Description

  The present invention relates to an operation control device for an electric bed that controls an operation area of an electric bed that can move a back bottom, a knee bottom, and / or a height.

  The electric bed is a medical couch device that can be used to change the position of a bedridden patient and to assist a patient who can move up to some extent by driving the actuator, etc. It can be raised or lowered. In addition to medical beds, in general beds, there are also electric beds that can be raised and lowered so that the bed user can watch TV and read while lying on the bed. is there.

  In these electric beds, a back bottom, a waist bottom, a leg bottom, and the like are connected, and a mattress is laid on these bottoms. Normally, the back bottom is turned up in the direction of raising the back bottom, and the back bottom is turned up. In the lowering operation of lowering the back bottom, the back bottom is turned up. The waist bottom is normally fixed, and the leg bottom is driven up and down as the back bottom rises and descends.

  In this case, the movement area of the back bottom and the bed height can be set according to the physical condition (physique, physical condition, etc.) and physical ability (care level, rehabilitation progress, etc.) of each bed user. preferable. This makes it easy for the bed user to get up and stand up using his / her own power without depending on the operation of the bed, and the rehabilitation effect is promoted. The same applies to the knee bottom and bed height. Further, depending on the patient, the safety of life may be impaired unless the angle of the back bottom is maintained within a range of, for example, 10 ° to 30 °.

  As an operation control method of such an electric bed, there is one disclosed in Patent Document 1. The motion control method disclosed in Patent Document 1 is intended to allow a user (nurse or the like) to arbitrarily set an operation range (paragraph 0003). The position of one point or the desired movement range (upper limit and lower limit) is memorized by operating the bed up to that specific one point or upper limit and lower limit, and the normal operation button is the maximum movable range of the bed A normal operation is performed, and another button moves the bed (such as the back bottom) to the previously set and stored position, or moves the bed within the previously set and stored operation range.

  Further, the lifting control device disclosed in Patent Document 2 is intended to easily and quickly move a floor portion (back bottom, etc.) to a desired posture. First, the posture of the floor portion is detected. The detected information is stored in advance, the posture stored in the storage means is read out in a normal use state, and the floor is changed to the posture.

Japanese Patent No. 2874035 JP 10-33314 A

  However, in the motion control device for an electric bed described in Patent Document 1, a position to be stored (for example, a specific back raising position of the back bottom (a back angle corresponding to a posture that should always be), a back bottom motion range ( When the back bottom needs to be rotated once until the upper limit position and the lower limit position of the operating angle range), etc., and the position is memorized in that state. When a bed user such as a patient is sleeping on the bed The setting work when the caregiver sets is inconvenient, and there is a problem that the caregiver is burdened. Further, if the setting work is performed when the patient is sleeping on the bed, the posture of the patient changes, and the patient may be burdened.

  Furthermore, once the back bottom is rotated to the set position and the position is memorized, it is difficult to set a plurality of operation ranges. Setting the position for is difficult.

  Furthermore, as shown in FIG. 13, the prior art can control the operation only in one mode.

  The present invention has been made in view of such problems, and bed positions for complicated operations such as an operation range, a temporary stop position, and a plurality of operation ranges can be easily set without moving the bed itself. It is an object of the present invention to provide an operation control device for an electric bed that can be used for patient safety and can reduce the burden on the caregiver and the patient.

  The motion control device for an electric bed according to the first aspect of the present invention controls the electric bed that controls the motion of at least one motion member among the rotation of the back bottom relative to the frame, the rotation of the knee bottom relative to the frame, and the lifting and lowering of the frame. In the apparatus, an input unit for inputting a set value of the operating position of the operating member, a storage unit for storing a plurality of set values input from the input unit, and a driving device for driving the operating member are set to the set value. A control unit that controls the operation member based on one or a plurality of setting values of the plurality of setting values, and a temporary stop control at the setting values; and It is characterized in that at least one kind of control selected from the group consisting of operation range control with the set value as an upper limit value and / or a lower limit value is performed.

  In the present invention, a plurality of setting values input from the input unit are stored in the storage unit, and the control unit selects a setting value selected from the plurality of setting values when controlling the operation of the operating member. Based on this, at least one type of control selected from the group consisting of temporary stop and operation range control is performed. Therefore, when setting the set value, it is not necessary to move the operation member (back bottom, knee bottom, elevating frame, etc.) to the set position, and it can be set by an input operation from the input unit. Moreover, since the setting values from the input unit are stored in the storage unit, a plurality of setting values can be easily set, and the control unit can operate the operating member based on the setting values selected from these setting values. Can be controlled.

  Another motion control device for an electric bed according to the second invention of the present application is an electric bed for controlling the motion of at least one motion member among the rotation of the back bottom relative to the frame, the rotation of the knee bottom relative to the frame, and the lifting and lowering of the frame. In the control apparatus, an input unit that inputs a setting value of the operation position of the operation member together with a designation operation of the operation member, a storage unit that stores a plurality of setting values input from the input unit, and the operation member And a control unit that controls the drive device that drives the control unit based on the specified operation and the set value. The control unit causes the operation member to perform an operation based on the specified operation, and Based on one or more set values in the set value, select from the group consisting of temporary stop control at that set value and operation range control with the set value as the upper limit value and / or lower limit value And performing at least one control that.

  In the present invention, in addition to the first invention, the input unit also inputs a designation operation for designating the operation of the operation member such as raising and lowering the back bottom. Then, the control unit performs the specified operation restricted by the set value based on the specified operation and the set value input from the input unit. For example, when the designated operation is raising the back bottom and the set value is within the rotation angle range of the back bottom, the control unit controls the drive device to raise the back bottom and sets the upper limit of the back angle. When the back angle rises to the set value, the drive device is controlled so as to stop the drive of the back bottom. Then, when the lowering of the back bottom is designated, the control unit controls the drive device to lower the back bottom, but when the back angle is lowered to the set value of the lower limit value of the back angle, The drive device is controlled to stop the bottom drive. In this way, the operation range of the back bottom is controlled.

  In this case, the input unit includes: an input button that performs common input of the specified operation of the operating member and input of a set value related to the specified operation; and input of the specified operation and input of the set value It is preferable to have a selection button for selecting one.

  By doing in this way, in an input part, it is not necessary to provide an input button separately for several designation | designated operation | movement and several setting values, and the structure of an input part is simplified.

  According to the present invention, it is possible to set a desired set value without moving the motion member (back bottom, knee bottom, lifting frame, etc.) of the bed, so even when the patient is sleeping on the bed The set value can be easily changed, and the setting work when the caregiver sets is easy, so that the caregiver is not burdened.

  In addition, according to the present invention, it is possible to easily set a plurality of set values, to easily set a plurality of operation ranges, and to set a plurality of positions to be temporarily stopped. The position setting for is easy.

  As a result, the motion area of the back bottom, the motion area of the knee bottom, and the motion of the bed height according to the physical condition (physique, physical condition, etc.) and physical ability (degree of care, rehabilitation progress, etc.) of each bed user Areas and the like can be set, and independence support by promoting the rehabilitation effect of the care recipient and the burden on the caregiver can be easily reduced.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings. FIG. 1 is a schematic diagram showing an outline of an embodiment of the present invention. As shown in FIG. 1A, for example, the back bottom rotates from its horizontal position (falling state) to its standing position (rising state), but the maximum standing position is the mechanism of the electric bed. Is the upper limit of operation. In the present embodiment, a plurality of setting positions are stored in the storage unit between the horizontal position and the operation upper limit value. This set value may be defined as the back angle of the back bottom (angle formed with the horizontal state), or may be defined as the advance length of the piston of the actuator that drives the back bottom. In the use state of the electric bed, as shown in FIG. 1 (b), two setting values are selected from the plurality of setting values, and the two setting values are set to the upper limit value and the lower limit value. The operating range of the back bottom is set as a value, and the back bottom is controlled so that the back bottom rotates within this range. In this case, as shown in FIG. 1 (c), two operating ranges of the back bottom may be set, or three or more may be set. As a result, when there are a plurality of bed users, the operation range can be individually set according to the state of each of the plurality of people, and even if there is only one bed user, the body A plurality of operation ranges may be used in order to change the operation range according to the situation or time zone. Further, as shown in FIG. 1D, the set value can be temporarily set to the stop position. For example, when an operation of rotating the back bottom in the upward direction from the horizontal state is performed, the back bottom is temporarily stopped at the position of “Temporary stop 1”. Thereafter, the operator (usually a caregiver) decides whether to return the back bottom to a horizontal state or to rotate the back bottom in a direction in which the back angle is further increased, and performs an operation for that purpose. When an operation for moving the back bottom in the direction to stand is performed, the back bottom stops at the position of “temporarily stop 2” unless a stop operation is performed thereafter. Next, the operator decides whether to further rotate the back bottom in the raising direction, stop it, or lower it. In the case of FIG. 1D, the back bottom can be operated between “Temporarily Stop 1” and “Temporarily Stop 2”, so that the operating range is set as in FIG. 1B. In addition to being set, when the back bottom is in a horizontal position for the patient's medical care or when the back bottom is set to the upper operation limit value (maximum standing position) for the patient to move on the bed, By temporarily stopping at the stop position, the caregiver can be informed of the position and used to call attention. Thereby, the convenience on the operation surface is increased.

  Next, the operation control apparatus according to the embodiment of the present invention will be specifically described. FIG. 2 is a front view showing an electric bed in which the operation control apparatus according to the embodiment of the present invention is incorporated. The base frame 1 includes a pair of vertical bars extending in the bed longitudinal direction and at least one pair of horizontal bars connecting the vertical bars. On the pair of vertical bars of the base frame 1, the first link 3a and the first link An X-shaped link mechanism in which the two links 3b are connected to each other by a rotating shaft 3c is provided. And the raising / lowering frame 2 is installed on this X-shaped link mechanism. Similarly to the base frame 1, the elevating frame 2 is also composed of a pair of vertical bars extending in the bed longitudinal direction and at least a pair of horizontal bars 2a connecting the vertical bars to each other. The lower end of the first link 3a is rotatably connected to the vertical bar of the table frame 1 by a rotary connecting portion 4a, and the upper end of the second link 3b is a rotary connecting portion (not shown) to the vertical bar of the elevating frame 2. It is connected so that it can rotate. Further, the upper end of the first link 3a is supported by a slide connecting portion 4b provided on the vertical bar of the elevating frame 2 so as to slide slightly in the bed longitudinal direction and to rotate. The lower end of the second link 3b is also supported by the vertical bar of the base frame 1 so as to be rotatable and slidable by a slide connecting portion (not shown). A base portion of the actuator 40 is rotatably connected to and supported by the elevating frame 2, and a piston 40 a is rotatably connected to a link 42 connected to the rotating shaft 3 c by a rotation fulcrum 41. Thus, when the piston 40a advances by driving the actuator 40, the rotating shaft 3c is pressed to the bed head side (left side in FIG. 1), and the angle formed above and below the first link 3a and the second link 3b becomes small. The first link 3a and the second link 3b are rotated so that the width of the X link is narrowed, and the elevating frame 2 is raised. On the other hand, when the piston 40a of the actuator 40 is retracted, the first shaft 3a and the second link 3b are rotated so that the rotation shaft 3c is pulled toward the leg portion of the bed and the width of the X link is widened, and the lifting frame 2 goes down.

  A pair of vertical bars of the elevating frame 2 is provided with a support portion 10 for the back bottom 12, and a rotating shaft 11 (rotation fulcrum) of the back bottom 12 is provided on the upper portion of the support portion 10. Yes. The rotating shaft 11 is positioned above the back bottom 12 when the back bottom 12 is in a horizontal state. The back bottom 12 is fixedly connected to a base end portion of a link (not shown) so that an angle formed between the back bottom 12 and the link is unchanged, and the other end of the link is connected to the rotating shaft 11. It is rotatably supported. The back bottom 12 is composed of a pair of bars and a plurality of (three in the illustrated example) support plates 13a, 13b, 13c installed on the bars. The pair of bars are arranged in the vicinity of the vertical bar of the frame 2, and the pair of bars of the back bottom 12 are fixed to one connecting shaft (not shown). Then, both end portions of the connecting shaft are fixed to one end portions of the pair of links.

  Further, a support shaft 16 of the actuator 14 is fixed to the lifting frame 2, and a bracket 15 is fixed to the support shaft 16, and a base portion of the actuator 14 is rotatably connected to a lower portion of the bracket 15, It is supported. The piston 14 a of the actuator 14 is rotatably connected to the distal end portion of the back bottom 12 via the rotation shaft 17. As a result, when the piston 14a of the actuator 14 advances, the piston 14a pushes up the back bottom 12 to rise, and the back bottom 12 rotates about the rotation shaft 11 as a rotation center. On the other hand, when the piston 14a of the actuator 14 is retracted, the piston 14a pulls back the back bottom 12, and the back bottom 12 returns to the horizontal position. Thereby, a back raising operation and a back lowering operation are performed. In this case, the rotary shaft 11 is positioned above the back bottom 12 when the back bottom 12 is in the horizontal position. Therefore, the back bottom 12 rotates using the rotary shaft 11 provided above as a rotation fulcrum. .

  On the other hand, on the elevating frame 2, a knee bottom 22 and a leg bottom 23 are rotatably connected to each other by a connecting shaft 24. The knee bottom 22 is rotatably connected to a support portion 20 installed on the frame 2 by a rotation shaft 21. The knee bottom 22 and one end of the link 26 are rotatably connected by a rotating shaft 33, and the other end of the link 26 and the frame 2 are rotatably connected by a rotating shaft 28. Further, the leg bottom 23 and one end of the link 27 are rotatably connected by a rotating shaft 25, and the other end of the link 27 and the frame 2 are rotatably connected by a rotating shaft 29. Further, one end portion of the link 32 is rotatably connected to the intermediate portion of the link 26. An actuator 30 is fixed to the frame 2, and the tip of the piston 30 a of the actuator 30 is connected to the other end of the link 32 via a rotating shaft 31. As a result, when the piston 30a of the actuator 30 advances, the link 32 connected via the rotary shaft 31 pushes up the link 26 and rotates the link 26 upward about the rotary shaft 28. As a result, the knee bottom 22 rotates in the direction of rising around the rotation shaft 21, and the leg bottom 23 also moves upward in conjunction therewith. Since both ends of the leg bottom 23 are linked in a chain form by the knee bottom 22, the link 26, the portion between the rotation shafts 28 and 29 of the frame 2 and the link 27, the length of these chain-like parts. Is appropriately set, the leg bottom 23 can be raised while maintaining the horizontal state when the leg bottom 23 rotates in the direction in which the knee bottom 22 rises. When the knee bottom 22 is rotated in the horizontal direction, the leg bottom 23 descends and returns to the position of the frame 2, and the knee bottom 22 and the leg bottom 23 become horizontal.

  A waist bottom (not shown) is fixed horizontally at a position between the back bottom 12 and the knee bottom 22 in the frame 2. Therefore, when the back bottom 12 and the knee bottom 22 are in a horizontal state, the back bottom 12, the waist bottom, the knee bottom 22 and the leg bottom 23 are positioned on the same horizontal plane. When the back bottom 12 and the knee bottom 22 are lifted, the waist portion of the bed user is held as it is by the stationary waist bottom.

  In such an electric bed, the operation control apparatus of the first embodiment of the present invention includes a hand switch 50 for designating the operation of the electric bed and a bed controller 51 as shown in FIG. Controls the actuator 52, and the actuator 52 drives the bed. As shown in FIG. 5, the hand switch 50 includes “up” and “search” buttons for “Atama”, “up” and “search” buttons for “Ashi”, and “up” and “search” for “Takasa”. "Button is provided, and further, a" setting "button is provided. “Atama” is an operation button on the back bottom, and “Ashi” is an operation button on the knee bottom. “Takasa” is the height of the bed and is a button for raising and lowering.

  As shown in FIG. 3, the hand switch 50 is provided with an input signal detection unit 53 for detecting a signal of an input operation when each of the buttons is pressed, and this detection signal is transmitted to the controller via a communication line. 51 is input to the input / output signal receiving unit 55, and further input from the input / output signal receiving unit 55 to the control unit 57. On the other hand, a signal from the control unit 57 of the controller 51 is input to the liquid crystal display unit 54 of the hand switch 50 via the input / output signal receiving unit 55, and the operation content is displayed. The control unit 57 inputs and stores the setting value input from the hand switch 50 in the storage unit 56 and controls the actuator 52 based on the setting value read from the storage unit 56. That is, the control unit 57 outputs a control signal to the motor unit 59 of the actuator 52, rotates the motor unit 59, and advances and retracts the piston of the actuator 52 to drive the bed. The actuator 52 is provided with a position information detection unit 58 including a sensor unit for detecting the position of the piston or the rotational position of the motor. The position information detection unit 58 is a position of the piston or motor detected by the sensor unit. The position information of the back bottom and the like is detected from the rotation position, and this position information is input to the control unit 57 via the input / output signal receiving unit 55 of the controller 51 and used for feedback control of the position of the back bottom and the like.

  Next, the operation of the operation control apparatus of this embodiment will be described. First, the case where the operation range in FIG. 1B is set will be described. FIG. 6 is a flowchart of the setting value setting operation. The setting button of the hand switch is pressed to move the operation of the hand switch 50 to the setting mode. Then, even if each button of the hand switch 50 is pressed until this setting mode is canceled, the bed does not operate and the setting value can be changed. At this time, the previous set value read from the storage unit 56 is displayed on the display screen of the hand switch 50. Furthermore, when the setting button is pressed, and then the “up” button of “Atama” is pressed, the back angle setting value of the back bottom increases by + A ° (A is an angle change amount), and this is a hand switch. 50 display screens. The input operation is detected by the input signal detection unit 53, and the set value is input to the control unit 57 via the input signal reception unit 55 and stored in the storage unit 56. The setting value of the back angle of the back bottom is set to a desired value by repeating the pressing of the “raising” button a plurality of times or by continuing to press the “raising” button. When the “Search” button of “Head” is pressed, the setting value of the back angle is lowered by −A ° and displayed on the display screen. Therefore, when the initial value of the back bottom when the setting button is pressed is higher than the value to be set, the setting value of the back bottom is set by pressing this “search” button. For the knee bottom, the knee angle is changed by B (B is the angle change amount) by pressing the “raise” button or the “raise” button of “Ashi”, and the knee bottom knee angle setting value is Is set. Further, with respect to the bed height (frame height), the bed height is changed by C (C is the height change amount) by pressing the “rise” button or the “search” button of “Takasa”. The set value of the bed height is set. After all the setting values are set, the setting button is pressed, and these setting values are stored in the storage unit 56 as one set. Thereafter, by repeating the above operation, a plurality of sets of setting values are stored in the storage unit 56. By providing a storage unit in the hand switch 50, the set value of the set is temporarily stored in the storage unit of the hand switch 50. The data may be transferred from the storage unit to the storage unit 56 of the controller 51. Further, the amount of change (setting interval) of A, B, and C can be arbitrarily determined.

  After completing the setting, pressing the setting button releases the setting mode and shifts to the normal operation mode. First, out of a plurality of set values set as described above, two set values are set as an upper limit value and a lower limit value, and the operation range is controlled between the upper and lower limit values. The selection of the upper limit value and the lower limit value and the selection of the operation mode (FIG. 1B, etc.) are performed using another button (not shown) provided on the hand switch 50. As shown in FIG. 11, when a plurality of positions are set, an upper limit value and a lower limit value are selected from stored setting values. When there is one set value, it is set to the upper limit value or the lower limit value. When this is set as the upper limit value, the lower limit value is the minimum value of the angle or height. Further, when one set value is set as the lower limit value, the upper limit value is set as the operation upper limit value of the angle or height.

  The caregiver or the bed user operates the bed in this normal mode. FIG. 8 is a flowchart when the bed is operated using the hand switch 50 in the normal operation mode. Then, for example, when the “Up” button of “Atama” on the hand switch is pressed, the back bottom rotates upward, and this raising operation is performed until the current position of the back bottom matches the set upper limit value. The bed stops when the upper limit is reached. The same applies when the “search” button is pressed, and the back bottom moves down to the lower limit. The same applies to the knee bottom and bed height.

  As shown in FIG. 8, for example, when the bed height is in the operation range between the upper and lower limit values, when the “go up” button is pressed or when the “go down” button is pressed, it is shown in FIG. The bed frame moves up and down according to the flowchart. That is, when the “go up” button is pressed, the current position is higher than the lower limit value, so that the bed is moved up. Then, when the current position reaches the upper limit value, the bed is stopped. However, if the current position is less than or equal to the lower limit value, the process ends. On the other hand, when the “search” button is pressed, the current position is lower than the upper limit value, so that the bed is moved downward. Then, the bed is stopped when the current position reaches the lower limit value. However, if the current position is greater than or equal to the upper limit value, the process ends.

  Thus, in this embodiment, the set values of the back angle, knee angle, and / or bed height can be stored without operating the bed. Therefore, even when the patient is in bed, a third party such as a caregiver can store and set the position. And since a setting value can be set according to a bed user's physical condition, the burden of a caregiver is reduced. In addition, it is possible to manage the physical condition of the bed user and information such as the back angle, knee angle, and bed height setting values, making it easy to grasp the progress of rehabilitation, etc. Convenience in information management is improved.

  Next, when a plurality of operation range areas are set as shown in FIG. 1C, if a plurality of areas are set as shown in FIG. 10, an area to be activated is selected from the areas. Set the area. Thereafter, the bed operation is performed as shown in FIG.

  Thus, according to the present invention, since a plurality of operation range areas can be set, a suitable movable area can be set according to the physical condition and time zone of the user on that day. For example, a wide operating range is set in the morning, and a narrow operating range is set in the daytime. Also, if you are in good physical condition, set the lower back angle upper limit value lower to encourage you to stand up on your own, and if you are not healthy, set the upper back angle upper limit value higher and use the bed motion And can encourage you to get up. Thus, many patterns can be set according to a physical condition, a time slot | zone, etc. by the method of selection of an upper limit and a lower limit.

  Next, as shown in FIG. 1D, when the set value is temporarily set to the stop position, for example, when the “Up” button of “Atama” is pressed, as shown in FIG. The bottom is rotated so as to rise to stop 1 or stop 2 (see FIG. 1D). When the “go up” button is pressed again, the spine bottom rises to the upper stop 2 or the upper limit of operation and stops. On the other hand, when the “Search” button of “Head” is pressed, the back bottom is rotated so as to be temporarily lowered to Stop 1 or Stop 2 as shown in FIG. In either case, the back bottom is stopped by the temporary stop 1 or the temporary stop 2. When the same button is pressed again after stopping, the back bottom moves down to the lower temporary stop 1 or the horizontal position and stops at that position.

  When the set value is used as the temporary stop position shown in FIG. 1D, the operation control in the operation range between the temporary stop 1 and the temporary stop 2 is performed with one button (similar to FIG. 1B). It is possible to set the back bottom in the range up to the horizontal position outside the operating range and the range up to the operating upper limit value, and in the region from the horizontal position to the operating upper limit value, There is an advantage that the operation can be controlled. And by setting the stop position once, it can be used as a guideline for the position of the bed user to stand up, and in the case of cleaning etc., it can be moved from the horizontal position to the operation upper limit value. Convenience in operation is improved. In addition, in the case of a bed user with a high degree of recognition, once the stop position is set, it becomes a function of notifying that the bed is set to this position, and assisting to stand up by one's own power. In addition, the rehabilitation effect is promoted.

  Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, the setting value is not set by the hand switch 50 but is set by the personal computer (hereinafter referred to as a PC) 60. By inputting the setting value to the PC 60, the setting value is stored in the storage unit 64 by the control unit 63 of the PC 60 and displayed on the liquid crystal display unit 65. Then, after one or more sets of setting values are set on the PC 60, the setting values are input to the controller 51 via the communication line, and the setting values are transferred to the storage unit 50.

  In the second embodiment, as shown in FIG. 7, the previous set value of each part is displayed as an initial value on the liquid crystal display unit 65 of the PC 60. And the setting value of each part is input using the input device of PC60. Then, after all the parts have been input, a setting completion operation is performed, and the setting value is stored in the bed controller 51.

  In addition to the same effects as the first embodiment, this embodiment has the advantage that the setting value setting operation is easy.
