  In the method disclosed in Patent Document 1, when washing the back of the care recipient, the caregiver needs to support the upper body of the care recipient and wash the back, and washing the back of the care recipient requires a great deal of labor from the caregiver. And

  In view of the above, an object of the present invention is to provide a nursing care bed with a bathtub that can easily wash the back of a care recipient.

[1] In order to achieve the above object, the present invention provides:
The lower part of the bed on which the lower body side of the care recipient can lie (for example, the bed lower part 5 of the embodiment; the same applies hereinafter), and the upper body side of the care recipient can lie on one end of the lower part of the bed so as to be swingable upward. A bed (for example, the bed 2 of the embodiment; hereinafter the same) having a connected bed top (for example, the bed upper 6 of the embodiment; the same applies hereinafter);
An elevating device for elevating the lower part of the bed (for example, the elevating device 8 of the embodiment; the same applies hereinafter);
A tub (for example, the tub 3 of the embodiment; the same applies hereinafter) that is located below the lower part of the bed and that can accommodate the lower part of the bed lowered by the elevating device;
An arm connected to the upper portion of the bed and extending upward (for example, the arm 9 of the embodiment; the same applies hereinafter);
A swinging member (for example, the swinging member 11 of the embodiment, which is the same hereinafter) swingably supported by the arm and hanging downward;
A table provided on the swing member (for example, the table 12 of the embodiment; the same applies hereinafter);
An upright portion (for example, one side wall 3a of the bathtub 3 of the embodiment, a leaf spring 13, a wire 14, an extension portion 10; the same applies hereinafter) for raising the bed upper portion;
With
When the lower part of the bed is lowered by the elevating device, the upper part of the bed is raised by the upright part corresponding to the lowering of the lower part of the bed, and the arm fixed to the upper part of the bed corresponds to the lowering of the elevating device. The table is positioned in the direction of the other side above the bed in a raised state by being inclined to the other side in a direction opposite to the one side.

  According to the present invention, the upper part of the bed is raised in response to the lowering of the lower part of the bed by the elevating device, and the table is positioned in the direction of the other side of the raised upper part of the bed. This allows the caregiver to change his posture from leaving his back on the top of the raised bed to leaning against the table, allowing the caregiver to support the caregiver without having to support the upper body. The back of the caregiver can be more easily washed than before.

[2] In the present invention,
The upright portion includes a wire (for example, the wire 14 of the bathtub 3 of the embodiment, the same applies hereinafter) having one end connected to the lower portion of the arm and the other end connected to the lower portion of the bed.
When the bed upper part is in an ascending state in which the bed lower part is raised by the elevating device, the bed is in a state in which the arm is pulled up by the wire and is prevented from rising.
When the lower part of the bed is in a lowered state lowered by the elevating device, it is preferable that the wire is loosened by the lowering of the lower part of the bed, and the upper part of the bed is raised by the upright part.

  According to the present invention, the arm can be switched between the vertical position and the inclined position via the wire by the lifting / lowering movement of the lifting / lowering device, and there is no need to incorporate a drive source dedicated to the arm into the standing portion, and only the power of the lifting / lowering device is used. The state of the arm can be switched, and the configuration of the nursing bed with a bathtub can be simplified.

[3] In the present invention, in the case where the state of the arm is switched by using the lifting / lowering motion of the lifting / lowering device using a wire,
The upright portion includes an elastic member (for example, the leaf spring 13 of the embodiment; the same applies hereinafter) that swings the upper part of the bed upward by its own restoring force,
When the bed upper part is in the ascending state in which the bed lower part is raised by the elevating device, the arm is pulled by the wire against the self-restoring force of the elastic member. Yes,
When the lower part of the bed is in the lowered state lowered by the elevating device, the wire is loosened in response to the lowering of the lower part of the bed, and the upper part of the bed is raised by the self-restoring force of the elastic member. Is preferred.

  The upright portion is constituted by the upper edge of the bathtub (for example, one side wall 3a of the bathtub 3 of the embodiment; the same applies hereinafter), and the back surface of the upper part of the bed is brought into contact with the upper edge of the bathtub as the upright portion. It is conceivable to raise the upper part of the bed by pushing up the upper edge of the bathtub as the lower part of the bed descends. However, if an attempt is made to raise the bed only by pressing the upper portion of the bed to which the arm is fixed against the upper edge of the bathtub, the load on the bathtub may become too large.

  Therefore, as described above, if the upright portion is formed not only by the upper edge of the bathtub, but also by an elastic member that swings the upper part of the bed upward by its own restoring force instead of the upper edge of the bathtub, The load on the bathtub when raising the upper part can be reduced.

  [4] In the present invention, it is preferable that the table is configured to be movable in the one or the other direction with respect to the swing member.

  According to this configuration, the table located in front of the care recipient (the other side) can be retreated from the care recipient to the other side, so that the space in front of the care recipient (the other side) can be increased. Since it is possible to wash the chest and abdomen of the care recipient, it can be easily washed.

  [5] Further, in the present invention, an extending portion (for example, the extending portion 10 of the embodiment; the same applies hereinafter) extending toward the lower portion of the bed is provided at an upper end side of the arm, and the bed is provided. In a state where the lower portion is lowered and the arm is inclined, the extending portion is configured to contact an upper edge of the bathtub (for example, the other side wall 3c of the bathtub 3 of the embodiment; the same applies hereinafter). Is preferred.

  According to the present invention, since the arm fixed to the upper part of the bed is supported by the upper edge of the bathtub via the extension in the inclined state inclined to the other side, the arm can be stably maintained in the inclined posture state. Can be.

Explanatory drawing which shows typically the state which lowered | hung the bed lower part of the nursing care bed with a bathtub of this embodiment, and accommodated in the bathtub.

  An embodiment of the nursing bed with a bathtub according to the present invention will be described with reference to the drawings. Referring to FIG. 1, a nursing care bed 1 with a bathtub according to the present embodiment includes a bed 2 on which a care recipient can lie, a bathtub 3 positioned below the bed 2, and a base on which the bathtub 3 is placed. 4 is provided.

  The bed 2 includes a bed lower part 5 on which the lower body side of the care recipient can lie, a bed upper part 6 on which the upper body side of the care recipient can lie and is connected to one end of the bed lower part 5 so as to swing upward. And a lower end extension 7 connected to the other end of the lower part 5 so as to swing upward.

  An elevating device 8 is provided in the bathtub 3 so as to be able to switch between a bathing state in which the bed lower part 5 is raised and lowered and the bed lower part 5 is accommodated in the bathtub 3 and a state in which the bed lower part 5 is out of the bathtub 3. Have been.

  Arms 9 extending from both side edges of the bed upper part 6 are fixed to one end of the bed upper part 6 so as to extend upward. At the upper end side of the arm 9 (the upper end in the figure, it is sufficient if it is above a position where the swinging member 11 described later is connected), an extension is provided that extends from the upper end of the arm 9 toward the other side. A unit 10 is provided. Inside each of the arms 9, a swinging member 11 whose upper end portion is swingably supported and whose lower end hangs downward is provided.

  At the lower ends of both swing members 11, a rectangular plate-shaped table substrate 12a is provided horizontally. A table body 12b having the same shape as the table substrate 12a is rotatably connected to one side edge of the table substrate 12a so as to be rotatable upward. In the present embodiment, the table 12 is constituted by the table substrate 12a and the table main body 12b, and the table main body 12b can be rotated upward to be superimposed on the upper surface of the table substrate 12a.

  In the present embodiment, the folded state in which the table body 12a is overlaid by the rotation of the table main body 12b, and one plate-like table 12 extending from one side edge of the table substrate 12a to one side. The extended state is a state in which the table 12 in the present embodiment is retracted, and the extended state is a state in which the table 12 in the present embodiment is advanced. When the table 12 is not used, the space in front (the other side) of the care recipient can be widened by folding the table body 12b on the table substrate 12a.

  The method of moving the table 12 is not limited to the configuration in which the table main body 12b is rotatably attached to the table substrate 12a. Other configurations, for example, the table main body 12b is provided at the lower ends of both swing members It may be configured to be able to slide forward and backward along a given horizontally extending guide rail.

  The bed upper part 6 extends toward one side from the side wall 3 a on one side of the bathtub 3. One end 13a of the leaf spring 13 is connected to the back surface (lower surface) of the bed upper part 6. The other end 13 b of the leaf spring 13 is connected to the outer surface of the side wall 3 a on one side of the bathtub 3.

  One end 14a of the wire 14 is connected to the lower ends of the arms 9. The wire 14 passes through a groove provided in the base 4 (not shown) and a through hole (not shown) in the bottom wall 3b of the bathtub 3 to pass through the back surface (lower surface) of the bottom wall 3b of the bathtub 3 and the lower part 5 of the bed. It is wound around a pulley 15 rotatably attached to the back surface (lower surface). The other end 14 b of the wire 14 is connected to a connecting member 16 provided to extend upward on the surface (upper surface) of the bottom wall 3 b of the bathtub 3. As shown by dotted lines in FIGS. 1 and 2, by adjusting the position of the connecting member 16, the bed is extended so that the distal end of the extending portion 10 firmly contacts the upper edge of the other side wall 3 c of the bathtub 3. The amount of slack of the wire 14 with respect to the amount of lowering of the lower portion 5 can be adjusted.

  As shown in FIG. 1, when the bed lower part 5 is raised by the lifting device 8, the bed upper part 6 is in a horizontal posture state, the arm 9 is in a vertical posture state, and the wire 14 is a leaf spring 13. In order to maintain the current state of the bed upper part 6 and the arm 9 against the self-restoring force of the bed, the tension state is tight without being loosened.

  When the lower part 5 of the bed is lowered by the elevating device 8 from the state of FIG. 1, the wire 14 is loosened corresponding to the lowering of the lower part 5 of the bed, and the wire 14 is loosened by the self-restoring force of the leaf spring 13 as much as the wire 14 is loosened. The arm 6 rises up about the connecting portion with the bed lower part 5, and the arm 9 also inclines to the other side at the same time. Since the upper end of the arm 9 is provided with the extending portion 10 and the table 12 extending to the other side, once the arm 9 is in the inclined posture, the arm 9 is connected to the wire 14 regardless of the self-restoring force of the leaf spring 13. In response to the loosening, it is further inclined to the other side. Therefore, the self-restoring force required for the leaf spring 13 can be relatively small. When lowering the bed lower part 5, the lower end extension part 7 rotates upward with respect to the bed lower part 5 and folds. Accordingly, when the lower bed portion 5 is out of the bathtub 3 and is in a raised state, the lower end extension portion 7 can be rotated to the other side to increase the substantial length of the bed 2 and a relatively large It is possible to secure a sufficient space for sleeping even for a caregiver who needs care.

  As shown in FIG. 2, when the lower state of the bed 5 is shifted to the lowering state where the lowering is completed, the tip of the extension 10 provided at the upper end of the arm 9 contacts the upper edge of the side wall 3 c on the other side of the bathtub 3. Touch Thereby, one side of the arm 9 is fixed to the bed upper part 6, and the other side of the arm 9 is supported by the upper edge of the side wall 3 c on the other side of the bathtub 3 via the extending part 10, so that the arm 9 is inclined. Can be stably maintained.

  As shown in FIG. 2, when the arm 9 is in the inclined position, the upper end of the swinging member 11 is connected to the arm 9 so as to be swingable. 11 remains vertical. For this reason, the table 12 provided at the lower end of the swinging member 11 is located on the other side of the bed upper part 6 which has risen to the standing state.

  The table 12 can be arranged so as to be arranged on one side of the table substrate 12a by rotating the table body 12b folded on the table substrate 12a as required, and can be spread out as a single plate. Thus, the care recipient can relax on the large table 12. The connection position between the swing member 11 and the arm 9 can be adjusted with a bolt or the like in the vertical direction. When the table 12 is used, the connection position between the swing member 11 and the arm 9 is lowered so that the swing member 11 is lowered. It may be adjusted. Alternatively, the swinging member 11 may be provided with an expansion / contraction mechanism (not shown) so that the swinging member 11 can be expanded and contracted by an electric motor (not shown) so that the table is at an appropriate position.

  The extension unit 10 is provided with a television monitor 17 (receiver). Thus, the care recipient can enjoy the image transferred to the television monitor 17 without raising his / her upper body, not only during bathing but also when lying on the flat bed 2. Further, since the extension portion 10 is provided on the arm 9, the center of gravity of the arm 9 including the extension portion 10 moves to the other side of the arm 9, and the extension portion 10 vertically moves the arm 9. It has potential energy for switching from the posture to the inclined posture. Therefore, the wire 14 opposes the force by which the arm 9 by the extension 10 tries to shift to the inclined posture.

  When the bed lower part 5 descends, the bed upper part 6 comes into contact with the upper edge of the side wall 3a on one side of the bathtub 3, thereby assisting the rising operation of the bed upper part 6. At this time, in order to reduce the frictional force when the back surface (lower surface) of the bed upper part 6 and the upper edge of the side wall 3a on one side of the bathtub 3 contact, the upper edge of the side wall 3a on one side of the bathtub 3 is A roller 18 is provided.

  In the present embodiment, the upright part of the present invention is constituted by the side wall 3a on one side of the bathtub 3, the leaf spring 13, the wire 14, and the extending part 10.

  According to the nursing bed 1 with a bathtub of the present embodiment, the bed upper part 6 rises in response to the lowering of the bed lower part 5 by the elevating device 8, and the table 12 is located in the direction of the other side of the raised bed upper part 6. This allows the care recipient to change his / her posture from the state in which his / her back is left on the raised bed upper part 6 to the state in which it leans against the table 12, and the caregiver does not support the upper body of the care recipient, and Can wash the back of the care recipient more easily than before.

  Further, according to the nursing bed 1 with a bathtub of the present embodiment, the arm 9 can be switched between the vertical position and the inclined position via the wire 14 by the lifting / lowering movement of the lifting / lowering device 8, and the upright portion dedicated to the arm 9 is provided. There is no need to incorporate a drive source, the state of the arm 9 can be switched only by the power of the lifting device 8, and the configuration of the nursing care bed 1 with a bathtub can be simplified.

  Here, the upright portion is constituted only by the upper edge of the side wall 3a on one side of the bathtub 3, and the back surface of the bed upper portion 6 is brought into contact with the upper edge of the one side wall 3a as the upright portion, and the lower portion 5 of the bed is formed. It is also conceivable that the bed upper part 6 is raised by pushing up at the upper edge of the side wall 3a on the one side in accordance with the downward movement. However, if the bed 9 to which the arm 9 is fixed is pressed only against the upper edge of the bathtub 3 to raise the bed, the load on the bathtub 3 may be too large.

  Therefore, in the nursing care bed 1 with a bathtub of the present embodiment, the upright portion includes not only the upper edge of the bathtub 3 but also a leaf spring 13 as an elastic member that swings the bed upper part 6 upward by its own restoring force. Therefore, the load on the bathtub 3 when the bed upper part 6 is raised can be reduced.

  In addition, according to the nursing care bed 1 with a bathtub of the present embodiment, the table 12 is rotated by folding the table main body 12b located in front (the other side) of the care recipient, thereby folding the table 12 on the table substrate 12a. From one side to the other side. For this reason, since the space in front (the other side) of the care recipient can be increased, the chest and abdomen of the care recipient can be easily washed when washing.

  Further, according to the nursing care bed 1 with a bathtub of the present embodiment, the arm 9 fixed to the bed upper part 6 is supported by the upper edge of the side wall 3c on the other side of the bathtub 3 via the extending part 10 in the inclined state. Therefore, the inclined posture state of the arm 9 can be stably held.

  In the present embodiment, the upright portion is configured by the side wall 3a on one side of the bathtub 3, the leaf spring 13, the wire 14, and the extending portion 10. However, the upright portion of the present invention is not limited to this. Instead, another configuration may be used as long as the bed upper part 6 can be raised to be in the standing state. For example, even if the upright portion is constituted only by the upper edge of the bathtub in contact with the back surface (lower surface) of the upper part of the bed as the lower part of the bed descends, the "care-requiring person according to the present invention leaves the back on the raised upper part of the bed. The caregiver can easily wash the back of the care recipient without the need for the caregiver to support the upper body of the care recipient. Can be obtained.

  Further, in the present embodiment, the one using the leaf spring 13 as the elastic member has been described, but the elastic member of the present invention is not limited to this, and the upper part of the bed can be swung upward by a self-restoring force. Any other material, for example, a coil spring or elastic rubber may be used.
