Description

The present invention relates to a bed operating device.

Conventionally, beds used by users such as patients and caregivers include beds used for treatment purposes in hospitals and the like (hereinafter referred to as hospital beds) and beds used for nursing care purposes in nursing care facilities and homes (hereinafter referred to as hospital beds). There is a nursing bed).

Unlike hospital beds, nursing beds are required to be small and lightweight due to restrictions on the installation location. In addition, considering the ease of carrying in and installing, it is common that the bed is divided into parts so that it can be easily assembled and disassembled.

In addition, there is known a technology that allows the height of the bed device to be changed, such as raising the bed device to a low position so that the user can easily transfer from the bed device, or raising the bed device to a high position so that the user can easily provide nursing care. (See, for example, Patent Document 1).

Further, in the case of a nursing bed, the user may operate it by himself or the caregiver may operate it, but both the user and the caregiver may be unfamiliar with the operation. Therefore, in order to prevent inadvertent erroneous operation, a bed device in which a power button is mounted on a hand switch is known (see, for example, Non-Patent Document 1). By operating the power button, it is possible to lock (prohibit) the operation in the standby state. That is, in the standby state, the operation by the operation button which is the operation input means is prohibited.

The lower ends of the elevating portions 14H and 14F are detachably connected by the connecting frame 18. The connecting frame 18 has a pair of pipe-shaped frame structures, and exhibits a structure in which the length direction of the connecting frame 18 is aligned toward the head side and the foot side.

A drive device (for example, an actuator) is provided in each of the elevating portions 14H and 14F, and the driving force of each actuator is controlled separately. By controlling the drive of each actuator, the upper ram can be tilted so that there is a difference in the vertical position between the head side and the foot side.

[2. Functional configuration]
Subsequently, the functional configuration of the bed device 1 in the present embodiment will be described with reference to the drawings. FIG. 3 is a diagram for explaining the outline of the functional configuration of the bed device.

In the bed device, the drive control unit 200, the state detection unit 300, the storage unit 400, and the operation display unit 500 are connected to the control unit 100, respectively.

The control unit 100 is a functional unit for controlling the entire bed device. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 400, and is composed of, for example, a CPU (Central Process Unit) or the like.

The drive control unit 200 is a functional unit for controlling a drive unit (drive device, an actuator in the case of this embodiment) provided in the bed device. The drive control unit 200 is provided in the bed device as, for example, a control unit or the like.

The drive control unit 200 will be described with reference to FIG. As shown in FIG. 4, the drive control unit 200 includes a bottom control unit 210 for controlling back-raising, knee-raising (foot-lowering) functions, etc. by operating the bottom, and the height of the bed device. The function with the height control unit 220 that controls the above is realized.

In order to realize the back raising function, the back bottom driving unit 212 and the knee bottom driving unit 214 are connected to the bottom control unit 210. The back bottom drive unit 212 is the actuator 36 in FIG. 2, and is connected to the back raising link 20 via a link mechanism. Then, under the control of the back bottom drive unit 212, the back bottom 42 mounted by the link 20 operates, and back raising / back lowering control is performed.

Further, the knee bottom drive unit 214 is the actuator 38 in FIG. 2, and is connected to the link 22 for raising the knee via a link mechanism. Then, by controlling the knee bottom drive unit 214, the knee bottom 46 mounted on the link 22 and the further connected foot bottom 48 operate, and knee raising / knee lowering (foot lowering / foot raising) control is performed. Will be.

In addition, the upper body of the user P is supported by the back bottom 42, and the waist portion is supported by the waist bottom 44. Further, by abutting and supporting the knee bottom 46 and the thigh portion of the user P, it is possible to prevent, for example, the user P from moving in the foot side direction F.

The height control unit 220 controls the height of the bed, and the head side drive unit 222 and the foot side drive unit 224 are connected to each other. The head-side drive unit 222 is the actuator 32 in FIG. 2, and realizes the elevating function of the elevating unit 14H. Further, the foot-side drive unit 224 is the actuator 34 in FIG. 2, and realizes the elevating function of the elevating unit 14F. By controlling the head side drive unit 222 and the foot side drive unit 224 by the same amount of control (that is, the heights of the elevating part 14H and the elevating part 14F are the same), the horizontal state is maintained. While it is possible to change the height of the bed device.

Further, by controlling the head side drive unit 222 and the foot side drive unit 224 by different control amounts (that is, the heights of the elevating part 14H and the elevating part 14F are set to different heights), the bed device is tilted. The operation can be realized and the bed can be tilted.

The state detection unit 300 is a functional unit for detecting the state of the entire bed device. For example, it detects the state of the bed device (whether or not the back is raised, etc.), detects the current height of the bed device, detects whether or not the user is currently on the bed device, and the like. Can be done.

The state detection unit 300 may detect using various sensors, or may detect based on a signal received by the actuator. For example, when detecting the back-raising angle, the correlation between the amount of operation of the actuator 36 (the amount of the extended rod) and the back-raising angle is stored in advance. Thereby, by detecting the current state of the actuator 36, the back-raising angle raised by the actuator 36 can be detected.

Further, the correlation between the amount of operation of the actuator 32 (34) and the elevating portion 14H (14F) is stored in advance. This makes it possible to detect the current height and tilt angle of the upper frame 10.

For convenience of explanation, the state detection unit 300 will detect various states, but the control unit 100 may perform all of them.

The storage unit 400 is a functional unit that stores various programs and various data necessary for operating the bed device. The storage unit 400 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

The operation display unit 500 is a functional unit that inputs operations to the bed device 1 (bed device main body 3), and realizes back-raising / knee-raising (foot-raising) functions and adjusts the height of the bottom. The function to do is realized. Further, as the current state of the bed device main body 3, the back raising angle, the height of the bed, the current operation mode, and the like are displayed. The operation display unit 500 is the bed operation device 5 in FIG.

Here, the bed operation device 5 (operation display unit 500) will be described with reference to FIG. As shown in FIG. 5, the bed operation device 5 includes a display unit 510 and an operation button 520 as an operation input means.

The display unit 510 displays various information such as the current operating status and the bed status. For example, it is composed of a liquid crystal panel, an organic EL panel, and the like.

Further, the operation button 520 is a functional unit (operation input means) for instructing the bed device main body 3 to operate various operations. For example, in the present embodiment, the "interlocking" in which the back raising and the leg raising are performed together, the "head" in which the back raising operation is performed, the "foot" in which the knee raising (foot lowering) operation is performed, and the bed device main body 3 For the "height" that changes the height (elevation operation), "up" and "down" operations can be performed, respectively.

For example, when the user wants to perform the back-raising operation, the user selects (presses) the button 522. Further, when the user wants to perform the back lowering operation, the user selects (presses) the button 524.

Further, in the present embodiment, the power lamp 530 is provided. When the power lamp 530 is lit, the power is turned on, that is, the bed device can be operated by selecting the button 522.

The state in which the power is turned on is a state in which the bed device main body can be operated in the energized state. It suffices if this makes it possible to control "a state in which the bed can be operated" and "a state in which the bed cannot be operated". That is, not only the power is turned on, but also various operations may be restricted by an operation lock or the like.

[3. Process flow]
The processing in this embodiment will be described with reference to FIG.

First, the power supply is in the standby state (step S102). Here, the standby state means, for example, a case where the power is supplied via the power cable but the operation is not possible. That is, the bed operation is restricted by the user.

Subsequently, it is detected whether or not the button is selected (step S104). Specifically, it detects that any of the buttons 522 is selected. At this time, only one button may be detected. That is, when two or more buttons are detected, the buttons may not be detected as the selected state.

Subsequently, when it is detected that the button selection state has been released (step S106; Yes), the power is turned on (step S108). That is, the power is turned on (that is, the operable state) at the timing when the button 522 is selected and the selection of the button 522 is released. For example, at this time, the power lamp 530 is turned on to notify the user that the power is turned on, or the display unit 510 is displayed to notify the user that the power is turned on. do.

Subsequently, when it is detected that the button has been selected from this state, the operation corresponding to the selected button is executed (step S110; Yes → step S112).

It is determined whether or not a predetermined time has elapsed in a state where the button is not selected (step S110; No) or when the operation is completed (step S114).

Here, if the predetermined time has not elapsed, the process is repeatedly executed from step S110, and if the predetermined time has elapsed, the power supply is transitioned to the standby state (step S114; Yes → step S102).

Here, the predetermined time is a time for the power supply to transition to the standby state, and may be a preset time or may be arbitrarily set by the user. Further, as the elapsed timing of the predetermined time, the time during which the no-operation state normally continues (that is, the time during which steps S110; No → step S114; No → step S110; No → ... Is repeated) has elapsed for a predetermined time. Judge whether or not.

Further, the start time of whether or not the predetermined time has elapsed may be the time when the above-mentioned non-operation state continues. In this case, once the operation is executed in step S112, the timer is reset at that timing.

[4. Operation example]
A specific operation example will be described. For example, FIG. 7 is a state transition diagram of the present embodiment. First, when the main power is turned on (turned on separately by the main power operation switch, the power cable is connected to the outlet, etc.) from the OFF state (state not connected to the power supply, etc.), it goes into the standby state. Transition. Further, when the main power supply is turned off from the standby state (turned off separately by the main power supply operation switch, the power cable is disconnected from the outlet, etc.), the state transitions to the OFF state.

In the standby state, the operation button is selected and the selected state is released, so that the ON state is entered. In the ON state, the ON state is maintained as long as the operation is performed. Here, if a predetermined time elapses without any operation, the state transitions to the standby state.

Further, when the main power supply is turned off (separately turned off by the main power supply operation switch, the power cable is disconnected from the outlet, etc.) in the ON state, the state transitions to the OFF state.

In this way, from the OFF state to the operation, the state always transitions to the standby state and then to the ON state. Further, in order to transition from the standby state to the ON state, the button is selected and turned ON at the timing of releasing the button, so that it is possible to prevent the bed device main body from operating due to an erroneous operation.

Further, since the power can be turned on by the operation button instead of the power button, it is possible to provide an operation that is easy for the user to understand.

As described above, in the present embodiment, the restriction that the bed can be operated in the ON state is released. In addition, the operation of the bed is restricted in the standby state. Further, in the OFF state, the operation cannot be performed because the power is not supplied.

FIG. 8 is a diagram schematically showing a part of the bed operating device 5. FIG. 8 shows a state in which the power of the bed device is not turned on (standby state). At this time, the user selects the operation button 526.

FIG. 9 is a diagram showing a state in which the selected state of the operation button 526 selected in FIG. 8 is canceled. When the operation button 526 changes from the selected state to the released state, the power is turned on. Here, "ON" is displayed on the display unit 510, and the power lamp 530 lights up.

FIG. 10 is a diagram in which the operation is possible. From this state, the button 526 is selected again in FIG. The back-raising operation is executed. For example, in FIG. 10, the back-raising angle is "60" degrees, but in FIG. 11, it is "65" degrees.

Further, FIG. 12 shows a state in which the operation of the bed device is locked. Therefore, "operation locked" is displayed on the display unit 510. At this time, the user selects the operation button 526.

FIG. 13 is a diagram showing a state in which the selected state of the operation button 526 selected in FIG. 12 is canceled. When the operation button 526 changes from the selected state to the released state, the lock is released and the operation becomes possible. Here, "released" is displayed on the display unit 510, and the operable lamp 535 lights up.

[5. Other Examples]
Next, another embodiment will be described. In the above-described embodiment, it has been described that the power is turned on (becomes operable) when the operation button is selected and released.

Here, an example will be described in which the power is turned on (operable) at the timing when the button is selected for a predetermined time or longer when the first operation button is selected and then released. ..

Specifically, in step S104 of FIG. 6, the timing of detecting the button selection may be set to the time when a predetermined time has elapsed. For example, when the predetermined time is "3 seconds", if the selected state of the button is maintained for 3 seconds (for example, when the button is held down for 3 seconds), the button may be detected as selected.

As a result, for example, when the power is turned on (operable), it is necessary to keep selecting the same operation button for a predetermined time or longer. Therefore, it is possible to provide a bed operation device with higher safety.

Also, turning on the power means that it is in an "operable state". Therefore, even if the button is selected and then released to the operable state, the same effect will be obtained.

That is, as shown in FIG. 14, the power may be turned on in a state (pressed state) in which an arbitrary button (for example, a button to be operated) is selected in the "standby state". However, no other operation can be performed in this state. That is, when this selected state is released, the state transitions to the "operable state" and various operations can be performed.

Then, when a predetermined time elapses in the "operable state", the transition to the "standby state" may occur again. As described above, it is possible to provide a highly convenient and highly safe bed operation device by preventing the user from having to bother to operate the power button and preventing erroneous operation.

[6. Modification example]
Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and the design and the like within a range not deviating from the gist of the present invention are also within the scope of claims. include.

Further, in the above-described embodiment, it has been described that the bed operation device 5 has a display unit 510, an operation button 520, and a power lamp 530, but it may be integrally formed by, for example, a touch panel or the like.

Further, the bed operation device 5 may be a wireless connection instead of a wired connection, or may be realized by another device such as a smartphone or a tablet. Specifically, it may be realized by installing an operation application on a smartphone (tablet) and connecting the bed device to the bed device using an IP network or the like.
