need to be made of a highly stretchable fabric. In other words, it is sufficient that the entire connecting member 70 is stretchable. Because the connecting member 70 is stretchable, it is possible to absorb changes in the distance between the state acquisition device 10 and the motion acquisition device 15.

[0057] The device also has an expandable cover 71 and attachment parts 73 at both ends of the cover 71. For example, the attachment parts 73 are configured with a belt 73a and a snap button 73b. The belt 73a is passed through the handle 82 of the state acquisition device 10 or the handle 86 of the motion acquisition device 15, and the snap button 73b is fastened.

[0058] The connection member 70 also has a cable 75 used for communication between the state acquisition device 10 and the action acquisition device 15. The cable 75 is detachably attached to communication interfaces (not shown) of the state acquisition device 10 and the action acquisition device 15.

[0059] Furthermore, it is preferable that the excess portion of the cable 75 be stored inside the cover 71. The cable 75 is a piece of cloth sewn into a tubular shape, and the excess portion of the cable 75 can be stored inside the cover 71. This allows the cable 75 to be stored with slack inside the cover 71. The connecting member 70 may also include rubber (e.g., plain woven rubber) inside the cover 71. By providing an elastic body such as rubber inside the cover 71, the excess length of the cover 71 can be shortened by the stress of the rubber. The cable 75 may also be fixed with a cable tie to reinforcing members (e.g., tarpaulin) sewn inside both ends of the cover 71. This allows the cover 71 to expand and contract without changing the exposed length of the cable 75. Furthermore, since the excess portion of the cable 75 is not exposed from the cover 71, it is possible to prevent the cable 75 from being pinched between bottoms, etc.

[0060] By configuring the connecting member 70 in this manner, for example, an excess portion of the cable 75 is housed within the cover 71. This prevents the cable 75 from being pinched between the bottom, frame, etc. that constitute the bed apparatus 3.

[0061] 6(b) and (c) show the states in which the cover 71 of the connecting member 70 is expanded or contracted. For example, FIG. 6(b) shows the state in which the cover 71 is contracted, and FIG. 6(c) shows the state in which the cover 71 is expanded. By expanding and contracting the cover 71, even if the distance between the state acquisition device 10 and the motion acquisition device 15 changes during the back-raising operation of the bed apparatus 3, the connecting member 70 can absorb the change.

[0062] The connecting member 70 also has attachment portions 73 at both ends. The attachment portions 73 can be easily attached to and detached from the status acquisition device 10 and the motion acquisition device 15 by using snap buttons 73b. A label indicating the type of cable may be attached near the attachment portion 73. By referring to the label, the user can easily attach and detach the correct cable according to the type of connector.

[0063] [4. Details of acquisition device] The following describes in detail the configurations of the status acquisition device 10 and the action acquisition device 15. For example, the configuration will be described in which the status acquisition device 10 functions as a main body sensor and the action acquisition device 15 functions as an optional sensor.

[0064] 7 is a diagram schematically illustrating the acquisition device 5. For example, the status acquisition device 10 has a control unit 102 and a sensor unit 108. The sensor unit 108 is separated into two housings (members), for example, a sensor unit 108A and a sensor unit 108B, and the two sensor units are connected by a bendable member. Because the sensor unit 108 is separated into two, the status acquisition device 10 as a whole can be bent around the center.

[0065] Furthermore, for example, by using a bendable flexible member for the sensor unit 108, even if the sensor unit 108 is made of a single member, the entire acquisition device 5 can be configured to be bendable.

[0066] The sensor unit 108 has a first sensor 40 and a second sensor 42. Here, the first sensor 40 is, for example, a pressure-sensitive sensor. The first sensor 40 can detect a load applied to the first sensor 40. The first sensor 40 can acquire a first state of the user.

[0067] For example, the status acquisition device 10 can acquire the following content as the first status of the user based on the load (load value) detected by the first sensor 40:

[0068] Whether the user is in bed or out of bed on the bed system 1 (out-of-bed status) The user's sleeping position and posture (for example, whether the user is in a sitting position, edge sitting position, supine position, prone position, lateral position, etc. on the bed system 1) The position of the user on the bed system 1 (e.g., the position of the center of gravity of the user, the sleeping position of the user) Other movements of the user (for example, the user turns over, moves to the end of the bed system 1, or the user sleeps with the head and feet reversed, etc.) Furthermore, the state acquisition device 10 can acquire a change in the state of the user from a change in the load detected by the first sensor 40.

[0069] The second sensor 42 is a highly sensitive sensor capable of detecting minute body movements of the user. Here, the second sensor 42 is a sensor capable of acquiring vibrations with higher sensitivity than the first sensor 40. For example, the second sensor 42 can detect minute movements such as the user's heartbeat and body movements due to breathing. The second sensor 42 can acquire biometric information as a second state of the user.

[0070] As an example of the second sensor 42, for example, an air pad may be provided in the sensor unit 108 via an air tube from the sensor processing device 106 provided in the control unit 102. The air pad may be disposed at the position of the second sensor 42 described in Fig. 3. Also, a highly sensitive (high resolution) vibration sensor (such as a high resolution three-axis acceleration sensor, a sensor further combining a gyro sensor, or a high resolution piezoelectric sensor) may be disposed at the position of the second sensor 42 described in Fig. 3 and connected to the control device 104.

[0071] Furthermore, the sensor processing device 106 may change the types of values ​​acquired from the first sensor 40 and the second sensor 42. For example, the first sensor 40 may measure and output the absolute amount of load at a predetermined timing. Furthermore, the second sensor 42 may measure and output the amount of change in load at a predetermined timing. For example, when the first sensor 40 detects a user, it outputs a value based on the load acting on the first sensor 40. For example, when the first sensor 40 detects a load of 10 kg, it continues to output a sensor value corresponding to 10 kg. In contrast, after the second sensor 42 detects a load of 10 kg and the load stabilizes, it stops outputting sensor values.

[0072] As a result, for example, the status acquisition device 10 can determine the center of gravity of the user and the user's position based on the absolute amount of load output by the first sensor 40. This is because the load fluctuates greatly due to the user's movement, and therefore the sensor value fluctuates greatly based on the load movement. Therefore, it is preferable that the status acquisition device 10 uses the sensor value of the first sensor 40.

[0073] In contrast, for example, the status acquisition device 10 can determine the user's vital signs (heart rate, breathing) based on the amount of change in the load output by the second sensor 42. This is because the movements (body movements) based on the user's vital signs fluctuate little. Therefore, since the second sensor 42 is a highly sensitive sensor compared to the first sensor 40 and the change in the sensor value of the load based on body movements is small, it is preferable that the status acquisition device 10 use the sensor value of the second sensor 42.

[0074] In this way, by using the second sensor 42, which can detect vibrations with higher sensitivity than the first sensor 40, the status acquisition device 10 can further acquire the user's biometric information from the user's minute body movements, such as body movements due to the user's breathing and body movements due to the heartbeat.

[0075] Here, it is preferable that the first sensors 40 are provided at equal intervals. In the status acquisition device 10 of this embodiment, four first sensors 40A, 40B, 40C, and 40D are provided at equal intervals as the first sensors 40. In addition, in the status acquisition device 10 of this embodiment, two second sensors 42A and 42B are provided at equal intervals as the second sensors 42. Here, the number of first sensors 40 and second sensors 42 is one example, and more than two sensors may be provided.

[0076] The first sensors 40 are preferably arranged at equal intervals in a straight line along the longitudinal direction of the status acquisition device 10. When the status acquisition device 10 is installed on the bed apparatus 3, the first sensors 40 are arranged at equal intervals in a straight line along the lateral direction of the bed apparatus 3. That is, the first sensors 40 and the second sensors 42 are arranged along the left-right direction of the user.

[0077] The number of first sensors 40 (40A to 40D) provided in the status acquisition device 10 may be the same as the number of third sensors 45 (45A to 45D) provided in the motion acquisition device 15, which will be described later. The first sensors 40 provided in the status acquisition device 10 and the third sensors 45 provided in the motion acquisition device 15 may be arranged on a straight line along the longitudinal direction of the bed apparatus 3. In other words, the first sensors 40 and the third sensors 45 are arranged along the up-down direction of the user.

[0078] The arrangement of the status acquisition device 10 and the action acquisition device 15 does not have to be such that the first sensor 40 is strictly aligned in a straight line. For example, if the attachment positions of the status acquisition device 10 and the action acquisition device 15 result in the first sensor 40 and the third sensor 45 being offset from a straight line by a few centimeters, this is considered to be an error, and there is no problem in considering them to be aligned in a straight line.

[0079] The control device 104 receives signals from the first sensor 40 and the second sensor 42. Then, based on the acquired signals (for example, load value, vibration level, etc.), the control device 104 can acquire the user's state (first state) and the user's biological information (for example, heart rate, breathing, etc.) (second state).

[0080] The status acquisition device 10 may also be connected to an optional motion acquisition device 15 via a cable 13. The motion acquisition device 15, like the status acquisition device 10, has a control unit 152 and a sensor unit 158.

[0081] The status acquisition device 10 and the action acquisition device 15 may be connected wirelessly. The wireless connection method may be any of communication methods such as wireless LAN, Bluetooth (registered trademark) which is a short-range wireless communication, and wireless USB.

[0082] In the motion acquisition device 15, similarly to the state acquisition device 10, the sensor unit 158 ​​may be configured with two units, sensor unit 158A and sensor unit 158B. Furthermore, the sensor unit 158 ​​has third sensors 45A, 45B, 45C, and 45D as the third sensor 45. The third sensor 45 is a sensor capable of detecting a load, and is the same as or has the same performance as the first sensor 40. The control device 154 of the motion acquisition device 15 calculates a load value based on a signal acquired from the third sensor 45, and transmits the calculated load value to the control device 104 of the state acquisition device 10.

[0083] As a result, when the action acquisition device 15 is connected, the status acquisition device 10 can acquire load values ​​from eight load sensors, including the first sensor 40 and the third sensor 45 provided in the action acquisition device 15.

[0084] Furthermore, since the action acquisition device 15 is an optional acquisition device, it may be configured with only what is necessary compared to the state acquisition device 10. For example, the action acquisition device 15 does not need to be provided with a highly sensitive sensor capable of acquiring biometric information of the user, which corresponds to the second sensor 42. Furthermore, the control device 154 of the action acquisition device 15 may only have the necessary configuration to transmit the load value acquired from the third sensor 45 to the state acquisition device 10.

[0085] (sensor unit) 8 and 9 are diagrams illustrating the configuration of the sensor unit 108. FIG. 8 is a diagram illustrating the sensor unit 108 of the acquisition device 5, for example, the status acquisition device 10. FIG. 9 is a diagram illustrating the sensor unit 108B of the sensor unit 108. As shown in FIG. 8, the diagram illustrates the arrangement of the first sensor 40 (first sensors 40C and 40D arranged in the sensor unit 108B in FIG. 7) and the second sensor 42 (second sensor 42B arranged in the sensor unit 108B in FIG. 7) in a housing 110 of the sensor unit 108B. The housing 110 is the lower housing of the sensor unit 108.

[0086] The following describes the features of the sensor unit 108. The sensor unit 108 has the second sensor 42 disposed approximately in the center of the sensor unit 108. For example, the sensor unit 108A has the second sensor 42A disposed approximately in the center. The sensor unit 108B has the second sensor 42B disposed approximately in the center.

[0087] Furthermore, the first sensor 40 is arranged in the sensor unit 108 on a straight line along the longitudinal direction of the status acquisition device 10 so as to sandwich the second sensor 42. In this way, it is preferable that the first sensor 40 and the second sensor 42 are arranged on a straight line in the longitudinal direction of the status acquisition device 10. Furthermore, the first sensor 40 and the second sensor 42 do not necessarily have to be arranged on a straight line. For example, the second sensor 42 may be arranged in a position shifted upward as shown in FIG. 7.

[0088] Here, the sensor unit 108 may have a buffer member provided between the upper and lower housings. For example, as shown in Fig. 8(a), the housing 110 has buffer sections 112 provided at multiple locations. The buffer sections 112 are configured to include a buffer member such as resin, rubber, urethane, or sponge, and may be provided at a position where the lower housing 110 and the upper housing (not shown) come into contact with each other.

[0089] 8(b) is an enlarged view of the vicinity of the buffer section 112. For example, the buffer section 112 may be injection molded with the housing 110, integrally molding the buffer section 112 and the housing 110. By molding the buffer section 112 integrally with the housing 110, it is possible to omit the manufacturing step of bonding a buffer section to the housing 110 separately.

[0090] The buffer material used in the buffer section 112 may be, for example, a non-slip material such as polyurethane rubber. The buffer material may be, for example, a buffer material such as rubber or polyurethane, a vibration-isolating material, or a non-slip material.

[0091] The housing 110 may have a guide portion that bundles and guides the cables connected to the first sensor 40 and the second sensor 42. For example, as shown in Fig. 8(a), the housing 110 has a guide portion 116 that guides the cable connected to the first sensor 40. The housing 110 also has a guide portion 114 that guides the cable (air tube) connected to the second sensor 42.

[0092] The guide portion 114 may be configured with claw members for gripping the cable from both sides to fix the movement of the cable. By providing one or more guide portions 114 at a position where the cable connected to the second sensor 42 passes, the cable (e.g., an air tube) can be arranged along the guide portion 114. For example, FIG. 8(c) is an enlarged view of the guide portion 114.

[0093] Furthermore, by providing the guide portion 116 at a position where a cable connected to the first sensor 40 passes through, it is possible to bundle the cable (for example, an air tube) using the guide portion 116. For example, FIG. 5(d) is an enlarged view of the guide portion 116.

[0094] Guide portion 116 has a wide shape so that two cables connected to first sensor 40 can be gathered together. Also, a partition is provided in the center of guide portion 116 and is covered with claw members, so that two cables can be held individually. Also, by making the upper sides of the claws of guide portion 116 flat, the height of guide portion 116 can be reduced.

[0095] 8(e) shows the arrangement of the first sensor 40 and the second sensor 42. FIG. 8(e) is an enlarged perspective view of the first sensors 40C, 40D and the second sensor 42B.

[0096] Here, the housing 110 may have a rib 46 formed in a position corresponding to the first sensor 40. Furthermore, the housing 110 may have a rib 48 formed in a position corresponding to the second sensor 42. By providing the ribs 46 and 48 on the housing 110, it becomes possible to easily and accurately position the first sensor 40 and the second sensor 42, for example, during design or manufacturing. Furthermore, by providing the ribs 46 and 48 on the housing 110, it becomes possible to ensure strength.

[0097] 8(f) is a schematic cross-sectional view of the first sensor 40 and the second sensor 42. As shown in FIG. 8(f), the first sensor 40C and the first sensor 40D are provided in the lower housing 110. Here, in consideration of the influence on the second sensor 42 placed between the first sensors 40, a pusher 47 may be provided on the first sensor 40. The pusher 47 is made of, for example, polyurethane rubber.

[0098] In the status acquisition device 10, the upper housing 111 comes into contact with the first sensor 40 and the second sensor 42B, allowing each sensor to detect a load and acquire the user's body movements. Here, if the first sensor 40 is a pressure-sensitive sensor, a pusher 47 is provided between the housings 111 so that a load is applied to the pressure-sensitive portion. In other words, when a load is applied from the upper housing 111, the pusher 47 presses the first sensor 40 (pressure-sensitive sensor), and the first sensor 40 can detect the load.

[0099] Here, if the height of the pusher 47 is higher than that of the second sensor 42 when it is provided on the first sensor 40, the second sensor 42 will not be able to correctly detect the user's body movements, and the status acquisition device 10 will not be able to correctly acquire biometric information. Furthermore, if a mattress is placed on the status acquisition device 10, the weight of the mattress may cause the first sensor 40 to make a false detection. Therefore, it is preferable that the height of the pusher 47 is lower than that of the second sensor 42 when it is provided on the first sensor 40. Furthermore, it is preferable that the height of the pusher 47 is higher than that of the buffer section 112 when it is provided on the first sensor 40. This is because if the height of the pusher 47 when provided is lower than that of the buffer section 112, a load will be applied to the buffer section 112, and the first sensor 40 will not be able to correctly acquire the load.

[0100] In this way, by appropriately adjusting the height of the pusher 47 relative to the second sensor 42, it is possible to prevent erroneous detection by the first sensor 40 without affecting the acquisition of the user's biometric information. For example, if the height of the pusher 47 is too low, it will not be possible to detect the load, and information about the user will not be acquired even if the user stands on the status acquisition device 10. Furthermore, if the height of the pusher 47 is too high, it will react to a mattress, futon, blanket, etc., resulting in erroneous detection. By adjusting the height in this way, the pusher 47 will not move when an object used on the bed device 3, such as a comforter or blanket, stands on the status acquisition device 10, but will move when a user of an expected weight stands on the status acquisition device 10.

[0101] Sensor unit 158 ​​has almost the same configuration as sensor unit 108. Since sensor unit 158 ​​does not have second sensor 42, for example, a buffer material may be provided in the location where second sensor 42 is located. This allows sensor unit 108 and sensor unit 158 ​​to use the same housing.

[0102] Additionally, the housing 110 may have a cable guide installed midway to prevent the cable from moving. It is also preferable that the housing 110 has a portion where the cable is connected to prevent the cable from being twisted and damaging connectors inside the product. For example, it is preferable to provide a rib on the housing 110 to limit the movement of the cable. The cable may also be arranged inside the housing 110 so that its movement is limited by using a cable tie around the cable.

[0103] [5. Functional Configuration] FIG. 10 is a diagram illustrating the functional configuration of the state acquisition device 10, the action acquisition device 15, and the attachment member 60 in the embodiment.

[0104] The state acquisition device 10 and the operation acquisition device 15 have a control unit 1000 and a control unit 1500 for controlling the respective devices. The control unit 1000 (control unit 1500) reads and executes information and programs stored in the storage unit 1010 (storage unit 1510) to perform various processes.

[0105] The storage unit 1010 (storage unit 1510) stores various information, data, and programs. The storage unit 1010 is, for example, a semiconductor memory such as a ROM or RAM, but may also be a recording medium such as a USB memory or an SD card (registered trademark). Data may also be stored on the cloud via the communication unit 1030, and various operating functions may be realized by executing a cloud-based program.

[0106] The acquisition unit 1020 (acquisition unit 1520) acquires sensor information via the acquisition device described above. The sensor information may be the user's load value or biometric information values ​​such as heart rate and respiratory rate. The acquired biometric information values ​​may be stored in, for example, the storage unit 1010 (storage unit 1510). The acquisition unit 1020 may be, for example, the first sensor 40 (first sensors 40A, 40B, 40C, 40D) or the second sensor 42 in FIG. 7. The acquisition unit 1520 may also be the first sensor 40 (first sensors 40E, 40F, 40G, 40H).

[0107] The communication unit 1030 (communication unit 1530) communicates with other devices. The communication unit 1030 may be, for example, an interface such as a USB, or an interface connectable to a network such as a wireless LAN. The communication unit 1030 may also be a communication interface such as Bluetooth (registered trademark). By connecting the communication unit 1030 and the communication unit 1050, for example, a sensor value acquired by the action acquisition device 15 can be acquired by the status acquisition device 10.

[0108] The attachment member 60 may also include a communication module, which includes a control unit 6000, a storage unit 6010, a position information acquisition unit 6020, and a communication unit 6030.

[0109] Here, the control unit 6000 reads and executes a program from the storage unit 6010, connects to other devices via the communication unit 6030, and transmits location information acquired by the location information acquisition unit 6020. For example, the control unit 6000 can transmit identification information of the mounting member 60 stored in the storage unit 6010.

[0110] Furthermore, the communication module of the mounting member 60 may acquire the location information when it is possible to acquire the location information using the location information acquisition unit 6020. The location information may be, for example, general location information such as latitude and longitude information, information about the acquisition device 5 fixed to the mounting member 60, or information about the bed apparatus 3 to which the mounting member 60 is attached. Furthermore, the mounting member 60 may also transmit information about the user.

[0111] 10, a terminal device 90 can also be connected. The terminal device 90 is, for example, a computer, a tablet, or a smartphone. The control unit 9000 of the terminal device 90 reads and executes a program from a storage unit 9010, and the control unit 9000 can perform various processes.

[0112] Like a general terminal device, the terminal device 90 has a display operation unit 9020. The display operation unit 9020 has, for example, a display device that displays various information and an operation device that accepts input from a user. The display operation unit 9020 is, for example, a device that uses a touch panel or the like.

[0113] The attachment member 60 may transmit the location information, for example, when it receives a request to obtain location information from the acquisition device 5, or may transmit the location information periodically. The terminal device 90 may obtain the location of the attachment member 60 via the communication unit 9530. Alternatively, the status acquisition device 10 may obtain the location of the attachment member 60.

[0114] 11(a) shows an example of a table in which information transmitted by the attachment member 60 is acquired and managed by the terminal device 90. For example, the terminal device 90 may store an acquisition device ID and / or a user ID in association with an attachment member ID.

[0115] The terminal device 90 can determine the position where the attachment member 60 is located by using the identification information of the acquisition device and the identification information of the user.

[0116] 11(b) is a table for managing the position of the attachment member 60. For example, information on the bed apparatus 3 to which the attachment member 60 is attached is also stored. This makes it possible to clarify where the attachment member 60 is located by using the terminal device 90.

[0117] Fig. 12 is an example of a display screen displayed on the terminal device 90. Fig. 12(a) displays the location where the mounting member 60 is being used. For example, the mounting member 60 acquires information about the bed apparatus 3 to which the mounting member 60 is attached using the position information acquisition unit 6020. Then, the terminal device 90 displays the ID of the mounting member and the location of the bed apparatus 3 to which the mounting member 60 is attached. In addition, the mounting member 60 determines whether the acquisition device 5 is attached.

[0118] The terminal device 90 may then display whether the acquisition device 5 is fixed to each attachment member 60. The attachment member 60 may also transmit information that the attachment member 60 is attached to the acquisition device 5. The acquisition device 5 may transmit the ID of the attachment member and information about the acquisition device 5 together to the terminal device 90.

[0119] 12(b) is a display screen for searching for an attachment member 60 from the terminal device 90. For example, the display screen of the terminal device 90 in FIG. 12(b) displays a list of attachment members 60 to which the acquisition device 5 is not fixed. Here, the attachment member 60 to be called is selected from the terminal device 90 and processing is executed. Then, the attachment member 60 can notify the user by a notification unit (for example, a buzzer or an LED) included in the attachment member 60. Furthermore, the terminal device 90 may display the position of the attachment member 60 (for example, a direction, a distance, a point on a map, etc.).

[0120] By using the notification from the attachment member 60, staff or the like can easily confirm which bed apparatus 3 the attachment member 60 is on.

[0121] [6. Other configurations] The status acquisition device 10 can use short-distance wireless communication to perform various settings and check information.

[0122] For example, the terminal device 90 is connected to the status acquisition device 10 via short-range wireless communication using Bluetooth (registered trademark). The terminal device 90 may then set network information for the status acquisition device 10 through communication via Bluetooth. This makes it possible to set the IP address of the status acquisition device 10 in the terminal device 90, and then connect using an information processing device (e.g., a computer).

[0123] Furthermore, the terminal device 90 can periodically acquire the user's status (biometric information, sleeping position, etc.) by connecting to the status acquisition device 10. Furthermore, if the terminal device 90 is a computer installed in a nurse station or staff station, for example, it may acquire information from the status acquisition device 10 in real time.

[0124] [7. Other] As described above, based on the above-described embodiment, the following unique effects not found in the prior art can be expected.

[0125] Even when the bed apparatus 3 performs movements such as lifting the back or knees, the acquisition device 5 does not shift and can acquire the state of the user at a fixed position. In addition, the flexibility of the stretchable portion (e.g., rubber) makes it possible to provide an attachment member that can attach the acquisition device 5 to a variety of bed apparatuses 3. Furthermore, by using an easily detachable fixing member such as a hook-and-loop fastener for the attachment member, the acquisition device 5 can be placed in an appropriate position regardless of the dimensions of the bed.

[0126] Furthermore, the connection member 70 is configured to be fixed to the acquisition device 5 using members that can be easily attached and detached at both ends, such as snap buttons. Therefore, even a person who has no knowledge of bed structures or wiring can easily perform wiring between the acquisition devices 5.

[0127] Furthermore, the connecting member 70 protects the cable 75 using the cover 71, thereby making it possible to prevent the cable 75 from being caught in a moving part of the bed apparatus 3 or in a narrow space.

[0128] [8. Variations] The present disclosure is not limited to the above-described embodiments, and various modifications are possible. In other words, embodiments obtained by combining technical means that are appropriately modified within the scope of the gist of the present disclosure are also included in the technical scope of the present disclosure.

[0129] Although the above-mentioned embodiments are described separately for convenience of explanation, they can be combined to the extent possible. Furthermore, the present invention intends to obtain rights to any of the technologies described in the specification through amendments or divisional applications, etc.

[0130] In the above-described embodiment, the state acquisition device 10 is described as the first acquisition device and the motion acquisition device 15 is described as the second acquisition device among the acquisition devices 5. Here, the first acquisition device acquires the user's state (the first state includes the user's center of gravity of load, sleeping position, sleeping posture, large movements such as the user turning over in sleep, etc., and the second state includes the user's vital signs such as heart rate and breathing) based on two sensor values ​​(a load sensor and a load displacement sensor). The first acquisition device may acquire the user's state based on the load of the user acquired by the second acquisition device as needed. In addition to the above-described motion acquisition device 15, the second acquisition device may be, for example, a smartphone capable of detecting load or a load sensor provided in a bed apparatus.

[0131] The first acquisition device may be realized by combining a plurality of devices. For example, a device capable of detecting a load (such as a load sensor provided in a bed device) may be combined with a wearable terminal device, a smart watch, or the like worn by a user that can acquire the user's vital signs (biological information).

[0132] The scope of the present disclosure is not limited to the configurations explicitly described in the specification, but also includes combinations of the technologies disclosed in the specification. The configurations of the present disclosure for which a patent is sought are set forth in the appended claims, but it is not intended to exclude them from the technical scope on the grounds that they are not set forth in the claims.

[0133] Furthermore, in the above-mentioned specification, the statements "in the case of" and "when" are given as examples and are not intended to limit the configuration to the described contents. The disclosure also includes configurations that are not in these cases or situations, even if they would be obvious to a person skilled in the art, and the applicant intends to obtain rights to them.

[0134] Furthermore, the processes and data flows described in the specification are not limited to the order in which they are described. For example, the patent also discloses configurations in which some processes are deleted or the order is changed, and the patent holder intends to obtain the rights to such configurations.
