Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In this specification and each drawing, elements similar to those described above with reference to the previous drawings are given the same reference numerals and detailed descriptions thereof will be omitted as appropriate.

Figure 1(a) is a perspective view illustrating an electric bed and a control device. Figure 1(b) is a front view illustrating the control device.

As shown in FIG. 1(a), the control device 110 according to the embodiment includes an operation unit 10 (e.g., a "nurse control panel"). The operation unit 10 can be used to control the electric bed 310. The operation unit 10 is used by a caregiver (including a nurse, a doctor, etc.) of the user of the electric bed 310. The operation unit 10 may have various functions such as a function for turning lights on and off, a function for calling a caregiver or caregiver, or a function for turning the power on and off. The control device 110 may further include a hand switch 60 (remote controller). The hand switch 60 is mainly operated by the user of the electric bed 310 (the person sleeping in the electric bed).

The electric bed 310 is used, for example, in a hospital or a nursing home. The electric bed 310 may also be used at home.

As shown in FIG. 1A, the electric bed 310 has a bottom 70. The bottom 70 includes, for example, a back section 70a, an upper leg section 70b, and a lower leg section 70c. The angles of the back section 70a, the knee section 70b, and the leg section 70c relative to each other can be changed.

2, the bottom 70 includes a back bottom drive unit 71a, a knee bottom drive unit 71b, and a height drive unit 72. For example, each of the back bottom drive unit 71a, the knee bottom drive unit 71b, and the height drive unit 72 includes an actuator. Driving the back bottom drive unit 71a causes the back bottom 70a to operate, and the angle of the back of the user P (a person sleeping in the electric bed) can be changed. Driving the knee bottom drive unit 71b causes the knee bottom 70b and the leg bottom 70c to operate, and the angle between these bottoms can be changed. This allows the angle of the knees of the user P to be changed. The angles between each bottom may change in conjunction with each other. Driving the height drive unit 72 allows the height of the bottom 70 (the distance between the floor surface and the bed surface) to be changed.

The control device 110 includes a drive control unit 120. The drive control unit 120 includes a bottom control unit 121 and a height control unit 122. The back bottom drive unit 71a and the knee bottom drive unit 71b are electrically connected to the bottom control unit 121. The operation of the back bottom drive unit 71a and the knee bottom drive unit 71b is controlled based on a signal transmitted from the bottom control unit 121. The height drive unit 72 is electrically connected to the height control unit 122. The operation of the height drive unit 72 is controlled based on a signal transmitted from the height control unit 122.

As shown in FIG. 1(a), a cable 15 is connected to the operation unit 10. The cable 15 is used to electrically connect the operation unit 10 to the drive control unit 120. When the operation unit 10 is operated, a signal is sent to the drive control unit 120 through the wiring in the cable 15. The bottom control unit 121 and height control unit 122 of the drive control unit 120 drive each drive unit of the bottom 70 based on this signal.

1B, the operation unit 10 includes an operation surface 10a. The operation surface 10a includes an operation receiving unit 20.
For example, the operation reception unit 20 includes a panel 21 and a plurality of buttons 22a and 22b. The panel 21 has an input function and a display function. A user of the control device 110 touches the panel 21 to perform a first operation corresponding to the operation of the bottom 70. For example, as shown in Fig. 1(b), a plurality of icons IC1 to IC4 corresponding to the operation of the electric bed 310 are displayed on the panel 21. For example, the first operation is a touch of one of the plurality of icons IC1 to IC4.

For example, when icon IC1 related to "head" displayed on panel 21 is selected and up button 22a is pressed, angle θ1 (shown in FIG. 1(a)) of back bottom 70a relative to the horizontal plane increases. For example, when icon IC1 is selected and down button 22b is pressed, angle θ1 of back bottom 70a relative to the horizontal plane decreases. For example, when icon IC2 related to "feet" is selected and up button 22a is pressed, angle θ2 of knee bottom 70b relative to the horizontal plane increases. For example, when icon IC2 is selected and down button 22b is pressed, angle θ2 of knee bottom 70b relative to the horizontal plane decreases.

For example, when icon IC3 relating to "height" is selected and the up button 22a is pressed, the bottom 70 becomes higher. For example, when icon IC3 is selected and the down button 22b is pressed, the bottom 70 becomes lower. For example, when icon IC4 relating to "linkage" is selected and the up button 22a or the down button 22b is pressed, the angles θ1 and θ2 change simultaneously. These changes are caused by the movement of the bottom 70.

The operation reception unit 20 further includes a first button 23. A user of the control device 110 can move the bottom 70 from the first state to the second state by pressing the first button 23. For example, in the second state, the bottom 70 is horizontal. When the first button 23 is pressed, for example, the angle of the bottom 70 changes from the state shown in FIG. 3(a) (one example of the first state) to the state shown in FIG. 3(b) and becomes horizontal. Alternatively, as shown in FIG. 3(c), in the second state, the back bottom 70a may be horizontal and the leg bottom 70c may be located above the back bottom 70a. For example, when the bottom 70 moves from the first state to the second state, the height of the bottom 70 does not change.

For example, the above actions are performed while the button is being pressed. This results in safe operation.

The panel 21 can display, for example, information about the bottom 70 of the electric bed 310 (such as the angle and height of the bottom 70). The panel 21 may display a screen other than the screen for operating the electric bed 310. For example, information about a sensor attached to a person lying in the electric bed 310 or biometric information acquired by the sensor may be displayed on the panel 21. For example, the user of the control device 110 can switch the screen displayed on the panel 21.

For example, in an emergency, the bottom 70 is moved from the first state to the second state. For example, when cardiopulmonary resuscitation is performed on the user of the electric bed 310, the bottom 70 of the electric bed 310 is moved to the state shown in FIG. 3(b). For example, when the user of the electric bed 310 has a shock symptom, the bottom 70 of the electric bed 310 is moved to the state shown in FIG. 3(c).

It is desirable that the operation for moving the bottom 70 to the second state be simpler. This is because the operation of the bottom 70 can be started in a shorter time, and treatment can be started sooner. The control device 110 according to this embodiment includes a first button 23 for moving the bottom 70 to the second state. This eliminates the need for the person performing treatment to start or switch the screen of the panel 21, and also eliminates the need to search for an icon on the screen. Even if the panel 21 breaks down and the icon is not displayed, the bottom 70 can be moved to the second state by pressing the first button 23. The control device 110 according to this embodiment allows the operation for moving the bottom 70 to the second state to be performed more easily.

If the first operation is not performed during the first period, the panel 21 may turn off the display function. This can reduce the power consumption of the control device 110. Even while the display function of the panel 21 is off, the user of the control device 110 can press the first button 23 to move the bottom 70 to the second state.

When the bottom 70 moves to the second state by operating the first button 23, the angles θ1 and θ2 each change at a first speed. When the bottom 70 moves by operating the buttons 22a or 22b, the angles θ1 and θ2 each change at a second speed. The first speed is, for example, faster than the second speed. This allows the bottom 70 to move to the second state in a shorter time.

As shown in FIG. 4(a), for example, the operation unit 10 includes a first wiring 31, a second wiring 32, and a first processing unit 41 (e.g., a microcomputer). The first wiring 31 electrically connects the panel 21 and the first processing unit 41. The second wiring 32 electrically connects the first button 23 and the first processing unit 41. The first processing unit 41 and the drive control unit 120 are electrically connected by a third wiring 33. The drive control unit 120 and the bottom 70 are electrically connected by a wiring 35. For example, the third wiring 33 is provided within the cable 15.

When a first operation is performed on the panel 21, a first signal S1 corresponding to the first operation is input to the processing unit 41 via the first wiring 31. When the processing unit 41 receives the first signal S1, it outputs a second signal S2 for operating the bottom 70. The second signal S2 is sent to the drive control unit 120 via the third wiring 33. In response to the second signal S2, the drive control unit 120 drives at least one of the back bottom drive unit 71a, the knee bottom drive unit 71b, and the height drive unit 72 to operate the bottom 70.

When the first button 23 is pressed, a third signal S3 corresponding to this operation is input to the processing unit 41 via the second wiring 32. When the processing unit 41 receives the third signal S3, it outputs a fourth signal S4 for moving the bottom 70 from the first state to the second state. The fourth signal S4 is sent to the drive control unit 120 via the third wiring 33. When the drive control unit 120 receives the fourth signal S4, it drives at least one of the back bottom drive unit 71a, the knee bottom drive unit 71b, and the height drive unit 72 to move the bottom 70 from the first state to the second state.

By providing the first wiring 31 and the second wiring 32, even if a malfunction (e.g., a break) occurs in the second wiring 32, the first button 23 can be pressed to move the bottom 70 to the second state.

As shown in FIG. 4B, the operation unit 10 may include a first wiring 31, a second wiring 32, a third wiring 33, a fourth wiring 34, a first processing unit 41, a second processing unit 42 (e.g., a microcomputer), and a drive control unit 120. The first wiring 31 electrically connects the panel 21 and the first processing unit 41. The second wiring 32 electrically connects the first button 23 and the second processing unit 42. The third wiring 33 electrically connects the first processing unit 41 and the drive control unit 120. The fourth wiring 34 electrically connects the second processing unit 42 and the drive control unit 120. For example, the third wiring 33 and the fourth wiring 34 are provided in the cable 15.

In this example, when the first signal S1 is input, the first processing unit 41 outputs a second signal S2 for operating the bottom 70. The second signal S2 is sent to the drive control unit 120 via the third wiring 33. When the third signal S3 is input, the second processing unit 42 outputs a fourth signal S4 for operating the bottom 70. The fourth signal S4 is sent to the drive control unit 120 via the fourth wiring 34.

By providing the first processing unit 41 and the second processing unit 42, even if a malfunction occurs in the first processing unit 41, a signal can be sent from the second processing unit 42 to the electric bed 310.
