Description

[Technical field]

[0001] The present invention relates to a nursing bed used for providing nursing care to a person receiving care. [Background technology]

[0002] Patent Document 1 proposes a turning-over assist bed that includes a head frame with a tiltable floor surface, a movable stage for moving the head frame, and a fixed stage that supports the movable stage via rollers attached to the movable stage. The fixed stage includes lifting units on the left and right sides that raise and lower the movable stage. The sides of the movable stage are raised and lowered by the lifting units, and the rollers roll inward and tilt accordingly. In addition, a tension spring is attached to the lifting units to apply a load in a direction that reduces the tilt of the movable stage.

[0003] Patent Document 2 proposes a nursing bed comprising a head frame main body having two stand frames with extendable feet, a foot connecting frame connecting the feet of the two stand frames, a stand connecting frame connecting the two stand frames, and an up-and-down movable frame member equipped with an up-and-down movement drive means for moving the stand connecting frame up and down, a foot frame main body similar to the head frame main body, a head-foot connecting member that faces both frame main bodies, two hanging members suspended from a hanging shaft connected to the up-and-down movable frame members of the opposing head frame main body and foot frame main body so as to be rotatable about a virtual axis connecting both hanging shafts, a bed main body suspended by the two hanging members, an inclination control member that controls the rotation of the hanging members, and a bathtub arranged below the bed main body.

[0004] Patent Document 3 proposes a nursing bed that includes a main bed, a right sub-bed, a left sub-bed, and a base 4. When the first front rotation mechanism, the first rear rotation mechanism, the second front rotation mechanism, and the second rear rotation mechanism are driven, the first and second central wires are pulled, and the first and second right and first and second left wires are loosened, the main bed rotates around the shaft of the left hinge as the center of rotation, the right sub-bed rotates upward to a right inclined position due to the bias of the right leaf spring, and the left sub-bed rotates upward to a left inclined position due to the bias of the left leaf spring.

[0005] [Patent Document 1] JP 2004-97240 A [Patent Document 2] JP 2009-89860 A [Patent Document 3] JP 2020-10822 A Summary of the Invention [Problem to be solved by the invention]

[0006] The beds proposed in Patent Documents 1 to 3 are designed to be inclined as a whole bed, so that the caregiver can easily provide care. Specifically, it is considered that the bed can be used when the care recipient turns over in sleep or changes position. However, in the field of care, the care recipient often stands up from a lying position on the bed with the help of the caregiver or by himself / herself. The beds proposed in Patent Documents 1 to 3 are not designed with such a usage mode in mind, and if the bed is inclined to help the care recipient stand up from a lying position on the bed, the possibility that the care recipient may fall off the bed cannot be denied.

[0007] The present invention has been made in consideration of these problems, and provides a nursing bed that enables a cared-for person to easily raise his / her upper body from a lying position on the bed and stand up on the floor or the like. [Means for solving the problem]

[0008] The invention for solving the above problem includes a floor body having a first support part for supporting the lower body and a second support part for supporting the upper body, the floor body being divided into at least the first support part and the second support part in the width direction of the floor body. ,before the first support portion is a movable body that can rotate about a rotation axis extending along the longitudinal direction of the floor body; the second support portion is a movable body that can rotate about the rotation axis line, the first support portion and the second support portion can rotate about the rotation axis line independently of each other, and the rotation axis line is located above the first support portion and the second support portion; It is a nursing bed equipped with:

[0009] According to this configuration, the inclination angle of the first support part can be freely set, so that the lower body can be inclined by inclining the first support part, thereby enabling the care recipient to easily place the lower body on the floor and stand up. Also, according to this configuration, the inclination angles of the first support part and the second support part can be freely set, so that, for example, by making the inclination angle of the first support part larger than that of the second support part, the lower body can be inclined more than the upper body. This allows the care recipient to easily raise the upper body and stand up without feeling that they are falling off the bed. Furthermore, according to this configuration, since the rotation axis is located above the first support part and the second support part, the bed has a mechanism that swings like a hammock. Therefore, when the bed rotates, the care recipient on the bed is supported in a state where he or she is pressed against both support parts. This allows the care recipient to avoid anxiety that he or she may fall off the bed.

[0010] Note that the "lower body" refers to the area from the thighs down, and does not necessarily include the buttocks. Also, the thighs do not have to be included in their entirety, but may include only a part of the thighs.

[0011] Note that the "upper body" refers to the area from the back up, and does not necessarily include the waist and buttocks. Also, the back does not have to be included in its entirety, but only a part of it.

[0012] N The terms relating to rotation about a rotation axis include clockwise and counterclockwise rotation.

[0016] Preferably, the actuator includes a first drive portion that rotates the first support portion about the rotation axis, and a second drive portion that rotates the second support portion about the rotation axis.

[0017] According to this configuration, the bed is provided with a first drive unit that rotates the first support part about a rotation axis, and a second drive unit that rotates the second support part about a rotation axis, thereby improving rotation functionality and allowing the caregiver or the person being cared for to easily rotate the bed.

[0018] Preferably, the driving device further comprises a control unit which generates a control signal for instructing the operation of the first driving unit and the second driving unit, and outputs the control signal to the first driving unit and the second driving unit.

[0019] According to this configuration, a control unit is provided that commands the operation of the first drive unit and the second drive unit using a control signal, so that the first support unit and the second support unit can be placed in an appropriate tilted state according to the condition of the person being cared for.

[0020] Preferably, the control unit outputs a first signal to the first drive unit instructing the rotation of the first support unit, and after this command is completed, outputs a second signal to the first drive unit and the second drive unit instructing the rotation of the first support unit and the second support unit and further increasing the inclination angle of the first support unit.

[0021] According to this configuration, the control unit outputs a first signal to the first drive unit to command the rotation of the first support unit, and after this command is completed, outputs a second signal to the first drive unit and the second drive unit to command the rotation of the first support unit and the second support unit and to further increase the tilt angle of the first support unit, so that the care recipient can stand up from the bed with peace of mind without feeling like falling. It is preferable to rotate the first support unit and the second support unit simultaneously in the second operation.

[0022] Preferably, the rotation angles of the first support portion and the second support portion in the second operation are the same.

[0023] According to this configuration, since the rotation angles of the first support part and the second support part in the second motion are the same, it is possible to set the rotation speeds of the first support part and the second support part in the second motion to be the same. As a result, the care recipient can rotate in a comfortable state without feeling any discomfort.

[0024] Preferably, a rotation angle by which the first support portion rotates in response to a first signal is 2 to 5 degrees.

[0025] According to this configuration, by setting the rotation angle by which the first support part rotates in response to the first signal to a range of 2 to 5 degrees, the care recipient can easily stand up from a recumbent position and smoothly stand up from the bed. If the rotation angle by which the first support part rotates is smaller than 2 degrees or larger than 5 degrees, it is difficult for the care recipient in a recumbent position to smoothly stand up from the bed.

[0026] Preferably, a rotation angle by which the first support portion and the second support portion rotate in response to a second signal is 2 to 5 degrees.

[0027] According to this configuration, by setting the rotation angle by which the first support part and the second support part rotate in response to the second signal within a range of 2 to 5 degrees, the care recipient can easily stand up from a recumbent position and smoothly stand up from the bed. It is preferable to rotate the first support part and the second support part simultaneously in response to the second signal. If the rotation angle by which the first support part and the second support part rotate is smaller than 2 degrees or larger than 5 degrees, it is difficult for the care recipient in a recumbent position to smoothly stand up from the bed.

[0028] The present invention may be a fixed body to which the second support portion is fixed.

[0029] According to this configuration, since the second support section for supporting the upper body is fixed, an increase in the number of parts constituting the nursing bed can be suppressed, and cost reduction can be achieved.

[0030] The present invention includes a floor body having a first support section for supporting the lower body and a second support section for supporting the upper body, the floor body being divided into at least the first support section and the second support section in the width direction of the floor body, the first support section being a movable body that can rotate around a rotation axis that extends along the longitudinal direction of the floor body, and The pivot axis is located above the first support portion. The nursing bed is provided with .

[0031] According to this configuration, the inclination angle of the first support part can be freely set, so that the lower body can be inclined by inclining the first support part. This allows the care recipient to easily place the lower body on the floor and stand up. According to this configuration, when the first support part rotates, the care recipient on the bed is supported in a state where he or she is pressed against the first support part, thereby preventing the care recipient from worrying about falling off the bed.

[0032] Preferably, a drive portion is provided for rotating the first support portion about the rotation axis.

[0033] According to this configuration, since the bed is provided with a drive unit that rotates the first support part about the rotation axis, the bed has an improved rotation functionality, allowing the caregiver or the person being cared for to easily rotate the bed.

[0034] Preferably, the device further comprises a control unit which generates a control signal for instructing the operation of the drive unit and outputs the control signal to the drive unit.

[0035] According to this configuration, since the control unit that commands the operation of the drive unit by a control signal is provided, the first support unit can be placed in an appropriate tilted state in accordance with the state of the care recipient.

[0036] Preferably, the first support portion rotates in response to a control signal by an angle of 2 to 5 degrees.

[0037] According to this configuration, by setting the rotation angle of the first support part in the range of 2 to 5 degrees, the care recipient can easily stand up from a recumbent position and stand up smoothly from the bed. If the rotation angle of the first support part is smaller than 2 degrees or larger than 5 degrees, it is difficult for the care recipient in a recumbent position to stand up smoothly from the bed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] Hereinafter, an embodiment of a nursing bed of the present invention will be described in detail with reference to Figs.

[0040] FIG. 1 is a front view of a nursing bed 1. The nursing bed 1 includes a bed body 10 having a first support part for supporting the lower body, a first support part 11 for supporting the lower body, and a second support part 22 for supporting the upper body. The bed body 10 is divided into at least the first support part 11 and the second support part 22 along the width direction W of the bed body 10 (perpendicular to the paper surface in FIG. 1, see FIGS. 7 and 8), and the first support part 11 and the second support part 22 are movable bodies 11a and 22a that can rotate around a rotation axis RS that extends along the longitudinal direction L of the bed body 10. In the nursing bed 1, the first support part 11 can rotate around the rotation axis RS by operating the first drive part 30 according to a command from the control part 2, and the second support part 22 can rotate around the rotation axis RS by operating the second drive part 40 (indicated by an arrow S in FIGS. 7 and 8). The rotation of the first support section 11 and the rotation of the second support section 22 can be realized independently. The first support section 11 plays a role in supporting the lower body, and the second support section 22 plays a role in supporting the upper body. Furthermore, by operating the lifting drive section 50, the first support section 11 and the second support section 22 simultaneously move up and down the same distance, and by operating the reclining drive section 60, the tip section 22e of the second support section 22 rotates in the standing direction from the lying down position. The first drive section 30, the second drive section 40, the lifting drive section 50, and the reclining drive section 60 operate upon receiving commands from the control section 2.

[0041] In this embodiment, the nursing bed 1 is divided into two parts, the first support part 11 and the second support part 22, but is not limited thereto. For example, the nursing bed 1 may be divided into three parts by adding a part for supporting the buttocks.

[0042] In this embodiment, "supporting the lower body" means supporting the area below the thighs, and does not necessarily mean supporting the buttocks. Also, it is not necessary to support the entire thighs, and it is sufficient to support only a part of the thighs.

[0043] In addition, "supporting the upper body" means supporting the area from the back up, and does not necessarily mean supporting the waist and buttocks. Also, it is not necessary to support the entire back, but it is sufficient to support only a part of the back.

[0044] The rotation axis RS is located above the first support part 11 and the second support part 22, and extends in parallel to the first support part 11 and the second support part 22 in the longitudinal direction L of the bed body 10. Here, the longitudinal direction L is the direction in which the first support part 11 and the second support part 22 are arranged in a row. In addition, the rotation axis RS is located equidistant from both side ends extending along the longitudinal direction L of the nursing bed 1 in a side view.

[0045] 2, the lift drive unit 50 advances and retreats the piston 52a of the lift actuator 52, thereby causing the lift link mechanism 51 to rise and fall with rotation. One end of the lift actuator 52 is rotatably connected to a base 53, and the other end is rotatably connected to the lift link mechanism 51. By advancing and retreating the piston 52a, the lift actuator 52 and the lift link mechanism 51 rise and fall with rotation. The first support unit 11 and the second support unit 22 supported by the lift link mechanism 51 also rise and fall with the rise and fall of the lift link mechanism 51.

[0046] The lifting / lowering link mechanism 51 is a member for lifting and lowering the support frame 14. The support frame 14 supports the first support section 11 and the second support section 22. As shown in FIG. 3, the lifting / lowering link mechanism 51 has a structure in which lifting / lowering link members 56 and 57 are connected via a connecting bar 58, and one end of the lifting / lowering link members 56 and 57 is rotatably connected to the base 53 and the other end of the lifting / lowering link members 56 and 57. As a result of being connected by the connecting bar 58, the lifting / lowering link members 56 and 57 move and displace in synchronization with each other. A connecting member 59 for rotatably connecting the lifting / lowering actuator 52 is attached to the middle portion of the lifting / lowering link member 56.

[0047] 4 and 5, the reclining drive unit 60 has a reclining actuator 62 and a reclining link mechanism 61. One end of the reclining actuator 62 is rotatably connected to the second support frame 72, and the other end is rotatably connected to the reclining link mechanism 61. One end of the reclining link mechanism 61 is rotatably connected to the second support frame 72, and the other end is rotatably connected to the second support unit 22. An end of the second support unit 22 adjacent to the first support unit 11 is rotatably connected to the second support frame 72. In the reclining drive unit 60, the reclining link mechanism 61 moves up and down with the rotation of the reclining actuator 62 as the piston 62a of the reclining actuator 62 advances and retreats. As the piston 62a advances, the second support unit 22 rotates in a direction in which the tip portion 22e stands up from the lying down position. Furthermore, as the piston 62a moves backward, the second support portion 22 moves downward toward the second support frame 72 and returns to its original position while rotating the tip portion 22e downward in the figure.

[0048] The reclining link mechanism 61 has a pair of reclining link members 66, 66 and a connecting bar 67. One end of the reclining link member 66 is rotatably connected to the second support frame 72, and the other end is rotatably connected to the second support part 22. The middle part has a hinge part that allows each member to rotate. The connecting bar 67 is a member that connects the pair of reclining link members 66, 66, and an end part is rotatably connected to the middle part of the reclining link member 66. A connecting member 68 is attached to the middle part of the connecting bar 67 for rotatably connecting it to the reclining actuator 62.

[0049] The first support portion 11 is fixed to a first support frame 71. The first support portion 11 is supported by the support frame 14 via a first drive portion 30 (see FIG. 1). As shown in FIGS. 6, 7, and 8, the first drive portion 30 has a first actuator 31 and a pair of first guide portions 32. The first actuator 31 is located between the pair of first guide portions 32, 32. One end of the first actuator 31 is rotatably connected to the support frame 14, and the other end is rotatably connected to a connection frame 38 via a connection member 39. The connection frame 38 is a member that is bridged across both side ends of the first support frame 71.

[0050] The first guide section 32 is a member that is bridged across both side ends of the first support frame 71, and has an arc-shaped first guide frame 33. The first guide frame 33 is sandwiched between rollers 35 that are rotatably fixed to a guide frame fixing section 34. The guide frame fixing section 34 is fixed to the support frame 14.

[0051] The first guide part 32 rotates about the rotation center axis as the piston of the first actuator 31 moves forward and backward. Specifically, as the piston 31a moves forward, the first guide frame 33 rotates clockwise in FIG. 8, and as the piston 31a moves backward, the first guide frame 33 rotates counterclockwise.

[0052] The second support section 22 has an end portion adjacent to the first support section 11 rotatably fixed to the second frame. The second support section 22 is also supported by the support frame 14 via a second drive section 40 (see FIG. 1). As shown in FIG. 6, the second drive section 40 has a second actuator 41, a pair of second guide sections 42, 42, a guide frame fixing section 44, and a roller 45. The configurations of the second actuator 41, the second guide section 42, the guide frame fixing section 44, and the roller 45 are substantially the same as the configurations of the first actuator 31, the first guide section 32, the guide frame fixing section 34, and the roller 35, respectively, and therefore will not be described.

[0053] 9 shows the configuration of the control unit 2. The electronic control unit (hereinafter referred to as ECU) is composed of a microcomputer including a CPU, RAM, ROM, and an I / O interface (all not shown). An operation panel 5 is connected to the ECU 3, and signals issued from the operation panel 5 are input sequentially. A first actuator 31, a second actuator 41, a lift actuator 52, and a reclining actuator 62 are connected to the output side of the ECU 3.

[0054] The operation of the first support part 11 and the second support part 22 from the initial state when the operation panel 5 is operated will be described with reference to Figures 9 and 10. Here, the initial state refers to a state in which the nursing bed 1 is placed on a horizontal installation surface, the first support part 11 and the second support part 22 are horizontal to the installation surface, and the distance from the ground surface to the first support part 11 and the second support part 22 is minimum.

[0055] By pressing the push button PB0, the operation panel 5 is energized and is ready to send a signal to the ECU 3.

[0056] When push button PB1 is pressed, first actuator 31 and second actuator 41 operate, and pistons 31a and 41a move forward in proportion to the time push button PB1 is pressed. This causes first support portion 11 and second support portion 22 to move up the same distance at the same time (see FIG. 10(a)). The height to which they can move is determined by the distance pistons 31a and 41a can move forward.

[0057] When push button PB2 is pressed, the first actuator 31 and the second actuator 41 operate in accordance with the time that push button PB2 is pressed, and the pistons 31a and 41a in the forward moving state move backward in proportion to the time that push button PB2 is pressed. As a result, the first support portion 11 and the second support portion 22 in the raised state move downward the same distance at the same time (see FIG. 10(a)). The distance of descent is determined by the distance that the pistons can move backward.

[0058] When the push button PB3 is pressed, the reclining actuator 62 operates according to the pressing time, and the piston 62a moves forward. This causes the second support part 22 to rotate toward the first support part 11 (see FIG. 10(b)). The angle by which the rotation can be performed is determined by the distance the piston 62a can move forward.

[0059] When push button PB4 is pressed, reclining actuator 62 operates according to the duration of pressing, and piston 62a, which is in the forward position, moves backward. This causes second support part 22, which is in the rotating state, to rotate in a direction away from first support part 11 (see FIG. 10(b)). The rotation stops when it is positioned on the same plane as first support part 11. At this time, it is preferable that piston 62a has reached a distance where it cannot move backward any further.

[0060] When the push button PB5 is pressed, the first actuator 31 operates and the piston 31a moves forward. As a result, the first support 11 rotates from the horizontal state around the rotation axis RS within a range of 3 to 5 degrees (see FIG. 10(c). Hereinafter, the symbol "~" indicates a range). A more preferable rotation angle is 3 to 4 degrees. After the rotation of the first support 11 is completed, the first actuator 31 and the second actuator 41 operate simultaneously and the pistons 31a and 41a move forward. As a result, the first support 11 rotates further by 3 to 5 degrees, and the second support 22 rotates by 3 to 5 degrees (see FIG. 10(d)). A more preferable rotation angle is 3 to 4 degrees. This series of rotation operations is continuously executed by pressing the push button PB5. As a result, the first support 11 rotates by 6 to 10 degrees and the second support 22 rotates by 3 to 5 degrees in the same direction. By making the rotation angle of the first support part 11 that supports the lower body larger than the rotation angle of the second support part 22 that supports the upper body, the care recipient lying on the nursing bed 1 can easily get up from the nursing bed 1 and get down onto the floor, etc. By pressing the push button PB5 again, the first actuator 31 and the second actuator 41 are operated, and the first support part 11 and the second support part 22 return to their positions before they rotated.

[0061] When push button PB6 is pressed, the second actuator 41 is operated, and the piston 41a repeatedly moves forward and backward. As a result, the second support part 22 repeatedly rotates from the horizontal state around the rotation axis RS by ±3° in a cycle of approximately 5 seconds (see FIG. 10(e)). Pressing push button PB5 again stops the rotation, and the second support part 22 returns to its initial horizontal state. The rotation angle can be changed by pressing push button PB9 while the second support part 22 is rotating. Pressing it once changes the rotation angle to ±5°, pressing it twice changes the rotation angle to ±8°, and pressing it three times returns the rotation angle to the initial rotation angle of ±3°.

[0062] When push button PB7 is pressed, the first actuator 31 is operated, and the piston 31a repeatedly moves forward and backward. As a result, the first support part 11 repeatedly rotates from the horizontal state around the rotation axis RS by ±3° in a cycle of approximately 5 seconds (see FIG. 10(f)). Pressing push button PB5 again stops the rotation, and the second support part 22 returns to its initial horizontal state. The rotation angle can be changed by pressing push button PB9 while the first support part 11 is rotating. Pressing it once changes the rotation angle to ±5°, pressing it twice changes the rotation angle to ±8°, and pressing it three times returns the rotation angle to the initial rotation angle of ±3°.

[0063] When the push button PB8 is pressed, both the first actuator 31 and the second actuator 41 are operated, and the pistons 31a and 41a repeatedly move forward and backward. As a result, the first support 11 and the second support 22 synchronously rotate from the horizontal state around the rotation axis RS by ±3° in a cycle of about 5 seconds (see FIG. 10(g)). Pressing the push button PB5 again stops the rotation, and the first support 11 and the second support 22 return to their initial horizontal state. The rotation angle can be changed by pressing the push button PB9 while the first support 11 and the second support 22 are rotating. Pressing once changes the rotation angle to ±5°, pressing twice changes the rotation angle to ±8°, and pressing three times changes the initial rotation angle to ±3°. The first support 11 and the second support 22 rotate periodically at the same time, providing a sound sleep effect.

[0064] From the viewpoint of ensuring the safety of the care recipient, some limitations are imposed on the movement displacement of the first support part 11 and the second support part 22.

[0065] <Restriction 1> When push button PB3 is pressed to rotate second support portion 22, pressing any of push buttons PB6, 7, 8 will not rotate first support portion 11 or second support portion 22 about rotation axis RS.

[0066] <Restriction 2> When one of the push buttons PB5, 6, 7, or 8 is pressed while another push button PB5, 6, 7, or 8 is pressed, the signal generated when the other push button is pressed is not transmitted to the ECU 3. In other words, the operation of the first actuator 31, etc., when the other push button is pressed is not reflected.

[0067] <Restriction 3> When the first support portion 11 and the second support portion 22 are tilted, even if any of the push buttons PB5, 6, 7, and 8 is pressed, the signal generated when the push button is pressed is not transmitted to the ECU 3. That is, in this state, even if any of the push buttons PB5, 6, 7, and 8 is pressed, the first support portion 11 and the second support portion 22 do not rotate around the rotation axis RS.

[0068] <Modification> In this embodiment, the first support part 11 and the second support part 22 rotate independently, but this is not limited to the above. As shown in FIG. 11, the second support part 22 may be a fixed body 22b. In this case, the second drive part 40 is not required, and the number of parts required for the nursing bed 1 can be reduced. Also, as shown in FIGS. 12(a) and 12(b), the position of the rotation axis RS is not limited to above the first support part 11 and the second support part 22, and may be a position passing through the first support part 11 and the second support part 22.

[0069] The present embodiment is merely an example, and it is needless to say that it can be modified without departing from the technical spirit of the present invention. [Industrial Applicability]

[0070] The nursing bed according to the present invention is expected to have a sound sleep and relaxation effect, and can be used not only by those receiving care but also by healthy people, and therefore has great industrial applicability. [Explanation of symbols]
